Research work on water lubricated polymer hydrodynamic bearing

The subject of this article is the conducting of the measurements on water lubricated shaft bearings. The first part of the article contains the description of the test stand, the working conditions, and the bearing specifications. The second part presents the results of the conducted measurements. The author shows the results of the experimental work: the graphs of the coefficient of friction, the pressures in the water hydrodynamic film and the shaft trajectory. The work's essential conclusion is that the water hydrodynamic lubrication is possible - as it is proven.
