A device for placing i.e., pressing in and pulling off, bearings or sleeves, in particular for axle bearings and/or wheel flange hubs of motor vehicles, includes a threaded spindle with an abutment shoulder and threaded nut, a cylindrical spacer tube with a loosely insertable front wall receiving a thrust step bearing. The device includes several axial pressure pieces which can be arranged exchangeably on the threaded spindle between the threaded nut and a workpiece. To achieve universal usability, the spacer tube is provided on one side with an end ring surface interrupted by at least one wall cutout and on the other side with a centering cone or a centering rabbet. The front wall is insertable into the spacer tube through a centering projection selectively from both end faces. In addition, the thrust step bearing is accommodated in a bearing insertion part which can be screwed into a central threaded bore of the front wall and can be replaced with the threaded spindle e.g. by a hydraulic pressing device.

Description

Die Erfindung betrifft eine Vorrichtung zum Einpressen und Abziehen von Lagern oder Hülsen, insbesondere von Achslagern (Wälzlager) und/oder Radflanschnaben von Kraftfahrzeugen, bestehend aus
- einer Gewindespindel, die eine Anschlagschulter aufweist und mit einer Gewindemutter zusammenwirkt,
- einem zylindrischen Abstandsrohr, dem eine lösbare Stirnwand zugeordnet ist, in welcher ein Axialstützlager für die Anschlag­schulter der Gewindespindel konzentrisch angeordnet ist und welches an wenigstens einer Stirnseite zur zentrierenden Ab­stützung an einem Werkstückteil (Lagergehäuse oder Radflansch­nabe) oder zur Aufnahme eines zwischen Werkstückteil und Abstandhalter einbringbaren, auwechselbaren Stützrings ausgebil­det ist, sowie aus
- mehreren einzeln auswechselbar auf der Gewindespindel zwischen Gewindemutter und Werkstück anzuordnenden, mit unterschied­lichen Zentrieransätzen versehenen Axialdruckstücken.The invention relates to a device for pressing in and pulling off bearings or sleeves, in particular axle bearings (roller bearings) and / or wheel flange hubs of motor vehicles, consisting of
a threaded spindle which has a stop shoulder and interacts with a threaded nut,
- A cylindrical spacer tube, which is assigned a detachable end wall, in which an axial support bearing for the stop shoulder of the threaded spindle is arranged concentrically and which on at least one end face for centering support on a workpiece part (bearing housing or wheel flange hub) or for receiving a between the workpiece part and Spacer insertable, replaceable support ring is formed, as well as
- Several individually interchangeable axial pressure pieces to be arranged on the threaded spindle between the threaded nut and the workpiece and provided with different centering approaches.

Bei einer bekannten Vorrichtung dieser Art (DE-PS 35 30 983) ist das Abstandsrohr an beiden stirnseitigen Enden jeweils mit einem Innengewinde versehen, in welches einerseits die mit einem Gewindeansatz versehene Stirnwand mit dem Axialstütz­lager und andererseits einer der auswechselbaren Stützringe einschraubbar sind. Die Stirnwand selbst weist auf der dem Gewindeansatz gegenüberliegenden Außenseite eine zur zentralen Durchsteckbohrung für die Gewindespindel konzentrische Ausdrehung auf, in welcher das Axialstützlager untergebracht und befestigt ist.
Die bei dieser bekannten Vorrichtung vorgesehenen, im wesent­lichen als zylindrische Ringscheiben unterschiedlichen Durch­messers ausgebildeten Druckstücke sind jeweils nur auf einer Seite mit einem Zentrieransatz und auf der gegenüberliegenden Seite mit einer zylindrischen Ausdrehung zur zentrierenden Aufnahme eines zylindrischen Führungsteiles der Gewindemutter versehen, was bedeutet, daß sie jeweils nur in einer bestimmten Lage auf die Gewindespindel aufgesetzt werden können. Bei dieser bekannten Vorrichtung hat das Abstandsrohr, weil es an beiden Rohrenden jeweils ringsum in sich geschlossene Stirnflächen aufweist, den Nachteil, daß es bei solchen Lagerge­häusen von Kraftfahrzeugachsen, die keine ringsum ebene Aufla­gefläche haben, sondern mit Erhöhungen versehen sind, nicht verwendet werden kann. Außerdem ist die obwohl lösbar mit dem Abstandsrohr verbundene bzw. verbindbare Stirnwand ebenfalls nur in einer Zugrichtung verwendbar.In a known device of this type (DE-PS 35 30 983), the spacer tube is provided at both ends with an internal thread, into which the threaded end wall with the axial support bearing and on the other hand one of the interchangeable support rings can be screwed. The end wall itself has, on the outside opposite the threaded shoulder, a recess which is concentric with the central push-through hole for the threaded spindle and in which the axial support bearing is accommodated and fastened.
The pressure pieces provided in this known device, essentially designed as cylindrical washers of different diameters, are each provided on one side only with a centering projection and on the opposite side with a cylindrical recess for centering reception of a cylindrical guide part of the threaded nut, which means that they each can only be placed on the threaded spindle in a certain position. In this known device, the spacer tube has because it is closed all around at both tube ends End faces has the disadvantage that it can not be used in such bearing housings of motor vehicle axles that do not have a flat bearing surface all around, but are provided with elevations. In addition, the end wall, although detachably connected or connectable to the spacer tube, can likewise only be used in one pulling direction.

