Definitions

  • the invention relates to a coupling for positive rotational driving of a sleeve-shaped thread carrier by a rotatable spindle upper part of a spinning or twisting spindle, with the inside of the thread carrier radially inwardly projecting and at the same time serving the centering of the thread carrier longitudinal ribs and associated with the longitudinal ribs, attached to the spindle top and a groove bottom having longitudinal grooves.
  • a clutch of this kind is through the DE 102 48 930 A1 State of the art.
  • the interlocking longitudinal ribs and longitudinal grooves are used in the known coupling both the rotational driving of the thread carrier and its centering, wherein the longitudinal ribs are supported on the groove bottom.
  • the concentricity of the thread carrier is impaired.
  • the invention is based on the object to avoid this disadvantage and to provide a coupling for the positive rotational driving of a sleeve-shaped thread carrier by a rotatable spindle top part, wherein at the same time a good centering of the thread carrier is ensured.
  • the longitudinal grooves to the spindle tip towards a stop-like constriction which, however, is wider than the width of the longitudinal ribs, which is additionally provided that the longitudinal ribs end to the spindle tip in front of the constriction.
  • the longitudinal grooves are thus significantly wider below the constriction than the longitudinal ribs, so that the thread carrier can be rotated by a small amount on the spindle upper part until the longitudinal ribs bear against the wall of the associated longitudinal grooves. Only then there is the positive rotational driving.
  • the stop-like constriction prevents upward migration of the thread carrier due to yarn tension during operation.
  • the invention also relates to a spindle upper part of a spinning or twisting spindle with longitudinal grooves mounted in the region of the spindle tip and having a groove base as a coupling element for a sleeve-shaped thread carrier.
  • the invention is characterized in that the groove bottom merges at the end of the longitudinal grooves facing away from the spindle tip into a groove-free centering surface for centering the thread carrier.
  • the longitudinal grooves expediently have a stop-like narrowing towards the spindle tip.
  • a spindle attachment containing the longitudinal grooves but not containing the centering surface is placed on the spindle upper part, the spindle attachment containing the spindle tip.
  • the spindle attachment thus serves the positive rotational driving of the thread carrier, while the sliding surface associated with the centering surface is located outside of the spindle attachment.
  • the spindle attachment is expediently injection molded from plastic and attached to the metal spindle end.
  • the invention further relates to a sleeve-shaped, up to an upper end face slightly conical yarn carrier made of plastic, with for the coupling to a spindle upper part of a spinning or twisting spindle from the inner surface of the thread carrier radially inwardly projecting and at the same time the centering of the thread carrier serving longitudinal ribs.
  • the invention is characterized in that the longitudinal ribs are injection-molded with the thread carrier and are subsequently machined on their inner diameter to form a cylindrical centering seat, this being assigned to the centering surface of the spindle top part. It is provided that the initially molded to the upper end face longitudinal ribs are turned off in a region between the end face and a coupling point.
  • a sleeve-shaped thread carrier 2 On a spindle upper part 1 of a spinning or twisting spindle a sleeve-shaped thread carrier 2 is attached.
  • the thread carrier 2 is supported at the bottom against a stop 3 of the spindle upper part 1 axially.
  • the thread carrier 2 is taken during the operation of the spindle by a positive coupling 4 of the rotating spindle upper part 1 in its direction of rotation A.
  • the clutch 4 is located in the upper region of the spindle.
  • the clutch 4 operates without radially movable parts and is a positive connection, which works with longitudinal grooves 5 on the spindle top 1 and longitudinal ribs 6 on the thread carrier 2.
  • longitudinal grooves 5 are present in the example shown, which six longitudinal ribs 6 are assigned. The latter protrude from the inner shell 7 of the thread carrier 2 radially inwardly, engage in operation in the longitudinal grooves 5 and are taken in the direction of rotation A by positive engagement.
  • the width c of the longitudinal grooves 5 in the region of the positive rotational driving of the coupling 4 is greater than the width b of the longitudinal ribs 6, so that the thread carrier 2 can be slightly rotated on the spindle upper part 1.
  • the initially tapered longitudinal grooves 5 extend undercut, so that in each case a stop 9 which narrows the longitudinal groove 5 is formed in both directions of rotation. This results in a constriction 10, which has a width e at its narrowest point, which is wider than the width b of the longitudinal ribs 6, so that the thread carrier 2 can be easily attached and removed from the spindle upper part 1.
  • the stops 9 are used for axial securing of the thread carrier 2 during operation of the spindle, so that the thread carrier 2 does not migrate upward due to the thread tension. Therefore, the longitudinal ribs 6 end to the spindle tip 8 in front of the stop-like constriction 10th
  • the longitudinal grooves and the longitudinal ribs serve not only the positive rotational driving, but also the centering of the thread carrier, wherein the longitudinal ribs are supported on the groove bottom of the longitudinal grooves. It has been shown that the tolerances occurring in the known coupling were not controllable. As a result, the concentricity of the thread carrier on the upper spindle part was impaired.
  • the longitudinal grooves 5 are shorter at their end facing away from the spindle tip 8 than the longitudinal ribs 6 and that the groove bottom 11 merges at this end into a groove-free centering surface 12, against which the longitudinal ribs 6 rest with an adapted sliding fit 13.
  • a separation of functions of centering and rotational driving takes place.
  • the longitudinal ribs 6 engage in the longitudinal grooves 5 the rotational driving takes place, while the groove-free centering surface 12 is used for centering.
  • the groove-free centering surface 12 is used for centering.
  • the spindle upper part 1 can be machined below the longitudinal grooves 5 to an exactly predeterminable diameter which corresponds to the inner diameter d of the longitudinal ribs 6. Because the Longitudinal ribs 6 have to be processed anyway because of the burr existing in the manufacture, this does not require much manufacturing effort.
  • the sleeve-shaped thread carrier 2 tapers slightly conically up to an upper end surface 14.
  • the longitudinal ribs 6 are injection molded together with the thread carrier 2 and then machined on its inner diameter d to a cylindrical centering seat 15. Originally, the longitudinal ribs 6 were over the entire upper area 17, see dash-dot line in FIG. 3 , sprayed to the end face 14, but they were turned off between the end face 14 and the beginning of the coupling 4 and processed to the lower end 16 of the longitudinal ribs 6. This gives a good concentricity of the thread carrier 2.
  • spindle shaft end 19 of the spindle upper part 1 is a longitudinal grooves 5 containing, but not containing the centering surface 12 spindle attachment 18 made of plastic.
  • This spindle attachment 18 contains the spindle tip 8.
