Abstract:
A shiftable disk clutch for engaging and disengaging a ship's propeller shaft to and from a drive motor, comprising:two clutch parts rotatable relative to one another about an axis of rotation;at least one circumferentially rigid, non-flexible pressure disk connected to one of the clutch parts so as to be fixed against movement and rigid in every direction, the pressure disk having two end sides with friction surfaces;at least two circumferentially rigid friction disks connected to another of the clutch parts so as to be fixed against movement and rigid in every direction, each of the friction disks having a friction part that is axially movable in a springing-resilient manner relative to the other clutch part against an axial spring force, the friction parts being arranged on both sides of the pressure disk and having friction surfaces located axially opposite to the friction surfaces of the pressure disk;axially acting spring means for applying the axial spring force on the friction parts to disengage the friction parts from the pressure disk;remotely actuatable pressure means operatively connected to one of the clutch parts for axially moving the friction parts of the friction disks relative to the pressure disk, against the springing-resilient force of the friction parts, so as to selectively engage and disengage the friction surfaces of the friction parts and the friction surfaces of the pressure plate; andmeans for centering the two clutch parts relative to one another.
