Description

Zahnrad für eine spielfreie StirnradstufeGear for a play-free spur gear stage

Technisches GebietTechnical field

Die Erfindung bezieht sich auf ein Zahnrad für eine spielfreie Stirnradstufe mit einer Nabe, mit einem von der Nabe getragenen Zahnkranz, der entlang einer achsnormalen Teilungsebene in zwei Teilkränze, nämlich in einen nabenfesten Kranzteil und in einen diesem gegenüber koaxial drehbar gelagerten Kranzring, geteilt ist, und mit einer in Umfangsrichtung des Zahnkranzes wirksamen Federanordnung aus über den Umfang rotationssymmetrisch verteilten Federelementen, die sich jeweils an den beiden Teilkränzen abstützen.The invention relates to a gear wheel for a backlash gear stage with zero play, with a toothed ring carried by the hub, which is divided into two partial rings along an axis-normal dividing plane, namely into a ring part fixed to the hub and into a ring ring which is rotatably mounted coaxially with respect thereto, and with a spring arrangement which is effective in the circumferential direction of the toothed ring and consists of spring elements which are distributed rotationally symmetrically over the circumference and which are each supported on the two partial rings.

Stand der TechnikState of the art

Um eine spielfreie Stirnradstufe zur Übertragung wechselnder Drehmomente zu erhalten, werden Zahnräder mit einem entlang einer achsnormalen Teilungsebene geteilten Zahnkranz eingesetzt, wobei die beiden Teilkränze, ein nabenfester Kranzteil und ein gegenüber diesem Kranzteil koaxial drehbarer Kranzring, gegeneinander federnd verspannt werden, so daß beim Eingriff eines solchen geteilten Zahnkranzes in ein Gegenrad sich die beiden Teilkränze federnd an die gegenüberliegenden Zahnflanken der Zähne des Gegenrades spielfrei anlegen. Die gegenseitige federnde Verspannung der beiden Teilkränze wird beispielsweise durch eine die Nabe des Zahnrades umschließende Ringfeder erreicht, die sich mit ihren beiden Enden an axialen Stiften einerseits des nabenfesten Kranzteiles und anderseits des Kranzringes unter einer entsprechenden Vorspannung abstützt. Aufgrund von Herstellungstoleranzen und elastischen Deformationen der Zähne kann es während des Betriebes solcher spielfreier Stirnradstufen zu einer Relativbewegung der beiden Teilkränze des geteilten Zahnkranzes kommen, was zu einer Verschleißbelastung insbesondere des auf der Nabe drehbar gelagerten Kranzringes führt. Darüber hinaus be- dingt die Vorspannung der Ringfeder einen einseitigen Kraftangriff auf den drehbar auf der Nabe gelagerten Kranzring über den in diesen Kranzring eingesetzten axialen Stift, so daß die radialen Lagerkräfte im wesentlichen nur in einem Umfangsabschnitt des Kranzringes auftreten. Dazu kommt noch, daß die aus den jeweiligen Zahnkräften und der Federkraft resultierenden Lagerkräfte sich während eines Zahnradumlaufes periodisch ändern, was sich verschleißverstärkend auswirkt.In order to obtain a play-free spur gear stage for the transmission of alternating torques, gears are used with a sprocket divided along an axially normal parting plane, the two sprockets, a hub-fixed ring part and a ring ring which can be rotated coaxially with respect to this ring part, being resiliently braced against one another, so that when one engages such a split ring gear in a mating wheel, the two ring gears resiliently rest against the opposite tooth flanks of the teeth of the mating wheel. The mutual resilient bracing of the two sub-rings is achieved, for example, by an annular spring enclosing the hub of the gear, which is supported with its two ends on axial pins on the one hand of the hub-fixed ring part and on the other hand of the ring ring under a corresponding preload. Due to manufacturing tolerances and elastic deformations of the teeth, a relative movement of the two partial rings of the split toothed ring can occur during the operation of such backlash-free spur gear stages, which leads to wear, in particular, of the ring ring rotatably mounted on the hub. In addition, the pretension of the ring spring causes a one-sided application of force on the ring ring rotatably mounted on the hub via the axial pin inserted into this ring ring, so that the radial bearing forces occur essentially only in a peripheral section of the ring ring. In addition, the bearing forces resulting from the respective tooth forces and the spring force change periodically during a gearwheel revolution, which has a wear-increasing effect.

