Clutch e.g. shift clutch, for sheet fed printing machine, has plate, screw and thrust piece for forming and loosening torque-proof connection between surfaces, where plate, screw and piece have thorn, unit and winding to produce heat energy

摘要

The clutch has a pressure plate (8), screw (9), and thrust piece (11), for forming and loosening a torque-proof connection between clutch surfaces, which are formed at clutch halves (1, 3, 4). The plate, screw and the thrust piece have a heating thorn (16), heating unit and heating winding that are provided to produce heat energy. The heating thorn, heating unit and heating winding are arranged at the halves and supply the heat energy to the halves. A heating mandrill is movable from a resting position to an operating position for actuating the clutch.
