摘要
在深沟球轴承动力学分析基础上,建立了低噪声深沟球轴承动态性能仿真数学模型,利用ADAMS多体动力学分析软件,开发了低噪声深沟球轴承仿真分析软件,对6205型低噪声深沟球轴承进行了仿真分析,探究了轴承径向游隙,内、外沟曲率半径系数,保持架兜孔引导间隙,保持架偏心距,轴向、径向载荷以及转速等参数对轴承振动的影响,结果表明:轴承径向游隙,内、外沟曲率半径系数对轴承本底振动有较大影响;合理的保持架兜孔形状以及兜孔半径均可减小轴承振动;施加一定的轴向载荷能够有效减小轴承振动,提高轴承寿命。
A mathematical model is established to describe the dynamic behavior of low - noise deep groove ball bearing based on the dynamic analysis of deep groove ball bearing, and then the simulation analysis software is developed using the multi - body dynamic analysis software ADAMS. Taking low - noise bearing 6205 as example, the bearing vibration is analyzed at various radial clearances, the groove curvature coefficients of inner and outer rings, the pocket guidance clearance and eccentricity of cage, the radial and axial loads, and the rotating speed. The simulation results show that the bearing basic vibration is mainly effected by the radial clearance and the groove curvature coefficients of inner and outer rings, an appropriate structure of pocket and a reasonable pocket radius being helpful to decrease the bearing vi- bration, and the bearing vibration will decrease effectively and the bearing life will increase when the applied axial loads in a certain range.
