Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der Apparat dient dem Zwecke, die Winkelgeschwindigkeit eines rotirenden Maschinentheiles, z. B. einer Welle, einer Trommel oder dergl., d. h. die Umdrehungen, die derselbe bei gleichbleibender Geschwindigkeit innerhalb einer gewissen Zeit (Secunde, Minute, Stunde) machen würde, dem Auge jederzeit anzuzeigen und diese Angaben, wenn erwünscht, nach einer beliebigen Stelle zu übertragen.The purpose of the apparatus is to measure the angular velocity of a rotating machine part, z. B. a shaft, a drum or the like., D. H. the turns that the same at constant speed within a certain time (seconds, minutes, hours) would make to indicate to the eye at any time and this information, if desired, after to be transmitted anywhere.
Er besteht aus dem eigentlichen Geschwindigkeitsmesser, dem Anzeigeapparat mit Scala und, wenn letzterer nicht direct mit ersterem verbunden wird, der Leitung.It consists of the actual speedometer, the display device with a scale and, if the latter is not connected directly to the former, the line.
Der Gegenstand der Erfindung bietet im Gegensatz zu anderen Geschwindigkeitsmessern, welche ebenfalls durch Vermittelung von unter der Einwirkung der Centrifugälkraft stehenden Flüssigkeiten verschiedenartige Pressungen eines eingeschlossenen Luftquantums hervorrufen, den Vortheil, dafs die sonst unvermeidlichen Stopfbüchsen oder ähnliche Dichtungen vollständig wegfallen dadurch, dafs die zu pressende Luftmenge erst indirect unter dem Einflufs der Centrifugälkraft steht.The object of the invention, in contrast to other speedometers, which are also under the influence of the centrifugal force Liquids cause various pressures of an enclosed quantum of air, the The advantage is that the otherwise unavoidable stuffing boxes or similar seals are complete disappear because the amount of air to be pressed is only indirectly under the influence of the Centrifugal force is.
Zu dem Zwecke ist innerhalb des centralen Gefäfses α (Fig. 1) des mit Flüssigkeit, hauptsächlich Quecksilber, gefüllten rotirenden Systems cpmmunicirender Gefäfse ab g ein oben geschlossenes, gegen α ungedichtetes Rohr s unbeweglich und freistehend angeordnet. In der Ruhe ist der Quecksilberstand in allen Gefäfsen a, s und g gleich hoch. Durch den Einflufs der Bewegung wird das Quecksilber nach den Gefäfsen g getrieben und damit ein Sinken der Quecksilbersäule hervorgerufen. Hierdurch entsteht in dem über der Quecksilbersäule liegenden Raum eine Druckverminderung, deren Gröfse von der Rotationsgeschwindigkeit abhängt. For the purpose is within the central Gefäfses α (Fig. 1) with fluid, mainly mercury, filled revolving system cpmmunicirender from Gefäfse g closed at the top, arranged an immobile and detached against α ungedichtetes pipe s. At rest the level of mercury in all vessels a, s and g is the same. The influence of the movement drives the mercury towards the vessels g , thus causing the mercury column to sink. This creates a pressure reduction in the space above the mercury column, the magnitude of which depends on the speed of rotation.
Diese Druckverminderung wird auf einen zur Anzeige des Luftdruckes geeigneten Apparat (Manometer m, Barometer i oder dergl., Fig. 3, 4 und 5) entweder direct oder durch Vermittelung einer zwischengeschalteten dünnen Rohrleitung r übertragen.This pressure reduction is transmitted to an apparatus suitable for displaying the air pressure (manometer m, barometer i or the like, FIGS. 3, 4 and 5) either directly or through the intermediary of a thin pipe r connected in between.
Ein Hahn, Ventil oder dergl. \ gestattet im Ruhezustande einen Ausgleich zwischen der atmosphärischen Luft und dem Inneren des Rohres bezw. Anzeigeapparates.A cock, valve or the like. \ Allows a balance between the atmospheric air and the interior of the pipe or the like. Display apparatus.
