The working principle is as follows: during the use, can store lubricating oil in the inside of oil absorption material, the rotary drive connecting axle when needs are lubricated, because it is threaded connection with the sprocket shaft body, the position of drive connecting axle can change this moment, drive promotion piston extrusion oil absorption material, the inside of installation cavity is extruded through the lubricated passageway of producing oil to the lubricating oil that the oil absorption material can store before this moment, play lubricated effect, the setting of the loudspeaker shape of the lubricated passageway of cooperation producing oil, not only can play the moist operation of regular portable, also can avoid external impurity to get into the inside of installation cavity simultaneously, when the rotary motion is done to the drive connecting axle, fixed cover is established and is being promoted the buffering sealed soft layer of piston surface and can play the effect of automatically cleaning to the inside of installation cavity, also can utilize this function to clean the inside of drive connecting axle in follow-up used repeatedly process.

(III) advantageous effects

The invention provides a maintenance-free self-lubricating chain wheel shaft. The method has the following beneficial effects:

1. non-maintaining self-lubricating sprocket shaft promotes the piston extrusion oil absorption material, and the oil absorption material can extrude the inside of installation cavity through the lubricated passageway of producing oil with the lubricating oil of storing before this moment, plays lubricated effect, and the setting of the loudspeaker shape of the lubricated passageway of cooperation producing oil not only can play the moist operation of regular portable, also can avoid external impurity to get into the inside of installation cavity simultaneously.

2. The maintenance-free self-lubricating chain wheel shaft drives the connecting shaft to do rotary motion, the buffering sealing soft layer fixedly sleeved on the outer surface of the pushing piston can play a self-cleaning effect on the inside of the mounting cavity, and the function can be utilized to clean the inside of the driving connecting shaft in the subsequent repeated use process.
