HZ-9702A Universal Joint Drive  Balancing Machine  uses universal joints to connect the main shaft of the balancing machine with the rotor. The characteristic of coupling drag is that it is suitable for rotors with irregular appearance, can transmit larger torque, and is suitable for dragging rotors with large wind resistance such as fans. The disadvantage of coupling drag is that the unbalance of the coupling itself will affect The rotor has an impact (so the coupling must be balanced before use), and interference will also be introduced to affect the accuracy of the balance. In addition, numerous connecting disks must be made to adapt to different types of rotors.


Dynamic Universal Joint Drive  Balancing Machine is mainly a hard-bearing balancing machine that combines high-precision mechanical parts and advanced electrical parts into one. This series of products is one of the universal universal joint drive balancing machines developed, designed and manufactured by our company based on the core technology at home and abroad. It is currently an internationally advanced model, which is applied to various rotating workpieces, such as centrifuge rotors, fan rotors, centrifugal impellers, large water pump rotors, generator rotors, internal combustion engines, dryers, screen baskets, crushers, crushers, Train wheel sets, steam turbines, agricultural machinery and other industries.
This Universal Joint Drive  Balancing Machine adopts universal joint transmission device, and the universal joint shaft can move in a small range without clearance to facilitate the connection between the workpiece and the universal joint. Its characteristics have the advantages of high precision, high efficiency, convenient operation, intuitive display, rapid measurement, stable performance, and the use of frequency conversion speed control device to control the speed.
The electromechanical measurement system can be equipped with a microcomputer digital display measurement system or a computer measurement system.

An unbalanced rotor generates a pressure on its supporting structure and the rotor itself during its rotation, and causes vibration. Therefore, the dynamic balance of the rotor is very necessary. The balancing machine is to check the dynamic balance of the rotor in the rotating state. The function of dynamic balance is:
● Improve the quality of the rotor and its components
● Reduce noise
● Reduce vibration
● Improve the trial life of supporting parts (bearings)
● Reduce user discomfort
● Reduce the power consumption of the product
