Abstract:
Journal bearings are used on a variety of different rotating and reciprocating machines to support shafts that are rotating inside a bearing. In contrast to anti-friction type bearings where the primary mechanism is rolling action of contacting components, journal bearings operate by supporting the load of the shaft on a pressurized oil film.Approach of this paper is to describe static and dynamic loads and dynamic characterizes that effect on fluid film thickness and enhance tilting pad bearing model by including nonlinear pivot flexibility for rocker, spherical, and flexure type pivots
