Investigations on influence of groove shapes for the journal bearing in high-speed and heavy-load press system
Abstract
Purpose
The purpose of this study is to investigate the hydrodynamic characteristics of journal bearings in a high-speed and heavy-load press system by considering thermal influence and cavitation.
Design/methodology/approach
A proper and effectual computational method is presented for steady-state analysis of fluid interaction in a rotor-bearing press system by combining computational fluid dynamics techniques.
Findings
The influences of eccentricity ratio, rotational speed and oil-film thickness on the hydrodynamic behavior of the journal bearing are studied.
Originality/value
The computational method can be used for creating a precise lubrication design for a journal bearing of a lubrication system.
