The balancing machine is mainly used to measure the unbalance of the rotor, and is corrected according to the unbalanced amount measured to improve the mass distribution of the balanced rotor, so that the vibration of the journal or the force acting on the bearing during the operation of the rotor is reduced to the prescribed Within the scope of.
Therefore, the main function of the balancing machine is measurement, and sometimes a correction device is attached to improve the balance efficiency.

First, the classification of the balance machine:
Despite the variety of balancing machines, we can distinguish between the working principles and the application of their products.
A. From the principle points: there are centrifugal balancing machine (dynamic balancing machine) and gravity balancing machine (static balancing machine); soft bearing balancing machine; hard bearing balancing machine;

Centrifugal and gravity balancing machine
Centrifugal and gravity balancing machines are two types of typical balancing machines.
Gravity balance machine: This balance machine relies on the gravity of the rotor itself to measure the static unbalance in the state where the rotor is not rotating. It is also in the category of static balance machine. This type of balancing machine does not need to rotate the workpiece during measurement. It is especially suitable for balancing workpieces and large disk parts that are deformed during rotation, such as unsintered grinding wheels, train wheel brake discs, aircraft propellers, aviation tires, etc.
Centrifugal balancing machine: From the structural principle of the balancing machine, the most common one is the centrifugal balancing machine, which is a balancing machine that measures the rotor imbalance according to the vibration displacement or vibration force caused by the unbalanced centrifugal force of the rotor in the rotating state. Among them, the centrifugal balancing machine for double-sided or multi-face balancing is a so-called dynamic balancing machine, and the centrifugal balancing machine for single-sided balancing belongs to the category of static balancing machine.

2. Soft support dynamic balancing machine and hard support dynamic balancing machine
Soft bearing balance machine: A soft-bearing dynamic balancing machine is called a balanced dynamic speed higher than the natural frequency of a rotor-support system. The balance of the balance machine is small, and the signal detected by the sensor is proportional to the vibration displacement of the support. It has the characteristics of small influence from external vibration signals, high measurement accuracy, and is suitable for mass production.
Hard-bearing balance machine: A hard-supporting dynamic balancing machine whose balance speed is lower than the natural frequency of the rotor-support system. The balance of the support machine is large, and the signal detected by the sensor is proportional to the vibration force of the support. It has the characteristics of being able to balance at low speed, easy to operate and good safety performance.

B. From the application point of view:
There are horizontal balancing machine and vertical balancing machine; universal balancing machine and special balancing machine.

1. Horizontal balance machine and vertical balance machine
The horizontal balancing machine is a balancing machine that is horizontally balanced on the balancing machine by the axis of rotation of the balancing rotor. Generally, a rotor with a rotating shaft or a process shaft can be assembled, such as a motor rotor, a machine tool spindle, a drum, a fan, a steam turbine, and a supercharger. The device is suitable for horizontal balancing machines.
The vertical balancing machine is a balancing machine that is vertically inclined on the balancing machine by the axis of rotation of the balancing rotor. Generally speaking, the disk itself has a disk-shaped workpiece without a rotating shaft such as a gear, various automobile flywheels, a clutch, a pressure plate and an assembly thereof. Brake discs, brake hubs, clutches for motorcycles and magneto-motor rotors, fans, blades, pump impellers, pulleys, grinding wheels, etc.

2. Universal balancing machine and special balancing machine
The universal balancing machine is a balancing machine that balances multiple rotors within the specified rotor weight and speed range.
The special balancing machine is a balancing machine that balances a certain type of rotor within the specified rotor weight and speed range.

The above is the distinction between the types of balancing machines. When we use the dynamic balancing machine, we must carry out good maintenance and maintenance on it, so as to extend its service life.

Guangzhou Zhuo Xuanjin engineers reminded that the dynamic balancing machine is a high-precision measuring instrument. The maintenance personnel are required to have certain electrician knowledge, especially the knowledge of weak electricity. For this reason, the professional technicians who choose to identify it should be repaired as much as possible. After-sales service consultation telephone: 020-36969823.
