摘要/Abstract

摘要：

在外摆线方程的基础上,通过包络线法,求出外摆线等距曲线方程,从而得到外摆线滚子链轮齿廓曲线的一般表达式。在Pro／E中建立了外摆线链轮、国标GB1244-85标准链轮及日本JIS B 1801-90标准链轮的滚子链传动模型,并利用ADSAMS实现了3组模型在不同转速下的动态对比仿真。仿真试验结果表明外摆等距线滚子链轮能有效降低多边形效应的影响,更适合在高速下传动。

关键词: 外摆等距线链轮, 滚子链, 多边形效应

Abstract:

With the enveloped method, the epicycloid equation based on the epicycloid equidistant curve equation was obtained. The profile equation of the roller chain sprockets was obtained from the epicycloid equidistant curve. The roller chain drive models which match GB1244-85 standard sprockets, and Japanese standard JIS B 1801-90 sprockets, and the epicycloid equidistance sprockets were built by means of 3-D modeling techniques. Based on the ADAMS, under the condition of various rotating speed, dynamic simulation experiments were comparatively analyzed using three different profile models. The result showed that the chordal action can be reduced by using the epicycloid equidistance roller chain sprocket,which is more suitable for high-speed transmission.

Key words: epicycloid equidistance sprocket, roller chain, chordal action
