摘要： 为减少刚性摆线针轮行星减速器工作时的振动,提高运行可靠性,设计了一种带减振衬垫的非刚性摆线针轮行星减速器,并对其进行非线性振动分析。综合考虑了时变刚度、轴向误差、啮入冲击等激励,基于集中参数理论和牛顿第二定律建立新型摆线针轮行星减速器8自由度的多因素耦合动力学模型和振动微分方程组,采用变步长四阶Runge-Kutta法对量纲归一化后的方程组进行求解。对比了刚性与非刚性结构下的摆线轮、低速轴的垂直振动和扭转振动情况,结果表明:采用减振衬垫,使摆线轮和低速轴的垂直振动和扭转振动效应都降低。进一步对新型摆线针轮行星减速器进行实验测试分析,结果表明:实验所测数据结果与其振动情况的理论分析结果较吻合。

Abstract: In order to reduce the vibration of rigid pin-cycloid speed reducer and improve its operational reliability, a non-rigid pin-cycloid speed reducer with damping mat is designed its nonlinear vibration characteristics are analyzed. Taking into consideration of three internal excitations, including time-varying stiffness, axial error and meshing impact, an eight-degrees of freedom multi-factor coupling dynamic model of the designed pin-cycloid speed reducer is established based on the theory of concentrated parameter, and the vibration differential equations are set up based on Newton second law. Then, the equations are solved by adopting the fourth-order Runge-Kutta algorithm with variable step length. The verticality and the torsion vibration characteristics of the cycloid gear and low speed shaft of the new pin-cycloid speed reducer are compared with that of traditional one. Results show that the verticality and the torsion vibration of the cycloid gear and low speed shaft are reduced by the damping mat. Also the theoretical analysis is verified by measurement data from the test of the new reducer.

Key words: mechanical design, new pin-cycloid speed reducer, damping mat, non-linear vibration characteristic, dynamic design
