Abstract (en)
[origin: EP2787091A1] There is provided a sealing device for sealing a structure in which a driving part (shaft) is inserted. The sealing device includes: a structure mounting member mounted on a structure, the driving part being inserted into the structure mounting member; a driving part fixing member disposed on the structure mounting member for sealing the driving part inserted thereinto, the driving part being fixed to the driving part fixing member; and a rotation absorbing part provided between the driving part fixing member and the structure mounting member for not transmitting rotation through a relational structure. The sealing device may effectively seal a bin or hopper in which a driving shaft of a screw feeder is inserted while absorbing operational vibration (shaking) and suppressing abrasion by absorbing rotations of the driving shaft and maintaining sealing.
