A BASIC STUDY OF THE SLIDING CONTACTS IN ROLLING BEARINGS.

Abstract

Kinematics of rollers in a cylindrical roller bearing were further investigated using two distance gages mounted at a spacing of 30 degrees central angle. The output from these probes was tape recorded, the signals sampled, the sample amplitudes digitized and computer processed. Averages and standard deviations were obtained of the skew angle under both probes, the axial roller position under both probes, and the axial displacement of the roller between the two probes. Correlation coefficients were calculated between skew angles under the first and second probes, and between skew angle under the first probe and axial motion of the roller between the two probes. From these data, the angular position and axial motion of the rollers was analyzed in the load zone entrance region. Over forty tests with three mineral oil and diester base lubricants were conducted on a two-ball tester, covering several speeds and varying loads, to determine conditions for the onset of smearing at the contact between a stationary and a rotating ball.
