Description
Leicht lösbare Warm- oder Kaltschrumpfverbindung Die Erfindung betrifft eine Warm- oder Kaltschrumpfverbindung, die sich von den bekannten Ausführungen dadurch unterscheidet, daß sie leicht zu lösen und der Flächendruck des Haftsitzes einstellbar ist, so daß trotz der leichten Lösbarkeit die gleichen Kraftmomente übertragen werden können wie bei den bekannten Ausführungen. Es sind Verbindungen bekannt, bei denen geschlossene oder geschlitzte Ringe in beliebiger Anzahl mit kegeligen Flächen gegeneinanderliegen; so daß bei axialer Pressung dieser Ringe die Außenringe radial gegen die äußeren Begrenzungsflächen, z. B. einer Nabe, und die Innenringe gegen eine Welle gepreßt -#verden. Auf diese Weise wird zwischen Welle und Nabe ein Haftsitz ähnlich dem des bekannten Schrumpfsitzes erzielt, so daß die Verbindung im Gegensatz zur Keilverbindung spielfrei arbeitet. Da sich beim Spannen dieser Verbindung die Reibung in axialer Richtung dahin auswirkt, daß der erste Ringsatz, bestehend aus einem Außen- und Innenring, die höchste spezifische Radialpressung an den Begrenzungsflächen erzeugt, jeder folgende Ringsatz aber durch die Wirkung der Axialreibung eine wesentlich geringere Radialpressung ergibt, so kann durch die Vermehrung der Ringe nur eine begrenzte Vermehrung der Haftreibung erzielt werden, aber nicht die gleiche Haftreibung, als wenn alle Ringe dieselbe Rad.ialpressung erreichen wie der vorerwähnte erste Ringsatz, auf welchen die beaufschlagende Axialkraft wirkt.Easily releasable hot or cold shrink connection The invention relates to a hot or cold shrink connection that differs from the known designs differs in that it is easy to solve and the surface pressure of the adhesive fit is adjustable, so that despite the easy solvability, the same moments of force can be transferred as with the known designs. They are connections known, in which closed or slotted rings in any number with conical surfaces lie against one another; so that with axial compression of these rings the outer rings radially against the outer boundary surfaces, z. B. a hub, and the inner rings pressed against a shaft - # verden. This way, between Shaft and hub achieved a tight fit similar to that of the known shrink fit, see above that the connection works free of play in contrast to the wedge connection. Since the Tensioning this connection affects the friction in the axial direction so that the first ring set, consisting of an outer and inner ring, the highest specific Radial pressure generated on the boundary surfaces, but each subsequent ring set through the effect of the axial friction results in a much lower radial pressure, see above can only increase the static friction to a limited extent by increasing the number of rings can be achieved, but not the same static friction as if all rings are the same Rad.ialpressung achieve like the aforementioned first ring set on which the acting Axial force acts.
Mit den Mitteln der Erfindung wird eine Steigerung der Haftreibung mit dem Ergebnis erzielt, daß alle Ringe die gleiche spezifische Radialpressung erzeugen, so daß die Gesamthaftreibung linear proportional der Ringanzahl wird. Verbindungen dieser Art finden mit Vorteil bei der Übertragung hoher Kraftmomente Anwendung, z. B. als Ersatz von Vielkeilverbindungen.The means of the invention increase the static friction with the result that all rings have the same specific radial pressure so that the total static friction is linearly proportional to the number of rings. Connections of this type are advantageous when transmitting high Moments of force Application, e.g. B. as a replacement for multi-spline connections.
