Description

Предлагаемое изобретение относитс  к .механизмам дл  перемещени  подвижного конуса реактивного сопла турбореактивного двигател  посредством шатуна, шарнирно укрепленного на конусе и на шестерне зубчатой цепной передачи, выведенной через обтекатель за пределы реактивного сопла.The present invention relates to mechanisms for moving a movable cone of a jet nozzle of a turbojet engine by means of a connecting rod hinged on a cone and on a gear wheel of a gear chain driven through the fairing beyond the limits of the jet nozzle.

На чертеже схематично изображен предлагаемый механизм в разрезе.The drawing schematically shows the proposed mechanism in section.

Механизм состоит из зубчатой цепной передачи 7, проход шей через обтекатель реактивного сопла, из звездочки 2, смонтированной в направл юшей 3 конуса и соединенной с конусо.м 4 при помощи трубчатого шатуна 5. Направл юща  лежит на двух опорах, образованных фланцем 6, прикрепленным к экрану турбины, и кольцом опоры 7, поддерживающей среднюю часть направл ющей. В рабочей части направл ющей 3 имеетс  паз 8, в котором скользит палец 9, соедин ющий конус 4 со втулкой шатуна 5. Между опорами направл ющей имеютс  вырезы под звездочку 2, котора  смонтирована на оси кронштейна, приваренного внутри направл ющей 3. К ободу звездочки при по.мощи пальца 10 крепитс  вилка 11 шатуна 5. Полный ход конуса происходит при повороте звездочки па 150°. Цепна  передача работает без смазки. Выдвижение и уборка конуса производ тс  приводом от электродвигател  с редуцирование.м числа оборотов. Сопло охлаждаетс  возду.хом, отбираемым от одной из ступеней компрессора.The mechanism consists of a toothed chain drive 7, a neck passage through the jet nozzle fairing, from a sprocket 2 mounted in a direction 3 of a cone and connected to a cone 4 by a tubular connecting rod 5. The guide lies on two supports formed by a flange 6 attached to the screen of the turbine, and the support ring 7 supporting the middle part of the guide. In the working part of the guide 3 there is a groove 8 in which the finger 9 slides, connecting the cone 4 with the connecting rod bush 5. There are cutouts for the sprocket 2, which is mounted on the axis of the bracket welded inside the guide 3. when using the finger 10, the connecting rod fork 11 is fastened 5. The cone's full stroke occurs when the sprocket turns 150 °. Chain transmission runs without lubrication. The extension and cleaning of the cone is driven by an electric motor with a reduction of the number of revolutions. The nozzle is cooled by air drawn from one of the compressor stages.

Предмет изобретени Subject invention

Механизм дл  перемешени  подвижного конуса реактивного сопла турбореактивного двигател , отличающийс  тем, что возвратнопоступательное движение конуса осуществл етс  посредством П1атуна, шарнирно укрепотенного на конусе и на шестерне зубчатой цепной передачи , выведенной через обтекатель за пределы реактивного сопла.A mechanism for mixing the movable cone of a jet nozzle of a turbojet engine, characterized in that the reciprocating movement of the cone is carried out by means of a Ptatun hingedly mounted on the cone and on the gear of a gear chain drive through the fairing outside the jet nozzle.
