摘要
针对实际工况下行走式减速器齿轮传动不平稳导致的较大振动和噪声问题,以二级行星减速器为对象,通过Pro/E软件建立三维模型,基于多体动力学仿真软件ADAMS建立动力学模型,对减速器传动系统进行动力学研究.结果表明:根据推导的传动比公式,进行各部件理论转速与仿真转速对比,验证了该模型的正确性.对多组阻尼系数进行仿真分析可知,适当的阻尼系数能提高系统的稳定性,最优阻尼系数为0.1%K.基于最优阻尼系数进行动力学仿真分析可知,二级行星轮与齿圈啮合冲击是振动的主要来源.在实际生产中,可以通过选择不同的润滑方式来减小齿轮啮合冲击.
In order to solve the problem of large vibration and noise caused by the unsteady gear transmission of the traveling reducer under actual working conditions,the two-stage planetary reducer was taken as the object.A three-dimensional model was established through Pro/E software and a dynamic model was established based on the multi-body dynamics simulation software ADAMS to study the dynamics of the reducer transmission system.The results showed that according to the formula of transmission ratio,the theoretical speed of each component was compared with the simulation speed,and the correctness of the model was verified.The simulation analysis of multi-group damping coefficients showed that appropriate damping coefficients could improve the stability of the system,and the optimal damping coefficient was 0.1%K.According to the dynamic simulation analysis based on the optimal damping coefficient,the meshing impact of the secondary planetary wheel and gear ring were the main source of vibration.In actual production,different lubrication methods could be selected to reduce the meshing impact of the gear.
