Definitions

  • the invention relates to a hollow spindle for textile machines with a driven spindle attachment for receiving the bobbins, which is non-positively placed on a spindle shaft and is mounted in a bearing sleeve via two roller bearings.
  • Such spindles are required in the textile industry to increase performance in the speed range and to reduce specific energy consumption.
  • Hollow spindles for textile machines are known in which the roller bearings connected directly or via a common sleeve to the machine frame are. To drive through critical speeds, bearings or Bearing sleeves rubber parts arranged. However, rubber has only a limited one Damping effect. So-called energy-saving spindles are also known a third bearing for an outer pot on the bearing sleeve is arranged. This connection is too intensive between the revolving spindle system and the with a lower revolving outer pot system available. The The result is running problems of the spindle in the supercritical area.
  • an energy-saving hollow spindle for textile machines is equipped with a driven spindle attachment to hold the bobbins for the textile thread material.
  • the spindle attachment is non-positively placed on a spindle shaft, on which an inner pot is also non-positively arranged.
  • An outer pot is arranged around the inner pot, which is rotatably mounted on the bearing sleeve for the spindle shaft and is freely movable.
  • the bearing sleeve itself consists of a double tube construction, the two tube parts of which are firmly connected to one another. A sleeve-shaped cavity is provided between the two tube parts of the double tube construction.
  • the upper spindle bearing is arranged at the upper end of the inner tube part and the outer pot bearing is arranged at the upper end of the outer tube part.
  • the outer pot bearing itself can be designed in the usual way, for example as a needle bearing, as a double ball bearing or as a double cylindrical roller bearing.
  • the desired vibration isolation of the bearing seat for the outer pot is essentially achieved by the resulting elasticity between the inner and the outer pipe part of the double pipe construction. It can be useful to dampen the vibrations.
  • Various technical solutions have proven to be suitable as damping agents.
  • a highly viscous material for example a lubricating grease or a paraffin solution, can be arranged as a damping agent in the sleeve-shaped cavity between the inner and the outer tube part.
  • a damping spiral mounted in damping oil in the sleeve-shaped cavity of the double tube construction serving as a bearing sleeve is also possible to arrange a damping spiral mounted in damping oil in the sleeve-shaped cavity of the double tube construction serving as a bearing sleeve.
  • a further embodiment of the invention is achieved in that the sleeve-shaped parts of the double tube construction serving as a bearing sleeve are made of different materials.
  • this is also a solution for retrofitting existing ones Machine systems on high-performance spindles equipped with external pots given.
  • a hollow spindle according to the invention is designed as a winding spindle.
  • This winding spindle is inserted with the spindle shaft 3 into a bearing sleeve 7, this bearing sleeve 7 being held in the lower part in rubber-metal elements which in turn are screwed to the spindle bench of the textile machine.
  • a spindle attachment 1 for accommodating the coil 2 is arranged on the spindle shaft 3.
  • the inner pot 4 has a pot lid 5 with a centrally arranged thread eyelet 6.
  • the bearing sleeve 7 consists of an outer tube part 9 and an inner tube part 10. Both tube parts 9, 10 are firmly connected to one another at their lower end 19.
  • the two pipe parts 9, 10 are separated from one another.
  • a seal 18 is also arranged there when liquid damping agents are used.
  • a bearing 16 for the outer pot 8 and a lower bearing 20 for the spindle shaft 3 are arranged on the outer tubular part 9 in the upper region 15.
  • the bearing 16 for the outer pot 8 is a double row deep groove ball bearing.
  • the inner tubular part 10 encompasses an upper bearing 14 for the spindle shaft 3 at its upper end 13.
  • the sleeve-shaped cavity 11 of the double tube construction between the inner and the outer tube part 9, 10 is used for an oil-hydraulic damping of the vibrations.
  • a generally known damping spiral is arranged in the upper part of the sleeve-shaped cavity 11 as the damping means 12.
  • the sleeve-shaped cavity 11 is also filled with damping oil and closed at the top by a seal.
