Abstract

The invention relates to a flywheel with four moving mass parts (1). Said mass parts move under the effect of the centrifugal force between a position at a minimum distance and a position at a maximum distance from the rotational axis (2), so that the mass inertia of the centrifugal mass also varies between a minimum and maximum value. In the case of known centrifugal masses, such as the axially displaceable revolving disk flywheel (5), the mass inertia is constant and determines the size of the necessary driving torque. The inventive flywheel only has to overcome a reduced mass inertia during starting or increasing speed which has previously decreased, so that a reduced driving torque is required. This results in a greater storage capacity at a given driving torque. The method and the flywheel can be applied especially to electric drives, especially with a battery or solar generator.

Description

VERFAHREN UND EINRICHTUNG ZUR SPEICHERUNG ENERGIE IN EINER SCHWUNGMASSEMETHOD AND DEVICE FOR STORING ENERGY IN A FLYING MASS
Die bekannten Gyro- und anderen Schwungantriebe besitzen ein konstantes Massenträgheitsmoment. Dies wirkt sich insofern ungünstig aus, als sowohl beim Anfahren wie auch beim Erhöhen von durch Leistungsabgabe reduzierten Drehzahlen ein relativ hohes, vom Trägheitsmoment des Schwungrades abhängiges Antriebsmoment erforderlich ist.The known gyro and other flywheel drives have a constant moment of inertia. This has an unfavorable effect insofar as a relatively high drive torque, which is dependent on the moment of inertia of the flywheel, is required both when starting off and when increasing speeds that are reduced by power output.
Das Ziel der Erfindung besteht darin, diese durch konstantes Trägheitsmoment der Schwungmasse bedingten Nachteile zu beheben. Dies wird erfindungsgemäss durch das Verfahren mit den Merkmalen des Patentanspruches 1 und durch die Einrichtung mit den Merkmalen des Patentanspruches 3 erreicht.The aim of the invention is to eliminate these disadvantages caused by the constant moment of inertia of the flywheel. This is achieved according to the invention by the method with the features of claim 1 and by the device with the features of claim 3.
Im Ruhezustand und vorzugsweise auch bei kleineren Drehzahlen verharren die beweglichen Masseteile zunächst in Zentrumsnähe. Da das Trägheitsmoment noch klien ist, genügt ein kleineres Antriebsmoment. Mit zunehmender Drehzahl und zunehmender Zentrifugalkraft werden die beweglichen Masseteile nach aussen bewegt, sodass sich nun ein maximales Trägheitsmoment mit entsprechend erhöhter Energiespeicherung Kapazität der Schwungmasse einstellt. Bei Belastung verringert sich anderseits die Auslenkung der Masseteile mit reduzierter Drehzahl, sodass sich auch das Trägheitsmoment reduziert, weshalb wiederum zur Erhöhung der Drehzahl ein geringeres Antriebsmoment ausreicht, als bei konstantem maximalem Trägheitsmoment von Nöten wäre.In the idle state and preferably also at lower speeds, the movable mass parts initially remain near the center. Since the moment of inertia is still small, a smaller drive torque is sufficient. With increasing speed and increasing centrifugal force, the movable mass parts are moved outwards, so that a maximum moment of inertia with a correspondingly increased energy storage capacity of the flywheel mass is established. On the other hand, under load, the deflection of the mass parts decreases with a reduced speed, so that the moment of inertia is also reduced, which in turn means that a lower drive torque is sufficient to increase the speed than would be necessary with a constant maximum moment of inertia.
Das erfindungsgemässe Verfahren wird unter Bezugnahme auf das in der Zeichnung dargestellte Ausführungsbeispiel der erfindungs- gemässen Einrichtung in folgendem beispielsweise erläutert und zwar zeigt:The method according to the invention is explained with reference to the embodiment of the device according to the invention shown in the drawing, for example in the following and shows:
Fig.l Schwungrad im Querschnitt und Grundriss im Stillstand, Masseteile sind ins Zentrum gerichtet.Fig.l flywheel in cross section and floor plan at a standstill, mass parts are directed towards the center.
Fig.2 Schwungrad im Querschnitt und Grundriss in Drehbewegung, Masseteile vergrössern den Trägheitsdurchmesser infolge Zentrifugalkraft, durch Ausschwenken. Die Masseteile 1 werden durch Ferderdruck und Eigengewicht der mitlaufenden Schwungscheibe über die Hubstangen im Stillstand und bei kleiner Drehzahl im Zentrum gehalten, dadurch ist der kleine Trägheitsdurchmesser gegeben. Wird nun das in Fig. 1 dargestellte Schwungrad in Drehbewegung gebracht, so werden die Masseteile 1 infolge der Zentrifugalkraft nach aussen gezogen wie dies Fig.2 zeigt. Durch das Ausschwenken der Masseteile 1 wird der Trägheitsdurchmesser vergrössert und der Radumfang der Masseteile erstellt, was gleichzeitig eine Vergrösserung des Trägheitsmomentes bewirkt. Die gesamte Schwungmasse wird mit zwei Lagern 7 montiert, wobei das untere zusätzlich mit einem Axiallager vers- hen ist.Fig. 