FIELD: transport.
SUBSTANCE: invention relates to flap drive bearing assy operated at aircraft wing. Bearing assy comprises guide path to define two-dimensional way, cylindrical driven bearing with lengthwise axle, shaft and spherical bearing. Said driven bearing with lengthwise axle is confined to follow said way in release of the flap. Shaft extends from driven bearing. Spherical bearing engages shaft end with driven bearing to make the latter revolve about driven bearing lengthwise axle in its motion over aforesaid way. Spherical bearing allows shaft turn about spherical bearing central point to make the flap displace in multiple directions. Guide path can be attached to wing structural element or to flap while linear bearing element can be attached to flap or to wing at the shaft.
EFFECT: possibility to guide the flap in 3D trajectory, decreased slippage and abrasion of driven bearing.
