[0028] Example 1: Please refer to Figures 1-6 Existing wear-resistant deep groove ball bearings are not easy to prevent excessive wear during long-term use. In order to solve this technical problem, this embodiment discloses the following technical content;

[0029] The right side of the left outer ring 1 is connected to the right outer ring 3, and the inner sides of the left outer ring 1 and the right outer ring 3 are connected to the left inner ring 8 and the right inner ring 9. The inner ends of the left outer ring 1, the right outer ring 3, the left inner ring 8 and the right inner ring 9 are provided with connecting mechanisms. The connecting mechanisms are composed of connecting grooves 2, connecting plates 4 and fixing bolts 6. The inner sides of both ends of the left outer ring 1 and the left inner ring 8 are provided with connecting grooves 2. The inner sides of both ends of the right outer ring 3 and the right inner ring 9 are fixedly connected with connecting plates 4. The connecting plates 4 are engaged with the connecting grooves 2 and fixedly connected by the fixing bolts 6.

[0030] Arc-shaped grooves 7 are provided on the inner middle of the left outer ring 1 and the right outer ring 3, and on the outer middle of the left inner ring 8 and the right inner ring 9. Ball bearings 10 are slidably connected in the arc-shaped grooves 7. Several ball bearings 10 are slidably connected in the arc-shaped grooves 7 on the inner sides of the left outer ring 1, the right outer ring 3, the left inner ring 8 and the right inner ring 9. First storage slots 5 are provided on the upper and lower ends of the inner sides of the left outer ring 1 and the right outer ring 3, and on the upper and lower ends of the outer sides of the left inner ring 8 and the right inner ring 9. An outer cover plate 11 and an inner cover plate 13 are respectively connected in the first storage slots 5. The outer end of the outer cover plate 11 is fixedly connected to the left outer ring 1 and the right outer ring 3 by several bolts. The connecting ring 14 on the outer middle of the inner cover plate 13 is slidably connected to the second storage slot 12 on the inner middle of the outer cover plate 11. The inner end of the inner cover plate 13 is fixedly connected to the left inner ring 8 and the right inner ring 9 by several bolts.

[0031] A lubrication mechanism 15 is provided on the inner side of the rear end of the left outer ring 1. The lubrication mechanism 15 is composed of an oil groove 1501, an oil inlet 1502, a plug 1503, a sealing ring 1504, and a sponge block 1505. The top middle of the oil groove 1501 is connected to the oil inlet 1502. The top inner side of the oil inlet 1502 is threaded with a plug 1503. The lower top surface of the plug 1503 is fixedly connected with a sealing ring 1504. The inner middle of the oil groove 1501 is fixedly connected with a sponge block 1505. The outer side of the sponge block 1505 is in contact with the outer side of the ball 10.

[0032] When using a deep groove ball bearing, place the balls 10 into the left outer ring 1 and the left inner ring 8, and also place the balls 10 between the right outer ring 3 and the right inner ring 9. The balls 10 are located in the arc groove 7. After the balls 10 are installed, engage the connecting groove 2 and connecting plate 4 on the left outer ring 1 and the left inner ring 8 with the right outer ring 3 and the right inner ring 9. Fix the left outer ring 1 and the right outer ring 3 with the left inner ring 8 and the right inner ring 9 with the stabilizing bolts 6. The left outer ring 1, the right outer ring 3, the left inner ring 8, the right inner ring 9 and the balls 10 together form the body of the deep groove ball bearing.

[0033] Then, the outer cover plate 11 and the inner cover plate 13 are put together and placed in the first storage slot 5 opened at the upper and lower ends of the outer ring and the inner ring. Then, the outer end of the outer cover plate 11 and the inner end of the inner cover plate 13 are fixedly connected to the outer ring and the inner ring respectively with bolts.

The outer cover plate 11 and the inner cover plate 13 are connected to the outer ring and the inner ring, which does not affect the rotation of the outer ring and the inner ring respectively. External items can be placed in the outer cover plate 11 and the inner cover plate 13 to prevent foreign objects from causing wear of the deep groove ball bearing.

[0034] The ball bearing 10 rotates within the outer and inner rings and requires lubricating oil. An oil groove 1501 is provided inside the rear end of the left outer ring 1. An oil inlet 1502 is located at the upper end of the oil groove 1501. Lubricating oil enters the oil groove 1501 through the oil inlet 1502. After the lubricating oil is filled, the oil inlet 1502 is blocked by a plug 1503. A sealing ring 1504 blocks the connection between the plug 1503 and the oil inlet 1502 to prevent lubricating oil from overflowing. The lubricating oil in the oil groove 1501 contacts the outer side of the ball bearing 10 through the sponge block 1505, which can lubricate the ball bearing 10 and the inside of the deep groove ball bearing.
