一、动平衡试验机的测量原理机械设备中最常见的问题之一是旋转件的不平衡。这种不平衡常见于风扇,鼓风机和水泵的叶轮、飞轮、转子等等设备零部件中。由于转子的材质不均、毛坯缺陷、加工和装配误差等原因,使其质量不均匀,形成一定的偏心,当转子转动时就产生不平衡的离心惯性力,从而使机器产生有害的振动和噪声。旋转机械中的不平衡,导致设备的过份振动和某些力的产生,以致引起像轴承,联轴器等机件甚至旋转体本身过早地损坏。平衡就是为了减小不平衡离心力,使机器运转平稳的一种工艺方法。对于刚性旋转体,可以在两个校正平面上校正,常用的校正和 First, the principle of dynamic balance testing machine Mechanical equipment, one of the most common problems is the imbalance of rotating parts. This imbalance is common in fan, blower and pump impeller, flywheel, rotor and other equipment components. Due to the uneven material of the rotor, the blank defects, processing and assembly errors and other reasons, make it uneven quality, the formation of a certain eccentric, when the rotor rotates unbalanced centrifugal inertial force, so that the machine produces harmful vibration and noise . Imbalance in rotating machinery, resulting in excessive vibration of the equipment and the production of some of the forces, resulting in parts such as bearings, couplings and even the rotating body itself prematurely damaged. Balance is to reduce the unbalanced centrifugal force, so that the machine running smoothly a process. For rigid rotors, it is possible to calibrate on two calibration planes, commonly used for calibration and correction
