摘要
A bearing assembly (1) for coupling articulated trains with a radial spherical plain bearing. The assembly comprises an outer housing (2), a composite bearing race (10) having an inner surface (12), an annular bearing insert (16) and an inner ball (25). The composite bearing race is defined by a plurality of split race portions (10a, 10b) arranged at least partially within the outer housing (2). The bearing insert (16) is preferably split, has a truncated substantially spherical inner bearing surface and is arranged at least partially within the bearing race (10). The inner ball (25) has a truncated substantially spherical outer bearing surface (26) and is rotatably held within the bearing insert (16). The assembly (1) is configured such that, when the longitudinal axis of the inner ball (25) is aligned with the longitudinal axis (7) of the annular bearing insert (16), the spherical outer bearing surface (26) of the inner ball (25) extends beyond the inner spherical bearing surface (18) of the bearing insert (16) in both axial directions.
