Influence of Coexistence of Pitting and Cracking Faults on a Two-Stage Spur Gear System

This work considers forced vibrations in a rotating structure consisting of two-stage spur gear system with coexisting defects, specifically pitting and cracking. Numerical simulations experimental analysis various scenarios the operation were conducted using RPM–Frequency mapping technique. To identify fault characteristics, performed assumed had been misadjusted by combination cracking on teeth. The correlation system-forced responses under regular chaotic revealed that is far more sensitive to crack than when there are fluctuating harmonic peaks present at high vibration levels.
