Testing of a Large Adjustable Hydrodynamic Journal Bearing
The design and testing of two novel adjustable hydrodynamic journal bearings are outlined. Each was designed to replace a conventional bearing in a large marine gearbox. They were tested in a land based rig and their performances compared with that of the conventional bearing. The novel bearings demonstrated the ability to suppress journal orbits, to reposition the journal centre in any directi...
متن کاملModelling of Hydrodynamic Journal Bearing in Spatial Multibody Systems
The model of a three dimensional journal bearing with hydrodynamic lubrication is herein presented. This model is suitable for embodiment into the equations of spatial multibody systems. Both rotational and squeeze effects together with tilting effect have been taken into account. Moreover a simplified model of friction has been also reported. The proposed methodology has been applied to an exa...
متن کاملOn the Steady-State Performance Characteristics of Finite Hydrodynamic Journal Bearing under Micro-Polar Lubrication with Turbulent Effect
The objective of the present paper is to theoretically investigate the steady-state performance characteristics of journal bearing of finite width, operating with micropolar lubricant in a turbulent regime. In this analysis, the turbulent shear stress coefficients are used based on the Constantinescu’s turbulent model suggested by Taylor and Dowson with the assumption of parallel and inertia-le...
متن کاملanalysis of performance characteristics of two-lobe journal bearing with micropolar lubricant
in this paper, static performance characteristics for a finite lenght two-lobe journal bearing lubricated with micropolar fluid is studied. using finite element method, steady-state film pressure is obtained by solving modified reynolds equation, based on micropolar lubrication theory. with the help of film pressure in bearing, the static performance characteristics in terms of load carrying ca...
متن کاملThermo-elasto-hydrodynamic (TEHD) analysis of oil film lubrication in big end bearing of a diesel engine
Nowadays, due to the increasing power of diesel engines, especially heavy duty diesel engines, and increasing gas pressure inside the combustion chamber, the forces acting on the engine bearings have dramatically raised. On the other hand, becaus eof the competition in the market, it is necessary to increase the engine bearing life and reduce its failure as much as possible. The engine bearings...