Der Erfindung liegt deshalb die Aufgabe zugrunde, die gattungs­gemäße Vorrichtung durch Umgestaltung einzelner Teile univer­seller einsetzbar zu machen.The invention is therefore based on the object of making the generic device more universally applicable by redesigning individual parts.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Abstandsrohr an einer Stirnseite eine durch wenigstens einen Wandausschnitt unterbrochene Stirnringfläche aufweist und/oder auf der anderen Stirnseite mit einem Zentrierkonus und/oder einem Zentrierfalz versehen ist und daß die Stirnwand durch einen Zentrieransatz von beiden Stirnseiten her zentriert in das Abstandsrohr lose einsetzbar ist.This object is achieved in that the spacer tube has an end face interrupted by at least one wall cut-out on one end face and / or is provided on the other end face with a centering cone and / or a centering rebate and in that the end wall is centered from both end faces by a centering approach can be inserted loosely into the spacer tube.

Durch die Ausgestaltung der Erfindung nach Anspruch 2 ergibt sich der Vorteil, daß an Stelle des für die Lagerung der Gewinde­spindel vorgesehenen Stützlagers in die Stirnwand beispielswei­se eine hydraulische Preßvorrichtung eingeschraubt werden kann, um die Vorrichtung auch dort einsetzen zu können, wo höhere Preßkräfte oder Zugkräfte erforderlich sind, die mit der Gewindespindel nicht erzeugbar sind.The embodiment of the invention according to claim 2 has the advantage that instead of the support bearing provided for the mounting of the threaded spindle, for example, a hydraulic pressing device can be screwed into the end wall in order to be able to use the device where higher pressing forces or tensile forces are required are that can not be generated with the threaded spindle.

Der nach Anspruch 3 ausgebildete Lagereinsatzteil bringt zusätz­lich den Vorteil mit sich, daß er wahlweise von der einen oder anderen Seite her in die Stirnwand eingeschraubt und diese wahlweise in der einen oder anderen Zug- bzw. Druckrichtung als Stützelement verwendet werden kann.The bearing insert part designed according to claim 3 has the additional advantage that it can be screwed into the end wall from one side or the other and this can optionally be used in one or the other pulling or pushing direction as a support element.

Durch die Ausgestaltung des Lagereinsatzteiles gem. Anspruch 4 ist der zusätzliche Vorteil gegeben, daß dieser selbst als Zentrierelement für ein einzupressendes Achslager dienen kann.Due to the design of the bearing insert according to Claim 4 is the additional advantage that it can serve itself as a centering element for an axle bearing to be pressed.

