The utility model discloses a thermal bending fault experiment device applied to a rotary machine, belongs to the technical field of rotor thermal bending fault experiments, and aims to solve the problem that a traditional experiment device cannot simulate a rotor system thermal bending fault experiment. The output end of the motor is connected with the input end of the gear box; the output end ofthe gearbox is connected with one end of the rotating shaft; wherein two ends of the rotating shaft are supported by sliding bearings, the rotor is arranged on the rotating shaft, a heating device matched with the rotor in shape is arranged outside the rotor, eddy current displacement sensor groups are arranged on one sides, close to the rotor, of the two sliding bearings, and the eddy current displacement sensor groups are used for measuring displacement of the rotating shaft or the rotor. The thermal bending fault experiment device applied to the rotary machine can simulate thermal expansion of the rotor and therma
