[0029] A plurality of balls 4 are movably mounted in the ring frame 3, and the design of the ring frame 3 ensures the uniform distribution and stable operation of the balls 4.

[0030] Arc-shaped ring grooves 13 are arranged on the outer side of the inner ring 1 and the inner side of the outer ring 2, the arc-shaped ring grooves 13 are matched with the plurality of balls 4, and the design of the arc-shaped ring grooves 13 enables the balls 4 to better fit the surfaces of the inner ring 1 and the outer ring 2 when rolling.

[0031] A sealing ring 14 is arranged on the bottom surface of the mounting sleeve 7, the sealing ring 14 is in close contact with the bottom surface of the sealing sleeve 9, the sealing ring 14 and the bottom surface of the sealing sleeve 9 are in close contact, and an effective sealing barrier is formed.

[0032] The limiting sleeve 8 is in sliding connection with the sealing sleeve 9 in a polygonal shape, and the polygonal structure of the limiting sleeve 8 can also prevent the sealing sleeve 9 from deviating during sliding.

[0033] The outer end of the stop block 10 is designed in an arc shape, and the design of the arc shape enables the stop block 10 to better adapt to the shape of the ball 4 when in contact with the ball 4.

[0034] In the embodiment, when the bearing is in operation, the balls 4 between the inner ring 1 and the outer ring 2 roll continuously, generating certain friction and heat. At this time, the lubricating oil in the oil storage compartment 6 gradually flows out through the plurality of oil flow holes 11. The opening and closing of the oil flow holes 11 are controlled by the relative movement of the sealing sleeve 9 and the abutting block 10. Specifically, when the balls 4 roll along the arc-shaped ring groove 13, the abutting block 10 is abutted and pushed, the abutting block 10 pushes the sealing sleeve 9 to slide along the limiting sleeve 8, so that a flow space is generated between the sealing sleeve 9 and the mounting sleeve 7. After the lubricating oil flows out through the oil flow holes 11, it flows out through the gap between the sealing sleeve 9 and the mounting sleeve 7, and is uniformly distributed between the balls 4 and the raceway, forming a lubricating film to reduce friction and wear.

[0037] More specifically, when it is necessary to supplement the lubricating oil, the sealing plug 22 is first pulled out of the through hole 21, and then the operator can inject lubricating oil into the oil storage compartment 6 through the oil injection sleeve 16. Specifically, the operator screws the nozzle of the oil injection gun into the threaded sleeve 20, pushes the piston of the oil injection gun, and the lubricating oil enters the oil injection sleeve 16 through the oil injection threaded sleeve 20. Under the pressure of the lubricating oil, the pressure receiving sleeve 18 in the oil injection sleeve 16 slides along the slide rod 17, and the pressure spring 19 is compressed. The pressure receiving sleeve 18 uniformly distributes the lubricating oil into the oil storage compartment 6. When the piston of the oil injection gun stops pushing, the elastic force of the pressure spring 19 resets the pressure receiving sleeve 18 to ensure the sealing of the oil injection hole 15.
