FIELD: aviation.

SUBSTANCE: invention relates to the field of aviation, in particular to structures of rotary-wing aircrafts. Aircraft (1) contains support element (16; 16’), shaft (12; 12’) rotating around axis (E, E’), a pair of rolling bearings (17; 17’) with inclined contact, installed so that to connect shaft (12; 12’) to support element (16; 16’) with the possibility of rotation around axis (E, E’). Rolling bearings (17; 17’) contain corresponding first rings (18, 19; 18’, 19’) interacting by radial contact with first component (16, 12; 16’, 12’) formed by one of support element (16; 16’) and shaft (12; 12’), corresponding second rings (19, 18; 19’, 18’) interacting by radial contact with second component (12, 16; 12’, 16’) formed by another one of support element (16; 16’) and shaft (12; 12’), and a group of rolling bodies (20; 20’) made with the possibility of rolling along first and second rings (18, 19; 18’, 19’; 19, 18; 19’, 18’). Aircraft (1) additionally contains a pair of preloaded elastic elements (21; 21’) elastically connecting first rings (18, 19; 18’, 19’) to first component (16, 12; 16’, 12’), respectively, in the axial direction.

EFFECT: improvement of operating characteristics and stability of rolling bearings.
