Abstract

The invention relates to a high-speed helicopter transmission system, which belongs to the field of space flight and aviation, comprises a main rotor transmission subsystem and a propeller transmission subsystem, adopts a pure bevel gear train in structure, and consists of a propeller horizontal reversing bevel gear pair, a main rotor vertical reversing bevel gear pair and a two-wing horizontal reversing bevel gear pair. Power is input through a helicopter main reduction shaft. Power is transmitted through two paths to drive the main rotor and the two-wing propellers respectively, wherein onepath is transmitted from the main reduction shaft to the propeller horizontal reversing bevel gear pair and the two-wing propeller bevel gear pair and then horizontally reverses through the two-wing propeller bevel gear pair to drive the propeller, and the other path is transmitted from the main reduction shaft to the main rotor vertical reversing bevel gear pair and then drives the main rotor torealize power output. While two functions of driving the main rotor wing by vertical reversing of power and driving the propeller by horizontal reversing are realized, the structure is compact, the weight is light, the transmission efficiency is high, the stability is good, the stable driving capability is realized, and the medium-high speed transmission is realized.

Description

technical field [0001] The invention belongs to the field of aerospace and aviation, and relates to a transmission system for transmitting and distributing engine power to main rotors and propellers. Background technique [0002] The transmission system is one of the three key moving parts of the high-speed helicopter. Its main function is to drive the engine accessories and aircraft accessories to work, and transmit the power and speed of the engine to the main rotor, propeller and other accessories of the high-speed helicopter according to a certain transmission ratio. It is an indispensable power transmission component for the power output of the helicopter engine. The performance of the transmission system largely determines the working performance and reliability of the entire helicopter. Because of the special work requirements of the helicopter, there are stricter requirements on its transmission system. Under the premise of realizing the functional requirements of h...
