Rotating unbalance : ウィキペディア英語版 | Rotating unbalance
Rotating unbalance is the uneven distribution of mass around an axis of rotation. A rotating mass, or rotor, is said to be out of balance when its center of mass (inertia axis) is out of alignment with the center of rotation (geometric axis). Unbalance causes a moment which gives the rotor a wobbling movement characteristic of vibration of rotating structures. ==Effects of unbalance==
* Vibration * Noise * Decreased life of bearings * Unsafe work conditions * Reduced machine life * Increased maintenance
