Definitions

  • the invention relates to an open-end rotor spinning device with a rotor shaft mounted in the wedge gap of support disks, the free end of which is assigned an axial bearing.
  • This bearing enables the spinning device to be operated at high speeds and allows the spinning rotor to be replaced quickly, since its shaft can be easily pulled out of the bearing and reinserted therein.
  • the bearing is expensive and removal and installation of the support disk bearing, for example to replace support disks with a worn tread, is hindered by the drive means during operation. In this case, the machine must be stopped, which reduces its production output.
  • the object of the present invention is to provide a simplified mounting for the rotor shaft, which also allows the support disks to be removed and replaced during operation of the machine. Another object is to increase the operating speed of the spinning rotor without increasing the running speed of the drive means.
  • the first-mentioned object is achieved in that the rotor shaft is mounted in two bearing points, one of which is formed by support disks arranged near the spinning rotor and the second bearing is an axial and radial force-absorbing bearing which is the free end of the rotor shaft records.
  • the free end of the rotor shaft is reduced in diameter.
  • the bearing at the end of the rotor shaft is expediently a roller bearing which absorbs axial forces in the direction facing away from the spinning rotor, but releases the end of the rotor shaft in the direction of the spinning rotor.
  • the bearing at the end of the rotor shaft is a plain bearing.
  • an axial thrust is generated by setting the axes of the support disks.
  • the axial force securing the spinning rotor in the axial position is generated by a magnet acting on the end of the rotor shaft.
  • a precise axial positioning of the spinning rotor is made possible in that the bearing receiving the end of the rotor shaft is axially adjustable. This is achieved in a simple manner in that the bearing is arranged in an adjustable bearing bush at the end of the rotor shaft. In order to keep the bearing free of vibrations, the bearing is elastically supported in the bearing bush. Characterized in that the bearing at the end of the rotor shaft is preceded by a centering hole, through which the rotor shaft is guided, damage to the bearing when the rotor shaft is inserted and lubricant escaping from the bearing are prevented.
  • the drive means is arranged in the vicinity of the support disks.
  • the rotor shaft with one is preferred Tangential belt driven directly.
  • the rotor shaft can also be driven by a friction roller, a tangential belt or an electric motor, for example, serving as the drive means for the friction roller.
  • a braking device is arranged between the drive means and the bearing at the end of the rotor shaft. Only a small load on the bearing is achieved in that the braking device contains two swivel arms arranged on both sides of the rotor shaft and provided with brake shoes.
  • the object of increasing the operating speed of the spinning rotor without increasing the running speed of the drive means is achieved in that the diameter of the rotor shaft is reduced in the area of the drive means.
  • 1 denotes a rotor shaft which carries a spinning rotor 10 at one end.
  • the rotor shaft 1 is supported in the wedge gap by two support disks 2 and 3, the axes 20 and 30 of which are each freely rotatably supported in a bearing housing 21 and 31.
  • the bearing housings 21 and 31 are detachably inserted in a machine-fixed bearing block 4, for example by means of a clamp lock.
  • this second bearing point is a ball bearing 5, without an inner ring, which receives the free end 11 of the rotor shaft 1.
  • the ball bearing 5, which is preferably used but does not preclude the use of other roller bearings, is able to absorb radial and axial forces. The latter are used to axially fix the rotor shaft 1 and the spinning rotor 10 required and produced in Figure 1 by setting the axes 20 and 30 of the support disks 2 and 3.
  • the ball bearing 5 is arranged in a bearing bush 50 provided with an external thread and embedded therein in a ring 51 made of an elastic material which has a vibration-damping effect.
  • the bearing bush 50 is screwed into a carrier 40, which is fastened to the bearing block 4 or integrated into this.
  • the bearing bush 50 with the ball bearing 5 is thus adjustable in the axial direction, so that the spinning rotor 10 can be positioned axially.
  • the bearing bush 50 On the side facing the spinning rotor 10, the bearing bush 50 is closed by a removable cover 52, in which a conical centering bore 53 is provided for the rotor shaft 1.
