The invention discloses a variable-speed transmission system for a helicopter and the helicopter with the variable-speed transmission system. The variable-speed transmission system for the helicopter comprises a power source, a transmission mechanism and a transmission mechanism, the input end of the first differential mechanism is selectively in power connection with the output end of the power source; a main transmission mechanism and a side transmission mechanism, the output end of the main transmission mechanism is connected with a main rotor, the output end of the side transmission mechanism is connected with a propulsion propeller, and the output end of the first differential mechanism is selectively in power connection with the main transmission mechanism and the side transmission mechanism; and the hydraulic braking module is used for adjusting the driving force in the main transmission mechanism and/or the side transmission mechanism. According to the variable-speed transmission system for the helicopter, stepless speed regulation of the rotating speed of the main rotor wing and/or the rotating speed of the propelling propeller can be achieved according to needs, and decoupling between the rotating speeds of the main rotor wing and the propelling propeller is achieved.
