(一)履带推土机在使用过程中,履带的链轨销与销套发生磨损,链轨节距拉长,销套与驱动轮之间会出现滑动现象,从而加快销套外径和驱动轮齿的磨损。如果继续使用,将会导致销套和驱动轮异常磨损,而且还会发生蠕动或波动现象。从磨损规律和受力情况来看,链轨销和销套可以翻新使用。D80A-12型推土机履带链轨 (1) During the use of a track bulldozer, the track pin and the pin bush of the track wear out, the chain track pitch lengthens, the sliding phenomenon occurs between the pin bush and the drive wheel, thereby accelerating the outer diameter of the pin bush and the driving gear teeth Wear and tear. If you continue to use it, it will cause abnormal wear of the pin bushes and drive wheels, and creep or fluctuation will occur. From the point of view of wear and force conditions, the chain pin and pin bush can be refurbished. D80A-12 bulldozer crawler track
