Abstract
Description
Technical Field
[0001] This application relates to the field of bearing housing technology, and specifically to a sealed bearing housing. Background Technology
[0002] A bearing is a mechanical component that limits relative motion within a desired range of motion and reduces friction between moving parts. The function of a bearing is to limit the movement of a shaft and eliminate vibration during shaft rotation. Bearings require a bearing housing for fixation and installation during use.
[0003] In existing technology centers, bearing housings are typically added to the outside of the bearing to fix its position and provide external support.
[0004] However, bearing housings typically lack sealing features, making it easy for external dust and other contaminants to enter the bearing. This leads to contamination of the bearing lubricating oil, reduces the bearing's lifespan, and increases maintenance costs in case of bearing failure. Utility Model Content
[0005] To address the problems mentioned in the background art and improve bearing service life while reducing maintenance costs, this application provides a sealed bearing housing. The bearing housing includes a housing body for mounting the bearing and multiple end caps. The end caps are mounted at both ends of the housing body and each end cap includes a first base and a first plate, which are fixedly connected. The end caps are inserted into both ends of the housing body to seal both ends of the bearing. A second plate, square in shape, is connected to the side of the housing body and is used to fix the housing body.
[0006] With this design, a hole is provided at the center of the end of the bearing housing, into which a bearing is installed. End caps are installed at both ends of the hole. A first base on one side of the end cap is inserted into the hole in the bearing housing. The middle of the first base also has a hole for the passage of components such as rods fitted inside the bearing. The addition of the end caps reduces the gap between the end of the bearing housing and the components inside the bearing, decreasing the possibility of external impurities falling into the bearing. A second plate is located on the side of the bearing housing and engages with an external fixing rod. The groove structure on the second plate allows the bearing housing to slide relative to the fixing rod, enabling the bearing housing to be installed in multiple positions for easy installation by the operator.
[0007] According to one embodiment of this application, the first base is cylindrical and extends in the length direction of the seat body, and the length of the first base is greater than 13mm and the wall thickness is not less than 5mm.
[0008] With this configuration, the first base extends towards the interior of the seat and its length must be greater than 13mm. If the length is too small, the end of the first base cannot abut against the bearing, and the bearing cannot be fixed by clamping the bearing with end caps at both ends. The wall thickness must be no less than 5mm. Since a rotatable rod is usually installed inside the bearing, the gap between the rod and the inner wall of the first base is also a place that needs to be strictly regulated. If the wall thickness is too small, it is easy for the gap between the rod and the first base to be too large. This not only makes it easy for external impurities to fall into the bearing, but also makes it easy for the rod to lose support, causing the rod to deflect and produce abnormal noise when rotating.
[0009] According to one embodiment of this application, a hole is provided at the end of the seat body for installing a bearing. The first base body passes through the hole and is connected to the bearing to change the bearing fixing method.
[0010] This configuration, by setting end caps at both ends of the seat, allows the first base at one end of the end cap to clamp the front and rear ends of the bearing, thus preventing the bearing from deflecting when the internal rod rotates. This changes the original bearing fixing method, and the bearing is more convenient to install and disassemble in this way.
[0011] According to one embodiment of this application, at least four first through holes are provided on the first plate, and a plurality of second through holes are provided at the end of the base body corresponding to the first through holes.
[0012] With this design, when it is necessary to remove the end cover, only the bolts in the first through holes on the end cover at both ends need to be removed to remove the end cover. Compared with traditional bearing housings, where the fixing bolts are all located on the base below, after all the bolts are removed, the bearing housing is easily disconnected from the fixing plate, which can easily cause the bearing to lose the support of the bearing housing and lead to a dangerous situation.
[0013] According to one embodiment provided in this application, the diameter of the first through hole is at least greater than 4.8 mm.
[0014] With this configuration, the first and second through holes are used to place M6*16 bolts. If the hole diameter is too small, the bolts used will also be smaller. Since part of the support force of the rod inside the bearing is provided by the first base, using bolts that are too small can easily lead to insufficient tightness in the connection between the end cover and the seat. When the bearing is working and rotating, it can easily cause the connection between the seat and the end cover to loosen or cause the bolts inside to break.
[0015] According to one embodiment of this application, the inner diameter of the first substrate is not less than 34 mm and the outer diameter is not less than 40 mm.
