[0003] In the prior art, the connection between the inner ring of the bearing and the hub and the connection between the outer ring of the bearing and the steering knuckle usually adopt press-in interference fit to realize the close connection between the inner ring and the hub and the outer ring and the steering knuckle. However, such connection mode has high requirements on the manufacturing precision of the inner ring and the outer ring, and when the bearing needs to be replaced subsequently, it is cumbersome to disassemble, time-consuming and laborious. Therefore, a hub bearing convenient to disassemble is urgently needed to improve the disassembly convenience of the inner ring and the hub and the outer ring and the steering knuckle. SUMMARY

[0004] In order to improve the disassembly convenience of the hub bearing, the present application provides a hub bearing and a bearing assembly device.

[0005] In the first aspect, the hub bearing provided by the present application adopts the following technical scheme:

[0007] By adopting the above technical scheme, the combination of the first rolling ball and the second rolling ball can improve the overall load capacity of the hub bearing and enhance the overall structural stability; the first flange plate is arranged on the outer peripheral wall of the bearing seat, the second flange plate is arranged on the outer peripheral wall of the outer ring, during installation, the first flange plate is connected to the hub by a bolt in sequence, and the second flange plate is connected to the steering knuckle, thereby improving the disassembly convenience of the inner ring and the hub and the outer ring and the steering knuckle. Moreover, the first connecting hole and the second connecting hole are arranged in a staggered manner to provide a clearance space for the respective bolt connection, so as to facilitate the disassembly of the bolt and further improve the disassembly convenience of the overall structure.

[0008] In a second aspect, the bearing assembling device comprises the following technical solutions:

[0009] The bearing assembling device for assembling the hub bearing comprises an assembling table and a pushing assembly. An upper surface of the assembling table is provided with an assembling station for mounting the inner ring and the outer ring. A positioning protrusion for sleeving the inner ring is arranged on the assembling station. An outer diameter of the positioning protrusion is matched with an inner diameter of the inner ring. The pushing assembly is arranged on the assembling table and located at one side of the positioning protrusion for pushing the outer ring.

[0010] By adopting the above technical solutions, when the inner ring and the outer ring are mounted, the inner ring is sleeved on the outer periphery of the positioning protrusion to fix the inner ring. Then, the outer ring is sleeved on the outer periphery of the inner ring. When the outer ring is mounted, the inner periphery wall of the outer ring is forced to abut against the outer periphery wall of the inner ring, so that a larger space is reserved between the inner ring and the outer ring for embedding the first rolling balls. Then, after the first rolling balls are sequentially put into the first rolling ring channel, the pushing assembly is used to apply a certain pushing force to the outer ring to force the outer ring to displace relative to the inner ring, so that the outer ring and the inner ring can be concentric to embed the first rolling balls in the first rolling ring channel.

[0011] Optionally, the assembling table is provided with a mounting seat. The pushing assembly comprises a pushing rod, a rotating rod, a pushing cam and a driving rod. The pushing rod is slidably installed on the mounting seat. An end of the pushing rod close to the positioning protrusion is provided with a pushing head. The rotating rod is rotatably connected to the mounting seat and located at a side of the pushing rod away from the positioning protrusion. The pushing cam is arranged on the outer periphery wall of the rotating rod for pushing the pushing rod. A first spring is arranged between the pushing rod and the mounting seat. Under normal circumstances, the first spring forces the pushing rod to slide away from the positioning protrusion. One end of the driving rod is connected to the rotating rod.

[0012] By adopting the above technical solutions, after the first rolling balls are put into the first rolling ring channel, the driving rod is used to force the rotating rod to rotate, so that the outer periphery wall of the pushing cam can push the pushing rod, force the pushing rod to slide towards the side close to the positioning protrusion, and make the pushing head of the pushing rod push the outer ring, so that the outer ring is displaced to be concentric with the inner ring, thereby embedding the first rolling balls in the first rolling ring channel.

[0013] Optionally, a limiting protrusion is arranged on the assembling station and located at a side of the positioning protrusion away from the pushing rod. When the outer ring is sleeved on the outer periphery of the inner ring and abuts against the limiting protrusion, the inner periphery wall of the outer ring abuts against the outer periphery wall of the inner ring, and the center of the outer ring is located at a side of the center of the inner ring close to the pushing rod. The limiting protrusion is slidably installed on the assembling table. The assembling table is provided with a lifting assembly for driving the limiting protrusion to lift.

