Abstract

A clamping mechanism for the rotor windings of a four or higher poled machine with a salient pole rotor. The clamping mechanism consists of a rigid clamping section (3) in the shape of a flat plate, with a tensioning bolt (4) through a cut-out in the plate. There is also an angled bracket which can be put on the tension, which is made from a flexible material such as, for example, sheet metal. The angled bracket is up against the winding (2) and has its free end clamping against the pole shoes (1), and the clamping bolt (4) is used to hold the clamping section in position. The edges of the plate in the longitudinal direction of the rotor are bent so that they are located against the angled bracket.

Description

Vorrichtung zur Abstützung der Läuferwicklung einer vier- oder höherpoligen Maschine mit Schenkelpolläufer.Device for supporting the rotor winding of a four-pole or higher pole Machine with salient pole rotor.

Die Erfindung betrifft eine Vorrichtung zur Abstützung der Schenkelpol-Läuferwicklung einer vier- oder höherpoligen Maschine, die ein Abheben der Läuferwicklung durch die Zentrifugalkraft verhindert. Bisher geschah dies z.B. durch Eindrücken von Winkelstücken aus gehärtetem Federstahl zwischen die Polschuhe. Dies setzt jedoch sehr genau eingehaltene Wicklungsabmessungen voraus, damit das Winkelstück fest genug sitzt. Gegebenenfalls müssen zur Schaffung dieser Voraussetzung FUllstoffe zwischen Wicklung und Winkelstück verwendet werden, die einen zusätzlichen Material- und Arbeitsaufwand bedingen und die Wärmeabfuhr verschlechtern. Eine andere bekannte Art, daß Abheben der Wicklung zu verhindern besteht darin, daß man Winkelstücke mittels in das Blechpaket eingedrehter Schrauben befestigt. Dies hat den Nachteil, daß Wickelraum durch die Schrauben verlorengeht.The invention relates to a device for supporting the salient pole rotor winding a four-pole or higher-pole machine that causes the rotor winding to lift off the centrifugal force prevents. So far, this has been done e.g. by pressing in contra-angles made of hardened spring steel between the pole pieces. However, this is very precisely followed Winding dimensions ahead so that the contra-angle is tight enough. Possibly To create this requirement, fillers must be placed between the winding and the elbow which require additional material and labor and worsen the heat dissipation. Another known way that lifting off the winding to prevent consists in the fact that one angle pieces by means of screwed into the laminated core Screws fastened. This has the disadvantage that winding space is lost through the screws.

Die Erfindung vermeidet die genannten Nachteile durch eine Vorrichtung zur Abstützung der Läuferwicking, die aus einem gegen die Wicklung sowie mit seinen freien Schenkelenden klemmend gegen die Polschuhe anliegenden, verspannbaren Winkelstück besteht, das über eine in eine Gewindebohrung des Winkel stückes eingreifende Spannschraube mit einem starren Klemmteil verbunden ist. Die erfindungsgemäße Vorrichtung besteht also aus einen dreiteiligen Spannsatz, der sich befestigen läßt, ohne daß genau eingehaltene Wicklungsabmessungen notwendig sind und ohne daß das Blechpaket angebohrt werden muß.The invention avoids the disadvantages mentioned by means of a device to support the rotor winding, which consists of one against the winding as well as with its free leg ends clamping against the pole shoes, braced elbow consists, the piece engaging in a threaded hole in the elbow clamping screw is connected to a rigid clamping part. The device according to the invention consists thus from a three-part clamping set that can be attached without being precise compliance with winding dimensions are necessary and without drilling into the laminated core must become.

Die erfindungsgemäße Vorrichtung ist anhand der Zeichnung in einem Ausführungsbeispiel erläutert. Dabei zeigt die Zeichnung einen vierpoligen Schenkelpolläufer in Seitenansicht, teilweise geschnitten.The device according to the invention is based on the drawing in one Embodiment explained. The drawing shows a four-pole salient pole rotor in side view, partially cut.

Mit 1 sind die Polschuhe des Läufers und mit 2 ist die Wicklung desselben bezeichnet. Der erfindungsgemäße Spannsatz besteht aus einem starren Klemmteil 3 in Form einer Platte, einer in einer Ausnehmung dieser Platte 3 sitzenden Spannschraube 4 sowie einem verspannbaren, also aus nachgiebigem Werkstoff, wie beispielsweise Blech, bestehendem Winkelstück 5. Die in Längsrichtung des Läufers verlaufenden Ränder 3' der Platte sind so abgebogen, daß sie gegen das Winkelstück 5 anliegen. Die Spannschraube 4 greift in eine Gewindebohrung des Winkelstückes ein.With 1 are the pole pieces of the rotor and with 2 is the winding same designated. The clamping set according to the invention consists of a rigid clamping part 3 in the form of a plate, a clamping screw seated in a recess of this plate 3 4 and a clampable, so made of flexible material, such as Sheet metal, existing angle piece 5. The ones running in the longitudinal direction of the runner Edges 3 'of the plate are bent so that they rest against the angle piece 5. The clamping screw 4 engages in a threaded hole in the angle piece.

Der Spannsatz 3, 4, 5 wird zwischen den Polschuhen 1 gegen die Wicklung 2 gedrückt und die Schraube 4 wird so lange angezogen, bis das Winkelstück 5 durch Verspannung fest zwischen den Polschuhen sitzt. Es ist somit ein fester Halt der Wicklung gegen Abhebenduri Zentrifugalkraft gewährleistet.The clamping set 3, 4, 5 is between the pole pieces 1 against the winding 2 pressed and the screw 4 is tightened until the angle piece 5 through Bracing sits firmly between the pole pieces. It is therefore a firm hold on the Winding against lift-off centrifugal force guaranteed.

Bei kürzeren Maschinentypen wird es genügen jeweils zwischen zwei Polschuhen einen Spannsatz anzubringen. Bei längeren Maschinen können zwei oder mehr Spannsätze je Pollücke vorgesehen werden.With shorter machine types, it will suffice between two To attach a clamping set to pole pieces. For longer machines, two or more clamping sets per pole gap can be provided.
