Abstract
The utility model provides a gear disengaging prevention mechanism of a snowmobile crawler belt walking device, and belongs to the technical field of snowmobiles. The gear disengaging prevention mechanism solves the problems that according to an existing snowmobile crawler belt walking device, loosening, gear disengaging and the like can occur between a driving wheel and a fixing piece of the driving wheel. The gear disengaging prevention mechanism is arranged on a rotating shaft and located on one side of a driving gear. The gear disengaging prevention mechanism comprises an annular gasket which is arranged on the rotating shaft in a sleeved mode and clamped between a limiting nut and the driving gear. A clamping block is arranged on the inner circle of the gasket. A clamping groove corresponding to the clamping block is axially formed in the rotating shaft. The clamping block is clamped in the clamping groove so that the gasket can be prevented from rotating. A plurality of folded pieces are distributed on the outer circle of the gasket in a radiation mode and can be bent relative to the gasket and attached to the outer side face of the nut. By means of the gear disengaging prevention mechanism, loosening and gear disengaging can be prevented from occurring between the driving gear and the limiting nut, and the snowmobile can be supported to work for a longer time.
