Increase the resource and reduce the life cycle cost locomotive wheelset

Abstract

The paper presents the results of research on the analysisy of modern technical means and technologies to increase the service life and reduce the cost of the life cycle of a locomotive wheelset. Calculations are performed and the results of technical and economic efficiency of the use of modern innovative comb-smearing devices lubrication (USGL) and plasma hardening devices (SCR) for locomotive wheel pairs, as well as clutch activation devices (UATL), are presented. The practice of operating USGL and UPU devices has shown that the most effective is their joint use with the achievement of a consolidatedого effect on increasing the service life of locomotive wheel bands. Technical and economic calculation of the efficiency of using UATL friction activation devices has shown the economic feasibility of using locomotive coupling activation systems которые обеспечиваю, which provide an increase in the mileage of locomotives between equipment in the conditions of field operation of the locomotive fleet and reduce the cost of building additional points for equipping locomotives with sand.
