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.

    本发明涉及一种倾转旋翼机传动系统,包括发动机输出传动单元、对称连接于发动机输出传动单元两侧的一对旋翼减速单元,以及对称布置在发动机输出传动单元两侧且与旋翼减速单元一一对应连接的一对倾转单元。该传动系统采用一个发动机输出,通过锥齿轮进行分流,将动力传输到两侧旋翼,实现集中传动一个方向动力输入,两个方向动力输出,极大地降低了重量,减小了结构空间;此外,实现了将倾转单元与旋翼减速单元安放在一个机匣内,同样可以降低重量,减小结构尺寸。
