By setting the upper connecting ring 11, through the combination of the upper connecting ring 11 and the upper connecting slot 12, the lubricating oil will not flow out through the gap between the inner ring 13 of the bearing and the upper protective shell 2, thus solving the problem that the axial sealing ability of the self-lubricating bearing is weak and oil will leak when the bearing is axially tilted; achieving that the self-lubricating bearing does not leak oil under short-term axial tilt;
[0021] An outer arc surface of the inner ring 13 of the bearing is fixedly connected with a lower protective shell 14, a movable slot 15 is opened on the lower protective shell 14, a movable column 16 is movably connected to the inner wall of the movable slot 15, and the number of the movable columns 16 is two and they are symmetrically distributed in a mirror image. By setting the movable column 16, as the bearing rotates, the movable column 16 rotates simultaneously, thereby driving the ball 17 to rotate;
[0022] The movable column 16 is provided with a ball 17, and a threaded groove 18 is opened on the outer arc surface of the ball 17. By setting the threaded groove 18, the threaded groove 18 can stir the lubricating oil inside the bearing through the ball 17, thereby improving the lubrication effect of the lubricating oil;
[0023] An outer arc surface of the lower protective shell 14 is fixedly connected with a lower connecting ring 19, a lower connecting slot 20 is opened on one side of the outer ring 1 of the bearing close to the lower connecting ring 19, and the lower connecting ring 19 corresponds to the lower connecting slot 20. By setting the lower connecting ring 19, the lower connecting ring 19 is combined with the lower connecting slot 20, so that the outer ring 1 of the bearing and the inner ring 13 of the bearing can be assembled more firmly;
[0024] The upper protective shell 2 is provided with installation threaded holes 3. The number of the installation threaded holes 3 is two and they are distributed symmetrically in a mirror image.
