Abstract

The kinematic and dynamic characteristics of high-speed cylindrical roller bearings are analyzed using the elastohydrodynamic (EHD) lubrication model developed in Part I of this two-part paper. The internal load distribution, bearing stiffness, running torque, and amount of roller skidding are calculated under various operating conditions. Effects of manufacturing imperfections are also analyzed in terms of outer-raceway waviness and roller diameter tolerance. Results obtained through case studies indicate that the behavior of the bearing can be significantly affected by EHD lubrication in the roller-raceway contacts.
