Dynamic Balancing 정확도 등급

기계에서 축을 중심으로 회전하는 부분을 기계의 로터라고 합니다. 로터의 질량 분포가 균일하고 적절하게 제조 및 설치된 경우, 작동이 균형을 이룹니다.. 이상적인, 베어링에 가해지는 압력, 중력 이외, is the same as when the rotor is not rotating, with only static pressure.This rotor with only static pressure on the bearing when it rotates and does not rotate is called a balanced rotor. If the rotor has additional dynamic pressure to the bearing in addition to static pressure when it rotates, it is called an unbalanced rotor.

In fact, there is no absolute balanced rotor, while great vibration caused by big unbalance mass could do damage to the machines. 그러므로, dynamic balancing machine is widely applied to all industries, to reduce the unbalance weight to a reasonable balance accuracy grades. Rotors of different industries require different dynamic balance grades due to their features.

Here we list some dynamic balancing grade requirements for workpieces industries.
