Abstract

Extraction equipment for needle - or ball-bearing (2) which can only be withdrawn in one direction from the machine housing (1) has two segment-like jaws (4, 5) which are similar in cross-section and have a flange segment (7, 8) on their lower ends. The jaws together with a central rod (10) form a jack block by means of which the bearing is extracted from the housing. Flange segments (11, 12) are provided on the upper ends of the jaws and are thrust into the slit (13) of the jack head (14) where they are held while the jack head and the connected bearing are knocked out. The central rod and the adjacent side surfaces of the jaws are wedge-shaped.

Description

" Lager-Ausziehgerät " Es bereitet immer große Schwierigkeiten, z.B. -ein Kugellager, Nadellager, Rollenlager oder irgendeine Buchse aus einem Maschinenblock herauszuziehen, wenn man von der inneren Seite des 5 Maschinenblocks an dieses Lager nicht heran kann es also mit einem geeigneten Bolzen nicht herausschlagen kann. Zudem sitzen die äußeren Lagerringe eines solchen Lagers im allgemeinen in der entsprechenden Bohrung sehr fest, da sie sich ja im Betrieb nicht darin verdrehen dürfen, Man hat hierfür zwar bereits sogenannte Kugellager-Auszieher entwickelt, diese befriedigen jedoch nicht in ihrer handhabung, da sie nur ungenügend die rückwärtige Seitenfläche des Lagers erfassen und daher leicht abrutschen0 Diese und weitere nachteile zu vermeiden ist Aufgabe vorliegender Erfindung, deren Lösung dadurch gekennzeichnet ist, daß dieses Lager Ausziehgerät besteht aus zwei gleichen im Querschnitt segmentartigen Backen, die an ihren unteren Enden jeweils ein Flanschsegment aufweisen und mit dem Mittelstab zusammen einen Hebeblock bilden, mittels welchem das Lager aus dem Gehäuse herausgezogen wird, Wie die Neuerung im einzelnen ausgeführt sein kann, ergibt sich aus der nachfolgenden Besonreibung und aus den Zeichnungen, in denen ein Ausführungsbeispiel zum Teil schematisch dargestellt ist, und zwar zeigen Fig. 1 eine Seitenansicht auf den Erfindungsgegenstand zum Teil im Schnitt dargestellt, Fig. 2 einen Querschnitt gem. der Schnittlinie I - II von Fig. 1 Fig. 3 eine teilweise Darstellung des Hebekopfes auf die Breitseite gesehen. "Bearing Extractor" It always presents great difficulties, e.g. -a ball bearing, needle roller bearing, roller bearing or any bushing from a machine block to be pulled out when looking at this bearing from the inside of the 5 machine block it cannot reach it, so it cannot knock out with a suitable bolt. In addition, the outer bearing rings of such a bearing are generally seated in the corresponding hole very tight, as they do not twist in it during operation so-called ball bearing extractors have already been developed for this purpose, However, these are not satisfactory in their handling, since they are insufficiently the rear Grasp the side surface of the bearing and therefore easily slip0 These and others It is the object of the present invention to avoid disadvantages and thereby to solve it it is characterized that this bearing extractor consists of two identical cross-sections segment-like jaws which each have a flange segment at their lower ends and together with the central rod form a lifting block by means of which the bearing is pulled out of the housing, How the innovation will be carried out in detail can be derived from the description below and from the drawings in which an embodiment is shown partially schematically, namely show 1 shows a side view of the subject matter of the invention, partly shown in section, 2 shows a cross section along the section line I - II of FIG. 1, and FIG. 3 shows a partial Representation of the lifting head seen from the broadside.

