Abstract

Lubrication processes at rolling contacts are studied with a rolling-disk machine and X-ray system capable of measuring dynamic oil-film thickness and deformation at rolling contacts. Data are presented for a refined engine oil, a white mineral oil, and a polyphenyl ether over extended ranges of operating conditions. The measured minimum film thickness at rolling contacts transverse to the rolling direction with these lubricants, having bulk viscosities ranging from 6 to over 500 cp, varied from 3 to 100 microinches. For low-viscosity lubricants under moderate conditions of load, speed, and temperature, measured film thickness correlated well with elasto-hydrodynamic lubrication theory including elastic deformation of contact surfaces. Measured film thickness decreased significantly below theoretical under increasing load, speed, viscosity, and ambient temperature, by as much as a factor of 40. Elastic deformation tests at rolling contacts indicated that contact stresses were less severe for conditions of low load and high speed and with high-viscosity lubricants. A new theory of rolling contact lubrication was developed.
