| Abstract: | The dimension analysis based on the similarity theory was applied to a radial hydrodynamic lubrication bearing to improve the frictionfactor equation of a sliding bearing. The improved equation on the frictionfactor and the capacity coefficient was obtained by selecting a reasonable similarity module, which established the relationships between the oil film thickness and the frictionfactor, as well as the capacity coefficient. The oil film thickness could be then obtained by the equation. By model tests of a radial hydrodynamic lubrication bearing, the curves on the relationship between the frictionfactor and capacity coefficient, and that between the oil film thickness and the capacity coefficient were also obtained. |
