Description

Maschine zum Schleifen von Rollen zwischen zwei umlaufenden ebenen Schleifscheiben. Die Erfindung richtet sich auf eine Maschine zum Schleifen von Rollen zwischen zwei umlaufenden ebenen Schleifscheiben. Man hat derartige Maschinen bisher entweder so eingerichtet, daß die Rollen in einem um die Scheibenachse drehbaren Käfig zu einer anderen Umfangsgeschwindigkeit gezwungen werden, als der Relativgeschwindigkeit der sie berührenden Stellen der Schleifscheiben entspricht, oder man ließ die Werkstücke, durch Schleuderkraft nach außen getrieben, an einem den Spalt zwischen der Scheibe begrenzenden Führungsring abrollen, der mit der unteren Scheibe fest verbunden war.Machine for grinding rolls between two circumferential levels Grinding wheels. The invention is directed to a machine for grinding Roll between two rotating flat grinding wheels. You have machines like that so far either set up so that the rollers can be rotated around the disk axis Cage are forced to a different peripheral speed than the relative speed corresponds to the points of contact on the grinding wheels, or the workpieces were left, driven outwards by centrifugal force, at one of the gap between the disc Unroll the limiting guide ring that was firmly connected to the lower disk.

Die Erfindung geht von der zuletzt geschilderten Maschinengattung aus und kennzeichnet sich im wesentlichen dadurch, daß die Werkstücke zum Schleifen ihrer ebenen und zylindrischen Rollenflächen in Aussparungen eines Käfigs untergebracht sind, der selbst an dem Führungsring abrollend die Rollen derart führt, daß diese außer der Bewegung um die Scheibenachse eine kreisende Bewegung um die Käfigachse erfahren.The invention is based on the type of machine described last and is essentially characterized by the fact that the workpieces for grinding their flat and cylindrical roller surfaces in recesses of a Cage are housed, which even on the guide ring rolling the rollers in such a way leads to a circular motion in addition to the motion around the disk axis about the cage axis.

Auf diese Weise wird mit einfachen Mitteln und geringem Kraftbedarf eine recht günstige Relativbewegung zwischen den Rollen und den Schleifscheiben erzielt.In this way, with simple means and little effort a quite favorable relative movement between the rollers and the grinding wheels achieved.

Auf der Zeichnung ist die Erfindung in einer Ausführungsform schematisch veranschaulicht, durch einen Querschnitt Abb. i und eine Aufsicht, bei abgenommener oberer Scheibe, Abb. a.The invention is shown schematically in one embodiment in the drawing illustrated by a cross-section Fig. i and a plan view, with removed upper disc, fig. a.

Zwischen den Schleifscheiben a, b sind die Käfige c angeordnet, die in Löchern d die Werkstücke, nämlich die Rollen e, aufnehmen und führen. Beim Arbeiten der Maschine wälzen sich die Käfige c an dem Führungsring f ab, der getrennt von den Schleifscheiben angeordnet wird, aber auch mit einer der Schleifscheiben angeordnet werden kann. Die Drehyng der Scheiben a, b findet vorzugsweise in entgegengesetzter Richtung statt.Between the grinding wheels a, b, the cages c are arranged, which receive and guide the workpieces, namely the rollers e, in holes d. When the machine is working, the cages c roll on the guide ring f, which is arranged separately from the grinding wheels, but can also be arranged with one of the grinding wheels. The rotation of the disks a, b preferably takes place in the opposite direction.

Die Rollenwerkstücke werden je nach ihrer Lage in den Löchern d auf ihrer zylindrischen Umfläche oder auf ihren ebenen Stirnflächen bearbeitet. Durch kreisrunde Ausbildung der Löcher gelingt es auch, die Umfläche der Rollenschwach ballig zu schleifen, dadurch, daß die Rollen eine Eigendrehung um ihre senkrechte Mittelachse erfahren mit der Wirkung eines stärkeren Abschliffes nach den Enden zu. Die Käfige c brauchen nicht kreisrund zu sein; sie können auch längliche Gestalt besitzen und auf einem Führungsring mit Ausbuchtungen rollen.The roll workpieces are depending on their position in the holes d on their cylindrical surface or machined on their flat end faces. By circular formation of the holes also succeeds in making the area around the rollers weak to grind spherical, in that the rollers rotate their own way around their vertical Center axis experienced with the effect of a stronger abrasion towards the ends to. The cages c do not need to be circular; they can also be elongated in shape own and roll on a guide ring with bulges.

PATENTANSPRÜCHE: i. Maschine zum Schleifen von Rollen zwischen zwei umlaufenden ebenen Schleifscheiben, bei der eine Abrollbewegung der Werkstücke an einem äußeren, den Scheibenspielraum begrenzenden Führungsring durch Schleuderkraft die Schleifbewegung der Werkstücke zwischen den Scheiben hervorbringt, ,. dadurch gekennzeichnet, daß die Werkstücke (e) zum Schleifen ihrer ebenen und zylindrischen Rollenflächen in Aussparungen (d) eines Käfigs (c) angeordnet sind, der selbst an dem Führungsring (f) abrollend die Rollen derart führt, daß diese außer der Bewegung um die Scheibenachse eine kreisende Bewegung um die Käfigachse erfahren. a. Rollenschleifmaschine nach Anspruch i, dadurch gekennzeichnet, daß die Aussparungen -(d) des Käfigs rund ausgebildet sind, um eine Eigendrehung der Rollen um eine lotrechte Achse zu ermöglichen und dadurch einen schwach Balligen Rollenschliff zu erreichen. PATENT CLAIMS: i. Machine for grinding rolls between two revolving flat grinding wheels, in which a rolling movement of the workpieces on an outer guide ring that delimits the disk clearance produces the grinding movement of the workpieces between the disks by centrifugal force,. characterized in that the workpieces (e) for grinding their flat and cylindrical roller surfaces are arranged in recesses (d) of a cage (c) which itself guides the rollers rolling on the guide ring (f) in such a way that, in addition to moving about the Disc axis experience a circular motion around the cage axis. a. Roller grinding machine according to claim i, characterized in that the recesses - (d) of the cage are round in order to enable the rollers to rotate themselves about a vertical axis and thereby to achieve a slightly convex roller grinding.