[0014] By adopting the technical scheme, the limiting protrusion is arranged to provide positioning effect for the installation of the outer ring, when the outer ring is installed, the outer ring is sleeved on the outer circumferential side of the inner ring, and the outer circumferential wall of the outer ring is forced to abut against the limiting protrusion close to the side wall of the inner ring, so that the inner circumferential wall of the outer ring is forced to abut against the outer circumferential wall of the inner ring, and the center of the outer ring is located on the center of the inner ring close to the side of the push rod, so that the first rolling ball is conveniently put in, and the push rod can subsequently accurately push the outer ring, and the operation convenience of the overall structure is improved.

[0015] Optionally, the upper surface of the assembly table is provided with a lifting groove, and the limiting protrusion is slidably installed in the lifting groove; the lifting assembly comprises a pull rope and a second spring, one end of the pull rope is connected to the limiting protrusion, and the other end of the pull rope is connected to the rotating rod; the second spring is arranged between the limiting protrusion and the assembly table, and in a normal state, the second spring forces the limiting protrusion to be lifted out of the upper surface of the assembly table; when the driving rod is driven to rotate, the rotating rod forces the limiting protrusion to sink into the lifting groove through the pull rope; and when the limiting protrusion sinks into the lifting groove and the driving rod continues to rotate, the push rod pushes the outer ring.

[0016] By adopting the technical scheme, when the outer ring is sleeved on the outer circumferential side of the inner ring and the inner circumferential wall of the outer ring abuts against the outer circumferential wall of the inner ring, pulling the driving rod forces the rotating rod to rotate, the rotating rod can pull the limiting protrusion through the pull rope, so that the limiting protrusion sinks into the lifting groove, so that the push rod can subsequently push the outer ring. When the driving rod drives the limiting protrusion to sink into the lifting groove, continue to drive the driving rod to rotate, so that the rotating rod continues to rotate, at this time, the rotating rod can push the push rod through the push cam, so as to push the outer ring, force the inner ring and the outer ring to be concentric, and improve the operation convenience of the overall structure.

[0017] Optionally, the bottom of the assembly table is provided with an isolator, when the plurality of first rolling balls are embedded in the first rolling ring and the inner ring and the outer ring are forced to be concentric, the isolator is used to force the plurality of first rolling balls to be arranged at intervals around the central axis of the inner ring; the isolator comprises a first pushing assembly and a second pushing assembly which act in sequence; the first pushing assembly is used to force the plurality of first rolling balls to abut against each other to position the plurality of first rolling balls; when the plurality of first rolling balls abut against each other, the second pushing assembly is used to force the plurality of first rolling balls to be spaced apart in sequence.

[0018] By adopting the technical scheme, the outer ring is pushed to form concentricity between the inner ring and the outer ring, and then the first pushing assembly is used to force the plurality of first rolling balls to abut against each other to determine the positions of the plurality of first rolling balls in the first rolling ring channel. After the plurality of first rolling balls abut against each other under the action of the first pushing assembly, the second pushing assembly is used to sequentially isolate the plurality of first rolling balls, and the plurality of first rolling balls are spaced apart, which facilitates the subsequent installation of the bearing retainer. Before the second pushing assembly is actuated, the first pushing assembly is used to determine the positions of the plurality of first rolling balls, so that the second pushing assembly can accurately isolate the plurality of first rolling balls one by one, and the operation convenience of the overall structure is greatly improved.

[0019] Optionally, the surface of the assembly table is provided with a through groove, the through groove is communicated with the first rolling ring channel when the inner ring and the outer ring outside the positioning protrusion maintain concentricity, the through groove is arranged in an arc shape around the central axis of the positioning protrusion, and the two ends of the through groove form a first point and a second point, respectively. The first pushing assembly comprises a first lifting seat, a fixed strip, a movable strip, and a guide piece. The first lifting seat is slidingly installed at the bottom of the assembly table.

One end of the movable strip is slidingly installed at the first lifting seat, and the other end extends into the through groove and can slide along the arc of the through groove. The guide piece is arranged between the first lifting seat and the movable strip. In a normal state, the guide piece forces the fixed strip and the movable strip to abut against each other, and the fixed strip and the movable strip are located at the first point of the through groove. When the first lifting seat is lifted and forces the fixed strip and the movable strip to be inserted into the first rolling ring channel, the guide piece forces the movable strip to slide to the second point. When the movable strip slides to the second point, the fixed strip and the movable strip jointly clamp the plurality of first rolling balls to force the plurality of first rolling balls to abut against each other.