In dem Maschinengehäuse 1 sitzt das Nadel-, Kugel- oder sonstige Lager 2, welches bedingt durch die baulichen Verhältnisse des Maschinengehäuses 1 nur in Pfeilricntung 3, d.ho nach oben herausgezogen werden kann. Zu diesem Zweck wird zunächst eine der losen segmentartigen und gleichen Backen 4 oder 5 in die innere Bohrung 6 des Lagers 2 eingeführt, und zwar so, daß diese Backe 4 oder 5 mit ihrem unteren herausrazen- dem Flanschsegment 7 oder 8 unter die untere (hintere) Seitenfläche 9 des äußeren Lagerringes greift. Sobald eine dieser Backen, z0B. die Backe 5-7 in die Bohrung 6 eingeführt ist, wird diese mit ihrer Außenflache (Segmentfläche) an der inneren Wand der Bohrung 6 anliegend so gehalten, daß noch.genügend platz bleibt, um auch die andere Backe 4-8 in die Bohrung 6 einführen zu können, wobei beide Backen so eingeführt werden, daß die Flanschsegmente 7 u. 8 an der inneren Seitenwand 9 des Lagers 2 anliegen und diese genügend umgreifen. Hierbei bleibt zwischen den inneren Flächen der beiden Backens,7 und 4,8 noch ein freier Raum, in dem der lose Mittelstab 1U eingeschoben wird, der die Backen 5,7 und 4,8 an die innere Bohrungswand 6 leicht andrückt, Hiermit ist ein iiebeblock aus drei Teilen geschaffen, die eine Baueinheit bilden, mittels welcher das Lager aus dem Gehäuse herausgezogen werden kann0 Je nach Größe des Lagers kann der Hebeblock für verschiedene Lagergrößen Veruendung~finden vor allem dann, wenn der Mittel- stab / und seine Anlegeflächen etwas keilförmig ausgebildet sind. In the machine housing 1 sits the needle, ball or other bearing 2, which, due to the structural conditions of the machine housing 1, can only be pulled out in arrow direction 3, i.e. upwards. For this purpose, one of the loose segment-like and identical jaws 4 or 5 is first inserted into the inner bore 6 of the bearing 2, in such a way that this jaw 4 or 5 razes out with its lower the flange segment 7 or 8 engages under the lower (rear) side surface 9 of the outer bearing ring. As soon as one of these jaws, e.g. the jaw 5-7 is inserted into the bore 6, this is held with its outer surface (segment surface) resting against the inner wall of the bore 6 so that there is still enough space to also the other jaw 4-8 in the bore 6 Both jaws are inserted so that the flange segments 7 and 8 rest against the inner side wall 9 of the bearing 2 and encompass them sufficiently. This leaves a free space between the inner surfaces of the two jaws 7 and 4.8, in which the loose central rod 1U is inserted, which presses the jaws 5, 7 and 4 8 lightly against the inner bore wall 6 The lifting block is made up of three parts that form a structural unit by means of which the bearing can be pulled out of the housing. Depending on the size of the bearing, the lifting block can be used for different bearing sizes, especially when the rod / and its contact surfaces are somewhat wedge-shaped.

Wie der erfindungsgemäße tebeblock und damit auch das Lager nach oben in Pfeilrichtung 3 herausgezogen wird, ist an sic gleichgültig und kann auf verschiedene ort erfolgen.Like the tebeblock according to the invention and thus also the bearing upwards is pulled out in the direction of arrow 3 is indifferent about sic and can refer to different place.

Vorzugsweise haben diese Backen 5,7 -und 4, an ihren oberen Enden Flanschsegmente @@ und 12, die in einet Schlitz 13 des Hebekopfes 14 greifen und sich darin halten An diesem nebekopf 14 ist eine Stange 15 fest ode abschraubbar angeordnet, auf der ein Schlaggewlcht 16 gleitet bis an den Endflasch 17. Mit Schlagen in Pfeilrichtung 3 wird das mager 2 aus dem Gehäuse 1 mittels dem erfindungsgemäßen hebeblock 5,7 - 4,8 und 10 leicht herausgeschlagen.These jaws preferably have 5, 7 and 4 at their upper ends Flange segments @@ and 12, which engage in a slot 13 of the lifting head 14 and hold in it On this secondary head 14, a rod 15 is fixed or unscrewed arranged, on which a Schlaggewlcht 16 slides up to the end bottle 17. With beating in the direction of arrow 3, the lean 2 is removed from the housing 1 by means of the inventive Lifting block 5.7 - 4.8 and 10 easily knocked out.

Sie Neuerung ist nicht auf die dargestellten Einzelheiten beschränkt, vielmehr auch abgeåndert ausführbar, sofern nur die Erfindungsmerkmale zum Ausdruck kommen,The innovation is not limited to the details shown, Rather, it can also be executed in modified form, provided that only the features of the invention are expressed come,
