1.终传动装置结构推土机终传动装置的主要作用是将发动机传来的高转速小扭矩转化为低转速大扭矩,以实现推土机行走。其主要由锁紧螺母1、半轴2、后桥箱体3、轴承(4、10)、齿轮毂5、齿轮壳体6、链轮毂7、链齿8、锁紧盘9等组成,如图1所示。半轴2需先使用油压机将其与后桥箱体3压装在一起,再使用锁紧螺母1紧固。半轴2与齿轮毂5之间安装了轴承4和轴承10,齿轮毂5 1. The final drive structure Bulldozer final drive is the main role of the engine is coming from high-speed small torque into low-speed high-torque, in order to achieve bulldozers walking. The utility model is mainly composed of a lock nut 1, a half shaft 2, a rear axle box body 3, a bearing 4,10, a gear hub 5, a gear housing 6, a chain wheel hub 7, an element 8, a locking disk 9, Figure 1 shows. Axle 2 need to use the hydraulic machine with the rear axle box 3 pressed together, and then use the lock nut 1 fastening. Between the axle 2 and the gear hub 5 is mounted a bearing 4 and a bearing 10, a gear hub 5
