Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example 1: a self-lubricating bearing, as shown in figures 1 to 3, comprises a bearing outer ring 1, a bearing inner ring 2, balls 3 and a self-lubricating retainer 4. Self-lubricating holder 4 includes upper bracket body 5, lower bracket body 6, oil storage axle 7 and retaining wheel 8, oil storage axle 7 and lower bracket body 6 fixed connection, lower bracket body 6 cavity sets up. An oil filling hole 14 is formed in the lower frame body 6, and a sealing plug 15 is connected to the oil filling hole 14 in a threaded mode. The retaining wheel 8 comprises a rotating hole 9, the rotating hole 9 is matched with the oil storage shaft 7, the oil storage shaft 7 comprises an oil storage cavity 10 and an oil outlet 11 leading to the oil storage cavity 10, and the oil outlet 11 is arranged on the side face of one end, close to the lower frame body 6, of the oil storage shaft 7. A layer of oil absorption paper 12 is arranged on the circumferential side surface of the retaining wheel 8, and an oil absorption hole 13 leading to the oil absorption paper 12 is formed in the inner wall of the rotating hole 9. The retaining wheel 8 comprises a first state, when the retaining wheel is in the first state, the oil suction hole 13 is communicated with the oil outlet hole 11, and the upper frame body 5 is connected with one end, far away from the lower frame body 6, of the oil storage shaft 7.
