How a rotor balance is done?

If there is a problem during the use of the motor balancing machine, it will not only affect the normal use of the balancing machine, but also affect its measurement results, resulting in inaccurate measurement, and hindering the normal use of the product. In order to ensure that the balancing machine can operate accurately, we will do a good job in the daily maintenance of the balancing machine, and do a good job in the maintenance of the balancing machine to make the use of the balancing machine more smooth. The motor balancing machine is a sophisticated testing equipment, and a dedicated person must be responsible for storage and operation. In normal use, the balancer should be kept clean, the guide rail surface should be kept clean, and oil should be frequently applied to prevent rust. The surface of the support block or the roller should be kept clean, and no iron filings, dust and debris should be adhered. The support block or the roller and the rotor journal should be wiped clean before each work, and a little lubricating oil should be added. When moving the support frame, the rotor should be rotated at the same time or the left and right support frames should be moved at the same speed at the same time, so as to avoid scratches and wear on the shaft journal and roller surface. It is not allowed to put the rotor on the roller frame for knocking or impact.
The electric measuring box is a key part of the balancing machine. It must be protected from vibration and moisture and should be kept properly. Turn off the switch of the electrical test box after the work is completed. If it is not used for a long period of time, it should be regularly energized to warm up for several hours. All knobs and switches on the panel of the electrical measuring box shall not be moved at will, so as not to damage the components and cause measurement errors. The lens glass of the photoelectric head should always be wiped with lens cleaning paper or lens cloth to clean the outer surface of the lens to keep it clean. Do not wipe the lens surface with greasy yarn or dirty cloth. In terms of dynamic balance testing and correction technology, Jizhi has established a technical team led by professors from Zhejiang University, has mastered relevant core technologies, and has obtained nearly 100 intellectual property rights such as national patents and software copyrights. The main product, fully automatic balance correction machine, has been widely used in household appliances, power tools and auto parts.

Why does the rotor need to be dynamically balanced?

Because the unbalanced rotor undergoes dynamic balance correction, not only the even unbalance is eliminated, but also the static unbalance is eliminated. At this time, the central inertia principal axis of the rotor and the axis of rotation are exactly the same, so that the rotor reaches balance. However, the ideal is plump and the reality is skinny. It is impossible to balance an unbalanced rotor to zero. Because it is affected by the accuracy of the dynamic balancing equipment and the limitations of the rotor. Therefore, there is the concept of balance accuracy. The automatic rotor dynamic balancing machine developed by Jizhi can effectively solve the problem of “how to correct the rotor imbalance”. That is, under the existing conditions, we can reach a reasonable numerical magnitude, which not only meets the requirements of production and life, but also meets the

We all know that the motor rotor is divided into two types: inner rotor rotation and outer rotor rotation. The rotation mode of the inner rotor is that the core in the middle of the motor is a rotating body, which outputs torque (refers to electric motors) or receives energy (refers to generators). The rotation mode of the outer rotor means that the outer body of the motor is the rotating body, and different modes facilitate the application in various occasions.

Jizhi has been focusing on the research and development, production and sales of balancing technology and related products. The company has mastered the core technology in the balancing field and provides comprehensive solutions. At present, the company’s products cover application fields such as household appliances, automobile industry, aviation, shipbuilding, high-speed rail, and military industry.

How many categories of balancing machines?

Where there is rotation, there is balance. The center of mass of the rotating parts is shifted, and high-speed rotation will cause vibration and noise, leading to failures and accidents. Provide a comprehensive solution for balancing, which is what Jizhi Balance Machine has been doing. Since there are many different types of balancing machines, many people want to know what the specific classification of balancing machines is. Today, the editor of Jizhi balancing machines will share with you “How many types of balancing machines are divided into measurement principles? class”

Jizhi’s balancing machines are classified in principle into hard supporting balancing machines and soft supporting balancing machines. The hard bearing balancing machine is a balancing machine whose balancing speed is much lower than the resonance frequency of the vibration system. During balance verification, the supporting swing frame is relatively in a “hard” state, so the transfer can be used for balance correction under conditions close to the actual bearing; it has the characteristics of simple operation and good safety performance.

The soft support balancing machine is a balancing machine whose balancing speed is greater than the resonance frequency of the vibration system. During balance check, the supporting swing frame is relatively in a “soft” state, so when the rotor checks the balance. The supporting conditions are different from the actual bearing working conditions and have the characteristics of high measurement accuracy.

Because the characteristic of the soft support balancing machine is that the measuring speed is higher than the first-order resonance frequency of the measuring system, the vibration amplitude generated by the same unbalance is large, and it has the characteristics of high precision. At the same time, due to the characteristics of the soft support vibration system, it will interfere with external vibration. It is not very obvious, and the requirements for the working environment are low, so the automatic balancing machine is generally based on the soft support balancing machine. But its disadvantage is that it will pass through a resonance point when the speed is increased. It is very difficult and dangerous for a large rotor to pass the resonance point. Therefore, the measurement of a large rotor is mainly based on a hard-supported balancer.

The company has mastered the core technology in the balancing field and provides comprehensive solutions.
