(Summary description)Commonly used dynamic balancing machines contain a large number of rotating parts, such as various transmission shafts, main shafts, motors, steam turbine rotors, etc., collectively referred to as rotating bodies. Ideally, the pressure on the bearing is the same when the rotating body is rotating and not rotating, and such a rotating body is a balanced rotating body. However, due to various factors such as uneven materials or blank defects, processing and assembly errors, and even geometric asymmetry in the design.   The centrifugal inertial force generated by each tiny particle on the rotating body cannot cancel each other out. The centrifugal inertial force acts on the machine and its foundation through the bearing, causing vibration and noise, accelerating the wear of the bearing, and shortening the service life of the machine. In severe cases, it can cause Destructive accident. Therefore, it is necessary to balance the rotor to achieve the allowable level of balance accuracy, or reduce the amplitude of the mechanical vibration generated by it to the allowable range. The working principle and application characteristics of the dynamic balancing machine are: First, the motor is started to drive the tire to rotate. Due to the existence of the unbalance parameter, the centrifugal force exerted on the piezoelectric sensor in all directions of the tire is converted into an electrical signal. Through continuous measurement of the signal, the computer system analyzes the signal, and the display system calculates and displays the size of the imbalance and the position of the parameter. In order to meet the requirements of unbalance, that is, the sensors and analog-to-digital converters in the system must choose products with high sensitivity, high sensitivity, and high precision. At the same time, in order to ensure repeatability, the computer system must measure the electrical signal many times, so the calculation speed and test speed of the computer system are sufficiently high. The transmission mode of the dynamic balancing machine includes belt drive, coupling drive and self-drive.
