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.

    本发明涉及一种带传动式倾转旋翼机传动系统,包括发动机输出换向单元、连接于发动机输出换向单元的中间换向减速单元、对称连接于中间换向减速单元两侧的一对倾转换向减速单元,以及对称布置在发动机输出换向单元两侧且与倾转换向减速单元一一对应连接的一对倾转作动单元。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,实现了将倾转作动单元与倾转换向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。
