Safety coupling for connecting pressure discs and friction disc has drive and driven mechanisms with coupling hub, shaft flange and pressure chamber with shearing stopper

摘要

The safety coupling connects two pressure discs (10,11) and friction disc (12) between the drive mechanism consisting of a coupling hub (3) or shaft flange (7) and a driven mechanism consisting of the shaft flange or coupling hub. A pressure compartment (15) is filled with a pressurized medium and possesses a ventilation element consisting of shearing stopper (16) and expander. The mechanism for detachably and frictionally engageable comprises at least one pressure disc and friction disc.
