Definitions

  • the invention relates to a noise-damped structural unit of a device, in particular the pressure bar of a mechanical printer, on which noise-causing mechanical forces act.
  • the object on which the invention is based is to provide a noise-damped structural unit of a device, in particular of the pressure bar of a mechanical printer, on which mechanical forces which cause noise are to be carried out in such a way that the wear resistance is maintained in the case of high noise reduction.
  • the structural unit consists of a damping material arranged in a carrier block and a metal band arranged on the damping material and not directly connected to the carrier block, on which the mechanical forces act.
  • the carrier block can expediently be attached to the device housing. It must be ensured that the metal band is not connected directly to the device housing.
  • the metal strip is expediently made of steel in order to keep wear to a minimum.
  • the advantage of the invention is, in particular, that the noise reduction and wear resistance of the assembly is achieved with the lowest cost, with only a very small amount of airborne noise being emitted to the environment and a very low level of structure-borne noise to the device housing, while ensuring the wear resistance and rigidity of the assembly
  • the sound emission to the environment is due to the damping material, e.g. Prevents rubber on which the metal band is arranged.
  • the wear resistance is achieved with the help of the metal band arranged on the damping material.
  • the pressure bar of a mechanical printer, e.g. a dot matrix printer used.
  • the pressure beam consists of a damping material 10 which e.g. consists of good damping rubber or plastic, and a metal band 12 arranged on the damping material 10, e.g. consists of a thin hardened steel band.
  • the steel strip 12 can be vulcanized onto the damping material 10.
  • the assembly 10, 12 is on a support block 14 which e.g. consists of aluminum, arranged.
  • the support block 14 can contain a groove 16 into which the structural unit 10, 12 is inserted.
  • the noise damping is achieved with the aid of the damping material 10, by means of which the transmission of the sound vibrations to the support block 14 is largely prevented. Furthermore, it is prevented that the steel strip can vibrate itself and can thus emit noise into the air.
  • Figure 2 shows the arrangement from the front.
  • the support block 14 can be attached to a part of the device housing 18 at both ends. The figure only shows that one end is attached to the device housing 18.
  • the carrier block 14 is correspondingly arranged on the other end of the device housing.
  • During the damping measure material 10 is guided to the device housing 18, this is not the case with the metal strip 12.