Erfindungsgemäß werden die miteinander zu verbindenden Teile mittelbar über eine axial verspannbare Säule geschlossener oder geschlitzter, hintereinander- oder parallel geschalteter Ringfedern in Reibungsschluß gebracht, wobei die Größe der Schrumpfspannung und damit die Größe der Haftreibung bzw. des zu übertragenden Drehmoments vermittels der Durchmesserdehnung der Außen-oder Innenfederringe vor dem Aufbringen des aufzuschrumpfenden Teils einstellbar ist. Dabei kann als axiale Begrenzung des Spannsatzes eine Kegelfläche der Welle mit der gleichen Erzeugenden wie die Kegelflächen des Spannsatzes dienen. Das Verfahren zur Anwendung dieser Warm- oder Kaltschrumpfverbindung ist dadurch gekennzeichnet, daß z. B. beim Aufschrumpfen eines Zahnrades auf eine Welle eine Ringsäule von beliebig vielen Spannsätzen, die hintereinander- oder parallel geschaltet sind, durch eine axiale Kraft so lange gespannt werden, bis alle Ringe gegen ihre radiale Begrenzung anliegen. Dann wird die Spannmutter um einen gewissen Winkel a zurückgedreht, bis das. Zahnrad wieder abgezogen werden kann. Sodann wird die Mutter wieder angezogen, und zwar um einen Winkel a +ß, wobei der Winkel ß das Maß der gewünschten Haftreibung bestimmt. Dieses Winkelmaß ß läßt sich rechnerisch und versuchsmäßig bestimmen, so daß jedes Reibungsmaß bis zum höchsten Haftreibungssitz mit Sicherheit erreicht wird, da alle Ringe die gleiche Radialpressung erfahren, wenn das Zahnrad im angewärmten Zustand über die Ringsäule geschoben .wird und beim Erkalten durch Schrumpfen alle Ringe radial gleichmäßig preßt. An Stelle des.Aufschrumpfens kann auch ein Aufpressen des Zahnrades auf die Ringsäule zur Anwendung kommen, desgleichen die Unterkühlung des Teils, auf den der andere aufgeschrumpft werden soll. Zum Lösen der Schrumpfverbindung genügt es, wenn die Mutter um den Winkel a zurückgedreht wird. Dabei entspannt sich die Ringsäule, d. h. die Außenringe verkleinern ihren Durchmesser, so daß der aufgeschrumpfte Teil mühelos abgezogen werden kann.According to the invention, the parts to be connected to one another are indirect closed or slotted via an axially braced column, one behind the other or annular springs connected in parallel brought into frictional engagement, the size the shrinkage stress and thus the size of the static friction or that to be transmitted Torque by means of the diameter expansion of the outer or inner spring washers the application of the part to be shrunk on is adjustable. It can be used as an axial Limitation of the clamping set has a conical surface of the shaft with the same generating line how the conical surfaces of the clamping set are used. The procedure for applying this Warm or cold shrink connection is characterized in that, for. B. when shrinking a gear on a shaft a ring column of any number of clamping sets that are connected in series or in parallel, by an axial force for so long be tensioned until all rings are against their radial limit. Then it will be the clamping nut turned back by a certain angle a until the gear wheel again can be deducted. Then the mother is dressed again, by one Angle a + ß, where the angle ß determines the degree of static friction desired. This Angular dimension ß can be determined arithmetically and experimentally, so that every degree of friction to the highest static friction seat is achieved with certainty, since all rings the experience the same radial pressure when the gear is heated over the The ring column is pushed and, when it cools, all the rings shrink evenly in the radial direction presses. Instead of shrinking, the gear wheel can also be pressed onto the Ring column are used, as well as the subcooling of the part on the the other is to be shrunk on. To loosen the shrink connection it is sufficient when the nut is turned back by the angle a. The ring column relaxes, d. H. the outer rings reduce their diameter, so that the shrunk part can be pulled off easily.
In der Zeichnung ist der Gegenstand der Erfindung in fünf Abbildungen jeweils im Teillängsschnitt dargestellt, während die Wellen in Teilansicht wiedergegeben sind.In the drawing, the subject matter of the invention is shown in five figures each shown in partial longitudinal section, while the waves are shown in partial view are.
Abb. 1 bis 4 zeigen Spannverbindungen mit hinteresnandergeschalteten Spannelementen, die Abb.5 eine solche mit parallel geschalteten Spannelementen.Fig. 1 to 4 show clamping connections with one behind the other Clamping elements, Fig. 5 shows one with clamping elements connected in parallel.
