Abstract
Bei einer Vorrichtung zur Befestigung eines Stators (3) in einer Öffnung (11) eines Maschinengehäuses (2) ist erfindungsgemäß vorgesehen, dass der Stator (3) an seiner in Einsteckrichtung (12) vorderen Stirnseite (13) mindestens einen in Einsteckrichtung (12) axial vorstehenden Vorsprung (16) und das Maschinengehäuse (2) mindestens eine entgegen der Einsteckrichtung (12) offene Aussparung (15), in die der Vorsprung (16) des Stators (3) passgenau eingreift, aufweist oder umgekehrt, und dass der Stator (3) über mindestens einen radialen Gewinde- oder Spannstift (18), der in einer radialen Bohrung (19) des Maschinengehäuses (2) angeordnet ist, in der gewünschten axialen Lage zum Maschinengehäuse (2) festgeklemmt ist.In a device for fastening a stator (3) in an opening (11) of a machine housing (2), the stator (3) has at least one in the insertion direction (12) at its front end (13) in the insertion direction (12). axially projecting projection (16) and the machine housing (2) at least one against the insertion (12) open recess (15) into which the projection (16) of the stator (3) engages accurately, or vice versa, and that the stator ( 3) via at least one radial threaded or dowel pin (18) which is arranged in a radial bore (19) of the machine housing (2), in the desired axial position to the machine housing (2) is clamped.
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Befestigungsvorrichtung für einen Stator nach der Gattung des Patentanspruchs 1.The Invention is based on a fastening device for a stator according to the preamble of claim 1.
Eine
derartige Befestigungsvorrichtung ist beispielsweise durch die
Bei dieser bekannten Befestigungsvorrichtung sind am inneren Mantelumfang des Gehäuses nach innen vorstehende Längssicken, die über die gesamte Länge des zylindrischen Teils des Gehäuses verlaufen, ausgebildet. Der Stator wird durch diese vorstehenden Längssicken des Gehäuses gehalten, wobei die Längssicken wie ein Federelement wirken und den Stator im Gehäuse festklemmen. Die Klemmkraft ist dabei derart groß, dass der Stator sich nicht relativ zum Gehäuse verdrehen oder in Axialrichtung verschieben kann. Die Längssicken sind am Umfang des Gehäuses jeweils gleich weit voneinander beabstandet, sodass eine gleichmäßige Klemmkraft auf den Stator ausgeübt wird. Durch diese Formgestaltung des Gehäuses kann der Stator ohne Kleben im Gehäuse befestigt werden.at this known fastening device are on the inner shell circumference of the housing inwardly projecting longitudinal beads, over the entire length of the cylindrical part of the housing, formed. The stator is going through held these protruding longitudinal beads of the housing, wherein the longitudinal corrugations act as a spring element and the Clamp the stator in the housing. The clamping force is included so large that the stator is not relative to the housing twist or move in the axial direction. The longitudinal beads are the same distance from each other on the circumference of the housing spaced so that a uniform clamping force is exerted on the stator. Through this design of the housing, the stator without sticking in the housing be attached.
Offenbarung der ErfindungDisclosure of the invention
Erfindungsgemäß wird vorgeschlagen, den in Einsteckrichtung in das Maschinengehäuse eingesteckten Stator mittels eines oder mehrerer Vorsprünge, welche an der in Einsteckrichtung vorderen Stirnseite des Stators axial vorstehen und in entsprechende Aussparungen des Maschinengehäuses eingreifen, im Maschinengehäuse in Umfangsrichtung, d. h. tangential, zu fixieren und mittels Gewinde- oder Spannstiften radial und axial festzuspannen. Alternativ können umgekehrt die Aussparungen auch in der in Einsteckrichtung vorderen Stirnseite des Stators und die axial vorstehenden Nasen am Maschinengehäuse vorgesehen sein.According to the invention proposed, in the insertion in the machine housing inserted stator by means of one or more projections, which at the front in the insertion direction of the stator protrude axially and into corresponding recesses of the machine housing engage, in the machine housing in the circumferential direction, d. H. tangential, to fix and by means of threaded or dowel pins clamp radially and axially. Alternatively, vice versa the recesses also in the front in the insertion direction of the stator and the axially projecting lugs on the machine housing be provided.
Vorteile der erfindungsgemäßen Befestigungsvorrichtung sind:
- – kostengünstige Lösung
- – Fixierung der axialen und radialen Bewegung des Stators mit demselben Bauteil (Gewinde- oder Spannstifte)
- – Skalierbarkeit durch Bauteilwiederholung am Umfang
- – Lösbarkeit/Trennbarkeit der Materialien (Umweltschutzanforderung, Serviceanforderungen)
- – minimaler Einfluss auf magnetische Randbedingungen (minimale Störfelder)
- – Vermeidung von unterschiedlichen Materialpassungen, wie z. B. Aluminium in Stahl oder umgekehrt
- – Verwendung von Standardverbindungsmaterialien (Gewinde- oder Spannstifte)
- - cost-effective solution
- - Fixation of the axial and radial movement of the stator with the same component (threaded or dowel pins)
- - Scalability through component repetition on the circumference
- - solubility / separability of materials (environmental protection requirement, service requirements)
- - minimal influence on magnetic boundary conditions (minimal interference fields)
- - Avoidance of different material adjustments, such. As aluminum in steel or vice versa
- - Use of standard connection materials (threaded or dowel pins)
Weitere Vorteile und vorteilhafte Ausgestaltungen des Gegenstands der Erfindung sind der Beschreibung, der Zeichnung und den Ansprüchen entnehmbar.Further Advantages and advantageous embodiments of the subject invention are the description, the drawing and the claims removable.
