- Abstract
We present the determining relationship of carriage in non-dimensional form 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, and a few experimental assessments concerning the function of radial bearings with HD lubrication in the case of huge challenging working Due to the very short time of loading radial bearings exposed to shocks and vibrations, of about 0.5-1 ms, we consider only the approaching motion between spindle/axle and bushing on 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.
