Dynamatic Balance Machine-Universal Joint Type 30-100kg Metal Drive Shaft Balancing Machine
Driveshaft Dynamic Balancing Machine Overview
The balancing machine is an instrument used to determine the unbalance of the rotor. The balancing machine is a hard-supported balancing machine. The swing frame is very rigid. The measurement result of the dynamic balancing machine is used to correct the unbalance of the rotor, so that the vibration generated when the rotor rotates or acts on The vibration on the bearing is reduced to the allowable range to achieve the purpose of reducing vibration, improving performance and improving product quality.
Drive Shaft Balancing Machine is mainly used for the balance correction of the cross flow fan of the air conditioner and other similar rotating parts.
Driveshaft Dynamic Balancing Machine Application
It is mainly composed of high-precision mechanical parts and advanced electrical parts, combined into one hard-bearing balancing machine. This series of products is a special balancing machine developed, designed and manufactured by our company based on the core technology at home and abroad.Mainly used in automobile transmission shaft production and repair manufacturers, it has the characteristics of convenient operation, high balance accuracy, and low investment cost. It is an ideal equipment for the dynamic balance detection of automobile transmission shafts.
This electromechanical measurement system can be equipped with a microcomputer digital display test, or it can be equipped with a computer measurement, which can be configured according to the actual needs of the user.

Driveshaft Dynamic Balancing Machine Purpose
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
Unbalance amount calculation
Where mper is the allowable unbalance:
M: represents the weight of the rotor, the unit is kg
G: represents the balance accuracy grade of the rotor, the unit is mm/s
r : represents the correction radius of the rotor, the unit is mm
n: represents the speed of the rotor, the unit is rpm.
