Abstract
Description
Die Erfindung betrifft eine Rotationsmaschine mit einem hohlzylinderförmigen Gehäuse, mindestens einer axial am Ende des Gehäuses angeordneten Gehäuseplatte und am Gehäuse und/oder an der Gehäuseplatte vorgesehenen Ein- und Auslassöffnungen, einem im Gehäuse rotierenden Rotor und wenigstens einem in einem Rotorschlitz axial oder radial und axial beweglichen, die Gehäusewand und die Gehäuseplatten an Dichtlinien oder Dichtflächen berührenden, den Raum zwischen Gehäuse und Rotor in Arbeitsräume aufteilenden Schieber oder Flügel.The invention relates to a rotary machine having a hollow cylindrical housing, at least one axially disposed at the end of the housing housing plate and provided on the housing and / or on the housing plate inlet and outlet openings, a rotor rotating in the housing and at least one in a rotor slot axially or radially and axially movable, the housing wall and the housing plates on sealing lines or sealing surfaces touching, dividing the space between the housing and rotor in working spaces slide or wing.
Stand der TechnikState of the art
Aus der
Neben erhöhtem Fertigungsaufwand entstehen hier aber zusätzliche radiale Leckagen und Toträume zwischen Flügel, Rotor und Gehäuse.In addition to increased production costs but here additional radial leakage and dead space between the wing, rotor and housing arise.
Eine axiale Verschleißnachführung ist mit diesem bekannten Stand der Technik nicht oder nur begrenzt unter Schaffung zusätzlicher Leckageherde möglich, da die Gehäuseendplatten im Wesentlichen parallel zueinander stehen.An axial wear tracking is not possible or limited with the creation of additional leakages with this known prior art, since the housing end plates are substantially parallel to each other.
Aus der
Aufgabenstellungtask
Bei diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Rotationsmaschine zu entwickeln, bei der eine Minimierung der axialen Leckagen, eine Reduzierung der Toträume und eine selbsttätige Verschleißnachführung in axialer Richtung unter gleichzeitiger Standzeiterhöhung und der Senkung der Betriebskosten ermöglicht wird.In this prior art, the present invention seeks to develop a rotary machine, in which a minimization of axial leakage, a reduction of dead space and an automatic wear tracking in the axial direction while increasing the service life and reducing the operating costs is made possible.
Diese Aufgabe wird durch eine Rotationsmaschine der eingangs genannten Gattung mit den Merkmalen des Anspruches 1 gelöst.This object is achieved by a rotary machine of the type mentioned with the features of
Vorteilhafte Ausgestaltungen der erfindungsgemäßen Rotationsmaschine sind den Unteransprüchen entnehmbar.Advantageous embodiments of the rotary machine according to the invention are the dependent claims.
Erfindungsgemäß wird das Problem durch Formgebung der axialen Gehäuseendflächen der Gehäuseplatten in Verbindung mit den jeweils entsprechenden Flügel/Schieber- und Rotorgeometrien gelöst.According to the invention, the problem is solved by shaping the axial housing end faces of the housing plates in conjunction with the respectively corresponding wing / slide and rotor geometries.
Die Gehäuseplatte ist demgemäß gehäuseinnenseitig mit mindestens einer Gehäuseendfläche versehen, die im Wesentlichen als mit einem stumpfem Öffnungswinkel und kleinem Böschungswinkel zwischen Kegelgrundfläche und Kegelmantelfläche aufweisenden Kegel oder Kegelstumpf ausgebildet ist. Die Spitze des Öffnungswinkels des Kegels oder Kegelstumpfes weist dabei vom Gehäusezentrum gesehen nach außen. Die im Wesentlichen parallele Anpassung der axialen Dichtlinien oder -flächen der Flügel/Schieber an diese Gehäuseendflächenform ermöglicht eine Nachführung des Verschleißes in axialer Richtung. Gleichzeitig erfolgt eine Verteilung der Zentripedalkräfte auf die Flügel/Schieber in Richtung Rotationszentrum entlang des Kontaktes der Flügel/Schieber mit den axialen Gehäuseendflächen. Damit verbunden erfolgt eine Verschiebung der für den Verschleiß relevanten Umfangsgeschwindigkeiten in Richtung Drehachse. Keilselbsthaftungseffekte verringern radiale Belastungen bei Lastwechseln.The housing plate is accordingly provided on the housing side with at least one housing end face, which is designed substantially as having a blunt opening angle and small slope angle between the cone base surface and conical surface having cone or truncated cone. The apex of the opening angle of the cone or truncated cone points outward from the housing center. The substantially parallel adaptation of the axial sealing lines or surfaces of the wing / slide to this housing end face allows tracking of the wear in the axial direction. At the same time, the centripetal forces are distributed to the vanes / vanes in the direction of the center of rotation along the contact of the vanes / vanes with the axial housing end faces. Associated with this, there is a displacement of the circumferential speeds which are relevant for the wear in the direction of the axis of rotation. Wedge self-adhesive effects reduce radial loads during load changes.
In weiterer Ausgestaltung der Erfindung kann die Gehäusemantelform hierbei beliebig, beispielhaft zylinderförmig mit kreisförmiger, eiförmiger oder elliptischer Grundfläche sein. Die im Wesentlichen kegelförmigen Gehäuseendflächen können Kurvenflächen aufweisen und als gerade oder schiefe Kegel ausgebildet sein, um im Zusammenwirken vor allem mit den Flügelformen eine dem Funktionszweck der Maschine entsprechende optimale Dichtung, Anlage und Nachführung des Verschleißes zu erreichen.In a further embodiment of the invention, the housing shell shape can here be arbitrary, for example cylindrical with a circular, egg-shaped or elliptical base. The substantially conical housing end faces may have cam surfaces and be designed as straight or oblique cones in order to achieve, in cooperation with the wing shapes, in particular, an optimum seal, installation and tracking of the wear for the purpose of the machine.
Nach einer weiteren bevorzugten Ausgestaltung der erfindungsgemäßen Rotationsmaschine sind die Kontaktzonen entlang der Dichtlinien oder Dichtflächen an den Schiebern oder Flügeln zum Gehäuse und den Gehäuseendflächen ganz oder teilweise aus schnell verschleißendem Material und/oder zusätzlichen Konstruktionselementen ausgeführt, um die Ausbildung der Dichtung mittels Nachführung zu beschleunigen. Das Gehäuse und die Gehäuseendflächen können zumindest teilweise aus gegenüber den Schiebern oder Flügeln schneller verschleißendem Material ausgeführt sein.According to a further preferred embodiment of the rotary machine according to the invention, the contact zones along the sealing lines or sealing surfaces on the slides or wings to the housing and the housing end surfaces are wholly or partly made of rapidly-wearing material and / or additional structural elements to accelerate the formation of the seal by means of tracking. The housing and the housing end surfaces may be at least partially made of faster material relative to the slides or vanes.
