Abstract
Description
Trommel für Wäschebehandlungsmaschinen und Verfahren zur Herstellung der Trommel Die Erfin4ung. betrifft eine Trommel für Wäschebehandlungsmaschinen, an deren Stirnseiten Flansche befestigt sind, die Mitnehmer zur Trommellagerung und zum Trommelantrieb tragen, sowie ein Verfahren zur Herstellung der Trommel.Laundry machine drum and method of manufacture of the drum The invention. relates to a drum for laundry machines, Flanges are attached to the end faces, the drivers for drum mounting and carry to the drum drive, as well as a method for manufacturing the drum.
Bei ,en bekannten Trommel-n für Wäschebehandlungsmaschinen sind an den Trommelstirnseiten Flansche angeschraubt, angenietet oder angeschweißt. Diese Flansche tragen äe einen Mitnehmer in Form eines Wellenstumpfes, wobei die Befestigung des Mitnehmers am Flansch durch Verschweißen erfolgt (DD-OS 1 936 380).At, s known drum-s for laundry treatment machines are on Flanges screwed, riveted or welded to the front of the drum. These Flanges wear a driver in the form of a stub shaft, with the Attachment the driver on the flange is done by welding (DD-OS 1 936 380).
Da die Mitnehmer insbesondere im Schleuderbetrieb bei hoher Drehzahl sehr großen dynamischen Belastungen ausgesetzt sin werden bei der Fertigung der Trommel an die Verbindung zwischen den Mitnehmern und den Flanschen erhebliche Anforderungen gestellt, die teilweise einen hohen Wertigungsausschuß bedingen. Andererseits kann ein erheblicher Schaden an der Maschine entstehen, falls die S-chweißverbindung zwischen den Mitnehmern und der Trommel während des Betriebes der Maschine bricht.Because the driver especially in the spin mode at high speed are exposed to very high dynamic loads during the manufacture of the Drum on the connection between the drivers and the flanges make considerable demands which sometimes require a high evaluation committee. On the other hand, can Significant damage to the machine will occur if the welded joint breaks between the drivers and the drum during operation of the machine.
Aufgabe der Erfindung ist es, eine Trommel für Wäschebehandlungsmaschinen zu schaffen, die sich durch eine einfache und sichere Verbindung zwischen den Mitnehmern und den Trommelstirnseiten auszeichnet.The object of the invention is to provide a drum for laundry treatment machines to create a simple and secure connection between the drivers and the front sides of the drum.
Erfindungsgemäß wird diese Aufgabe dadurch gelost, daß die Mitnehmer in kraftflüssiger Verbindung in die Flansche eingelassen sind.According to the invention this object is achieved in that the driver are embedded in the flanges in a fluid connection.
In vorteilhafter Ausführung weisen die Mitnehmer Klauen auf und die Klauen sind in die Flansche eingestanzt.In an advantageous embodiment, the drivers have claws and Claws are stamped into the flanges.
Die erfindungsgemäße Trommel ermöglicht ferner eine besonders einfache Fertigung, wenn die Klauen der Mitnehmer ohne Vorlochung der Flansche in diese eingestanzt werden.The drum according to the invention also enables a particularly simple one Production when the claws of the drivers are punched into the flanges without pre-punching them will.
Dabei kann die Verbindung zwischen den Flanschen und den Mitnehmern noch dadurch weiter verbessert werden, daß die die Flansche durchdringenden Elanenenden nach dem Einstanzen gestaucht werden.The connection between the flanges and the drivers can be further improved in that which penetrate the flanges Elanenends are compressed after punching.
In der Zeichnung ist eine erfindungsgemäße Verbindung zwischen einer Trommelstirnseite, einem Flansch und einem Mitnehmer teilweise im Schnitt dargestellt.In the drawing is a connection according to the invention between a Drum face, a flange and a driver partially shown in section.
Der zur lagerung einer Trommel einer Wäschebehandlungsmaschine dienende Mitnehmer 1 weist Klauen 3 auf, die in einen Flansch 2 eingestanzt sind. Der Flansch 2 ist bot spielsweise über NietverTindungen 4 an der Trommelstirnseite 5 befestigbar.The one used to store a drum of a laundry treatment machine Driver 1 has claws 3 which are punched into a flange 2. The flange 2 can be fastened to the front side of the drum 5 via rivet connections 4, for example.
Da die Stanzverbindung zwischen den Klauen 3 und dem Flansch 2 ohne Vorlochung des Flansches erfolgt, erübrigt sich ein Stannwerkzeug für eine Vorlochung und es ergibt sich eine krafddlüssige Verbindung mit vollständiger Materialanlage zwischen den Klauen und dem Flansch.Since the punched connection between the claws 3 and the flange 2 without The flange is pre-punched, so there is no need for a stamping tool for pre-punching and there is a forceful connection with a complete material system between the claws and the flange.
Damit ist ein einwandfreie Übertragung des Drehmoments möglich und es ist ebenso ein lockern der Verbindung im Reversierbetrieb der Trommel nahezu ausgeschlossen.A perfect transmission of the torque is thus possible and there is also almost a loosening of the connection in the reversing operation of the drum locked out.
Eine weitere Verstärkung der Verbindung zwischen dem Mitnehmer und dem Flansch ist durch Stauchen der den Flansch durchdringenden Klauenenden 6 möglich. SchlieB-lich wird durch die den Flansch 2 durchdringenden Klauenenden 6 selbst dann eine Halterung der Trommel zwischen den in sieht Fargestelltet lagern angeordneten Mitnehmern erzielt, ween die Verbindung zwischen den Flanschen und den Mitnehmerm ausgöschlagen würde.A further strengthening of the connection between the driver and the flange is possible by upsetting the claw ends 6 penetrating the flange. Finally, through the claw ends 6 penetrating the flange 2, even then a holder of the drum between the bearings in Fargestellet sees arranged Achieved drivers, ween the connection between the flanges and the Mitnehmerm would turn out.
