Abstract
The invention is directed to a sealing arrangement for a machine with a cover having a shaft lead-through for accommodating the shaft, the cover being installed so as to be insulated against structure-borne sound. The machine is equipped with a bearing located outside of the cover and bearing has an end-face facing the cover. The sealing arrangement provides a seal between the bearing and cover and includes two seals which are mounted at the bearing end-face facing the cover so as to be in sealing contact with the shaft. The seals are spaced from each other and located on a ring-shaped part. An annular member is arranged on this ring-shaped part so as to be axially movable and has a flange whose end-face covers the shaft lead-through of the cover and rests in an elastic seal-tight manner against the end-face of the cover.
