Abstract

Nel presente innesto a rotismo epicicloidale, una corona anulare piatta (7) viene immobilizzata contro uno spallamento interno (8a) della scatola tramite mezzi che comprendono un organo anulare (10) rotativamente e assialmente mobile rispetto a detta corona (7), una camma fissa (12), almeno una controcamma (14) disposta in una gabbia (11) montata in modo da essere vincolata in rotazione al detto organo (10) fra quest'ultimo e detta camma (12), e un elemento (16) di comando di detta gabbia. Preferibilmente, la camma (12) comporta almeno una rampa costituita dal fondo di una cavità (13) inclinato in senso circonferenziale, e nella quale è disposta una sfera (14) che costituisce la controcassa. Un effetto di autoserraggio controllato riduce lo sforzo che si richiede all'operatore. L'innesto può servire a costituire un dispositivo di sicurezza del tipo uomo morto.In the present planetary gear clutch, a flat annular crown (7) is immobilized against an internal shoulder (8a) of the box by means which comprise an annular organ (10) rotatively and axially movable with respect to said crown (7), a fixed cam (12), at least one counter-chamber (14) arranged in a cage (11) mounted so as to be constrained in rotation to said member (10) between the latter and said cam (12), and a control element (16) of said cage. Preferably, the cam (12) comprises at least one ramp constituted by the bottom of a cavity (13) inclined in a circumferential direction, and in which there is a sphere (14) which constitutes the outer casing. A controlled self-locking effect reduces the effort required of the operator. The graft can be used to constitute a dead-man safety device.
