A safety device for a torque limiter composed of an external body (2), which is rigidly coupled to the driving shaft (6) for transmitting motion to a working implement and inside which there is a seat (4) for accommodating an internal body (5) which is rigidly coupled to the driven motion transmission shaft (3) and is provided with a series of radial sliding seats (7) for corresponding tabs (8) which can move, in contrast with elastic elements (8a), alternatively between a centrifugal position providing engagement and transmission in corresponding slots (9) formed in the external body (2) and a centripetal position for disengagement from the slots (9) and for stopping the transmission; the movement is activated by means of a corresponding centered plate (10) which forms a protruding ring (10a) for wedging and centrifugally pushing the tabs (8) and provides for the in-line interposition, between the internal body (5) and the plate (10), of pushers (11) for axially pushing the plate (10) into the configuration for forced disengagement from the tabs (8). <IMAGE> |
