摘　　要：通过对带传动张紧力大小造成传动轴变形而引起带轮偏心的分析,得出了因不同张紧力造成带传动回转运动误差的计算方法和相关公式,并基于PDJ-4型带传动实验机给出的分析实例,得出了随着张紧力的增加回转运动的误差有所增加的结论。带传动张紧力过大时,将产生较大的回转运动误差,并最终提出了改进方案和措施。Through the analysis of the shaft deformation caused by the pulley eccentric,the calculation method and related formulas for belt drive rotary motion error caused by different tension are obtained.And based on the analysis examples given by PDJ-4 belt drive experiment facility,the conclusion that with the increase of tension,rotary motion error increases at the same time is obtained.Thus it will have a greater rotary motion error when the tension is too large,and the improvement scheme and measures are proposed.
