The Elastohydrodynamic Lubrication Analysis of Starved Water-Lubricated Rubber Bearing

Abstract:

Water becomes a good application prospect lubricant for its low cost, energy saving, good safety and environment friendly characteristic. A bearing microscopic surface pitting lubrication model was established, the water condition of it was introduced and the effects of the speed and the load on the film thickness were discussed.The result show that with the provided water film thickness increases, the film thickness also increases. However, when it is added to a certain degree, the film thickness will no longer change, there exists a critical point. Under water-lubricated conditions, the film thickness and minimum film thickness are increased greatly with the increase of speed and decreased greatly with the increase of load in both staved and full water conditions.