[0020] By adopting the technical scheme, in a normal state (when the fixed strip and the movable strip are not inserted into the first rolling ring channel), the fixed strip and the movable strip are located at the first point of the through groove. After the inner ring and the outer ring form concentricity, the first lifting seat is lifted to simultaneously insert the upper end of the fixed strip and the upper end of the movable strip into the first rolling ring channel from the first point. After the movable strip is inserted into the first rolling ring channel, the movable strip can slide to the second point along the through groove under the action of the guide piece, so as to push the first rolling balls in the first rolling ring channel to force all the first rolling balls to abut against each other, which facilitates the subsequent second pushing assembly to accurately isolate the plurality of first rolling balls, and improves the operation convenience of the overall structure.

[0022] By adopting the technical scheme, in a normal state (when the fixed strip and the movable strip are not inserted into the first rolling ring channel), the guide column is located in the second guide part, so that the fixed strip and the movable strip can abut against each other, and the fixed strip and the movable strip are forced to be located at the first point of the through groove. After the first lifting seat is forced to lift and drive the fixed strip and the movable strip to be inserted into the first rolling ring channel, the guide column is driven to move into the first guide part under the action of the movable strip, at this time, the third spring restores the deformation, so as to force the movable strip to slide to the second point of the through groove (during the sliding process of the movable strip, the guide column slides in the first guide part), and then force all the first rolling balls to abut against each other, thereby improving the operation convenience of the overall structure.

[0023] Optionally, the second pushing assembly comprises a second lifting seat and a squeezing strip, the second lifting seat is slidably installed at the bottom of the assembly table, the squeezing strip is vertically arranged, the lower end of the squeezing strip is connected to the second lifting seat, a plurality of the squeezing strips are arranged at intervals around the central axis of the positioning protrusion, and an isolation gap for accommodating a single first rolling ball is formed between adjacent two squeezing strips; when the movable strip slides to the second point, a positioning area is formed between the fixed strip and the movable strip, and a plurality of first rolling balls abut against each other in the positioning area; the upper end faces of the squeezing strips are arranged to be different in height, and the upper end faces of the plurality of squeezing strips gradually decrease in height from one side of the fixed strip close to the positioning area to the other side of the fixed strip away from the positioning area.

With the continuous lifting of the second lifting seat, the plurality of extrusion strips are sequentially inserted into the first rolling ring track, so that the plurality of first rolling balls are sequentially separated, and the plurality of first rolling balls can be uniformly and spacedly distributed around the central axis of the positioning protrusion, so that the subsequent installation of the bearing retainer is facilitated, and the operation convenience of the overall structure is greatly improved.

[0025] Optionally, the top wall of the second lifting seat is provided with a plurality of sliding grooves, the plurality of sliding grooves are correspondingly arranged with the plurality of extrusion strips, the lower end of each extrusion strip is slidably arranged in the corresponding sliding groove, and the extrusion strip is slidably arranged in the second lifting seat through the sliding groove.

When the outer ring is installed, the outer ring is sleeved on the outer circumferential side of the inner ring, and the outer circumferential wall of the outer ring is forced to abut against the limiting protrusion close to the side wall of the inner ring, so that the inner circumferential wall of the outer ring can be forced to abut against the outer circumferential wall of the inner ring, and the center of the outer ring is located on the side close to the push rod. Such design not only facilitates the placement of the first rolling ball, but also facilitates the subsequent precise pushing of the outer ring by the push rod, thereby improving the operation convenience of the overall structure.

[0030] 3. The outer ring is pushed by the first pushing assembly and the second pushing assembly to form concentricity between the inner ring and the outer ring.

The plurality of first rolling balls are spaced apart, which facilitates the subsequent installation of the bearing retainer. Before the second pushing assembly acts, the first pushing assembly is used to determine the position of the plurality of first rolling balls, so that the second pushing assembly can accurately isolate the plurality of first rolling balls one by one, thereby greatly improving the operation convenience of the overall structure.

[0056] Embodiment 3: The embodiment of the application discloses a bearing assembly device.

