直齿圆柱变位齿轮的一种测绘方法

A Method of Measurement of Spur Gears with Addendum Modifications

在工程实践中对损坏的无图纸齿轮进行重新制造时 ,测绘是必不可少的环节。在齿面已被严重磨损的情况下 。

It is a necessary procedure to make measurements in engineering practices before some gears whose blueprints are not available are reproduced. This paper discusses emphatically how to obtain the accurate parameters of these gears, especially those with addendum modifications under the condition of serious gear tooth surface abrasion.
