【摘要】：介绍了一种新型非圆齿轮液压马达的结构和工作原理。绘制出了该非圆行星齿轮系统中各个齿轮的节曲线以及齿廓图形。从非圆齿轮系统的动态性能出发,建立了非圆齿轮系统的扭振力学模型。模型中考虑了行星齿轮系统中各啮合齿轮的时变啮合刚度、啮合相位及齿轮副间隙。用Runge-Kutta方法对该系统的动力学微分方程进行了求解。以6~8类型的椭圆行星齿轮系统作为算例,得到该齿轮系统的时域响应,分析了间隙对该齿轮系统的动态特性的影响,为非圆齿轮马达的振动分析提供了理论依据。
[Abstract]:The structure and working principle of a new non-circular gear hydraulic motor are introduced. The pitch curve and tooth profile of each gear in the non-circular planetary gear system are plotted. Based on the dynamic performance of non-circular gear system, the torsional vibration mechanics model of non-circular gear system is established. The time-varying meshing stiffness meshing phase and gear pair clearance of each meshing gear in the planetary gear system are considered in the model. The dynamic differential equations of the system are solved by Runge-Kutta method. Taking the elliptical planetary gear system of 6 ~ 8 type as an example, the time-domain response of the gear system is obtained. The influence of the clearance on the dynamic characteristics of the gear system is analyzed, which provides a theoretical basis for the vibration analysis of the non-circular gear motor.
