The new four-point contact bearings stress analysis

In this paper, by using Hertz theory the size of the contact angle different two new four-point contact ball bearing's contact stress and contact deformation were calculated, and compared to the contact stress and deformation of deep groove ball bearings, the calculated results point that when the new four-point contact bearing only bore radial force, its stress was better than the deep groove ball bearings, and the stress change of four-point contact ball bearing caused by different contact angle is obvious, but changes in the size of the contact area is not very different. Finally, with the finite element analysis software ANSYS-workbench, three sets of bearings' contact stress and strain have respectively carried out simulation analysis, and verify the correctness of the analysis results once again. The result of the new four-point contact ball bearing performance analysis and optimization design provides a reference basis, and have practical value.
