What are the causes for the failure of shafts

Shaft failures do not happen everyday but when they do it can be a challenge to determine the cause of failure Here s a technical explanation of what happens when the shaft bends or breaks 1 Transverse Vibrations 2 Torsional Vibrations 3...

Propulsion Shaft Failures

May 04 2010 0183 32 Operation in bad weather causes propeller loading to vary widely as the stern plunges deeper then partially rotates in air Shaft bending may take place as a result of ship hull deformation More importantly is the unusually high torque loading when changing propeller rotation going ahead or astern in some cases the torque may be doubled...
