动平衡机是衡量平衡效率的指标

一个不平衡的转子在其旋转过程中对其支承结构和转子本身产生一个压力,并导致振动。因此,对转子的动平衡机是十分必须的,平衡机就是对转子在旋转状态下进行动平衡较验。动平衡的作用有:
An unbalanced rotor creates a pressure on the supporting structure and the rotor itself during its rotation and causes vibration. Therefore, the dynamic balance of the rotor is very necessary, balancing machine is the rotor in the rotating state of balance. The role of dynamic balance:
1、提高转子及其构成的产品质量;减小噪声;
1, improve the quality of the rotor and its products;
2、减小振动。
2, reduce vibration.
3、提高支承部件(轴承)的使用寿命。
3, improve the supporting parts (bearings) service life.
4、降低使用者的不舒适感。
4, reduce the user's sense of discomfort.
5、降低产品的功耗。
5, reduce the power consumption of the product.
平衡机的主要性能是用最小可达剩余不平衡量,和不平衡量减少率两项综合指标表示的。前者是平衡机能使转子达到的剩余不平衡量的最小值,它是衡量平衡机最高平衡能力的指标;后者是经过一次校正后所减少的不平衡量与初始不平衡量之比,动平衡机是衡量平衡效率的指标,一般用百分数表示。
The main performance of the balancing machine is to use the minimum achievable residual unbalance, and the imbalance of the reduction rate of two indicators. The former is the minimum balance function of the rotor to the residual unbalance, it is a measure of the highest balance machine balance index; the latter is reduced after a correction after the unbalance and initial unbalance ratio, it is a measure of the balance of efficiency index, typically expressed in percentages.
