Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Vorliegende Erfindung bezweckt die Vermeidung der Uebelstä'nde, welche der für Windmotoren meist gebräuchlichen Schwungkraft- (Centrifugal-) Regelung bei der Verwendung von in Gelenken umklappenden Flügeln anhaften.The present invention aims to avoid the nuisances which the for Wind motors usually use inertia (centrifugal) control cling to hinged wings.

Die Ausrückung der Flügelflächen aus dem Winde geschieht in folgender Weise: Eine am festen Flügelarm befindliche Schraubenfläche zwingt den beweglichen Flügel, sobald er infolge zunehmender Centrifugalkraft nach aul'sen zu fliehen bestrebt ist, durch Gleiten auf ihr zugleich eine Vierteldrehung um seine Längsachse auszuführen. Dadurch wendet der Flügel dem Winde jetzt seine scharfe Kante zu, während die volle Fläche der Umdrehungsrichturig zugekehrt wird und infolge des erzeugten starken Luftwiderstandes als Bremse wirkt.The wing surfaces are disengaged from the winch in the following way: One on Fixed wing arm located screw surface forces the movable wing as soon as he as a result increasing centrifugal force tends to flee to the outside by sliding on it at the same time to perform a quarter turn around its longitudinal axis. This turns the wing the wind now has its sharp edge, while the full surface of the rotation is correct is turned and acts as a brake as a result of the strong air resistance generated.

Vermittelst der Zugstangen ss, welche die einzelnen Flügel mit einer gemeinsamen, auf der Motorachse verschieblichen Rosette r verbinden , sind die Flügel unter einander zu gleichartiger Bewegung zwangläufig vereinigt, und während sie infolge ihres Centrifugalbestrebens vermöge der durch die Schraubenbahn erzwungenen Drehung die Rosette r ständig zurückzuschieben trachten, wirkt eine beliebige andere Kraft P (meist Gewichte, aber auch Federn oder Winddruck) mittelst geeigneter Uebertragungen auf die Rosette ständig in entgegengerichtetem 'Sinne.By means of the tie rods ss, which connect the individual wings with a common rosette r, which can be moved on the motor axis, the wings are inevitably united to one another in a similar movement, and while they are constantly pushing back the rosette r due to their centrifugal tendency due to the rotation forced by the screw path any other force P (mostly weights, but also springs or wind pressure) acts constantly in the opposite sense by means of suitable transfers to the rosette.

Claims (1)

Patent-Anspruch:Patent claim: Schwungkraft-Selbstregelung für Windräder, dadurch gekennzeichnet, dafs die Flügel bei zu schnellem Gang infolge ihrer eigenen Schwungkraft sich auf einer Schraubenfläche vom Mittelpunkt entfernen und sich dadurch schräg oder spitz in den Wind einstellen.Inertia self-regulation for wind turbines, characterized in that the blades at walking too fast as a result of their own momentum on a helical surface away from the center point and thereby adjust to the wind at an angle or pointy.
