Description

Technical Field

[0001] This invention relates to the field of home appliances, and particularly to a bearing processing method, a bearing, a compressor, home appliances, and electronic devices. Background Technology

[0002] To process compressor bearings, some technologies employ die casting or casting to create the bearing casting, followed by rough machining using methods such as turning, milling, and drilling. Finally, the bearing's inner bore and flange face are ground to obtain the finished bearing. This die casting or casting method has a long processing cycle and makes it difficult to quickly adjust to the required structural form of the rough-machined part. Summary of the Invention

[0003] The main objective of this invention is to propose a bearing processing method that aims to improve the problems of long processing cycles and difficulty in quickly adjusting the structure of the rough-machined bearings according to the required rough-machined product, which are inherent in existing die-cast or cast bearings.

[0004] To achieve the above objectives, the present invention provides an example of a bearing processing method, which includes the following steps:

[0085]

[0086] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0087] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0088] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0089] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0090] The plurality mentioned in the examples of this invention is at least two (including two).

[0091] The air conditioning compressor is the core component of an air conditioning system, often referred to as the main unit of the refrigeration unit. A compressor typically has a cylinder, which has an upper bearing and a lower bearing. A crankshaft passes through the upper and lower bearings and can rotate relative to them under the drive of a motor. The bearing processing method described in this invention can be either the upper bearing processing method or the lower bearing processing method. For ease of description, the upper bearing will be used as an example below.

[0092] An upper bearing typically includes a flange, a hub mounted on the flange, and an outer ring. The crankshaft passes through the hub and flange. In some technologies, the flange, hub, and outer ring are molded or die-cast. Because the upper bearing needs to mate with the crankshaft and cylinder, errors in the position of the hub, flange, and outer ring can easily cause the compressor to seize, affecting its performance. Furthermore, bearings molded by casting or die-casting cannot adjust the position of the hub, flange, and outer ring, leading to a higher defect rate.

[0093] An example of this invention provides a bearing processing method, comprising the following steps:

[0094] Provide a sheet material;

[0095] The sheet metal is processed to form a flange portion and multiple protrusions surrounding the outer periphery of the flange portion; and

[0096] A center hole is machined on the flange and a first pipe fitting is provided. The first pipe fitting is connected to the flange, and the center hole and the first pipe fitting are coaxially arranged.

[0097] The bearing processing method of the present invention can separately form the flange portion and the hub portion, thereby simplifying the forming steps of the flange portion and the hub portion. On the one hand, it can be used to process bearings with a flange portion thickness greater than 5mm. During the processing, defects such as cracks are less likely to occur, which can help improve the processing performance of the product. On the other hand, by separately connecting and fixing the first pipe to the flange portion, it is convenient to align the first pipe to the flange portion, thereby improving the installation accuracy of the hub portion and the flange portion, reducing the occurrence of misalignment, and thus improving the accuracy of the bearing product and reducing the misalignment problem after the bearing product is installed.

[0098] The present invention also provides an example of a bearing, including a flange, a first pipe and a plurality of protrusions; the flange has a central hole; the plurality of protrusions are respectively connected to the flange and are arranged around the outer periphery of the flange; the first pipe is connected to the flange; the first pipe is coaxially arranged with the central hole.

[0099] This example demonstrates how setting up protrusions to form an outer ring facilitates the molding and processing of the outer ring. By installing the first pipe fitting onto the flange, the first pipe fitting can serve as a hub. The flange and the first pipe fitting can be molded separately for installation as needed. The installation positions of the first pipe fitting and the flange can be adjusted as required, reducing molding errors during overall molding and thus improving the installation accuracy of the first pipe fitting and the flange.

[0100] The bearings described in the above examples of the present invention can be used in compressors, which can be used in refrigeration equipment such as refrigerators and air conditioners.

[0101] The present invention also provides an example of an electronic device storing a bearing machining program, which, when executed by a processor, implements the steps of the bearing machining method as described in the above example.

[0102] Please refer to the following: Figure 1 , Figure 7 and Figure 8 This invention provides a bearing processing method, comprising the following steps:

[0103] S100: Provides a sheet material.

[0104] In this example, the sheet material can be made of stainless steel, and the sheet material can be in sheet form. The thickness of the sheet material can be consistent with the thickness of the required bearing.

[0105] S200: The sheet metal is processed to form a flange 10 and a plurality of protrusions 14 arranged around the outer periphery of the flange 10.

[0106] In this example, the flange 10 can be entirely disc-shaped, serving as the main structure of the bearing.

[0107] Multiple protrusions 14 are located on the outer periphery of the flange portion 10, and are connected to the flange portion 10 to form an integral structure. In this example, the multiple protrusions 14 can be evenly spaced along the outer periphery of the flange portion 10. Optionally, the number of protrusions 14 is not less than three, so that the protrusions 14 form a support structure on the outer periphery of the flange portion 10, which facilitates the mating of the flange portion 10 with other structures. In this example, the shape and size of the multiple protrusions 14 can be substantially consistent to facilitate subsequent mating with other structures.

[0108] In this example, the sheet metal is processed by cutting or other processes to make the flange 10 and the plurality of protrusions 14 form an integral structure.

[0109] S300: A center hole 11 is machined on the flange portion 10 and a first pipe fitting 30 is provided, and the first pipe fitting 30 is connected to the flange portion 10, wherein the center hole 11 and the first pipe fitting 30 are coaxially arranged.

[0110] The center hole 11 can be a through hole that passes through the thickness direction of the flange portion 10, and the center hole 11 can be a circular hole.

[0111] The first pipe fitting 30 can be generally cylindrical, and different parts of the first pipe fitting 30 along the axial direction can have different outer diameters, so that when the first pipe fitting 30 is projected in a plane parallel to the axial direction of the first pipe fitting 30, the outer edge of the first pipe fitting 30 can form a stepped shape. The first pipe fitting 30 has a shaft hole, and the shaft hole of the first pipe fitting 30 is coaxially arranged with the central hole 11.

[0112] The first pipe fitting 30 is connected to the flange portion 10, meaning that the first pipe fitting 30 and the flange portion 10 are connected and fixed to each other. In this example, welding or other connection methods can be used to fix the first pipe fitting 30 to the flange portion 10.

