TELESCOPIC LINEAR ACTUATING MECHANISM OF DOUBLE ACTION WITH DRIVE FROM ONE MOTOR Russian patent published in 2013 - IPC H02K7/06 F02K1/72 F02K1/09 

FIELD: electricity.

SUBSTANCE: telescopic linear actuating mechanism for movement of the first (10b) and second (10a) parts relative to a fixed part (102), comprises a body (101), designed for fixation to a fixed part and for placement of the first stem in it (106), installed without possibility of rotation, but capable of reciprocal displacement with the help of a feed screw (104), connected to facilities (107) of a rotary drive, besides, the first stem is designed for fixation by one end (108) to the first movable part, besides, the first stem serves a support for the second stem (117), located on its extension and designed for fixation by one end (118) to the second movable part, besides, there is a possibility provided to lock rotary motion of the second stem and realisation of its reciprocal motion with the help of the second feed screw (112), stretching via the body and attached to facilities (113, 111) of the rotary drive, besides, according to this invention, driving facilities of both specified stems (106, 117) comprise a motor designed to actuate an input shaft of at least one differential, besides, this differential has at one side the first output shaft connected to the first or second feed screw, and at the other side has the second output shaft connected to the second or first feed screw. Besides, a traction reverser for a gondola of a turbojet engine, comprising at one side devices for diversion of at least a part of one air flow of the turbojet engine, and at the other side, at least one fairing installed as capable with the possibility of reciprocal displacement in direction of substantially parallel longitudinal axis of the gondola from the closing position, in which it provides for aerodynamic integrity of the gondola, and closes devices of diversion to the opening position, in which it opens a channel in the gondola and opens devices of diversion, besides, the movable fairing comprises at least one end part forming a nozzle installed as capable of reciprocal displacement relative to other parts of the fairing, at the same time the proposed reverser of the traction rod also comprises an actuating mechanism for displacement of a movable fairing and a nozzle, arranged in compliance with this invention.

EFFECT: invention provides for the possibility of actuating both stems of an actuating mechanism from one engine with the help of a simple and reliable drive.
