Description
Die Erfindung betrifft ein Schaufelrad, insbesondere Lauf- oder Leitrad für hydrodynamische Kupplungen bzw. Getriebe, zusammengesetzt aus Außenschale, Schaufeln, und Kernringschale, und ein Verfahren zur Herstellung dieses Schaufelrades.The invention relates to a paddle wheel, in particular an impeller or stator for hydrodynamic couplings or gears, composed of outer shell, blades, and core ring shell, and a method for manufacturing this impeller.
Ziel der Erfindung ist ein Schaufelrad, das so zusammengebaut ist, daß die Einzelteile des Schaufelrades durch den Druck der umlaufenden Flüssigkeit nicht gelöst werden und eine sichere Verbindung und Verrieglung zwischen den Einzelteilen während des Betriebes gewährleistet ist, und dessen Einzelteile durch einen einfachen Arbeitsvorgang schnell zusammengebaut werden können.The aim of the invention is a paddle wheel which is assembled so that the individual parts of the paddle wheel by the pressure of the circulating liquid cannot be released and a secure connection and locking between the individual parts is guaranteed during operation, and its individual parts by a simple Operation can be assembled quickly.
Zur Erreichung dieses Ziels sind bei dem erfinderischen Schaufelrad mindestens eine formschlüssige Verbindungsstelle und eine andere Verbindungsstelle vorhanden, die in der einen Richtung formschlüssig und in der anderen Richtung reibungsschlüssig wirkt. Weitere Einzelheiten des erfinderischen Schaufelrades sowie ein Verfahren zu seiner Herstellung werden nachstehend an Hand der Zeichnung erläutert.To achieve this goal, the inventive paddle wheel at least one form-fitting connection point and one other connection point present, which form-fit in one direction and friction-fit in the other direction works. Further details of the inventive paddle wheel and a method its production are explained below with reference to the drawing.
Die Zeichnung zeigt im Ausschnitt eine Seiten= ansieht eines Schaufelrades einer Föttinger-Kupplung. Die Außenschale 11 trägt Schaufeln 18 aus federndem Blech, die mit Laschen 38 durch Schlitze der Kernringschale 22 greifen. Die Laschen 38 sind gegen die innere Fläche der Kernringschale 22 umgebogen, so daß an dieser Stelle eine feste formschlüssige Verbindung besteht.The drawing shows a section of a side = looking at a paddle wheel a Föttinger coupling. The outer shell 11 carries blades 18 made of resilient sheet metal, which engage with tabs 38 through slots in the core ring shell 22. The tabs 38 are bent against the inner surface of the core ring shell 22, so that at this point there is a firm, form-fitting connection.
Am äußeren Rand besitzt die Kernringschale Einkerbungen 41, die nach rechts in die Oberfläche der Kernringschale auslaufen und nach links eine zur Oberfläche etwa rechtwinklige Schulter 40 haben, gegen die sich die Schaufeln federnd anlehnen. Die Schaufeln sind also nach einer Seite formschlüssig, nach der anderen reibungsschlüssig in .den Kerben 41 gehalten. Die Kernringschale selbst ist aus federndem Blech hergstellt und ist unter leichter. Spannung in den Schaufelkranz eingesetzt.At the outer edge, the core ring shell has notches 41, which after to the right into the surface of the core ring shell and to the left one to the surface have approximately right-angled shoulder 40 against which the blades lean resiliently. The blades are therefore form-locking on one side and friction-locked on the other held in the notches 41. The core ring shell itself is made from resilient sheet metal and is under lighter. Tension used in the blade ring.
Das Schaufelrad wird in der Weise hergestellt, daß die Außenschale mit den darin befestigten Schaufeln in einen Halter eingebaut wird, die Kernringschale konzentrisch zur Achse der Außenschale aufgestellt und auf letztere unter leichter Zusammenpressung zu bewegt wird, um die Verbindungsmittel ineinandergreifen zu lassen. Dann läßt man die Kernringschale sich unter der Wirkung ihrer Vorspannung ausdehnen, so daß die Vorsprünge der Schaufeln in die Kerben 41 der Kernringschale einrasten.The paddle wheel is manufactured in such a way that the outer shell is installed in a holder with the blades attached, the core ring shell set up concentrically to the axis of the outer shell and on the latter under lighter Compression is moved to to interlock the connecting means. Then the core ring shell is allowed to expand under the effect of its prestress, so that the projections of the blades snap into the notches 41 of the core ring shell.
