FIELD: machine building.
SUBSTANCE: invention refers to the roller bearings, in particular, to bevel roller bearings installed on the axles of the railway cars. The roller bearing annular gasket assembly comprises axle (14), journal (12) installed on the end section of axle (14), horn (17), bearing assembly embracing journal (12) and cover (20) attached to the end section of axle (14) for securing the bearing assembly on the journal. The bearing assembly comprises annular gasket (61) adherent to the horn of axle (14) and provided with cut-out (65) turned longitudinally inside, retainer ring (71) and elastic ring (79). Retainer ring (71) features an inner section in the longitudinal direction and outer section (73) in the longitudinal direction and recess (78) between inner section and outer section. Elastic ring (79) is arranged in recess (78) and features a surface turned radially inside, which contacts with annular gasket (61), at that, section (73) is made to enter cut-out (65). The variants have been also proposed to make the annular gasket assembly differing by shapes and arrangement of retainer ring (71) and elastic ring (79).
EFFECT: provision of an assembly to reduce the surface wear of journals and annular gaskets featuring increased stability and ensuring decreased surface wear.