[0113] In this example, a flange 10 and multiple protrusions 14 are formed on the sheet metal. The flange 10 serves as the main structure of the bearing, and the multiple protrusions 14 can be used to connect to external structures. By forming multiple protrusions 14 on the flange 10, when docking with other structures, since the total area of ​​the docking surfaces of the multiple protrusions 14 with other structures is smaller than the total area of ​​the outer periphery of the flange 10, when it is necessary to adjust the shape and / or position of the docking positions of the multiple protrusions 14 with other structures, only the protrusions 14 need to be adjusted, thereby reducing the amount of adjustment work required. In this example, the first pipe 30 can form the hub of the bearing. After the flange 10 is formed, the first pipe 30 is connected to the flange 10. During the installation of the first pipe 30, the position of the first pipe 30 can be adjusted so that the shaft hole of the first pipe 30 can be better aligned with the center hole 11, thereby improving the coaxiality of the shaft hole of the first pipe 30 and the center hole 11, and improving the bearing machining accuracy.

[0114] In this example, the flange 10 and the first pipe fitting 30 can be assembled after being formed separately, which can reduce the complexity of the bearing forming equipment, facilitate the adjustment of the bearing forming equipment, and allow multiple parts to be formed at the same time to shorten the processing cycle and reduce energy consumption.

[0115] The machining method described in this example can be used to machine bearings with significant thickness, especially those with a thickness of not less than 5 mm. Since the flange 10 and the first pipe fitting 30 are both molded separately, and the sheet metal has a relatively fixed thickness, when the bearing thickness is large, the flange 10 and the protrusion 14 can be cut and molded separately before the first pipe fitting 30 is fixed to the flange 10. This reduces the increase in internal defects caused by casting or die-casting processes when the bearing is thicker, thus helping to improve bearing quality.

[0116] In this example, the protrusion 14 can be used to form the outer ring 40 of the bearing, or to mount the outer ring 40 of the bearing. Since the length of the outer periphery of the protrusion 14 is less than the length of the outer periphery of the flange 10, the total area of ​​the required machining parts can be reduced when the protrusion 14 is machined to form the outer ring 40 of the bearing, thus reducing machining costs and energy consumption. When the protrusion 14 is used as an intermediate connecting part between the outer ring 40 of the bearing and the flange 10, the protrusion 14 can deform to a certain extent when the outer ring 40 is mounted on the outside of the protrusion 14, thereby facilitating the installation and position adjustment of the outer ring 40, and making it easier to coaxially mount the outer ring 40 with the center hole 11, which helps to improve the installation accuracy of the outer ring 40. Due to the arrangement of multiple protrusions 14, the overall weight of the bearing can be reduced while maintaining the structural strength of the bearing.

[0117] In this example, in step S300, the order of steps of forming a center hole 11 on the flange 10 and providing a first pipe fitting 30 and connecting the first pipe fitting 30 to the flange 10 can be interchanged. That is, the first pipe fitting 30 is first installed on the flange 10, and then a center hole 11 coaxial with the first pipe fitting 30 is formed on the flange 10.

[0118] Optionally, in step S300 above, after forming a center hole 11 on the flange portion 10, a first pipe fitting 30 is provided. A plug-in portion 32 is provided on the first pipe fitting 30. The plug-in portion 32 is inserted into the center hole 11 to initially position the first pipe fitting 30 and the center hole 11. Then, the first pipe fitting 30 is connected and fixed to the flange portion 10. In this example, the plug-in portion 32 can have a clearance fit with the center hole 11 or a transition fit with the center hole 11.

[0119] In step S300 of this example, the first pipe 30 can be cut or milled to form a preset length and preset shape.

[0120] Please refer to the following: Figure 2 , Figure 9 and Figure 10 In some examples, after step S200 above, the bearing machining method further includes the following steps:

[0121] S400: An outer ring 40 is formed by machining the outer periphery of multiple bumps 14.

[0122] Multiple protrusions 14 are distributed on the outer periphery of the flange portion 10. The line connecting the outer periphery of the multiple protrusions 14 is roughly circular, and the outer ring 40 is fitted around the outer periphery of the multiple protrusions 14.

[0123] The outer ring 40 is connected and fixed to the plurality of protrusions 14 so that the outer ring 40 cannot move relative to the plurality of protrusions 14. In this example, the protrusions 14 can be connected to the plurality of protrusions 14 by welding so that the outer ring 40 is limited to the outer periphery of the plurality of protrusions 14.

[0124] The outer ring 40 is annular, and the outer periphery of the outer ring 40 can be coaxially arranged with the first pipe 30 and the central hole 11.

[0125] Since the outer ring 40 is connected and fixed to multiple protrusions 14, the position of the outer ring 40 can be finely adjusted during installation to allow for relative adjustment of the flange 10 and the outer ring 40 as needed.

[0126] In this example, step S300 can be performed after step S400, or step S400 can be performed after step S300. Since the outer ring 40 is fitted around the outer periphery of the multiple protrusions 14, the adjustability of the outer ring 40 is relatively improved. This allows for convenient adjustment of the machining steps as needed, ensuring the bearing machining corresponds to the bearing machining equipment, improving the flexibility of the bearing machining process, and helping to reduce machining costs. Because the outer ring 40 is connected to the outer periphery of the multiple protrusions 14, the coaxiality of the outer ring 40 and the center hole can be adjusted by adjusting the relative position of the outer ring 40.

[0127] Please refer to the following: Figure 3 , Figure 9 and Figure 10 In some examples, step S400 includes:

[0128] S410: Provide a second fitting, which is fitted onto the outer periphery of the plurality of protrusions 14.

[0129] The second pipe fitting is generally a hollow tubular structure, with an inner and outer annular surface. The line connecting the outer peripheries of the multiple protrusions 14 is generally circular. The second pipe fitting is fitted onto the outer periphery of the multiple protrusions 14, forming an inner-outer nested state. In this example, the second pipe fitting can be made of steel. Before fitting the second pipe fitting onto the outer periphery of the multiple protrusions 14, the second pipe fitting can be cut and / or ground to form a preset length and / or shape. In this example, before fitting the second pipe fitting onto the outer periphery of the multiple protrusions 14, at least one protrusion 14 can be ground and cut to adjust the size of the protrusion 14.

[0130] S420: Connect the second fitting to a plurality of protrusions 14, and the second fitting forms an outer ring 40.

