矿用挖掘机行走机构常用履带传动装置。其特点是以驱动轮和履带板作为啮合副,并以履带板组成履带链作为轨道面来实现挖掘机的行走运动,这就要求驱动轮和履带板具有合理的啮合齿形,以使运动平稳、零件受力合理,提 Mining excavators travel agencies commonly used crawler gear. The utility model is characterized in that the driving wheel and the crawler plate are used as the meshing pair, and the crawler chain is used as the track surface to realize the walking movement of the excavator, which requires that the driving wheel and the crawler plate have a reasonable meshing tooth shape so as to make the movement stable , Parts force reasonable, mention
