Definitions

  • the invention relates to a godet for guiding, heating and conveying a thread according to the preamble of claim 1.
  • the known godet has a rotatably mounted godet casing, on the circumference of which one or more threads are guided.
  • the godet casing is of hollow cylindrical design and is supported on a cantilevered support by means of several magnetic bearings.
  • a heating device is arranged next to the magnetic bearings in order to heat the godet jacket.
  • the invention is characterized in particular in that the storage areas of the godet casing can be heated directly.
  • the invention provides the possibility of arranging the coil carriers up to the ends of the godet casing.
  • the coil of the heating device and at least one of the bearing pole windings of the magnetic bearing is formed on the carrier in such a way that the magnetic flux of the coil at least partially covers the bearing pole winding.
  • at least two or more overlapping, overlapping or overlapping magnetic fluxes are generated within a normal plane of the godet casing.
  • a first magnetic flux is generated by the coil carrier with the coil of the heating device and is referred to below as thermal magnetic flux. This magnetic flux causes an induction inside the godet jacket, which leads directly to the heating of the godet jacket.
  • a second applied magnetic flux is generated by the bearing pole winding of the magnetic bearing and used to build up magnetic bearing forces to support the godet casing.
  • the two magnetic fluxes within the godet casing can act in the same direction, radially outwards or in the opposite direction, radially outwards and inwards.
  • the advantageous superimposition of the magnetic fluxes which can extend both in the axial direction and in the radial direction or in both directions, enables the setting of the smallest air gaps, so that low-loss heating of the godet jacket is also possible in one bearing plane.
  • the coil and the bearing pole winding are arranged axially next to one another in accordance with a preferred development of the invention.
  • This embodiment of the invention is particularly advantageous in the opposite direction of action of the magnetic fluxes, for example to magnetically mount a shaft connected to the godet casing.
  • a receptacle is formed by the coil carrier in order to accommodate at least one or more bearing pole windings of the magnetic bearing. This makes it possible to generate the bearing magnetic flux within the thermal magnetic flux, so that there is no mutual interference between the magnetic fluxes.
  • the bearing pole winding and the coil are arranged axially next to one another within the coil carrier.
  • the coil carrier is U-shaped with legs of the same length, which end immediately at a short distance in front of the godet jacket.
  • the bearing magnetic flux generated by the bearing pole winding is guided directly in the godet jacket.
  • the bearing magnetic flux of the bearing pole winding is enclosed by the thermal magnetic flux.
  • the coil and the bearing pole winding are held in the slot base of the coil carrier.
  • the sheet metal winding is assigned a sheet metal which is fastened to the inside of the godet jacket.
  • the bearing pole winding and the lamination thus interact directly to guide the bearing magnetic flux.
  • Shielding means between the sheet metal and the godet casing could result in a further separation of the magnetic fluxes.
  • Another advantage of the development according to claim 6 is that bearing losses, which occur, for example, from the magnetic reversal, are significantly reduced and thus lead to low braking torques within the magnetic bearing.
  • the godet is designed in accordance with the development according to claim 7.
  • the legs of the coil carrier are of unequal length, so that the coil inside the coil carrier and the bearing pole winding are arranged axially next to one another outside the coil carrier.
  • the bearing pole winding acts inwards and thus opposite to the magnetic field generated by the coil.
  • the bearing pole winding is juxtaposed with a hub connected to the godet casing, so that a bearing gap is formed between the hub and the layer pole winding.
  • the bobbin holder at the free end of the support has a radial to just before the inside of the Legs protruding from the godet and an axial leg that protrudes shortly before the inside of the end wall for guiding the thermal magnetic flux. This heats the edge area of the front wall.
  • the layer winding has an insulation that is effective with respect to the coil carrier and / or the coil.
  • the superimposition of the magnetic fluxes can be carried out independently of the direction of flow of the magnetic fluxes. In this way, the pole ends of the layer winding can be arranged axially opposite or radially opposite.
  • the godet is preferably designed according to the features of claim 11.
  • the layer windings are accommodated by the coil carrier, the layer windings being arranged at an angle to one another in a bearing plane.
  • all of the layer windings of a magnetic bearing can advantageously be integrated in the coil carrier.
  • the godet jacket is supported by a magnetic bearing arranged at the free end of the carrier and a magnetic bearing arranged at the clamped end of the carrier.
  • coil carriers are provided with at least one coil, which additionally accommodate one or more layer-pole windings of the magnetic bearings. This enables heating of the godet casing down to the end regions without affecting the storage.
  • the layer-pole windings of the magnetic bearing formed at the free end of the carrier are preferably arranged radially inward with their pole ends, so that a bearing gap is formed between the pole ends of the layer-pole winding and the hub connected to the godet casing.
  • the position-pole windings of the magnetic bearing formed at the clamped end of the carrier are preferably arranged radially outwards in such a way that a bearing gap is formed between the godet casing and the pole ends of the position-pole winding. This ensures a high storage stability of the godet casing.
  • a sensor for monitoring the position of the godet jacket and thus for monitoring the bearing gap is assigned to each layer winding. The bearing pole windings can thus be controlled individually or in groups by a control device.
  • the axial bearing is preferably designed as an axially acting magnetic bearing. However, it is also possible to form the axial bearing by means of roller bearings in an axial or radial design.
  • At least one catch bearing is provided, which can be designed as a radial bearing that is not in contact with normal operation or as an elastically coupled radial bearing.

Abstract

La présente invention concerne une galette servant à guider au moins un fil, comprenant un corps de galette cylindrique creux. Le corps de galette cylindrique creux est monté contre un support de manière à pouvoir tourner librement, grâce à plusieurs paliers. Au moins l'un des paliers se présente sous la forme d'un palier magnétique à action radiale doté de plusieurs enroulements polaires de palier. Contre le support se trouve un dispositif chauffant qui présente au moins un support de bobine équipé d'une bobine, un flux magnétique fermé pouvant être produit entre le corps de galette et le support de bobine équipé de la bobine, afin de produire un échauffement induit du corps de galette. Selon l'invention, la bobine du dispositif chauffant et au moins l'un des enroulements polaires de palier du palier magnétique sont formés contre le support de sorte que le flux magnétique fermé de la bobine et un flux magnétique fermé produit par l'enroulement polaire de palier, se recouvrent au moins partiellement au niveau du palier du corps de galette. Cela rend possible un échauffement du corps de galette même au niveau du palier.
