Definitions

  • the invention is directed to a tooth set for rollers and support segments of textile machines, such as combing machines, warping and opening rollers for open-end devices, consisting of elements arranged in parallel next to one another, each having a row of teeth arranged on a foot serving for fastening, which elements are made of circular arcs on the outer circumference Tooth segments exist which have a radially inner bearing surface opposite the bearing surface of the roller or the support segment and at least one axially extending recess for receiving a rod-like holding part which runs axially parallel through the tooth segments and connects them and is fastened to the roller or the support segment.
  • Tooth segments exist which have a radially inner bearing surface opposite the bearing surface of the roller or the support segment and at least one axially extending recess for receiving a rod-like holding part which runs axially parallel through the tooth segments and connects them and is fastened to the roller or the support segment.
  • Such devices are known to be garnished with serrated serrated wire in various ways. This is wound onto the cylindrical base body in a helical manner, with the screw turns lying directly against one another in a first embodiment, and thus the width of the base of the sawtooth wire determines the axial distance between the adjacent teeth.
  • the sawtooth wire is glued to the base body.
  • the cylindrical base body produced in this way with the sawtooth wire attached to it is divided in the axial direction.
  • Another known alternative is to wind the sawtooth wire in a helical manner directly onto the cylindrical outer surface of an opening roller, it being possible for adjacent turns to bear against one another or to be arranged at a distance from one another.
  • the sawtooth wire is connected to the roller by gluing, just as is possible with the groove attachment. In many cases, the beginning and the end of the sawtooth wire are jammed in a recessed area of the groove.
  • a combing cylinder which has at least one combing segment which in turn consists of a plurality of parts which extend in the form of a segment, the teeth of which are arranged in a row which is arranged parallel to one another, but which is opposite to one running perpendicular to the longitudinal axis of the cylinder Plane are inclined.
  • the inclination of the wires or tooth segments forming the tooth segments with respect to the cylinder axis should be up to 45 ° and serve to enable particularly fine combing.
  • wound wires or punched-out tooth segments are fastened to the base on support devices which are first introduced in liquid form, harden and are fixed to the basic cylinder with mechanical fastening means, such a hollow cylindrical segment-shaped tooth covering represents a plastic body which cannot be dismantled in itself , but can only be replaced as a complete cylinder segment.
  • GB-A No. 2020330 discloses the combing roller of an open-end spinning device with a prefabricated helical coil made of metallic sawtooth wire, which is drawn onto an outer cylindrical surface of a two-part roller body. The end flanks of this coil are pressed together by stops on the roller body, so that adjacent turns of the coil are held together. At each of the two ends, a flange of the roller body can be penetrated by an axially extending pin by at least one turn of the coil.
  • the toothed segments are arranged in radial planes of the roller and pushed onto the holding parts and are held together in their longitudinal position of the holding parts by cheeks of the supporting segment or the roller in an arrangement of the type described in the introduction.
  • the tooth set consists of a large number of individual elements which are connected to one another and fastened to the support segment or to the roller using the same connecting means.
  • the invention The formation of the teeth also has the particular advantage that the individual tooth segments, as they are no longer deformed when garnishing, like the sawtooth wire, can be hardened. This increases the service life considerably, as the holding times of the machine required to replace the teeth are reduced. However, this is essential for efficient and cost-saving production. In the event of damage to the dental plaque, individual parts of the same can easily be replaced by exchanging individual tooth segments.
  • the toothed segments extend over an angle of a maximum of 180 °. You can then easily be placed from the outside on the support segment or the roller and fastened therein.
  • Another alternative is provided by the invention in such a way that the toothed segments are ring-shaped and are pushed onto a roller body in the axial direction. Which specific embodiment is preferred depends on the circumstances of the individual case. Of course, 90 ° or 60 ° segments or other dimensions can also be used in practice.
  • each tooth segment can engage with these grooves in its foot, which, in contrast to the known embodiments, does not depend on a fixation, for example jamming of the foot, but only for Determination of the level of the individual tooth segments and their distance from each other.
  • the holding part for connecting the tooth segments can consist of a bolt and be anchored in the cheeks of the roller or of the support segment on both sides.
  • the recess receiving the bolt in the tooth segments naturally also has a cross section corresponding to the bolt cross section.
  • the holding part consists of a dovetail profile fastened along a generatrix of the roller, the support segment or the like, onto which the toothed segments, which then have an analog profiled recess starting from their foot, in be pushed in the axial direction.
  • the roller or the supporting segment is optionally designed with a fixed cheek and a cheek to be fastened after the tooth segments have been pushed on.
  • the tooth trimming used to garnish the rollers or supporting segments of textile machines consists of a large number of individual tooth segments 1 which are punched out of a sheet of the desired thickness and subjected to a hardening treatment. 1 extends over an angle a of 180 °.
  • the toothed segment 1 has a circular bore 2 in its center.
  • the tips of teeth 3 lie on a common circular arc.
  • the radially inner support surface 5 is also designed according to an arc around the same center.
  • the embodiment according to FIGS. 3 and 4 differs in that here the angle a is only 90 °, but the toothed segment 1 has a bore 2 in the area of its two outer ends.
  • the tooth segments 1 according to FIGS. 5 and 6 are constructed analogously. However, instead of the bores 2 there is a dovetail-shaped recess 6 or a recess 7 with circular-arc-shaped flanks 8. These recesses 6 and 7 start from the inside bearing surface 5 and extend into the foot 9 of the toothed segment 1.
  • the foot 9 has a radial width 10.
  • the toothed segments 1 are garnished in different ways on the rollers 13 or support segments 14.
  • the roller 13 has a plurality of grooves 15 which run in radial planes and which are incorporated in the roller shell 16.
  • the embodiment according to FIG. 9 differs only in that there are no grooves 15 or 17, rather the roller 13 has a wide recess 21 delimited on both sides by the cheeks 19, into which the toothed segments 1 are inserted next to one another with a coherent contact. Also Here the attachment is carried out by one or more bolts 18 arranged axially parallel.
  • the support segment 14 according to FIGS. 10, 11 and 12 is provided with a circular bearing surface 22 on which the toothed segments 1 rest with their foot 9.
  • the fastening is carried out by means of recesses 2 of bolts 18 penetrating a circular cross section, which are locked laterally on the support segment 14.
  • the embodiment according to FIG. 12 differs in that rods 23 with a dovetail profile are placed on the circular bearing surface 22 and axially parallel. Screws 24 are used, for example, for fastening.
  • the toothed segments 1, which are provided with correspondingly profiled recesses 6 and 7, are pushed onto these rods 23 in the axial direction, with spacers 12 possibly being arranged between the individual toothed segments 1.
  • toothed tooth segments are arranged one after the other in the circumferential direction of the roller or the support segment, for example toothed segments with different tooth shapes or coarse to fine teeth.
