Description

Technical Field

[0001] The utility model relates to the technical field of retaining frames, in particular to a retaining frame assembly. Background Art

[0002] Cage, also known as bearing cage, refers to a bearing part that partially wraps all or part of the rolling elements and moves with them to isolate the rolling elements and usually guide the rolling elements and keep them in the bearing.

[0003] For example, a bearing retainer with the authorization announcement number CN216478470U has the advantages of good structural stability and wear resistance. However, during the use of the retainer assembly in the above document, the upper frame body and the lower frame body are connected by bolts. This connection method uses a large number of bolts, and each bolt needs to be tightened with the help of a tool of corresponding size when fixing the upper frame body and the lower frame body. At the same time, each bolt is rotated a large number of times, so the installation operation of the upper frame body and the lower frame body is relatively cumbersome;

[0004] At the same time, during the use of the retainer assembly in the above document, the contact surface between the inside of the retainer and the balls in the bearing cannot be replaced. After the retainer assembly isolates the balls inside, the degree of wear between the balls and the retainer assembly is different during use. Therefore, when replacing the retainer assembly, the retainer as a whole needs to be replaced, thereby increasing the cost of replacing the retainer. Utility Model Content

[0005] The utility model aims to solve the problem that the installation operation of the upper frame and the lower frame is complicated and the cost of replacing the entire retainer is high when replacing the retainer assembly, and proposes a retainer assembly.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A retainer assembly is designed, including an upper retainer and a lower retainer, the bottom end of the upper retainer is fitted with the lower retainer, and a connecting structure is provided at the bottom of the upper retainer, and the connecting structure includes an insert block, the top ends of multiple insert blocks are fixedly connected to multiple upper retainers, the two sides of the insert block are clamped with multiple clamping blocks, the outer end of the clamping block is fixedly connected to a moving block, and the outer end of the moving block is fixedly connected to one end of a first spring.

[0010] Preferably, the middle portion of the upper retaining frame and the middle portion of the lower retaining frame are respectively fitted with a plurality of support blocks, and the bottom ends of the support blocks are fixedly connected to the contact blocks.

[0011] Preferably, an auxiliary structure is provided in the middle of the support block, and the auxiliary structure includes a second spring, one end of the second spring is fixedly connected to the support block, the other end of the second spring is fixedly connected to the vertical rod, both sides of the vertical rod are respectively fixedly connected to the round blocks on both sides, the outer wall of the round block is slidably connected to the connecting block, and the top end of the vertical rod is rotatably connected to the rotating block.

[0012] Preferably, the middle parts of the outer walls of the connecting blocks on both sides are slidably connected to the supporting blocks, the outer sides of the outer walls of the connecting blocks on the top are fitted with the upper retaining frame, and the outer sides of the outer walls of the connecting blocks on the top are fitted with the lower retaining frame.

[0013] The utility model provides a cage assembly, which has the beneficial effect that: after the lower cage is connected to the ball bearing and the balls inside the ball bearing are sequentially isolated, the upper cage is then connected to the cage through the insert block, so that when the insert block is inserted into the through hole of the lower cage, the insert block squeezes the blocks on both sides to move outward, the clamping block drives the moving block to move outward, the moving block drives the first spring to compress, and when the groove of the insert block corresponds to the clamping block, the elastic force of the first spring drives the clamping block to clamp with the insert block, thereby realizing the connection between the upper cage and the lower cage, and replacing the original fixing method in this way makes the installation of the upper cage and the lower cage more convenient;

[0014] Pull the rotating block, the rotating block drives the vertical rod to move outward, the vertical rod drives the second spring to stretch, and at the same time rotates the rotating block through ninety degrees, so that the rotating block is blocked by the support block and cannot move inward, the vertical rod drives the round block to move outward, and the round block drives the connecting blocks on both sides to move inward, and then the contact surface is inserted into the corresponding upper retaining frame or lower retaining frame through the support block, and then the rotating block is rotated forty-five degrees, so that the rotating block is affected by the elastic force of the second spring to make the connecting block move outward and connect with the upper retaining frame, thereby fixing the contact block. Similarly, multiple contact blocks are connected to the upper retaining frame and the lower retaining frame in turn. In this way, the contact blocks with more severe wear can be replaced without replacing the entire retaining frame, thereby reducing the cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings: Example 1

[0022] Refer to the attached Figure 1-4 In this embodiment, a cage assembly includes an upper cage 1 and a lower cage 2. The bottom end of the upper cage 1 is fitted with the lower cage 2. A connecting structure 3 is provided at the bottom of the upper cage 1. The connecting structure 3 includes an insert block 301. The top ends of the multiple insert blocks 301 are fixedly connected to the multiple upper cages 1. The two sides of the insert block 301 are clamped with the multiple clamping blocks 304. After the lower cage 2 is connected to the ball bearing and the balls inside the ball bearing are isolated in turn, the upper cage 1 is then connected to the cage 2 through the insert block 301. When the insert block 301 is inserted into the through hole of the lower holder 2, the insert block 301 squeezes the blocks 304 on both sides to move outward, the clamping block 304 drives the moving block 302 to move outward, and the moving block 302 drives the first spring 303 to compress. When the groove of the insert block 301 corresponds to the clamping block 304, the elastic force of the first spring 303 drives the clamping block 304 to clamp with the insert block 301, thereby realizing the connection between the upper holder 1 and the lower holder 2. This method replaces the original fixing method, making the installation of the upper holder and the lower holder more convenient.

