Abstract

The equipment provides a rigid coupling in the peripheral direction between the shaft of an engine or motor and that of a driven machine, while remaining resilient in the axial direction. A plate member (10) is coupled at the outer periphery to the one shaft (2) and at the centre to the other (8). The plate can be so dimensioned as to be resilient in the direction at right angles to its surface. It can also be resilient in the readial direction, having annular corrugations.

Description

Vorrichtung zur starren, umfangsspielfreien, Device for rigid, circumferential backlash-free,

aber axial nachgiebigen Wellenverbindung Die Erfindung bezieht sich auf eine Vorrichtung zur starren, umfangsspielfreien, aber axial nachgiebigen Verbindung der Welle eines Antriebsmotors mit der Welle eines angetriebenen Aggregates Die der Erfindung zugrundeliegende Aufgabe besteht darin, eine starre Verbindung zwischen den Wellen eines beispielsweise durch eine Verbrennungskraftmaschine gebildeten Antriebsmotors und eines von diesem Motor angetriebenen Aggregates, zum Beispiel eines Kompressors einer Wärmepumpenanlage oder eines Generators einer Stromerzeugungsanlage, zu schaffen, die einfach und kompakt aufgebaut ist. Diese starre Wellenverbindung soll einerseits axial nachgiebig sein, um die bei der Fertigung und Monhage auftretenden Toleranzen in Längsrichtung sowie ebenfalls in dieser Richtung wirkende, möglicherweise im Betrieb auftretende Wärmedehnungen ausgleichen zu können; zum anderen soll die Wellenverbindung aber in Umfangsrichtung spielfrei sein. but axially compliant shaft connection The invention relates to a device for a rigid, circumferential backlash-free, but axially flexible connection the shaft of a drive motor with the shaft of a driven unit Die The object of the invention is to provide a rigid connection between the waves of a formed for example by an internal combustion engine Drive motor and a unit driven by this motor, for example a compressor of a heat pump system or a generator of a power generation system, to create that is simple and compact. This rigid shaft connection on the one hand should be axially flexible to avoid those that occur during manufacture and assembly Tolerances in the longitudinal direction and also in this direction, possibly to be able to compensate for thermal expansions occurring during operation; on the other hand should the However, shaft connection must be free of play in the circumferential direction.

Die Lösung dieser Aufgabe erfolg gemäß der Erfindung durch ein plattenförmiges Element, das an seinem Außenumfang mit der einen Welle und an seinem Innenumfang mit der anderen Welle verbunden ist. Dabei kann das plattenförmige Element durch seine Bemessung in der zur Plattenebene senkrechten Richtung nachgiebig sein. Zusätzlich zu dieser axialenNachgiebigkeit kann das plattenförmige Element auch radial nachgiebig ausgebildet sein, indem es beispielsweise ringförmige Wellungen oder aber einen senkrecht zur Plattenebene verlaufenden Steg aufweist.This object is achieved according to the invention by a plate-shaped Element that on its outer circumference with a shaft and on its inner circumference connected to the other shaft. The plate-shaped element can thereby through its dimensioning must be flexible in the direction perpendicular to the plane of the plate. Additionally in addition to this axial flexibility, the plate-shaped element can also be radially flexible be formed by, for example, annular corrugations or a Has web running perpendicular to the plane of the plate.

Eine bevorzugte Ausführungsform der Erfindung sieht vor, daß das plattenförmige Element im wesentlichen dreieckförmig ausgebildet ist und an den drei Ecken mit einem auf der Welle des Antriebsmotors befestigten Flansch verbunden ist.A preferred embodiment of the invention provides that the plate-shaped Element is essentially triangular and at the three corners with is connected to a flange attached to the shaft of the drive motor.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, das im folgenden näher beschrieben wird. Die Zeichnung zeigt in Figur 1 einen Längsschnitt durch die erfindungsgemäße Wellenverbindung und Figur 2 eine Ansicht der Wellenverbindung von der Aggregateseite aus.In the drawing, an embodiment of the invention is shown, which is described in more detail below. The drawing shows a longitudinal section in FIG through the shaft connection according to the invention and FIG. 2 shows a view of the shaft connection from the aggregate side.

