Synchronizing device for electrically actuated coupling

摘要

A synchronizing device for an electrically actuated coupling automatically coupling structural units of processing machine, includes a driving shaft and a driven shaft and two synchronizing members each connected to the assigned shaft for joint rotation therewith. A light emitter is positioned at the first synchronizing member while a light-conducting cable, receiving light from the light emitter, conducts it to a photoelectric detector connected in an electric circuit which actuates the coupling. The angular position of the first synchronizing member relative to the second synchronizing member is adjusted by clamping elements connecting the first synchronizing member to a driving gear of the driving shaft.