[0057] The bearing assembly device disclosed by the embodiment of the application is different from the embodiment 2 in that:

[0058] Reference Figure 5 ,Figure 6 In the embodiment, the upper surface of the assembly table 4 is provided with a lifting groove 45, which is located on the side of the positioning protrusion 42 away from the push rod 51. The lifting groove 45 is provided with a limiting protrusion 44. The side wall of the limiting protrusion 44 close to the positioning protrusion 42 forms a limiting arc surface 441. The limiting arc surface 441 is used to abut the outer peripheral wall of the outer ring 3. When the outer ring 3 is sleeved on the outer peripheral side of the inner ring 2, and the outer peripheral wall of the outer ring 3 abuts the limiting arc surface 441 of the limiting protrusion 44, the inner peripheral wall of the outer ring 3 abuts the outer peripheral wall of the inner ring 2, and the center of the outer ring 3 is located on the center of the inner ring 2 close to the push rod 51.

[0059] In the embodiment, the limiting protrusion 44 is slidingly installed in the lifting groove 45 of the assembly table 4. The assembly table 4 is provided with a lifting assembly 6 for driving the limiting protrusion 44 to lift. The lifting assembly 6 includes a pull rope 61 and a second spring 62. One end of the pull rope 61 is connected to the lower end surface of the limiting protrusion 44, and the other end of the pull rope 61 passes through the assembly table 4 and is fixedly connected to the push cam 53 of the rotating rod 52.

When the driving rod 54 is driven to rotate, the rotating rod 52 forces the limiting protrusion 44 to sink into the lifting groove 45 through the pull rope 61. When the limiting protrusion 44 sinks into the lifting groove 45 and the driving rod 54 continues to rotate, the push rod 51 pushes the outer ring 3 (i.e., after the limiting protrusion 44 sinks into the lifting groove 45, the rotating rod 52 continues to rotate, and at this time, the outer peripheral wall of the push cam 53 pushes the push rod 51).

[0060] The implementation principle of the embodiment 3 of the application is that the limiting protrusion 44 is provided to provide positioning effect for the installation of the outer ring 3. When the outer ring 3 is installed, the outer ring 3 is sleeved on the outer peripheral side of the inner ring 2, and the outer peripheral wall of the outer ring 3 is forced to abut the side wall of the limiting protrusion 44 close to the inner ring 2. Thus, the inner peripheral wall of the outer ring 3 can be forced to abut the outer peripheral wall of the inner ring 2, and the center of the outer ring 3 is located on the center of the inner ring 2 close to the push rod 51. Such design not only facilitates the placement of the first rolling ball 32, but also facilitates the subsequent precise pushing of the push rod 51 to the outer ring 3, thereby improving the operation convenience of the overall structure.

[0061] After the outer ring 3 is sleeved on the outer circumferential side of the inner ring 2 and the inner circumferential wall of the outer ring 3 abuts against the outer circumferential wall of the inner ring 2, the driving rod 54 is pulled to force the rotating rod 52 to rotate, the rotating rod 52 can pull the limiting block 44 through the pull rope 61, so that the limiting block 44 is forced to sink into the lifting groove 45, so that the subsequent push rod 51 can push the outer ring 3. After the driving rod 54 drives the limiting block 44 to sink into the lifting groove 45, the driving rod 54 is continuously driven to rotate, so that the rotating rod 52 continues to rotate, and at this time the rotating rod 52 can push the push rod 51 through the push cam 53 to push the outer ring 3, so that the inner ring 2 and the outer ring 3 are kept concentric, and the operation convenience of the overall structure is improved.

[0062] Embodiment 4: The embodiment of the application discloses a bearing assembling device.

[0064] With reference to Figure 7 , Figure 8 In the embodiment, the bottom of the assembling table 4 is provided with an isolator, which is used to force the plurality of first rolling balls 32 to be arranged at intervals around the central axis of the inner ring 2 when the plurality of first rolling balls 32 are embedded in the first rolling ring channel 31 and the inner ring 2 and the outer ring 3 are kept concentric.

[0065] The isolator comprises a first pushing assembly 7 and a second pushing assembly 8 which act in sequence; the first pushing assembly 7 is used to force the plurality of first rolling balls 32 to abut against each other to position the plurality of first rolling balls 32; and the second pushing assembly 8 is used to force the plurality of first rolling balls 32 to be arranged at intervals in sequence when the plurality of first rolling balls 32 abut against each other.

