Description

Известны воздушные винты с лопаст ми, складывающимис  по направлению оси вращени  винта.Air propellers with blades folding in the direction of the axis of rotation of the screw are known.

Эти воздушные винты, обладают суш,е.ств.9нным . недостатком, заключающимс  в невозможности осуществить изменение мх шага.These propellers have sushi, e.st.9.9nny. the disadvantage of not being able to change the mx step.

В описываемом воздушном вннте этот недостаток устранен благода )  шарнирному соединению лопастей со стаканом, вход щим во втулку винта, и применению черв чной передачи, черв к которого взаимодействует с черв чным сектором на комле лопасти и привод тс  во вращение конической зубчатой передачей.In the described air inlet, this disadvantage is eliminated by virtue of the hinged connection of the blades with the cup entering the screw bush and the use of a worm gear, the worm of which interacts with the worm gear on the butt of the blade and is rotated by a bevel gear.

На чертел е изображен механизм поворота лопасти возд}шного внкта со складывающимис  по направлению оси вращени  лопаст ми.The drawing shows the mechanism for rotating the blade of the air extraction valve with blades folding in the direction of the axis of rotation.

Во втулку / воздушного винта входит стак-ан 2, шарнирно соединг-нный с лопастью-. при помощи болта 4. Комлева  часть лопасти 3 выполнена в виде сектора 5 черв чной шестерни, который нахсдитс  в зацеплении с черв ком 6, установленным на оси 7, закрепленной в стакане 2. На ось 7 насажена также коническа  шестерн  8, котора  находитс  в зацеплении с конической шестерней 9, закрепленной во втулке / винта соосно стакану 2.The sleeve-en / propeller includes a stack-en 2, pivotally connected to the blade-. with the help of a bolt 4. The part of the blade 3 is made in the form of a sector 5 of a worm gear that engages with a screw 6 mounted on an axis 7 fixed in glass 2. An axial gear 8 is also mounted on an axis 7 which is engaged with a bevel gear 9, mounted in the sleeve / screw coaxially glass 2.

Шестерн  9 приводитс  во врап1ение от привода и через шестерню 5 и черв к 6 передают вращение на сектор 5. При этом происходит поворот лопасти относительно болта 4 и складывание ее в направлении оси ринта.Gear 9 is driven from the drive and gear 5 and the worm to 6 transmit rotation to sector 5. At the same time, the blade rotates relative to the bolt 4 and folds it in the direction of the axis of the rint.

СкладыванНе лонастей воздушного винта-производитс  приводом, 1шнематичееки не св занным с приводом, осуществл ющим изменение их шага, что дает возможность использовать существуюш;не констр.укцик йтулок с обычными механизмами дл  изменени  щага лонастей. Folding the propeller's lugs — is produced by a drive, 1 shmatikeki unrelated to the drive, which changes their pitch, which makes it possible to use the existing; not a construction tool with conventional mechanisms to change the fangs.

Предмет изобретени Subject invention

Воздушный винт с лонаст ми, складывающимис  но направлению оси вращени , отличающийс  тем, что, с целью обеспечени  возA propeller with lanyards, folding in the direction of the axis of rotation, characterized in that

можности изменени  шага винта, применены стаканы, вход щие во втулку винта и шарнирно соединенные с лопаст ми, причем комплевые части лопастей выполнены в виде секторов черв чной шестерни, сцепленных с черв ками, оси которых закреплены в стаканах и несут конические шестерни, сцепленные с другими коническими шестерн ми, закрепленными во втулке винта соосно стаканам.the screw pitch can be changed; glasses are used that are included in the screw hub and pivotally connected to the blades; moreover, the complete parts of the blades are made in the form of sectors of the worm gear coupled to the screws, the axes of which are fixed in the glasses and carry bevel gears coupled to others bevel gears mounted in the screw hub coaxially to the glasses.
