Investigation of the influence of the method of lubricating wheel ridges on the operational efficiency of the locomotive

The results of the operation of the comb lubrication devices of various methods of lubrication are presented: contact and liquid. The influence of lubrication technology on the formation of locomotive operational efficiency indicators was studied using the example of a fleet of electric freight locomotives of one series, on which contact and liquid type ridge lubrication devices are installed. The effect-forming factors obtained during the application of comb lubrication devices and the distribution of effects between the Traction Directorate and the Service Company providing maintenance of locomotives with installed comb lubricators are determined.

A comparative analysis of two scenarios with the use of contact and liquid type comb lubricators and a comparison of the main indicators determining the technical and economic efficiency of the use of comb lubricators is carried out.
