Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to a multi-hole flanged bearing. Background Technology

[0002] Flanged bearings, also known as flanged bushings, not only provide support and lubrication for the rotating shaft in the radial direction, but also withstand a certain force in the axial direction. Therefore, flanged bearings have a wide range of applications and are often used in machinery with a lot of vibration.

[0003] Patent document CN211924735U discloses a self-lubricating flanged bearing, including an arc-shaped flange and fixing screws. Two sets of fixing screws are provided, and the two sets of fixing screws are respectively screwed together with the left and right sides of the upper end of the arc-shaped flange. A tubular bearing is screwed onto the middle of the upper end of the arc-shaped flange. Multiple sets of solid lubricant are interlaced within the tubular bearing. A trapezoidal ring is fixedly connected to the upper end of the tubular bearing. This self-lubricating flanged bearing, by providing a receiving cavity on the arc-shaped flange that holds a tension spring, allows for a more stable connection between the bearing and the mounting base. The I-shaped concave groove adapts to installation in different orientations, improving flexibility. By providing symmetrically structured internal convex grooves on the inner and outer surfaces of the tubular bearing, the solid lubricant can flow along the oblique direction of the grooves, achieving simultaneous lubrication of both inner and outer surfaces, thus improving lubrication efficiency.

[0004] In the above scheme, the flanged bearing has two symmetrical through holes at the flange and is installed by corresponding screw bolts. The installation method is relatively fixed and lacks flexibility. If the installation conditions of the equipment change, the installation structure may need to be redesigned or modified. The load distribution is relatively concentrated on the two holes, which is prone to stress concentration. Especially under high load or large vibration conditions, the bolts may loosen, which may affect the service life of the bearing and the operational stability of the equipment. Therefore, it is necessary to provide a multi-hole flanged bearing to solve the shortcomings of the existing technology. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-hole flanged bearing.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A multi-hole flanged bearing includes a bearing body and a flange. The inner wall of the bearing body has a circumferential array of cylindrical holes, each of which is inlaid with a graphite column. The side of the flange away from the bearing body has a circumferential array of irregular grooves, and the side of the flange close to the bearing body has a circumferential array of bolt holes. The bolt holes pass through the irregular grooves, and the bolt holes correspond one-to-one with the irregular grooves. The bolt holes have internal threads. The bolts pass through the bolt holes to connect the flange to the corresponding holes of external mechanical parts, thereby fixing the bearing body.

[0008] The present invention is further configured such that the bearing body and the flange have the same axis, and the bearing body and the flange are integrally formed.

[0009] The present invention is further configured such that the graphite columns correspond one-to-one with the cylindrical holes, and the size and number of the graphite columns are consistent with those of the cylindrical holes.

[0010] The present invention is further configured such that the distance between the centers of adjacent cylindrical holes is 45 degrees.

[0011] The present invention is further configured such that the end of the irregular groove away from the bearing body is an arc, and the end of the irregular groove close to the bearing body is a semicircle, the axis of the semicircle is consistent with the axis of the bolt hole, and the diameter of the semicircle is larger than the diameter of the bolt hole.

[0012] The present invention is further configured such that the distance between the axes of adjacent bolt holes is 20 degrees.

[0013] The present invention is further configured such that the bolt hole is a through hole and the depth of the irregular groove is less than half the thickness of the flange.

[0014] The present invention is further provided that the inner side of the bearing body away from the flange has a chamfer.

[0015] The present invention is further provided with marking blocks on both sides of the flange.

[0016] In summary, this utility model has the following beneficial effects:

[0017] The flanged circumferential array of this invention is provided with bolt holes, offering more installation options and allowing installation at different angles and positions. This better adapts to various complex mechanical structures and installation space constraints. Multiple holes can distribute the load more evenly, reducing the stress on individual holes and thus improving the bearing's load-bearing capacity and stability. When subjected to large radial or axial loads, the holes in the circumferential array can better disperse the force, avoiding damage caused by localized stress concentration. The installation position and angle of the bearing can be fine-tuned by selecting different hole positions, improving installation accuracy. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] Example 1:

[0027] In this embodiment, as Figure 1-5 As shown, the present invention proposes a multi-hole flanged bearing, comprising a bearing body 1 and a flange 2. The inner wall of the bearing body is provided with a circumferential array of cylindrical holes, each of which is inlaid with a graphite column 3. The side of the flange away from the bearing body is provided with a circumferential array of irregular grooves 4, and the side of the flange close to the bearing body is provided with a circumferential array of bolt holes 5. The bolt holes pass through the irregular grooves, and the bolt holes correspond one-to-one with the irregular grooves. The bolt holes are provided with internal threads. The bolts pass through the bolt holes to connect the flange to the corresponding holes of external mechanical parts, thereby fixing the bearing body.

