Description

Schalldämpfende Schutzhülle für Maschinen Das Patent 967 519 betrifft eine schalldämpfende Schutzhülle für Maschinen, bestehend aus einer biegeweichen Haut, auf die zusätzliche Massen aufgebracht sind. Diese Massen sind in voneinander unabhängige Plättchen unterteilt und zweckmäßigerweise in die Haut eingebettet. Die Haut besteht aus elastischem Material, wie z. B. Gummi, Schaumgummi, Schaumkunststoff od. dgl. Bei der Bemessung solcher Schallschutzhüllen werden die voneinander unabhängigen Massen je nach dem zu entstörenden Frequenzgebiet so abgeglichen, daß das Maximum der Dämmung in diesem Frequenzgebiet liegt.Sound-absorbing protective cover for machines The patent 967 519 concerns a sound-absorbing protective cover for machines, consisting of a flexible one Skin to which additional masses are applied. These crowds are in from each other independent platelets divided and expediently embedded in the skin. The skin is made of elastic material, such as. B. rubber, foam rubber, foam plastic or the like. When dimensioning such sound insulation envelopes, the independent ones Masses adjusted according to the frequency area to be suppressed so that the maximum the insulation is in this frequency range.

Die Erfindung betrifft eine vorteilhafte Weiterbildung einer solchen schalldämmenden Schutzhülle für Maschinen, die dadurch gekennzeichnet ist, daß die Plättchen von unterschiedlicher Größe sind. Es hat sich als zweckmäßig herausgestellt, in einer Schutzhülle nicht ausschließlich Massen gleicher Größe zu verwenden.The invention relates to an advantageous further development of such Sound-absorbing protective cover for machines, which is characterized in that the Platelets are of different sizes. It has been found to be useful not only use masses of the same size in a protective cover.

Die statistische Gewichtsverteilung der in die Schutzhülle einzubettenden Massen wird dabei zweckmäßig so gewählt, daß das Maximum der erzielten Dämmung in dem zu entstörenden Frequenzgebiet liegt. Außer der statistischen Gewichtsverteilung beeinflußt auch die statistische Raumverteilung den Wirkungsgrad der Dämmung, so daß es auch zweckmäßig ist, die statistische Raumverteilung der in die Schutzhülle einzubettenden Massen so zu wählen, daß auch das durch sie bedingte Maximum der Dämmung in dem entstörten Frequenzgebiet liegt.The statistical weight distribution of those to be embedded in the protective cover Masses is expediently chosen so that the maximum of the insulation achieved in the frequency area to be suppressed. Except for the statistical weight distribution the statistical room distribution also influences the efficiency of the insulation, see above that it is also useful, the statistical distribution of space in the protective cover to choose the masses to be embedded in such a way that the maximum of the Insulation lies in the interference-suppressed frequency area.
