Procedure for the re-profiling of wheel profiles on wheels of railway bicycle sets, consisting of running and track-crossing surfaces

摘要

The invention concerns a method of reprofiling the wheel profile surfaces (5), composed in each case of wheel-tread surface (2) and wheel-flange surface (33), of railway wheel sets (10) by turning. The wheel sets (10) are rotationally driven about a centre axis (4). In this method, a measuring surface (8) is turned on the wheel profile surfaces, whereupon the turning tools (12), after the diameters of the measuring surfaces are measured, are adjusted as a function of this measured result and of the wear depths perpendicular to the centre axis (4) towards the centre axis in such a way that they have produced new profiles of the same diameter on the reprofiled wheel set after the reprofiling is complete. To avoid the rolling-in of chips in such machines during the machining and to avoid the dismantling of axle boxes, it is proposed that the wheel set to be reprofiled be accommodated and fixed in the dismantled state for the drive at its axle boxes (24) and that it be rotationally driven by at least one friction roller (29), the reprofiling of the new profiles being effected first of all outside the contact surfaces of friction roller/wheel and subsequently in the remaining area of the profile.