[0066] With reference to Figure 9 , Figure 10 , Figure 11 The surface of the assembling table 4 is provided with a through groove 46 which is arranged in an arc shape around the central axis of the positioning block 42, and the through groove 46 is communicated with the first rolling ring channel 31 when the inner ring 2 and the outer ring 3 on the outer side of the positioning block 42 are kept concentric; for the convenience of description, one end of the through groove 46 is defined as a first point 461 and the other end is defined as a second point 462.

[0067] With reference to Figure 7 , Figure 8The first pushing assembly 7 comprises a first lifting seat 71, a fixed strip 72, a movable strip 73 and a guide piece. The bottom of the assembly table 4 is connected with a plurality of first guide rods 48. The first guide rods 48 are vertically arranged. The upper end of the first guide rods 48 is fixedly connected to the lower surface of the assembly table 4. The lower end of the first guide rods 48 is slidably connected to the first lifting seat 71. The first lifting seat 71 is slidably installed on the bottom of the assembly table 4 by the plurality of first guide rods 48, so as to be capable of lifting. In the embodiment, the first lifting seat 71 is in an arc shape. The virtual central axis of the first lifting seat 71 is arranged in coincidence with the central axis of the positioning protrusion 42.

[0068] With reference to Figure 7 , Figure 8 , Figure 9 The fixed strip 72 and the movable strip 73 are vertically arranged. The lower end of the fixed strip 72 is fixedly connected to the inner arc surface of the first lifting seat 71. The upper end of the fixed strip 72 extends to the first point 461 of the through groove 46. The inner arc surface of the first lifting seat 71 is provided with a moving groove 711. The two ends of the moving groove 711 extend along the arc of the first lifting seat 71. The lower end of the movable strip 73 is slidably installed in the moving groove 711. The upper end of the movable strip 73 extends to the through groove 46, so as to be capable of sliding along the arc of the through groove 46.

[0069] With reference to Figure 7 , Figure 8 , Figure 10 The guide piece is arranged between the first lifting seat 71 and the movable strip 73. Under normal circumstances, the guide piece forces the fixed strip 72 and the movable strip 73 to be in close contact with each other. The fixed strip 72 and the movable strip 73 are located at the first point 461 of the through groove 46. When the first lifting seat 71 is lifted and forces the upper end of the fixed strip 72 and the upper end of the movable strip 73 to be inserted into the first rolling ring channel 31, the guide piece forces the movable strip 73 to slide to the second point 462. When the movable strip 73 slides to the second point 462, the fixed strip 72 and the movable strip 73 jointly clamp the plurality of first rolling balls 32, so as to force the plurality of first rolling balls 32 to abut against each other.

[0070] With reference to Figure 8 , Figure 12In the embodiment, the guide member includes a guide column 74 and a third spring. The inner wall of the through groove 46 is provided with a guide groove 47. One end of the guide column 74 is fixedly connected to the side wall of the movable strip 73, and the other end extends into the guide groove 47. The guide groove 47 includes a first guide portion 471 and a second guide portion 472. The first guide portion 471 extends along the arc of the through groove 46. One end of the second guide portion 472 is connected to one end of the first guide portion 471. The first guide portion 471 and the second guide portion 472 combine to form an "L shape". When the movable strip 73 extends into the first rolling ring channel 31, the guide column 74 moves into the first guide portion 471. When the movable strip 73 moves downward out of the first rolling ring channel 31, the guide column 74 moves into the second guide portion 472.

[0071] A third spring (not shown in the figure) is installed in the moving groove 711 of the first lifting seat 71. The third spring is arc-shaped. One end of the third spring is fixedly connected to the inner wall of the moving groove 711, and the other end is fixedly connected to the lower end of the movable strip 73. When the guide column 74 moves into the first guide portion 471, the third spring forces the movable strip 73 to slide from the first point 461 of the through groove 46 to the second point 462 of the through groove 46.

[0072] Referring to Figure 7 , Figure 11 , Figure 13 The second pushing assembly 8 includes a second lifting seat 81 and a squeezing pushing strip 82. The bottom of the assembly table 4 is connected with a plurality of second guide rods 49. The second guide rods 49 are vertically arranged.

The second lifting seat 81 is slidably installed on the bottom of the assembly table 4 through the plurality of second guide rods 49 to be able to lift.

