此方法不需要测头沿齿轮轴线方向的运动系统，利用齿形测量系统即可测量齿向误差。

The new method without movement paralleled with the axis of the gear makes the lead error measurement can share same generating system with profile measurement.

按齿轮轴线的相对位置分平行轴圆柱齿轮传动、相交轴圆锥齿轮传动和交错轴螺旋齿轮传动。

According to the relative position of sub-gear axis parallel shaft spur gear drive, bevel gear drive shaft and intersecting cross-axis helical gears.
