Abstract
Description
Die Erfindung betrifft einen Zylinder für Hydraulik oder Pneumatik zur linearen Verschiebung und Krafterzeugung an mechanischen Bauteilen mit einer Kolbenstange, einem Ringkolben, einem Innen- und Außenzylinderrohr sowie Innen-, Außen- und Stirnflansch mit insgesamt vier Druckkammern. The invention relates to a cylinder for hydraulics or pneumatics linear displacement and force generation on mechanical Components with a piston rod, an annular piston, an inner and Outer cylinder tube as well as inner, outer and end flange with a total of four pressure chambers.
Mechanische Bauteile an Maschinen lassen sich mit Hilfe von Hydraulikzylindern oder Pneumatikzylindern mit hoher Kraft linear verschieben. Zur Vermehrfachung des Hubes sind Teleskopzylinder bekannt, die aus mehreren ineinander geschachtelten Zylindern bestehen. Mechanical components on machines can be Hydraulic cylinders or pneumatic cylinders with high force linear move. Telescopic cylinders are used to multiply the stroke known from several nested cylinders consist.
Vor diesem Hintergrund hat sich die Erfindung die Aufgabe gestellt, einen Hydraulik- oder Pneumatikzylinder zu entwickeln, der den Hub verdoppelt und der konstruktionstechnisch, fertigungstechnisch, montagetechnisch, lagerungstechnisch, termintechnisch sowie kosten technisch optimiert ist und den heute erforderlichen Anforderungen besser gerecht wird. Against this background, the invention has set itself the task to develop a hydraulic or pneumatic cylinder that the stroke doubled and the engineering, manufacturing, assembly, storage, scheduling and cost is technically optimized and the necessary today Meets requirements better.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass der
Hydraulik-, Pneumatikzylinder aus folgenden Hauptteilen besteht:
- - zwei Präzisionsstahlrohren
- - einem Innenflansch
- - einem Außenflansch
- - einem Stirnflansch
- - einer axial durchbohrten Kolbenstange
- - einem Ringkolben mit Flansch
- - Dichtungen
- - Verschraubungen
- - two precision steel tubes
- - an inner flange
- - an outer flange
- - an end flange
- - an axially pierced piston rod
- - a ring piston with flange
- - seals
- - screw connections
Alle Teile können rotationssymmetrisch hergestellt werden. All parts can be made rotationally symmetrical.
Die Figuren zeigen in schematischer Darstellung: The figures show in a schematic representation:
Fig. 1 einen Schnitt durch den Zylinder in ausgefahrener Position Fig. 1 shows a section through the cylinder in the extended position
Fig. 2 einen Schnitt durch den Zylinder in eingefahrener Position Fig. 2 shows a section through the cylinder in the retracted position
Der Zylinder hat folgende Funktion:
durch Druckbeaufschlagung auf p1 fährt die Kolbenstange aus
durch Druckbeaufschlagung auf p2 fährt die Kolbenstange ein
durch Druckbeaufschlagung auf p3 fährt der Ringkolben aus
durch Druckbeaufschlagung auf p4 fährt der Ringkolben ein
The cylinder has the following function:
the piston rod extends by applying pressure to p1
pressurizing p2 causes the piston rod to retract
by applying pressure to p3, the ring piston extends
pressurizing p4 causes the ring piston to retract
Die Erfindung weißt folgenden Vorteil auf:
es können gleichzeitig Kolbenstange und Ringkolben
ausgefahren oder eingefahren werden, wobei sich die Ausfahrzeit,
bzw. Einfahrzeit gegenüber herkömmlichen, Zylindern halbiert.
The invention has the following advantage:
the piston rod and the annular piston can be extended or retracted at the same time, the extension or retraction time being halved compared to conventional cylinders.
Genauso kann der Zylinder in jeder Position hydraulisch eingespannt werden. Likewise, the cylinder can be hydraulic in any position be clamped.
Der besondere Vorteil liegt jedoch darin, dass der Zylinder einen doppelten Hub hat und einfach herzustellen ist. The particular advantage, however, is that the cylinder has a double stroke and is easy to manufacture.
