Definitions
- the invention relates to a pulling device for pulling a rolling bearing from a shaft, according to the preamble of claim 1, as is known from DE-A-819830.
- the cone of the clamping sleeve slides on the conical outer surface, which is formed by the spring tongues, in accordance with the rotation and displacement movement of the clamping sleeve.
- strong frictional forces act on the conical contact surfaces, so that for the rotational movement of the clamping sleeve requires large forces that can only be applied using auxiliary tools such as hook or fork wrenches.
- the wear on the conical contact surfaces is high.
- the clamping sleeve is divided into a pressure sleeve and an adjusting sleeve, but these two sleeves lie directly against one another with their facing end faces, so that considerable frictional forces have to be overcome in order to twist the adjusting sleeve .
- the pressure sleeve can also be rotated unintentionally. In addition, it is not possible to reset the pressure sleeve by means of the adjusting sleeve.
- the invention has for its object to simplify the handling of the puller.
- the object is achieved according to the invention with the characterizing features of claim 1.
- the inventive two-part design of the adapter sleeve with the connection via driver and bearing makes it possible to transmit only the axial forces to the spring tongues of the withdrawal sleeve, since only the adjusting sleeve forming part of the adapter sleeve is rotated on the hollow body and thereby relative to the other Part of the clamping sleeve forming the pressure sleeve rotates, but axially entrains this pressure sleeve. In this case, only a sliding movement in the axial direction arises between the conical contact surfaces, and the friction is considerably reduced in comparison to the known pulling devices, so that considerably lower actuating forces are accordingly required.
- the device has a hollow body 1 through which a threaded spindle 2 passes.
- the hollow body consists of a withdrawal sleeve 3, a shaft 4 screwed into this sleeve and a threaded insert 5 screwed into the shaft, which has an internal thread 6 for the spindle 2 provided with an external thread 7.
- the division of the hollow body 1 into the withdrawal sleeve 3 and the shaft 4 makes it possible to use withdrawal sleeves of different types while maintaining the remaining parts of the device, as is described in detail in the aforementioned DE-AS 1 269 069.
- the puller can also be extended if necessary by inserting a further shaft corresponding to the shaft 4, since the threaded insert 5 can also be unscrewed and a correspondingly longer threaded spindle 2 is to be used.
- the withdrawal sleeve 3 is axially slotted up to close to its threaded end, so that separate tongues 9 are formed by slots 8, which are designed to be radial to the longitudinal axis A of the withdrawal device.
- These spring tongues have outwardly flared ends 10 which form a conical outer surface 11 of the withdrawal sleeve 3.
- the free ends of the conical ends 10 form pull-off elements 12, which in the exemplary embodiment are designed as grippers, but can also be claws, as are shown in DE-AS 1 269 069.
- the pulling grippers 12 grip over the rollers of a tapered roller bearing to be removed and thereby grasp this bearing, for which purpose the spindle 2 is supported with its inner end on the end face of the shaft on which the bearing is seated.
- an adapter sleeve 13 is provided, which essentially consists of a pressure sleeve 14 and an adjusting sleeve 15.
- the pressure sleeve 14 ends in an inner cone 16, which has the same apex angle as the conical lateral surface 11 and accordingly rests with its inner lateral surface 17 on the surface 11 without play.
- the pressure sleeve 14 is axially displaced by means of the adjusting sleeve 15.
- the adjusting sleeve 15 with its internal thread 18 can be rotated on an external thread 19 of the shaft 4 and is thereby axially adjustable.
- a driver designed as an annular disk 20 is provided, which is arranged with a press fit in the adjusting sleeve 15 and bears against a shoulder 21 of this sleeve, that is to say can be rotated with the adjusting sleeve.
- One of two axial needle bearings 22 and 23 is located on either side of the annular disk 20.
- the outer ring 24 of the bearing 22 is supported on a shoulder 25 of the pressure sleeve 14.
- the outer ring 26 of the bearing 23 lies against a snap ring 27 which is inserted into the pressure sleeve 14 and which forms a fixed driver and does not touch the adjusting sleeve.
- Another driver also designed as a snap ring 28, is inserted into the adjusting sleeve 15 near one end thereof.
- a pot ring 29 which serves as a dust seal for the double bearing 22, 23 and with the outer ring 24 of the bearing 22 and with the outer surface of the pressure sleeve 14 forms a gap of very small width, so that it with them Sharing is not in touch.
- a guide pin 30 is inserted into the pressure sleeve 14, which is slidably guided in an axial guide slot 31 of the shaft 4.
- an annular gap of small width is an annular gap of small width, so that there is no surface contact.
