PROCEDURES TO AVOID DAMAGE FOR FORCED ADJUSTMENTS IN WHEEL PAIRS, ESPECIALLY IN VEHICLE WHEEL PAIRS ON RAILS.

摘要

Procedure to avoid damage by forced adjustments in pairs of wheels, especially in pairs of wheels of vehicles on rails, in which a surface treatment of an axis of the pair of wheels is performed and the pair of wheels is mounted, characterized in that - previously, a displacement or grinding of the axle of the pair of wheels is carried out in its final cylindrical or conical area in at least one step, and - the joint produced is smoothed and / or rounded so that - the surface treatment of the axis of the pair of wheels through a procedure of ion implantation by immersion in plasma in such a way that cold plasma is applied which, under atmospheric pressure conditions, is presented through a reactive gas as a support gas, a powder that It contains sulfur and is a friction coefficient reducer, on the rotating axle of the pair of wheels.
