Abstract

A conveying unit having a pump chamber in which a rotor is mounted in a rotatable manner, and which is formed by a circumferential wall and two end walls, is already known. The circumferential wall is formed on an annular collar of a pump part and, on the inside, forms a track on which sealing bodies of a rotor roll. The track of the pump chamber is subjected to high compressive loading which, if the pump part is made of plastic, may result in the track rupturing. In the case of the conveying unit according to the invention, the pump part is improved in respect of strength and service life. Deformation of the pump part by hydraulic forces or by pressing-in forces is avoided. The invention provides that ribs (34) are arranged on the outside (33) of the circumferential wall (18), the outside being directed away from the pump chamber (12), or that arranged on that side of the end wall (20) which is directed away from the pump chamber is at least one shoulder (40) which is connected in a force-fitting manner, by means of a press fit, to the pump housing (1) and is designed with thin walls to the extent where the pressing forces do not result in any deformation to the end wall of the pump chamber (12).

However, the peripheral wall 18 can expressly also form the track 24 itself.
Am Umfang des Rotors 13 sind über den Umfang des Rotors 13 verteilt mehrere Nuten 23 angeordnet. Die Nuten 23 durchragen den Rotor 13 in axialer Richtung von einer Stirnseite des Rotors 13 zur anderen Stirnseite. Die Nuten 23 verlaufen jeweils vom Außenumfang aus nach radial innen mit zwei beispielsweise parallel zueinander angeordneten Seitenflanken und enden in einem beispielsweise bogenförmigen Nutgrund 28. In jeder Nut 27 ist ein Dichtkörper 29 vorgesehen, der beispielsweise als zylinderförmige Rolle ausgebildet ist.

Beispielsweise verlaufen sie von der dem Deckel 21 zugewandten Stirnseite des Pumpenteils 22 aus über eine vorbestimmte Länge in axialer Richtung. In radialer Richtung bezüglich der Rotorachse 16 verlaufen die Rippen 34 von der Außenseite 33 der Umfangswand 18 bis an eine Gehäusewand 32.The ribs 34 are arranged in the axial region of the pump chamber 12, for example, between the first end wall 19 and the second end wall 20. However, they can expressly extend beyond the second end wall 20. For example, they extend from the end 21 of the cover 21 of the pump part 22 over a predetermined length in the axial direction. In the radial direction with respect to the rotor axis 16, the ribs 34 extend from the outside 33 of the circumferential wall 18 to a housing wall 32.
Da die Rippen 34 zwischen der Umfangswand 18 bzw. dem Kragen 25 und dem Gehäuse 1 vorgesehen sind und die Umfangswand 18 bzw. der Kragen 25 exzentrisch bezüglich der Rotorachse 16 angeordnet ist, ergibt sich eine unterschiedliche radiale Höhe der einzelnen Rippen 34.Since the ribs 34 are provided between the peripheral wall 18 and the collar 25 and the housing 1 and the peripheral wall 18 and the collar 25 is arranged eccentrically with respect to the rotor axis 16, results in a different radial height of the individual ribs 34th
Die Rippen 34 sind über den Umfang der Umfangswand 18 bzw. des Kragens 25 verteilt, beispielsweise gleichmäßig oder ungleichmäßig und sind in Umfangsrichtung zueinander beabstandet, so dass zwischen ihnen Vertiefungen gebildet sind.The ribs 34 are distributed over the circumference of the peripheral wall 18 and the collar 25, for example, uniformly or non-uniformly and are spaced apart in the circumferential direction, so that recesses are formed between them.
Gemäß einem alternativen oder optionalen Ausführungsbeispiel ist an der der Pumpenkammer 12 abgewandten bzw. dem Aktor 14 zugewandten Seite der Stirnwand 20 zumindest eine Schulter 40 vorgesehen, die mittels einer Presspassung mit dem zylinderförmigenAccording to an alternative or optional embodiment, at least one shoulder 40 is provided on the side of the end wall 20 facing away from the pump chamber 12 or facing the actuator 14, said shoulder being provided with the cylindrical one by means of an interference fit
Pumpengehäuse 1 kraftschlüssig verbunden ist und die derart dünnwandig ausgebildet ist, dass die über die Schulter 40 eingeleiteten Presskräfte keine Verformung der Stirnwand 20 der Pumpenkammer 12 erreichen. Durch diese erfindungsgemäße Ausbildung wird verhindert, dass die Stirnwand 20 der Pumpenkammer 12 beim Einpressen des Pumpenteils 22 in das Pumpengehäuse 1 verformt wird. Hierdurch könnte eine erhöhte Reibung auf den Rotor 13 entstehen oder dieser könnte vollständig blockiert werden. Die Wanddicke s der zumindest einen Schulter 40 ist um ein Vielfaches kleiner als der Radius r des Pumpengehäuses 1 , beispielsweise 5 bis 10 mal kleiner. Die Presspassung liegt hauptsächlich im Bereich der Schulter 40 und nicht im Bereich der Pumpenkammer 12 vor, so dass die Gehäusewand 32 des Pumpengehäuses 1 außerhalb der Schulter 40 höchstens geringe Kräfte auf die Pumpenkammer 12 ausübt, die jedoch keine Verformung der Pumpenkammer 12 bewirken. Die zumindest eine Schulter 40 ist beispielsweise radial außerhalb der Pumpenkammer 12 angeordnet. Beispielsweise ist eine einzige Schulter 40 vorgesehen, die einen geschlossenen Ring bildet. Alternativ kann die Ringschulter 40 auch unterbrochen sein, so dass mehrere teilringfδrmige Schultern 40 vorhanden sind.Pump housing 1 is non-positively connected and which is formed so thin-walled that initiated via the shoulder 40 pressing forces do not reach deformation of the end wall 20 of the pump chamber 12. This inventive design prevents the end wall 20 of the pump chamber 12 is deformed during the pressing of the pump part 22 into the pump housing 1. This could cause an increased friction on the rotor 13 or this could be completely blocked. The wall thickness s of the at least one shoulder 40 is smaller by a multiple than the radius r of the pump housing 1, for example 5 to 10 times smaller. The interference fit is mainly in the region of the shoulder 40 and not in the region of the pump chamber 12, so that the housing wall 32 of the pump housing 1 outside the shoulder 40 at most low forces on the pump chamber 12 exerts, however, cause no deformation of the pump chamber 12. The at least one shoulder 40 is arranged, for example, radially outside the pump chamber 12. For example, a single shoulder 40 is provided which forms a closed ring. Alternatively, the annular shoulder 40 may also be interrupted, so that a plurality of teilringfδrmige shoulders 40 are present.
Die zumindest eine Schulter 40 weist auf der dem Pumpengehäuse 1 zugewandten Seite nicht dargestellte Längsrippen auf, die beispielsweise Fügeschrägen haben.The at least one shoulder 40 has on the side facing the pump housing 1 side not shown longitudinal ribs, for example, have Füschrrägen.
Die Ausführung mit der zumindest einen Schulter 40 kann wie in Fig.1 gezeigt in Kombination mit den erfindungsgemäßen Rippen 34 vorgesehen sein. Es ist aber ausdrücklich auch möglich, die zumindest eine erfindungsgemäße Schulter 40 auszuführen, ohne dass die erfindungsgemäßen Rippen 34 an der Umfangswand 18,25 ausgebildet sind. The embodiment with the at least one shoulder 40 may be provided as shown in Figure 1 in combination with the ribs 34 according to the invention. However, it is expressly also possible to carry out the at least one shoulder 40 according to the invention without the ribs 34 according to the invention being formed on the circumferential wall 18, 25.
