摘要
针对一种柔性基座中的钢带传动装置传动比误差较大的问题,对其传动原理和传动规律展开了分析。对带轮的非圆廓形进行计算,得到钢带传动的理论传动比和钢带受力特点;采用有限元仿真对钢带传动进行模拟,分析了钢带局部塑性弯曲和螺钉孔处应力集中对理论传动比的影响;对柔性基座的实验数据进行误差分析,并对比了实验数据与仿真数据,两者具有较好的相符性。研究中重点分析了带轮廓形、钢带局部塑性变形和钢带弹性变形对传动比的影响,提出了改进方案,使得钢带传动成为精确传动。
Aiming at the problem that the transmission ratio error of a steel belt transmission device in a flexible base is large,the transmission principle and transmission law of the steel belt transmission device are analyzed.Firstly,the non-circular profile of the belt pulley is calculated,and the theoretical transmission ratio and the force characteristics of the steel belt are obtained.Then,a finite element simulation is used to simulate the steel belt transmission,and the effects of local plastic bending of the steel belt and stress concentration at the screw hole on the theoretical transmission ratio are analyzed.Finally,the error analysis of the experimental data of the flexible base is carried out,and the comparison of the experimental data and the simulation data shows that the two have a good agreement.In this study,the influence of belt profile,local plastic deformation and elas⁃tic deformation on transmission ratio is analyzed,and on this basis,the improvement scheme is put forward to make the belt transmission become accurate transmission.
