Embodiment Construction

[0051] figure 1 The wheel set 1 shown in is composed of an axle 2 and two discs 3 and 4 . In the assembled state, the wheel set 1 is rotatably seated with its journal 5 in a bearing housing 6 of a rail vehicle (not shown).

[0052] figure 2 A cutout of the wheel profile 7 is shown, by which the wheels 3 and 4 are each delimited on their outer circumference. The wear profile, which occurs after a certain period of use of the wheelset 1 , is indicated here by the line 8 . This worn profile 8 is the actual profile and it is known that material is rolled out from the region of the measuring ring, which is pushed towards the side of the rim 9 and the outer side 10 of the wheel profile 7 .

[0053] Indispensable for the reshaping, the actual contour 8 is removed and a theoretical contour 11 which meets the requirements of the reshaping of the wheelset 1 is regenerated. In order to determine the actual contour 8 , the free wheel lathe has a measuring roll 13 which is also used t...

Abstract

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.

Description

technical field [0001] The invention relates to a method for reshaping a wheel set rotatably housed in a bearing housing of a rail vehicle on a non-dropping wheel lathe having machining tools for machining, Machine controls for processing tools, drive rollers, axial guide rollers, measuring rollers and tensioning devices for snapping onto bearing housings. Background technique [0002] EP0201619B1 describes a method for material-saving correction of the profile of a rail wheel using a cutting process. In this known method, certain regions of the contour have deviations from the theoretical contour due to material wear on the friction surfaces and / or the rim, the method is characterized in that a contour with relatively little wear is determined area, where the deformation process takes place, whereby the material in this area is extruded and flows towards the lower-lying areas, thereby at least partially filling the most worn areas with material, after which the radial cond...
