Abstract

In this research paper, the theoretical performance of a circular offset bearing is evaluated. The objective of this paper is to discuss the effects of eccentricity ratios and micropolarity parameters on the static and dynamic characteristics of an offset bearing with respect to micropolar lubrication. The modified Reynolds' equation for a dynamic state is solved using the finite-element method and Galerkin technique. The performance of an offset bearing is computed for a chosen range of eccentricity ratios (0.4–0.6) and for a length–diameter ratio (2.4). Enhancement in the performance of a bearing system is achieved in terms of increasing load and decreasing whirling at the higher values of eccentricity and offset especially at higher micropolarity.
