摘　　要：仔细分析了某型摩托车里程表主动齿轮(形式上相当于一个渐开线圆柱蜗杆)的轴向齿形。结果发现,对一些螺旋角很大的渐开线圆柱蜗杆,完全可以将其轴向齿廓看成直线段,并按阿基米德蜗杆来加工,这样可以大大降低加工难度,而且几乎不会对其齿形精度产生影响。The axial profile of an odometer driving gear(in form it's equal to an involute helicoid worm) in a certain model motorcycle is carefully analysed. It is discovered that the axial profiles of some involute helicoid worms of very big helix angle can absolutely be considered as straight lines and that they can be cut as straight sided axial worms. This will enormously reduce the manufacturing difficulty, and not pratically affect the profile errors.
