Calculation of distribution load between rolling bodiesin the roller bearing of the traction motor

The article proposes a method of calculation the load between the rolling bodies of the swinging bearings and the bearings of the traction motor, which makes it possible to have the value of the radial clearance in the bearing, as well as the radial movement of the inner rings relative to the outer one. To determine the load perceived by the most loaded rollers, a solution of the equilibrium equation for internal elements is proposed using simple iterations. The implementation of the method is implemented in the Matlab software package. Using the proposed method, the load distribution between the rollers in the traction motor of the VL11K electric locomotive was calculated. To determine the load acting on the bearing, the “Sarga-Subic” section was selected, which has a mountain profile.
