Definitions

  • the invention relates to a transmission for driving a Weave of a loom.
  • Weaving machines have so-called subject imaging systems, which serve to warp up or down from the To move out warp level around a so-called drawer to form the entry of a weft thread.
  • the weft insertion systems who work with water or air, for example, have a performance potential for highest weaving speeds on. But this potential can not usually be exhausted, because the existing sumanesysteme resulting from excessive working speed Loads can not withstand.
  • the burdens arise from the accelerations when moving up and down the shafts with which the strands are held.
  • the Movement is by so-called eccentric or Dobby produced. Even if this is as harmonious as possible Movements are aimed at and realized but in the shedding system and the associated gear, which connects the heald frames with the eccentric machines, vibrations. These load all elements of the tray system and lead to premature wear or breakage of components. Litzenbrüche, warp breaks and resulting Machine downtime results from such inflated Charges.
  • CH 558 435 is a weaving sheave drive known to the one between the Webschaft and a Stem transmission arranged linkage heard.
  • the linkage contains a tab in which a shock absorber is installed.
  • the shock absorber can in a variant as a rubber block be educated. This then connects two of this extending rigid halves of the tab.
  • Such a rubber block causes sufficient Vibration damping only at considerable axial compliance, which detrimental to the precision of the shaft movement is. It also provides an additional mass to move in cooperation with other elements, such as playful connections, again source of vibrations can be.
  • CH-PS 549 668 is a linkage for the drive of a weave known in place of conventional Hinge joints spring joints has. These are through Leaf springs or rubber blocks formed. The measure serves the reduction of the otherwise encountered wear on the Joints. In addition, the need for lubrication slow reciprocating joints largely avoided become.
  • EP 0 870 856 A1 is a for driving a Webschaft provided linkage known that over a sprung Tab is connected to the shaft drive. Is to the tab divided into two parts between those Compression spring package is effective.
  • the invention is based Task from which a transmission for transmitting a hinund forthcoming drive movement of a dobby or to create another drive on a hive is, the transmission also very fast shaft movements should allow.
  • This object is achieved with a transmission dissolved in the power transmission path at least one tab with longitudinally oriented sandwich structure consisting of different materials is arranged. At least one of the materials used has vibration-absorbing Properties on.
  • the longitudinal orientation is on the one hand a lightweight low-mass construction and on the other hand achieved a good vibration absorption. It is special possible to give the flap a high axial rigidity, on the other hand, good vibration absorption properties are reachable. This allows the transmission high axial forces to achieve very fast shaft movements, without accepting positioning inaccuracies, the excitation of vibrations as a result of the jerky Movements through the tab can be greatly reduced.
  • the absorber element is planar designed as a closed surface. It can however also as Honeycomb or as a flat, with openings or recesses be provided provided part. It is preferably from a natural or synthetic Elastomer e.g. Natural rubber. It's with the metal or a rigid plastic existing adjacent elements, e.g. area cohesive by gluing or Vulcanization, connected. Alternatively it can also by Rivets or other form-locking connection means held between the other elements of the sandwich assembly be. However, preferred is an arrangement in which the Connection between the two flap parts completely and exclusively by the vibration-absorbing element is created. In such an arrangement, all run in between forces acting on the ends of the tab exclusively through the body of the vibration absorbing element. Detours or other connections between the ends of the flaps, which could be vibration-transmitting, exist Not.
  • the tab may be stiffer wall areas of a metal or a rigid plastic, wherein the Vibration absorptive planar absorber element made of rubber or other elastomer is formed. It may be the longitudinally extending rigid wall areas be wedge-shaped, which is a particularly good Vibration absorption allows. It is preferred that stiff wall areas, for example, as parallel-sided Form plate whose longitudinal edges angled for stiffening. The e.g. square angled edges may be wedge-shaped, i.e. its free edge then runs at an acute angle to the remaining planar rigid wall area and thus to the Longitudinal direction.
