The working principle and application of high-speed dynamic balancing machine

A high-speed balancing machine is an instrument and equipment used to measure rotor imbalance. It is calibrated based on its measurement results to improve the mass distribution of the balanced rotor and reduce the vibration of the shaft neck or the force acting on the bearings during rotor operation to a specified range.

Correcting the unbalance of the rotor based on the data measured by the balancing machine can improve the mass distribution of the rotor relative to the axis, reducing the vibration generated during rotor rotation or the vibration force acting on the bearings to within the allowable range. Therefore, a balancing machine is an essential equipment for reducing vibration, improving performance, and enhancing quality.

The balancing of a general rotor includes two steps: measuring and correcting the unbalance. A balancing machine is mainly used for measuring the unbalance, while the correction of the unbalance is often done with the help of other auxiliary equipment such as drilling machines, milling machines, and spot welding machines, or by manual methods. The calibration device has become an important part of the balancing machine.
