SKEW MACHINE Russian patent published in 2018 - IPC B64C27/605 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to the field of aviation, in particular to the structures of control systems for rotors. Skew machine includes a single-row ball bearing installed in the armature armature with a split inner ring resting on the shoulder of the body and on the nut being screwed onto the body. Inside the said housing are two dryers made of antifriction material with spherical internal surfaces, in contact with the slide and fixed with a thread stop. Outer ring of a radial-thrust single-row ball bearing is mounted in the anchor hole and is clamped between the two disks by means of screws, flat outer surfaces of which are in contact with labyrinths, which have annular grooves for placing rings of elastic material, contacting the annular grooves in the body and in the nut. Holes in the stems of the body for connection to the rods of longitudinal and transverse control and holes in the eyelets of the armature for the joints of the pitch rods of the main rotor blades are located in one common plane, and the body is connected by a hingedly reactive thrust with the helicopter body.

EFFECT: provides an increase in resource, increased reliability.