Während die Ausgestaltung der Erfindung nach Anspruch 5 der leichten Handhabung des Lagereinsatzteiles beim Ein- und Aus­schrauben in bzw. aus der Stirnwand dient, ist durch die Ausge­staltung der Erfindung nach Anspruch 6 die Möglichkeit gegeben, das Distanzrohr in Verbindung mit dem Adapterrohr auch bei solchen Achslagergehäusen von Kraftfahrzeugen insbesondere zum Herausziehen der Achslager, zu verwenden, bei denen die maximale Weite der stirnseitigen Stützfläche einen kleineren Durchmesser aufweist als das Abstandsrohr.While the embodiment of the invention according to claim 5 is used for easy handling of the bearing insert when screwing in and out of the end wall, the embodiment of the invention according to claim 6 enables the spacer tube in connection with the adapter tube also in such axle bearing housings of motor vehicles, in particular for pulling out the axle bearings, in which the maximum width of the end support surface has a smaller diameter than the spacer tube.

Durch die Ausgestaltung nach Anspruch 7 wird nicht nur eine zusätzliche Zentrierung zwischen der einen Stirnfläche des Ab­standsrohres und einem daran anliegenden Stützteil erzielt, sondern es wird auch sichergestellt, daß die unterbrochene Stirnfläche keinen radial nach außen drückenden Druckkräften sondern im Gegenteil nach innen wirkenden Druckkräften ausge­setzt wird, die ihre Bruchsicherheit erhöhen.The embodiment according to claim 7 not only achieves additional centering between the one end face of the spacer tube and a supporting part resting thereon, but it also ensures that the interrupted end face does not have any radially outward pressing forces on the contrary, it is exposed to inward pressure forces that increase their resistance to breakage.

Durch die Ausgestaltung der Erfindung nach Anspruch 8 ist auch die Möglichkeit gegeben, die Stirnwand selbst als zentrie­rendes Stützelement ohne das Abstandsrohr zu verwenden.The embodiment of the invention according to claim 8 also gives the possibility of using the end wall itself as a centering support element without the spacer tube.

Durch die Ausgestaltung der Druckstücke nach Anspruch 9 sind diese auch beidseitig verwendbar, so daß sich ihre für die unterschiedlichen Anwendungsfälle erforderliche Anzahl auf etwa die Hälfte reduziert.Due to the design of the pressure pieces according to claim 9, these can also be used on both sides, so that their number required for the different applications is reduced to about half.

Durch das Vorsehen einer nach Anspruch 10 ausgebildeten Ge­windemutter vereinfacht sich die Handhabung der Vorrichtung in bestimmten Anwendungsfällen und zwar dort, wo ihre Flansch­scheibe unmittelbar von einer entsprechend ausgebildeten stirn­seitigen Randfläche eines Achslagergehäuses zentrierend aufge­setzt werden kann.The provision of a threaded nut designed according to claim 10 simplifies the handling of the device in certain applications, specifically where its flange disc can be placed centering directly from a correspondingly configured end face of an axle bearing housing.

The invention is explained in more detail below with the aid of the drawing. It shows:
  • Figure 1 shows a device and a wheel bearing of a motor vehicle in a perspective exploded view.
  • Figure 2 shows various components of the device in a coaxial arrangement and a sectional view.
  • Fig. 3 shows a number of different pressure pieces in cut Presentation;
  • 4 shows the device when a wheel bearing (roller bearing) is pressed out of the wheel bearing housing of a motor vehicle;
  • Fig. 5 shows the device when pressing a wheel bearing into the wheel bearing housing of a motor vehicle also shown in Fig. 4.

