The invention belongs to the technical field of helicopter rotor tests, and particularly relates to an auxiliary disc paddle mechanism of a rotor test bed, which comprises a low-power power system, a gear transmission system, a fixed limiting assembly and a power output assembly, the low-power power system provides low-power low-rotating-speed power, the low-power low-rotating-speed power is transmitted to the power output assembly after being increased by a certain torque through the gear transmission system, and the power output assembly drives the rotor wing system to move. The gear transmission system is adjusted through the fixing and limiting assembly so as to achieve switching of test states of the rotor system. The auxiliary disc paddle mechanism realizes large-torque output and small-angle rotation by utilizing a small-power motor, a large-reduction-ratio speed reducer and a gear pair. The disc paddle mechanism motor and the main driving motor of the test bench are interlocked, so that the conversion of two input powers is realized.
