Definitions
- the invention is based on an element for transmission mechanical force in a rotary and / or pushing movement according to the preamble of claim 1.
- This power transmission element is axially symmetrical formed and contains two feasible to different electrical potentials Connecting pieces of electrically conductive material as well as a torsion and / or Tensile loadable tube made of an electrically insulating material on the base a fiber reinforced polymer.
- the two connectors are each on attached to one of both ends of the insulating tube. From a drive in one of both Connection introduced force is transmitted through the insulating tube to the second Transfer connector and guided from there to an actuator. Because of the arranged between the two connectors insulating Both connectors can be at different electrical potentials be held, so that such a power transmission element mainly in high-voltage electrical apparatus, in particular switches, as Push rod or can be used as a rotary shaft.
- the invention also relates to a method for producing such Power transmission element and a device for carrying out the Process.
- the invention takes a prior art of Power transmission elements reference, as described in DE 33 22 132 A1.
- An illustrated in this patent publication and as a push rod used power transmission element has an electrically insulating, fiber-reinforced plastic rod on.
- In at least one of both ends of the Plastic rods are formed in tapers, in which projections one as Protruding sleeve executed end portion of a steel connection fitting.
- the projections are after attaching the sleeve to the end of the rod generated by rolling the sleeve. This is when a pushing movement Positive connection between the plastic rod and the connection fitting achieved. Furthermore, by adhesive, which in between a sleeve and rod end formed gap is cleared, clearance between rod and fitting and so the adhesion improved.
- a power transmission element in which two metal connection fittings are spaced apart by an insulating tube based on LCP material, is described in EP 899 764 A1. Adhesion between the fittings and the Insulating tube is achieved by press fit and / or by gluing.
- the invention as defined in claims 1 to 19 solves the Task to provide a power transmission element of the type mentioned, which is characterized by a good transmission behavior, especially when occurring great torque, and a method by which such Power transmission element can be produced in a particularly gentle manner can specify, as well as a device for carrying out the method.
- a good Transmission behavior of the force transmission element by an adhesive bond achieved, which is formed by a molded into one end of the insulating tube Cone, which is guided by the lateral surface on the inner surface of the insulating tube as well as from a formed in one of the two fittings counter-cone and of a cone and counter cone formed and filled with adhesive Gap.
- the adhesive gap from the inner surface of the insulating tube whose lateral surface extends both when pulling and when turning Force from the adhesive bond directly in all existing in the pipe cross-section Fibers introduced.
- the fiber reinforcement of the Isolierrohrs formed by winding layerwise deposited fibers, so should the Cone the layers at an angle of about 10 to 30 °, relative to the axis of the insulating pipe, cut. It has been shown that then the adhesive layer to transferring force particularly uniformly into practically all fiber layers, whereby in particular the transmission of large torques in particular is favored effectively.

- the shaping process of the Isolierrohrs are influenced controlled.
- the Moldings are removed without damage after elastic deformation.
- Shaping and above all quality of the insulating tube and thus of the Force transmission element can be influenced in a particularly favorable manner, when the moldings are subjected to pressure during curing.
- the amount of pressure here are unavoidable gas bubbles in the liquid Polymer, in the fiber body or to be embedded sections of the Compression pieces largely suppressed by compression and so the dielectric properties of the power transmission element quite essential improved.
- the fiber body should by winding several fiber layers are made on a winding core and should the Winding core of the fittings and the inner surface of the fiber body be formed supporting elastic molded body.
- the molding can then be cured after curing in general duromer or thermoplastic polymer and elastically deformed by the Cavity to be removed to the outside non-destructively. An intrusion of liquid polymer in the cavity when soaking the fiber body is avoided when the inner surface of the fiber body supporting elastic Molded body is impregnated with compressed gas prior to impregnation.
- An advantageous device for carrying out the inventive Method comprises a mold having at least five openings, of which serve a first and a second of the implementation of the two connectors, a third of the feed of the liquid polymer serves, a fourth of the venting of the Casting mold and a fifth of the supply of compressed gas, which compressed gas during Hardening of the liquid polymer forming the impregnated fiber body acts.
- the device also includes a winding tool with a Winding core, which of the two connectors and one between the two connecting pieces arranged elastic molded body is formed and the inclusion of the fiber body is used.

From one to earth potential arranged, not shown drive can then force on the shaft 1 to a to be driven element, for example, a contact arrangement of a High voltage switching device to be transmitted.
- a to be driven element for example, a contact arrangement of a High voltage switching device to be transmitted.
- the attachment is achieved by two adhesive bonds 5 each formed from one in one end of the Insulating tube molded cone 6, from the lateral surface 7 on the inner surface 8 of the insulating tube 4 is guided and of a in the connector 2 and 3, respectively molded counter cone 9 and one of cone 6 and counter cone 9 formed and filled with adhesive gap 10.
- the adhesive bonds 5 extend extending from the inner surface 8 of the insulating 4 on the lateral surface. 7
- force from the adhesive bond 5 directly into all in the pipe cross-section existing fibers of the fiber reinforcement initiated. It's shearing forces minimized between the individual fibers, which in transmission elements occur in the prior art, in which an adhesive bond only between lateral surface 7 and connector 2 and 3 is present.
- the Power transmission element not only large torques, but also large Absorb tensile forces. It is therefore not only as a wave, but also as a wave Pull rod suitable. However, when used as a tie rod, it is recommended that To increase the tensile strength to arrange the fibers mainly in the pulling direction.
- the fiber reinforcement of the insulating 4th formed by winding layers deposited fibers 11, the cone 6 should be the Fiber layers 11 at an angle of about 10 to 30 °, relative to the axis of Insulating tube, cut. It has been shown that when loading the Power transmission element 1 with torque the adhesive bond 5 then to transmitting force in virtually all fiber layers 11 simultaneously and uniformly initiates.
