摘　　要：变位蜗杆传动中，如变位系数选取过大，可能导致蜗轮齿顶变尖，造成蜗轮强度下降，甚至磨倒掉屑，造成严重磨损，使传动过早失效．指出沿蜗轮齿宽最小齿顶厚出现的位置，推导了计算该最小齿顶厚的方法，并给出设计实例．It may result in sharp tooth head if the modification coefficient is too large in worm drive and with the result that the stuength of worm wheel teeth drop and even the chip may dvop from teeth head because wear and tear so that the wear is mere serious and failure earlier. Pointed out the position that the minimum tooth head thickness rise along worm wheel teeth width and supposed the method of calculating it.

关 键 词：蜗杆传动 变位系数 齿顶圆厚度 蜗轮
