Description
Vorrichtung zum Feststellen eines gegenüber einer Welle mit Hohlkehle verdrehbaren Teiles an dieser Welle. Gegenstand vorliegender Erfindung ist eine Vorrichtung zum Feststellen eines gegenüber einer Welle mit Hohlkehle verdrehbaren Tei les an dieser Welle, die sich dadurch aus zeichnet, dass der festzustellende Teil eine Eindrehung aufweist, in welche eine im er wähnten Teil radial angeordnete Gewinde bohrung mündet, und dass ein elastischer Arretierkörper vorgesehen ist, der reit seinem Hals in der Gewindebohrung und mit seinen beiden Lappen in der Eindrehung liegt und die Welle bei ihrer Hohlkehle mit den Lap pen teilweise umfasst,
wobei die der Welle zugekehrte Fläche des elastischen Arretier körpers im entspannten Zustand desselben einen Krümmungsradius besitzt, der kleiner ist als der Radius der Wellenhohlkehle und dass endlich zum Feststellen des verdreh bat-en Teiles an der Welle eine Schraube vorgesehen ist, die in der Gewindebohrung angeordnet und bestimmt ist, beim Fest stellen gegen den elastischen Arretierkörper gepresst zu werden und dabei dessen Lappen zu spreizen und sich dadurch anderseits ge gen Lockerwerden selbst zu sichern.
Der Erfindungsgegenstand ist in der Zeich nung in einem Ausführungsbeispiel in An wendung auf eine Noniusscheibe an einer Werkzeugmaschine dargestellt.
Es zeigt Fig. 1 einen Längsschnitt und Fig. 2 einen Querschnitt durch die Vor richtung in grösserem Massstab.
1 ist die Noniusscheibe an einem Dreh banksupport. Diese weist eine Eindrehung 2 auf, in die radial eine Gewindebohrung 3, die eine Schraube 7 aufweist, mündet. In diese Eindrehung ist der elastische Ar retierkörper 4 mit seinen die Wellenhohl kehle 6 teilweise umfassenden Lappen ein gesetzt, wobei der Hals des Körpers 4 in die Gewindebohrung 3 ragt. Im entspannten Zustand ist der Krümmungsradius der der Welle zugekehrten Fläche des Körpers 4 kleiner als derjenige der Hohlkehle der Welle.
In diesem Zustand wird die Noniuascheibe 1 über die Welle 5 geschoben, bis ihre Ein drehung 2 über die Wellenhohlkehle 6 zu stehen kommt; durch Anziehen der Schraube 7 kann sodann der Körper 4 mit seinen den Hohlkehlengrund der Welle teilweise um fassenden Lappen fest angepresst werden, wo durch die Noniusscheibe gegenüber der Welle arretiert und die Schraube 7 zugleich ge sichert ist.
Device for locking a part on this shaft which can be rotated with respect to a shaft with a groove. The subject of the present invention is a device for locking a relative to a shaft with a groove rotatable Tei les on this shaft, which is characterized in that the part to be fixed has a recess into which a thread bore arranged radially in the part mentioned opens, and that an elastic locking body is provided which rides its neck in the threaded hole and with its two lobes in the recess and partially surrounds the shaft at its groove with the lap,
The surface of the elastic locking body facing the shaft, in the relaxed state, has a radius of curvature that is smaller than the radius of the shaft groove and that finally a screw is provided for fixing the twisted part on the shaft, which is arranged in the threaded hole and it is intended to be pressed against the elastic locking body when it is fixed and to spread its flap in the process, thereby securing itself on the other hand against loosening.
The subject of the invention is shown in the drawing in an exemplary embodiment in application to a vernier disk on a machine tool.
It shows Fig. 1 a longitudinal section and Fig. 2 a cross section through the device on a larger scale.
1 is the vernier disk on a rotary bench support. This has a recess 2 into which a threaded bore 3, which has a screw 7, opens radially. In this recess of the elastic Ar retierkörper 4 is set with its hollow throat 6 partially encompassing tabs, wherein the neck of the body 4 protrudes into the threaded hole 3. In the relaxed state, the radius of curvature of the surface of the body 4 facing the shaft is smaller than that of the groove of the shaft.
In this state, the vernier disk 1 is pushed over the shaft 5 until its A rotation 2 comes to stand on the shaft groove 6; by tightening the screw 7, the body 4 can then be firmly pressed with its fillet base of the shaft partially to grasping tabs, where locked by the vernier washer against the shaft and the screw 7 is secured at the same time ge.
