The principle of the balancing machine

A balancing machine is an instrument used to determine rotor imbalance, and its working principle is mainly based on the centrifugal force generated by the rotating object (rotor) as it rotates around its axis due to the uneven distribution of mass relative to the axis. This unbalanced centrifugal force acting on the rotor bearing can cause vibration, produce noise, and accelerate bearing wear, seriously affecting the performance and life of the product.

The working principle of the balancing machine can be elaborated as follows:

1. The generation and impact of unbalanced

When the rotor is rotating, if its mass is not evenly distributed, an unbalanced centrifugal force is generated. This centrifugal force causes the rotor to vibrate during rotation, which in turn puts pressure on the supporting structure and the rotor itself. This vibration not only produces noise, but also accelerates bearing wear and tear, reducing the performance and life of the product.

Second, the role and principle of the balancing machine

The main function of the balancing machine is to measure the size and position of the rotor unbalance, and to correct the rotor unbalance according to the measurement results. By calibrating, the mass distribution of the rotor relative to the axis can be improved, so that the vibrations generated when the rotor rotates or the vibration forces acting on the bearing are reduced to the permissible range.

The working principle of a balancing machine mainly relies on the sensors and measuring systems inside it. When the rotor rotates on the balancing machine, the sensor detects supporting vibrations or vibrating forces caused by unbalanced centrifugal forces. These signals are then processed and analyzed by the measuring system to determine the magnitude and position of the rotor unbalance.

3. Types and characteristics of balancing machines

Balancing machines can be divided into various types according to different measuring principles and structural characteristics. Among them, gravity balancing machine and centrifugal force balancing machine are two typical types of balancing machines.

1. Gravity balancing machine: Rely on the gravitational action of the rotor itself to measure the static unbalance. It is usually placed on two horizontal rails, and if the rotor is unbalanced, the gravitational moment on the axis causes the rotor to roll on the guide rail until the unbalance is at its lowest.
2. Centrifugal force balancing machine: In the state of rotor rotation, the unbalance is measured according to the support vibration caused by the rotor unbalance or the vibration force acting on the support. Centrifugal force balancing machine can be divided into single-sided balancing machine and double-sided balancing machine according to the number of correction planes. Single-sided balancing machines can only measure unbalances (static unbalances) on one plane, while double-sided balancing machines can measure dynamic unbalances, as well as static unbalances and even unbalances separately.

In addition, the centrifugal force balancing machine can also be divided into soft support balancing machine and hard support balancing machine according to the different supporting characteristics. The support stiffness of the soft support balancing machine is small, and the signal detected by the sensor is proportional to the vibration displacement of the support; The support stiffness of the hard support balancing machine is large, and the signal detected by the sensor is proportional to the vibration force of the support.

Fourth, the application and significance of balancing machine

Balancing machines play a vital role in the manufacturing process, especially in the manufacturing of rotating parts such as motor rotors, machine tool spindles, fan impellers, steam turbine rotors, automotive parts, and air conditioning blades. By balancing and correcting these rotating parts, you can ensure that they run smoothly and improve the quality and performance of your products.
