Bearing Capacity Analysis Of Four Point Contact Ball Slewing Bearing

Applying the finite element method, the function of finite element analysis software AnsysWorkbench is powerful. Analysis Influence of four point contact ball slewing bearing structure parameters on contact stress and deformation.According to the same model, the 1.25MW wind turbine yaw bearing. Analysis 30 groups of different groove curvature radius coefficient models,11 groups of different thickness of inner ring models,11 groups of different inner height models,10 groups of different rib height models,16 groups of different chamfer models, obtained the state of stress, deformation, change trend of analysis models. The results show that, when the inner and outer ring groove curvature radius coefficient, respectively 0.51 and 0.525, the bearing would get the maximum carrying capacity. The other studied parameters would get larger influence on slewing bearing. Calculation, results provide analysis basis for yaw bearing design.
