Definitions

  • the invention relates to a thread closure for fastening yarn limiting disks according to the preamble of claim 1.
  • yarn limiting disks are provided, which in larger textile machines can have a diameter of up to 1500 mm.
  • very high compressive forces occur which load the yarn limiting disks in the axial direction. Because of the high axial forces that occur, the reliability of the fastening of the yarn limiting disc on the warp beam is of particular importance. Because in textile machines, depending on the application, the wraps have different widths are required, the yarn limiting disks on the warp beam tube or the like must also be easily axially adjustable.
  • a thread closure with the features of the preamble of claim 1 is known from CH-A-498 217.
  • This document discloses a warp beam for weaving machines, which consists of a warp beam tube with limit plates attached to both ends.
  • the limiting disks are fastened to the warp beam tube by means of two rings, of which the first ring is supported on the disk and the second ring has coupling means with which the rings are axially prestressed together with the limiting disk.
  • a yarn limiting disc which has a central, internally threaded bore for screwing the disc to the warp beam tube. Lateral slots are provided in the thread, and adjacent sections of the slotted thread can be clamped against one another by means of a screw. The connecting sections between the slots each extend over approximately a quarter arc and thicken radially outward.
  • the thread lock has the form of a lock nut which is screwed onto the warp beam and is screwed axially to the yarn limiting disk pushed onto the warp tube via two fastening bolts offset by 120 ° in a flange section of the lock nut.
  • the locking nut is radially slotted at a point that is offset by 120 ° relative to the fastening bolts and is provided with a through hole that runs perpendicular to the radial direction. The radial slot in the locking nut can be tightened and thus opened using an adjusting screw the thread of the warp beam tube.
  • the thread limiting disk is thus attached to the warp beam tube using the lock nut.
  • the thread transmission ensures a sufficiently high clamping force so that the yarn limiting disk can no longer be moved in the axial direction.
  • the disadvantage of this arrangement is that, if the yarn limiting disk is not placed correctly and in particular due to one-sided clamping of the lock nut on the warp beam tube, an imbalance in the yarn limiting disk is caused and an increased flattening occurs. Such an imbalance is particularly problematic with large disk diameters during yarn processing.
  • the object of the invention is to carry out the fastening of the yarn limiting disk in such a way that, with easy adjustment of the yarn limiting disk in the axial direction, a simple unbalance-free and flap-free, reliable and permanent attachment is ensured.
  • the tensioning section of the one-piece threaded fastener is pulled in the direction of the fastening section and the yarn limiting disk is fixed on the warp beam tube. Due to the resulting deformation of the lock nut, the lock nut is reliably clamped onto the thread of the warp beam tube and without causing an imbalance, permanent fastening being ensured due to the deformation behavior when the lock nut is tightened.
  • two diametrically opposed clamping openings are formed in the fastening section and the clamping section. With relatively little installation effort, a uniform clamping of the lock nut on the thread of the warp beam tube is ensured.
  • the desired deformability of the locking nut is ensured with a relatively low clamping force if, according to a further embodiment of the invention, the fastening section and the clamping section are connected to one another only via two diametrically opposed connecting sections. In this way, the fastening section and the clamping section are separated from one another over a large part of their circumference by the spacing gap in the case of a symmetrical design, so that the greatest possible deformability exists with a given material thickness.
  • the connecting sections and the clamping openings are preferably arranged offset by 90 ° to one another.
  • two diametrically opposite fastening openings can be formed in the fastening section and the clamping section.
  • the fastening openings are, for example, in the area of the connecting sections.
  • the fastening openings and the clamping openings are formed by the same openings, and the fastening bolts and the clamping bolts are formed by the same bolts.
  • the locking nut is fastened to the yarn limiting disk simultaneously with the locking of the locking nut on the warp beam tube.
  • the locking nut can in particular be clamped in a simple manner in that the clamping openings in the fastening section or in the clamping section have a thread and the clamping bolts are designed as threaded bolts.
  • the clamping openings identical to the fastening openings are preferably smooth-walled bores and the clamping bolts identical to the fastening bolts are designed as threads, with their threaded section in engage the corresponding threaded holes in the thread limiting disc.
  • clamping openings and fastening openings are each separate openings, they are preferably at an angular distance of 90 ° from one another.
  • the clamping openings and the fastening openings can lie on the same pitch circle.
  • the unbalanced mounting of the yarn limiting disks is further facilitated if a circumferential centering projection for the yarn limiting disk is provided on the fastening section.
  • a permanent reliable function of the locking nut is ensured by the fact that it is made of steel.
  • a lock nut 1 consists of a fastening section 2 facing the yarn limiting disk (not shown) and a tensioning section 3, which are only connected via two relatively narrow web-like connecting sections 4, 5, otherwise however, that is, they are separated from one another by a spacing slot 18 over most of their circumference.
  • the locking nut 1 can be screwed onto an unillustrated warp beam tube by means of an internal thread 6, which is provided both in the fastening section 2 and in the tensioning section 3.
  • the lock nut 1 each has a fastening opening 7, 8, through which a threaded bolt (not shown) can be passed in order to engage with its threaded section in corresponding threaded bores in the thread limiting disk to be fixed on the warp beam tube.
  • a threaded bolt (not shown) can be passed in order to engage with its threaded section in corresponding threaded bores in the thread limiting disk to be fixed on the warp beam tube.
  • the two fastening openings 7, 8 are also arranged diametrically opposite one another.
  • the sections 11 ', 12' of the clamping openings 11, 12 are each equipped with an internal thread 15 and 16; using clamping bolts, the fastening section 2 and the clamping section 3 can be clamped together in such a way that a deformation takes place in such a way that, due to deformation of the locking nut 1, it is clamped in the area of its internal thread 6 on the corresponding thread of the warp beam tube.
  • the lock nut 1 has a centering projection 17 in the region of its fastening section 2 for the assembly of the yarn limiting disk concentrically on the warp beam tube.
  • the embodiment of the locking nut 1 shown in FIGS. 3 and 4 differs from that shown in FIGS. 1 and 2 in that no separate fastening openings 7, 8 are provided in the connecting sections 4, 5, but rather with the clamping openings 11, 12 coincide, which are consequently consistently smooth, so that a threaded bolt can engage through it with its threaded portion in corresponding threaded holes in the yarn limiting disc. In this way, when the lock nut 1 is fastened, it is simultaneously jammed on the thread of the warp beam tube by deformation in a single operation.
  • Fig. 6 illustrates that the internal thread of the lock nut 1 can be formed as a flat thread.
