Abstract
Description
Die Erfindung betrifft ein Gehäuse für elektrische Maschinen, insbesondere für höhere Schutzarten wie z.B. IP67. Diese Gehäuse zumeist Aluminiumkreuzprofile müssen mit dem Blechpaket des Stator verbunden werden. Dies geschieht insbesondere durch Warmschrumpfen. An das Gehäuse werden anschließend Zentrierränder gedreht, um Lagerschilde und Flansche montieren zu können. Die Flansche werden dann mit langen Schrauben an oder durch das Gehäuse montiert.The The invention relates to a housing for electrical Machines, especially for higher Protection types such as IP67. These housings mostly aluminum cross profiles have to be connected to the laminated core of the stator. This happens in particular by Heat shrinking. To the case will be afterwards spigots turned to mount end shields and flanges. The Flanges are then mounted on or through the housing with long screws.
Der Erfindung liegt die Aufgabe zugrunde, eine Verbindungsart von Gehäuse und Stator zu schaffen, die weniger zeit- und montageaufwendig ist, als auch weniger Arbeitsschritte erfordert.Of the Invention is based on the object, a connection of housing and To create a stator that is less time consuming and assembly consuming, as well as fewer steps required.
Die Lösung der gestellten Aufgabe gelingt durch ein Verfahren nach Anspruch 1 und eine Vorrichtung nach Anspruch 3.The solution the task is achieved by a method according to claim 1 and a device according to claim 3.
Dabei wird der fertiggedrehte AS-Lagerschild und der BS-Flansch sowie das Blechpaket des Stators in eine Vorrichtung eingelegt. Diese Teile sind dabei zueinander ausgerichtet. Anschließend wird ein dünnwandiges Rohr, vorzugsweise ein Aluminiumrohr, mit der Dicke von 1 bis 3 mm axial darübergeschoben. Durch Magnetumformung wird das Aluminiumrohr an die Kontur des Blechpakets des Stators und der Flansche angepresst. Die auf das Rohr wirkenden Kräfte sind radial nach innen gerichtet und pressen es auf das Blechpaket. In den Lagerschilden und/oder Flanschen sind vorteilhafterweise umlaufende Sicken, die einen Formschluss mit dem Gehäuse ergeben.there is the finished rotated AS bearing plate and the BS flange and the Laminated core of the stator inserted in a device. These parts are aligned with each other. Subsequently, a thin-walled Tube, preferably an aluminum tube, with the thickness of 1 to 3 mm axially pushed over. Magnetic forming turns the aluminum tube to the contour of the laminated core of the stator and the flanges pressed. The ones acting on the pipe personnel are directed radially inwards and press it on the laminated core. In the end shields and / or flanges are advantageously circumferential beads, which result in a positive connection with the housing.
Das Magnetumformen ist ein elektrodynamisches Hochgeschwindigkeitsverfahren mit dem sich elektrisch gut leitfähige Materialien berührungslos kalt verformen lassen. Das Umformen erfolgt durch die Krafteinwirkung eines impulsartigen Magnet feldes sehr hoher Intensität. Das Magnetfeld übt auf das stromdurchflossene Teil einen starken magnetischen Druck aus. Sobald dieser die Fließspannung des verwendeten Werkstoffs überschreitet, formt er das Teil innerhalb von Mikrosekunden bleibend um.The Magnetic forming is a high-speed electrodynamic process with the electrically good conductive materials contact cold deform. The forming takes place by the force a pulse-like magnetic field very high intensity. The magnetic field exerts on the current flowing through Part of a strong magnetic pressure. Once this is the yield stress exceeds the material used, It reshapes the part within microseconds.
Das Magnetumformen eignet sich für alle plastisch umformbaren und elektrisch leitfähigen Werkstoffe, wie z.B. Kupfer und Aluminium andere Leitmetalle sowie deren Legierungen.The Magnetic forming is suitable for all plastically deformable and electrically conductive materials, e.g. Copper and aluminum other conductive metals and their alloys.
Durch das erfindungsgemäße Verfahren entsteht eine Verbindung von Gehäuse und Stator bzw. Flanschen die luft- und wasserdicht ist.By the inventive method creates a connection of housing and stator or flanges which is air and waterproof.
Das Blechpaket des Stators kann auch als Kreuzprofil ausgeführt werden, um das axiale Anflanschen der elektrischen Maschine an eine Arbeitsmaschine zu ermöglichen; dabei ist eine freie Schraubenzugänglichkeit notwendig.The Laminated core of the stator can also be designed as cross profile, to the axial flanging of the electric machine to a working machine to enable; while a free screw accessibility is necessary.
Auch wenn das Blechpaket des Stators nach außen ragende Kühlrippen aufweist, kann das Gehäuse durch die oben aufgeführten Schritte durch Magnetumformen hergestellt werden. Es sind somit keine spanenden Bearbeitungen am fertigen Stator notwendig. Die Gehäuseschrauben aus bisher bekannten Herstellungsverfahren entfallen, es steht somit mehr Raum für die Wicklung zur Verfügung, dadurch ist auch eine kurze Bauweise einer elektrischen Maschine möglich.Also if the laminated core of the stator outwardly projecting cooling fins has, the housing can through the above Steps are made by magnetic forming. There are no machining operations on the finished stator necessary. The housing screws omitted from previously known manufacturing processes, it is therefore more room for the winding available This is also a short design of an electrical machine possible.
