Description
"Gerät zum Abziehen versenktliegender Kugellager von
Bei einem solchen Gerät müssen die hakenenden der Abziehhaken in
das Kugellager o. dgl. eingreifen
Geräte dieser Art sind an sich bekannt, bei ihnen wird das Eindrücken der Greifklauen der bziehhaken in das Kugellager durch Hebelwirkung der aus mehreren Gelenkteilen bestehenden Abziehhaken bewirkt. Solche mehrteiligen Abziehhaken, deren Greifvermögen auf der Gelenkwirkung ihrer Einzelteile beruht, können natürlich nicht so sicher wirken, wie einteilige Abziehhaken, sie machen auserden die Bauart des Gerätes verwickelter. Devices of this type are known per se, with them the indentation the gripping claws of the pulling hooks in the ball bearing through the leverage of several Joint parts causes existing puller hooks. Such multi-part puller hooks whose Gripping ability based on the joint action of its individual parts can of course not act as safe as one-piece pulling hooks, they make the design of the Device more complicated.
Das Gerät der Erfindung hat einteilige, starre Abziehhaken und damit den Vorteil einer einfacheren und sicherer wirkenden Bauart gegenüber den vorbekannten Abziehgeräten. The device of the invention has one-piece, rigid puller hooks and thus the advantage of a simpler and safer-looking design compared to the previously known Pulling devices.
Bei dem Abzieher oder Auszieher der Erfindung werden die am Körper des Abziehgerätes schwenkbar hängenden, einteiligen Abziehhaken durch eine als Gewindemutter ausgebildete Spreizscheibe auseinandergedrückt, welche hinter den Greifklauen an den Abziehhaken angreift und letztere unmittelbar in die Kugelbahn des äusseren Kugellagerringes oder eine sonstige Rille oder hinter einen Vorsprung des abzuziehenden Gegenstandes drückt. Dabei stützt sich die zentrale Druckschraube des Gerätes gegen das Kopfende der iíelle, welche das Kugellager o. dgl. trägt. In the puller or extractor of the invention, the on the body of the puller with a swiveling, one-piece puller hook by means of a threaded nut trained expansion disc pushed apart, which behind the gripping claws the pulling hook engages and the latter directly into the ball track of the outer one Ball bearing ring or some other groove or behind a projection of the to be withdrawn Pushes the object. The central pressure screw of the device supports itself against this the head end of the iíelle, which carries the ball bearing or the like.
Auf der Zeichnung ist das neue Abziehgerät in einem Ausführungsbeispiel dargestellt. In the drawing, the new pulling device is in one embodiment shown.
An dem Körper 1 des Abziehgerätes sind in beliebiger Zahl die Abziehhaken 2 schwingbar oder beweglich aufgehängt. Die Abziehhaken werden von den Bolzen 3 der Querträger 4 gehalten, welche in einer Führung des Körpers 1 verschiebbar sina. Any number of puller hooks are on the body 1 of the puller 2 suspended swinging or moveable. The extractor hooks are held by the bolts 3 the cross member 4 held, which sina in a guide of the body 1 slidably.
Diese Führung wird von dem Flansch 5 unu der Butter 6 gebildet. In dem Körper 1 des Abziehers dreht sich die Druckschraube 7. Die Enden der Abziehhaken 2 sind zu Greifklauen 8 ausgebildet, welche in das von der iielle 9 abzuziehende Kugellager lo eingreifen.This guide is formed by the flange 5 and the butter 6. In The pressure screw 7 turns on the body 1 of the puller. The ends of the pulling hooks 2 are designed to form gripping claws 8, which are inserted into the 9 to be withdrawn from the iielle Ball bearing lo engage.
Dieses für die sichere Wirkung des Abziehgerätes entscheidende, wirksame Eingreifen der Klauenenden 8 der Abziehhaken 2, wird durch eine als Gewindemutter ausgebildete Spreizscheibe 11 bewirkt, die sich auf dem Körper 1 des Abziehgerätes dreht. Durch Bewegung dieser hbziehscheibe zu den Klauenenden der Abziehhaken hin, werden letztere auseinandergedrückt. This, which is decisive for the safe operation of the puller, is effective Engaging of the claw ends 8 of the puller hook 2 is made by a threaded nut formed expanding disc 11 causes, which is on the body 1 of the puller turns. By moving this pulling disc towards the claw ends of the pulling hooks, the latter are pushed apart.
Das mit dem Eindrücken der Klauen in das abzuziehende Kugellager o. dgl. verbundene Auseinanderdrücken der Abziehhaken geschieht mit ausserordentlich grosser Wirksamkeit, da es durch Drehung einer Gewindemutter geschieht und deren Axialverschiebung auf zu letzterer schwach geneigten Rückenbahnen der Abziehhaken erfolgt.The result of pressing the claws into the ball bearing to be withdrawn or the like. Like. Associated pushing apart the puller hooks happens with extraordinary great effectiveness because it is done by turning a threaded nut and its Axial shift on the back tracks of the pulling hooks that are slightly inclined to the latter he follows.
