摘　　要：建立了直齿行星齿轮的动力学模型.其中,齿与齿之间的啮合非线性由弹簧-阻尼器-间隙-啮合误差环节模拟.提出了一种以行星轮转角为变量的时变啮合刚度与时变啮合误差表达形式,解决了变转速下行星齿轮动力学模型的描述和求解问题.通过对动力学模型进行求解,分别研究了转速、齿侧间隙、啮合误差和负载等重要参数对行星齿轮动力学特性的影响.The dynamic model of the spur planetary gear was established.The mesh nonlinear between gear teeth was described by the spring-damper-clearance-mesh error.The expressions of the time-varying meshing stiffness and the time-varying meshing error with the rotation angle of the planetary gear as a variable were proposed which solved the problems of describing and resolving the dynamic model of the planetary gear under the variable speed.Then,by solving the dynamic models,the effects of the important parameters such as rotational speed,tooth side clearance,meshing error and the load on the mechanical property of planetary gear were analyzed.
