Hardening the rolling surface of the wheels bandage after mechanical treatment

Abstract

Article describes calculated argumentation of the striker sealing surface, in the form of the two cylinders with parallel axes model of loading, having an effect on the rim surface of the wheel pairs of rolling-stock. There has been presented a calculation variant of the depth of hard running surfacing of the rolling-stock wheel pairs. Installation of deep hardening of rolling surfaces of wheel sets allows the special striker to create certain forces on the rolling surface of the wheel rim, to deform the surface layer to a certain depth, thereby increasing the hardness of the deformed surface. The article presents the technology for hardening the wheel running surface by loading the surface of the wheel set bandage, by means of the deep hardening installation with the creation of strain stress in the surface layers for several combinations of tensile strength σB and velocity σT of various bandage materials.
