The Dynamic Circumferential Pressure Distribution to the Sliding Radial Bearing Working under Hard Shocks

Abstract

This paper presents a few theoretical assessments concerning the function of radial bearings with HD lubrication in the case of huge challenging work. We consider only the approaching motion between the spindle/axle and bushing in the direction of the center line, without the rotation of the spindle/axle (the case of the non-rotating bearing), so that the effect of the lubricant expulsion be prevalent in the achieving of the self carrying film. We present the determining relationship of circumferential pressure distribution, squeeze force coefficient γ for narrow radial bearings exposed to shocks and vibrations, as well as the determining relationships of the lubricant minimum thickness in relation to the dynamic loading.