Können die Federkräfte durch eine rotationssymmetrische Verteilung der Federelemente über den Umfang des Zahnkranzes aufgehoben werden, so ergibt sich eine rotationssymmetrische Einleitung der Federkräfte auf den Kranzring mit der Wirkung, daß die Lagerkräfte für den Kranzring - sieht man von einer Gewichtsbelastung ab - nur durch die Zahnkräfte bestimmt werden, die über den Umfang als konstant angenommen werden können. Dies bedeutet, daß sich die Lagerkräfte nicht nur über den gesamten Umfang des Kranzringes verteilen, sondern auch während eines Zahnradumlaufes keinen periodischen Schwankungen unterworfen sind, was eine wesentliche Voraussetzung für ein vorteilhaftes Verschleißverhalten des Kranzringes darstellt. Eine rotationssymmetrische Verteilung der Federelemente über den Umfang des Zahnkranzes eines Ketten- oder Zahnriemenrades ist bekannt (FR 2 805 327 A1). Zu diesem Zweck werden Schraubenfedern je in eine Umfangsausnehmung des einen Teilkranzes eingesetzt, wobei der andere Teilkranz in diese Umfangsausnehmungen axial vorstehende Stützanschläge für die Schraubenfedern aufweisen. Nachteilig bei dieser bekannten Konstruktion ist der Konstruktionsaufwand, der durch das Vorsehen von paarweise in Umfangsrichtung hintereinander liegenden Stützanschlägen für die Schraubenfedern bestimmt wird, zumal der eine Stützanschlag der Anschlagpaare durch die Umfangsausnehmung gebildet wird, die den anderen Stützanschlag aufnimmt.If the spring forces can be canceled out by a rotationally symmetrical distribution of the spring elements over the circumference of the ring gear, this results in a rotationally symmetrical introduction of the spring forces onto the ring ring with the effect that the bearing forces for the ring ring - apart from a weight load - only result from the tooth forces can be determined that can be assumed to be constant over the scope. This means that the bearing forces are not only distributed over the entire circumference of the crown ring, but are also not subject to periodic fluctuations during a gearwheel revolution, which is an essential prerequisite for advantageous wear behavior of the crown ring. A rotationally symmetrical distribution of the spring elements over the circumference of the ring gear of a chain or toothed belt wheel is known (FR 2 805 327 A1). For this purpose, coil springs are each inserted into a circumferential recess of one partial ring, the other partial ring having axially protruding support stops for the coil springs in these circumferential recesses. A disadvantage of this known construction is the construction effort, which is determined by the provision of support stops for the coil springs lying one behind the other in pairs in the circumferential direction, especially since the support stop of the stop pairs is formed by the peripheral recess which receives the other support stop.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt somit die Aufgabe zugrunde, ein Zahnrad für eine spielfreie Stirnradstufe der eingangs geschilderten Art so auszugestalten, daß eine er- heblich Konstruktionsvereinfachung erreicht werden kann, ohne die Verschleißbelastung des Kranzringes nachteilig zu beeinflussen.The invention is therefore based on the object of designing a gear for a backlash-free spur gear stage of the type described at the outset in such a way that a considerable simplification of the design can be achieved without adversely affecting the wear on the collar ring.

Die Erfindung löst die gestellte Aufgabe dadurch, daß die aus elastomeren Federkörpern bestehenden Federelemente auf einem die Nabe umschließenden Ring vorgesehen sind und an Stützanschlägen des Kranzringes angreifen.The invention achieves the stated object in that the spring elements consisting of elastomeric spring bodies are provided on a ring surrounding the hub and act on support stops of the ring ring.

Durch das Zusammenfassen der einzelnen elastomeren Federkörper über den Ring zu einer Baueinheit werden zunächst einfache Voraussetzungen für die Montage geschaffen, weil die einzelnen Federkörper nicht je für sich zwischen Stützanschlägen der beiden Kranzteile eingesetzt werden müssen. Der mit der Nabe drehfest verbundene Ring macht außerdem Stützanschläge auf dem nabenfesten Kranzteil überflüssig, wodurch der Konstruktionsaufwand merklich verringert werden kann. Die zwischen den Kranzteilen wirksamen Federkräfte heben sich aufgrund der rotationssymmetrischen Einleitung der Federkräfte auf den Kranzring wieder auf, so daß die Zahnkräfte für die Lagerkräfte des Kranzringes bestimmend werden.By combining the individual elastomeric spring bodies via the ring to form a structural unit, simple prerequisites for assembly are initially created, because the individual spring bodies do not have to be inserted between support stops of the two ring parts. The ring, which is connected to the hub in a rotationally fixed manner, also makes support stops on the hub-fixed rim part superfluous, as a result of which the construction effort can be markedly reduced. The spring forces acting between the ring parts cancel each other out due to the rotationally symmetrical introduction of the spring forces onto the ring ring, so that the tooth forces are determining for the bearing forces of the ring ring.