- the axial thrust force is transmitted via the driver 28, the pot ring 29, the driver 20, the bearing ring 26 and the driver 27 to the pressure sleeve 14, which is axially guided in the same way.
- the adjusting sleeve 15 can be rotated by hand, which is facilitated by an external corrugation 32A.
- two recesses 32 and 33 are provided in the adjusting sleeve 15, into which an adjusting tool, for example an open-ended wrench, can engage.
- Two openings 34 and 35 are also provided in the threaded insert 5 for the use of such an auxiliary tool.
- the withdrawal sleeve 14 also has two recesses 36 and 37 in order to support the withdrawal movement by means of an auxiliary tool if necessary.
Description
Die Erfindung betrifft eine Abziehvorrichtung zum Abziehen eines Wälzlagers von einer Welle, nach dem Oberbegriff des Patentanspruches 1, wie sie aus der DE-A-819830 bekannt ist.The invention relates to a pulling device for pulling a rolling bearing from a shaft, according to the preamble of claim 1, as is known from DE-A-819830.
Es ist eine Abziehvorrichtung dieser Art, jedoch mit einteiliger Spannhülse bekannt (DE-A-1269069). Sie kann mittels der Gewindespindel auf das abzuziehende Wälzlager derart aufgesetzt werden, daß die Federzungen mit ihren als Greifer ausgebildeten Abziehelementen die Wälzkörper, beispielsweise die Rollen eines Kegelrollenlagers ergreifen, wonach die Spannhülse durch Drehen auf dem Hohlkörper axial verschoben wird und dadurch über die konischen Anlageflächen die Federzungen radial verstellt, so daß die Abziehgreifer die Rollen umgreifen oder auch den Innenring oder den Außenring des Wälzlagers hintergreifen. Durch axiale Zugbewegung kann dann das Wälzlager mittels der Vorrichtung von der Welle abgezogen werden. Bei der radialen Stellbewegung der Federzungen gleitet der Konus der Spannhülse auf der konischen Mantelfläche, die von den Federzungen gebildet ist, entsprechend der Dreh- und Verschiebebewegung der Spannhülse. Dadurch wirken an den konischen Anlageflächen starke Reibungskräfte, so daß für die Drehbewegung der Spannhülse große Kräfte erforderlich sind, die nur mittels Hilfswerkzeugen wie Haken- oder Gabelschlüsseln aufgebracht werden können. Außerdem ist der Verschleiß an den konischen Anlageflächen hoch.It is a puller of this type, but known with a one-piece adapter sleeve (DE-A-1269069). It can be placed on the roller bearing to be removed by means of the threaded spindle in such a way that the spring tongues with their pulling elements designed as grippers grip the rolling elements, for example the rollers of a tapered roller bearing, after which the clamping sleeve is axially displaced by turning on the hollow body and thereby over the conical contact surfaces Spring tongues are adjusted radially so that the pulling grippers engage around the rollers or also engage behind the inner ring or the outer ring of the rolling bearing. The rolling bearing can then be pulled off the shaft by means of the device by means of an axial pulling movement. During the radial adjusting movement of the spring tongues, the cone of the clamping sleeve slides on the conical outer surface, which is formed by the spring tongues, in accordance with the rotation and displacement movement of the clamping sleeve. As a result, strong frictional forces act on the conical contact surfaces, so that for the rotational movement of the clamping sleeve requires large forces that can only be applied using auxiliary tools such as hook or fork wrenches. In addition, the wear on the conical contact surfaces is high.
Bei der gattungsgemäßen Spannvorrichtung (DE-A-819830) ist die Spannhülse zwar in eine Druckhülse und eine Stellhülse unterteilt, jedoch liegen diese beiden Hülsen mit ihren einander zugekehrten Stirnflächen unmittelbar aneinander an, so daß beträchtliche Reibkräfte überwunden werden müssen, um die Stellhülse zu verdrehen. Dabei kann die Druckhülse ungewollt mitgedreht werden. Außerdem ist eine Rückstellung der Druckhülse mittels der Stellhülse nicht möglich.In the generic clamping device (DE-A-819830), the clamping sleeve is divided into a pressure sleeve and an adjusting sleeve, but these two sleeves lie directly against one another with their facing end faces, so that considerable frictional forces have to be overcome in order to twist the adjusting sleeve . The pressure sleeve can also be rotated unintentionally. In addition, it is not possible to reset the pressure sleeve by means of the adjusting sleeve.
Der Erfindung liegt die Aufgabe zugrunde, die Handhabung der Abziehvorrichtung zu vereinfachen.The invention has for its object to simplify the handling of the puller.
