Description

WirbeIstromgeschwindigkeitsmesser. Die Erfindung bezieht sich auf Wirbelstromgeschwindigkeitsmesser mit sich drehendem Magnetsystem, dran aus einem ringförmigen Magneten und einem kleinen, dem Luftspalt gegenüberliegenden Eisenschlußstück besteht, und bei dem der glucken- oder scheibenförmige Anker zwischen Magnet und Eisenschluß liegt. Das Neue besteht darin, daß als Kraftlinienschlußkörper - ein kleiner, im unmagnetischen Gehäuse verschraubbarer, stopfenartiger Körper verwendet wird.Eddy current speedometers. The invention relates to Eddy current speedometer with rotating magnet system, turn from one ring-shaped magnet and a small iron end piece opposite the air gap exists, and in which the bell-shaped or disc-shaped armature between the magnet and Iron connection lies. The new thing is that as a force line connecting body - a small, plug-like body that can be screwed into the non-magnetic housing will.

Die Zeichnung veranschaulicht in Abb. r d!ie Anordnung im Schaubild und in Abb. z im-Schnitt durch das Magnetsystem bei einer Anordnung mit scheibenförmigem Anker und in Abb. 3 bei einer Anordnung mit glockenförmigem Anker.The drawing illustrates in Fig. R the arrangement in the diagram and in Fig. z in section through the magnet system in an arrangement with a disk-shaped Anchor and in Fig. 3 for an arrangement with a bell-shaped anchor.

In Abb. i ist a der permanente ringförmige Magnet und b der Luftspalt desselben, während c den vefwendeten Kraftlinienschlußkörper darstellt. Zwischen diesem stopfenförmigen Kraftlinienschlußkörper c und dem permanenten Magneten a bewegt sich bei der Anordnung nach Abb. - der scheibenförmige Anker d. Dort ist der permanente Magnet a in dein unmagnetischen Gehäuse f in bekannter Weise gelagert, in das auch der stopfenartigeKraftlinienschlußkörperc eingeschraubt ist. h .ist die Zeigerwelle. Das Gehäuse f ist natürlich in irgendwelcher Weise zweiteilig zu machen, damit sowohl der scheibenförmige Anker d als auch der ringförmige Magnet ca eingebracht werden können.In Fig. I, a is the permanent ring-shaped magnet and b is the air gap of the same, while c represents the connecting body used. Between this plug-shaped power line connecting body c and the permanent magnet a moves in the arrangement according to Fig. - the disk-shaped armature d. There the permanent magnet a is mounted in the non-magnetic housing f in a known manner, into which the stopper-like force line connecting body c is also screwed. h . is the pointer shaft. The housing f is of course to be made in two parts in some way so that both the disk-shaped armature d and the ring-shaped magnet ca can be introduced.

Der stopfenförmige Kraftlinienschlußkörper c hat eine erhebliche Bedeutung für das Auswuchten des umlaufenden Magnetsystems. Da in ringförmigen Magneten infolge des radialen Spaltes eine gewisse Masse fehlt, sind Ausgleichsmassen anzubringen, die bei zweckentsprechender Bemessung des Kraftlirnienschlußkörpers überflüssig werden. Außerdem ist die Forderung, solche Kraftlinienschlußkörper zum Zwecke der Einstellung des Meßinstrumentes verstellbär zu machen, durch die Verschraubbarkeit erfüllt.The plug-shaped power line connecting body c is of considerable importance for balancing the rotating magnet system. Because in ring-shaped magnets as a result of the radial If the gap is missing a certain amount of mass, it is compensating masses to be attached, with the appropriate dimensioning of the power lined connecting body become superfluous. In addition, the requirement is such power line connecting body for To make the purpose of adjusting the measuring instrument adjustable by screwing Fulfills.

In Abb. 3 ist statt eines scheibenförmigen Ankers d ein glockenförmiger benutzt.In Fig. 3, instead of a disk-shaped anchor d, a bell-shaped one is used used.
