Two Phase Flow Pattern of Injection Lubrication in High Speed Bearings

Abstract

Abstract. In this paper, the study of Numerical analysis of bearing lubrication flow field is presented. When the lubricating oil flows into the bearing, the fluid distribution in the radial direction assumes a gradient state under the influence of the centrifugal force at high speed. Through the experiment, it is recommended to be more than the angle of 45 0 of the nozzle lubrication. With variable contact radius, the fluid gathered more concentrated, which is not conducive to the rolling lubrication and cooling. When R arc of contactor is not 0mm, the contact wear section is shown the horizontal elliptical shape, and as the radius decreases, the elliptical axis increases, and more requirements of bearing lubrication conditions in this case.