Die Aufgabe wird gemäß der Erfindung mit den kennzeichnenden Merkmalen des Patentanspruches 1 gelöst. Die erfindungsgemäße zweiteilige Ausfuhrung der Spannhülse mit der Verbindung über Mitnehmer und Lager ermöglicht es, auf die Federzungen der Abziehhülse nur die Axialkräfte zu übertragen, da nur die den einen Teil der Spannhülse bildende Stellhülse auf dem Hohlkörper verdreht wird und sich dabei relativ zu der den anderen Teil der Spannhülse bildenden Druckhülse dreht, diese Druckhülse aber axial mitnimmt. Dabei entsteht zwischen den konischen Anlageflächen lediglich eine Verschiebebewegung in axialer Richtung, und die Reibung wird im Vergleich zu den bekannten Abziehvorrichtungen beachtlich vermindert, so daß dementsprechend wesentlich geringere Stellkräfte erforderlich sind. Außerdem wird auch der Verschleiß an den konischen Anlageflächen erheblich vermindert. Das Öffnen und Schließen der Abziehhülse, also die radiale Verstellung der Federzungen, ist ohne Hilfswerkzeuge möglich, da die Druckhülse und die Stellhülse über Mitnehmer verbunden sind, die gegeneinander durch Lager abgestützt sind.The object is achieved according to the invention with the characterizing features of claim 1. The inventive two-part design of the adapter sleeve with the connection via driver and bearing makes it possible to transmit only the axial forces to the spring tongues of the withdrawal sleeve, since only the adjusting sleeve forming part of the adapter sleeve is rotated on the hollow body and thereby relative to the other Part of the clamping sleeve forming the pressure sleeve rotates, but axially entrains this pressure sleeve. In this case, only a sliding movement in the axial direction arises between the conical contact surfaces, and the friction is considerably reduced in comparison to the known pulling devices, so that considerably lower actuating forces are accordingly required. In addition, the wear on the conical contact surfaces is significantly reduced. The opening and closing of the withdrawal sleeve, ie the radial adjustment of the spring tongues, is possible without auxiliary tools, since the pressure sleeve and the adjusting sleeve are connected via drivers which are supported against one another by bearings.
Weitere Merkmale der Erfindung ergeben sich aus den übrigen Ansprüchen und der folgenden Beschreibung in Verbindung mit der Zeichnung, die ein Ausführungsbeispiel der erfindungsgemäßen Abziehvorrichtung in Seitenansicht und teilweise im Axialschnitt zeigt.Further features of the invention emerge from the remaining claims and the following description in conjunction with the drawing, which shows an embodiment of the pulling device according to the invention in side view and partially in axial section.
Die Vorrichtung hat einen Hohlkörper 1, der von einer Gewindespindel 2 durchsetzt ist. Der Hohlkörper besteht aus einer Abziehhülse 3, einem in diese Hülse eingeschraubten Schaft 4 und einem in den Schaft eingeschraubten Gewindeeinsatz 5, der ein Innengewinde 6 für die mit Außengewinde 7 versehene Spindel 2 aufweist. Die Aufteilung des Hohlkörpers 1 in die Abziehhülse 3 und den Schaft 4 ermöglicht es, unter Beibehaltung der übrigen Teile der Vorrichtung Abziehhülsen unterschiedlicher Art zu verwenden, wie dies in der eingangs genannten DE-AS 1 269 069 im einzelnen beschrieben ist. Auch kann die Abziehvorrichtung bei Bedarf durch Einsetzen eines weiteren Schaftes entsprechend dem Schaft 4 verlängert werden, da auch der Gewindeeinsatz 5 abgeschraubt werden kann und eine entsprechend längere Gewindespindel 2 zu verwenden ist.The device has a hollow body 1 through which a threaded
