SUPPORT DEVICE OF AVIATION ENGINE ROTARY SHAFT BEARINGS AND AVIATION ENGINE EQUIPPED WITH SUCH DEVICE Russian patent published in 2009 - IPC F16C19/52 F01D21/04 F01D25/16 F02C7/06 

FIELD: machine building.

SUBSTANCE: invention is related to the field of aviation engine engineering. Support device of bearings is intended for holding of rotary shaft (10) of aviation engine installed in bearings (20, 50), which are connected to structure (16) of engine stator with the help of bearing supports (22, 52). At that support device comprises the first bearing (20) retained by support of the first bearing (22), and the second bearing (50) retained by support of the second bearing (52). Support of the second bearing (52) elements (24, 40), which act parallel and at the same time join the second bearing (50) with design (16) of engine stator. Two elements (24, 40) represent different degrees of rigidity and define rigid element (40) and flexible element (24). Rigid element (40) realises connection between the second bearing (50) and structure (16) of engine stator with the help of safety means. Support of the first bearing (22) ends with flange (34), which is fixed in structure (16) of engine stator with the help of safety elements (36).

EFFECT: creation of support device of bearing for rotary shaft of aviation engine, which comprises rigid path of forces transfer and flexible path of forces transfer, which are compatible with possible displacements of this rotary shaft after its disconnection, and which is quite convenient and easy to use.
