Abstract RU 2352830 C1

FIELD: engineering industry.

SUBSTANCE: invention refers to the bearing attachment that provides a sealing preventing oil dripping and shaft bearing locking. Attachment point includes housing (2) with race (3) for bearing (1), nut (4), supporting flange (5), and oil deflector that includes oil-deflector ring (6) made together with bowl-shaped lock (7) with protrusions (8) in order to eliminate the turning relative to the shaft (9). On the bearing (1), there installed is adjustment ring (10) with minimum radial clearance (11) relative to oil-deflector ring (6) and with specified axial clearance (12) relative to the bearing (1); at that cylindrical portion of the lock is made so that it can be crimped into slots (15) of nut (4) after the tightening. During the unit operation, for example on the gas turbine engine drive unit, oil tends to penetrate from cavity (16) to cavity (18), which is prevented with minimum radial clearance (11) and oil-deflector ring (6). During the operation oil film preventing oil penetration into cavity (18) is formed in the clearance (11).

EFFECT: improving reliability of gas turbine engine drive units of aviation and ground applications.
