Summary:The invention provides a gear service life prediction method and device. The method comprises the following steps: acquiring a historical vibration acquisition signal and a current moment of a target gear; calculating a characteristic signal of the target gear based on the historical vibration acquisition signal; inputting the characteristic signal into a preset time and characteristic signal relation model, carrying out model training, and determining model parameters of the preset time and characteristic signal relation model; and generating a gear life prediction result of the target gear based on the failure characteristic signal corresponding to the failure of the preset gear, the trained preset time and characteristic signal relation model and the current moment. Therefore, the service life condition of the gear is predicted in real time by using the vibration acquisition signal and the failure characteristic signal of the target gear, so that manual experience does not need to be relied on, automatic a
