Numerical Calculation Analysis of Structural Parameters of Water-Lubricated Thrust Bearing

Abstract:

The affect of the thrust pad inclination and ratio of length to breadth (L/B) on the lubricity of a water-lubricated thrust bearing is studied in numerical method. The research results indicate that when the elastic deformation is considered, the distribution of both water film thickness and pressure presents to be paraboloid. With the increase of thrust pad inclination, both maximum water-film pressure and the friction coefficient increase, and the minimum water-film thickness decreases first and then increases; when the L/B increases in the range of 1~2, both maximum water-film pressure and the friction coefficient increase, but the minimum water-film thickness decreases.
