Abstract

See full text

The invention relates to a method for reprofiling wheelsets (1) rotatably mounted in axle bearing housings (6) on rail vehicles on underfloor wheelset lathes (12; 14) equipped with machining tools, a machine control for the machining tools, drive rollers (15), axial guide rollers (17), measuring rollers (13) as well as clamping devices (21; 22) to engage the axle bearing housings (6). The method is characterised in that the wheelset (1) is lifted off the rail using the drive rollers (15), weighing it in the process, the axle bearing housings (6) are fixed between the drive rollers (15) and the clamping devices (21; 22), an axial guide roller (17) is adjusted to touch the inner side (16) of each of the two wheels (3; 4) of the wheelset (1) and fixed in this position, an additional force (20) is applied to the drive rollers (15), that the actual diameter (8) and the wear profile of each wheel (3; 4) is determined by means of a measuring roller (13), that the smaller actual diameter is determined based on the measurement results and, it having been modified by a specified machining allowance, entered as the nominal diameter (11) into the machine control for the machining tools.
