The utility model discloses a fault detection device for a gearbox. The fault detection device comprises an information acquisition module, an information transmission module and a central processor. The information acquisition module comprises a vibration sensor, a noise sensor and an eddy current sensor; the vibration sensor is used for collecting vibration data of the gearbox; the noise sensor is used for collecting noise data of the gearbox; detection probes of the eddy current sensor are located in the axial direction and the radial direction of an input shaft and an output shaft of the gearbox and used for detecting the axial displacement and the radial displacement of the input shaft and the output shaft. And the information transmission module is used for transmitting the collected vibration data, noise data and displacement data to the central processing unit. The fault detection device provided by the utility model can detect the gearbox more accurately, so that problems existing in the gearbox can
