This paper presents a solution to the problem of hydrodynamic lubrication of highly loaded clastic cylinders under isothermal conditions. A numerical method is developed which enables a pressure curve to be found which satisfies the elastic and hydrodynamic requirements of the system.Results are presented which take account of elastic distortion and the dependence of viscosity upon pressure for centre-line pressures of 5, 10, 20, and 30 tonlin2. I n addition solutions are given for both rigid and elastic solids when the centre-line film thickness is the same in each case.
Recent work by the authors and others on the lubrication of elastic rollers is briefly reviewed. The full effects of speed over a wide range and of lubricant compressibility are presented for the first time. Speed is shown to be the most important variable in the problem. Compressibility has little effect on the film thickness, but it may alter the pressure distribution appreciably.
