OIL FILM PRESSURE IN HYDRODYNAMIC JOURNAL BEARIN...

hydrodynamic journal bearings is essential to machine design. Oil film pressure is one of the key operating parameters describing the operating conditions in hydrodynamic journal bearings. Measuring the oil film pressure in bearings has been a demanding task and therefore the subject has been studied mainly by mathematical means.

US5320431A - Lubrication groove arrangement for a journal ....

The invention is an improvement in a machine having a bushing-type journal bearing and a bearing-supported component relatively rotatable one to the other. The bearing has a surface contacting the component and at least one lubrication groove formed in such surface. The improvement comprises a plurality of lubrication grooves spaced along the surface and defining first and second groove sets.

Experimental and numerical study on water-lubricated ....

Purpose – Water-lubricated rubber bearing is one of the most appropriate bearings for underwater use. The most popular design used widely today is the straight fluted rubber bearing. The special configuration leads to partial hydrodynamic lubrication and low load capacity. A new bearing bush structure with two cavities which is favorable for constructing continuous hydrodynamic lubrication ...

that distinguish the two basic bearing categories – ball bearings and roller bearings. There is a groove called the ball path on both the inner and outer races of ball bearings in which the balls roll. For roller bearings, the rollers roll on the flat surface of each race. This surface is called the roller path.

On the Design of Tilting-Pad Thrust Bearings - orbit.dtu....

Parallel-step bearings theoretically have smaller friction coefficients than tilting-pad bearings. A design of a tilting-pad bearing is suggested which combines the benefits of the two types of bearings in a tilting-pad bearing with inlet pockets. This design results in a substantial reduction of the friction loss.

The Lubrication of Bearings — Principles of the Oil Film ....

This pressure is due to the adhesive property of the oil and to the motion of the revolving journal, forcing the oil into a clearance space of decreasing thickness; thus forming an oil wedge (H—Fig. 5), which is one of the requisites in the lubrication of frictional bearings.
