Definitions

  • the present invention relates to a twisting wing according to the preamble of claim 1.
  • twisting spindle known in which a coaxially and rotatably mounted twisting wings is provided.
  • the twisting leaf is braked by a magnetic brake arranged on the twisting spindle, which consists of a ferromagnetic disk and a permanent magnet arranged at a distance therefrom.
  • the permanent magnet is embedded in an adjusting screw made of plastic, which is rotatably arranged in the Zwirnhofflbuchse.
  • the ferromagnetic disc is pressed in a recess at the upper end of the spindle shaft and is in operative connection with the permanent magnet.
  • a hysteresis brake which has a housing made of plastic, in which a magnetic carrier is cast.
  • the magnet carrier serves as a return element for the magnetic circuit formed from permanent magnets.
  • the free pole faces of the permanent magnets point to a magnetic disk which is cast in a plastic carrier plate.
  • the magnetic disk is positively anchored by undercuts and holes, which are formed correspondingly conical in the plastic mass of the carrier plate. When spraying the carrier plate, the conical holes of the magnetic disk are filled with plastic, whereby a positive connection between the two arises.
  • a disadvantage proves that the fixed according to the prior art ferromagnetic disk or Magnetic disk for maintenance purposes not destructive from the spindle shaft or from the support plate is solvable.
  • the invention is therefore based on the object to provide a twisting wing, which is easier to maintain.
  • the connecting elements are designed as snap elements.
  • the snap connection used in accordance with the invention is an extremely material-compatible, easy to assemble and disassemble connection, so that the assembly and disassembly of the twisting spindle is simplified for maintenance purposes.
  • the snap connection allows a non-destructive detachment of the hysteresis disc from the rotary sleeve. Due to the design of the snap elements as integrated components of the rotary socket whose production is simplified and thus more cost effective. The integration of the snap elements as part of the rotary socket is carried out by injection molding as a cost effective and suitable manufacturing process.
  • the snap elements may be formed slotted, have a substantially annular cross-section and be provided with end radially outwardly extending projections, which are the hysteresis disc engage in sections.
  • a radial fixation of the hysteresis disc is effected by the openings of the hysteresis disc in the axial direction penetrating snap elements.
  • the hysteresis disc sections engaging behind projections which are formed as required for the snap connection undercuts of the snap elements, also an axial fixation of the hysteresis disc is achieved.
  • Another advantage is that, in contrast to the use of metallic screws, which could be used for example for releasably connecting the hysteresis disc with the rotary sleeve, the compound according to the invention has no influence on the magnetic field.
  • the projections may be tapered in the axial direction.
  • the tapered design of the end elements arranged on the snap elements projections in the direction of the end facing away from the rotary sleeve end of the snap elements has the advantage that the snap elements can be easily passed through the holes on the hysteresis disc in the arrangement of the hysteresis disc on the rotary sleeve.
  • the snap elements can be arranged offset by an angle between 30 ° and 120 ° to each other in the circumferential direction of the rotary bushing.
  • a mutually offset by 90 ° arrangement of the snap elements may be provided.
  • a rolling bearing on the outer ring
  • the rotary sleeve is frictionally arranged by a snap-fit connection and on the inner ring a setting bush is non-positively connected to the rolling bearing.
  • the adjusting bushing have a cam which is guided in a running on the support sleeve in the circumferential direction, rising groove.
  • the adjusting bush serves for the adjustability of a braking torque to be transmitted, the size of which is adjustable stepwise within a defined range. It can be provided to secure a detent position arranged on the support sleeve positional teeth and arranged on the rotary bushing locking cam.
  • the pre-set braking torque is determined by the positive engagement of the positional toothing and the locking cam.
  • Fig. 1 shows a sectional view of a twisting blade 1, which is arranged on a thread inlet tube 2.
  • the twisting wing 1 is arranged against rotation on the thread inlet tube 2.
  • the twisting wings 1 a support sleeve 3, which is supported on the base of the thread inlet tube 2.
  • a magnetic return 4 and arranged thereon pole magnets 5 are arranged, which are components of an integrated in the twisting wing 1 hysteresis.
  • the hysteresis brake is used to generate an adjustable rotational resistance of the mounting of the twisting wing. 1
  • the twisting wing 1 has a rotary bushing 6 and a hysteresis disk 7 arranged in the rotary bushing 6.
  • the rotary sleeve 6 and the hysteresis disc 7 are arranged coaxially to the thread inlet tube 2 on the support sleeve 3.
  • the rotary sleeve 6 is rotatably mounted on a Einstellbuchse 9, which is also arranged on the support sleeve 3.
  • a rolling bearing 8 is arranged between the adjusting bushing 9 and the rotary bushing 6, with which the rotary bushing 6 is frictionally connected by clipping on the outer ring of the rolling bearing 8.
  • the adjusting bushing 9 is non-positively connected to the inner ring of the rolling bearing 8.
  • the adjusting bushing 9 is guided on the support sleeve 3 by means of a cam 11, which engages in a groove 12 arranged circumferentially about the support sleeve 3. This serves to adjust the braking torque to be transmitted.
  • the adjustability of the braking torque is achieved in that an air gap 15 located between the hysteresis disc 7 and the pole magnet 5 is varied in size by the turning of the adjusting bush 9.
  • the groove 12 has a rising in the circumferential direction of the support sleeve 13 course, so that the pole magnets 5 and the hysteresis disc 7 can be moved toward or away from each other.
  • Securing the detent position is achieved by a arranged on the support sleeve 3 adjusting teeth 14 in conjunction with a arranged on the rotary sleeve 6 locking cam 13.
  • the hysteresis disc 7 is connected by a snap connection with the rotary sleeve 6.
  • cylindrical, slotted snap elements 10 are arranged on the rotary sleeve 6, which serve to receive the hysteresis disc 7, as in Fig. 2 shown.
  • the snap elements 10 are evenly arranged in the circumferential direction of the rotary sleeve 6 on the hysteresis disc 7 side facing at an angle of 30 ° to 120 °, preferably 90 °, offset from one another.
  • the hysteresis disc 7 has the arrangement of the snap elements 10 corresponding through holes 16 which serve the positive reception of the snap elements 10 when clipping the hysteresis disc 7 on the rotary sleeve 6.
  • the snap elements 10 By the snap elements 10, an additional radial fixation in the clipped position of the hysteresis disc 7 is achieved.
  • the snap elements 10 on the end side in the radial direction outwardly utilizatckende projections 17 which engage behind the Hystereseis 7 in applied to the rotary sleeve 6 position in sections.
  • the slotted snap elements 10 each have longitudinal slots 18 offset from one another at an angle of approximately 90 °, which segment the snap elements 10.
  • the segmented snap elements 10 are each pressed together to spread apart again when reaching an end position in which the hysteresis disc 7 on the rotary sleeve 6, so that the projections 17 of the snap elements 10, the hysteresis disc. 7 engage in sections.
