摘　　要：对非圆链传动进行初步运动分析。文中重点对非圆链传动（仅以椭圆链轮为例）机构瞬时传动比进行精确计算，所用公式由ＭａｔｈＣＡＤ推导得到。阐述了链轮齿数、链轮椭圆度与链传动中心距对瞬时传动比的影响，并在ＡｕｔｏＣＡＤ上显示、输出了相应的变化曲线。The kinematics of non circle chain drive was analyzed preliminarily. In this paper,instantaneous ratio of non circle chain drive was calculated precisely. The equations were gained by using MathCAD. The effects of number of teeth,ovality of sprocket and central distance of chain drive on instantaneous ratio was also expounded, and the varying curves were shown and exported using AutoCAD.
