Titel der ErfindungTitle of the invention

Senkrecht angeordnete Rotor-Kurbelwellen-Kombination für einen hermetischen KältemittelverdichterVertically arranged rotor-crankshaft combination for a hermetic refrigerant compressor

Anwendungsgebiet der ErfindungField of application of the invention

Die Erfindung ist im Kältemittelverdichterbau hermetischer Bauart anwendbar.The invention is applicable to refrigerant compressor construction hermetic design.

Charakteristik des bekannten Standes der TechnikCharacteristic of the known state of the art

Es ist ein hermetischer Kältemittelverdichter mit einem unteihalb des Stators gelegenen Motortragteil und über dem Stator angeordneter Verdichtungseinheit bekannt gemacht worden, bei dem der Rotor über eine, in ihm eingepreßte Buchse, beweglich auf einer im Motortragteil fest eingepreßten Achse angeordnet ist.A hermetic refrigerant compressor has been disclosed having an engine support member located outside of the stator and a compression unit disposed above the stator, wherein the rotor is movably mounted on an axle press-fitted in the motor support via a bushing press fitted therein.

Diese Lösung hat neben den vielen Vorteilen einer Neugestaltung der Bauteile und Reduzierung der Bauhöhe den Nächteil, daß das Lager für die eingepreßte Achse relativ lang sein muß, um einen gleichmäßigen Luftspalt zwischen Rotor und Stator über die Gesamthöhe des Motors zu erreichen. Weiterhin ist nachteilig, daßThis solution has next to the many advantages of redesigning the components and reducing the height of the next part, that the bearing for the pressed-axis must be relatively long in order to achieve a uniform air gap between the rotor and stator over the total height of the engine. Furthermore, it is disadvantageous that

das bisher bewährte Prinzip der ölumlaufkühlung nur mit Einschränkungen zur Anwendung kommen konnte.The previously proven principle of oil circulation cooling could only be used with restrictions.

Ziel der ErfindingObjective of the invention

Ziel der Erfindung ist es, eine weitere Reduzierung der Bauhöhe bei gleichzeitiger Verringerung der Lagerbelastungen mit deren energetischen Vorteilen zu erreichen.The aim of the invention is to achieve a further reduction of the height while reducing the bearing loads with their energetic benefits.

Darlegung des Wesens der ErfindungExplanation of the essence of the invention

Aufgabe der Erfindung ist es, eine verbesserte Lagerausfuhrung für das Hauptlager eines hermetischen Kältemittelverdichters eingang genannter Bauart durch eine Vergrößerung des Abstandes der Lagerflächen der Kurbelwelle im Hauptlager zueinander zu schaffen.The object of the invention is to provide an improved Lagerausfuhrung for the main bearing of a hermetic refrigerant compressor input type mentioned by increasing the distance of the bearing surfaces of the crankshaft in the main bearing to each other.

Erfindungsgemäß wird das dadurch erreicht, daß eine senkrecht angeordnete Rotor-Kurbelwellen-Kombination vorgeschlagen wird, bei der der Rotor des Einphasen-Asynchron- !iiotore in der Ebene des Axiallagers der Kurbelwelle direkt mit dieser verbunden ist.According to the invention this is achieved in that a vertically arranged rotor-crankshaft combination is proposed in which the rotor of the single-phase asynchronous! Iiotore in the plane of the thrust bearing of the crankshaft is directly connected to this.

Mit dieser Rotor-Kurbelwellen-Kombination wird das vorteilhafte System der in das Hauptlager einsteckbaren Kurbelwelle für ein unterhalb des Stators angeordnetes Motortragteil erreicht. Die maximale Legerlnnge ergibt sich aus dem Abstand der Ebene des Axiallagers und der EintaucheLene des Lagerstumpfes des Motorträgers ins öl. Innerhalb dieses Bereiches können die Lagerflächen des Schaftes der Kurbelwelle und deren Abstand zueinander in Abhängigkeit der Belastungen optimiert werden.With this rotor-crankshaft combination, the advantageous system of the crankshaft which can be inserted into the main bearing is achieved for an engine support part arranged below the stator. The maximum length is determined by the distance between the plane of the thrust bearing and the immersion plane of the bearing stub of the engine mount into the oil. Within this range, the bearing surfaces of the shaft of the crankshaft and their distance from one another can be optimized depending on the loads.

Ein weiterer Vorteil wird durch die dadurch uneingeschränkte Anwendung der (!!umlaufkühlung erreicht.Another advantage is achieved by the unrestricted use of (circulating).

Ausführungsbeispielembodiment

Die Erfindung wird nachstehend am Beispiel der Zeichnung beschrieben. Die Zeichnung zeigt einen hermetischen Kältemittelverdichter im Schnitt.The invention will be described below using the example of the drawing. The drawing shows a hermetic refrigerant compressor in section.

Der hermetische Kältemittelverdichter besteht aus Kapsel 1 und Verdichterblock 2. Der Verdichterblock 2 ist durch Stützfedern 3 und 3 a in der Kapsel federnd gelagert. Die federnde Stützeinrichtung ist gleichzeitig Teil des Ansaugweges des verdampften Kältemittels. Auf den Stützfedern 3 ist das innerhalb des Stators 4 angeordnete Motortragteil 5 abgestützt. Das Motortragteil 5 ist mit dem Stator 4 durch Schrauben verbunden. Zentrum des Motortragteiles 5 ist das Hauptlager 6 mit seinem Lagerhals 7. Der Lagerhale 7 ist im oberen Bereich so auszubilden, daß die Endfläche das Axiallager 8 für die Kurbelwelle 9 bildet. Die Kurbelwelle 9 wird in dieser Ebene mit dem Rotor 10 fest verbunden und bildet mit diesem ein Kombinationsteil. Der Vorteil der Erfindung liegt vor allem darin, daß die Kurbelwelle 9 mit dem Rotor 10 ein Bauteil bildet, das den Freiraum 11, der durch den oberen Wickelkopf 12 bestimmt ist, voll ausnutzt.The hermetic refrigerant compressor consists of capsule 1 and compressor block 2. The compressor block 2 is resiliently supported by support springs 3 and 3 a in the capsule. The resilient support means is also part of the suction path of the vaporized refrigerant. On the support springs 3, the arranged within the stator 4 motor support member 5 is supported. The motor supporting part 5 is connected to the stator 4 by screws. Center of the motor support member 5 is the main bearing 6 with its bearing neck 7. The bearing neck 7 is in the upper region in such a way that the end face forms the thrust bearing 8 for the crankshaft 9. The crankshaft 9 is firmly connected in this plane with the rotor 10 and forms with this a combination part. The advantage of the invention lies in the fact that the crankshaft 9 with the rotor 10 forms a component that fully exploits the free space 11, which is determined by the upper winding head 12.

Diese Anordnung, die auch das notwendige Axiallager 8 direkt an die Rotor-Kurbelwellen-Kombination bringt, verringert entscheidend die Gesamthöhe des Verdichterblockes 2, bei Beibehaltung einer im üblichen Sinne ausgelegten Kurbelwelle 9 für die Schmierung und die ölumlaufkühlung.This arrangement, which also brings the necessary thrust bearing 8 directly to the rotor-crankshaft combination, significantly reduces the overall height of the compressor block 2, while maintaining a designed in the usual sense crankshaft 9 for lubrication and oil circulation cooling.
