THE EFFECT OF ERRORS IN SETTING BEARING HOUSINGS OF A THREE-BEARING SHAFT ON THE BASIC RATING LIFE OF A BEARING SYSTEM

摘要

A system consisting of a shaft and three bearings is statically undetermined. In line with external loads, shaft rigidity and bearing rigidity also influence the scale of loading of supports (i.e. bearings). It is taken into consideration that fulcrums of a conventional shaft line (determined by inner bearing rings) may not be located along one straight line due to errors in setting of bearing cases.
