Introduced to traditionally roll over theories and calculation method of the bearings life span, pass the usage Pro/E software, built up to roll over the analytical 3D model of the bearings contact, and use ANSYS software to carry on a limited dollar analysis towards rolling over bearings, include a limited dollar the choice of the unit among them, limited dollar the demarcation of the mesh, carry lotus and boundary to conditionally add to carry, solve procedure of control and to as a result carry on postpose processing and analyze.Pass to compute result contrast analysis with traditional ories, prove the analysis is correct and explain that method the analysis is viable, also for the bearings dynamics imitate true analysis provided theories foundation.

Introduced the traditional rolling bearing life theory and the computational method, through use the Pro/E software, has established the rolling bearing contact analysis three-dimensional model, and uses the ANSYS software to c
