Description
Läufer für Elektromotor Die Erfindung betrifft einen Läufer für Elektromotoren bei dem zwischen dem Blechpaket, dem Kollektor und den Kugellagern auf der Welle ein Kleber oder ein aushärtender Fullstoff angeordnet ist. Rotor for electric motor The invention relates to a rotor for electric motors between the laminated core, the collector and the ball bearings on the shaft an adhesive or a hardening filler is arranged.
Um einen guten Sitz des Läuferblechpaketes auf der Welle zu erreichen ist es bekannt, zwischen Welle und Blechpaket einen Kleber anzuordnen. Der Erfindung liegt die Aufgabe zugrunde, die Verbindung des Blechpaketes mit der Läuferwelle mittels Kleber zu vereinfachen und zu verbessern, und außerdem alle übrigen Teile, zum Beispiel Lüfter, Kugellager usw., die auf der Welle befestigt werden, ebenfalls durch Kleben mit der Welle zu verbinden. Dabei soll ohne Schleitbearbeitung ein genauer Paßsitz erreicht werden. Erfindungsgemäß wird dies dadurch erreicht1 daß die Welle im ungeschliffenen Zustand mit einer Erhebungen bildenden Aufrauhung versehen ist und der Kleber derart in den Vertiefungen der Aufrauhung gen angeordnet wird, daß er diese ausfüllt. Ferner werden die Erhöhungen der Aufrauhungen vor AuSbringung der zu befestigenden Teile kalibriert, um einen genauen Paßsitz zu erreichen.To achieve a good fit of the rotor core on the shaft it is known to arrange an adhesive between the shaft and the laminated core. The invention The underlying task is to connect the laminated core with the rotor shaft to simplify and improve with glue, and also all other parts, for example fans, ball bearings, etc., which are attached to the shaft, also to be connected to the shaft by gluing. In doing so, a precise fit can be achieved. According to the invention this is achieved in that provide the shaft in the unpolished state with a roughening that forms elevations and the adhesive is so in the depressions of the roughening gene is ordered that he fills this out. Furthermore, the ridges of the roughness calibrated prior to application of the parts to be fastened to ensure a precise fit to reach.
Durch die erfindungsgemäße Ausbildung der Welle wird erreicht, daß das Blechpaket und die zu befestigenden Teile mit festes Sitz unmittelbar auf der Läuferwelle betestigt werden und dabei die Haftung des Klebers zwischen Läuferwelle und Blechpaket erhöht wird. Ferner wird der Traganteil, der sonst nur durch die Spitzen der Aufrauhungen gebildet würde, durch den als Füllstoff wirkenden Kleber wesentlich vergrößert, so daß ein am ganzen Wellenuifang selbst Unebenheiten des Lagerrings ausfüllender Sitz erreicht wird. Durch die Kalibrierung wird ein guter Paßsitz erreicht, so daß eine Schleifbearbeitung der Welle nicht rerforderlich ist. The inventive design of the shaft is achieved that the laminated core and the parts to be fastened with a tight fit directly on the Rotor shaft are attached and thereby the adhesion of the adhesive between the rotor shaft and laminated core is increased. Furthermore, the contact area, which is otherwise only due to the Tips of the roughening would be formed by the glue acting as a filler significantly enlarged, so that there are bumps in the whole wave surface Bearing ring filling seat is achieved. The calibration makes a good one A snug fit is achieved so that grinding of the shaft is not required.
Zweckmäßigerweise wird die Aufrauhung durch eine Riffelung oder Kordelung bewirkt, die entweder an der gesamten Wellenoberfläche oder nur an den die Teile tragenden Stellen angeordnet werden kann. The roughening is expediently carried out by corrugation or cord causes that either on the entire shaft surface or only on the parts load-bearing bodies can be arranged.
Weitere vorteilhafte Einzelheiten der Erfindung sind in der nachfolgenden Beschreibung der beiliegenden Zeichnung eines Ausführungsbeispiels dargelegt. Further advantageous details of the invention are set out below Description of the accompanying drawings of an embodiment set forth.
In der Zeichnung ist mit 1 die Welle des Läufers bezeichnet, auf der das Blechpaket 2 sowie die Kugellager 3, der Kollektor 4 sowie Gebläselaufräder 5 angeordnet sind. Gemäß der Erfindung ist die Läuferwelle an den die genannten Teile tragenden Stellen mit einer Aufrauhung 6 versehen, die aus einer Längariffelung besteht. Anstelle der Längsriffelung kann die Welle auch durch eine Kordelung aufgerauht werden. Um einen zentrischen Sitz der auf der Welle zu befestigenden Teile zu erhalten, wird die Welle nach der Aufrauhung kalibriert, so daß die Erhebungen gleichen Durchmesser erhalten. Für die Verbindung des Blechpaketes 2 und der übrigen Teile 3 bis 5 mit der Welle wird auf der Aufrauhung ein Kleber bzw. aushärtender Füllstoff 7, der zwischen die Vertiefungen der Aufrauhungen 6 eingebracht wird, aufgetragen. Der Kleber füllt den Zwischenraum zwischen den kalibrierten Spitzen der Aufrauhung und dem Grund der Welle aus. Nach dem Aufbringen der zu befestigenden Teile (Blechpaket, Kugellager usw..) bildet der Kleber eine Verbindung zwischen Wellenumfang und den Paßflächen der zu befestigenden Teile, wobei am ganzen Wellenumfang selbst Unebenheiten der Lagersitze ausgeglichen werden. In the drawing, 1 denotes the shaft of the rotor, on the laminated core 2 and the ball bearings 3, the collector 4 and fan impellers 5 are arranged. According to the invention, the rotor shaft is connected to the aforementioned Parts bearing Provided with a roughening 6, which from there is a longitudinal corrugation. Instead of the longitudinal corrugation, the shaft can also go through a cord can be roughened. To ensure a centric seat on the shaft fastened parts, the shaft is calibrated after roughening, so that the elevations have the same diameter. For connecting the laminated core 2 and the remaining parts 3 to 5 with the shaft an adhesive is applied to the roughening or hardening filler 7, which between the depressions of the roughening 6 is introduced, applied. The glue fills the space between the calibrated ones Peaks of the roughness and the bottom of the wave. After applying the to be fastened Parts (laminated core, ball bearings, etc.) the adhesive forms a connection between Shaft circumference and the mating surfaces of the parts to be fastened, with the entire shaft circumference even unevenness of the bearing seats can be compensated.
Nach dem Aushärten ergibt sich eine faste Verbindung sowie ein einwandfreier Paßsitz auf der Welle.After hardening, the connection is firm and flawless Snug fit on the shaft.
