Dynamatic Balance Machine- Single-sided Vertical De-weighting Balancing Machine
Application
It is mainly composed of high-precision mechanical parts and advanced electrical parts, a combination of hard-supported balancing machines. This series of products is one of the single-sided vertical weight-removing balancing machines developed, designed and manufactured by our company based on core technologies at home and abroad. It is currently the most advanced model in the world and is used in various disc workpieces, such as: brake discs, clutches, brake drums, water pump impellers, flywheels, gears, pulleys, flanges, fan impellers, saw blades, tools , Balance detection and correction of parts such as grinding wheels, traction wheels, lathe chucks, etc.,
This machine is equipped with special clamps and de-weighting device, which is convenient for clamping, which improves the work efficiency for users. It is characterized by high precision, high efficiency, convenient operation, intuitive display, rapid measurement, stable performance, and the speed is controlled by a frequency conversion speed control device and other advantages.
The electromechanical measurement system can be equipped with a microcomputer digital display measurement system or a computer measurement system.
Features
1.The professionally designed swing frame can effectively transmit mechanical force, is sturdy and reliable, has low vibration resistance and good rigidity;
2.High sensitivity sensor, good linearity, durable and reliable;
3. Permanent calibration measurement principle, high accuracy, allowing extremely high initial imbalance;
4. Equipped with special fixtures, with higher accuracy and easier clamping;
5. Advanced electrical measurement system, friendly man-machine interface, complete functions
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.
