Abstract
This paper describes details of a solution to the finite journal bearing problem, including the effects of elastic distortions in the bearing liner. Solutions for the particular case of a bearing of length to diameter ratio of 1, outside to inside diameter ratio of 1·3, and Poisson's ratio of 0·4 have been obtained and the results are compared with experimental results obtained with a Delrin plastic bearing. Good agreement between theory and experiment has been obtained.
The theory, which is applicable to soft shell bearings supported in a rigid housing, predicts that:
the ratio of the peak pressure to the average pressure is reduced; the bearing stiffness is reduced; the minimum film thickness for a given load is reduced by elastic distortions at eccentricity ratios less than unity; and the friction is reduced.
