Abstract

The investigated case is: Two rotating steel cylinders, infinitely long and with effective radius of curvature of 5 cm, are loaded to Hertzian pressure of approximately 5000 kg/cm2 and are lubricated by an oil. The composite effect of peripheral speed and viscosity (under a given surface temperature) is necessary to build up a lubricating film with a thickness of 1 micron. The solution is approximate and found by the use of elastohydrodynamic theory.
