This paper presents a geometric model description methods of the conegear for final driver of automobile driving axle system based on STEP, and establishes application protocol (ZCAP).
Meanwhile, the handle and the cone of the gear shaft will have increased loads on gear, sleeve and workpiece.
同时，手柄对齿轮和齿轮轴的锥体对锥套及工件都会产生增力的作用。
