摘　　要：提出了一种点接触摆线行星传动啮合副,推导了内摆线行星传动啮合管齿面方程和接触线方程。给出了设计实例并建立了三维模型。提出了一种利用接触线方程求解空间啮合齿面的滑动率的新方法,计算出点接触内摆线行星传动滑动率并对其主要影响因素进行了分析。结果表明,新型啮合副具有点接触特性,可获得近似纯滚动啮合,齿面滑动率小,传动效率高。A new gear pair of cycloidal planetary transmission with point contact is proposed. The equations of tubular meshing tooth surfaces and contact locus of internal cycloidal planetary transmission are derived respectively. The design example is given and the 3D solid models are established. A new approach for calculating the sliding ratio of tooth surface is put forward based on the contact locus. According to this method, the sliding ratios of internal cyctoidal planetary transmission with point contact are solved and the main influence factors are also analyzed. The results show that this new type of gear pair has the characteristic of point contact and the pure rolling between mated tooth surfaces can be obtained. Meanwhile, it has the higher transmission efficiency.
