Stator mit Spannvorrichtung Stator with Spannvorr ichtung

Unter der Bezeichnung "Stator" ist das nicht rotierende Teil einer Exzenterschneckenpumpe zu verstehen.Called the "stator", this is the non-rotating part to understand an eccentric screw pump.

Gegenstand del' Neuerung ist ein nicht als Gummimetall-Verbindung ausgebildeter Stator aus Kautschuk, kautschukähnlichem Material oder Kunststoffen (Fig. 3), dessen Oberfläche eine oder mehrere axial verlaufende Vertiefungen (Fig. 4) sowie eine oder mehrere Nuten (Fig. 5) aufweist. Umschlossen wird der Stator (Fig. 3) /on einem Spannmantel (Fig. 1) aus Metall, Kunststoff oder ähnlichem Material, der an seiner Innenseite einen oder mehrsre Keile (Fig. 5), passend in die Nut(en) des Stators (Fig. 5) zeigt. Zwischen Spannmantel (Fig. 1) und Stator (Fig. 3) befindet sich eine aus Metall, Kunststoff oder ähnlichem Material bestehende Gleithülse (Fig. 2) in Form eines in Längsrichtung aufgeschnittenen Rohres.The subject of the innovation is a non-rubber-to-metal compound formed stator made of rubber, rubber-like material or plastics (Fig. 3), the surface of which has one or more has axially extending depressions (Fig. 4) and one or more grooves (Fig. 5). The stator is enclosed (Fig. 3) / on a clamping jacket (Fig. 1) made of metal, plastic or similar material that has one or more wedges (Fig. 5) on its inside, fitting into the groove (s) of the stator (Fig. 5) shows. Between the clamping jacket (Fig. 1) and the stator (Fig. 3) there is one made of metal, plastic or a similar material Sliding sleeve (Fig. 2) in the form of a tube cut open in the longitudinal direction.

Es gibt eine Anzahl von Statoren in mancherlei fertigungstechnischen A1 . 'ndlungen, die meistens in irgend einer Art mit einem um-εο ^. ^ eß end en Mantel verbunden sind.There are a number of stators in various manufacturing A 1 . 'ndings, which are mostly in some way with an um-εο ^. ^ Eßend en coat are connected.

Nach der Neuerung wird der Stator (Fig. 3) in bekannter Weise gefertigt und in den Spannmantel (Fig. 1) mit Gleithülse (Fig. 2) gegeben. Beim Anspannen des Spannmantels (Fig. 1), das mechanisch, hydraulisch, pneumatisch oder ähnlich geschieht, wird der Stator (Fig. 3) infolge der konstruktiv vorgegebenen Einzelheiten (Nuten Fig. 4, Keil Fig. S) so gehalten, daß er seine Leistung voll erbringen kann.According to the innovation, the stator (Fig. 3) is manufactured in a known manner and in the clamping jacket (Fig. 1) with sliding sleeve (Fig. 2) given. When tensioning the clamping jacket (Fig. 1), which happens mechanically, hydraulically, pneumatically or similar, the Stator (Fig. 3) as a result of the structurally predetermined details (grooves Fig. 4, wedge Fig. S) held so that its performance can fully provide.

Eine unvermeidbare Abnützung der Statorinnenseite beim Pumpbetrieb wird erfindungsgemäß ausgeglichen durch ein Anspannen des Spannmantels (Fig. 1), wobei die Gleithülse (Fig. 2) den Stator fest und verdrehsicher umschließt und_j?leiohzeitig dem Ausweichdrang des Statormaterials (Fig. 3) entgegen wirkt.Unavoidable wear and tear on the inside of the stator during pump operation is compensated according to the invention by tightening the tensioning jacket (Fig. 1), the sliding sleeve (Fig. 2) the stator firmly and twist-proof and encloses the urge to evade the stator material (Fig. 3) counteracts.

Nach endgültiger Abnützung des Stator-Innenprofils ist mit Leichtigkeit der Spannmantel zu öffnen und ein neuer Stator einzusetzen.After the stator inner profile has finally worn out, it is with ease to open the clamping jacket and insert a new stator.
