不同相位角对大节距输送链多边形效应的影响

滑道约束型输送链是一种新型链传动构型,合理选择各种参数有利于改善链条的工作性能。以一种特定情况下的输送链为研究对象,计算了从动链轮实时角速度变化规律,可以通过位移差表达多边形效应的大小,并能找出最佳初始相位角的范围。仿真结果表明,通过改变主从动链轮初始相位角的大小可以减小链条的多边形效应,以增加其稳定性,为滑道约束型链输送系统的设计提供了一定的设计依据。

Influence of Different Phase Angles on Polygon Effect of Long Pitch Conveyor Chain

The slideway restrained conveyor chain is a new type of chain drive configuration. Reasonable selection of various parameters is conducive to improving the performance of the chain. The conveyor chain of a specific case is taken as the research object, and the variation law of the real-time angular velocity of the driven sprocket is calculated. The size of the polygon effect can be expressed by the displacement difference, and the range of the optimal initial phase angle can be found. The simulation results show that the polygon effect of the chain can be reduced by changing the initial phase angle of the main driven sprocket to increase its stability, which provides a certain design basis for the design of the slideway-constrained chain conveyor system.
