Description

Bei Maschinen mit umlaufenden Polen, bei denen die Pole durch. Fliehkräfte hoch beansprucht sind, macht die sichere 'und zugleich einfache Befestigung der Pole an deren Tragkörper große Schwierigkeiten. Man hat zwar schon versucht, diese Schwierigkeiten dadurch zu beheben, daß man die Pole in der Längsrichtung !unterteilt hat und zwischen den einzelnen Tiefen Platten 'eingefügt hat, die , 10 durch den Polkranz hindurchgeführt sind tind durch deren aus dem Polkranz herausragende Teile Befestigungskeile getrieben sind. Man hat auch die Polschenkel lamelliert ausgeführt und Gruppen von Lamellen durch den PoI-kranz hindurchragen lassen und diesie Pole wie in dem vorerwähnten Fall durch Kepie an dem Polkrariz befestigt. Diese Befestigungsarten sind aber nur für Porräder mit großem Durchmesser brauchbar. Bei PoI-rädern mit kleinem Durchmesser, "wie er für hohe Geschwindigkeiten erforderlich ist, können sie nicht verwendet werden. Für solche Polräder wird durch die Erfindung eine vorteilhafte Befestigung dadurch gegeben, daßFor machines with rotating poles, where the poles go through. Highly stressed centrifugal forces are, makes the secure 'and at the same time simple attachment of the poles to their support body great difficulties. One has I have tried to solve these difficulties by keeping the poles in the Has divided longitudinal direction! And inserted plates' between the individual depths, the , 10 are passed through the pole rim through which parts protruding from the pole ring fastening wedges are driven. Man has also made the pole legs laminated and groups of lamellas through the poly wreath and let the poles protrude through Kepie, as in the above-mentioned case attached to the Polkrariz. These types of fastening are only available for Por wheels large diameter usable. For PoI wheels with a small diameter, "as he is for high speeds are required, they cannot be used. For such Pole wheels are given an advantageous attachment by the invention in that

Z5 die Polpaare, wie an sich bekannt, an ihrem inneren Ende kammartig ausgebildet werden. Weiterhin wird die Welle des Läufers verstärkt und an der Verstärkung mit senkrecht zur Laufachse verlaufenden Rillen versehen. In die Rillen werden die Polschenkel mit Zähnen eingesetzt und durch die Wellenverstärkung und die Zähne Biefestiigungsmittel hindurchgeführt.Z5 the pole pairs, as is known per se, on theirs inner end are formed like a comb. Furthermore, the shaft of the rotor is reinforced and provided on the reinforcement with grooves running perpendicular to the barrel axis. The pole legs with teeth are inserted into the grooves and through the shaft reinforcement and teeth fasteners passed therethrough.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung veranschaulicht. Diese zeigt ein 'Polrad mit einer Welle w mit einer Verdicfcungj^ in die nach der Erfindung· Rillen rur%>r§>rn>r§ 'eingedreht sind. Ferner zeigt sie einen Pol p, der ans Blechschichten O1 bis O9 zusammengesetzt ist, von denen die Schichten bif b3, b5, δ7 und b9 einen inneren Durchmesser besitzen, der dem Innendurchmesser der Rillen entspricht, während die Bleche b2) ba, be und bs einen Durchmesser besitzen, der dem Außendurchmesser der 4-5 Verdickung ν entspricht. Der Pol bildet so an seinem inneren Ende einen Kamm mit Zähnen. zu Z3, Z5, ζΊ, Z9, die in die Rillen ru rz, /•5, r7,/"9 eingesetzt sind und durch Bolzen η mit der Verdickung ν fest verbunden sind. Durch diese Anordnung wird eine äußerst sichere und einfach herstellbare Polbefestigung erreicht. Anstatt aus Eirüzelblechen können die Polteile bt bis O9 auch aus Platten hergestellt -werden.An embodiment of the invention is illustrated in the drawing. This shows a 'pole wheel with a shaft w with a thickening j ^ into which, according to the invention, grooves r u r %> r §> r n> r § ' are screwed. It also shows a pole p, which is composed of sheet metal layers O 1 to O 9 , of which the layers b if b 3 , b 5 , δ 7 and b 9 have an inner diameter which corresponds to the inner diameter of the grooves, while the sheets b 2) b a , b e and b s have a diameter which corresponds to the outer diameter of the 4-5 thickening ν. The pole thus forms a comb with teeth at its inner end. z u Z 3 , Z 5 , ζ Ί , Z 9 , which are inserted into the grooves r u r z , / • 5, r 7 , / " 9 and are firmly connected to the thickening ν by bolts η. By this arrangement an extremely safe and simple to manufacture pole fixture is obtained. Instead of the pole pieces can Eirüzelblechen b t up O 9 -Be prepared from plates.
