Methods of Testing Gearboxes of Rail Vehicles

Abstract:

The article deals with the various methods of testing gearboxes of rail vehicles such as tram, metro, suburban unit EMU (Electric Multiple Unit). Further deals with determination of the load test parameters, the methodology for measuring of monitored magnitude and result evaluation. Some gearboxes have been designed for extreme operating temperatures ± 40°C. In the article are described the main types of tests performed on gearboxes of rail vehicles and their results on specific types of gearboxes. Tests include the following methods: verification of assembly accuracy, sealing test against leak of oil, sealing test against ingress of water (water fog) at runtime of gearbox, sealing test gearbox against ingress of water under pressure at rest, long duration test on-load (runtime test) with variable load spectrum, test in mode "Cold climate test", contact pattern gears (application of modification).
