[0002] Tapered roller bearings are separable bearings. Both the inner and outer rings of the bearings have tapered raceways. Tapered roller bearings can withstand axial loads in one direction and limit the axial displacement of the shaft or housing in one direction.

[0030] Reference Figure 1-4 As shown, in this embodiment: a plurality of protruding rods 22 are fixedly connected to the upper and lower ends of the reinforcement ring 21, and the side of the protruding rod 22 away from the reinforcement ring 21 is fixedly connected to the top of the inner wall of the retaining ring 6. By setting the protruding rod 22, the connection between the inner wall of the reinforcement ring 21 and the retaining ring 6 can be further reinforced to avoid displacement of the reinforcement ring 21 as much as possible and increase the stability of the structure. A plurality of rectangular rods 23 are fixedly connected to the upper and lower ends of the reinforcement ring 21, and the two ends of the rectangular rod 23 are fixedly connected to the side where the two protruding rods 22 are close to each other. By setting the rectangular rod 23, the position between the two protruding rods 22 on the inner wall of the retaining ring 6 can be reinforced, and the top of the roller body 5 is in contact with the outer surface of the protruding rod 22 when the inner wall of the reinforcement ring 21 rotates, so that it is not easy to shake.
[0031] Reference Figure 1-4 As shown, in this embodiment: the top and bottom ends of the outer surface of the retaining ring 6 are respectively fixedly connected with outer rings 26, and the outer ring 26 protrudes from the top and bottom parts of the retaining ring 6. By arranging the outer ring 26, the top and bottom edges of the retaining ring 6 can be protected to increase the wear resistance of the retaining ring 6. The inner wall of the reinforcement ring 21 is provided with an annular groove 24, and the upper and lower sides of the inner wall of the annular groove 24 are respectively fixedly connected with convex strips 25. By arranging the annular groove 24 and the convex strips 25, the lubricating oil entering the annular oil groove 7 can be retained in the annular groove 24 as much as possible and seep out slowly to improve the lubrication time of the roller body 5.
[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment: the outer surface of the retaining ring 6 is provided with a sealing structure 3, the sealing structure 3 includes a sealing strip 32, and the two ends of the sealing strip 32 are respectively fixedly connected with clamping blocks 31. After adding lubricating oil into the through hole 8 at the annular oil groove 7, the sealing strip 32 can be attached to the inner wall of the annular oil groove 7, and the two clamping blocks 31 are respectively clamped in the inside of the two through holes 8 so that the sealing strip 32 is attached to the annular oil groove 7, and the inside of the annular oil groove 7 is sealed to avoid leakage of lubricating oil as much as possible to prolong the lubrication effect.