[0131] The inner annular surface of the second pipe fitting is connected to a plurality of protrusions 14, so that the second pipe fitting is fixed to the outer periphery of the plurality of protrusions 14, forming an outer ring 40. Optionally, the second pipe fitting and the plurality of protrusions 14 can be interference-fitted to fix the second pipe fitting and the plurality of protrusions 14 to each other. Optionally, the second pipe fitting and the protrusions 14 can be welded to each other to fix the second pipe fitting and the plurality of protrusions 14 to each other. In this case, the second pipe fitting and the plurality of protrusions 14 can be transition-fitted. Optionally, after the second pipe fitting and the plurality of protrusions 14 are interference-fitted, the second pipe fitting and the protrusions 14 are welded to each other for fixation.

[0132] In this example, by directly fitting the second pipe fitting onto the outside of multiple protrusions 14 to form an outer ring 40, the position of the second pipe fitting can be adjusted during the process of fitting the second pipe fitting and connecting and fixing the second pipe fitting to the multiple protrusions 14, so that the outer ring surface of the second pipe fitting can be coaxial with the central hole 11. Since the total area of ​​the outer periphery of the multiple protrusions 14 is relatively smaller than the total area of ​​the outer periphery of the flange 10, the welding area required for welding the second pipe fitting to the multiple protrusions 14 will be relatively reduced when connecting and fixing the second pipe fitting to the multiple protrusions 14, thereby reducing the energy consumption required for installation.

[0133] By installing the second fitting after forming multiple protrusions 14, the second fitting and the multiple protrusions 14 can be formed separately. This simplifies the bearing processing equipment and facilitates separate quality control of different parts of the bearing. Compared to processes such as casting or die casting, it reduces the mutual interference and forces between the flange 10 and the outer ring 40, thereby reducing structural defects in the bearing product. By forming the second fitting and flange 10 separately, defects such as flange 10 deformation or cracks at the connection between the flange 10 and the outer ring 40 caused by stamping can be reduced, contributing to improved bearing product quality.

[0134] Please refer to the following: Figure 9 In some examples, the thickness L1 of the sheet metal is not less than 5 mm, and the thickness of the flange 10 and / or the protrusion 14 can be equal to the thickness of the sheet metal. The thickness of the flange 10 mentioned in this example refers to the thickness of the flange 10 along the axial direction of the central hole 11, and the axial direction of the flange 10 can be consistent with the axial direction of the central hole. Optionally, the thickness of the sheet metal can be selected as 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, or other desired thickness values.

[0135] Please refer to the following: Figure 9 In some examples, in step S200 above, the protrusion 14 and the flange 10 each have an outer periphery, and the distance L2 between the outer periphery of the protrusion 14 and the outer periphery of the flange 10 is not less than 5mm. In this example, the outer periphery of the protrusion 14 can be directly connected and fixed to the inner ring surface of the second pipe fitting. By limiting the distance between the outer periphery of the protrusion 14 and the flange 10, it is convenient to cut and shape the protrusion 14. In this example, the distance between the outer periphery of multiple protrusions 14 and the outer periphery of the flange 10 can be equal or unequal. When the distance between the outer periphery of the protrusion 14 and the outer periphery of the flange 10 is less than 5mm, the machinable space for the protrusion 14 is reduced when installing the second pipe fitting, thus reducing the adjustable space for installing the second pipe fitting.

[0136] In some examples, in step S200 above, the protrusion 14 and the flange 10 each have an outer periphery, and the distance L2 between the outer periphery of the protrusion 14 and the outer periphery of the flange 10 does not exceed 50mm. In this example, when the distance between the outer periphery of the protrusion 14 and the outer periphery of the flange 10 exceeds 50mm, the space between adjacent protrusions 14 increases. When the protrusion 14 is connected and positioned with the second pipe fitting, the gap between the second pipe fitting and the flange 10 increases, which may lead to a decrease in the structural strength of the bearing. In this example, by ensuring that the distance between the outer periphery of the protrusion 14 and the outer periphery of the flange 10 does not exceed 50mm, the protrusion 14 can be easily adjusted to improve the installation freedom of the outer ring 40, while ensuring that the bearing product has a preset structural strength.

[0137] In some examples, in step S200 above, the protrusion 14 and the flange 10 each have an outer periphery, and the distance L2 between the outer periphery of the protrusion 14 and the outer periphery of the flange 10 is not less than 5 mm and not more than 50 mm. In this example, L2 can be 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, or any other value within the above range.

[0138] Please refer to the following: Figure 4 , Figures 11 to 13 In some examples, step 410 includes:

[0139] S430: Multiple protrusions 14 are bent toward the same side of the flange portion 10 to form multiple outer edge portions 20.

[0140] The flange portion 10 has a first surface 12, and a plurality of protrusions 14 are bent toward one side of the first surface 12 to form an outer edge portion 20. The end of the outer edge portion 20 away from the flange portion 10 can extend substantially along the axial direction of the flange portion 10. In this example, the plurality of protrusions 14 can be bent at 90° toward the first surface 12 to form the outer edge portion 20. The outer edge portion 20 and the flange portion 10 are projected in a plane parallel to the axial direction of the flange portion 10, and the outer edge portion 20 can be partially protruding from the first surface 12.

[0141] S440: An outer ring 40 is formed by machining the outer periphery of multiple outer edge portions 20.

[0142] The outer edge portion 20 has an outer peripheral surface away from the axis of the flange portion 10. The line connecting the outer peripheries of the multiple outer edge portions 20 is generally circular. The outer ring 40 is fitted around the outer periphery of the multiple outer edge portions 20 so that the outer edge portion 20 serves as an intermediate connecting member between the outer ring 40 and the flange portion 10.

[0143] In this example, by bending multiple protrusions 14 to form the outer edge 20, the connection area between the protrusions 14 and the outer ring 40 can be increased, which helps to improve the connection strength between the outer ring 40 and the outer edge 20. Since the outer edge 20 is formed by bending multiple protrusions 14, defects such as porosity that exist in existing casting and die casting processes can be avoided. In this example, bending multiple protrusions 14 toward the same side of the flange 10 is suitable for bearings with larger thicknesses, especially bearings where the thickness of the flange 10 is greater than 5mm. Since multiple protrusions 14 are bent to form the outer edge 20, there are gaps between the multiple protrusions 14. When multiple protrusions 14 are bent, the connection between the outer edge 20 and the flange 10 is less prone to defects such as breakage. At the same time, multiple protrusions 14 can distribute the traction force generated on the flange 10 during bending, thereby reducing the deformation of the flange 10 and helping to improve the structural strength of the bearing. In this example, multiple protrusions 14 are bent to form the outer edge 20, which can improve the problem of stamping inconvenience in the existing stamping process, reduce product defects generated in the stamping process, and thus help improve product quality.