Die in der Zeichnung dargestellte Vorrichtung besteht aus einer Gewindespindel 1, einem Lagereinsatzteil 2, einer kreisscheibenarti­gen Stirnwand 3, einem Abstandsrohr 4, aus Stützringen 5 und 6, einem Adapterrohr 7, aus mehreren Axialdruckstücken 8, 9, 10 und 11, sowie aus einer Gewindemutter 12 und einer diese ersetzenden Flanschscheibe 13.
Die Gewindespindel 1 ist am einen Ende mit einem Ringflansch 14 und dahinter mit einem Schlüsselprofil 15 versehen, das vorzugsweise eine Sechskantform aufweist. Außerdem besitzt die Gewindespindel einen zylindrischen Zentrieransatz 16, der an einer ringförmigen Anschlagschulter 17 des Ringflansches 14 endet.
Der Lagereinsatzteil 2 weist einen Gewindeansatz 18 auf, dessen axiale Länge etwa der Gesamtdicke der Stirnwand 3 entspricht und der in eine zentrale Gewindebohrung 19 der Stirnwand 3 wechselweise von beiden Seiten her einschraubbar ist. An den Gewindeansatz 18 schließt sich ein im Durchmesser größerer, zylindrischer Zentrierkopf 20 an, der auf der dem Gewindeansatz zugekehrten Seite eine radiale Anschlagschulter 21 aufweist und auf seiner Mantelfläche mit einem Kreuzrändel 22 versehen ist. Statt des Kreuzrändels 22 oder zusätzlich dazu, kann der Zentrierkopf mit zwei parallelen Schlüsselflächen versehen sein, damit er im Falle eines Festsitzens in der Gewindebohrung 19 mittels eines Schlüssels herausgedreht werden kann.
Wie am besten aus Fig. 2 ersichtlich ist, ist der Lagereinsatz­teil mit einer Durchsteckbohrung 23 für die Gewindespindel 1 versehen. Beidseits eines sich etwa in der axialen Mitte be­findenden Ringsteges 24 weist er außerdem in zwei zylindrischen Ausnehmungen 25 jeweils ein mittels eines axialen Sicherungsringes 26 bzw. 27 gesichertes Axialstützlager 28 bzw. 29 auf, die dem Ringflansch 14 der Gewindespindel 1 wechselweise als Anlage dienen können.
Der Gewindeansatz 18 und die Gewindebohrung 19 sind so ge­staltet, daß statt des Lagereinsatzteils 2 in die Gewindebohrung 19 auch ein hydraulisches Druckaggregat eingesetzt werden kann, mit dem größere Axialkräfte erzeugt werden können, als dies mit der Gewindespindel 1 möglich ist.The device shown in the drawing consists of a threaded spindle 1, a bearing insert 2, a circular disk-like end wall 3, a spacer tube 4, support rings 5 and 6, an adapter tube 7, several axial pressure pieces 8, 9, 10 and 11, and a threaded nut 12 and a flange disk 13 replacing them.
The threaded spindle 1 is provided at one end with an annular flange 14 and behind it with a key profile 15, which preferably has a hexagonal shape. In addition, the threaded spindle has a cylindrical centering projection 16, which ends at an annular stop shoulder 17 of the ring flange 14.
The bearing insert part 2 has a threaded shoulder 18, the axial length of which corresponds approximately to the total thickness of the end wall 3 and which can be screwed into a central threaded bore 19 of the end wall 3 alternately from both sides. A threaded centering head 20 adjoins the threaded extension 18, which is larger than the threaded extension facing side has a radial stop shoulder 21 and is provided on its outer surface with a cross knurl 22. Instead of the cross knurl 22 or in addition thereto, the centering head can be provided with two parallel key surfaces so that it can be unscrewed in the threaded bore 19 by means of a key in the event of a tight fit.
As can best be seen from FIG. 2, the bearing insert part is provided with a through hole 23 for the threaded spindle 1. On both sides of an annular web 24 located approximately in the axial center, it also has, in two cylindrical recesses 25, an axial support bearing 28 or 29 secured by means of an axial locking ring 26 or 27, which can alternately serve as an attachment to the annular flange 14 of the threaded spindle 1.
The threaded shoulder 18 and the threaded bore 19 are designed such that, instead of the bearing insert part 2, a hydraulic pressure unit can also be used in the threaded bore 19, with which greater axial forces can be generated than is possible with the threaded spindle 1.

