Abstract

The centrifugal clutch has automatic actuator connected to electrical circuit by a solenoid switch. The clutch is engaged only after the driving unit has reached certain speed. This ensures good starting characteristics when starting driven machines from stand still. This arrangement can be used also as a centrifugal brake. It protects machinery such as lifts against electrical power supply failure. The centrifugal clutch (3) is held on drive shaft (1). The centrifugal weights (5) are held concentrically on drum (9) in the driven machine. These weights are moved by solenoid (6) actuated levers (4) and expanding elements (7). The automatic clutch operating mechanism has spring (10) on the machine shaft (8).

Description

Beschreibung: Fliehkraftkupplung mit automatischer Schalt-Description: Centrifugal clutch with automatic shift

einrichtung Die-vorliegende Erfindung betrifft eine schaltbare Fliehkraftkupplung, bei welcher Fliehgewichte auf einer umlaufenden Antriebswelle in radialer Richtung beweglich angeordnet sind und von einer Kupplungstrommel abtriebsseitig umschlossen werden. Die Fliehgewichte können durch eine der Fliehkraft entgegenwirkende Schaltvorrichtung außer Betrieb gesetzt werden. device The present invention relates to a switchable centrifugal clutch, at which centrifugal weights on a rotating drive shaft in the radial direction are movably arranged and enclosed by a clutch drum on the output side will. The centrifugal weights can be switched by a switching device that counteracts the centrifugal force be taken out of service.

Im allgemeinen dienen Fliehkraftkupplungen dieser Art dazu, nach dem Erreichen einer bestimmten Drehzahl des Antriebaggregates und der damit erhöhten Anlaufleistung, Maschinen und Geräte aus dem Stillstand anlaufen zu lassen. Weitere Verwendungsmöglichkeiten ergeben sich, wenn die Fliehkraftkupplung die Funktion einer Fliehkraftbremse übernimmt.In general, centrifugal clutches of this type are used after Reaching a certain speed of the drive unit and the thus increased Start-up power, machines and devices start up from a standstill. Further Possible uses arise when the centrifugal clutch performs the function a centrifugal brake takes over.

Eine neue Einsatzmöglichkeit ist gemäß der Erfindung die Absicherung von Antrieben gegen Stromausfall. Bei elektrisch betriebenen mechanischen Aufzügen, Fassadenliften etc. werden hohe Sicherheiten verlangt, welche durch die neue Ausführung erreicht werden, dabei ergibt sich eine einfache, übersichtliche und preisgünstige Ausführung, die Schäden von Personen und von der Anlage weitgehendst fernhalten.According to the invention, a new application is protection of drives against power failure. In the case of electrically operated mechanical elevators, Facade lifts etc. are required high security, which is due to the new design can be achieved, resulting in a simple, clear and inexpensive Execution, which keep damage to persons and from the system as far as possible.

Bei Hebemaschinen ist die Kombination einer Fliehkraftkupplung mit einem Schaltmagneten, welcher im Betriebszustand bzw. beim Anheben von Lasten die Fliehkraftkupplung außer Eingriff hält und welcher bei Stromausfall die Fliehgewichte löst um z. B. einen sich dann absenkenden Aufzug so abzubremsen, daß er nur mit einer zulässigen Geschwindigkeit absinkt, von größter sicherheitstechnischer Bedeutung und vermeidet Unfälle sowie Personen-und Sachschäden.In the case of lifting machines, a centrifugal clutch is combined with a solenoid, which in the operating state or when lifting loads the The centrifugal clutch disengages and which holds the flyweights in the event of a power failure solves z. B. to slow down an elevator that is then lowering, that it only sinks at a permissible speed, which is extremely safe Significance and avoids accidents as well as personal and property damage.

Die Erfindung wirentsprechend einer Ausführungsform in der Skizze dargestellt und nachstehend beschrieben.The invention is shown according to one embodiment in the sketch shown and described below.

An einer nicht näher dargestellten Maschine zum Anheben von Lasten ist auf einer Antriebswelle 1) eines Getriebes, Vorgeleges oder Motors 2) eine Fliehlcraftkupplung 3) montiert, die mit Hebeln 4) versehen ist, welche die Fliehgewichte 5) entgegen der Wirkrichtung der Fliehkräfte ausschalten. Ein Schaltmagnet 6), welcher bei Strombeaufschlagung in Richtung des Pfeiles A) die Mittelwelle 8) verschiebt, ist mit einem Spreizkörper 7), der auf der Mittelwelle 8) gelagert ist, versehen. Bei Betrieb der Maschine wird der Schaltmagnet 6) mit Strom versorgt und die Mittelwelle 8) des Schaltmagneten 6) wird in Richtung A) ausgefahren und verhindert über den Spreizkörper 7), der über die Hebel 4) die Fliehgewichte 5) in ihrer Lage blockiert eine Wirkung der Fliehkraftkupplung 3), da sich die Fliehgewichte 5) nicht anheben können. Fällt nun unversehens der elektrische Strom aus, so bewirkt die von der Maschine angehobene Last ein Absinken, wobei die Drehrichtung in den Antriebselementen im Regelfall geändert wird. Da bei Stromausfall der Schaltmagnet 6) die Mittelwelle 8) mit dem Spreizkörper 7) entgegen der Pfeilrichtung A) zurückzieht werden die Hebel 4) und somit die Fliegewichte 5) entsperrt.On a machine, not shown, for lifting loads is on a drive shaft 1) a gearbox, countershaft or motor 2) a Fliehlcraft coupling 3) mounted, which is provided with levers 4) which counter the flyweights 5) switch off the effective direction of the centrifugal forces. A solenoid 6), which when current is applied in the direction of arrow A) the central shaft 8) moves, is with an expansion body 7), which is mounted on the central shaft 8). When operating the machine the switching magnet 6) is supplied with current and the central shaft 8) of the switching magnet 6) is extended in direction A) and prevented by the expansion body 7), the Via the lever 4) the flyweights 5) blocked in their position an effect of the Centrifugal clutch 3), as the centrifugal weights 5) cannot lift. Falls if the electric current is suddenly turned off, it causes the one raised by the machine Load a drop, with the direction of rotation in the drive elements as a rule will be changed. Since in the event of a power failure, the solenoid 6) connects the center shaft 8) with the Spreader 7) against the direction of arrow A) pulls back levers 4) and thus the flyweights 5) unlocked.

Wird beim Absinken der Last eine bestimmte Geschwindigkeit erreicht, dann heben sich unter Einwirkung der Fliehkraft die Fliehgewichte 5) und bremsen durch Reiben an der mit einem feststehenden Maschinenteil z. B. Motorgehäuse fest verbundenen Trommel 9) die Senkgeschwindigkeit ab.If a certain speed is reached when the load drops, Then the centrifugal force lifts the flyweights 5) and brakes by rubbing on the z with a fixed machine part. B. Motor housing firmly connected drum 9) the lowering speed.

Eine Druckfeder l0) kann zur Unterstützung des Ausrückvorganges auf der Zentrierachse der Mittelwelle 8) angebracht werden.A compression spring l0) can be used to support the disengagement process the centering axis of the central shaft 8).
