Abstract:
To obtain the simplified formula of viscous rolling resistance in the roller-raceway contact of tapered roller bearings, full EHD analyses in line contacts have been carried out for a wide range of dimensionless EHD parameters and meniscus distances in the inlet region. The results show that the effects of G and W on the viscous rolling resistance under full flooded conditions are small. However, the effects of U, G and W are influenced by the meniscus distance. The formula for frictional torque taking into account the simplified formula has been compared to the frictional torque obtained from experiment.
