Abstract
The invention discloses a variable pitch propeller mechanism. Paddles (1) are assembled to a propeller hub (3) through propeller bases (2) and can rotate on the propeller hub (3), and the propeller hub (3) is directly assembled to a rotor of a motor (6). One end of a transmission shaft (4) is connected with the paddle bases in an assembled mode through variable pitch pull bars (5), and the other end of the transmission shaft (4) penetrates through a central hole (8) of the motor (6) and is directly connected with a rotating disc of an inclinator (10) or is connected with the rotating disc of the inclinator (10) through operating pull bars (11).
Description
Technical field
The present invention relates to a kind of wind stick, particularly a kind of variable-pitch propeller paddle mechanism of gyroplane.
Background technology
The wind loading rating of well-known multiaxis gyroplane is far below helicopter, what helicopter adopted is variable-pitch propeller, is the pitch lift fuselage by change screw, fixing screw and multiaxis gyroplane adopts, so can only promote aircraft by changing motor speed. The variable-pitch propeller paddle mechanism of helicopter is too complicated again, if although the variable-pitch propeller of helicopter is installed on multiaxis gyroplane and can improve wind resistance power because too many transmission mechanism also can increase a lot of destabilizing factors to aircraft.
Summary of the invention
The object of the invention is to solve the deficiency of above-mentioned technology, a kind of variable-pitch propeller paddle mechanism of gyroplane simple in structure is provided.
For achieving the above object, the present invention by the following technical solutions.
Described variable-pitch propeller paddle mechanism is made up of blade, blade root, propeller hub, pitch-change-link, power transmission shaft, inclinator, motor and operating mechanism etc. Blade is assemblied on propeller hub and can on propeller hub, be rotated by blade root, described propeller hub is directly assemblied on rotor, and described power transmission shaft one end is directly connected the rotating disc of inclinator through motor center hole by pitch-change-link with by the root assembly connection other end or connects the rotating disc of inclinator by control operating rod. When a described power transmission shaft is handled N blade displacement simultaneously, power transmission shaft directly connects the rotating disc of inclinator through motor center hole; When a power transmission shaft is only handled a blade displacement, power transmission shaft is made as Hollow Transmission Shafts, due at least two blades of screw, so N root power transmission shaft intert after being inserted in assembling and connect the rotating disc of inclinator by control operating rod through motor center hole according to size. Described motor is provided with centre bore, be that motor housing, central shaft straight line whole process penetrate hollow design, described power transmission shaft can inject the interior motor that also passes of central shaft of motor, described inclinator is exactly to make the power transmission shaft of rotation become non-rotating state by bearing or axle sleeve, inclinator is provided with rotating disc and fixed disk, and described inclinator is a kind of device that action command that operating mechanism is passed over is converted to blade controlled motion. Described operating mechanism connects the fixed disk of inclinator, and small machine or electromagnetic energy in operating mechanism promote telescopic transmission shaft by inclinator, reaches screw displacement object thereby the expanding-contracting action back and forth of power transmission shaft drives blade to rotate.
The invention has the advantages that.
1, simple in structure, propeller hub is directly assemblied in and on rotor, has reduced transmission link.
So 2, improve the wind resistance of multiaxis gyroplane by improving the angle of attack energy moment grasp balance of motor speed and change screw.

Detailed description of the invention
Described variable-pitch propeller paddle mechanism is made up of with operating mechanism (7) etc. blade (1), blade root (2), propeller hub (3), pitch-change-link (5), power transmission shaft (4), inclinator (10), motor (6). Blade (1) is assemblied in propeller hub (3) above by blade root (2) and can be in the upper rotation of propeller hub (3), and described propeller hub (3) is directly assemblied on motor (6) rotor. Described power transmission shaft (4) one end is directly connected the rotating disc of inclinator (10) through motor (6) centre bore (8) by pitch-change-link (5) with by the root assembly connection other end or connects the rotating disc of inclinator (10) by control operating rod (11). When a described power transmission shaft (4) is handled N blade (1) displacement simultaneously, power transmission shaft (4) directly connects the rotating disc of inclinator (10) through motor (6) centre bore (8); When a power transmission shaft (4) is only handled a blade (1) displacement, power transmission shaft (4) is made as Hollow Transmission Shafts (4), due at least two blades of screw (1), thus N root power transmission shaft (4) and according to size intert be inserted in assembling after through motor (6) centre bore (8) by control operating rod (11) connect inclinator (10) rotating disc. It is that motor (6) shell, central shaft straight line whole process penetrate hollow design that described motor (6) is provided with centre bore (8), and described power transmission shaft (4) can inject the interior motor that also passes of central shaft of motor (6). Described inclinator (10) is exactly to make the power transmission shaft (4) of rotation become non-rotating state by bearing or axle sleeve, inclinator (10) is provided with rotating disc and fixed disk, and described inclinator (10) is a kind of device that action command that operating mechanism (7) is passed over is converted to blade (1) controlled motion. Described operating mechanism (7) connects the fixed disk of inclinator (10), it is flexible that small machine in operating mechanism (7) or electromagnetic energy promote power transmission shaft (4) by inclinator (10), power transmission shaft (4) thus expanding-contracting action back and forth drive blade (1) to rotate to reach screw displacement object.
