An external load applied to a rolling bearing is distributed among the rolling elements. Several experimental methods to determine the load distribution of rolling bearings have been proposed so far. Their methods, however, can not provide dynamic load distributions while rolling elements make one revolution along the raceway. The objective of this study is to establish a more direct method than the other ones for determining rolling element load distributions dynamically. The method herein proposed provides the measurement of strains of rollers developed under an applied load by using an optical fiber strain sensor mounted on a roller of a measuring cylindrical roller bearing. This paper presents the method for determination of dynamic load distributions.
