摘要

Coupling with double clutch, especially for looms, which comprises a first controllable clutch (12), coupling a drive shaft (1), connected to a first, self-driven member of the loom, to a driven shaft (6), connected to a second member of the loom, movable in synchronism with the first and coaxial with the drive shaft, and a second controllable clutch (17), coupling the driven shaft (6)) to an auxiliary motor device (29), which clutches (12,17) are equipped with respective actuating electromagnets (13,18) acting in opposition to elastic means (14,8), in which the clutches each comprise an annular electromagnet (13,18) rigidly connected to a fixed support shell (23), inside which the drive shaft (1) and driven shaft (6) are supported with their axes in a fixed position, which electromagnet is at least partly contained by a rotor (2,9) axially fixed with respect to it and linked with the magnetic flux generated by the electromagnet itself when it is energized, in front of which rotor there is present, on the opposite side from the electromagnet, an annular armature (3,7), axially movable under the action of the magnetic field generated by the relevant electromagnet (13,18) in opposition to the elastic means (14,8), which armatures are rotably locked respectively to the drive shaft and driven shaft and carry the movable members (15,19) of the clutches, in correspondence with which are arranged the fixed members of the clutches (16,20), carried respectively by a flanged element (5) rigidly connected to the driven shaft (6) and by the rotor of the second clutch (9), carrying integral means for connection to the auxiliary motor device (29).