Die Stirnwand 3 besitzt einen auf den Innendurchmesser des Abstandsrohres 4 abgestimmten zylindrischen Zentrieransatz 30, an welchen sich ein in seinem Außendurchmesser auf den Außendurchmesser des Abstandsrohres 4 abgestimmter Ringflansch 31 anschließt, dessen dem Zentrieransatz zugekehrte Ringfläche 32 um einen Hinterschnittwinkel α von ca. 5° hinterschnitten ist. Während die Stirnfläche 33 des Zentrieransatzes 30 planeben ist, weist die gegenüberliegende Stirnfläche 34 der Stirnwand 3 zwei stufenförmig angedrehte kurze Zentrieransätze 35 und 36 auf, an denen beispielsweise einzupressende Wälzlagerschalen zentriert werden können.The end wall 3 has a cylindrical centering projection 30 matched to the inner diameter of the spacer tube 4, to which is connected an annular flange 31 matched in its outer diameter to the outer diameter of the spacer tube 4, the annular surface 32 of which facing the centering boss undercut by an undercut angle α of approximately 5 ° is. While the end face 33 of the centering lug 30 is flat, the opposite end face 34 of the end wall 3 has two short centering lugs 35 and 36 which are turned on in steps, on which, for example, roller bearing shells to be pressed in can be centered.

Das Abstandsrohr, das in der praktischen Ausführung einen Außendurchmesser von etwa 99,5 mm und eine Wanddicke von etwa 7,5 mm aufweist, ist innen und außen vollständig zylindrisch und mit einer axialen Länge von etwa 80 mm versehen. An seiner einen Stirnseite ist seine zur Abstützung an Stirnflächen von Radlagergehäusen von Kraftfahrzeugen dienende Stirnringfläche 37 durch drei in axialer Richtung verschieden tiefe Wandaus­schnitte 38, 39 und 40 unterbrochen, so daß nur zwei sich etwa diametral gegenüberliegende Ringsektoren vorhanden sind. Diese Ausschnitte 38, 39, 40 dienen zur ungehinderten Aufnahme von Vorsprüngen und Erhebungen, welche bei manchen Fahrzeugtypen an den Radlagergehäusen, an denen das Abstandsrohr 4 zum Herausziehen des Radlagers angesetzt werden muß, vorhanden sind.
Durch diese Wandausschnitte 38, 39 und 40 entsteht eine Schwä­chung des Abstandsrohres. Um diese Schwächung auszugleichen, ist die Stirnfläche 37 analog zur Ringfläche 32 der Stirnwand 3 mit einem Konuswinkel α von ebenfalls 5° angeschrägt, so daß beim Aufsetzen der Stirnwand 3 auf die Stirnringflächen­abschnitte 37 in der in Fig. 4 dargestellten Weise die die Stirn­ wandabschnitte 37 aufweisenden Wandabschnitte des Abstandsrohres 4 bei axialer Belastung nicht radial nach außen, sondern eher nach innen gegen den Zentrieransatz 30 gepreßt werden.The spacer tube, which in the practical version has an outside diameter of about 99.5 mm and a wall thickness of about 7.5 mm, is completely cylindrical on the inside and outside and has an axial length of about 80 mm. On its one end face, its end ring surface 37, which is used to support end faces of wheel bearing housings of motor vehicles, is interrupted by three wall cutouts 38, 39 and 40 of different depths in the axial direction, so that only two ring sectors which are approximately diametrically opposed are present. These cutouts 38, 39, 40 serve for the unimpeded reception of projections and elevations which are present in some types of vehicles on the wheel bearing housings on which the spacer tube 4 has to be attached for pulling out the wheel bearing.
These wall cutouts 38, 39 and 40 weaken the spacer tube. In order to compensate for this weakening, the end face 37 is beveled analogously to the annular surface 32 of the end wall 3 with a cone angle α of also 5 °, so that when the end wall 3 is placed on the end face surface sections 37 in the manner shown in FIG. 4, the forehead Wall sections 37 having wall sections of the spacer tube 4 are not pressed radially outwards under axial loading, but rather inwards against the centering projection 30.

Auf der den Wandausschnitten 38, 39 und 40 gegenüberliegenden Stirnseite ist das Abstandsrohr 4 mit einem zentrierenden Innen­konus 41 und daran anschließend mit einem Zentrierfalz 42 versehen, die beide auf entsprechend ausgebildete Stirnflächen unterschiedlicher Achslagergehäuse von Kraftfahrzeugen abgestimmt sind.On the end face opposite the wall cutouts 38, 39 and 40, the spacer tube 4 is provided with a centering inner cone 41 and then with a centering fold 42, both of which are matched to appropriately designed end faces of different axle bearing housings of motor vehicles.

