Definitions
- the invention relates to a cylinder for high-pressure hydraulics with a cylinder jacket running between a cylinder base and a cylinder head comprising an inner tube and an outer sheath of fiber-reinforced plastic applied to the inner tube.
- the radial compressive forces are transmitted via the thin-walled inner tube to the fiber-reinforced outer jacket, which absorbs these compressive forces without having to fear a leakage of the cylinder, because the outer sheath made of fiber-reinforced plastic remains free of axial tensile loads.
- the axial forces caused by the high-pressure hydraulics are absorbed exclusively by the tie rods.
- a disadvantage of these known cylinders is that the tie rods required for receiving the axial forces do not only increase the construction costs and the cylinder dimensions, but also entail an increase in weight. Presentation of the invention
- the invention is therefore the object of a cylinder for Hochdruck ⁇ hydraulics of the type described in such a way that can be dispensed with simple structural means on the use of tie rods for receiving the axial forces.
- the invention solves the problem set by the fact that the screwed with the Zylinderbo ⁇ , with the outer shell shear-resistant connected inner tube of the cylinder jacket tensile strength acts on the cylinder head.
- the axial forces can be surprisingly absorbed even in a Hoch réellehy ⁇ draulik by the cylinder jacket, if by a shear-resistant connection of the outer sheath made of fiber reinforced plastic with the inner tube corresponding, both in the circumferential direction and in the axial direction effective composite body is created.
- the outer jacket of the cylinder jacket can be adapted in a simple manner to the respective load requirements. With the elimination of tie rods thus very light pressure cylinders are possible, which can be used despite the lightweight design for high pressure hydraulics.
- the inner tube may consist of metal, but also of a polyetheretherketone (PEEK) in a manner known per se, because in both cases not only the axial tensile forces in combination with the outer sheath of fiber-reinforced plastic can be absorbed, but also the outer sheath an immediate load is protected by the hydraulic means, so that the strength properties of the fiber-reinforced plastic can not be affected by penetrating into micropores hydraulic fluid.
- PEEK polyetheretherketone
- connection conditions for the cylinder jacket to the cylinder bottom arise when the outer sheath made of plastic with the cylinder bottom is shear-resistant and the cylinder bottom overlaps the end, so that the axial introduction of force into the outer sheath aus ⁇ not finally on the shear forces between the inner tube and therelyman ⁇ tel done.
- the shear-resistant connection between the outer sheath of fiber-reinforced plastic with the inner tube or the cylinder base can be achieved in a simple manner by an adhesive layer.
- the tensile connection of the cylinder head to the cylinder jacket can be solved in a similar manner as the connection of the cylinder base constructive, but this excludes a subsequent removal of the cylinder head from the cylinder jacket and thus a possible piston expansion.
- the inner tube of the cylinder jacket on the Zylinderkopf ⁇ side have an end annular flange which is overlapped by a cylinder head provided on the union nut, so that with the help of this Koch ⁇ nut the necessary tensile connection between the inner tube of the cylinder jacket and the cylinder head can be ensured can.
- the outer sheath of fiber-reinforced plastic extends to the cylinder head side annular flange of the inner tube.
- the illustrated cylinder has a cylinder bottom 1, a cylinder head 2 and a cylinder extending between cylinder base 1 and cylinder head 2 dermantel 3 on.
- the cylinder jacket 3 is formed by a composite body made of a thin-walled, metallic inner tube 4 and an outer jacket 5 made of fiber-reinforced plastic that is connected to the inner tube 4 in a shear-resistant manner.
- carbon fibers are preferably used. The choice of plastic is naturally made depending on the particular load requirements.
- the inner tube 4 has on the side of the cylinder base 1 a thickened connection portion 6 with a thread 7, by means of which the inner tube 4 is connected in a tensile strength with the cylinder base 1.
- the inner tube 4 is also provided with a thickened end portion 8, which, however, forms an end-side annular flange 9.
- This annular flange 9 is overlapped by a screw-mounted on the cylinder head 2 screw nut 10, so that a tensile connection with the cylinder head 2 is made by the nut 10, which can be removed after loosening the nut 10 from the cylinder jacket 3.
- the outer sheath 5 made of fiber-reinforced plastic extends in the region of the end portion 8 of the inner tube 4 to the annular flange 9 and is therefore enclosed by the union nut 10.
- the outer shell 5 is extended beyond the thickened end portion 6 out and overlaps the cylinder base 1 frontally, whereby the axial connection of the cylinder jacket 3 is advantageously supported on the cylinder base 1, especially if the outer jacket 5 also with the Cylinder bottom 1 is shear-resistant connected by an adhesive layer.
- the inner tube 4 may also be made of plastic, namely of a polyetheretherketone. Also in this case, the inner tube 4 is screwed to the Zylin derêt to achieve a secure axial connection. In addition, the inner tube 4 can be glued to the cylinder bottom.
- the piston 13 with the piston rod 14 may also be made of fiber-reinforced plastic, but this is not mandatory.
- a metallic coating is recommended in order to improve the sealing conditions for a high-pressure hydraulics.
