TRIBOLOGICAL WEAR OF WHEEL RIMS IN RAIL VEHICLES IN OPERATING CONDITIONS
Journal Title: Tribologia - Year 2016, Vol 268, Issue 4
Abstract
Wheel sets as elements determine the reliability and safety in railway traffic demand ensuring high technological and quality standards at the stage of production and exploitation. Not satisfying these conditions may result in, among others, premature wear of wheels in the wheel sets, in turn a shortening between-repair running periods and increasing the exploitation costs of rail vehicles. The authors, based on carried out tests, analysed the influence of not satisfying proper parameters of heat treatment of wheel rims on tribological wear on their surface. This especially concerns abrasive wear of wheel rims and damages of the spalling type on the wheel thread surface in wheel sets.<br/><br/>
