Research for Lubricant Dynamic Characteristics of the Double Floating-Ring Bearing

摘要

In this paper, lubricant dynamic characteristics in lubricant region of the double floating-ring are researched by using Boundary Element Method. We obtained the distribution of flow field in lubricant and the pressure on the surface of bearing neck, bearing, inner and outer surface of floating-rings at different eccentric. We also compare the efficiency and loading-bearing capacity of double floating-ring bearing with the single floating-ring. The result we obtained has important theoretical meaning and practical value in designing high efficient bearing.
