Abstract

The present invention provides a propeller synchronous pitch variable mechanism and its pitch variable propeller. The synchronous pitch variable mechanism includes: a drive shaft; The rods are evenly spaced on the periphery of the connecting portion, the connecting portion is connected to the drive shaft, and the driving shaft can drive the connecting portion to move up and down; at least three pitch-changing arms, each pitch-changing arm has a first end and a second end, and the pitch-changing arm has a first end and a second end. The second end of the second end is fixedly connected with the propeller blade; at least three linkages, at least three linkages are respectively provided in one-to-one correspondence with at least three extension rods and at least three pitch-changing arms, and the linkages are arranged on the extension rod and the pitch-changing arm Between the first ends of the arms, the star moves by driving the linkage to drive the pitch of the propeller blades. The technical solution of the present invention is applied to solve the technical problem that the propeller torque conversion structure in the prior art cannot realize synchronous and accurate torque conversion of multiple propeller blades, and the structure of the torque conversion structure is relatively complicated and the cost is high.

Description

Technical field [0001] The present invention relates to the field of aviation power technology, and more particularly to a propeller synchronous beaclope mechanism and a spasib propeller having it. Background technique [0002] The propeller is driven by rotating the air surrounding the air surrounding the blade, thereby meeting the power demand of the aircraft. At present, various types of aircraft with highly flying capabilities across large airspace are used to change the propeller driving force to meet the propeller driving force to meet different flight states. [0003] The propeller shift is a spiral screw surface to rotate the blade by a bezel mechanism to rotate its opposite hub. Each of the blades rotates to a position, there is a corresponding pitch angle to generate a corresponding driving force. After the propeller gap, its performance has changed, which can accommodate various sailing states to propeller requirements. For high-altitude low Renault aircraft, different...