Auch die mit jeweils mehreren äußeren und inneren ringförmi­gen Stützschultern unterschiedlicher Durchmesser versehenen Stützringe 5 und 6 sowie das Adapterrohr 7 weisen jeweils wie die Stirnwand 3 als Stützschultern dienende Ringflächen 43, 44 bzw. 45 auf, die jeweils mit einem Hinterschnittwinkel von ebenfalls 5° hinterschnitten sind. Der Zweck dieses Hinterschnitts ist der gleiche wie bei der Ringfläche 32.The support rings 5 and 6, each provided with a plurality of outer and inner ring-shaped support shoulders of different diameters, and the adapter tube 7, like the end wall 3, also have ring surfaces 43, 44 and 45 serving as support shoulders, each of which is undercut with an undercut angle of likewise 5 ° . The purpose of this undercut is the same as for the ring surface 32.

Im übrigen dienen die beiden Stützringe 5 und 6 dem gleichen Zweck wie bei der bekannten Vorrichtung lediglich mit dem Unterschied, daß sie keine Gewindeansätze aufweisen, sondern jeweils lose stirnseitig auf das Distanzrohr 4 aufsetzbar sind.Otherwise, the two support rings 5 and 6 serve the same purpose as in the known device, only with the difference that they have no threaded attachments, but rather can be placed loosely on the end of the spacer tube 4.

Das Adapterrohr 7 ist am einen Ende mit einem zylindrischen Zentrieransatz 46 versehen, dessen Außendurchmesser auf den Innendurchmesser des Abstandsrohres 4 abgestimmt ist, so daß er von diesem mit geringem radialem Spiel leicht aufgenommen werden kann. Der auf der gegenüberliegenden Seite der Ring­fläche 45 liegende Verlängerungsteil 46′ hat eine sich zur gegen­überliegenden Stirnfläche 47 hin verjüngende konische Form, so daß sein Stirnflächenaußendurchmesser D kleiner ist als der Außendurchmesser des Distanzrohres 4. Dieses Adapterrohr wird als Verlängerung des Abstandsrohres 4 überall dort ver­wendet, wo ein Achslagergehäuse eine stirnseitige Ringstützflä­che aufweist, deren größter Außendurchmesser kleiner ist als der Außendurchmesser des Abstandsrohres 4 und deswegen das Abstandsrohr 4 selbst dort nicht zentrierend angesetzt werden kann.The adapter tube 7 is provided at one end with a cylindrical centering projection 46, the outer diameter of which Inner diameter of the spacer tube 4 is matched so that it can be easily accommodated by this with little radial play. The lying on the opposite side of the annular surface 45 extension 46 'has a conical shape tapering towards the opposite end surface 47, so that its outer surface outer diameter D is smaller than the outer diameter of the spacer tube 4. This adapter tube is used as an extension of the spacer tube 4 everywhere there, where an axle bearing housing has an end-face ring support surface, the largest outer diameter of which is smaller than the outer diameter of the spacer tube 4 and therefore the spacer tube 4 itself cannot be centered there.

Die im wesentlichen als zylindrische Ringscheiben unterschied­lichen Durchmesser ausgebildeten und jeweils mit einem oder zwei zylindrischen Zentrieransätzen 49 bis 55 unterschiedlichen Durchmessers versehenen Druckstücke 8, 9, 10 und 11, die wahlweise auf die Gewindespindel 1 aufgesetzt werden können, sind in ihrer Form auf unterschiedliche Wälzlager 56 abgestimmt, damit sie von diesen in der in Fig. 1 und 4 dargestellten Weise zentrie­rend aufgenommen werden können.The pressure pieces 8, 9, 10 and 11, which are designed essentially as cylindrical annular disks of different diameters and each have one or two cylindrical centering shoulders 49 to 55 of different diameters, and which can optionally be placed on the threaded spindle 1, are in their form on different rolling bearings 56 matched so that they can be centered in the manner shown in FIGS. 1 and 4.

