Device for temporarily decoupling two rotating coaxial members

摘要

The invention relates to mechanisms for decoupling two rotating members. The device comprises: a claw 3 sliding on the motor rotating member 1 and subject to the action of a recoil spring 8, an energy reserve spring 15 stronger than the recoil spring and able to disengage the claw, a cam 31 linked to the motor member 1 and adapted to stretch the energy reserve spring, a pawl 25 capable of maintaining the energy reserve spring stretched, and a decoupling control electromagnet 27 linked to the pull for freeing the energy reserve spring. The invention is applicable to the temporary decoupling of two coaxial rotating members, in particular, in the weaving trade, for decoupling the crankshaft of the line and its main motor of the shaft of the dobby and of its main motor of the shaft of the dobby and of its auxiliary control motor.