[0023] The outer end of the clamping block 304 is fixedly connected to the moving block 302, the outer end of the moving block 302 is fixedly connected to one end of the first spring 303, the outer wall of the clamping block 304 is slidably connected to the lower retaining frame 2, the top of the moving block 302 is slidably connected to the lower retaining frame 2, the outer wall of the inserting block 301 is fitted with the lower retaining frame 2, the other end of the first spring 303 is fixedly connected to the lower retaining frame 2, the middle part of the upper retaining frame 1 and the middle part of the lower retaining frame 2 are respectively fitted with multiple support blocks 6, and the bottom end of the support block 6 is fixedly connected to the contact block 5.

[0024] An auxiliary structure 4 is provided in the middle of the support block 6. The auxiliary structure 4 includes a second spring 4a5. One end of the second spring 4a5 is fixedly connected to the support block 6. The other end of the second spring 4a5 is fixedly connected to the vertical rod 4a2. Both sides of the vertical rod 4a2 are fixedly connected to the round blocks 4a4 on both sides respectively. The outer wall of the round block 4a4 is slidably connected to the connecting block 4a3. The top of the vertical rod 4a2 is rotatably connected to the rotating block 4a1. The rotating block 4a1 is square. When the rotating block 4a1 is pulled, the rotating block 4a1 drives the vertical rod 4a2 to move outward, and the vertical rod 4a2 drives the second spring 4a5 to stretch. At the same time, the rotating block 4a1 is rotated by ninety degrees, so that the rotating block 4a1 is blocked by the support block 6 and cannot move inward.

[0025] The vertical rod 4a2 drives the round block 4a4 to move outward, and the round block 4a4 drives the connecting blocks 4a3 on both sides to move inward, and then the contact surface 5 is inserted into the corresponding upper retaining frame 1 or the lower retaining frame 2 through the supporting block 6, and then the rotating block 4a1 is rotated forty-five degrees, so that the rotating block 4a1 is affected by the elastic force of the second spring 4a5 to make the connecting block 4a3 move outward and connect with the upper retaining frame 1, so as to fix the contact block 5, and the middle part of the outer wall of the connecting blocks 4a3 on both sides of the second spring 4a5 is slidably connected with the supporting block 6, and the outer side of the outer wall of the top connecting block 4a3 is in contact with the upper retaining frame 1, and the outer side of the outer wall of the top connecting block 4a3 is in contact with the lower retaining frame 2.

[0026] Working principle:

[0027] Pull the rotating block 4a1, the rotating block 4a1 drives the vertical rod 4a2 to move outward, the vertical rod 4a2 drives the second spring 4a5 to stretch, and at the same time rotates the rotating block 4a1, rotates it ninety degrees, so that the rotating block 4a1 is blocked by the support block 6 and cannot move inward, the vertical rod 4a2 drives the round block 4a4 to move outward, and the round block 4a4 drives the connecting blocks 4a3 on both sides to move inward, and then the contact surface 5 is inserted into the corresponding upper retaining frame 1 or the lower retaining frame 2 through the support block 6, and then the rotating block 4a1 is rotated forty-five degrees, so that the rotating block 4a1 is affected by the elastic force of the second spring 4a5, so that the connecting block 4a3 moves outward and connects with the upper retaining frame 1, thereby fixing the contact block 5. Similarly, multiple contact blocks 5 are connected to the upper retaining frame 1 and the lower retaining frame 2 in turn. In this way, the contact block 5 with more serious wear can be replaced without replacing the retaining frame as a whole, thereby reducing the cost;

[0028] Subsequently, the lower retainer 2 is connected to the ball bearing and the balls inside the ball bearing are isolated in turn, and then the upper retainer 1 is connected to the retainer 2 through the plug block 301, so that when the plug block 301 is inserted into the through hole of the lower retainer 2, the plug block 301 squeezes the blocks 304 on both sides to move outward, the clamping block 304 drives the moving block 302 to move outward, and the moving block 302 drives the first spring 303 to compress. When the groove of the plug block 301 corresponds to the clamping block 304, the elastic force of the first spring 303 drives the clamping block 304 to clamp with the plug block 301, thereby realizing the connection between the upper retainer 1 and the lower retainer 2. In this way, the original fixing method is replaced, making the installation of the upper retainer and the lower retainer more convenient, thereby completing the installation of the bearing. Example 2

[0029] Refer to the attached Figure 1-4 In this embodiment, a retainer assembly is provided, wherein the auxiliary structure 4 may further include a square block 4b1. The end of the square block 4b1 is fixedly connected to the support block 6, and the outer wall of the square block 4b1 is slidably connected to the rotating block 4a1. The rotating block 4a1 is pulled upward and then rotated 180 degrees. The rotating block 4a1 is released, and the rotating block 4a1 is restricted by the square block 4b1 so that the rotating block 4a1 cannot be reset, thereby avoiding the need for the staff to continuously apply external force to the rotating block 4a1, making the installation and removal of the support block 6 more convenient.
