Abstract

This paper is concerned with a theoretical analysis of two types of double film bearings; namely, circular-circular and rectangular-rectangular, lubricated with incompressible fluid.
In order to have a clear understanding of the performance characteristics of these two types of double film bearings, the performance characterist-ics that include load carrying capacity, flow rate, power, and stiffness of single film circular and rectangular bearing is presented.
The results revealed that, the given mathematical model can be used in the design of a double film bearings.
A comparison between the performance characteristics of circular-circular and rectangular-rectangular double film bearings are presented, assuming that they have the same area and the same supply pressure.
