钻机车分动箱一轴后端的改进方法

An improvement of rear of first axle in truck-mounted-rig-used transfer case

钻机车的分动箱一轴后端的花键常被磨损或变形,无法实现动力的正常传递,因此必须进行维修。维修时,通常是更换分动箱总成或对分动箱解体更换一轴,既费时也不经济。若将一轴后端进行改进,就能很好地解决这一问题。

In practice, the splines in rear of first axle of transfer case are often worn out or deformed, failing to finish the normal transmission of power, which should be maintenance. In maintenance, we often replace the assemblage of transfer case or change the first axle by disintegrating the transfer case, which is both time-consuming and expensive. But improving the rear of first axle can better solve this problem.
