Disconnecting overload clutch, comprising a hub () which has axially directed hub recesses () arranged on the periphery thereof, a pressure flange () mounted on the hub () in a rotatable manner with axially directed pressure flange depressions (), wherein in each hub recess (), for example, two rotationally symmetrical transmission bodies () are arranged, which are pressed into the pressure flange depressions () by spring elements () via a switch element (). According to the invention, the switch element () has axially projecting switch element cams () facing the front-end exposed surface () thereof, which in the engaged state transfer the force of the spring elements ()to the transmission bodies () and thus axially engage with the hub recesses (). When disengaging, the switch element () experiences an axial displacement and rotary movement with the switch element cams () in relation to the hub (), so that the switch element cams () are transferred into a position wherein same transfer the force of the spring elements () only onto a support surface () of the hub () with the result that the clutch can freely come to a stop.

Disconnecting overload clutch with transmission bodies arranged in groups

The invention relates to a torsionally rigid, play-free, metal bellows-type, flexible shaft coupling for the torque-transmissive interconnection of two shafts. A metal bellows ( ) has its generally axially flanged-out ends ( &prime;) clamped on the ends of shafts ( ) for frictional engagement. For the provision of a torsionally rigid, torsionally play-free and flexible coupling which can be manufactured inexpensively, which is readily available due to a modular design and which does not affect the drive train dynamics, the ends ( &prime;) of metal bellows ( ) have clamping rings ( ) placed thereon which have slots ( &prime;) therein and are adapted to be compressed by the width of slot ( &prime;) to preferably directly clamp the ends ( &prime;) of metal bellows ( ) down on shafts ( ).
