单配圆柱斜齿轮的测绘方法

圆柱斜齿轮的测绘，难点就在测绘其分度圆螺旋角，介绍了用公法线长度来计算其法向模数。再用公法线长度及齿顶圆直径互推法来估算变位系数及分度圆螺旋角，然后用滚齿机校验分度圆螺旋角，从而算出准确的参数，测绘的精确度都能满足单配的要求。

Introduce a kind of measure the method about single to go together with cylinder bevel gear

The difficult point of plotting cylinder bevel gear lies on the surveying its helical angle of scale division circle.This text introduces a good way to solve it.First we shall calculate normal module with the length of public normal line.Then we can estimate coefficient of displacement and helical angle of scale division circle under the derivation between the length of public normal line and the diameter of crown circle.Finally,we must use the gear hobbing machine to check helical angle of scale division circle.So we can figure out the accurate parameters.The accuracy of surveying should be able to fulfil the requirement of single adaptation.