[0073] The squeezing pushing strip 82 is vertically arranged. The lower end of the squeezing pushing strip 82 is connected to the second lifting seat 81. The squeezing pushing strip 82 is spaced apart around the central axis of the positioning boss 42. The spacing between the adjacent two squeezing pushing strips 82 forms an isolation gap 83 for accommodating a single first rolling ball 32. When the movable strip 73 slides to the second point 462, a positioning area 311 is formed between the fixed strip 72 and the movable strip 73. The plurality of first rolling balls 32 abut against each other in the positioning area 311. The upper end faces of the plurality of squeezing pushing strips 82 are arranged at different heights. The heights of the upper end faces of the plurality of squeezing pushing strips 82 gradually decrease from the side of the fixed strip 72 close to the positioning area 311 to the side of the fixed strip 72 away from the positioning area 311. A plurality of avoiding grooves are formed on the surface of the assembly table 4 for the squeezing pushing strips 82 to extend out.

[0074] Referring to Figure 13The top wall of the second lifting seat 81 is provided with a plurality of sliding grooves 811, and the plurality of sliding grooves 811 are correspondingly arranged with the plurality of extrusion strips 82. The lower end of each extrusion strip 82 is slidably arranged in the corresponding sliding groove 811, and the extrusion strip 82 is slidably arranged in the second lifting seat 81 through the sliding groove 811. The fourth spring 84 is arranged between each extrusion strip 82 and the second lifting seat 81. One end of the fourth spring 84 is fixedly connected to the second lifting seat 81, and the other end is fixedly connected to the extrusion strip 82.

[0075] It should be noted that in the embodiment, the second lifting seat 81 is annular, the central axis of the second lifting seat 81 is arranged to coincide with the central axis of the positioning protrusion 42, the second lifting seat 81 is located directly below the first rolling ring channel 31, the first lifting seat 71 is located above the second lifting seat 81, and the inner diameter of the inner arc surface of the first lifting seat 71 is not less than the outer diameter of the second lifting seat 81. The first lifting seat 71 and the second lifting seat 81 can be driven by a cylinder (the driving source of the first lifting seat 71 and the driving source of the second lifting seat 81 are not embodied in the embodiment).

[0076] The implementation principle of the embodiment 4 of the application is that after the plurality of first rolling balls 32 are embedded in the first rolling ring channel 31 and forced to form concentric between the inner ring 2 and the outer ring 3, first, the first lifting seat 71 is driven to lift, the fixed strip 72 and the movable strip 73 are inserted into the first rolling ring channel 31 from the first point position 461 of the through groove 46, after the movable strip 73 is inserted into the first rolling ring channel 31, the guide column 74 is moved into the first guide part 471 under the driving of the movable strip 73, at this time, the third spring restores the deformation, thereby forcing the movable strip 73 to slide to the second point position 462 of the through groove 46, so that the movable strip 73 can push the first rolling ball 32 in the first rolling ring channel 31, and force all the first rolling balls 32 to abut each other, so as to determine the position of the plurality of first rolling balls 32 in the first rolling ring channel 31.

[0077] After the plurality of first rolling balls 32 in the first rolling ring channel 31 abut each other, the second lifting seat 81 is driven to lift, the extrusion strip 82 with the highest upper end surface height is forced to be inserted into the first rolling ring channel 31 first, and is inserted between the two adjacent first rolling balls 32, so as to separate the two adjacent first rolling balls 32, the second lifting seat 81 is continuously lifted, the extrusion strip 82 with the second highest upper end surface height is inserted into the first rolling ring channel 31, and is inserted between the corresponding two adjacent first rolling balls 32, so as to separate the corresponding two adjacent first rolling balls 32. With the continuous lifting of the second lifting seat 81, the plurality of extrusion strips 82 are sequentially inserted into the first rolling ring channel 31, thereby sequentially separating the plurality of first rolling balls 32, so that the plurality of first rolling balls 32 can be uniformly and spacedly distributed around the central axis of the positioning protrusion 42, so as to facilitate the subsequent installation of the bearing retainer, and greatly improve the operation convenience of the overall structure.

[0078] During the process of sequentially inserting the plurality of pushing strips 82 into the first rolling ring channel 31, the movable strip 73 is gradually displaced by the pushing force back to the fixed strip 72 until the plurality of pushing strips 82 are all inserted into the first rolling ring channel 31, and then the movable strip 73 can be displaced back to abut against the fixed strip 72, so that after the plurality of first rolling balls 32 are uniformly spaced apart, the fixed strip 72, the movable strip 73 and the pushing strips 82 can be removed, thereby facilitating subsequent workers to install the retainer, and improving the operation convenience of the overall structure.

[0079] The above is the preferred embodiment of the present application, which does not limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
