Description
Membranantrieb mit Handbetätigung Die Erfindung bezieht sich auf einen pneumatisch- oder hydraulisch betätigten Membranantrieb mit schwenkbarer Antriebsstange und Handbetätigung. Er ist wegen seiner geringen Reibung und seiner einfachen robusten und billigen Ausführung besonders geeignet zum Verstellen von Geräten, z.B. Drosselklappen, Kugelhähnen usw., die von der Industrie für Regelaufgaben eingesetzt werden.Manual actuation diaphragm actuator The invention relates to a pneumatically or hydraulically operated membrane drive with swiveling drive rod and manual operation. It is robust because of its low friction and its ease of use and cheap design particularly suitable for adjusting devices, e.g. throttle valves, Ball valves, etc., which are used by the industry for control tasks.
Antriebe mit schwenkbarer Antriebsstange sind bekannt.Drives with a pivotable drive rod are known.
In der Offenlegungsschrift 1675549 ist ein Kolbenantrieb mit Rollmembrane dargestellt. Seine schwenkbare Antriebsstange ist einerseits starr mit dem Kolben, andererseits mit dem anzutreibenden Hebel über das Gabelgelenk verbunden. Die schwenkbare Antriebsstange hat die Aufgabe den geradlinigen Hub des Antriebes in eine Kreisbewegung des anzutreibenden Hebels zu übertragen.The laid-open specification 1675549 describes a piston drive with a rolling diaphragm shown. Its swiveling drive rod is on the one hand rigid with the piston, on the other hand connected to the lever to be driven via the fork joint. The swiveling one The task of the drive rod is the straight stroke of the drive in a circular motion of the lever to be driven.
Die durch die Schrägstellung der Antriebs stange entstehende Radialkomponente der Verstellkraft wird vom Kolben über einen Gleitring auf das Zylinderrohr übertragen.The radial component created by the inclined position of the drive rod the adjustment force is transmitted from the piston to the cylinder barrel via a sliding ring.
Die wesentlichen Nachteile dieser Anordnung sind die für den Gleitring notwendige saubere Bearbeitung des Zylinderrohres und die Reibung zwischen Gleitring und Zylinderrohr. Die Reibung ist vor allem bei pneumatisch betätigten Antrieben von Nachteil, wenn diese für Regelaufgaben eingesetzt werden.The main disadvantages of this arrangement are those for the sliding ring necessary clean machining of the cylinder tube and the friction between the sliding ring and cylinder tube. The friction is mainly with pneumatically operated drives a disadvantage if these are used for control tasks.
Antriebe mit schwenkbarer Antriebsstange, deren Verlängerung gleichzeitig eine Handbetätigung darstellt, sind nicht bekannt.Drives with swiveling drive rod, their extension at the same time represents a manual operation are not known.
Aufgabe der Erfindung ist es, die Nachteile der bekannten Konstruktion zu beseitigen und den Antrieb mit einer Handbetätigung für beide Hubrichtungen zu versehen.The object of the invention is to overcome the disadvantages of the known construction and to close the drive with one manual operation for both stroke directions Mistake.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Antriebs stange 1 und die Gewindespindel 2 über ein Drucklager 3 gegeneinander drehbar zusammengesetzt sind, wobei die Antriebsstange 1 mit der Antriebsmembrane 4 starr verbunden ist. Die Gewindespindel 2 läuft durch die Mutter 5, die mit dem Hebel 6 über das Gelenklager 7 verbunden ist.The object is achieved according to the invention in that the drive rod 1 and the threaded spindle 2 via a thrust bearing 3 assembled rotatably against each other are, the drive rod 1 is rigidly connected to the drive membrane 4. The threaded spindle 2 runs through the nut 5, which is connected to the lever 6 via the pivot bearing 7 is connected.
Um die Querkraft, die durch die Schrägstellung der Antriebsstange 1 bei der Übertragung der Verstellkraft entsteht, abzufangen, ist die Antriebsstange 1 durch ein sphärisches Lager 8 geführt. Innerhalb des sphärischen Lagers 8 ist die Antriebs stange 1 in einem Gleit- oder Rollenlager 9 gelagert, wodurch die Reibung auf ein Mindestmaß reduziert ist.To the transverse force caused by the inclination of the drive rod 1 when the adjustment force is transmitted is to be intercepted by the actuator stem 1 guided through a spherical bearing 8. Inside the spherical bearing 8 is the drive rod 1 mounted in a sliding or roller bearing 9, whereby the friction is reduced to a minimum.
Bei der Betätigung mit Hand wird die Gewindespindel 2 über das Handrad 1o im Drucklager 3 gedreht. Die Mutter 5 wird, da sie über das Gelenklager 7 gegen Drehung gesichert ist, auf der Gewindespindel 2 je nach Drehrichtung der Gewindespindel in beide Arbeitsrichtungen bewegt. Der über das Gabelgelenk 7 mit der Mutter 5 verbundene Hebel 6 macht somit die gewünschte Hebelbewegung.When operated by hand, the threaded spindle 2 is controlled by the handwheel 1o rotated in thrust bearing 3. The nut 5 is, as it is on the pivot bearing 7 against Rotation is secured on the threaded spindle 2 depending on the direction of rotation of the threaded spindle moved in both working directions. The one connected to the nut 5 via the fork joint 7 Lever 6 thus makes the desired lever movement.
