摘要
论述了渐开线锥蜗杆蜗轮Ⅱ传动的几何原理，它实质上是渐开线变厚齿轮交错轴传动；推导了无侧隙关系式．它一侧齿面是点接触，另一侧齿面属于线接触．齿面接触强度高，便于齿面精加工。
The geometric principle of the transmission of involute conical warm and warmwheel is discussed,that is the transmission of involute gears of varing tooth thickness with non－parallel non intersecting axes. The transmission system has point contact on one flank and line contact on the other. The fatigue strength of the tooth flank is great,which is easy for the precise machining of tooth flank.