Bei der Ausführungsform nach Abb. i ist auf der Welle a ein Ring oder eine Nabe b aufgeschrumpft, und zwar unter Zwischenschaltung der aus den Innenringen c und den Außenringen d bestehenden Spannelemente. Die Beaufschlagung der Spannelemente c, d erfolgt durch die Mutter e, die beispielsweise mit der Welle a in Gewindeverbindung steht. Die miteinander zu verschrumpfenden Teile a und b werden in kaltem Zustand dadurch in gegenseitige Verbindung gebracht, daß die Mutter e so lange angezogen wird, bis der Widerstand gegen das weitere Anziehen anzeigt, daß alle Ringe c, d gegen ihre äußeren und inneren Begrenzungsflächen in radialer Richtung vollkommen anliegen. Die Mutter e wird sodann so weit zurückgedreht, bis die Nabe b wieder abgezogen werden kann. Jetzt wird die Mutter e erneut angezogen, und zwar so weit, daß der Außendurchmesser der Außenringe um das für den Schrumpfsitz erforderliche Übermaß größer ist als die Bohrung der Nabe b. Alsdann wird die Nabe b auf Schrumpfwärme erhitzt und über die Spannelementensäule geschoben. Beim Erkalten der Nabe b wird durch deren Zusammenziehung eine radiale Schrumpfspannung erzeugt, welche dem durch die Mutter e eingestellten Übermaß der Außenringe des Spannelements entspricht. Bei dem gezeichneten Beispiel stützt sich die Nabe b gegen eine Schulter f der Welle a ab. Die Beaufschlagung der Spannelemente kann auch durch andere Mittel, z. B. durch Sicherungsringe nach DIN 471 und 472 od. dgl., erfolgen.In the embodiment according to Fig. I , a ring or a hub b is shrunk onto the shaft a, with the interposition of the clamping elements consisting of the inner rings c and the outer rings d. The tensioning elements c, d are acted upon by the nut e, which is threadedly connected to the shaft a, for example. The parts a and b to be shrunk together are brought into mutual connection in the cold state in that the nut e is tightened until the resistance to further tightening indicates that all rings c, d radially against their outer and inner boundary surfaces Direction. The nut e is then turned back until the hub b can be removed again. Now the nut e is tightened again, to the extent that the outer diameter of the outer rings is larger than the bore of the hub b by the oversize required for the shrink fit. The hub b is then heated to shrinkage and pushed over the clamping element column. When the hub b cools, its contraction creates a radial shrinkage tension which corresponds to the oversize of the outer rings of the tensioning element set by the nut e. In the example shown, the hub b is supported against a shoulder f of the shaft a. The application of the clamping elements can also be done by other means, e.g. B. by circlips according to DIN 471 and 472 or the like., Take place.
Bei der Ausführungsform nach Abb. 2 ist zur Erreichung einer hohen Dauerfestigkeit für die Welle a die Schulter f mit einem Konus g ausgestattet, welcher die gleiche Erzeugende hat wie die Kegelschräge der Ringe c, d.In the embodiment according to Fig. 2, in order to achieve a high fatigue strength for the shaft a, the shoulder f is equipped with a cone g, which has the same generatrix as the bevel of the cone of the rings c, d.
Eine sinngemäß gleiche Ausführungsform, bei der die Nabe b fliegend aufgeschrumpft ist und somit eine Schulter an der Welle a entbehrt werden kann, zeigt Abb. 3.An essentially identical embodiment in which the hub b is overhung is shrunk and thus a shoulder on shaft a can be dispensed with, Fig. 3 shows.
Abb.4 stellt eine Schrumpfverbindung dar, bei welcher der Schrumpfsitz nicht durch Erwärmen der Nabe b herbeigeführt wird, sondern durch eine nachträgliche Abkühlung der Welle a, beispielsweise durch Kohlenstoffschnee oder ähnliche Kühlmittel. Das Verfahren wird in diesem Fall in gleicher Weise ausgeführt wie bei den Abb. i bis 3, jedoch bleiben während der Unterkühlung der Welle a die Spannelemente c, d in der Nabe b durch die Mutter e verspannt.Fig.4 shows a shrink connection in which the shrink fit is not brought about by heating the hub b, but by a subsequent one Cooling of the shaft a, for example by carbon snow or similar coolants. In this case, the procedure is carried out in the same way as in Fig. i to 3, but the clamping elements c remain during the undercooling of the shaft a, d clamped in hub b by nut e.
Bei den Ausführungsformen nach den Abb. 1 bis 4 sind die Ringe c; d der Spannelemente hintereinandergeschaltet. Abb. 5 zeigt demgegenüber die Parallelschaltung der Ringe i, h des Spannelements, jedoch ist dies, nicht Gegenstand der Erfindung.In the embodiments according to FIGS. 1 to 4, the rings c; d of the clamping elements connected in series. In contrast, Fig. 5 shows the parallel connection of the rings i, h of the tensioning element, but this is not the subject of the invention.
