摘　　要：纯滚动单圆弧齿轮是一种新型的圆弧齿轮,为了研究其振动特性,利用Pro/E建立纯滚动单圆弧齿轮的三维实体模型,然后导入到ANSYS中对该齿轮进行模态分析,分别得到纯滚动凸圆弧齿轮和凹圆弧齿轮的固有频率、振型及临界转速;讨论了不同齿数、模数、螺旋角情况下齿轮的固有频率,讨论结果为纯滚动单圆弧齿轮的优化设计和动态响应分析研究提供基础。Pure rolling single arc gear is a new type of circular arc gear. In order to study its vibration characteristics, the three-dimensional solid model of pure rolling single arc gear was established using Pro/E. Then, the modal analysis of the gear was introduced into the ANSYS, and the natural frequency, vibration mode and critical speed of the pure rolling convex circular arc gear and concave circular arc gear were obtained. The natural frequency of gears with different teeth number, modulus and helix angle is the basis for the optimization design and dynamics research of the pure rolling single arc gear.
