Abstract

The article proposes methodology for assessing the power loss in motor thrust bearings, the nodes of box, traction gear transmission. Revealed dependence between the power losses, the diameter of the tire wheel pair and the speed characteristic of the wheel-motor block. The results can be used to assess the technical condition and energy efficiency of traction rolling stock of Railways.
