The dynamic balancing machine is a high-precision measuring instrument. Most people just know but are not familiar with it, which leads to errors in purchasing the balancing machine. Therefore, we need to use some methods when purchasing the balancing machine so that we can use it. In order to facilitate and improve our work efficiency, the following small series will explain to you the purchase balancing machine what are the precautions?

1. We must first look at the measurement accuracy of the dynamic balancing machine to see if there is any error, because the error is very annoying when measuring, so the connection mode of the transmission shaft and the balancing machine and the machining axis accuracy of the main machine are one factor that affect the error.

2. The heavier the weight of the base, the better the quality of the base, and has no effect on the balance accuracy. But it mainly affects the weight loss rate. To achieve the same weight loss, you can use a bulky base or an optional base. -

3, using a soft support balance machine, the speed must reach more than 3 times the resonance speed to detect, so generally use a higher speed, and the hard support balance machine, the speed must be less than 3 times the resonance speed, so generally use Low speed.

4, dynamic balancing machine is divided into two types: soft support and hard support. Compared to the two, the soft bearing balancer swings relatively softly. During the start and stop of the drive shaft, the swing frame of the soft support will have very noticeable vibrations, and the swing frame of the hard support will not. Among the factors affecting the balance accuracy, soft support and hard support are just a negligible factor.

5, excellent computer software. For the balancing machine, the design is an important point of the measuring system. It can be known that the mechanical system design mainly considers the mechanical characteristics of the unbalanced vibration system, the supporting mode of the rotor, the driving method, and the conversion method of the mechanical vibration amount and the electric quantity, etc. The unbalanced amount of the rotor is turned into a signal signal through the sensor without distortion, and is tested by the measuring system. Due to the inevitable mechanical interference, in addition to the main vibration that the unbalance amount is expected when the actual pendulum vibrates, the interference vibration is also included. Because it is in the case of small imbalance, this kind of disordered interference is stronger than the main signal. Therefore, these powerful interference signals will measure the weak unbalanced signals, so the designed measurement system also needs to have excellent frequency selection. Filter performance.
