Vibration feature of spur gear transmission with non-uniform depth distribution of tooth root crack along tooth width

Jieyu Ning et al.

Summary: Gear tooth root crack is a typical fault in gear transmissions that poses a threat to operational safety. Detecting and understanding the severity of these cracks is crucial for preventing accidents. This study introduces an improved gear dynamics model to accurately model non-uniform distribution of tooth root cracks and their impact on vibration characteristics, providing important insights for quantitative detection and diagnosis of such faults.
