动平衡机原理与力学知识是分不开

动平衡机在很早就出现了,但平衡技术主要是在近四十年发展的。我国的平衡技术和装置是从五十年代开始开发的。从牛顿运动定律知道,任何物体在匀速旋转时,旋转体内各个质点,都有将产生离心惯性力,简称离心力,盘状转子,转子是以角速度 ω 作匀速转动,则转子体内任一质点都将产生离心力 F ,则离心力 F=mrω2, 这无数个离心力组成一个惯性力系作用在轴承上,形成转子对轴承的动压力,其大小则决定于转子质量的分布情况。如果转子的质量对转轴对称分布,则动压力为零,即各质量的离心力互相平衡。
Dynamic balancing machine appeared in a long time ago, but the balance technology is mainly developed in the past forty years. The balance technology and equipment in our country began in 50s. Know from Newton's laws of motion, any object in the uniform rotation of the rotating body, each particle, have the centrifugal force of inertia, referred to as centrifugal force, disc rotor, rotor with angular velocity of uniform rotation, the rotor body of any particle will produce centrifugal force F, from the heart of F=mr. 2. The numerous centrifugal inertial force system consisting of a role in the formation of dynamic pressure bearing, rotor bearing, the distribution depends on the quality of rotor. If the mass of the rotor is symmetrical to the rotor, the dynamic pressure is zero, that is, the centrifugal force of each mass is balanced.
否则将产生动压力,尤其在高速旋转时动压力是很大的。因此,对旋转体,特别是高速旋转体进行动平衡校正是必须的,这就是动平衡机的原理,与力学的知识是分不开的。我公司提供平衡机和动平衡机专业指导。
Otherwise, there will be a dynamic pressure, especially in the high-speed rotation of the dynamic pressure is very large. Therefore, it is necessary to adjust the balance of the rotating body, especially the high speed rotating body. Our company provides professional guidance for balancing machines and balancing machines.
