Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Schleifen der zwei Neigungen aufweisenden Lauffläche, insbesondere von Eisenbahnrädern, mittels 'einer Schleiffläche, die entsprechend der Lauffläche zwei Neigungen hat. Erfindungsgemäß finden bei dieser Vorrichtung zwei ringförmige, mit ihrer Stirnfläche wirkende Schleifscheiben Verwendung, von denen jede zur Bearbeitung einer Neigung bestimmt ist und die in an sich bekannter Weise konzentrisch ineinander gelagert und in der Schleifscheibenachsrichtung gegeneinander verstellbar sind. The invention relates to a device for grinding the two slopes having running surface, in particular of railway wheels, by means of a grinding surface, which has two slopes corresponding to the tread. According to the invention find this Device using two ring-shaped grinding wheels acting with their end face, each of which is intended for processing a slope and which are mounted concentrically one inside the other in a manner known per se and are mutually adjustable in the grinding wheel axis direction.

Die Erfindung gewährt den Vorteil, daß jeder Schleifring· für sich entsprechend seiner Abnutzung angestellt werden kann. Dies ist besonders für die größere, außenliegende Scheibe vorteilhaft/da diese einen stärkeren Nachschliff auszuführen hat.The invention grants the advantage that each slip ring · for itself according to its Wear can be hired. This is especially for the larger, outboard ones Disc advantageous / because it has to be sharpened more heavily.

An sich ist es schon bekannt, zwei Schleifscheiben konzentrisch ineinander und in der Schleif s cheibenachsenrichtung gegeneinander verstellbar zu lagern. Die entsprechende be-, kannte Einrichtung, bei der" die wirksamen Schleifscheibenflächen im rechten Winkel zueinander stehen, dient aber zum Schleifen der äußeren, kreisbogenförmigen Ahrundung mit den. unmittelbar anschließenden geraden Profilstücken an Spurkränzen, insbesondere von Eisenbahnrädern. Bei dieser bekannten Einrichtung wird der Schleifspindelträger bsi der Bearbeitung um den Mittelpunkt der Spurkranzabrundung geschwenkt. Die Anordnung von zwei Schleifscheiben hat bei dieser bekannten Einrichtung in erster Linie den Zweck, die notwendige Schwenkung auf etwa 900 zu beschränken.It is already known per se to mount two grinding wheels concentrically one inside the other and so that they can be adjusted relative to one another in the grinding wheel axis direction. The corresponding known device in which "the effective grinding wheel surfaces are at right angles to one another, however, serves to grind the outer, circular arc-shaped rounding with the straight profile pieces immediately following on wheel flanges, in particular of railway wheels. In this known device, the grinding spindle carrier bsi pivoted about the center of the machining of the flange rounding. the arrangement of the two grinding wheels must be limited to about 90 0 with this known device in the first place the purpose of the necessary pivoting.

Der Erfindungsgegenstand ist in .einer beispielsweisen Ausführungsform, in der Zeichnung dargestellt.The subject matter of the invention is an example Embodiment shown in the drawing.

Auf den konzentrisch ineinander gelagerten und. gegeneinander axial verschiebbaren Schleifscheibenspindeln 1, 2 sind die Scheiben 3,4 befestigt. Die Scheibe 3 trägt Schleif segmentkörper 5, die in die Scheibe 3 eingesteckt sind, während die Scheibe 4 in diese eingesteckte Schleif segmentkörper 6 trägt. Die Schleifsegmentkörper 5 sind im Winkel zu den Schleifsegmientkörpern 6 angeordnet. Dieser Winkel entspricht dem Winkel, in dem die Flächen 7 und 8 des Eisenbahnlaufrades zueinander stehen. Die Schleifsegmentkörper5 arbeiten an der Fläche 7 und die Schleifsegmentkörper 6 an der Fläche 8 des Eisenbahnrades, und zwar gleichzeitig nebeneinander. Das Schleifwerkzeug könnte selbstverständlich auch so am. Rad angesetzt werden, daß .entweder nur die Segmentschleifkörper 5 oder die Segmentschleifkörper 6 an der Lauffläche arbeiten. Die Zeichnung· läßt erkennen, daß die Schleifwerkzeuge 5, 6 im Scheitel des Winkels, unter dem sie zueinander stehen, einander genähert sind, so· daß die beiden Laufflächen 7 und 8 und damit die Gesamtlauffläche des Rades von den Schleifwerkzeugen gleichzeitig bearbeitet wird. Die Schleifspindel ι wird von dem Motor 9 in Umdrehung versetzt. Die Schleifspindel 2 ist auf der Spindel 1 befestigt und wird von dieser mitgenommen, so daß beide Schleifspindeln die gleiche Umdrehungsgeschwindigkeit haben. Die Anstellung der inneren Schleifscheibe 3 mit gekuppeltem Motor erfolgt vom Handrad ι ο und die Anstellung der äußeren Schleifscheibe 4 vom Handrad 11 aus. Bei dieser Anstellung der Schleifscheiben sind die Zahnräder 12 entkuppelt. Wenn beide Schleifscheiben gleichzeitig angestellt werden sollen, werden die Räder 12 gekuppelt, so daß man entweder vom Handrad 10 .oder vom Handrad 11 aus beide Scheiben verschieben bzw. anstellen kann.On the concentrically nested and. axially displaceable against each other Grinding wheel spindles 1, 2 are attached to the disks 3, 4. The disc 3 carries grinding segment body 5, which are inserted into the disc 3, while the disc 4 in this inserted grinding segment body 6 carries. The grinding segment body 5 are at an angle the grinding segment bodies 6 arranged. This angle corresponds to the angle at which the surfaces 7 and 8 of the railway runner are relative to one another. The grinding segment bodies 5 work on the surface 7 and the grinding segment body 6 on the surface 8 of the railway wheel, and at the same time next to each other. The grinding tool could of course can also be attached to the wheel in such a way that either only the segmented grinding media 5 or the segment grinding wheel 6 work on the running surface. The drawing · leaves recognize that the grinding tools 5, 6 at the apex of the angle at which they are to each other stand, are approached so that the two running surfaces 7 and 8 and thus the total running surface of the wheel is machined by the grinding tools at the same time. The grinding spindle ι is set in rotation by the motor 9. The grinding spindle 2 is attached to the spindle 1 and is taken along by this so that both grinding spindles have the same speed of rotation. The employment of the inner grinding wheel 3 with a coupled motor takes place from the handwheel ι ο and the adjustment of the outer grinding wheel 4 from the handwheel 11. With this adjustment of the grinding wheels, the gears 12 are decoupled. if both grinding wheels are to be employed at the same time, the wheels 12 are coupled, so that you can either use the handwheel 10. or move both discs using the handwheel 11 or can employ.
