Abstract
The invention relates to a process for the production of load-dependent, wear-resistant, wire, rope and/or wire cable running surfaces moved in rotation, in particular surfaces of wire pulling drums in wire pulling machines or similar transport rollers or drums, said process involving skin hardening in hardness tracks dimensioned to suit the component and the application, whereby energy is applied track by track in propotioned amounts by means of unconventional hardness processes, such as laser hardening or electron beam hardening processes. According to the invention, the hardness tracks (5) in this process are inclined in parallel at an angle (4) of < 90 degrees to the axis of rotation of the wear-subjected wire, rope and/or wire rope running surface, and said hardness tarcks (5) are offset about the circumference of the wire, rope and/or wire rope running surfaces in such a way that a controlled heat effect is achieved as symmetrically as possible on the said runningsurfaces.