[0016] With this configuration, the first base is cylindrical, with its inner wall supporting the rod inside the bearing and its outer wall fitting against the inner wall of the seat. If the inner wall of the first base is too small, the rod may not be able to rotate smoothly. If the outer wall of the first base is too small, the connection between the first base and the seat may not fit properly, preventing them from forming an integrated structure. This can cause collisions between the first base and the seat, reducing the product's lifespan and increasing maintenance costs.
[0017] According to one embodiment of this application, the first plate includes arc-shaped plates disposed on both sides, the outer diameter of the arc-shaped plates not exceeding 60mm, and the thickness of the first plate not exceeding 6mm.
[0018] With this design, the two sides of the first plate are curved plates with an outer diameter not exceeding 60mm. The purpose is to fit the shape of the seat body to enhance the connection and tightness between the first plate and the seat body.
[0019] The thickness of the first plate should not exceed 6mm. If the thickness of the first plate is too large, the length of the bolt inside the seat will be too short. The rotation of the rod inside the bearing will cause some vibration. If the length of the bolt inside the seat is insufficient, the bolt may come off the seat, causing the connection between the end cover and the seat to loosen.
[0020] According to one embodiment of this application, a groove is provided in the middle of the second plate, and the groove extends from one end of the second plate along its length to the other end.
[0021] The sealed bearing housing provided in this application includes a housing body for mounting the bearing and multiple end caps. The end caps are installed at both ends of the housing body and include a first base and a first plate, which are fixedly connected. The end caps are inserted into both ends of the housing body to seal both ends of the bearing. A hole is provided at the center of the end of the housing body, in which the bearing is installed. End caps are installed at both the front and rear ends of the hole. A first base on one side of the end cap is inserted into the hole of the housing body. A hole is also provided in the middle of the first base for passing through components such as rods fitted inside the bearing. By adding the end cap as a connecting component, the gap between the end of the housing body and the components installed inside the bearing is reduced, thus reducing the possibility of external impurities falling into the bearing.

[0035] A bearing is a mechanical component that limits relative motion within a desired range of motion and reduces friction between moving parts. The function of a bearing is to limit the movement of a shaft and eliminate vibration during shaft rotation. Bearings require a bearing housing for fixation and installation during use.
[0036] In existing technology centers, bearing housings are typically added to the outside of the bearing to fix its position and provide external support.
[0037] However, bearing housings typically lack sealing features, making it easy for external dust and other contaminants to enter the bearing. This leads to contamination of the bearing lubricating oil, reduces the bearing's lifespan, and increases maintenance costs in case of bearing failure.
[0038] Figure 1 This is a schematic diagram of the structure of a sealed bearing housing provided in an embodiment of this application. Figure 2 This is a structural schematic diagram from another perspective of a sealed bearing housing provided in an embodiment of this application. Figure 3 For the appendix Figure 1 Front view, Figure 4 For the appendix Figure 1 A bottom view.
[0039] See attached document Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, in order to solve the problems mentioned in the background art, improve the service life of bearings and reduce maintenance costs, this application provides a sealed bearing housing. The bearing housing includes a housing body 100 for mounting bearings and a plurality of end caps 200. The end caps 200 are mounted at both ends of the housing body 100. Each end cap 200 includes a first base and a first plate 210. The first plate 210 and the first base are fixedly connected. The end caps 200 are inserted into both ends of the housing body 100 to seal both ends of the bearing.
[0040] It should be noted that a hole is provided at the center of the end of the seat body 100, and a bearing is installed in the hole. End caps 200 are installed at both the front and rear ends of the hole. A first base on one side of the end cap 200 is inserted into the hole of the seat body 100. A hole is also provided in the middle of the first base for the rod and other components sleeved in the bearing to pass through. The addition of the end cap 200 as a connecting component reduces the gap between the end of the seat body 100 and the components installed in the bearing, reducing the possibility of external impurities falling into the bearing.
[0041] According to one embodiment of this application, the first base is cylindrical and extends toward the length of the base 100, and the length of the first base is at least greater than 13mm and the wall thickness is at least not less than 5mm.
[0042] It should be noted that the first base extends into the seat 100 and its length must be greater than 13mm. If the length is too small, the end of the first base cannot abut against the bearing, and the bearing cannot be fixed by clamping the bearing with the end caps 200 at both ends. The wall thickness must be no less than 5mm. Since a rotatable rod is usually set inside the bearing, the gap between the rod and the inner wall of the first base is also a place that needs to be strictly regulated. If the wall thickness is too small, it is easy for the gap between the rod and the first base to be too large. This not only makes it easy for external impurities to fall into the bearing, but also makes it easy for the rod to lose support, causing the rod to deflect and produce abnormal noise when it rotates.
