Definitions

  • the invention relates to an open-end rotor spinning device with a spinning rotor that rotates during operation in a rotor housing that is under vacuum, the driven shaft of which is rotatably supported by means of bearing elements in a housing that is in turn inserted in a machine-side holder.
  • the object of the present invention is to enable the replacement of the spinning rotor with the housing receiving the bearing elements for the rotor shaft in an open-end rotor spinning device according to the preamble of claim 1 without loading the bearings.
  • the housing receiving the bearing elements has an annular flange which extends along the back of the spinning rotor and projects beyond the spinning rotor at least at its largest diameter.
  • the flange also serves as an additional heat sink for the bearings, the operating heat of which is dissipated via the housing receiving the bearing elements and the flange.
  • the flange is adapted to the shape of the spinning rotor and surrounds the spinning rotor at a short distance up to the area of its largest diameter, air turbulence influencing the energy consumption of the device is avoided in the area covered by the flange, so that the energy consumption is reduced.
  • a further energy saving and reduction of the noise level results from the fact that a ring is releasably placed on the flange, which together with the flange forms an open-ended housing which encloses the outer contour of the spinning rotor at a short distance.
  • a quick assembly and disassembly of the ring is made possible in that the ring is connected to the flange by a bayonet lock.
  • the flange is releasably attached to the housing receiving the bearing elements, it is interchangeable with other flange shapes.
  • the housing receiving the bearing elements is expediently axially fixed via the flange.
  • the axial fixation is preferably carried out by a spherical snap lock, which simultaneously fixes the flange and the housing receiving the bearing elements radially elastically and ensures that the damping effect of an elastic support of the housing receiving the bearing elements is retained in the machine-side bracket.
  • the elastic support is preferably carried out by means of O-rings which carry the housing receiving the bearing elements on its circumference.
  • FIG. 1 shows a rotor shaft mounted in a bearing housing with a spinning rotor, which is surrounded by a flange which has been added to a housing and is arranged on the bearing housing, partly in longitudinal section;
  • FIG. 2 shows the unit from FIG. 1 installed in a stationary holder at a spinning position in longitudinal section.
  • Figure 1 shows a spinning rotor 1 with a fiber collecting channel 10, which is rotatably placed on the free end of a rotor shaft 2.
  • the rotor shaft 2 is mounted in ball bearings 20, which are located in a sleeve-shaped housing. This housing, which accommodates the bearing elements, is referred to below as bearing housing 3.
  • the balls of the ball bearings 20 arranged in the vicinity of the two ends of the bearing housing 3 run in guide grooves 22 which are incorporated in the rotor shaft 2.
  • the outer ring of the ball bearings is designated 20 '.
  • the rotor shaft 2 is on its Spinning rotor 1 facing free end driven in any way.
  • An individual electric drive is preferred, for example by an asynchronous motor, the rotor 4 of which is attached to the free shaft end with the interposition of a steel bushing 21.
  • the stator 41 of the electric motor is inserted into a motor housing 5 which is provided with cooling fins (FIG. 2).
  • 0-rings 30 are mounted near the two ball bearings, which are fixed in ring grooves 31.
  • other elastic damping means for example rubber-metal springs, can also be used.
  • Labyrinths 32 and 33 on the two outer ends of the bearing housing 3 seal the bearing.
  • annular flange 60 Arranged on the end of the bearing housing 3 facing the spinning rotor 1 is an annular flange 60 which extends along the rear of the spinning rotor and projects beyond the spinning rotor at least at its largest diameter.
  • the flange 60 is on the inside of the mold adapted to the rear of the spinning rotor 1 and surrounds the spinning rotor 1 up to the area of its largest diameter at a short distance.
  • the flange 60 like the bearing housing 3, is made of a good heat-conducting material and is expediently detachably connected to the bearing housing 3, so that it is interchangeable and spinning rotors of a different shape can be adapted.
  • the flange 60 can also be an integral part of the bearing housing 3.
  • the annular flange 60 By arranging the annular flange 60 on the bearing housing 3, a handle is obtained which makes it possible to insert the bearing housing 3 with the rotor shaft 2 mounted in it and carrying the spinning rotor 1 from the operating side of the machine into a machine-side holder without loading the bearings and pull it out if it is to be exchanged for a bearing housing with a spinning rotor of a different size and / or shape.
  • the flange 60 is also an additional heat sink for the storage system during operation and largely prevents air turbulence on the back of the spinning rotor, which has a favorable effect on the energy consumption of the device.
  • a ring 61 is detachably fastened on the flange 60, so that the spinning rotor 1 is enclosed in a housing which is open at the end.
  • the housing which is formed from the flange 60 and the ring 61 and is designated overall by 6, has an inner contour adapted to the outer contour of the spinning rotor 1 and surrounds the spinning rotor 1 at a predetermined, small distance.
  • the ring 61 also consists of a good heat-conducting material and is connected to the flange 60 in the area of the largest diameter of the spinning rotor 1 by a bayonet lock.
  • the motor housing 5 is inserted into a hole in the rear wall of the spinning chamber housing 7 and has a hole 51 (FIG. 2).
  • the bearing assembly shown in FIG. 1 is gripped on the annular flange 60 or the ring 61 and inserted into the bore 51 until the spring-loaded ball of a ball snap closure 8 flanged to the rear wall of the spinning chamber housing 7 into the ring-shaped extension of the seat on the bearing housing 3 Flange 60 engages.
  • the bearing housing 3, which receives the bearing elements for the rotor shaft 2 is thus axially fixed via the flange 60.
  • Two ball snap fasteners 8 lying opposite one another are provided for secure fixing. Since the diameter of the rotor 4 of the electric motor fastened on the rotor shaft 2 is smaller than the diameter of the bearing housing 3, the insertion of the bearing housing 3 into its holder is not hindered by the rotor 4.
  • This arrangement ensures that during operation, in which the spinning chamber housing 7 is closed in a known manner by a cover (not shown) containing a fiber feed channel and a yarn take-off channel and is under vacuum, there is no relative movement between the spinning rotor 1 and that from the flange 60 and the ring 61 formed housing 6 takes place.
  • the housing 6 can therefore have only a small, precisely defined radial distance from the spinning rotor 1 without the risk of damage.
  • the bearing heat generated during operation is dissipated via the motor housing 5, from which the bearing housing 3 supported by means of O-rings is separated only by a minimal air gap, and additionally via the flange 60 or the housing 6 arranged on the bearing housing 3. This ensures adequate cooling of the device even for high operating speeds.
  • the invention is not restricted to devices in which the rotor shaft is mounted in ball bearings. It can also be used to advantage in other types of storage.
