Die Stromturbine ist eine Axialturbine mit horizontaler Welle, welche derart zwischen zwei in einem Strom verankerte oder an das Ufer geheftete Schwimmkörper eingebaut ist, dafs eine theilweise Beaufschlagung vorhanden ist. Dabei wird constante Geschwindigkeit in der Weise erzielt, dafs die Schaufeln des Laufrades im äufseren und inneren Radkranz gelagerte Drehzapfen besitzen, wobei die im inneren Radkranz gelagerten Zapfen Kurbeln tragen, welche mit einer durch einen Centrifugalregulator auf der Welle zu verschiebenden Hülse verbunden sind.The power turbine is an axial turbine with a horizontal shaft, which is so between two floats anchored in a stream or attached to the bank are installed, that there is a partial loading. Constant speed is used in the way that the blades of the impeller are supported in the outer and inner wheel rim Have trunnions, the journals mounted in the inner wheel rim carry cranks which are connected to a centrifugal regulator are connected to the shaft to be displaced sleeve.

In beiliegender Zeichnung ist Fig. ι ein Längenschnitt der Turbine, Fig. ι eine Vorderansicht eines Theiles des Laufrades und Fig. 3 eine Vorderansicht des ganzen Motors, während Fig. 4 die wechselseitige Stellung der Leitschaufeln und Laufradschaufeln auf der entwickelten Mantelfläche des äufseren Radkranzes darstellt; Fig. 5 und 6 zeigen zwei Varianten der Constructionsweise der Radkränze, und Fig. 7 läfst die am besten geeignete Transmissionsweise erkennen.In the accompanying drawing, FIG. 1 is a longitudinal section of the turbine, FIG. 1 is a front view of part of the impeller and FIG. 3 is a front view of the entire motor, while FIG ; FIGS. 5 and 6 show two variants of the manner of construction of the wheel rims, and FIG. 7 shows the most suitable mode of transmission.

Die beiden Schwimmkörper α sind durch Quertheile b verbunden, an welchen die Lager für die Welle, c angebracht sind. An Langschwellen d, welche auf den vorderen Traversen ruhen, ist der ä'ufsere Mantel e des Leitapparates E angebracht, während der innere ringförmige Mantel e, durch die schraubenförmigen Leitschaufeln e₂ in seiner Stellung gehalten wird. Der sich trichterförmig erweiternde Vorderrand des äufseren Leitschaufelmantels e einerseits und der mit dem inneren Leitschaufelmantel O₁ verbundene, die Welle c concentrisch umschliefsende ogivale Blechkörper f andererseits bewirken einen gleichmäfsigen, stofsfreien Wassereinlauf.The two floating bodies α are connected by transverse parts b , to which the bearings for the shaft, c are attached. The outer casing e of the guide apparatus E is attached to long sleepers d, which rest on the front cross members, while the inner annular casing e is held in its position _{by the helical guide vanes e 2.} The funnel-shaped widening front edge of the outer guide vane jacket e on the one hand and the ogival sheet metal body f , which is connected _{to the inner guide vane jacket O 1} and encloses the shaft c concentrically, on the other hand, cause a uniform, substance-free water inlet.

Der innere Radkranz ^₁ des Laufrades G ist mit dem äufseren Radkranz g durch mehrere radial gestellte Blechwände g₃ verbunden und sitzt seinerseits an einer Blechscheibe g _A, welche mittelst Schraubenbolzen an die Nabe g_h geschraubt und durch den Blechkonus g₆ allseitig verstrebt ist.The inner wheel rim ^ _{1 of} the impeller G is connected to the outer wheel rim g by several radially positioned sheet metal walls g ₃ and in turn sits on a sheet metal disk g _A , which is screwed to the hub g _h by means of screw bolts and braced on all sides by the sheet metal cone g _6.

Die zwischen den äufseren Radkranz g und den inneren Radkranz g_l des Laufrades eingelagerten schraubenförmigen Schaufeln g₂ besitzen am äufseren Ende einfache Drehzapfen g₇ und am inneren Ende Drehzapfen g_& mit Kurbeln g₉ sammt Kurbelzapfen g₁₀. Die Kurbelzapfen g_l0 reichen lose in Oeffnungen einer auf Welle c sitzenden Blechtrommel /;, welche mit dieser Welle rotirt und längs derselben durch einen Arm des Winkelhebels j verschoben werden kann; der andere Arm dieses Hebels j ist mit der Hülse eines von der Welle c aus angetriebenen Konuspendel-Regulators k verbunden. Wie aus der Zeichnung ersichtlich, sind die Oeffnungen, in welche die Kurbelzapfen g_l0 hineinreichen, in der Weise hergestellt, dafs mit der Blechtrommel h ein Ring h j durch Stehbolzen verbunden ist. Ebenso ist ersichtlich, dafs diese Trommel h an einer Hülse h₂ sitzt, welche zur Verminderung der Reibung durch Frictionsrollen auf der Welle c geführt ist.The helical blades g ₂ embedded between the outer wheel rim g and the inner wheel rim g _{l of} the impeller have simple pivot pins g ₇ at the outer end and pivot pins g _& with cranks g ₉ together with crank pins _{g 10} at the inner end . The crank pins g ₁₀ extend loosely into openings of a sheet metal drum /; which is seated on shaft c and which rotates with this shaft and can be displaced along it by an arm of the angle lever j; the other arm of this lever j is connected to the sleeve of a conical pendulum regulator k driven by the shaft c . As can be seen from the drawing, the openings into which the crank pins g _{l0 extend} are made in such a way that a ring h j is connected to the sheet metal drum h by stud bolts. It can also be seen that this drum h is seated on a sleeve h ₂ , which is guided on the shaft c by friction rollers to reduce the friction.

Um diese Regelung empfindlicher zu machen, geht, wie Fig. 2 zeigt, die durch die Zapfen Si Si gebildete Drehachse nicht durch den Mittelpunkt der Schaufelfläche, sondern theiltIn order to make this regulation more sensitive, as FIG. 2 shows, the axis of rotation formed by the pins Si Si does not pass through the center of the blade surface, but rather divides it

Claims

the same into two unequal halves in such a way that the water pressure, which is unevenly distributed on both sides of the axis of rotation, constantly tends to turn the shovel and thereby move the drum / 2 backwards. In the normal position of the blades, this effort is compensated for by loading the upper arm of the angle lever j by means of a displaceable weight J _1; but as soon as there is a disturbance of the necessary relation between water pressure and resistance, this disturbance will be applied to the two unequal parts of the vane to an unequal degree, and in this way a regulating adjustment of the vanes will take place.

The _{thrust bearing C 1} at the rear end of the shaft c is adjustable so that the impeller can always be positioned precisely against the guide vane apparatus.

The transmission of the movement from this motor to the work machine to be operated by it can take place in the manner shown in FIG. 1 or in the manner shown in FIG. In the first case, the countershaft m _{carrying a pulley Wi 1 is} driven by a spur gear transmission, while in the second case the countershaft is set in rotation directly from the impeller of the turbine by a chain transmission.

PATENT REQUIREMENTS:
