Definitions

  • the degree of deformation ie. the wavelength and / or the amplitude which the damping element of the coil spring imposes changes over the length of the damping element. For example, increasing damping or coupling of the vibrations can be achieved in this way.
  • the damping element is initially deformed relatively little in the direction of the heald from the straight course and the deformation increases in the direction of the anchoring end of the helical spring. With very low dispersion, very good damping is achieved on the damping element.
  • a projection of the core element onto a plane produces a wavy band, the width of which corresponds to the diameter of the core element and the undulating nature of which essentially corresponds to the undulating or helical profile of the core element.
  • the dimensions of the undulating course are expediently defined on this band which is created by projection in the plane.
  • the wavy course shows a wave depth in the projection, measured at an edge of the band, which lies between a wave apex and a wave trough between 0.1 and 3 mm.
  • the strength of this shaft stroke depends on how the diameter ratio between the core element and the inside width of the coil spring is dimensioned and on how strongly the coil spring is to be deflected or pressed against the core element.
  • the distances between the crest of the wave and the trough can be between 2 and 20 mm.
  • the projections or bumps are expediently in one piece with the core element and can either be molded on or molded on if the core element is produced in this form in the master molding process. Another possibility is to produce the bumps by local deformation, for example by squeezing ears. The last option is available if the core element consists of a permanently deformable material, for example metal.
  • connection of the helical spring to the lower or the upper anchoring member can take place in accordance with the prior art.
  • the upward movement of the heald 8 is an inevitable movement which is rigidly forced over the longitudinally inextensible harness cord 4.
  • the opposite direction is a movement caused by the return spring 14 and, in this respect, is inevitable or rigid only to a limited extent.
  • the amplitude of the wavy line i.e. increase the amount of lateral deflection starting from the free end of the core element 22 up to the threaded pin 21. It is hereby achieved that the spring 14 rests with its windings on the first shaft apex with a small lateral force because it is less deformed than on a shaft apex which is closer to the threaded pin 21.
