The high cost of wheels and rails due to wear and rolling contact fatigue is one of the main problems in the railway transport. The values of creepage, sliding distance and wear rate of wheels and rails at rolling of a wheel on the rail greatly depend on geometric characteristics of working profiles of wheels and rails and location of wheels relative to rails. In the present work the functional requirements of various parts of profiles of wheels and rails and dominating kinds of their damage in various operating conditions are considered and a new profile of a wheel and device for fastening of rails are offered.

Высокая стоимость ремонтно-профилактических работ колес, из-за износа и усталостного повреждения является одным из главных проблем на железодорожном транспорте. При качении колеса на рельсе величина относительного скольжения и интенсивность изнашивания колес и рельсов значительно зависят от геометрических особенностей рабочих профилей колес и рельсов и взаимного расположения рельсов относительно колес. В данной работе рассматриваются функциональные требования различных частей профилей колес и рельсов и доминирующие виды их повреждения при различных условиях работы и предложены новые профили колес и устройства закрепления рельсов.
