Abstract

The invention relates to a tilting rotorcraft transmission system. The tilting rotorcraft transmission system comprises an engine output transmission unit, a pair of rotor speed reduction units symmetrically connected to the two sides of the engine output transmission unit, and a pair of tilting units symmetrically arranged on the two sides of the engine output transmission unit and connected with the rotor speed reduction units in a one-to-one correspondence mode. According to the transmission system, one engine is adopted for output, diversion is conducted through bevel gears, power is transmitted to the rotors on the two sides, concentrated transmission of power input in one direction and power output in two directions is achieved, the weight is greatly reduced, and the structural space is reduced; in addition, the tilting unit and the rotor wing speed reduction unit are placed in the same casing, the weight can be reduced, and the structural size can be reduced.

Description

Technical field [0001] The present invention belongs to the aerospace field, relates to a tilt rotorcraft transmission system. Background [0002] In aerospace aircraft, there are conventional helicopters and fixed-wing aircraft, helicopters can take off and land vertically, and hover in the air, but the flight speed is low; fixed-wing aircraft fly at a high speed, but take-off requires a longer runway. The tiltrotor combines the advantages of the above two models, which can not only fly at high speed, but also can take off and land vertically and hover in the air. In the three key moving parts of the tilting rotorcraft, the transmission system is one of the key moving parts, its main role is to drive the engine and other accessories to work, the mode of action is to transmit the engine power and speed to the two sides of the rotor and other accessories according to the specific transmission ratio, is an important transmission system for the power output of the tilting rotor eng...
