摘　　要：提出一种分析蜗杆传动齿面磨损量的计算模型,用Archard磨损公式,推导出齿面磨损深度的计算公式。以阿基米德蜗杆副为例,利用空间啮合原理求解出其齿面接触线和相对滑动速度。并在计算过程中引入啮合循环和时间步骤的概念,研究了该种传动副齿面磨损的分布规律,分析了齿面磨损深度的影响因素和一般规律。An analysis model for wear simulation in worm gears has been developed. Wear is calculated based on Archard＇s wear law. Formulae are given for the teeth faces of worm gear drives. ZA examples are provided. Contact lines and relative slide speeds are worked out according to mesh theory. Based on the above results, a conception of the mesh cycle and time step are used in calculations, wear value changes are presented, and the factors effecting wear values and their effects are discussed.
