[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] This embodiment is a self-lubricating bearing.

[0025] like Figure 1-4As shown, it includes an oil distribution hole 9, a bearing outer ring 1, a bearing inner ring 2, a dust ring 3 and a ball 10. The number of the dust ring 3 is two groups. The two groups of dust rings 3 are located between the left and right ends of the inner wall of the bearing outer ring 1 and the left and right ends of the outer wall of the bearing inner ring 2. The ball 10 is located between the inner wall of the bearing outer ring 1 and the outer wall of the bearing inner ring 2. An oil filling joint 4 is fixedly installed on the upper part of the outer surface of one end of the bearing outer ring 1, a fixing plate 5 is provided on one side of the outer surface of one end of the bearing outer ring 1, and a noise sensor 6 is fixedly installed on the outer surface of one side of the fixing plate 5. An annular oil channel 11 is opened inside the bearing outer ring 1, a first annular limiting groove 7 is opened on the inner wall of the bearing outer ring 1, and a second annular limiting groove 8 is opened on the outer wall of the bearing inner ring 2. The oil distribution hole 9 is opened between the annular oil channel 11 and the first annular limiting groove 7.

[0026] A fixing screw is provided between the fixing plate 5 and the bearing outer ring 1, and the fixing plate 5 is fixedly connected to one side of the outer surface of one end of the bearing outer ring 1 through the fixing screw; the noise sensor 6 is externally connected to a controller with an alarm; one end of the oil filling connector 4 extends into the annular oil channel 11, and the oil filling connector 4 is externally connected to a lubricating oil supply pump; the oil distribution hole 9 is connected with the annular oil channel 11 and the first annular limit groove 7; the ball 10 is located between the first annular limit groove 7 and the second annular limit groove 8.
