  • This shaft is axially symmetrical and contains two connecting pieces made of electrically conductive material which can be guided to different electrical potentials and a torsion-resistant tube made of an electrically insulating material based on a fiber reinforced polymer.
  • the two fittings are each attached to one end of the insulating tube. From a drive in one of the two connectors introduced force is transmitted through the insulating tube to the second connector and guided from there to an actuator. Because of the arranged between the two connectors insulating tube both connectors can be kept at different electrical potentials, so that such a wave can be used as a rotary shaft, especially in high-voltage electrical apparatus, especially switches.
  • the invention also relates to a method for producing such a shaft and to an apparatus for carrying out the method.
  • the invention nirnmt on a state of the art of waves reference, as described for example in DE 101 18 473 A.
  • the shaft described transmits a rotational movement between two located at different electrical potential machine parts.
  • the shaft carries a trained as insulating widening.
  • a method for producing a fiber-reinforced pressure or tension rod is described.
  • This rod has several layers of plastic fibers, which are fixed in a hardened plastic compound.
  • the fibers are held in a form-fitting manner in an annular manner around the rod axis Recesses, which are formed in conical outer surfaces of two fittings of the rod.
  • a fiber layers overlapping ring is provided. This ring strengthens the positive connection between the fiber layers stored in the recesses and the fittings. It can be transmitted so particularly high pressure or tensile forces.
  • a power transmission element used as a push rod is described in DE 33 22 132 A1.
  • This power transmission element has an electrically insulating, fiber-reinforced plastic rod.
  • Formed in at least one of the two ends of the plastic rod are tapers, into which protrude projections of a sleeve designed as the end portion of a steel connection fitting.
  • the projections are produced after fitting the sleeve on the end of the rod by rolling the sleeve.
  • positive locking between the plastic rod and the connection fitting is achieved in a pushing movement.
  • adhesive which is provided in a gap formed between the sleeve and the rod end, clearance between the rod and fitting is canceled and thus improves the adhesion.
  • a power transmission element in which two metal terminal fittings are spaced apart by an insulating tube based on LCP material is described in EP 899 764 A1. Force fit between the fittings and the insulating tube is achieved by press fit and / or by gluing.
  • the invention solves the problem of creating a wave of the type mentioned, which is characterized by a good transmission behavior, especially when large torques occur, and a method by which such Shaft can be produced in a particularly gentle manner, as well as a device for carrying out the method.
  • a good transmission behavior of the shaft is achieved by an adhesive bond, which is formed by a molded into one end of the insulating cone, which is guided from the lateral surface on the inner surface of the insulating tube and molded from one in one of the two fittings Counter cone and of a cone formed by cone and counter cone and filled with adhesive gap.
  • the cone when the fiber reinforcement of the insulating tube is formed by winding layers of deposited fibers, the cone should cut the layers at an angle of about 10 to 30 degrees with respect to the axis of the insulating tube. It has been shown that then the adhesive layer introduces the force to be transmitted particularly uniformly in virtually all fiber layers, which in particular the transfer of large torques is favored in a particularly effective manner.
  • the fastening means as an adhesive connection, a cavity defined by the inner surface of the insulating tube and the connecting pieces is provided in the shaft, it is advisable to reduce undesired high pressure in the hollow space by means of a pressure compensation channel guided from the outside into the cavity.
  • a good transmission behavior of the shaft is achieved by an embedding, which has as part surbettendes part extending in the direction of the axis of the insulating portion of one of the two fittings and as embedding the end portion of the manufactured in a casting insulating.
  • an embedding By embedding positive engagement and freedom between the embedded connection piece and the insulating tube are achieved and can be so large torques transmitted independently of an adhesive bond. Since this wave is produced by casting, eliminating a machining of the insulating tube and a gluing of the fittings and it can by very Precise control of the casting process a good quality of the insulating tube and thus the shaft, especially in terms of their dielectric and mechanical properties can be achieved.
  • the embedded portion of the connecting piece is designed as a form-locking element. If the positive-locking element has a profile deviating from a circle in the circumferential direction about the axis of the insulating tube, if it is designed in the manner of a polygon, for example, a particularly good transmission behavior is achieved when large torques occur, as for example by a drive shaft for a contact system of a high-current device is required.
  • At least one of the connecting pieces has a guided in the direction of the axis of the insulating longitudinal channel.
  • a used in the manufacture of the insulating tube to support the inner wall elastic molded body can be removed after the manufacturing process through this channel.
  • the fiber reinforcement of the insulating tube is formed by winding layers of deposited fibers, it is advisable to additionally provide radially guided by the fiber layers reinforcing fibers.

  • This process eliminates a decoupled from the manufacturing process of the shaft production of the insulating tube, a machining of the insulating tube as well as the gluing of the fittings. Since the manufacturing process of the insulating tube is directly part of the manufacturing process of the shaft, the manufacturing parameters can be controlled very precisely, whereby a good quality of the shaft, especially in terms of their dielectric and mechanical properties, is achieved.
  • the inner surface and the lateral surface of the tubular fiber body are supported with elastic, gas and liquid-tight moldings prior to introduction into a mold.
  • the shaping process of the insulating tube can then be influenced in a controlled manner.
  • the shaped bodies can be removed without destruction after elastic deformation.
  • Shape and above all quality of the insulating tube and thus the shaft can be influenced in a particularly favorable manner when the moldings are subjected to pressure during curing.
  • unavoidable gas bubbles in the liquid polymer in the fiber body or to be embedded sections of the connecting pieces are largely suppressed by compression and thus significantly improves the dielectric properties of the shaft.
  • the fiber body should be made by winding a plurality of fiber layers on a winding core and the winding core should be formed by the connecting pieces and the elastic body supporting the inner surface of the fiber body.
  • the molded article may then be elastically deformed after curing of the generally thermoset or thermoplastic polymer and removed outwardly through the cavity without destruction. Penetration of liquid polymer into the cavity when impregnating the fiber body is avoided if the inner body of the fiber body supporting elastic molded body is subjected to the impregnation with pressurized gas.
  • 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 supply of the liquid polymer, a fourth of the venting of the mold and a fifth of the Supply of pressurized gas, which pressure gas acts on the impregnated fiber body during curing of the liquid polymer.

  • the adhesive bonds 5 extend from the inner surface 8 of the insulating tube 4 on the lateral surface 7. This is force from the Adhesive 5 introduced directly into all present in the tube cross-section fibers of the fiber reinforcement. It shearing forces between the individual fibers are minimized, which occur in waves according to the prior art, in which an adhesive bond is only present between the lateral surface 7 and connector 2 and 3 respectively.
  • the shaft can not only record large torques, but also large tensile forces. It is therefore not only suitable as a shaft, but also as a pull rod. When used as a tie rod, however, it is advisable to increase the tensile strength to arrange the fibers mainly in the pulling direction.
