FIELD: mechanical engineering.
SUBSTANCE: invention refers to rolling bearings, particularly to bearings used in aircraft engineering. Rolling bearing (10) consists of external ring (12) with internal surface (18) containing first path of rolling (20), of internal ring (16) containing second path of rolling (32), and of systems of rollers (14) with external surface (22). Also each of rollers (14), external ring (12) and internal ring (16) are designed to freely rotate around their axes of rotation in a working position of the roller bearing, when rollers (14) are arranged between paths of rolling (20 and 32). External ring (12) has lug (48) localised on its internal surface (18) in side direction relative to the said first rolling path. Also here are disclosed the shaft containing the said bearing and the gas-turbine engine containing the said shaft.
EFFECT: improved efficiency of lubrication of boundary bearing by means of forming obstacle for normal flow of lubrication and thereby for control of its flow on external ring.
