The primary function of bearing seals is to prevent lubrication from escaping and foreign materials from entering. The effectiveness of such function is determined by the design of the seal lips. Bearings with low friction rotation are in great demand in the automotive market as a direct result of the regulations stipulating vehicle fuel economy and reduced CO2 emission. Therefore, bearings with a good sealing function and low friction rotation are required. In this paper, estimation of the bearing rotational torque through numerical analysis, based on finite element methods, was investigated. This included calculation of the bearing rotational torque using an axisymmetric model from the commercial software, ANSYS. The seal rubber material properties were performed with three kinds of tension tests and were analyzed using the hyperelastic method for increased accuracy. The results of the analysis were compared with the empirical results and a strong correlation was confirmed. |
