This article mainly introduces the method that adopts gear caliper to measure the median diameter normaltooththickness of double-line trapezoidal thread.
本文主要介绍了采用齿轮卡尺测量双线梯形螺纹中径法向齿厚的方法,同时也测量出螺距产生的误差。

There is only approximate way to work out the normal chordal tooththickness of worm and wormwheel at present.
目前所见到的圆柱蜗杆蜗轮分度圆弦齿厚计算公式均为近似公式。

There is no common normal in the conical involute gear and the fixed chordal tooththickness can not be measured accurately because of the coexistence of helix angle and taper.
