摘要

以三齿差摆杆活齿传动系统为研究对象,考虑主要构件误差、啮合刚度因素,建立三齿差摆杆活齿传动系统的等价误差模型,根据牛顿第二定律构建系统的动力学方程,分析各单项误差作用下活齿架的振动响应,确定对活齿架振动响应影响较大的关键误差,并通过对考虑主要构件全部误差和只考虑主要构件关键误差的活齿架振动响应对比分析,证明关键误差是影响活齿架振动响应的主要因素,再利用ADAMS进行振动仿真验证理论分析结果,最后加工两组不同精度的激波器、中心轮,试验分析改善关键误差后活齿架的振动响应变化,结果表明,通过控制关键误差可有效改善传动系统的动态特性。研究结果可为合理设计分配三齿差摆杆活齿传动系统各零件加工误差提供理论依据。

Abstract

Taking the three-tooth difference swing-rod movable teeth transmission system as the research object, the equivalent error model of the three-tooth difference swing-rod movable tooth transmission system is established considering the main component error and meshing stiffness factors. And the dynamics equation of the system is established based on Newton's second law. By comparing the vibration response of separator considering all errors with that considering only critical errors, it is proved that the critical error is the main factor affecting the vibration response of the separator. Then, ADAMS is used for vibration simulation to verify the theoretical analysis results. Two groups of wave generators and ring gears with different accuracy are processed, and the vibration response of separator is tested. The results show that the dynamic characteristics of the transmission can be improved effectively by controlling the critical errors. This study can provide a theoretical basis for the rational allocation of machining errors of the three-tooth difference swing-rod movable teeth transmission system.
