摘　　要：文章对双联齿轮轴上的齿轮和圆锥滚子轴承进行了受力分析,研究了圆锥滚子轴承的外部轴向力、由径向力产生的轴向分力及预紧力。结合圆锥滚子轴承寿命与轴向游隙的关系,并针对常用工况,计算了圆锥滚子轴承的最小预紧力。同时,研究了轴承预紧力与启动力矩,及启动力矩与锁紧螺母摩擦力矩的关系,可为装配提供简便的操作参考。In this paper,the force analysis of the gear and tapered roller bearing on double gear shaft is carried out.The external axial force,axial component force produced by radial force and preload of tapered roller bearing are studied.Combined with the relationship between the life and axial clearance of tapered roller bearing,the minimum preload of tapered roller bearing is calculated according to the common working conditions.At the same time,the relationship between the bearing preload and the starting torque,and the starting torque and the friction torque of the locking nut are studied,which can provide a simple operation mode for assembly.