  • a cylindrical part 41 adjoins the conical part of the centering bore 53, the length of which is at least equal to the largest diameter of the rotor shaft 1.
  • the centering bore 53 upstream of the ball bearing 5, through which the rotor shaft 1 is guided it is prevented that when the rotor shaft 1 is inserted into the ball bearing 5, it is damaged if it is handled improperly. It also serves to prevent lubricant from escaping from the bearing.
  • the spinning rotor 10 is driven by a tangential belt 6 which is pressed onto the shaft in the front third of the unsupported length of the rotor shaft 1 and thus in the vicinity of the support disks 2 and 3 by means of a tensioning roller, not shown.
  • An angular contact ball bearing 5 ' is preferably used as the rolling bearing, the inner race 11' of which is an integral part of the rotor shaft 1 (FIG. 8).
  • the diameter of the inner race 11 ' is 0.2 to 0.8 times the diameter knife of the rotor shaft 1. While in FIG. 1 the roller bearing is embedded in the bearing bush 50 in an elastic ring 51, the bearing bush 50 is elastically supported in the carrier 40 by means of the ring 51.
  • the free end 11 of the rotor shaft 1 directly adjoining the inner running surface 11 'tapers towards its absolute end 110 and is paraboloid-shaped.
  • the ball treads are lubricated by a lubricant reservoir 54 arranged in the bearing bush 50, into which the tapered free end 11 of the rotor shaft 1, or at least its rounded absolute end 110, is immersed and is closely enclosed by the lubricant reservoir 54.
  • the inclined surface of the free end 11 favors the supply of lubricant to the ball contact surfaces.
  • the passage opening of the bearing bush 50 for the rotor shaft 1 is sealed by a sealing ring 55.
  • the axial thrust in the direction of the bearing receiving the free end of the rotor shaft 1 is not generated by setting the axes of the support disks 2 and 3, but by a magnet 71 which is inserted into the bearing bush 50.
  • the magnet 71 acts on the free end 11 of the rotor shaft 1 and generates the axial force required for the axial securing of the rotor shaft 1.
  • the rotor shaft 1 is reduced in its unsupported length in diameter, so that the spinning rotor 10 is driven at a higher speed without increasing the running speed of the tangential belt. To achieve this, however, it is also sufficient to reduce the shaft diameter only in the area of the drive means.
  • a braking device for the rotor shaft 1 is arranged, which is indicated at 9 and will be described with reference to FIG. 7.
  • the braking device can of course be used in all versions.
  • the rotor shaft 1 in the vicinity of the support disk bearing is driven indirectly by a friction roller 8 which is fastened to a sleeve 81 and is rotatably mounted with the latter on an axis 80 arranged on a pivot lever 82.
  • the tangential belt 6 runs here over the sleeve 81.
  • the rotor shaft 1 is also driven indirectly by the friction roller 8 near the support disks.
  • the friction roller 8 is seated in a rotationally fixed manner on the rotor axis of an electric motor 84 flanged to the swivel lever 82 and is set in rotation by the latter.
  • the braking device already mentioned in FIG. 4 contains two swivel arms 9 and 90 which can be swiveled about fixed axes 91 and 82.
  • Each of the two swivel arms 9 and 90 carries a brake shoe 93 and 94 at the level of the rotor shaft 1.
  • a tension spring 95 attached to the swivel arms 9 and 90 brings the brake shoes 93 and 94 into contact with the rotor shaft 1.
  • a roller 96 prevented, which is arranged on an arm 97 pivotable about an axis 98 and spreads the pivot arms 9 and 90 apart.
  • the rotor shaft can be pulled out of the bearing as before.
  • the support disks can be replaced quickly during operation since there are no obstacles in the way of their removal from the bearing block.
  • the storage also offers enough space to arrange and design the brake means for the rotor shaft so that the bearings are loaded as little as possible when the spinning rotor is stopped.
