| Abstract: | By analyzing load distribution of two sets of rollers for cross-roller slewing bearings,the roller which bear maximum load is determined,and the values of surface and sub-surface stress are calculated.Because of seamless connection between Pro/E and ANSYS Workbench,the slewing bearing model set up in Pro/E is put into ANSYS Workbench for FEA.The result is compared with traditional theoretical analysis in order to prove the correctness of FEA.It provides a scientific basis for optimization design and fatigue life analysis of slewing bearings. |
