对于高速旋转的零部件,由于材质不均、加工装配误差等原因转动零部件实际重心对旋转轴心总是有偏移的,在高速下旋转时将产生很大的离心惯性力,因而引起振动,在运动中产生附加的动压力。这不仅将增大运动中的摩擦和构件中的内应力,降低机器的效率和使用寿命,使之工作不可靠,而且这些惯性力都将传到机器的基础上,特别是惯性力大小及方向一般都是周期性变化的,这就必将引起机器及其基础产生强迫振动。因此使用动平衡机进行校正是非常有必要的。

For high-speed rotating parts, due to uneven material processing and assembly error to cause actual gravity rotating parts always offset on the axis of rotation, in high speed rotation will produce centrifugal force greatly, thus causing vibration, dynamic pressure force added in movement. This will not only increase the internal stress and friction component moving in, reduce the machine efficiency and service life, the work is not reliable, but the inertia force will pass to the machine, especially the size and direction of the inertial force is generally cyclical changes, which will cause the machine and its foundation forced to vibrate. Therefore, it is necessary to use the dynamic balancing machine for correction.
如果振动的振幅较大或者其频率接近共振范围就会带来不良后果。所以对高速旋转的零部件必须使用动平衡机进行动平衡以排除旋转零部件上的动不平衡的因素。
If the amplitude of the vibration is large or the frequency is close to the resonance range, it will bring bad results. Therefore, the high-speed rotating parts must be used to balance the dynamic balancing machine to eliminate the dynamic imbalance of rotating parts.
旋转零部件的动平衡工作是在动平衡机上进行的。随着科学技术的发展工艺水平的提高,出现了多种动平衡机,如闪光式动平衡机、瓦特计式动平衡硬支承动平衡机、激光动平衡机等。
The dynamic balancing of rotating parts is carried out on the dynamic balancing machine. With the development of science and technology, there are a variety of dynamic balancing machines, such as flash type dynamic balancing machine, Watt gauge type dynamic balance hard bearing dynamic balancing machine, laser dynamic balancing machine and so on.
动平衡机的作用是:
The role of dynamic balancing machine:
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;
