Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically to a segmented bearing cage. Background Technology

[0002] A bearing cage, also known as a bearing retainer, is a bearing component that partially encloses all or part of the rolling elements and moves with them. It is used to isolate the rolling elements. The cage is an important component used to isolate the rolling elements inside the bearing. Its function is to guide the rolling elements to move normally during bearing operation and to keep the rolling elements from leaving the bearing at any time.

[0003] Cages are usually a one-piece structure. After the cage is installed in the bearing, if one or more pockets of the cage are damaged due to friction and collision during use, the entire cage needs to be replaced. Damaged cages are not easy to repair and can only be scrapped, resulting in significant losses. Utility Model Content

[0004] In view of the deficiencies of the prior art, the present invention provides a segmented bearing cage, which includes multiple individual cage modules. Each individual cage module can be processed individually. Each individual cage module provides a pocket. Adjacent individual cage modules can be easily assembled and disassembled. When a single pocket is damaged, it can be replaced or scrapped individually to reduce losses.

[0005] To achieve the above objectives, the present invention provides a segmented bearing cage, comprising multiple individual cage modules, a first end cap, and a second end cap. Each individual cage module includes a first beam and a second beam, with a pocket between the first and second beams for accommodating a portion of the cylindrical rollers. A protrusion is provided on the side of the first beam away from the pocket, and a recess is provided on the side of the second beam away from the pocket. The protrusion of one individual cage module mates with the recess of an adjacent individual cage module. A first cage end is provided between one end of the first beam and one end of the second beam, and a second cage end is provided between the other ends of the first and second beams. A first through hole is provided at the first cage end, and a second through hole is provided at the second cage end. Multiple first protrusions are provided on one side of the first end cap, with an interference fit between the first protrusions and the openings of the first through holes away from the pockets. Multiple second protrusions are provided on one side of the second end cap, with an interference fit between the second protrusions and the openings of the second through holes away from the pockets.

[0006] Furthermore, the opening diameter of the first through hole on the side closer to the pocket is smaller than the opening diameter of the first through hole on the side farther from the pocket.

[0007] Furthermore, the opening diameter of the second through hole on the side closer to the pocket is smaller than the opening diameter of the second through hole on the side farther from the pocket.

[0008] Furthermore, the first protrusion has a first oil hole, one end of which is connected to the first through hole, and the other end of which extends to the end face of the first end cap.

[0009] Furthermore, the second protrusion has a second oil hole, one end of which is connected to the second through hole, and the other end of which extends to the end face of the second end cap.

[0010] Furthermore, the convex portion has two concave first mating arc surfaces on both sides.

[0011] Furthermore, the concave portion has two protruding second mating arc surfaces on both sides, which mate with the first mating arc surface.

[0012] Furthermore, the protrusion is disposed on the side surface of the first beam column and is disposed along the axial direction of the retainer.

[0013] Furthermore, the recess is provided on the side surface of the second beam and is arranged along the axial direction of the cage.

[0014] The beneficial effects of this utility model are as follows: It includes multiple individual cage modules, which can be processed and transported independently and can be modularly stocked, which is more convenient. The protrusion of one individual cage module can be inserted into the recess of another individual cage module along the axial direction, which is convenient for assembly and disassembly. When a single pocket position is damaged due to friction and impact with the cylindrical roller, affecting the normal operation of the bearing, the damaged individual cage module can be disassembled separately and replaced with a new individual cage module, which can save costs.

[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] See Figure 1 , Figure 2 and Figure 5 The diagram shows a structural schematic of a segmented bearing cage according to an embodiment of the present invention, which includes multiple individual cage modules 100, a first end cap 200 and a second end cap 300; after the multiple individual cage modules 100 are sequentially inserted along the axial direction of the cage, a first end cap 200 is installed at one end and a second end cap 300 is installed at the other end.

