BAGHDAD - Part of quality preventative maintenance is looking for anything loose that shouldn't be and making the adjustment. On humvees specifically, the bolts to the four half-shafts, two in the ...

Solving insidious vibration problems in rotating equipment may sometimes seem like a black art that requires the right incantation. But identifying the root cause of the vibration is actually a ...

Because the causes of machine vibration are so numerous, the underlying problem is often difficult to isolate. Most troubleshooting processes rely on advanced diagnostic techniques and result in the ...

A new advance in vibration monitoring, developed with EPRI, facilitates the measurement of torsional vibration and is expected to be of significant value to power plants relying on a wide range of ...

Precision line shafts transmit torque across longer distances while maintaining mechanical synchronization. Here we review their basics, as well as speed considerations. Line shafts span long ...

Oil-whirl instability in rotor bearings was discovered by General Electric engineer Burt Newkirk in the 1920s. Since then, much has been written about design methods to reduce its harmful effects. Yet ...
