1、no common normal in the conical involute gear and the fixed chordal tooth thickness can not be measured accurately because of the coexistence of helix angle and taper.───渐开线锥形齿轮由于同时存在锥度和螺旋角,使得其固定弦齿厚无法精确测量,也没有公法线。
2、only approximate way to work out the normal chordal tooth thickness 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。
