[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] See also Figures 1 to 4 , which is the first embodiment of the utility model, and the embodiment provides a technical solution: a bearing that is easy to assemble, comprising an outer ring 1, an inner ring 2, balls 4 and a quick-installed cage structure, wherein a plurality of balls 4 are rollingly installed between the outer ring 1 and the inner ring 2, and the quick-installed cage structure comprises a front cage 3 and a rear cage 5 installed together one after the other, and the surfaces of the front cage 3 and the rear cage 5 are integrally provided with an arc-shaped sleeve 7, and the arc-shaped sleeve 7 is sleeved on the surface of the balls 4. Under the limiting action of the arc-shaped sleeve 7 on the two cages, the plurality of balls 4 in the bearing can be evenly distributed, and will not gather at one end, thereby ensuring the installation stability of the bearing, and an assembly structure 6 is provided between the front cage 3 and the rear cage 5;

[0020] The assembly structure 6 includes a cylindrical plug rod 61, an L-shaped movable block 62, a circular socket 63, a triangular block 64 and an annular groove 65. A plurality of cylindrical plug rods 61 are welded and fixed on the front surface of the rear retainer 5. A circular socket 63 corresponding to the cylindrical plug rod 61 is provided on the surface of the front retainer 3. The front end of the cylindrical plug rod 61 passes through the circular socket 63 to the front surface of the front retainer 3. Two L-shaped movable blocks 62 are movably installed at each circular socket 63 on the front surface of the front retainer 3. A triangular block 64 is welded and fixed on the inner surface of the L-shaped movable block 62. An annular groove 65 corresponding to the triangular block 64 is provided on the front end surface of the cylindrical plug rod 61. The two L-shaped movable blocks 62 are respectively attached to the two sides of the cylindrical plug rod 61, and the triangular block 64 By being embedded in the annular groove 65, the cylindrical insertion rod 61 can be effectively limited, and the assembly of the front retainer 3 and the rear retainer 5 can be quickly realized. The assembly structure 6 also includes a movable structure, which is arranged between the L-shaped movable block 62 and the front retainer 3. The movable structure includes an inner slide groove 66, an inner slider 67 and a spring 68. The inner slide groove 66 is opened on the front surface of the front retainer 3, and the position corresponds to the L-shaped movable block 62. The inner slider 67 is movably installed in the inner slide groove 66 by the spring 68, and one end of the inner slider 67 extends to the front surface of the front retainer 3 and is fixed together with the L-shaped movable block 62. Under the pushing action of the spring 68, the triangular block 64 can be stably stuck in the annular groove 65 during daily use, thereby ensuring the assembly stability of the front retainer 3 and the rear retainer 5.

[0021] Among them, a guide slide rod 69 is also fixed to one side surface of the inner sliding block 67, and a slide rod groove 610 corresponding to the guide slide rod 69 is penetrated through the inner wall of one end of the inner sliding groove 66, and one end of the guide slide rod 69 is slidably located in the slide rod groove 610. The guide slide rod 69 can guide and limit the spring 68 to prevent the spring 68 and the inner sliding block 67 from sliding out of the inner sliding groove 66.

[0022] The end of the slide bar groove 610 is in communication with the circumferential surface of the front retaining frame 3 .

[0023] In summary, when assembling the actual bearing, first place the inner ring 2 on the inner side of the outer ring 1, and then fit the inner ring 2 and the outer ring 1 on one side, so that the distance between the inner ring 2 and the other side of the outer ring 1 becomes larger. At this time, multiple balls 4 can be inserted between the outer ring 1 and the inner ring 2 from this position, and then the position of the inner ring 2 is adjusted and rotated, so that the balls 4 are evenly distributed between the outer ring 1 and the inner ring 2, and the inner ring 2 is concentric with the outer ring 1. At this time, the quick-install cage structure is assembled. During assembly, it is only necessary to push the front cage 3 and the rear cage 5 between the outer ring 1 and the inner ring 2 one after the other, and put the arc-shaped ferrule 7 on the ball 4, so that the cylindrical The insertion rod 61 is inserted into the circular hole 63 and passes through the front surface of the front retaining frame 3. At this time, the front end of the cylindrical insertion rod 61 will squeeze the triangular block 64, causing the L-shaped movable block 62 and the triangular block 64 to move sideways, and causing the inner slider 67 to move sideways to compress the spring 68 until the front retaining frame 3 and the rear retaining frame 5 are successfully fitted. At this time, the triangular block 64 will be aligned with the annular groove 65, and under the push of the spring 68, the L-shaped movable block 62 and the triangular block 64 rebound and reset, so that the triangular block 64 is stuck in the annular groove 65, and the assembly of the quick-install retaining frame structure can be completed quickly, realizing the rapid assembly of the bearing.

[0024] Example 2

[0025] See also Figures 1 to 5 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the open end of the slide bar groove 610 can be effectively blocked by the provided sealing structure.

[0026] Specifically, the assembly structure 6 also includes a sealing structure, which is arranged on the circumferential surface of the front retainer 3. The sealing structure includes a plurality of sealing pads 611 installed on the circumferential surface of the front retainer 3. One end of the sealing pad 611 extends to the opening of the slide bar groove 610 to seal it. The end surface of the sealing pad 611 is also provided with a sealing insert 612 embedded in the inner side of the slide bar groove 610, which can effectively seal the opening of the slide bar groove 610 to prevent the accidental entry of foreign matter from the outside. An integrated L-shaped rubber seat 613 is provided on the other end surface. The sealing gasket 611, the sealing insert 612 and the L-shaped rubber seat 613 are all made of fluororubber and will undergo elastic deformation when squeezed. An L-shaped mounting groove 614 corresponding to the L-shaped rubber seat 613 is provided on the circumferential surface of the front retaining frame 3. The L-shaped rubber seat 613 is inserted into the L-shaped mounting groove 614 for stable installation of the sealing gasket 611, thereby ensuring stable sealing of the sliding bar groove 610 by the sealing gasket 611 and the sealing insert 612.

[0027] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
