The invention relates to the technical field of helicopter parts, in particular to a speed reducer for a helicopter, which comprises a speed reducer body, an engine gear shaft, a main rotor shaft and a tail rotor gear shaft, the engine gear shaft is arranged on the left side of the speed reducer body, and the end, extending into the speed reducer body, of the engine gear shaft is connected with an engine driving gear. The main rotor shaft is arranged at the top of the speed reducer body, and the end, extending into the speed reducer body, of the main rotor shaft is connected with a main transmission gear; the tail rotor gear shaft is arranged on the right side of the speed reducer body, and the end, extending into the speed reducer body, of the tail rotor gear shaft is connected with an empennage driving gear. One side of the main transmission gear is meshed with the engine driving gear, and the other side of the main transmission gear is meshed with the empennage driving gear. The speed reducer for the helicopter is more compact in structure, and the transmission efficiency of speed reduction is improved.
