Abstract

Un anello esterno di un cuscinetto di ruota presenta nel suo foro una superficie di supporto (7) concentrica all'asse cuscinetto (2), nonché un settore bussola (15) con una superficie di metallo (16) ed un settore flangiato (17) attigua esternamente ad una superficie frontale lato interno (19). Il settore flangiato (17) possiede dei fori filettati (20) passanti assialmente che dal lato interno sboccano in una cavità radiale (27) della superficie mantello (16).Affinché l'anello esterno (1) presenti una resistenza a fatica sufficientemente grande, ogni cavità (27) possiede dei contorni a sezione longitudinale bombati radialmente verso l'interno. La cavità (27) è sistemata quindi radialmente lungo la superficie di supporto (7) ed in una zona della superficie mantello (16) del settore bussola (15) che confina con una superficie frontale lato interno (19) del settore flangiato (17). Tramite compressione del materiale dell'anello esterno (1) fino alla superficie di supporto (7), ogni cavità è ricavata con procedimento a rullatura e/o pressatura fino alla superficie di supporto (7). (Figura 1).An outer ring of a wheel bearing has in its hole a support surface (7) concentric to the bearing axis (2), as well as a bush sector (15) with a metal surface (16) and a flanged sector (17) adjacent externally to a front surface inside (19). The flanged sector (17) has threaded holes (20) which pass through axially and which from the internal side lead into a radial cavity (27) of the casing surface (16). In order for the outer ring (1) to have a sufficiently large fatigue resistance, each cavity (27) has longitudinal section contours rounded radially inwards. The cavity (27) is therefore arranged radially along the support surface (7) and in an area of the casing surface (16) of the bush sector (15) which borders a front surface on the internal side (19) of the flanged sector (17) . By compressing the material of the outer ring (1) up to the support surface (7), each cavity is obtained by rolling and / or pressing process up to the support surface (7). (Figure 1).
