摘要

为满足行星齿轮与滚动轴承集成设计需求,基于多体动力学理论和弹性接触理论,提出一种考虑行星齿轮与滚动轴承动态相互影响且能计算各滚动体接触载荷的行星齿轮-滚动轴承耦合系统动力学建模方法。以风电机组行星齿轮滚动轴承系统为研究对象,构建其耦合系统动力学模型,研究行星齿轮与滚动轴承间的耦合作用机理。研究发现：行星齿轮对滚动轴承动态响应影响显著,受齿轮啮合力影响滚动体接触载荷与轴承偏心轨迹呈高频波动特征,设计时应充分评估行星齿轮对滚动轴承动态响应影响。

Abstract

In order to meet the integrated design requirements of planetary gear and rolling bearing, a dynamic modeling method of planetary gear-rolling bearing coupling system based on multi-body dynamics theory and elastic contact theory is proposed. The model not only considers the dynamic interaction between planetary gear and rolling bearing, but also calculates the contact loads of each rolling body. Taking the planetary gear-rolling bearing system of wind turbine as the research object, the dynamic model of its coupling system is constructed and the coupling mechanism between planetary gear and rolling bearing is studied. The results show that the planetary gear has a significant influence on the dynamic response of rolling bearings. Affected by gear meshing force, the rolling element contact load and the bearing eccentric trajectory show the high-frequency fluctuation characteristics. The influence of planetary gears on the dynamic response of rolling bearings should be fully evaluated in the design.
