Abstract

Sistema di bloccaggio (13) per un cuscinetto a rotolamento (1) provvisto di un primo (2), e di un secondo anello (4) accoppiato ad un organo di supporto (5) e presentante due porzioni (8) di estremità, ciascuna delle quali sporge oltre un relativo bordo (9) del primo anello (2); il sistema di bloccaggio (13) è definito da tre sfere (14) interposte tra ciascuna delle porzioni (8) di estremità e l'organo di supporto (5) del secondo anello (4), e da una coppia di ghiere (15) di spinta, ciascuna delle quali è avvitata sull'esterno di una relativa porzione (8) di estremità per forzare le sfere (14) stesse all'interno di una relativa cavità (12) definita dal secondo anello (4) e dal relativo organo di supporto (5). Alternativamente le sfere (14) sono costituite da due corpi anulari (19) di materiale d'attrito deformabile elasticamente.[Figure 1 e 3]Locking system (13) for a rolling bearing (1) provided with a first (2), and a second ring (4) coupled to a support member (5) and having two end portions (8), each of which protrudes beyond a relative edge (9) of the first ring (2); the locking system (13) is defined by three balls (14) interposed between each of the end portions (8) and the support member (5) of the second ring (4), and by a pair of ring nuts (15) thrust, each of which is screwed on the outside of a relative end portion (8) to force the balls (14) themselves inside a relative cavity (12) defined by the second ring (4) and by the relative support (5). Alternatively, the spheres (14) consist of two annular bodies (19) of elastically deformable friction material. [Figures 1 and 3]
