Tapered Roller Bearing System is widely used in rotating machinery system, the dynamic performance has a significant impact on rotating machinery. In this paper, 30207 Tapered roller bearings as an object, used Romax software to build the dynamic model of tapered roller bearing system, we studied the contact stress distribution and the roller contact stress distribution between the bearing rollers and roller path; based on tapered roller bearing structure and working conditions, we conducted a tapered roller bearing fatigue life calculation of the load distribution, stress level and so on, to verify the reasonableness of bearing design parameters. In addition, we studied the affect of stress distribution on the number of rollers between the bearing rollers and roller path. The optimized design while shortening design cycles, improve the success rate of new product development. Keywords-Romax; modelling; bearing; virtual