[0144] Please refer to the following: Figure 5 , Figures 11 to 13 In some examples, step S440 includes:

[0145] S441: Provide a second fitting, which is fitted onto the outer periphery of the plurality of outer edges 20.

[0146] The line connecting the outer peripheries of the multiple outer edge portions 20 is roughly circular, and the second pipe has an overall annular structure. The second pipe is fitted around the outer periphery of the multiple outer edges so that the second pipe can be fitted onto the outside of the multiple outer edge portions 20.

[0147] S442: The second fitting is connected to a plurality of outer edges 20, and the second fitting forms an outer ring 40.

[0148] The second pipe fitting can be welded and fixed to multiple outer edges 20, so that the second pipe fitting is fixed to the outer periphery of the multiple outer edges 20. In this example, the second pipe fitting can be cut and / or milled to form a preset length and preset shape.

[0149] In this example, an outer ring 40 is formed by fitting a second pipe fitting over multiple outer edge portions 20. During the fitting of the second pipe fitting and the process of connecting and fixing the second pipe fitting to the multiple outer edge portions 20, the position of the second pipe fitting can be adjusted so that the outer ring surface of the second pipe fitting can be coaxial with the central hole 11. Since the total area of ​​the outer periphery of the multiple outer edge portions 20 is relatively smaller than the total area of ​​the outer periphery of the flange portion 10, the welding area required for welding the second pipe fitting to the multiple outer edge portions 20 is relatively reduced when connecting and fixing the second pipe fitting to the multiple outer edge portions 20, thereby reducing the energy consumption required for installation.

[0150] By installing the second fitting after forming multiple outer edge portions 20, the second fitting and the multiple outer edge portions 20 can be formed separately. This simplifies the bearing processing equipment and facilitates separate quality control of different parts of the bearing. Compared to processes such as casting or die casting, it reduces the mutual interference and forces between the flange portion 10 and the outer ring 40, thereby reducing structural defects in the bearing product. By forming the second fitting and flange portion 10 separately, defects such as flange portion 10 deformation or cracks at the connection between the flange portion 10 and the outer ring 40 caused by stamping can be reduced, contributing to improved bearing product quality.

[0151] Please refer to the following: Figure 6 , Figures 14 to 16 In some examples, another method for forming the outer ring 40 has been proposed. After performing step S200, the bearing machining method further includes the following steps:

[0152] S500: Multiple protrusions 14 are bent toward the same side of the flange portion 10 to form multiple outer edge portions 20.

[0153] The flange portion 10 has a first surface 12, and a plurality of protrusions 14 are bent toward one side of the first surface 12 to form an outer edge portion 20. The end of the outer edge portion 20 away from the flange portion 10 can extend substantially along the axial direction of the flange portion 10. In this example, the plurality of protrusions 14 can be bent toward the first surface 12 to form the outer edge portion 20. The outer edge portion 20 and the flange portion 10 are projected in a plane parallel to the axial direction of the flange portion 10, and the outer edge portion 20 can be partially protruding from the first surface 12. In this example, the bending angle of the plurality of protrusions 14 can be 90°, or the bending angle of the plurality of protrusions 14 can be less than 90°.

[0154] S600: The outer peripheral surface of the outer edge portion 20 is machined so that the line connecting the outer peripheral surfaces of the multiple outer edge portions 20 forms a cylindrical surface.

[0155] The outer edge portion 20 has an outer peripheral surface away from the axis of the flange portion 10. At least one of the outer peripheral portions 20 can be machined so that the line connecting the outer peripheral surfaces of the plurality of outer edge portions 20 forms a cylindrical surface. When the outer edge portion 20 is projected into a plane perpendicular to the axial direction of the flange portion 10, the line connecting the outer peripheral surfaces of the plurality of outer edge portions 20 is circular. Optionally, the outer peripheral surfaces of the plurality of outer edge portions 20 can be made to have a smooth arc surface by grinding and / or cutting. The outer peripheral surfaces of the plurality of outer edge portions 20 respectively form a part of the outer ring 40, in which case the outer ring 40 and the outer edge portion 20 are integrally formed.

[0156] In this example, an outer ring 40 is formed integrally with the outer edge portion 20 by machining the outer peripheral surfaces of multiple outer edge portions 20. When grinding or cutting the outer edge portion 20, the position and angle of the arc surface formed by the outer peripheral surface of the outer edge portion 20 can be easily controlled so that the outer ring 40 formed after machining can have better coaxiality with the center hole 11.

[0157] In this example, step S500 can be performed after step S300, or step S300 can be performed after step S500. The center hole 11, the first pipe 30, and the cylindrical surface can be coaxially arranged.

[0158] Please refer to the following: Figure 7 In some examples, in step S200 above, the protrusion 14 and the flange 10 each have an outer periphery, and the distance between the outer periphery of the protrusion 14 and the outer periphery of the flange 10 is not less than 10 mm. During the bending operation of multiple protrusions 14, when the distance between the outer periphery of the protrusion 14 and the outer periphery of the flange 10 is less than 10 mm, the length of the outer edge portion 20 formed after bending the protrusion 14 along the axial direction of the flange 10 is too small. When the outer ring 40 is formed, the axial length of the outer ring 40 is relatively small, which can easily lead to a decrease in bearing stability. When step S422 above is used, the area available for machining the outer peripheral surface of the outer edge portion 20 is relatively large, and the axial length of the outer ring 40 can be extended as needed.

[0159] Please refer to the following: Figure 7 In some examples, in step S200 above, the distance between the outer periphery of the protrusion 14 and the outer periphery of the flange 10 does not exceed 50 mm. During the bending operation of multiple protrusions 14, when the distance between the outer periphery of the protrusion 14 and the outer periphery of the flange 10 exceeds 50 mm, the axial length of the outer edge portion 20 formed by bending is too large along the axial direction of the flange 10. When performing step S422 above, the required processing area increases, which may lead to an increase in the energy consumption required for bearing processing.

