Definitions

  • Such sleeves are used several times a day in the textile industry and especially in fine spinning machines.
  • a conventional sleeve the only centering takes place by clamping the lower end of the sleeve against the cone of the spindle.
  • three spring-loaded, dome-shaped drivers are usually provided on the spindle circumference at about 5/6 of the spindle height. These drivers do not center the sleeve because the springs can have manufacturing-related deviations.
  • this type of clamping was satisfactory.
  • the trend is an increase in speed and then problems can arise. It has already happened that dome-shaped drivers have flown out of empty spindles at higher speeds due to centrifugal effects.
  • This object is achieved in that at least one sleeve part rests against a spindle part arranged around it.
  • the clamping becomes increasingly stronger when the sleeve outer diameter is expanded. Since a sleeve part is pressed against a part of the spindle by the centrifugal force or centripetal force, the coaxial position of the sleeve is retained.
  • the sleeve is preferably clamped on the spindle in its lower and upper end region. In the lower end area of the sleeve, the sleeve lies against a centering edge. The clamping force can be increased by lip formation in the lower sleeve end area.
  • a broken centering edge is accompanied by a self-cleaning effect, since fly and loose fibers are automatically thrown away.
  • the presence of a protective ring, which protects the lower sleeve clamping area, especially when dropped, is also inventive.
  • the sleeve In the upper area of the sleeve, the sleeve has a pin which is pressed into a central bore in the spindle tip. In terms of manufacturing technology, this is simpler than a recess with a non-circular, for example rectangular, cross section. If you make the pin hollow and also make lips in the hollow pin, the clamping force can also be increased in the upper sleeve area.
  • the lips should have suitable bevels that allow easy insertion on the spindle.
  • a horizontal hole, which cuts the upward hole for the pin, enables the flight of accumulated flight to be automatically ejected.
  • the sleeve, including the protective ring, hollow pin, reinforcing ribs and clamping lips can be easily made in one piece from conventional plastic.
  • a spindle 2 has a lower, slightly conical length section 3, a middle cylindrical length section 4 and a slightly conical, upper length section 5.
  • An underwind crown 8 is also common.
  • a centering edge, or a centering crown 9 is arranged above the underwind crown 8 on the spindle 2.
  • the centering edge 9 can be connected in one piece to the spindle and preferably has three partial edges 10 evenly distributed over the circumference. Through the empty spaces 11 located between the partial edges 10, flight etc. can be flung out when the spindle is empty and rotating.
  • Centrally located in the tip 15 of the spindle 2 is an upward-facing vertical bore 16.
  • a horizontal bore 17 extends through the spindle 2 and intersects the bore 16. The purpose is to eject flight accumulated in the bore 16 when the rotation is empty and rotating Spindle.
  • a one-piece sleeve 21 contacts the spindle in two places, at the top and bottom of the spindle 2.
  • a downward-pointing hollow pin 23 of the sleeve 21 is inserted into the bore 16.
  • the hollow pin 23 has elongated recesses 24 which are open at the bottom, whereby lips 25 are formed. It is obvious that these lips 25 are pressed by the centrifugal force on the spindle part 15 arranged around the lips 25 and the higher the centrifugal force, the tighter the clamping of the sleeve 21 on the spindle 2, whereby the coaxial position of the sleeve is maintained remains.
  • the lips 25 are slightly angled outwards, ie up to a few degrees.
  • the hollow pin 23 is located at a distance below the upper sleeve end 30.
  • reinforcing ribs 31 are provided in the upper sleeve area.
  • Lips 35 are also provided in the lower sleeve end region, in a similar manner as shown and described in FIG. 2. These lips 35 are also slightly angled outwards and have bevels, just like the bevels 27 of the hollow pin 23. These lips 35 are surrounded by the centering edge 9 or from the partial edges 10. A continuous protective ring 39 protects the lips 35 from damage.
