[0024] In this embodiment, the centrifugal force can make the lubricating oil flow to the oil absorption gasket 6 under the action of the through hole 4 and the guide tube 5, and sufficient lubricating oil can be absorbed by the oil absorption gasket 6. The lubricating oil can be stored by the oil storage cotton ring 7, and the lubricating oil can be diverted by the guide groove 15. The cooperation of the guide cotton plate 16 and the oil seepage block 13 can divert the lubricating oil to the oil delivery hole 11, and the lubricating oil can slowly flow to the surface of the plastic gear body 1 through the oil seepage plug 12, so that the lubricating oil can be added to the plastic gear body 1 in time, thereby reducing the degree of wear on the plastic gear body 1.

[0025] Example 2