[0160] Please refer to the following: Figure 7In some examples, in step S200 above, the protrusion 14 and the flange 10 each have an outer periphery, and the distance between the outer periphery of the protrusion 14 and the outer periphery of the flange 10 is not less than 10 mm and not more than 50 mm. In this example, the distance between the outer periphery of the protrusion 14 and the outer periphery of the flange 10 can be 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, or any other value within the above range. In this example, by limiting the distance between the outer periphery of the protrusion 14 and the outer periphery of the flange 10, on the one hand, it is convenient to bend the protrusion 14, thereby facilitating the compensation of the axial length of the outer ring 40 formed by processing, improving the structural strength of the bearing product; on the other hand, it can reduce the energy consumption of the processing process and improve processing efficiency.

[0161] Please refer to the following: Figure 16 In some examples, in step S500 above, the bending angle α of the protrusion 14 is not less than 20°. During the bending operation of the protrusion 14, when the bending angle of the protrusion 14 is less than 20°, because the bending of the protrusion 14 is relatively small, the length of the outer edge 20 along the axial direction of the flange portion 10 is small. Under the premise of ensuring the radial thickness of the outer edge 20 and the outer ring 40, the area that can be machined when machining the outer periphery of the outer edge 20 is relatively small, resulting in a shorter axial length of the machined outer ring 40, which reduces the structural strength of the bearing.

[0162] Please refer to the following: Figure 16 In some examples, in step S500 above, the bending angle α of the protrusion 14 does not exceed 75°. During the bending operation of the protrusion 14, the outer peripheral surface of the outer edge portion 20 formed by bending forms a surface to be processed for cutting and / or grinding. When the bending angle of the protrusion 14 exceeds 75°, it is inconvenient to compensate for the axial length of the cylindrical surface when a cylindrical surface is formed on the outer periphery of the outer edge portion 20 along the axial direction of the flange portion 10.

[0163] Please refer to the following: Figure 16 In some examples, in step S500 above, the bending angle α of the protrusion 14 is not less than 20° and does not exceed 75°. In this example, the bending angle of the protrusion 14 can be 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75° or other angle values. In this example, by limiting the bending angle of the protrusion 14, after the protrusion 14 is bent to form the outer edge 20, the length of the processed surface can be increased during the cutting and / or grinding process of the outer periphery of the outer edge 20, thereby compensating for the axial length of the formed cylindrical surface and compensating for the dimensional accuracy of the bending process.

[0164] Please refer to the following: Figure 12and Figure 17 In some examples, in step S430 or S500, the flange portion 10 has a first surface 12, and a plurality of protrusions 14 are bent toward one side of the first surface 12 of the flange portion 10 to form a plurality of outer edges 20.

[0165] Please see Figure 12 In some examples, in step S300, the first fitting 30 is connected to the first surface 12.

[0166] The outer edge 20 of the first pipe fitting 30 is projected in a plane parallel to the axial direction of the flange 10, and both the first pipe fitting 30 and the outer edge 20 protrude from the first surface 12. When the bearing is fitted with other structures, the first pipe fitting 30 and the outer edge 20 are less likely to interfere with other structures, thereby reducing the space required for bearing installation.

[0167] Please refer to the following: Figure 7 and Figure 15 In some examples, the number of protrusions 14 is not less than three; the protrusions 14 have an outer periphery away from the flange portion 10, and the length L3 of the outer periphery of the protrusions 14 along the circumferential direction of the flange portion 10 is not less than 10 mm. In this example, by limiting the length of the outer periphery of the protrusions 14 along the circumferential direction of the flange portion 10, the problem of reduced bearing structural strength due to the total length of the outer periphery of the protrusions 14 being too small can be reduced.

[0168] When the operation of bending the protrusion 14 toward the same side of the flange 10 to form the outer edge 20 is performed, the length of the end of the outer edge 20 away from the flange 10 along the circumferential direction of the flange 10 is equal to the length of the outer periphery of the protrusion 14.

[0169] In this example, the length L3 of the outer periphery of the bump 14 can be 10mm, 12mm, 15mm, 18mm, 20mm or other length values.

[0170] Please refer to the following: Figure 7 , Figure 3 , Figure 16 as well as Figure 17 In step S300, the first pipe fitting 30 has a first mounting surface 31, and the flange portion 10 has a second mounting surface 13 connected to the first mounting surface 31. Along the radial direction of the central hole 11, the width L4 of the first mounting surface 31 is not less than 8 mm.

[0171] In this example, the first mounting surface 31 is a surface on the first pipe fitting 30 facing the flange portion 10. By limiting the width of the first mounting surface 31, when the first pipe fitting 30 and the flange portion 10 are connected, the first mounting surface 31 and the second mounting surface 13 of the flange portion 10 are connected and fixed together. The second mounting surface 13 of the flange portion 10 can be on the same plane as the first surface 12 in any of the above examples, or it can be on a different plane from the first surface 12. In this example, the first mounting surface 31 is the surface on the first pipe fitting 30 that connects and mates with the flange portion 10. The first mounting surface 31 can be fixed to the second mounting surface 13 of the flange portion 10 by welding. By ensuring that the width of the first mounting surface 31 is not less than 8mm, the first pipe fitting 30 can better mate with the flange portion 10, ensuring the connection strength between the first pipe fitting 30 and the flange portion 10, thereby improving the structural strength of the bearing.

[0172] In this example, the first mounting surface 31 can be perpendicular to the axial direction of the first pipe fitting 30, or it can be set not perpendicular to the axial direction of the first pipe fitting 30. Optionally, the width L4 of the first mounting surface 31 can be 8mm, 10mm, 12mm, 15mm or other values.

[0173] Please see Figure 7 and Figure 8 The present invention also provides an example of a bearing, including a flange portion 10, a plurality of protrusions 14, and a first pipe fitting 30. The flange portion 10 has a central hole 11; the plurality of protrusions 14 are respectively connected to the flange portion 10, and the plurality of protrusions 14 are arranged around the outer periphery of the flange portion 10; the first pipe fitting 30 is connected to the flange portion 10; the first pipe fitting 30 is coaxially arranged with the central hole 11.

[0174] In this example, the sheet material can be stainless steel, and the sheet material can be sheet-like. The thickness of the sheet material can be consistent with the thickness of the required bearing. In this example, the flange 10 can be disc-shaped, and the flange 10 serves as the main structure of the bearing.