Die Abziehhülse 3 ist bis nahe an ihr mit Gewinde versehenes Ende axial geschlitzt, so daß durch Schlitze 8 getrennte Zungen 9 gebildet sind, die radial zur Längsachse A der Abziehvorrichtung federnd ausgebildet sind. Diese Federzungen haben nach außen konisch erweiterte Enden 10, die eine konische Mantelfläche 11 der Abziehhülse 3 bilden. Die konischen Enden 10 bilden mit ihren freien Enden Abziehelemente 12, die im Ausführungsbeispiel als Greifer gestaltet sind, aber auch Klauen sein können, wie sie in der DE-AS 1 269 069 dargestellt sind. Die Abziehgreifer 12 greifen über die Rollen eines abzuziehenden Kegelrollenlagers und erfassen dadurch dieses Lager, wofür die Spindel 2 mit ihrem inneren Ende an der Stirnseite der Welle abgestützt wird, auf der das Lager sitzt. Nach dem Ansetzen sollen die Abziehgreifer den Innenring des abzuziehenden Rollenlagers über dessen Rollen hintergreifen. Zu diesem Zweck müssen die Federzungen 9 radial nach innen verstellt werden. Hierfür ist eine Spannhülse 13 vorgesehen, die im wesentlichen aus einer Druckhülse 14 und einer Stellhülse 15 besteht. Die Druckhülse 14 endet in einem Innenkonus 16, der denselben Spitzenwinkel wie die konische Mantelfläche 11 hat und dementsprechend mit seiner Innenmantelfläche 17 an der Fläche 11 spielfrei anliegt. Die Druckhülse 14 wird mittels der Stellhülse 15 axial verschoben. Hierfür ist die Stellhülse 15 mit ihrem Innengewinde 18 auf einem Außengewinde 19 des Schaftes 4 drehbar und dadurch axial verstellbar. Zur Übertragung der axialen Stellbewegung auf die Druckhülse 14 ist ein als Ringscheibe 20 ausgeführter Mitnehmer vorgesehen, der mit Preßsitz in der Stellhülse 15 angeordnet ist und an einer Schulter 21 dieser Hülse anliegt, also mit der Stellhülse drehbar ist. Beiderseits der Ringscheibe 20 liegt je eines von zwei Axial-Nadellagern 22 und 23. Der Außenring 24 des Lagers 22 ist an einer Schulter 25 der Druckhülse 14 abgestützt. Der Außenring 26 des Lagers 23 liegt an einem in die Druckhülse 14 eingesetzten Sprengring 27 an, der einen feststehenden Mitnehmer bildet und die Stellhülse nicht berührt. Ein weiterer, ebenfalls als Sprengring 28 ausgeführter Mitnehmer ist in die Stellhülse 15 nahe von deren einem Ende eingesetzt. Zwischen dem Sprengring 28 und der Ringscheibe 20 liegt ein Topfring 29, der als Staubdichtung für das Doppellager 22, 23 dient und mit dem Außenring 24 des Lagers 22 sowie mit der Mantelfläche der Druckhülse 14 einen Spalt sehr geringer Breite bildet, so daß er mit diesen Teilen nicht in Berührung ist.The withdrawal sleeve 3 is axially slotted up to close to its threaded end, so that separate tongues 9 are formed by
Im Bereich des Doppellagers 22, 23 ist in die Druckhülse 14 ein Führungsstift 30 eingesetzt, der in einem axialen Führungsschlitz 31 des Schaftes 4 gleitend geführt ist. Zwischen der Ringscheibe 20 und der Mantelfläche der Druckhülse 14 bzw. der Stirnfläche des Führungsstiftes 30 ist ein Ringspalt geringer Breite vorhanden, so daß dort keine Flächenberührung besteht.In the area of the double bearing 22, 23, a guide pin 30 is inserted into the
Beim Drehen der Stellhülse 15 im Gewinde 18, 19 werden die beiden Mitnehmer 20 und 28 sowie der zwischen ihnen verspannte Topfring 29 mitgedreht. Diese Drehbewegung wird an den Lagern 22 und 23 aufgenommen, wobei die Wälzkörper dieser Lager auf den feststehenden Außenringen 24 und 26 abrollen. Die gleichzeitig auftretende axiale Schubkraft zum Schließen der Abziehhülse (in der Zeichnung nach links) wird über den Mitnehmer 20 und den Lagerring 24 auf die Schulter 25 der Druckhülse 14 übertragen, die während dieser Axialbewegung mittels der Stift-Schlitz-Führung 30, 31 axial geführt wird. In umgekehrter Richtung, also zum Öffnen der Abziehhülse, wird die axiale Schubkraft über den Mitnehmer 28, den Topfring 29, den Mitnehmer 20, den Lagerring 26 und den Mitnehmer 27 auf die Druckhülse 14 übertragen, die dabei in gleicher Weise axial geführt ist.When turning the adjusting
Die Stellhülse 15 kann von Hand gedreht werden, was durch eine Außenriffelung 32A erleichtert wird. Für den Fall, daß eine besonders große Stellkraft aufgebracht werden muß, beispielsweise wegen der Größe des abzuziehenden Lagers, sind in der Stellhülse 15 zwei Ausnehmungen 32 und 33 vorgesehen, in die ein Stellwerkzeug, beispielsweise ein Gabelschlüssel eingreifen kann. Auch in dem Gewindeeinsatz 5 sind zwei Öffnungen 34 und 35 für den Einsatz eines derartigen Hilfswerkzeuges vorgesehen. Die Abziehhülse 14 hat ebenfalls zwei Ausnehmungen 36 und 37, um im Bedarfsfall die Abziehbewegung mittels eines Hilfswerkzeuges zu unterstützen.The adjusting
