摘要：

Ball bearings are widely employed in machines for supporting/guiding the rotors in spite of their low inherent damping due to the poor retainability of lubricant at the contacts of races and balls. Thus, it has been planned to enhance the availability of grease lubricant at the contacts employing the textured race and investigating its role on the tribodynamics of bearing. Experiments have been conducted employing conventional/textured races in test ball bearings (SKF-51308) for the measurement of frictional torque, temperature rise, and vibrations at various operating parameters. Significant reductions in frictional torque, temperature rise and vibrations are observed with textured races.