[0175] Multiple protrusions 14 are located on the outer periphery of the flange portion 10, and are connected to the flange portion 10 to form an integral structure. In this example, the multiple protrusions 14 can be evenly spaced along the outer periphery of the flange portion 10. Optionally, the number of protrusions 14 is not less than three, so that the protrusions 14 form a support structure on the outer periphery of the flange portion 10, which facilitates the mating of the flange portion 10 with other structures. In this example, the shape and size of the multiple protrusions 14 can be substantially consistent to facilitate subsequent mating with other structures.

[0176] In this example, the sheet metal is processed by cutting or other processes to make the flange 10 and the plurality of protrusions 14 form an integral structure.

[0177] The center hole 11 can be a through hole that passes through the thickness direction of the flange portion 10, and the center hole 11 can be a circular hole.

[0178] The first pipe fitting 30 can be generally cylindrical, and different parts of the first pipe fitting 30 along the axial direction can have different outer diameters, so that when the first pipe fitting 30 is projected in a plane parallel to the axial direction of the first pipe fitting 30, the outer edge of the first pipe fitting 30 forms a stepped shape. The first pipe fitting 30 has a shaft hole, and the shaft hole of the first pipe fitting 30 is coaxially arranged with the central hole 11.

[0179] The first pipe fitting 30 is connected to the flange portion 10, meaning that the first pipe fitting 30 and the flange portion 10 are connected and fixed to each other. In this example, welding or other connection methods can be used to fix the first pipe fitting 30 to the flange portion 10.

[0180] In this example, a flange 10 and multiple protrusions 14 are formed on the sheet metal. The flange 10 serves as the main structure of the bearing, and the multiple protrusions 14 can be used to connect to external structures. By forming multiple protrusions 14 on the flange 10, when docking with other structures, since the total area of ​​the docking surfaces of the multiple protrusions 14 with other structures is smaller than the total area of ​​the outer periphery of the flange 10, when it is necessary to adjust the shape and / or position of the docking positions of the multiple protrusions 14 with other structures, only the protrusions 14 need to be adjusted, thereby reducing the amount of adjustment work required. In this example, the first pipe 30 can form the hub of the bearing. After the flange 10 is formed, the first pipe 30 is connected to the flange 10. During the installation of the first pipe 30, the position of the first pipe 30 can be adjusted so that the shaft hole of the first pipe 30 can be better aligned with the center hole 11, thereby improving the coaxiality of the shaft hole of the first pipe 30 and the center hole 11, and improving the bearing machining accuracy.

[0181] In this example, the flange 10 and the first pipe fitting 30 can be assembled after being formed separately, which can reduce the complexity of the bearing forming equipment, facilitate the adjustment of the bearing forming equipment, and allow multiple parts to be formed at the same time to shorten the processing cycle and reduce energy consumption.

[0182] The machining method described in this example can be used to machine bearings with significant thickness, especially those with a thickness of not less than 5 mm. Since the flange 10 and the first pipe fitting 30 are both molded separately, and the sheet metal has a relatively fixed thickness, when the bearing thickness is large, the flange 10 and the protrusion 14 can be cut and molded separately before the first pipe fitting 30 is fixed to the flange 10. This reduces the increase in internal defects caused by casting or die-casting processes when the bearing is thicker, thus helping to improve bearing quality.

[0183] In this example, the protrusion 14 can be used to form the outer ring 40 of the bearing, or to mount the outer ring 40 of the bearing. Since the length of the outer periphery of the protrusion 14 is less than the length of the outer periphery of the flange 10, the total area of ​​the required machining parts can be reduced when the protrusion 14 is machined to form the outer ring 40 of the bearing, thus reducing machining costs and energy consumption. When the protrusion 14 is used as an intermediate connecting part between the outer ring 40 of the bearing and the flange 10, the protrusion 14 can deform to a certain extent when the outer ring 40 is mounted on the outside of the protrusion 14, thereby facilitating the installation and position adjustment of the outer ring 40, and making it easier to coaxially mount the outer ring 40 with the center hole 11, which helps to improve the installation accuracy of the outer ring 40. Due to the arrangement of multiple protrusions 14, the overall weight of the bearing can be reduced while maintaining the structural strength of the bearing.

[0184] Optionally, the first pipe fitting 30 is provided with a plug-in portion 32, which is inserted into the central hole 11 to initially position the first pipe fitting 30 and the central hole 11, and then the first pipe fitting 30 is connected and fixed to the flange portion 10. In this example, the plug-in portion 32 can have a clearance fit with the central hole 11 or a transition fit with the central hole 11.

[0185] Please refer to the following: Figure 9 and Figure 10 The bearing also includes an outer ring 40 sleeved on the outer periphery of multiple protrusions 14, and the outer ring 40, the central hole 11 and the first tube 30 are coaxially arranged.

[0186] Multiple protrusions 14 are distributed around the outer periphery of the flange portion 10. The line connecting the outer peripheries of the multiple protrusions 14 is approximately circular, and an outer ring 40 is fitted around the outer periphery of the multiple protrusions 14. The outer ring 40 is connected and fixed to the multiple protrusions 14 so that the outer ring 40 cannot move relative to the multiple protrusions 14. In this example, the protrusions 14 can be connected to the multiple protrusions 14 by welding so that the outer ring 40 is limited to the outer periphery of the multiple protrusions 14. The outer ring 40 is annular, and its outer periphery can be coaxially arranged with the first pipe fitting 30 and the central hole 11. Since the outer ring 40 is connected and fixed to the multiple protrusions 14, the position of the outer ring 40 can be finely adjusted during installation to adjust the flange portion 10 and the outer ring 40 relative to each other as needed.

[0187] Please refer to the following: Figures 11 to 13 A second pipe fitting is fitted around the outer periphery of multiple protrusions 14, and the second pipe fitting forms an outer ring 40.

[0188] The second pipe fitting is generally a hollow tubular structure, with an inner and outer annular surface. The line connecting the outer peripheries of the multiple protrusions 14 is generally circular. The second pipe fitting is fitted onto the outer periphery of the multiple protrusions 14, forming an inner-outer nested state. In this example, the second pipe fitting can be made of steel. Before fitting the second pipe fitting onto the outer periphery of the multiple protrusions 14, the second pipe fitting can be cut and / or ground to form a preset length and / or shape. In this example, before fitting the second pipe fitting onto the outer periphery of the multiple protrusions 14, at least one protrusion 14 can be ground and cut to adjust the size of the protrusion 14.

