What are the factors that affect the accuracy of rotor dynamic balance detection? Due to the adoption of microcomputer technology by all dynamic balancing machine manufacturers, and the maturity of microcomputer dynamic balancing detection technology, the errors generated by electronic measurement are minimal. The accuracy of transmission shaft balancing machines is closely related to the electronic components.
The performance of dynamic balancing machines is basically independent of the display method, but digital display is not only intuitive, but also has the highest reliability and is not easily damaged. It can also provide some practical additional functions, so digital display is the mainstream direction. The wattmeter display method will gradually withdraw from the market. There are also balancing machines that use computer monitors, and their only advantage is that they appear more stylish and suitable for large users. However, their complexity is many times higher, so their reliability will be greatly reduced (the more complex things are, the more likely they are to malfunction). Small users should avoid using them.
When purchasing a dynamic balancing machine, pay attention to the following two points. Basically, you can find a suitable rotor for yourself and buy a satisfactory dynamic balancing machine without wasting too much money.
1. The connection method between the transmission shaft and the balancing machine.
2. Balancing machine spindle machining accuracy.
There are two types of dynamic balancing machines: soft support and hard support. Compared to the two, the swing of the soft support balancing machine is relatively soft. During the process of starting and stopping the transmission shaft, there will be very obvious vibration in the soft supported pendulum, while there is no such phenomenon in the hard supported pendulum.
In theory, soft support balancing machines can achieve higher testing accuracy; However, this can only be distinguished in extremely precise testing. For transmission shaft balancing machines, the accuracy that hard supports can achieve far exceeds actual needs. If it is found that the accuracy of a transmission shaft balancing machine cannot meet the requirements, it must be the result of other factors. Among the factors that affect balance accuracy, soft and hard support are just insignificant factors.
