多锥构型摩擦副同步过程的影响因素分析
U463.2%TH117.1; 基于润滑力学和微凸体摩擦原理,建立了多锥构型摩擦副同步过程的数学模型并进行数值求解,分析了多锥构型摩擦副同步过程中主从动片初始相对转速、油膜厚度、油膜承载力、微凸峰承载力、黏性剪切转矩、粗糙摩擦转矩等随同步时间的变化规律.利用所建模型研究了锥角、摩擦锥面数量、表面粗糙度、初始相对转速和加载压力等因素对同步过程的影响规律.结果表明:多锥构型摩擦副具有明显的楔形自增力效应,较小的轴向加载力可提供很大的锥面接触力;减小锥角、增加摩擦锥面数量、增大表面粗糙度和轴向加载压力均可提高同步转矩,缩短同步时间;同步时间与初始相对转速大致呈线性关系....
