INTRODUCTION: Gear transmissions of heavy-duty drive reducers operate under variable loads that cause fatigue damage (pitting and tooth fracture), therefore effective condition monitoring is essential to prevent failures..
OBJECTIVES: To conduct a review of the directions and methods for monitoring the technical condition of gearbox gears, to select an appropriate monitoring approach for the gears of high-power machine drives, and to propose the most effective method taking into account operating conditions and gear tooth control zones.
METHODS: The research employs an instrumental monitoring approach based on measuring the surface hardness of gear teeth using portable hardness testers. The methodology involves comparative analysis of metal hardness in two critical zones: the tooth end faces and the working surfaces.
RESULTS: Based on the conducted review, a method for monitoring the technical condition of gearbox gears in high-power drives has been developed. This method can be applied both in workshop and field operating conditions, enabling inspection of the working and non-working tooth surfaces with or without gearbox disassembly.
CONCLUSION: The developed monitoring method for gearbox gears of high-power drives will serve as a foundation for the development of a method for predicting the remaining service life of gearbox gears in high-power machine drives
