Abstract:

An analytical formulation for the roller motion in a cylindrical roller bearing is presented in terms of the classical differential equations of motion. Roller-race interaction is analyzed in detail and the resulting force and moment vectors are determined. Formulation for the roller end and race flange interaction during skewing of the roller is also considered. Elastohydrodynamic traction models for the turbo-33 type oil, 5P4E polyphenyl ether, and the MIL-L-7808 oil are summarized for the purpose of computing rollerrace traction. The nature of the general motion of the roller is investigated by integrating the equations of motion for a typical roller bearing. It is found that very high frequency vibrations in the roller motion result from the rollerrace contact resonance. Author
