针对常规转盘轴承无法同时实现低摩擦力矩、高精度、高转速、高刚性的问题，设计了一种低扭矩高刚性推力球和圆柱滚子组合转盘轴承的新型结构。%Aiming at the problem that conventional slewing bearings can not realize low friction torque,high precision, high rotation speed and high rigidity,a new structural design is introduced for slewing bearings combined with thrust balls and cylindrical rollers with low torque and high rigidity.
