摘要
本文从运动学及数学角度对链传动进行了分析，给出了从动链轮速度、加速度与中心距之间的关系。分析了从动链轮速度、加速度在一个节距角内变化的情况，考虑磨损使中心距发生变化所引起的链传动运动学特性的变化，给出选择链传动中心距的方法。
The kinematic charactevistics of chain drives are analyzed, the relationshiys between the speed and aacceleration of the driaen sprokte and the centre distance are driaen sprocket within the range of pitch angle are studied. considering the variation of kinematic characteristics caused by the change of centre distarce resulted trom wear, a method for selecting the centre distance is proposed.
