[0026] In the specific implementation process, as shown in Figures 1-3 , it includes a hub mechanism 1 and an outer bearing ring 3 installed on a bicycle. A bearing steel bowl 2 is provided on the hub mechanism 1. A plurality of key grooves 4 are axially formed inside the bearing steel bowl 2. A number of load-bearing keys 5 are fixedly spaced on the outer wall of the outer bearing ring 3. The load-bearing keys 5 are matched with the key grooves 4 in size. An oil injection hole 6 is penetrated through the load-bearing key 5. An oil injection pipe 7 is communicatively provided on the bearing steel bowl 2. The oil injection pipe 7 and the oil injection hole 6 are in the same plane. When injecting oil, it is not necessary to disassemble the bearing. Only need to open the plug at the oil injection pipe 7 and then use a syringe to inject lubricating oil at the oil injection pipe 7.
[0027] Two half-ring seats 8 are symmetrically fixed on the outer bearing ring 3. A sliding column 9 is penetrated through the half-ring seat 8. The sliding column 9 is slidably connected with the half-ring seat 8. A pulling plate 10 is fixed on the sliding column 9. Pulling the pulling plate 10 can drive the sliding column 9 to move.
[0028] Two limit seats 11 are symmetrically fixed on the bearing steel bowl 2. A limit groove 12 is formed in the limit seat 11. The sliding column 9 extends into the limit groove 12, and the sliding column 9 is matched with the limit groove 12 in size. A spring 13 is sleeved on the sliding column 9. One end of the spring 13 is fixed on the pulling plate 10, and the other end of the spring 13 is fixed on the half-ring seat 8. During installation, the staff only needs to move the two pulling plates 10, then place the outer bearing ring 3 into the bearing steel bowl 2 along the direction of the key groove 4, and finally release the two pulling plates 10. Under the action of the spring 13, the sliding column 9 will enter the limit groove 12, and at this time, the fixing work of the bearing can be completed. The operation is simple and convenient. By setting the load-bearing key 5 and the key groove 4, the bearing can be prevented from moving during use, greatly improving its anti-offset and load-bearing capacity and extending its service life.
[0029] There is a bearing inner ring 14 inside the bearing outer ring 3. A number of balls 15 are arranged between the bearing outer ring 3 and the bearing inner ring 14.

A number of card posts 20 are circumferentially fixed on the ring-shaped retaining ring 16. The card posts 20 are fitted with the card slots 19. By arranging the ring-shaped retaining ring 16 and the wear-resistant rubber pad 17, leakage of the lubricating oil inside the bearing can be avoided. When the wear-resistant sealing pad 17 needs to be replaced, it is not necessary to replace the whole bearing, and only the corresponding ring-shaped retaining ring 16 needs to be replaced, which reduces the cost.
[0030] The working principle of the present utility model: During installation, the staff only needs to move two pull plates 10, and then place the bearing outer ring 3 into the bearing steel bowl 2 along the direction of the keyway 4.
