Abstract

Un concentratore di flusso per sistemi di rilevamento della velocità di rotazione tra due organi in rotazione relativa, del tipo costituito da un anello dentato a sezione assiale aperta dotato di un bordo per consentire il montaggio sul cuscinetto di rotolamento e di una tasca per contenere la bobina di rilevamento. Il concentratore di flusso si estende dall'anello fisso del cuscinetto fino all'anello rotante dove individua con la superficie di esso detta tasca; sulla stessa superficie dell'anello rotante del cuscinetto è montata la ruota fonica affrontata alla bobina.
