All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4, the present utility model provides a technical solution: a bearing that is easy to disassemble, including an outer housing 1, an inner housing 2 is sleeved inside the outer housing 1, fixing grooves 1 are opened at both the top and bottom of the outer housing 1, a mating hole is opened on the surface of the fixing groove 1, and the fixing groove 1 is fixedly connected through the mating hole with a bolt, and the fixing plate 1 is fixedly connected with the outer housing 1 through the bolt. A limiting groove 1 is opened on the inner wall of the outer housing 1, the fixing groove 1 and the fixing groove 2 are located corresponding to each other, the limiting groove 1 and the limiting groove 2 are located corresponding to each other, the inside of the limiting groove 1 is engaged with the outer side of the upper cage 10, a fixing plate 1 is arranged inside the fixing groove 1, a plurality of fixing holes 6 are opened on the surface of the fixing plate 1, and the fixing holes 6 are evenly distributed in a circumferential array on the surface of the fixing plate 1. A fixing groove 2 is opened on the upper surface of the inner housing 2, a fixing plate 2 is arranged inside the fixing groove 2, a plurality of fixing holes 6 are opened on the side surface of the fixing plate 2, and the fixing plate 2 is fixed on the surface of the fixing groove 2 through the fixing holes 6 and bolts. A limiting groove 2 is opened on the inner wall of the inner housing 2, an upper cage 10 is arranged on the side surface of the outer housing 1, the bottom of the upper cage 10 is fixedly welded with a clamping block 11, the side surface of the clamping block 11 is fixedly welded with a clamping block 12, a clamping groove 13 is opened on the upper surface of the upper cage 10, a connecting hole 14 is opened on the surface of the upper cage 10, steel balls 15 are arranged inside the upper cage 10, and a lower cage 16 is arranged at the bottom of the steel balls 15.

[0020] Fixing grooves 1 are opened on both the top surface and the bottom surface of the outer housing 1, a mating hole is opened on the surface of the fixing groove 1, and the fixing groove 1 is fixedly connected with the fixing plate 1 through a bolt and the fixing hole 6. The limiting groove 1 is engaged with the outer side of the upper cage 10, and the limiting groove 2 is engaged with the inner side of the upper cage 10. The upper cage 10 is limited inside the limiting groove 1 and the limiting groove 2 through the fixing plate 1 and the fixing hole 6, so as to prevent the positions of the upper cage 10 and the lower cage 16 from shifting during the use of the bearing. The upper cage 10 and the lower cage 16 are limited through the limiting groove 1 and the limiting groove 2. At the same time, due to the existence of the limiting groove 1 and the limiting groove 2, the rotation of the upper cage 10 is smoother, and it is easier to cooperate with lubricating oil for lubrication, and to prevent impurities from entering between the outer housing 1 and the inner housing 2 and affecting the normal rotation of the steel balls 15. The upper cage 10 is an arc-shaped plate, the number of the upper cages 10 is several, and the upper cages 10 are evenly distributed in a circumferential array around the center of the inner housing 2. A clamping groove is opened at the bottom of the clamping block 11, and the steel balls 15 are attached to the inner wall of the clamping groove. Both the clamping block 12 and the clamping groove 13 are T-shaped, and the clamping block 12 and the clamping groove 13 are respectively located at both ends of the upper cage 10, and the clamping groove 13 and the clamping block 12 are movably inserted. The connecting hole 14 penetrates through the upper cage 10 and then extends into the inner part of the lower cage 16, and the lower cage 16 is fixedly connected with the upper cage 10 through a bolt and the connecting hole 14. By removing the bolt in the connecting hole 14 and then pulling out the clamping block 12 from the corresponding upper cage 10, the upper cage 10 and the lower cage 16 can be separated, so as to facilitate the maintenance and replacement of the steel balls 15.

[0021] Working principle: When disassembling, the staff removes the bolts on the fixing plate 1-5 and the fixing holes 6, takes out the fixing plate 1-5 from the inside of the fixing groove 1-3, and takes out the fixing plate 2-8 from the fixing groove 2-7. Then, the upper cage 10 and the lower cage 16 can be taken out as a whole from between the outer housing 1 and the inner housing 2, effectively reducing the difficulty of disassembling the upper cage 10. When it is necessary to replace the damaged steel balls 15, the bolts in the connection holes 14 are taken out, and then the clamping blocks 12 are pulled out from the corresponding upper cage 10, so that the upper cage 10 can be separated from the lower cage 16, facilitating the repair and replacement of the steel balls 15. During installation, the clamping blocks 12 are inserted into the clamping grooves 13 of the adjacent upper cage 10 on one side to connect and fix several upper cages 10. The upper cage 10 and the lower cage 16 are connected and fixed through the connection holes 14. Then, the upper cage 10 is placed on the surfaces of the limiting groove 1-4 and the limiting groove 2-9 at the same time, and the fixing plate 1-5 is fixed in the fixing groove 1-3 with bolts, and the fixing plate 2-8 is fixed in the fixing groove 2-7, thus completing the installation.
