Abstract

The invention relates to a belt transmission type tilt rotorcraft transmission system which comprises an engine output reversing unit, a middle reversing speed reduction unit connected to the engine output reversing unit and a pair of tilt reversing speed reduction units symmetrically connected to the two sides of the middle reversing speed reduction unit. The tilting actuation units are symmetrically arranged on the two sides of the engine output reversing unit and connected with the tilting reversing 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 actuation unit and the tilting reversing speed reduction unit are placed in the same casing, the weight can be reduced, and the structural size can be reduced as well.

Description

technical field [0001] The invention belongs to the field of aerospace and relates to a transmission system of a belt-driven tilt rotor aircraft. Background technique [0002] Among aerospace vehicles, helicopters and fixed-wing aircraft are conventional. Helicopters can take off and land vertically and hover in the air, but their flight speeds are low; fixed-wing aircraft have high flight speeds but require a longer runway for takeoff. The tilt rotor aircraft combines the advantages of the above two models, which can not only fly at high speed, but also take off and land vertically and hover in the air. Among the three key moving parts of the tilting rotorcraft, the transmission system is one of the key moving parts. Its main function is to drive the engine and other accessories to work. As well as other accessories, it is an important transmission system for the power output of the tiltrotor engine. In the working performance and reliability of the tilting rotorcraft, th...
