Coupling device for disconnecting gear trains of e.g. sheet printing machine, has clamping unit to provide clamping forces that are directed transverse to friction surfaces for friction-conclusive torque transmission between spur gear units

摘要

The device has a clamping unit (3) to provide clamping forces that are directed transverse to friction surfaces for a friction conclusive transmission of torque between two spur gear units (1, 2). A chamber unit (4) is formed from two ring units (5, 6), where the unit (6) is axially adjustable opposite to the unit (5) and has a support-bearing section (8) that is mounted on a support shoulder (9). The unit (5) has a release-bearing section (7) that is pushable against a component that is flexibly supported under the effect of the forces to transfer the unit (3) into a release state.
