Methodology for calculating loads on locomotive bearings

The article offers a method for calculating the loads acting on the motor-armature bearings of traction motors of locomotives with a double-sided gear transmission, which allows to consider constant and variable loads, magnetic adhesion forces and dynamic loads. When determining the force acting on the gear wheel of the traction motor, it is offered to calculate based on the equivalent operating mode of the electric motor of the locomotive. To increase the accuracy of calculations of the load from the initial unbalance of the armature and some unbalance, as well as the dynamic loads on the cantilever part of the shaft, determine through the equivalent speed of the locomotive on the conventional stretch. Using the offered technique, the forces perceived by the motor-anchor bearings of the traction motors of VL11 electric locomotive operated at Sarga-Sabik section of the North-West range of the Russian Railways were determined.