[0028] In this example, the graphite column acts as a self-lubricant, reducing wear and achieving maintenance-free lubrication.

[0029] In this example, bolts can be inserted into each of the multiple bolt holes, or bolts can be inserted into some of the bolt holes symmetrically. The choice can be made freely according to the working conditions and accuracy requirements.

[0030] In this example, the circumferential array of flanges features bolt holes, providing more installation options and allowing installation at different angles and positions. This better adapts to various complex mechanical structures and installation space constraints. For example, in equipment with limited space and specific requirements for installation angles, the holes in the circumferential array make it easier to install the bearing in the appropriate position without requiring large-scale modifications to the equipment structure. Multiple holes can distribute the load more evenly, reducing the stress on a single hole and thus improving the bearing's load-bearing capacity and stability. When subjected to large radial or axial loads, the holes in the circumferential array can better disperse the force, avoiding damage caused by localized stress concentration. The installation position and angle of the bearing can be fine-tuned by selecting different holes, improving installation accuracy. In precision machinery with high installation accuracy requirements, this fine-tuning function is crucial to ensure the normal operation and performance of the equipment.

[0031] In this example, the irregular groove can accommodate the end of the bolt, preventing the bolt end from being loosened by collision, thus protecting the bolt.

[0032] In this embodiment, the bearing body and the flange are further configured to have the same axis, and the bearing body and the flange are integrally formed.

[0033] In this embodiment, the graphite pillars are further configured to correspond one-to-one with the cylindrical holes, and the size and number of the graphite pillars are consistent with those of the cylindrical holes.

[0034] In this embodiment, the distance between the centers of adjacent cylindrical holes is further set to 45 degrees.

[0035] In this embodiment, the end of the irregular groove away from the bearing body is an arc, and the end of the irregular groove near the bearing body is a semicircle. The axis of the semicircle is consistent with the axis of the bolt hole, and the diameter of the semicircle is larger than the diameter of the bolt hole.

[0036] In this embodiment, the distance between the axes of adjacent bolt holes is further set to 20 degrees.

[0037] In this embodiment, the bolt holes are further configured to be through holes, and the depth of the irregular groove is less than half the thickness of the flange, thereby ensuring the basic structural strength of the flange.

[0038] In this embodiment, the bearing body is further provided with a chamfer 6 on the inner side of the end away from the flange. The chamfering process can remove the burrs and sharp edges in the original position and facilitate the installation of the shaft.

[0039] In this embodiment, it is further configured that there are marking blocks 7 on both sides of the flange. The installation angle can be calculated through the marking blocks. This design is an anti-misalignment design. Irregular grooves and bolt holes can also be opened at the marking blocks to improve versatility and interchangeability.

[0040] In this example, the bearing body and the flange are made of copper alloy. Copper alloy has corrosion resistance and good thermal conductivity, making it suitable for high-speed and high-temperature working environments.

[0041] Example 2:

[0042] In this embodiment, as Figure 6 As shown, the present invention proposes a multi-hole flanged bearing, comprising a bearing body and a flange 2. The inner wall of the bearing body is provided with a circumferential array of cylindrical holes, each of which is inlaid with a graphite column. The side of the flange away from the bearing body is provided with a circumferential array of irregular grooves 4, and the side of the flange close to the bearing body is provided with a circumferential array of bolt holes 5. The bolt holes pass through the irregular grooves, and the bolt holes correspond one-to-one with the irregular grooves. The bolt holes are provided with internal threads. The bolts pass through the bolt holes to connect the flange to the corresponding holes of external mechanical parts, thereby fixing the bearing body.

[0043] In this embodiment, the end of the irregular groove away from the bearing body is an arc, and the end of the irregular groove near the bearing body is a semicircle. The axis of the semicircle is consistent with the axis of the bolt hole, and the diameter of the semicircle is larger than the diameter of the bolt hole.

[0044] In this embodiment, the distance between the axes of adjacent bolt holes is further set to 30 degrees. In another example, the distance between the axes of adjacent bolt holes can also be 45 degrees.

[0045] In this example, the variation in the spacing between the axes of adjacent bolt holes can meet more installation requirements.

[0046] In this embodiment, it is further configured that there are identification blocks 7 on both sides of the flange.
