What is Gear Wheel Failure in Marine Thrusters about?

The document summarizes a failure analysis of two helical gear wheels from a marine azimuth thruster. The gear wheels both had broken teeth. Examination found fatigue fracture was the cause of damage. Scanning electron microscope analysis showed the gear teeth were under severe contact stress during operation, exacerbated by inappropriate lubrication. Misalignment between the pinions and gear wheels may also have contributed to premature failure. The broken teeth from both gear wheels showed similar fatigue
