Chengdu Heavy - Duty Bearing Research Institute, Chengdu 610031,China) Abstract : According to the relationship of the roller contact stress and deformation, the calculation expression of the moment for cross - roller slewing bearings is got, and the analytical solution of the moment is calculated by using math-ematical integral formula, in the error allowed. For the bearings under axial force and torque load in the same time, the static axial loading - torque figure is drawn. The whole process of static load analysis for the crossed roller slewing bearings has been simplified. Key words : slewing bearing ; crossed - roller ; static load 转盘轴承一般都是在偏心载荷下工作的,因此轴承除了承受轴向载荷,还必须克服倾覆力矩的作用。其轴向静载荷- 力矩图是选择转盘轴承的主要依据。目前所沿用的计算方法是经过较复杂的过程进行推导,使用过程中还要査表获得相应的数据[1<。为避免繁琐的数值计算,本文针对交叉滚子转盘轴承载荷进行分析。首先在倾覆力矩
