The invention relates to a method for reprofiling wheelsets (1) rotatably supported on rail vehicles in axle bearing housings (6) on underfloor wheel lathes (12; 14), which comprise material-removing machining tools, a machine controller for the machining tools, drive rollers (15), axial guiding rollers (17), measuring rollers (13), and clamping elements (21; 22) for acting on the axle bearing housings (6). The method is characterized in that the wheelset (1) is lifted from the track with the aid of the drive rollers (15) and weighed, the axle bearing housings (6) are fixed between the drive rollers (15) and the clamping elements (21; 22), an axial guiding roller (17) is brought in contact with the inside (16) of each of the two wheels (3; 4) of the wheelset (1) and is fixed in the position thereof, an additional force (20) is applied to the drive rollers (15), the actual diameter (8) and the wear profile of each wheel (3; 4) are determined by means of a measuring roller (13), and the smaller actual diameter is determined based on the measurement results and is input into the machine controller for the machining tools with a specified machining allowance as a desired diameter (11). |
