Embodiment Construction

[0035] A mechanical synchronizer of the present invention comprises a synchronizer box 16, at least two transmission shafts 3 connected to the synchronizer box 16 at one end, and the other end of the transmission shaft 3 is connected to the propeller power input shaft 7;

[0036] The synchronizer case 16 includes at least one direction changing mechanism, which can synchronously change the power of the power input shaft of the synchronizer case 16 to the at least two transmission shafts 3;

[0037] The at least two transmission shafts 3 are hyperbolic reduced-diameter transmission shafts 3;

[0038] The end of the transmission shaft 3 connected to the propeller power input shaft 7 also includes at least a direction changing mechanism, which can change the power of at least two transmission shafts 3 to the propeller power input shaft 7;

[0039] The propeller power input shaft 7 is connected to a transmission mechanism housing 14 through a support bearing sleeved on the propell...

Abstract

A mechanical synchronizer of that invention relates to the field of aircraft component, in particular to the field of multi-rotor unmanned aerial vehicles (UAVs), in particular to a mechanical synchronizer, comprise a synchronizer housing, at least two transmission shafts with one end connected to the synchronizer housing, and the other end of the transmission shaft is connected to a propeller power input shaft; The synchronizer housing at least comprises a redirecting mechanism capable of synchronously redirecting the power of the power input shaft of the synchronizer housing to the at leasttwo transmission shafts; The at least two transmission shafts are hyperbolic variable diameter transmission shafts; The invention has the advantages of simple structure, convenient use, low manufacturing cost, simple transmission, safety and reliability, and realizes the synchronous change direction transmission of the power transmission direction by using the change direction mechanism arranged in the synchronizer box, thereby realizing the synchronous operation of the propeller.

Description

technical field [0001] The invention relates to the field of aircraft parts, in particular to the field of multi-rotor unmanned aerial vehicles, and in particular to a mechanical synchronizer. Background technique [0002] Aircraft such as the "Chinook", "Kaman" and "Osprey" V-22 of the United States have high efficiency, large load, flexible maneuverability, reliable performance, and a wide range of applications. [0003] The United States uses their advanced electronic products to control the engine to realize the two engines running at the same speed. It is a method of using electronic technology to control the propeller speed and blade angle (variable pitch and speed) to control the aircraft. This method requires high technical level of electronic products (such as: anti-interference, high reliability, high sensitivity, etc.) , high manufacturing cost, high maintenance cost, high failure rate, and many safety hazards. For this reason, a rotorcraft synchronizer with saf...
