The purpose of this study is to determine the effect of the radial clearance on the load between the rolling elements in the bearing of the locomotive traction motor. A method has been developed for calculating the distribution of the load between the rolling elements of a roller bearing of a traction motor, which makes it possible to take into account the radial clearance in the bearing, as well as the radial movement of the inner ring relative to the outer ring. To determine the load perceived by the most loaded roller, it was proposed to solve the equilibrium equation for the inner ring of the bearing using the method of simple iterations. The implementation of the method was carried out in the Matlab software package. Using the proposed technique, the load distribution between the bearing rollers in the locomotive traction motor was calculated. To determine the load acting on the bearing, the Sarga – Sabic section was selected at the Sverdlovsk railroad test site, which has a complex rail track profile with large slopes. Analysis of the results showed that with an increase in the radial clearance of the bearing, the load on the most loaded roller increases.