2 Flywheel in cross section and floor plan in rotary motion, mass parts enlarge the inertia diameter due to centrifugal force, by swinging out. The mass parts 1 are held at standstill and at a low speed in the center by the pressure and weight of the moving flywheel via the lifting rods, which gives the small inertia diameter. If the flywheel shown in FIG. 1 is now rotated, the mass parts 1 are pulled outwards as a result of the centrifugal force, as shown in FIG. By swiveling out the mass parts 1, the inertia diameter is increased and the wheel circumference of the mass parts is created, which at the same time causes an increase in the moment of inertia. The entire flywheel mass is mounted with two bearings 7, the lower one being additionally provided with an axial bearing.
Die markantesten Unterschiede zwischen dem herkömmlichen bekannten Schwungrad sind; das herkömmliche Schwungrad hat eine starre Schwungmasse und einen gleichbleibenden Trägheitsdurchmesser; demgegenüber besitzt das erfindungsgemässe beschriebene Schwungrad eine variable Schwungmasse und ein in sich selbst veränderlichen Kreisbahndurchmesser. Dies hat den Vorteil, dass das Trägheitsmoment vergrössert respektiv verkleinert werden kann, indem der Kreisbahndurchmesser verkleinert und bei Erreichen der optimalen Drehzahl sich der Kreisbahndurchmesser wieder bis auf das Maximum erweitert.The most striking differences between the conventional known flywheel are; the conventional flywheel has a rigid flywheel mass and a constant inertia diameter; In contrast, the flywheel described according to the invention has a variable flywheel mass and an orbital diameter that can change in itself. This has the advantage that the moment of inertia can be increased or decreased, respectively, by reducing the orbit diameter and, when the optimum speed is reached, the orbit diameter expands again to the maximum.
Bei Gebrauch der beschriebenen Einrichtung, erziehlt man folgende Vorteile:When using the described device, the following advantages are achieved:
Mit einer kleinen Antriebskraft ( Elektromotor oder andere Antriebsquelle ) kann über die Achse eine vorerst kleine Schwungmasse mit kleinem Radumfang Fig. 1 in Drehbewegung gebracht werden, wobei nur ein kleines Trägheitsmoment auftritt. Sobald durch die Drehbewegung die Masseteile 1 infolge der Zentrifugalkraft ausgefahren sind, hat sich auch der Trägheitsdurchmesser vergrössert und der Radumfang Fig.2 ist erstellt, wobei sich gleichzeitig auch das Trägheitsmoment vergrössert hat. Solange die Schwungmasse sich im Solldrehzahlbereich hält, kann die Antriebskraft klein gehalten werden. Bei Drehzahlabfall verkleinert sich der Trägheitsdurchmesser automatisch und der Antrieb bringt die verkleinerte Schwungmasse wieder auf die Solldrehzahl, ohne dass ein Unterbruch oder Stillstand eintritt. Diese Trägheitsdurchmesservariabilität bringt naturgemäss recht be- trächtliche Zentrifugalkraft, welche sich in kinetischer Energie in der Schwungmasse speichert.With a small driving force (electric motor or other drive source), a initially small flywheel with a small wheel circumference Fig. 1 can be rotated about the axis, whereby only a small moment of inertia occurs. As soon as the mass parts 1 are extended as a result of the centrifugal force due to the rotary movement, the inertia diameter has also increased and the wheel circumference has been created, FIG. 2, the moment of inertia also increasing at the same time. As long as the flywheel remains in the target speed range, the driving force can be kept small. If the speed drops, the inertia diameter automatically decreases and the drive brings the reduced flywheel mass back to the target speed without an interruption or standstill. This variability in inertia diameter naturally brings quite pregnant centrifugal force, which is stored in kinetic energy in the flywheel.
Mit der beschriebenen Einrichtung kann infolge Energiespeicher- ung eine verlängerte Energie- Abnahme erziehl werden. Diese verlängerte Energie- Abnahme wirkt sich besonders günstig bei einer elektrischen Antriebskraft aus, insbesondere, wenn der Antriebsmotor durch eine Batterie oder einen Solargenerator gespie- senwird.With the device described, an extended energy consumption can be achieved as a result of energy storage. This prolonged decrease in energy has a particularly favorable effect on an electric driving force, in particular if the drive motor is powered by a battery or a solar generator.
Durch den variablen Trägheitsdurchmesser wird sowohl das Trägheitsmoment als auch die Zentrifugalkraft recht erheblich verändert.Due to the variable inertia diameter, both the moment of inertia and the centrifugal force are changed quite considerably.
Die Erhöhung der Speicherung von kinetischer Energie bringt einen besseren Wirkungsgrad als üblich bei und zwar insofern, dass durch die Speicherung von kinetischer Energie eine längere Nutzungsdauer der Antriebskraft möglich wird. Increasing the storage of kinetic energy brings a better efficiency than usual in that the storage of kinetic energy enables a longer useful life of the driving force.
