The widely used balancing machine measurement methods in the market mainly include ring belt drive, self drive, universal joint drive, etc. So, what are the advantages and disadvantages of different driving methods for balancing machines? The technical master of Huake Zhichuang Dynamic Balancing Machine will explain in detail for everyone.
Belt balancing machine
Ring and belt balancing machine: Ring and belt drive is a high-precision driving method for balancing machines, which measures the rotation of the rotor through the rubber or silk woven ring belt of the balancing machine and is driven by the motor pulley. Therefore, the ring and belt balancing machine requires a smooth cylindrical surface to be measured on the surface of the rotor. If the surface is not smooth or has irregular shapes, the loop belt transmission method cannot be successful.
The advantages of coil drive: it does not affect the measurement of rotor imbalance, has high dynamic balance accuracy, and is easy to operate.
Disadvantage of ring drive: The measuring rotor must have a smooth cylindrical surface.
Self driving balancing machine
Self driving balancing machine: Self driving technology utilizes the power of the rotor itself to rotate. Self driving is the driving method that has the least impact on balance accuracy, and the balance accuracy can reach the highest. However, only special rotors with structural permission can use this driving method.
The advantages of self driving: simulating actual operating conditions for measurement, high balance accuracy, and eliminating secondary balance errors caused by component assembly.
Disadvantage of self driving: Only special workpieces with allowable structure can use this driving method.
Universal joint balancing machine
Universal joint balancing machine: the principle of universal joint drive is that the balancing machine is connected with the rotor through the main shaft, which can transmit greater torque. It is suitable for driving rotors with large wind resistance such as fan impellers, but because the imbalance of the universal joint itself will affect the measuring rotor and interfere with the balance accuracy (so the universal joint should be balanced and corrected before use), in addition, a large number of connecting discs should be made to adapt to rotors of different models.
Dynamic advantages of universal joint drive: it is suitable for rotors with irregular appearance and has large transmission torque.
Disadvantages of universal joint drive: the imbalance of the universal joint itself will affect the rotor balance and interfere with the balance accuracy. In addition, a large number of connecting discs will be made to adapt to different types of rotors, and the measurement accuracy is low.
Balancing machines are essential equipment for reducing vibration, improving performance, and improving quality. Each unbalanced rotor generates a pressure on its supporting structure and the rotor itself during its rotation, leading to vibration. The dynamic balance of the rotor is very necessary, and the Huake Zhichuang balance machine is a test of the dynamic balance of the rotor in a rotating state; The main performance of a dynamic balancing machine is to use two comprehensive indicators: the minimum achievable residual imbalance, and the reduction rate of the dynamic balancing machine