In der Zeichnung ist mit 1 die Wellenverbindung insgesamt, mit 2 die Kurbelwelle einer hier nicht gezeigten, als Antriebsmotor dienenden Verbrennungskraftmaschine und mit 8 die Eingangswelle eines von dem Antriebsmotor angetriebenen Aggregates, beispielsweise des Kompressors einer Wärmepumpenanlage,bezeichnet. Auf der Motorkurbelwelle 2 ist mittels Schrauben 4 ein Flansch 3 befestigt, der an seinem Außenumfang einen Ring 5 trägt, der mittels Befestigungsschrauben 7 befestigt und mittels Zentrierstiften 6 zentriert ist.In the drawing, 1 is the shaft connection as a whole, with 2 the Crankshaft of an internal combustion engine, not shown here, serving as a drive motor and with 8 the input shaft of a unit driven by the drive motor, for example, the compressor of a heat pump system, referred to. On the engine crankshaft 2, a flange 3 is fastened by means of screws 4, the one on its outer circumference Ring 5 carries, which is fastened by means of fastening screws 7 and by means of centering pins 6 is centered.

An diesem Ring 5 sind mittels dreier Schrauben 12 die drei Ecken eines in Form eines gleichseitigen Dreieckes ausgebildeten plattenförmigen Elementes 10 befestigt. Der Innenrand dieses plattenförmigen Elementes 10 ist mittels Nieten 11 mit einem Nabenteil 9 verbunden, das auf einem konischen Wellenstummel 14 der Aggregatewelle 8 unter Verwendung einer Scheibenfeder 13 und einer stirnseitigen Verschraubung 15 formschlüssig gehalten ist.On this ring 5, the three corners are one by means of three screws 12 Plate-shaped element 10 designed in the form of an equilateral triangle attached. The inner edge of this plate-shaped element 10 is by means of rivets 11 connected to a hub part 9, which is on a conical stub shaft 14 of Aggregate shaft 8 using a disc spring 13 and a front screw 15 is held positively.

Das plattenförmige Kupplungselement 10 ist in seiner Stärke so bemessen, daß es sich zum Ausgleich von Fertigungs- und Montagetoleranzen sowie von axialen Wärmedehnungen senkrecht zu seiner Ebene, d.h. in Richtung der Achsen der beiden Wellen 2 und 8, durchbiegen kann. In Umfangsrichtung wird dagegen eine spielfreie Verbindung der beiden Wellen 2 und 8 erreicht. Der wesentliche Vorteil der erfindungsgemäßen Ausbildung besteht in dem einfachen und kompakten Aufbau, der dennoch ein gewünschtes Axialspiel bei völliger Umfangsspielfreiheit gewährleistet.The plate-shaped coupling element 10 is dimensioned in its strength so that that it is to compensate for manufacturing and assembly tolerances as well as axial Thermal expansions perpendicular to its plane, i.e. in the direction of the axes of the two Shafts 2 and 8, can deflect. In the circumferential direction, however, there is a backlash-free Connection of the two shafts 2 and 8 achieved. The main advantage of the invention Training consists in the simple and compact structure, which is nevertheless a desired Axial play guaranteed with complete freedom from circumferential play.

Für den Fall, daß auch in radialer Richtung ein Ausgleich von Toleranzen beziehungsweise Dehnungen vorgenommen werden soll, kann das plattenförmige Kupplungselement auch radial nachgiebig sein, indem es beisoielsweise, wie hier nicht dargestellt ist, ringförmige Wellungen enthält. Anstelle solcher Wellungen könnte das plattenförmige Element 10 auch so ausgebildet sein, daß es innerhalb seines Verlaufes einen im wesentlichen senkrecht zur Plattenebene verlaufenden, ringförmigen Steg enthält. Auch durch eine solche Ausbildung wäre eine radiale Nachgiebigkeit der Kupplung bei Aufrechterhaltung der gewünschten Umfangsspielfreiheit und der axialen Nachgiebigkeit gesichert.In the event that tolerances are also compensated for in the radial direction or expansions are to be made, the plate-shaped coupling element also be radially compliant by, for example, not shown here is, contains annular corrugations. Instead of such corrugations, the plate-shaped Element 10 can also be designed so that it has an in its course contains substantially perpendicular to the plane of the plate, annular web. Such a design would also result in radial flexibility of the coupling while maintaining the desired freedom from circumferential backlash and axial flexibility secured.
