Analysis of Sealing Performance of Rolling Bearings Based on Materials and Geometric Structures
The sealing performance of rubber dust cover for deep groove ball bearing is simulated and analyzed by finite element method.By simulation analysis,the influence of the interference between the rubber material and the sealing lip on the sealing performance of the sealing cover was obtained.The results show that hydrogenated nitrile rubber with sufficient contact pressure and low friction torque is more suitable for sealing;the contact pressure distribution is reasonable when the interference is between 0.05 mm and 0.07 mm,the generated friction torque is small,and the sealing performance is the best.When the interference of the sealing lip is greater than 0.07 mm,the contact pressure starts to shift.
