Ball-Ring Friction at Low Rotating Speed
Journal Title: Tribology in Industry - Year 2009, Vol 31, Issue 1
Abstract
The paper presents an experimental research of rolling friction between a ball and a ball bearing ring. An original computer assisted test rig was build in order to evaluate the rolling friction phenomenon, between balls and ball-bearing rings. Dry and lubricated contacts with three different lubricants were tested at very low rotating speed, starting from zero. Influences of kinematics and lubricant type and quantity upon friction were revealed. All experiments reveal a low increasing tendency of friction with speed. Conclusions about rolling friction phenomena and friction in lubricant presence are presented. Some considerations about film generation in ball-ring contact are presented, too.
