Abstract
Background: Bearings are a kind of precision mechanical basic parts that are widely used in aerospace, automobile, home appliances and industrial fields. At the same time, bearings are also one of the most important wear parts in mechanical equipment. The research and analysis of bearing life are of great significance as they directly affect the efficiency and safety of the equipment.
Objective: By analyzing and discussing the patents on bearing life testing devices, some valuable conclusions have been drawn, and the development direction of bearing life research and bearing testing devices is speculated.
Methods: Various bearing life testing devices, such as life testing machines, performance testing machines and simulation testing machines, are observed, and the influence of bearing life testing devices on bearing quality assessment and product development is analyzed. The patents about the bearing life testing device are investigated in conjunction with the bearing life data signal acquisition method.
Results: The analysis of bearing life detection devices in bearing fatigue life and performance failure in the bearing failure detection collection method primarily uses vibration detection method, while bearing life detection devices primarily focus on structural innovation and detection method innovation to improve the accuracy of bearing detection.
Conclusion: The development of the bearing detection device and the advancement of test software, multi-species, small batch, high precision, multiple control, group control, simulation of working conditions, and special development work in tandem to address technical issues and improve bearing detection device functionality.
