Based on Bearing Centerless Strengthening and Polishing Processing Multiple Collision Finite Element Simulation Analysis
To further understand the bearing performance’s influence of the plastic deformation after balls and bearing rings surface multiple collision in ball bearing’s strengthening and polishing processing by the strengthening and polishing machine. ABAQUES software is used for finite element analysis in the three-dimensional modeling of multiple collision, and the plastic strengthen the performance of bearings is researched mainly. The results shows that the raceway surface is significant plastic strengthen in multiple collisions, Yield ability is enhanced largely, and surface residual stress state present for the compressive stress. Raceway surface strengthening process requires a particular number of times to ensure the processing, with strengthening processing times increasing, bearing raceway surface strength is saturated, then, the number continued to increase to strengthen, the surface strength is no significant increase. But after the collision of ball, uniform residual compressive stress is forming in the bearing surface, good for improving the fatigue strength and bearing life.
