摘要

提出了一种可实现等速往复运动规律的组合机构，该机构由一对非圆齿轮传动机构与一个正弦机构串联组合而成；当主动齿轮均速转动时，可严格实现正弦机构从动件等速往复运动。讨论了根据从动件等速往复运动规律确定非圆齿轮节曲线的运动学设计反求方法，并给出了多个非圆齿轮节曲线的设计方案，证明了该组合机构实现等速运动规律的有效性。该组合机构可广泛应用于需要准确实现等速运动规律且传递较大功率的机器主传动系统，如机械传动式拉压疲劳试验机、机械传动式减震器试验机等。

Abstract

A combined mechanism which can realize constant speed reciprocating motion of its follower is presented. The mechanism is composed of a pair of non-circular gears and a sine mechanism in series. When the driving gear rotates at the fixed speed, the constant-velocity reciprocating motion of the follower in the sinusoidal mechanism can be strictly realized. An inverse kinematic design method is researched to determine the pitch curves of the non-circular gears according to the constant speed reciprocating motion of the follower and different pitch curves of the non-circular gears are obtained. All these works prove that the combined mechanism can be effectively realized the uniform motion of the follower. The combined mechanism can be widely used in the main drive systems of the machines that need to realize the constant speed motion accurately and transfer high power such as the reciprocating fatigue testing machine, shock absorber tester with mechanical transmission mechanism, etc.