Es ist in Fig. 1 erkennbar, daß die Gewindemutter 12 mit einem als Sechskant ausgebildeten Schlüsselprofil 59 und aus einem sich unmittelbar daran anschließenden, zylindrischen Zentrier­ teil 60 besteht. Zur zentrierenden Aufnahme dieses Zentriertei­les 60 der Gewindemutter 12 sind alle Druckstücke 8, 9, 10 und 11 jeweils beidseitig mit falzartigen, zylindrischen Aus­drehungen 61 versehen.It can be seen in Fig. 1 that the threaded nut 12 with a key profile 59 designed as a hexagon and from a directly adjoining cylindrical centering part 60 exists. For centering reception of this centering part 60 of the threaded nut 12, all pressure pieces 8, 9, 10 and 11 are provided on both sides with fold-like, cylindrical recesses 61.

In Fig. 1 ist die Vorrichtung so dargestellt, wie sie zum Ein­pressen eines Wälzlagers 56 in das Lagergehäuse 57 eines Kraft­fahrzeuges-Achsschenkels 58 unter Verwendung sowohl des Abstands­rohres 4 als auch eines Stützringes 5 und des Druckstückes 8 benutzt wird. Man stelle sich dabei vor, daß der Lagereinsatz­teil 2 vollständig in die Gewindebohrung 19 der Stirnwand 3 eingeschraubt ist, daß die Gewindespindel 1 durch den Lager­einsatzteil 2 hindurchgesteckt ist und das Abstandsrohr 4, den Stützring 5, das Lagergehäuse 57, das Wälzlager 56, und das Druckstück 8 durchragt und daß die Gewindemutter 12 auf das aus dem Druckstück 8 herausragende Ender der Gewindespindel 1 aufgeschraubt ist. Die Stirnwand 3 ist dabei ebenso im Ab­standsrohr 4 zentriert wie der mit einer seiner inneren Stütz­schultern an der Stirnseite 57′ des Lagergehäuese 57 zentrierte Stützring 5. Durch die gleichzeitige Zentrierung des Druckstückes 8 im Wälzlager 56 ist sichergestellt, daß die beim Anziehen der Gewindespindel 1 unter gleichzeitigem Festhalten der Gewin­demutter 12 auf das Lagergehäuse 57 und das Wälzlager 56 ausgeübten Axialkräfte eine Verkantung des Wälzlagers nicht zulassen, sondern eine einwandfreie Einführung des Wälzlagers in das Lagergehäuse 57 garantieren.In Fig. 1, the device is shown as it is used for pressing a rolling bearing 56 into the bearing housing 57 of a motor vehicle steering knuckle 58 using both the spacer tube 4 and a support ring 5 and the pressure piece 8. Imagine that the bearing insert 2 is completely screwed into the threaded bore 19 of the end wall 3, that the threaded spindle 1 is inserted through the bearing insert 2 and the spacer tube 4, the support ring 5, the bearing housing 57, the roller bearing 56, and that Thrust piece 8 protrudes and that the threaded nut 12 is screwed onto the end of the threaded spindle 1 protruding from the pressure piece 8. The end wall 3 is also centered in the spacer tube 4 as with one of its inner support shoulders on the end face 57 'of the bearing housing 57 centered support ring 5. The simultaneous centering of the pressure piece 8 in the roller bearing 56 ensures that when tightening the threaded spindle 1 under simultaneous retention of the threaded nut 12 on the bearing housing 57 and the roller bearing 56 do not allow tilting of the roller bearing, but rather guarantee a faultless insertion of the roller bearing into the bearing housing 57.

