Abstract
A ball-bearing simulator was designed and constructed at our laboratories. This simulator replicates the essential features of a ball bearing, and allows for a variety of cage materials and solid film lubricants to be evaluated under simulated operating conditions. The geometry employed consists of a bearing ball sandwiched between two rotating inner-bearing races, and various levels of ball-race slip are imparted by changing the speed difference between the two races.
Preliminary experiments with PTFE, graphite-resin, and molybdenum disulfide film show the PTFE film to have the lowest traction coefficient, while the transfer film produced by the graphite-resin composite had the highest traction coefficient. The molybdenum disulfide film produced a relatively low traction coefficient, but was quickly worn away.
