DRIVE SYSTEM OF DEVICE SECTORS FOR AIRCRAFT FUSELAGE MANUFACTURING Russian patent published in 2017 - IPC B64F5/00 B29C33/48 B29C53/82 F16H25/24 

FIELD: physics, instrument engineering.

SUBSTANCE: drive system of the device sectors (2) for the manufacture of the aircraft fuselage, in which the hub(4) for laminating is limited by the exterior surface (5) which forms a rotary body about the axis (7) of symmetry and comprises many sectors (12) with an angular spacing about the axis (7) moving along the slideways between: the extended position for lamination and the retracted position for disassembly. Each sector is provided with a drive system (27) of the screw-nut type, wherein the threaded element (31) rotates about the spinning axis (32) by means of the motor (28). The threaded element (31) contains the inner shaft (33) extending along the spinning axis (32) and an outer tubular portion (34) unstalled along the axis of the inner shaft and provided with the external thread. The limiting means are (38) positioned between the inner shaft (33) and the tubular portion (34).

EFFECT: invention provides the fuselage conformity with the required measures.
