Abstract
A safety device for a torque limiter composed of an external body, which is rigidly coupled to the driving shaft for transmitting motion to a working implement and inside which there is a seat for accommodating an internal body which is rigidly coupled to the driven motion transmission shaft and is provided with a series of radial sliding seats for corresponding tabs which can move, in contrast with elastic elements, alternatively between a centrifugal position providing engagement and transmission in corresponding slots formed in the external body and a centripetal position for disengagement from the slots and for stopping the transmission; the movement is activated by means of a corresponding centered plate which forms a protruding ring for wedging and centrifugally pushing the tabs and provides for the in-line interposition, between the internal body and the plate, of pushers for axially pushing the plate into the configuration for forced disengagement from the tabs.
