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 casi
