FIELD: railway.
SUBSTANCE: invention refers to bearings aimed at the installation at the stub shaft (at the journal, at the end of axis), particularly to the improved methods of bearing units sealing to be used in the railway cargo wagon. Unit of roller bearing includes: internal (38), outer (32), wearproof (60) rings and flinger, sealing, rotor (81) and stator (47). The ring (38) has outside-faced bearing race and generally flat axial internal face and the ring (32) has internally-faced bearing race (34) and cylindrical boring. The ring (60) is located close to the ring (38) side, axially inside it. The sealing has first end section (48), intermediate section (27) and second end section. At this the first end section (48) is inserted into the boring (17) of the ring (34). The rotor (81) has basic section (86), radially outside section (82), radially intermediate section (83) and radially internal section (84) which has outer surface parallel to outer surface of the ring (60). The stator (47) has basic section (29), radially outside section (49), radially intermediate section (51) and radially internal section (88). The section (49) (in the second variant of the unit - at least a part of section (49)) is located between the section (27) and section (83) and has outer surface located close to section (27). The section (51) (in the second variant of the unit - at least a part of section (51)) is located between the section (82) and section (83) and at least a part of section (88) is located between sections (83) and (84). Flinger has basic section (57) located (in the second variant of the unit - a part of section (57)) between cylindrical surface of the ring (60) and section (84).
EFFECT: creation of improved sealing of bearing unit which holds lubrication agent inside the sealing unit and contaminants outside it.
