Definitions

  • the invention relates to a winding shaft or a chuck according to the preamble of independent claim 1, see. DE-A-35 33 735.
  • a known winding shaft of this type has a push rod which extends essentially over the entire length of the support tube and which is pneumatically displaced to release the clamping jaws against the counterforce acting in the longitudinal direction of the tension springs.
  • the tension force of several springs must be overcome at the same time when the push rod is being moved, which is why at least two pressure chambers are necessary here, which are arranged in the support tube at one end of the winding shaft.
  • the result of these pressure spaces is that the winding shaft is considerably longer than the available working width.
  • the winding shaft is considerably longer than the available working width.
  • each clamping jaw is assigned two clamping wedges which are symmetrical to one another are cocked and between which a pressure chamber is provided to relax the jaw.
  • the clamping wedges thus arranged in pairs are each loosened by the clamping wedges which are symmetrically assigned to one another.
  • a push rod and the threaded bores in the supporting tube necessary for fastening stops are not required in the winding shaft according to the invention. Since the pressure chambers are not arranged at one end of the winding shaft but rather in the area of the clamping jaws, the working area is not limited by these pressure chambers.
  • the working width can therefore be substantially the same as the total length even with very long winding shafts.
  • the tension springs are supported on the rod arranged in the support tube and the tensioning wedges are mounted thereon.
  • the rod consists of individual segments which are detachably connected to one another.
  • a jaw can be assigned to each segment. Since each bar can be put together with the same segments, the storage is considerably simplified.
  • the rod has a channel through which compressed air can be supplied from outside to the pressure spaces for displacing the clamping wedges and through which these spaces can be relaxed accordingly.
  • the wedge surfaces of the clamping wedges are self-locking and have an inclination angle of, for example, 8 °. This means that a pressure of 6 tons on the clamping jaws is also possible with conventional tension springs.
  • a particularly advantageous embodiment of the pressure chambers is achieved if they have a sleeve, which are each held in a recess in a clamping jaw and in which two clamping wedges are inserted.
  • the winding shaft has a continuously hollow support tube 1, on which a bearing pin 11 is placed at each end.
  • These pins 11 are each with a grub screw 12 fixed on the support tube 1 and serve to support the winding shaft in a known unwinding or reeling device.
  • clamping jaws 3 are inserted, which can be displaced radially outward with one or more winding sleeves 15 with clamping wedges 4.
  • retaining plates 10 are releasably attached to the supporting tube 1 with countersunk screws 10b, on which pressure springs 10a engaging in bores 3b of the clamping jaws 3 are attached.
  • the clamping jaws are pressed inwards when relaxing.
  • the clamping jaws 3 can only be moved radially outwards to a limited extent, since they are in an end position when clamping on the holding plates 10.
  • Each three clamping jaws 3 distributed symmetrically on the circumference of the support tube 1 form a clamping element 2 with two symmetrically arranged clamping wedges 4, a pressure chamber 6, a rod segment 9a and two likewise symmetrically arranged tension springs 7.
  • the rod segments 9a are connected to one another by a connecting sleeve 9c and this is connected at its ends with connecting sleeves 9e to the bearing pins 11.
  • the rod has a channel 13 which, in the case of a bearing journal, leads to the outside to a pressure container 14 or a pressure pump and which is connected to the pressure chambers 6 via radial bores 9f.
  • two counter-tensioning springs 7 are placed on each rod segment 9a, each of which is supported on the one hand on a clamping wedge 4 and on a stop ring 9d of the corresponding rod segment 9a.
  • the two tension springs 7 of a tensioning element 2 tension two tensioning wedges 4, which are slidably guided on the corresponding rod segment 9a, against one another with the same force.
  • the clamping forces of the springs 7 are transmitted via wedge surfaces 3a and 4a into radial forces acting on the clamping jaw 3. Two tension springs 7 thus press three jaws 3 against the inside of the winding tube 15.
  • the inclination of the wedge surfaces 3a and 4a is designed such that they are self-locking, and therefore counteracting forces of the winding tube 15 cannot be transmitted in longitudinal displacements of the clamping wedges 4.
  • a suitable angle of inclination is approximately 8 °.
  • the wedge surface 3a is preferably not flat, but has a radius R of 2 m shown in FIG. 1. As a result, better power transmission is achieved even with comparatively high manufacturing tolerances.
  • For balancing 3 holes 16 are provided in the jaws made of aluminum, in which steel pins 17 are inserted. The shaft can thus be precisely balanced over its entire length.
  • each tensioning element 2 has a pressure chamber 6, which is formed by two tensioning wedges 4, a sleeve 5 and a rod element 9a.
  • Each pressure chamber 6 is sealed to the outside with seals 9d and 9e and connected to the channel 13 of the rod 9 via radial bores 9f. If the pressure in the chamber 6 is increased, the clamping wedges 4 are moved outwards in opposite directions in the longitudinal direction against the clamping force of the springs 7, as a result of which the tension on the clamping jaws 3 is reduced.
  • the sleeves 5 are each held in recesses 3c of the jaws 3. These recesses 3c also form stops for the clamping wedges 4. The clamping wedges 4 can thus be displaced in the longitudinal direction to a limited extent.
  • the pressure in the chambers 6 is reduced, whereupon the clamping springs 7 each move the two clamping wedges 4 of the clamping elements 2 against each other in the longitudinal direction and the clamping jaws 3 radially outwards.
  • clamping elements 2 can thus consist of the same parts and only the number of these clamping elements 2 varies according to the length of the winding shaft, the manufacture and maintenance can be significantly simplified. It is essential that the sleeves are clamped centrally, which is optimally achieved with three symmetrically arranged jaws 3 per clamping element 2.
  • the winding shaft can also be designed as a tensioning head which is supported or driven only at one end and which can have one or more tensioning elements 2. Otherwise, the statements made with regard to FIGS. 1 and 2 apply here.
