Abstract: FIELD: aircraft manufacture; designing of combined bearing subunits for unmanned flying vehicles. SUBSTANCE: combined subunit includes upper or lower main rotors and bush embracing the respective shaft and coaxial with it; end portion of shaft and surface of bush embracing it are provided with many radial splines which are external splines for shaft and inner splines for bush; splines of shaft and bush are mutually alternating providing for engagement between shaft and bush for setting it in rotation. Main rotor shaft is provided with main and end cylindrical parts of different diameter: D1 and D2 with taper adapter portion formed between them at angle of inclination beta of surface relative to shaft axis. According to invention, each spline of bush has lower portion bevelled outside forming angle theta relative to axis of bush which is equal to angle beta of taper adapter portion of shaft of main rotor. Bush rests on taper adapter portion of respective shaft by its bevelled lower portions of splines. Distance D3 of such combined subunit between edges of splines of main rotor shaft may be equal to diameter Dl of its main portion in diametral plane. EFFECT: optimization of construction of subunit. 2 cl, 32 dwg.
