Seizure Time of Journal Bearing with Varying Parameters for Different Materials

Abstract

The current trend of modern industry is to use hydrodynamic journal bearings machineries rotating at high speed and carrying heavy rotor loads. When a bearing operates at high speed, the heat generated due to large shearing rates in the lubricant film raises its temperature. The study is performed to find out optimum model based on three parameters namely Internal radius (Ri), Length of Journal(L) and Clearance(C) for different materials i.e., Cast Nylon, Gun metal, Steel and Brass. Equations are derived for the rate of heat generation and for the rate of heat dissipation in terms of factors of construction and operation. Three dimensional models are created in CATIA and transient thermomechanical analysis is performed for every model in ANSYS. Seizure times of the journal in the bearing are noted to find out optimum parameter to ensure the optimum material for Journal Bearing.
