PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft ein Verfahren und die Maschine hierzu, um die zylindrische, kegelförmige, ballige oder hohle Außenfläche von Rollen so zu schleifen, daß die Außenfläche konzentrisch zur Bohrung der Rollen wird.The present invention relates to a method and the machine for this purpose, in order to produce the cylindrical, to grind conical, convex or hollow outer surface of rollers so that the outer surface becomes concentric to the bore of the rollers.
Das Wesen der Erfindung liegt darin, daßThe essence of the invention is that
die Rolle mit Hilfe von zwei in Berührung mit der Wand der Bohrung stehenden Führungskanten an eine umlaufende Schleifscheibethe roller by means of two leading edges in contact with the wall of the bore to a rotating grinding wheel
derart gehalten wird, daß den Rollen, wie an sich bekannt, durch die Schleifscheibe eine Drehbewegung um die Führung erteilt wird.is held in such a way that the rollers, as known per se, by the grinding wheel a Rotational movement is issued around the guide.
Das in den Fig. ι bis 3 der Zeichnung veranschaulichte Ausführungsbeispiel möge dies näher veranschaulichen.That illustrated in Figs. Ι to 3 of the drawing Embodiment may illustrate this in more detail.
Fig. ι zeigt in schematischer Darstellung die Einrichtung zum Schleifen von Rollen mit
Bohrung in Vorderansicht,
Fig. 2 in Seitenansicht,Fig. Ι shows a schematic representation of the device for grinding rollers with a bore in a front view,
Fig. 2 in side view,
Fig. 3 in Draufsicht nach geschnittener Schleifscheibe.Fig. 3 in plan view after a cut grinding wheel.
Die Schleifscheibe α wird mittels der Welle b The grinding wheel α is by means of the shaft b
in Richtung des eingezeichneten Pfeiles angetrieben. Die zu schleifende Rolle wird von einer geeigneten festen Unterlage d getragen und sitzt lose auf dem ruhenden Dorn f, welcher zweckmäßig gegenüber der Scheibe a nachgestellt werden kann und die Rolle c gegen die Schleiffläche der Scheibe α hält.driven in the direction of the arrow. The roller to be ground is carried by a suitable solid base d and sits loosely on the resting mandrel f, which can be adjusted appropriately in relation to the disk a and holds the roller c against the grinding surface of the disk α.
Dabei berührt die Rolle c die Schleiffläche nach einer Mantellinie.The roller c touches the grinding surface after a surface line.
Die in die Richtung dieser Mantellinie fallenden Bewegungskomponenten der Berührungspunkte bringen dann eine Schleifwirkung in dieser Richtung hervor, die senkrecht dazu liegenden Komponenten dagegen eine Drehung der Rolle um den Dorn f gemäß dem eingezeichneten Pfeil.The movement components of the points of contact falling in the direction of this surface line then produce a grinding effect in this direction, whereas the components perpendicular to it produce a rotation of the roller around the mandrel f according to the arrow shown.
Bedingung für das Zustandekommen beider Wirkungen ist, daß die Berührungsmantellinie weder auf einem Durchmesser der Schleifscheibe noch in der Mitte einer Sehne liegt. Je nach der Einstellung zwischen diesen beiden Grenzlagen kann mehr die eine oder die andere der beiden Wirkungen hervorgekehrt werden.The condition for the occurrence of both effects is that the contact envelope line is neither on a diameter of the grinding wheel nor in the middle of a chord. Depending on the setting between these two limit positions, more one or the other other of the two effects can be produced.
Würde nun als Führung für die Rolle gemäß Fig. 4 ein einfacher zylindrischer Stift verwendet werden, so würde unter Wirkung der schnellen Umdrehung der Rolle ein Pendeln derselben um den festen Stift f eintreten, und die Rolle wird zwischen der ausgezogen und der gestrichelt gezeichneten Stellung hin und her pendeln, so daß die diesen beiden Stellungen entsprechenden Berührungsmantellinien zwischen Stein und Rolle eine andere Entfernung vom Stift f haben als im Falle der Stellung nach Fig. 3.If a simple cylindrical pin were to be used as a guide for the roll according to FIG. 4, the rapid rotation of the roll would cause it to oscillate around the fixed pin f , and the roll would move between the extended position and the position shown in dashed lines and commute so that the contact surface lines corresponding to these two positions between stone and roller have a different distance from the pin f than in the case of the position according to FIG. 3.
Gemäß vorliegender Erfindung wird daher der Rolle dadurch eine sichere Auflage gegeben, daß sie die Führung f nach zwei Linien berührt, die nach Fig. 3 z. B. dadurch erzeugt gedacht sind, daß die vordere Fläche des ursprünglich zylindrischen Stiftes f abgeflacht ist. Die Rolle liegt also an den Kan-According to the present invention, therefore, the role is given a secure support in that it touches the guide f after two lines that are shown in FIG. B. are thought generated by the fact that the front surface of the originally cylindrical pin f is flattened. So the role is up to the
