Description
Die Erfindung betrifft ein Kompressoraggregat gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a compressor unit according to the preamble of
Aus der
Die bei der Herstellung und bei dem Zusammenbau des Kompressoraggregats unvermeidlichen Toleranzen in Richtung der Motorwelle zwischen dem Kurbeltrieb und dem Zylinder werden bei derartigen Kompressoraggregaten durch die zwischen diesen Teilen befindlichen Lager kompensiert. In dem oben erwähnten Stand der Technik erfolgt der Toleranzausgleich dadurch, dass Pleuel und Kolben als zwei separate Teile ausgebildet sind, die über einen Kolbenbolzen und ein Gleitlager im Pleuelauge miteinander verbunden sind. Dieses Gleitlager lässt die erforderliche axiale Verschiebung zum Toleranzausgleich zu. Diese Konstruktion ist aber wegen ihrer Mehrteiligkeit erheblich teurer als ein vergleichbarer einteiliger Taumelkolben.The inevitable in the manufacture and assembly of the compressor unit tolerances in the direction of the motor shaft between the crank mechanism and the cylinder are compensated in such compressor units by the bearings located between these parts. In the above-mentioned prior art, the tolerance compensation takes place in that the connecting rod and piston are formed as two separate parts, which are connected to each other via a piston pin and a plain bearing in the connecting rod. This slide bearing allows the required axial displacement for tolerance compensation. However, this design is much more expensive than a comparable one-piece wobble piston because of their multi-part design.
Eine theoretisch mögliche Verwendung eines preiswerten Taumelkolbens bei gleicher Befestigung der Kurbelwelle auf der Motorwelle wie beim oben beschriebenen Stand der Technik hätte den Nachteil, dass ein deutlich erhöhtes Lagerspiel im Kugellager des Pleuels vorgesehen werden müsste, damit die erwähnten Toleranzen durch eine Schiefstellung des Taumelkolbens kompensiert werden, ohne dass das Kugellager frühzeitig Schaden nimmt. Um ein montierfähiges und dauerhaft funktionsfähiges Kompressoraggregat zu erhalten, müssten in einem solchen Falle relativ große Lagerspiele vorgesehen werden.A theoretically possible use of an inexpensive wobble piston with the same attachment of the crankshaft on the motor shaft as in the above-described prior art would have the disadvantage that a significantly increased bearing clearance in the ball bearing of the connecting rod would have to be provided so that the aforementioned tolerances are compensated by a misalignment of the wobble piston without the ball bearing getting damaged early. In order to obtain a mountable and permanently functioning compressor unit, relatively large bearing clearances would have to be provided in such a case.
Ein derartiges großes Lagerspiel hat jedoch auch immer Nachteile, wie z. B. einen erhöhten Lagerverschleiß sowie eine unerwünschte Geräuschentwicklung beim Betrieb des Kompressoraggregates.However, such a large bearing clearance always has disadvantages, such. B. increased bearing wear and unwanted noise during operation of the compressor unit.
Es ist daher Aufgabe der Erfindung, ein möglichst kostengünstiges, langlebiges und geräuscharmes Kompressoraggregat sowie ein Verfahren und ein Hilfsmittel zu dessen Herstellung und Zusammenbau anzugeben.It is therefore an object of the invention to provide a cost-effective, durable and low-noise compressor unit as well as a method and an aid for its production and assembly.
Diese Aufgabe wird durch die in den Patentansprüchen 1, 8 und 9 angegebenen Ausgestaltungen der Erfindung gelöst. In den Unteransprüchen sind vorteilhafte Weiterbildungen der Erfindung angegeben.This object is achieved by the embodiments of the invention indicated in
Die Erfindung hat den Vorteil, das erforderliche Lagerspiel auf ein erheblich geringeres Maß zu reduzieren als bei bekannten Kompressoraggregaten. So konnte z. B. bei Kompressoraggregaten der Anmelderin eine Reduzierung des Mittenversatzes zwischen Pleuelaugenmitte und Zylinderlaufflächenmitte von ±0,7 μm auf ±0,4 μm und eine damit einhergehende entsprechende Reduzierung des Lagerspiels erreicht werden. Dies wiederum führt zu einer deutlich spürbaren Verringerung der Geräuschentwicklung beim Betrieb des Kompressoraggregats.The invention has the advantage of reducing the required bearing clearance to a significantly lower level than in known compressor units. So z. B. compressor units of the applicant, a reduction of the center offset between Pleuelaugenmitte and cylinder surface center of ± 0.7 microns to ± 0.4 microns and a concomitant corresponding reduction of the bearing clearance can be achieved. This in turn leads to a noticeable reduction in noise during operation of the compressor unit.
Ein weiterer Vorteil der Erfindung besteht darin, dass eine Montage des erfindungsgemäßen Kompressoraggregats auf relativ einfache und kostengünstige Weise unter Verwendung einer erfindungsgemäßen Montagehilfsvorrichtung möglich ist. Dies ermöglicht wiederum weitere Qualitätsverbesserungen an den erfindungsgemäßen Kompressoraggregaten.Another advantage of the invention is that an assembly of the compressor unit according to the invention in a relatively simple and cost-effective manner using an assembly aid according to the invention is possible. This in turn allows further quality improvements to the compressor units according to the invention.
Ein weiterer Vorteil der Erfindung besteht darin, dass eine sogenannte Monoblockbauweise des Kompressoraggregates, d. h. eine einteilige Ausführung von Zylinderkopf und Kurbelgehäuse, einfach zu realisieren ist, wodurch eine Vereinfachung der Herstellung und eine Kosteneinsparung ermöglicht wird.Another advantage of the invention is that a so-called mono-block design of the compressor unit, d. H. a one-piece design of cylinder head and crankcase, easy to implement, allowing for ease of manufacture and cost savings.
Unter Nennung weiterer Vorteile wird die Erfindung nachfolgend anhand von Ausführungsbeispielen unter Verwendungen von Zeichnungen näher erläutert.With reference to further advantages, the invention will be explained in more detail below with reference to embodiments using drawings.
