摘　　要：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。本文给出了圆柱蜗杆及蜗轮轮齿在任意半径处弦齿厚计算的精确公式。特别指出 ,蜗杆蜗轮的分度圆弦齿厚与齿形无关。为了计算上的需要 ,文中引进了蜗轮弦齿厚计算斜齿轮的概念。There is only approximate way to work out the normal chordal tooth thickness of worm and wormwheel at present. An accurate calculation is given in this paper. It is pointed out especially that the normal chordal tooth thickness at the reference cylinder of worm and wormwheel is nothing to do with the type of worm. A new idea about calculation-gear is introduccd to meet the need of chordal tooth thickness.