[0189] The inner annular surface of the second pipe fitting is connected to a plurality of protrusions 14, so that the second pipe fitting is fixed to the outer periphery of the plurality of protrusions 14, forming an outer ring 40. Optionally, the second pipe fitting and the plurality of protrusions 14 can be interference-fitted to fix the second pipe fitting and the plurality of protrusions 14 to each other. Optionally, the second pipe fitting and the protrusions 14 can be welded to each other to fix the second pipe fitting and the plurality of protrusions 14 to each other. In this case, the second pipe fitting and the plurality of protrusions 14 can be transition-fitted. Optionally, after the second pipe fitting and the plurality of protrusions 14 are interference-fitted, the second pipe fitting and the protrusions 14 are welded to each other for fixation.

[0190] In this example, by directly fitting the second pipe fitting onto the outside of multiple protrusions 14 to form an outer ring 40, the position of the second pipe fitting can be adjusted during the process of fitting the second pipe fitting and connecting and fixing the second pipe fitting to the multiple protrusions 14, so that the outer ring surface of the second pipe fitting can be coaxial with the central hole 11. Since the total area of ​​the outer periphery of the multiple protrusions 14 is relatively smaller than the total area of ​​the outer periphery of the flange 10, the welding area required for welding the second pipe fitting to the multiple protrusions 14 will be relatively reduced when connecting and fixing the second pipe fitting to the multiple protrusions 14, thereby reducing the energy consumption required for installation.

[0191] By installing the second fitting after forming multiple protrusions 14, the second fitting and the multiple protrusions 14 can be formed separately. This simplifies the bearing processing equipment and facilitates separate quality control of different parts of the bearing. Compared to processes such as casting or die casting, it reduces the mutual interference and forces between the flange 10 and the outer ring 40, thereby reducing structural defects in the bearing product. By forming the second fitting and flange 10 separately, defects such as flange 10 deformation or cracks at the connection between the flange 10 and the outer ring 40 caused by stamping can be reduced, contributing to improved bearing product quality.

[0192] Please refer to the following: Figure 9In some examples, the thickness L1 of the sheet metal is not less than 5 mm, and the thickness of the flange 10 and / or the protrusion 14 can be equal to the thickness of the sheet metal. The thickness of the flange 10 mentioned in this example refers to the thickness of the flange 10 along the axial direction of the central hole 11. Optionally, the thickness of the sheet metal can be selected as 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, or other desired thickness values.

[0193] Please refer to the following: Figure 9 In some examples, the protrusion 14 and the flange 10 each have an outer periphery, and the distance L2 between the outer periphery of the protrusion 14 and the outer periphery of the flange 10 is not less than 5 mm. In this example, the outer periphery of the protrusion 14 can be directly connected and fixed to the inner ring surface of the second pipe fitting. By limiting the distance between the outer periphery of the protrusion 14 and the flange 10, the cutting and forming of the protrusion 14 is facilitated. In this example, the distance between the outer periphery of multiple protrusions 14 and the outer periphery of the flange 10 can be equal or unequal. When the distance between the outer periphery of the protrusion 14 and the outer periphery of the flange 10 is less than 5 mm, the machinable space for the protrusion 14 is reduced when installing the second pipe fitting, thus reducing the adjustable space for installing the second pipe fitting.

[0194] In some examples, the protrusion 14 and the flange 10 each have an outer periphery, and the distance L2 between the outer periphery of the protrusion 14 and the outer periphery of the flange 10 does not exceed 50 mm. In this example, when the distance between the outer periphery of the protrusion 14 and the outer periphery of the flange 10 exceeds 50 mm, the space between adjacent protrusions 14 increases. When the protrusion 14 is connected and positioned with the second pipe fitting, the gap between the second pipe fitting and the flange 10 increases, which may lead to a decrease in the structural strength of the bearing. In this example, by ensuring that the distance between the outer periphery of the protrusion 14 and the outer periphery of the flange 10 does not exceed 50 mm, the protrusion 14 can be easily adjusted to improve the installation freedom of the outer ring 40, while ensuring that the bearing product has a predetermined structural strength.

[0195] In some examples, the distance L2 between the outer periphery of the protrusion 14 and the outer periphery of the flange 10 is not less than 5 mm and not more than 50 mm. In this example, L2 can be 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, or any other value within the above range.

[0196] Please see Figures 11 to 13 In some examples, multiple protrusions 14 bend toward the same side of the flange portion 10 to form multiple outer edges 20, and a second pipe fitting is fitted around the outer periphery of the outer edges 20, forming an outer ring 40.

[0197] The lines connecting the outer peripheries of the multiple outer edge portions 20 are generally circular, and the second pipe has an overall annular structure. The second pipe is fitted onto the outer periphery of the multiple outer edges so that it can be fitted onto the outside of the multiple outer edge portions 20. The second pipe can be welded and fixed to the multiple outer edge portions 20 to secure it to the outer periphery of the multiple outer edge portions 20. In this example, the second pipe can be cut and / or milled to form a preset length and preset shape.

[0198] In this example, an outer ring 40 is formed by fitting a second pipe fitting over multiple outer edge portions 20. During the fitting of the second pipe fitting and the process of connecting and fixing the second pipe fitting to the multiple outer edge portions 20, the position of the second pipe fitting can be adjusted so that the outer ring surface of the second pipe fitting can be coaxial with the central hole 11. Since the total area of ​​the outer periphery of the multiple outer edge portions 20 is relatively smaller than the total area of ​​the outer periphery of the flange portion 10, the welding area required for welding the second pipe fitting to the multiple outer edge portions 20 is relatively reduced when connecting and fixing the second pipe fitting to the multiple outer edge portions 20, thereby reducing the energy consumption required for installation.

[0199] By installing the second fitting after forming multiple outer edge portions 20, the second fitting and the multiple outer edge portions 20 can be formed separately. This simplifies the bearing processing equipment and facilitates separate quality control of different parts of the bearing. Compared to processes such as casting or die casting, it reduces the mutual interference and forces between the flange portion 10 and the outer ring 40, thereby reducing structural defects in the bearing product. By forming the second fitting and flange portion 10 separately, defects such as flange portion 10 deformation or cracks at the connection between the flange portion 10 and the outer ring 40 caused by stamping can be reduced, contributing to improved bearing product quality.

[0200] Please refer to the following: Figures 14 to 16 In some examples, multiple protrusions 14 bend toward the same side of the flange portion 10 to form multiple outer edges 20, and the line connecting the outer peripheral surfaces of the multiple outer edges 20 forms a cylindrical surface.

