Abstract

Il limitatore (1) comprende un primo corpo (3) portato da un albero motore, un secondo corpo (4) portato da un albero di un utilizzatore, un terzo corpo (5) portato dal primo corpo e scorrevole lungo questo in caso di sovraccarico, mezzi elettrici (2) azionati dal terzo corpo (5) in caso di sovraccarico per bloccare mezzi di movimentazione dell'albero motore, mezzi a molla (6) che premono una parete (12) del terzo corpo verso una flangia (7) del secondo corpo, e delle sfere (8) installate fra la flangia e la parete. Sulla flangia e sulla parete è ricavata una pista anulare (25 e 28) definita da delle sedi (26) di alloggiamento delle sfere e da dei passaggi (27) ricavati fra una sede e l'altra, percorsi dalle sfere in caso di sovraccarico di coppia, e conformati in modo da definire più punti di contatto con le sfere per distribuire su tali punti la pressione di contatto.The limiter (1) comprises a first body (3) carried by a driving shaft, a second body (4) carried by a user's shaft, a third body (5) carried by the first body and sliding along it in case of overload , electric means (2) operated by the third body (5) in the event of an overload to block means for moving the crankshaft, spring means (6) which press a wall (12) of the third body towards a flange (7) of the second body, and balls (8) installed between the flange and the wall. An annular track (25 and 28) is formed on the flange and on the wall, defined by seats (26) for housing the balls and passages (27) formed between one seat and the other, which are traversed by the balls in case of overload of torque, and shaped so as to define multiple points of contact with the balls to distribute the contact pressure on these points.
