在加工非渐开线螺旋齿轮时,用公法线千分尺测量齿轮的法向弦长是一个较好的方法。本文导出了法向弦长和公法线千分尺安置角的精确计算公式。
When machining a non-involute helical gear, it is a good idea to measure the normal chord of the gear with a common-law micrometer. This paper derives the exact calculation of the normal chord length and the setting angle of the common-law micrometer.
