Definitions

  • the invention relates to a warp beam disc with a clamping ring which can be fastened to the outer surface of the disc by means of at least two axial fastening screws and can be tensioned by means of at least one clamping screw for releasably clamping the disc which can be screwed together with the clamping ring onto a warp beam tube.
  • the invention further relates to a method for producing such a warp beam disc.
  • Such a warp beam washer is screwed onto the externally threaded ends of a warp beam tube and must be secured against rotation at the desired axial distance from one another.
  • This backup is usually done with a clamping ring that works independently of the Kettbaum disc, e.g. B. is provided with the internal thread required for screwing onto the warp beam tube in order to be connected to the warp beam disc after its processing.
  • the clamping ring consists of a radially slotted clamping bracket, which is clamped in its circumference via a clamping screw guided approximately tangentially to the warp beam tube.
  • This clamp is fastened to the Kettbaum washer using shaped fastening screws of Allen screws, the heads of which lie against the outer surface of the clamping bracket.
  • the clamping ring consists of two clamping disks connected to one another via axial spacing webs, which are also completely machined separately from the Kettbaum washer and then fastened to the outer surface of the Kettbaum washer with fastening screws.
  • a threaded fastener for fastening yarn limiting disks on a warp beam tube or the like by means of a locking nut is subdivided in a plane perpendicular to its axis into a fastening section and a clamping section, which are connected to one another via radially extending web-like connecting sections with a small circumferential width, but are otherwise separated from one another by a spacing slot.
  • Tensioning openings for receiving tensioning bolts extend in partial sections that are aligned with one another through the fastening section and the tensioning section.
  • the lock nut has a centering shoulder in the area of its fastening section for the assembly of the yarn limiting disk concentrically on the warp construction tube.
  • This centering fit requires exact machining and is therefore particularly disadvantageous. Since the disc is only virtually floating on a very narrow ring collar formed by the centering projection, there is a great risk that the disc will be pressed out of the centering fit when subjected to high tilting moments. This danger is particularly great because the yarn limiting disk has no internal thread, that is, it is only pushed onto the warp beam tube with a clear radial distance. Another disadvantage is the need to slit the clamping ring on both sides with special tools except for the web-like connecting sections have to. Finally, the known embodiment is particularly long axially, since the clamping ring already requires a large axial length, which - apart from the length of the centering projection - adds to the axial length of the yarn limiting disk.
  • the invention has for its object to simplify the warp beam described above, in particular with regard to their manufacture.
  • the disc and the clamping ring have a continuous internal thread
  • the clamping ring is supported directly on the outer surface of the disc via at least two supports arranged circumferentially offset, each forming a circular segment-shaped clamping gap, and that at least circumferentially offset in the region of the clamping gaps
  • Two axial clamping screws are arranged in such a way that tightening the clamping screws in the clamping gap area reduces the clear axial distance between the clamping ring and the outer surface of the disk and thereby causes a flank pressure in the thread engagement.
  • the above-mentioned object is achieved according to the invention in that the still unprocessed clamping ring is connected to the disc and then machined together with it, with an inner bore extending through the disc and clamping ring being produced in a single work step and then with a continuous internal thread is provided.
  • the still unprocessed clamping ring can be connected to the warp beam disc and then processed together with it.
  • the warp beam washer machined as a unit washer / clamping ring is then screwed onto the external thread of the associated warp beam tube and secured against rotation by tightening the clamping screws.
  • each fastening screw is passed through a support, preferably three supports, each offset by 120 degrees of circumference, being provided.
  • the supports can be designed in the form of ribs or can also be round. In the latter case, it is expedient if each fastening screw is passed through a support.
  • the supports can in principle be provided on the back of the clamping ring. For manufacturing reasons, however, it appears easier to provide or cast the supports on the outer surface of the pane.
  • the clamping ring lies within an annular groove in the outer pane surface and thus flush within this outer pane surface, and if all screw heads are sunk in the clamping ring.
  • FIG. 1 shows a top view of a warp beam disc 1 to be screwed onto a warp beam tube (not shown in more detail), specifically its outer surface 1a.
  • the disc 1 is cast and has in its outer surface 1a an annular groove 2 which serves to receive a clamping ring 3 shown in Figure 2.
  • annular groove 2 which serves to receive a clamping ring 3 shown in Figure 2.
  • three supports 4 each offset by 120 degrees of circumference, which in the exemplary embodiment shown are round, have a height of 2 to 4 mm and each enclose a pre-cast threaded hole 5 for receiving a fastening screw 6.
  • a pre-cast threaded hole 7 for receiving a clamping screw 8 is provided in the middle between two supports 4.
  • the clamping ring 3 inserted into the ring groove 2 rests on the three supports 4 and has a clear axial distance from the bottom of the ring groove 2 with its underside between the supports 4. This axial distance is referred to below as the clamping gap 9, which extends in the form of a segment of a circle between two supports 4.
  • the clamping ring 3 is fastened in the annular groove 2 with the aid of the fastening screws 6, and is thereby pulled firmly against the supports 4. It is now possible to jointly machine the disc 1 connected to the clamping ring 3 in one setting. In this case, in particular in a single operation, the inner bore extending through the washer 1 and the clamping ring 3 and then an internal thread 10 are produced, with which the warp beam washer 1, together with the clamping ring 3 attached to it, on the external thread of an unspecified one Warp beam tube is screwed on.
  • the three clamping screws 8 are screwed into the associated threaded holes 7 and tightened to such an extent that the clear axial distance between the clamping ring 3 and the outer disc surface 1 a is reduced in the clamping gap area and thereby a flank pressure in the thread engagement between the warp beam Washer 1 and warp beam tube is caused.
  • Figure 2 shows that all screw heads 6a and 8a are arranged sunk in the clamping ring 3.
  • FIG. 3 differs from that according to FIGS. 1 and 2 only in that the clamping ring 3 is not received in an annular groove but rests on the outer surface 1a of the bearing 4, which is somewhat superior.
  • the separate processing of the clamping ring which would otherwise be necessary, is thus eliminated.
  • the Kettbaum disc is ready for installation except for a surface treatment. This ensures exact concentricity.
  • the processing costs are lower and therefore cheaper the entire product. Even existing embodiments can be converted to the system according to the invention with only low costs.
  • the described exemplary embodiments enable the clamping ring to be exchanged due to the two-part design of the disc / clamping ring.
  • the advantage of interchangeability of the clamping ring would no longer exist.