[0018] See Figures 1-3 Each individual retainer module 100 includes a first beam 110 and a second beam 120. A first retainer end 140 is provided between one end of the first beam 110 and one end of the second beam 120, and a second retainer end 150 is provided between the other end of the first beam 110 and the other end of the second beam 120. The first beam 110, the second beam 120, the first retainer end 140, and the second retainer end 150 together form a pocket 130. Specifically, as... Figure 2 As shown, a pocket 130 is provided between the first beam column 110 and the second beam column 120. The pocket 130 is used to accommodate part of the cylindrical roller 10. A protrusion 111 is provided on the side of the first beam column 110 away from the pocket 130, and a recess 121 is provided on the side of the second beam column 120 away from the pocket 130. The protrusion 111 of one unit retainer module 100 cooperates with the recess 121 of the adjacent unit retainer module 100. During assembly, the protrusion 111 of one unit retainer module 100 can be inserted into the recess 121 of another unit retainer module 100 along the axial direction.

[0019] like Figure 1 , Figure 3 and Figure 5 As shown, the first retainer end 140 has a first through hole 141, and the second retainer end 150 has a second through hole 151. A plurality of first protrusions 210 are provided on one side of the first end cap 200, and the first protrusions 210 are interference-fitted with the opening of the first through hole 141 on the side away from the pocket 130. A plurality of second protrusions 310 are provided on one side of the second end cap 300, and the second protrusions 310 are interference-fitted with the opening of the second through hole 151 on the side away from the pocket 130. During assembly, the multiple individual retainer modules 100 are first assembled into one unit, and then the multiple individual retainer modules 100 are locked together using the first end cap 200 and the second end cap 300.

[0020] The aforementioned segmented bearing cage includes multiple individual cage modules 100. Each individual cage module 100 can be independently manufactured and modularly stocked, making it convenient to transport even before assembly, requiring minimal transport space. Furthermore, the protrusion 111 of one individual cage module 100 can be axially inserted into the recess 121 of another individual cage module 100, facilitating assembly and disassembly. When a single pocket position is damaged due to friction and impact with the cylindrical rollers, affecting the normal operation of the bearing, the damaged individual cage module 100 can be disassembled individually and replaced with a new one, saving costs.

[0021] like Figure 5 As shown, in one embodiment, the opening diameter of the first through hole 141 near the pocket 130 is smaller than the opening diameter of the first through hole 141 away from the pocket 130. Similarly, in one embodiment, the opening diameter of the second through hole 151 near the pocket 130 is smaller than the opening diameter of the second through hole 151 away from the pocket 130. This facilitates the insertion of the first protrusion 210 into the first through hole 141 and the insertion of the second protrusion 310 into the second through hole 151.

[0022] See Figures 5-7In one embodiment, the first protrusion 210 has a first oil hole 211. One end of the first oil hole 211 is connected to the first through hole 141, and the other end of the first oil hole 211 extends to the end face of the first end cover 200. Lubricating oil and / or grease are added to the bearing through the first oil hole 211 and the first through hole 141. During the operation of the bearing, the lubricating oil and grease inside are thrown onto the inner wall of the first through hole 141 by centrifugal force and enter the bearing along the inner wall of the first through hole 141, thus playing a good lubricating role.

[0023] See Figures 5-7 In one embodiment, the second protrusion 310 has a second oil hole 311. One end of the second oil hole 311 is connected to the second through hole 151, and the other end of the second oil hole 311 extends to the end face of the second end cover 300. Lubricating oil and / or grease are added to the bearing through the second oil hole 311 and the second through hole 151. During the operation of the bearing, the lubricating oil and grease inside are thrown onto the inner wall of the second through hole 151 by centrifugal force, and then enter the bearing along the inner wall of the first through hole 141, thus providing good lubrication.

[0024] like Figure 2 As shown, in one embodiment, the convex portion 111 has two concave first mating arc surfaces 1111 on both sides. In another embodiment, the concave portion 121 has two protruding second mating arc surfaces 1211 on both sides, and the second mating arc surfaces 1211 mate with the first mating arc surfaces 1111.

[0025] In one embodiment, a protrusion 111 is provided on the side surface of the first beam 110 and is arranged along the axial direction of the cage. In another embodiment, a recess 121 is provided on the side surface of the second beam 120 and is arranged along the axial direction of the cage. This arrangement facilitates the insertion of the protrusion 111 into the recess 121 along the axial direction to establish a connection between adjacent individual cage modules 100.