Weg zur Ausführung der ErfindungWay of carrying out the invention

Das Zahnrad gemäß dem dargestellten Ausführungsbeispiel weist eine Nabe 1 und einen Zahnkranz 2 auf, der entlang einer zur Zahnradachse senkrechten Ebene in zwei Teilkränze, einen nabenfesten Kranzteil 3 und einen Kranzring 4, unterteilt ist. Der Kranzring 4 ist drehbar auf der Nabe 1 gelagert und wird durch einen Spannring 5 auf der Nabe 1 axial festgehalten. Um die beiden Teilkränze 3, 4 des Zahnkranzes 2 gegenseitig federnd zu verspannen, sind zwischen den Teilkränzen 3 und 4 Federelemente 6 vorgesehen, die in Um- fangsrichtung des Zahnkranzes 2 wirksam sind und eine rotationssymmetrische Verteilung über den Umfang der Teilkränze 3, 4 aufweisen.The gear according to the illustrated embodiment has a hub 1 and a ring gear 2, which is divided along a plane perpendicular to the gear axis into two partial rings, a hub part 3 and a ring ring 4. The ring 4 is rotatably mounted on the hub 1 and is held axially on the hub 1 by a clamping ring 5. To the two To brace partial rings 3, 4 of the ring gear 2 with respect to one another, spring elements 6 are provided between the partial rings 3 and 4, which are effective in the circumferential direction of the ring gear 2 and have a rotationally symmetrical distribution over the circumference of the partial rings 3, 4.

Diese Federelemente 6 bestehen aus elastomeren Federkörpern 7, die auf einem die Nabe 1 umschließenden Ring 8 angeordnet sind und mit Stützanschlägen 9 des Kranzringes 4 zusammenwirken. Diese Stützanschläge 9 ragen axial gegen den nabenfesten Kranzteil 3 vor, so daß sich die elastomeren Körper 7, die über den Ring 8 drehfest mit der Nabe 1 verbunden sind, unter einer Vorspannung an die Stützanschläge 9 anlegen, wodurch auf die beiden Teilkränze 3, 4 ein gegensinniges Drehmoment ausgeübt wird, das ein Anlegen der Zähne der beiden Teilkränze 3, 4 an die einander gegenüberliegenden Zahnflanken eines Gegenrades 10 bewirkt, das in der Fig. 2 strichpunktiert angedeutet ist.These spring elements 6 consist of elastomeric spring bodies 7, which are arranged on a ring 8 surrounding the hub 1 and cooperate with support stops 9 of the ring ring 4. These support stops 9 project axially against the hub-fixed rim part 3, so that the elastomeric bodies 7, which are non-rotatably connected to the hub 1 via the ring 8, bear against the support stops 9 under a pretension, as a result of which the two partial rings 3, 4 an opposing torque is exerted, which causes the teeth of the two partial rings 3, 4 to bear against the opposing tooth flanks of a counter gear 10, which is indicated by dash-dotted lines in FIG. 2.

Wegen der rotationssymmetrischen Anordnung der Federelemente 6 wird der drehbar auf der Nabe 1 gelagerte Kranzring 4 über die Federelemente 6 lediglich mit einem Drehmoment, nicht aber mit resultierenden radialen Kräften aus diesen Federbelastungen beaufschlagt. Dies bedeutet, daß die Lagerkräfte zwischen dem Kranzring 4 und der Nabe 1 im wesentlichen durch die jeweils wirksamen Zahnkräfte im Eingriffsbereich des Zahnkranzes 2 mit dem Gegenrad 10 bestimmt werden und sich daher während eines Umlaufes des Zahnkranzes 2 nicht ändern. Die damit erreichte, über den Umfang während eines Umlaufes gleichbleibende radiale Belastung des Kranzringes 4 stellt eine wesentliche Voraussetzung für einen geringen Verschleiß des Kranzringes 4 im Bereich seiner Gleitfläche dar. Because of the rotationally symmetrical arrangement of the spring elements 6, the ring ring 4, which is rotatably mounted on the hub 1, is only acted upon by the spring elements 6 with a torque, but not with resulting radial forces from these spring loads. This means that the bearing forces between the ring gear 4 and the hub 1 are essentially determined by the respectively effective tooth forces in the area of engagement of the ring gear 2 with the counter gear 10 and therefore do not change during a rotation of the ring gear 2. The radial load of the ring ring 4 that is achieved over the circumference during a revolution is an essential prerequisite for low wear of the ring ring 4 in the region of its sliding surface.