[0201] The flange portion 10 has a first surface 12, and a plurality of protrusions 14 are bent toward one side of the first surface 12 to form an outer edge portion 20. The end of the outer edge portion 20 away from the flange portion 10 can extend substantially along the axial direction of the flange portion 10. In this example, the plurality of protrusions 14 can be bent toward the first surface 12 to form the outer edge portion 20. The outer edge portion 20 and the flange portion 10 are projected in a plane parallel to the axial direction of the flange portion 10, and the outer edge portion 20 can be partially protruding from the first surface 12. In this example, the bending angle of the plurality of protrusions 14 can be 90°, or the bending angle of the plurality of protrusions 14 can be less than 90°.

[0202] The outer edge portion 20 has an outer peripheral surface away from the axis of the flange portion 10. At least one of the outer peripheral portions 20 can be machined so that the line connecting the outer peripheral surfaces of the plurality of outer edge portions 20 forms a cylindrical surface. When the outer edge portion 20 is projected into a plane perpendicular to the axial direction of the flange portion 10, the line connecting the outer peripheral surfaces of the plurality of outer edge portions 20 is circular. Optionally, the outer peripheral surfaces of the plurality of outer edge portions 20 can be made to have a smooth arc surface by grinding and / or cutting. The outer peripheral surfaces of the plurality of outer edge portions 20 respectively form a part of the outer ring 40, in which case the outer ring 40 and the outer edge portion 20 are integrally formed.

[0203] In this example, an outer ring 40 is formed integrally with the outer edge portion 20 by machining the outer peripheral surfaces of multiple outer edge portions 20. When grinding or cutting the outer edge portion 20, the position and angle of the arc surface formed by the outer peripheral surface of the outer edge portion 20 can be easily controlled so that the outer ring 40 formed after machining can have better coaxiality with the center hole 11.

[0204] In some examples, the bending angle α of the protrusion 14 is not less than 20°. During the bending operation of the protrusion 14, when the bending angle of the protrusion 14 is less than 20°, due to the smaller bending of the protrusion 14, the length of the outer edge 20 along the axial direction of the flange portion 10 is smaller. Under the premise of ensuring the radial thickness of the outer edge 20 and the outer ring 40, the area that can be machined when machining the outer periphery of the outer edge 20 is relatively small, resulting in a shorter axial length of the machined outer ring 40, which reduces the structural strength of the bearing.

[0205] Please refer to the following: Figure 16 In some examples, the bending angle α of the protrusion 14 does not exceed 75°. During the bending operation of the protrusion 14, the outer peripheral surface of the outer edge portion 20 formed by bending forms a surface to be processed for cutting and / or grinding. When the bending angle of the protrusion 14 exceeds 75°, it is inconvenient to compensate for the axial length of the cylindrical surface when machining a cylindrical surface on the outer periphery of the outer edge portion 20 along the axial direction of the flange portion 10.

[0206] Please refer to the following: Figure 16 In some examples, the bending angle α of the protrusion 14 is not less than 20° and does not exceed 75°. In this example, the bending angle of the protrusion 14 can be 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75° or other angle values. In this example, by limiting the bending angle of the protrusion 14, after the protrusion 14 is bent to form the outer edge 20, the length of the machined surface can be increased during the cutting and / or grinding process of the outer periphery of the outer edge 20, thereby compensating for the axial length of the formed cylindrical surface and compensating for the dimensional accuracy of the bending process.

[0207] Please see Figure 13In some examples, the sheet metal has a first surface 12, and a plurality of protrusions 14 are bent toward one side of the first surface 12 of the flange portion 10 to form a plurality of outer edges 20; a first pipe 30 is connected to the first surface 12.

[0208] The outer edge 20 of the first pipe fitting 30 is projected in a plane parallel to the axial direction of the flange 10, and both the first pipe fitting 30 and the outer edge 20 protrude from the first surface 12. When the bearing is fitted with other structures, the first pipe fitting 30 and the outer edge 20 are less likely to interfere with other structures, thereby reducing the space required for bearing installation.

[0209] Please see Figure 15 In some examples, the number of bumps 14 is not less than three. The bumps 14 have an outer periphery away from the flange portion 10, and the length of the outer periphery of the bumps 14 along the circumferential direction of the flange portion 10 is not less than 10 mm.

[0210] In this example, by limiting the length of the outer periphery of the protrusion 14 along the circumferential direction of the flange portion 10, the problem of reduced bearing structural strength caused by the total length of the outer periphery of the protrusion 14 being too small can be reduced.

[0211] In this example, the length L3 of the outer periphery of the protrusion 14 can be 10mm, 12mm, 15mm, 18mm, 20mm, or other length values. When the outer edge 20 is formed by bending, the length of the end of the outer edge 20 away from the flange 10 along the circumferential direction of the flange 10 is equal to the length of the outer periphery of the protrusion 14.

[0212] Please see Figure 16 In some examples, the first fitting 30 has a first mounting surface 31, and the flange portion 10 has a second mounting surface 13 connected to the first mounting surface 31. The width of the first mounting surface 31 is not less than 8 mm along the radial direction of the central hole 11.

[0213] In this example, the first mounting surface 31 is a surface on the first pipe fitting 30 facing the flange portion 10. By limiting the width of the first mounting surface 31, when the first pipe fitting 30 and the flange portion 10 are connected, the first mounting surface 31 and the second mounting surface 13 of the flange portion 10 are connected and fixed together. The second mounting surface 13 of the flange portion 10 can be on the same plane as the first surface 12 in any of the above examples, or it can be on a different plane from the first surface 12. In this example, the first mounting surface 31 is the surface on the first pipe fitting 30 that connects and mates with the flange portion 10. The first mounting surface 31 can be fixed to the second mounting surface 13 of the flange portion 10 by welding. By ensuring that the width of the first mounting surface 31 is not less than 8mm, the first pipe fitting 30 can better mate with the flange portion 10, ensuring the connection strength between the first pipe fitting 30 and the flange portion 10, thereby improving the structural strength of the bearing.

[0214] In this example, the first mounting surface 31 can be perpendicular to the axial direction of the first pipe fitting 30, or it can be set not perpendicular to the axial direction of the first pipe fitting 30. Optionally, the width L4 of the first mounting surface 31 can be 8mm, 10mm, 12mm, 15mm or other values.
