The invention discloses a single-rotor unmanned helicopter rotating machinery fault simulation experiment table with a tail rotor, the whole experiment table adopts a combined installation mode, the lower end of the experiment table is provided with trundles and a rubber pad, and the upper end of the experiment table bears a servo motor, a torque sensor, an eddy current brake, a reduction gearbox and the tail rotor. The servo motor and the disc torque sensor are directly connected and vertically installed, the synchronous wheel is installed above the sensor and connected with an input shaft of the reduction gearbox through the synchronous belt, the disc torque sensor is installed above an output shaft of the eddy current brake, and the synchronous wheel is arranged on the other side of the sensor and connected with a main paddle of the reduction gearbox through the synchronous belt. A reduction gearbox tail rotor output shaft is connected with a micro-range dynamic torque sensor in series through a coupler, a synchronous wheel is arranged at the shaft end of the sensor, and a synchronous belt drives a tail rotor to rotate. The experiment table can simulate the faults of insufficient lubrication, over lubrication, lubrication pollution, damage and the like of a rotating machine of a main paddle reduction gearbox and a tail paddle under different rotating speeds and loads, the real machine test cost is reduced, and the fault detection efficiency is improved.