[0043] It is worth mentioning that the rod and the first base should be fitted with a transition fit, which can improve the sealing and reduce the occurrence of deflection when the rod rotates.
[0044] According to one embodiment of this application, a hole is provided at the end of the base 100 for installing a bearing. The first base passes through the hole and is connected to the bearing to change the bearing fixing method.
[0045] It should be noted that the existing bearing housing fixing method on the market usually involves installing a fixing ring on the outer sleeve of the bearing, with a threaded hole at the bottom of the fixing ring for fixing in one place. This application, by setting end caps 200 at both ends of the housing 100, allows the first base at one end of the end cap 200 to clamp the front and rear ends of the bearing, so as to prevent the bearing from deflecting when the internal rod rotates. This changes the original bearing fixing method, and fixing the bearing in this way makes installation and disassembly more convenient.
[0046] According to one embodiment of this application, at least four first through holes 221 are provided on the first plate 210, and a plurality of second through holes are provided at the end of the base 100 corresponding to the first through holes 221.
[0047] It should be noted that when it is necessary to disassemble the end cover 200, only the bolts provided in the first through hole 221 on the end cover 200 at both ends need to be removed to remove the end cover 200. Compared with the traditional bearing housing, the fixing bolts of the traditional bearing housing are all located on the base below. After all the bolts are removed, the bearing housing is disconnected from the fixing plate, which may cause the bearing to lose the support of the bearing housing and lead to a dangerous situation.
[0048] According to one embodiment provided in this application, the diameter of the first through hole 221 is at least greater than 4.8 mm.
[0049] It should be noted that the first through hole 221 and the second through hole are used to place M6*16 bolts. If the hole diameter is too small, the bolts used will also be smaller. Since part of the support force of the rod set inside the bearing is provided by the first base, using bolts that are too small can easily lead to insufficient tightness in the connection between the end cover 200 and the seat 100. When the bearing is working and rotating, it can easily cause the connection between the seat 100 and the end cover 200 to loosen or cause the bolts set inside to break.
[0050] According to one embodiment of this application, the inner diameter of the first substrate is not less than 34 mm and the outer diameter is not less than 40 mm.
[0051] It should be noted that the first base is cylindrical, with its inner wall supporting the rod inside the bearing and its outer wall fitting against the inner wall of the seat 100. If the inner wall of the first base is too small, the rod may not be able to rotate smoothly. If the outer wall of the first base is too small, the connection between the first base and the seat 100 may not fit properly, preventing the first base and the seat 100 from forming an integral structure. This can cause collisions between the first base and the seat 100, reducing the product's lifespan and increasing maintenance costs.
[0052] According to one embodiment of this application, the first plate 210 includes arc-shaped plates disposed on both sides, the outer diameter of the arc-shaped plates not exceeding 60mm, and the thickness of the first plate 210 not exceeding 6mm.
[0053] It should be noted that the two sides of the first plate 210 are curved plates with an outer diameter of no more than 60mm. The purpose of this is to fit the shape of the seat 100 and enhance the connection and tightness between the first plate 210 and the seat 100.
[0054] In addition, it should be noted that the thickness of the first plate 210 does not exceed 6mm. If the thickness of the first plate 210 is too large, the length of the bolt inside the seat 100 will be too short. The rotation of the rod inside the bearing will cause some vibration. If the length of the bolt inside the seat 100 is insufficient, the bolt may easily come off the seat 100, causing the connection between the end cover 200 and the seat 100 to loosen.
[0055] According to one embodiment of this application, a second plate 110 is connected to the side of the seat 100. The second plate 110 is square and is used to fix the seat 100.
[0056] It should be noted that the second plate 110 is located on the side of the base 100. The second plate 110 is engaged with the external fixing rod. The groove structure of the second plate 110 allows the bearing seat to slide relative to the fixing rod, so that the bearing seat can be installed in multiple positions, which is convenient for operators to install.
[0057] According to one embodiment of this application, a groove 111 is provided in the middle of the second plate 110, and the groove 111 extends from one end of the second plate 110 along its length to the other end.
[0058] It should be noted that the second plate 110 is provided with a through groove 111, and the groove 111 is an inverted trapezoid when viewed from the front, which makes it easy for the operator to install the bearing seat on the fixing rod.
[0059] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this application are indicated by the following claims.
