The invention relates to a transmission system of a light unmanned helicopter. The transmission system comprises a main speed reducer, a tail speed reducer and a middle transmission shaft system, wherein the main speed reducer comprises a high-speed shaft, an intermediate shaft and a rotor shaft; the high-speed shaft and the intermediate shaft are parallel with each other and are in meshed transmission through a pair of high-speed gears; the intermediate shaft and the rotor shaft are perpendicular to each other and are in meshed transmission through a pair of low-speed bevel gears; the tail speed reducer comprises a tail reducing input shaft and a tail rotor shaft which are perpendicular to each other and are in meshed transmission through a pair of bevel gears; the high-speed shaft and the tail reducing input shaft are connected through an intermediate transmission shaft system; the intermediate transmission shaft system comprises a coupling and a pipe shaft; the main speed reducer realizes power transfer and distribution, transfers the low speed to the rotor shaft through the pair of low-speed bevel gears and transfers the high speed to the tail rotor shaft through the intermediate transmission shaft system. The transmission system is simple and reasonable in structural design and convenient to mount and maintain and has the certain significance in design and improvement of transmission systems of military light unmanned helicopters.