Beim Anwendungsbeispiel der Fig. 5 werden von der erfindungs­gemäßen Vorrichtung zum Einpressen eines Wälzlagers 56 in ein anderes Lagergehäuse 62 nur die Gewindespindel 1, die Stirnwand 3 mit dem eingesetzten Lagereinsatzteil 2 und statt der Gewindemutter 12 die Flanschscheibe 13 verwendet. Diese Flanschscheibe 13 besitzt eine zentrale, auf die Gewindespindel 1 passende Gewindebohrung 63 und einen zylindrischen Naben­ansatz 64. Auf der dem Nabenansatz 64 gegenüberliegenden Stirnfläche ist die Flanschscheibe in Umfangsnähe mit einer im Querschnitt etwa halbkreisförmigen Ringnut 65 versehen, die von einer ebenfalls halbkreisförmigen Ringrippe 66 umgeben ist. Das Querschnittsprofil der Ringnut 65 und der Ringrippe 66 sind wie in Fig. 5 dargestellt ist, an ein entsprechendes Gegenprofil 67 auf der Stirnseite 68 des Lagergehäuses 62 angepaßt, so daß die Flanschscheibe 13 dort zentrierend in der dargestell­ten Weise angesetzt werden kann, um das Wälzlager 56 in Richtung des Pfeiles 69 in das Lagergehäuse 62 einzupressen.In the application example of FIG. 5, only the threaded spindle 1, the end wall 3 with the inserted bearing insert 2 and, instead of the threaded nut 12, the flange disk 13 are used by the device according to the invention for pressing a rolling bearing 56 into another bearing housing 62. This flange disk 13 has a central threaded bore 63 which fits onto the threaded spindle 1 and a cylindrical hub shoulder 64. On the end face opposite the hub hub 64, the flange disk is provided in the vicinity of the circumference with an approximately semicircular annular groove 65, which is also surrounded by a semicircular annular rib 66 is. The cross-sectional profile of the annular groove 65 and the annular rib 66 are, as shown in Fig. 5, adapted to a corresponding counter profile 67 on the end face 68 of the bearing housing 62, so that the flange disc 13 can be centered there in the manner shown to the rolling bearing 56 in the direction of arrow 69 in the bearing housing 62.

Um jedoch das gleiche Wälzlager 56 aus dem Gehäuse 62 heraus­ziehen zu können, werden von der Vorrichtung -wie Fig. 4 zeigt- außer der Gewindespindel 1 die Stirnwand 3, das Abstands­rohr 4 und das Druckstück 11 sowie die Gewindemutter 12 be­nötigt. Das Abstandsrohr 4 wird dabei auf die ringförmige Stirnfläche 70 des Lagergehäuses 62 aufgesetzt. Diese Stirnfläche 70 ist mit einer konischen Facette 71 versehen, welche exakt in den Innenkonus 41 des Abstandsrohres 4 paßt, so daß sich dieses an dieser Facette 71 zentriert. Es ist auch erkennbar, daß der Zentrieransatz 51 des Druckstückes 11 in die Bohrung des Wälzlagers 56 zentrierend hineinragt, so daß beim Drehen der Gewindespindel 1 in Zugrichtung die auf das Wälzlager 56 und das Lagergehäuse 62 wirkenden Kräfte exakt axial verlau­fen und kein Verkanten zulassen.However, in order to be able to pull the same roller bearing 56 out of the housing 62, the device — as shown in FIG. 4 — requires the end wall 3, the spacer tube 4 and the pressure piece 11 as well as the threaded nut 12 in addition to the threaded spindle 1. The spacer tube 4 is placed on the annular end face 70 of the bearing housing 62. This end face 70 is provided with a conical facet 71 which is exact fits into the inner cone 41 of the spacer tube 4 so that it is centered on this facet 71. It can also be seen that the centering projection 51 of the pressure piece 11 protrudes centering into the bore of the roller bearing 56, so that when the threaded spindle 1 is rotated in the pulling direction, the forces acting on the roller bearing 56 and the bearing housing 62 run exactly axially and do not permit tilting.

Durch die drei in den Fig. 1, 4 und 5 dargestellten Anwendungs­beispiele ist gezeigt, daß je nach Anwendungsfall unterschied­liche Teile der Gesamtvorrichtung zur Anwendung kommen. Durch die erfindungsgemäße Gestaltung der einzelnen Bestandtei­le der Vorrichtung ist jedoch erreicht, daß diese in minimaler Anzahl für nahezu alle Anwendungsfälle beim Einpressen und Abziehen von Achslagern ausreichen.The three application examples shown in FIGS. 1, 4 and 5 show that, depending on the application, different parts of the overall device are used. The inventive design of the individual components of the device, however, ensures that these are sufficient in minimal number for almost all applications when pressing in and pulling off axle bearings.
