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。 On the basis of the equation of the epicycloidal equation, the equation of the equilateral curve of the epicycloidal equation is obtained by the envelope method, and the general expression of the profile curve of the cycloid roller chain sprocket is obtained. In the Pro / E established a cycloid sprocket, the national standard GB1244-85 standard sprocket and Japan JIS B 1801-90 standard sprocket roller chain drive model and the use of ADSAMS achieved three sets of models at different speeds Dynamic contrast simulation. The simulation results show that the out-swing isokinetic roller chain sprocket can effectively reduce the effect of polygon effect, and is more suitable for transmission under high speed.
