Abstract

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 and accurate prediction of the service life of the gear is realized, time is saved, the gear service life prediction efficiency is improved, an accurate data basis is provided for maintenance and replacement of the gear, and the gear service life prediction efficiency is improved. Therefore, safe operation of mechanical equipment provided with the gear is guaranteed.

Description

technical field [0001] The invention relates to the technical field of equipment fault diagnosis, in particular to a gear life prediction method and device, Background technique [0002] With the increasing complexity and maintenance cost of mechanical equipment, more and more attention has been paid to the fault diagnosis and condition monitoring technology of equipment components. Gears are one of the most commonly used and easily damaged parts in mechanical equipment. If the service life of gears When it expires, it will be prone to failure, which will affect the normal working state of mechanical equipment and cause mechanical equipment failure. [0003] Therefore, how to accurately predict the life of gears is of great significance to the safe operation of mechanical equipment and to ensure the working efficiency of mechanical equipment. However, in the existing technology, gear life prediction mainly relies on human observation of gear meshing and gear shape. The pred...
