Abstract

Il cuscinetto (7) porta una corona generatrice di segnali (19), fissata sul suo anello interno (11, 12), e un sensore (21) fissato sul suo anello esterno (9). Il sensore (21) è inglobato in uno schermo formato da un manicotto (24) il quale è munito di un intaglio (27) in cui è alloggiato il sensore (21), mentre una nervatura (31) e atta a proteggere la corona (19). Il manicotto (24) è in materiale elastomerico o plastico ed è fissato sull'anello esterno (9) tramite una bussola (33), che consente un certo slittamento del manicotto (24) rispetto al supporto (14). Il cuscinetto (7) viene confezionato in un'unità di montaggio (6) comprendente un manicotto di imballo (47). Questo viene disposto all'interno del cuscinetto (7) ed è munito di una flangia (49) avente una sede (53) per il connettore elettrico (23) del sensore (21), per consentire la sovrapposizione coassiale delle unità (6) in una pila. La flangia (49) presenta in elemento (52) per favorire la separazione dell'unità (6) dalla pila.(Figura 1).
