摘要

摘要: 基于多体动力学方法,建立了计及游隙、外圈结构弹性变形、钢球和套圈接触关系的球轴承多体接触力学模型,结合自定义接触力程序,运用ADAMS计算不同载荷参数下球轴承的静态性能的变化规律。计算了联合载荷作用下钢球和套圈滚道的动态接触力,分析了球轴承的预紧力、径向力和联合载荷对钢球与套圈滚道的接触力、载荷分布角、套圈中心的相对位移和接触角等的影响,并通过理论计算进行了验证。

Abstract: The characteristics of rotating mechanical systems are importantly affected by load performance of ball bearings,the loads are the key external factors for static and dynamic characteristics of ball bearings. Considering clearance,structural elastic deformation of outer ring,contact relationship between balls and ring races,the multi-body contact dynamics model of ball bearings is established and simulated by ADAMS software with the user subrou-tine of contact force. The rule of static characteristics of ball bearing is studied for different loads. The dynamic contact force between balls and ring races has been calculated. The effect of preload,contact force duo to radial load and combined load,load distribution angle,relative displacements of rings' centers and contact angle are dis-cussed and verified by theoretical calculation.
