摘　　要：通过分析球面接触时,轴承与轴颈间的相对运动关系,计算轴承对轴颈的摩擦阻力矩,得出球面接触与一般圆柱面接触的摩擦阻力计算方法的区别,为准确进行机械的力分析,平衡力的计算以及零件的设计计算打下基础。It get the differences between cylindrical surface contact and spherical surface contact of calculating friction resistance by analyzing the comparative relation of movement between bearing and axis neck while they contact, calculating the resistance moment of friction for bearing to axis neck. It will be a foundation of analyzing the force of machine accurately, calculating counterbalance and calculating parts designation.

关 键 词：球面接触 摩擦 当量摩擦系数 摩擦阻力矩
