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.
- Devices such as mechanical printers, typewriters, etc., which are used in office operations, must be silenced to reduce the environmental impact. For this, they are e.g. B. arranged in the noise-damped housing.
- Such solutions are very complex and are not very suitable for noise reduction for devices in which e.g. Paper sheets or paper webs are led out of the device. It is also possible that only the parts of the device from which the unwanted noise emanates are damped by means of between the device part to be damped and the stationary device frame between switched damping elements. The result is that the wear resistance of these parts is reduced.
- the object on which the invention is based is to implement a noise-damped structural unit of a device, in particular 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 with high noise damping.
- the structural unit consists of a damping material arranged in a carrier block and a metal strip which is arranged on the damping material and is not directly connected to the carrier block and on which the mechanical forces act.
- the support 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 the wear as low as possible.
- the advantage of the invention is, in particular, that the noise reduction and wear resistance of the assembly are achieved with the least cost, with only a very small amount of airborne noise being emitted to the environment and a very low structure-borne noise to the device housing, which, on the other hand, ensures the wear resistance and rigidity of the assembly is.
- 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, for. B. 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. It also prevents the steel strip from vibrating itself and thus making noise in the air.
- Fig. 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. While the damping material 10 is led to the device housing 18, this is not the case with the metal band 12. Here there is an intermediate space 20 between the device housing 18 and the end of the steel strip 12, by means of which it is prevented that sound vibrations can reach the device housing 18 from the metal strip 12.
