Dynamic balancing machine (DBM) 動平衡機
 It refers to the instrument used to measure the imbalance of the rotor. The balancer is a hard-supported balancer. The rigidity of the pendulum is very large. Use the measurement results of the dynamic balancer to correct the amount of imbalance in the rotor to make the rotor vibrate or act on the bearing Reduce the vibration to the allowable range to achieve the purpose of reducing vibration, improving performance and improving product quality.

 Measuring system 測量系統
 總 A general term for computer control software and related components used in dynamic balancing machines.

 Transmission system 傳動系統
 總 A general term for the computer control software and related components used in the dynamic balancing machine drive system.

 Automatic positioning 自動定位
 之一 One of the main characteristics of intelligent dynamic balancing machine.

 System capacity 系統能力
 The maximum measurement capacity that the automatic balancer system can achieve in unit time.

 Support method 支承方式
 In the dynamic balancer system, it is a general term for supporting equipment such as rotor rotation.

 Unbalance Amount of Unbalance 不平衡量
 The magnitude of the amount of imbalance on a plane of the rotor in the automatic balancing machine does not involve the angular position of the imbalance. It is equivalent to the product of the unbalanced mass and its center of mass to the rotor axis. The unit of the unbalanced quantity is gmm or gcm, commonly known as the "diameter product".

 Unbalanced position Angle of Unbalance 不平衡位置
 The angle value of the unbalanced mass on a plane when the workpiece is stopped by the automatic balancing machine relative to the given polar coordinates.

 Imbalance Eper 不平衡度
 The unbalance amount of the unit mass of the rotor, the unit is gmm / kg. In static imbalance, it is equivalent to the mass eccentricity of the rotor, and the unit is μm.


 Raw imbalance 原始不平衡量
 Auto balance corrects the amount of imbalance on the rotor before it is corrected.

 Allowed imbalance 允許不平衡量
 剩余 The remaining unbalance of the rotor allowed to confirm the normal operation of the rotating machine. When this indicator is expressed in imbalance, it is called the allowable imbalance amount.

 Residual imbalance 剩余不平衡量
 The amount of unbalance remaining after the rotor dynamic balance is corrected.

 Correction Radius 校正半徑
 的 The distance from the center of mass of the calibration mass to the rotor axis on the calibration plane is generally expressed in mm.

 Calibration plane interference (interaction) 校正平面的干擾
 變化 A change in the amount of imbalance on a given correction surface of a given rotor causes a change in the indication value of the balancer on another correction plane (sometimes called the plane separation effect)

 Rotor balance quality 轉子平衡品質
 An index to measure the balance of the rotor. Zh
 G = eperω / 1000
 In the formula, G is the balance quality of the rotor, and the unit is mm / s. There are 11 levels from G0.4 to G4000. Zh
 Eper－ Allowable unbalance rate of rotor gmm / kg or rotor mass eccentricity μm
 Ω－Angle speed corresponding to the maximum working speed of the rotor = 2πn / 60≈n / 10, n is the working speed of the rotor r / min
 
 的 Allowable imbalance of unit mass of rotor
 Eper = G × 1000 / n / 10 Unit: gmm / kg or μm

 Minimum achievable residual unbalance 轉子單位質量的允許不平衡度
 Minimum reachable residual imbalance (Umar). The unit is gmm. Its meaning refers to the minimum value of the residual imbalance that the rotor can reach by the balancing function. It is a performance index to measure the highest balancing ability of the balancing machine. When this indicator is expressed by the degree of imbalance, it is called the minimum achievable residual imbalance (codename: Emar, namely minimum achievable residual unbalance) (unit: gmm / kg)

 URUnbalance reduction ratio (URR) 不平衡量減少率
 比 The ratio of the amount of imbalance reduced to the initial amount of imbalance after a balance correction. It is a performance indicator to measure the efficiency of the balancing machine, expressed as a percentage:
 URR (%) = (U1-U2) / U1 = (1-U2 / U1) × 100
 In formula: U1-initial imbalance amount
 U2－Remaining imbalance after one balance correction

 Unbalanced force-to-interference ratio 不平衡力偶干擾比
 Single-sided balance machine suppresses the performance index of unbalanced force couple. Zh
 The unbalance amount of the unit mass of the rotor, the unit is gmm / kg. In static imbalance, it is equivalent to the mass eccentricity of the rotor, and the unit is μm.
