Description
Wirbelstromgeschwindigkeitstnesser. Die Erfindung bezieht sich auf Wirbelstromgeschwindigkeitsmesser mit gehäuseartigem Eisenschluß, der sich mit dem ringförmigen Magneten dreht, und einem scheibcn-oder glockenförmigen Anker, der zwischen Magnet und Eisenschluß drehbar gelagert ist. Bei den bekannten Anordnungen dieser Art sitzt der ringförmige Magnet in einem nicht magnetischen Gehäuseteil, der oben mit einer Messingplatte versehen ist und gegenüber dem Spalt in dem Magneten einen besonderen Eisenschlußkörper trägt. D:e Messingplatte trägt dabei zugleich die Schnecke zum Antrieb des den Weg messenden Zählwerkes..Eddy current velocity tnesser. The invention relates to Eddy current speedometer with a housing-like iron connection that connects to the ring-shaped magnet rotates, and a disk- or bell-shaped armature, which is rotatably mounted between magnet and iron connection. In the known arrangements In this way, the ring-shaped magnet sits in a non-magnetic part of the housing, which is provided with a brass plate at the top and opposite the gap in the magnet carries a special iron body. The brass plate carries at the same time the worm to drive the counter that measures the path ..
Gemäß der Erfindung ist für den Eisenschluß des auf nicht magnetischer Grundplatte gelagerten Ringmagneten ein kappenartiger, die wirksamen Teile zugleich abdeckender Gefäßkörper benutzt, der mit seinem unteren Rand in die nicht magnetische Grundplatte eingreift und in der Mittelachse die zum Antrieb des Wegstreckenzählers dienende Schnecke eingepreßt trägt.According to the invention, the iron connection is on non-magnetic Base plate mounted ring magnet a cap-like, the effective parts at the same time covering vessel body is used, the lower edge of which into the non-magnetic Base plate engages and in the central axis that drives the odometer serving snail is pressed in.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel.The drawing illustrates an embodiment.
Abb. i zeigt einen Schnitt durch das Magnetsystem und Abb. 2 die als Eisensehluß dienende Blechkappe. In den Darstellungen ist a die Antriebswelle, die mit der Grundplatte b fest verbunden ist. Auf dieser Grundplatte ist der ringförmige Magnet c befestigt, der im Schnitt durch den Luftspalt dargestellt ist. Auf d--x Grundplatte b sitzt ge:nä3 der Erfindung eine Blechkappe d, die mit ausgestanzten und abgebogenen Zungen e auf der Grundplatte b befestigt ist. Abb. z zeigt diese Blechkappe im Schaubild. In der Mittellinie derselben ist die Schnecke f zum Antrieb des Wegzählwerkes festgepreßt. Auf der Zeigerwelle g ist innerhalb des Magnetsystems der Anker h befestigt, der entgegen der Wirkung der nicht dargestellten üblichen Gegenfeder drehbar ist.Fig. I shows a section through the magnet system and Fig. 2 the as Iron cap serving as a metal cap. In the illustrations, a is the drive shaft that is firmly connected to the base plate b. On this base plate is the ring-shaped Magnet c attached, which is shown in section through the air gap. On d - x Base plate b sits ge: Na3 of the invention a sheet metal cap d, which is punched out with and bent tongues e is attached to the base plate b. Fig.z shows this Sheet metal cap in the diagram. In the center line of the same is the worm f for the drive of the travel counter firmly pressed. On the pointer shaft g is within the magnet system the anchor h attached, counter to the action of the usual, not shown Counter spring is rotatable.
