Abstract

Friction torque and natural running temperature of ‘Light’ type and ‘Extra Light’ type bearings of bore 5 inches have been measured at speeds ranging from 5,000 to 11,000 r.p.m. Loads up to 2,400 lb. were applied at varying incidence of radial to thrust load. Lubrication was by liquid jet at the rate of 6 pints per min. It is concluded that a large proportion of the friction measured under the conditions of lubricant supply adopted in the experiments is attributable to viscous friction in the lubricant. An analysis of the friction torque based on the work of Poritsky, Hewlett, and Coleman (1947)‡ for varying angles of application of load shows no correlation with the experimental results obtained. Estimates of hysteresis loss based on the work of Tabor (1952, 1954) indicate that this factor represents a comparatively small proportion of the total frictional loss of bearings of this type.
