In rotating machinery, the rotor is one of the most important workpieces. In order to ensure the uniform distribution of the rotor mass, the balance of the rotor is measured using a dynamic balancing machine. According to the standard, the imbalance of the rotor may be due to material unevenness, process error, uneven deformation of the rotor blade, uneven wear or partial blockage. There is always an imbalance on the rotor. Rotor imbalance is the main source of excitation for the engine. Unbalance causes rotor vibration, accelerates wear of bearings, shaft seals, etc., reducing machine life and efficiency. For this reason, during engine manufacturing or maintenance. Even during operation, the rotor needs to be dynamically balanced.

1. A material or blank for the manufacture of a rotor. In mechanical engineering, many rotor imbalances are caused by the material itself. For example, when casting a rotor, the density distribution of the raw material itself is not uniform, the slab has trachoma, porosity, porosity, coupling with uneven distribution of welds and other defects, and there is more or less possible rotor imbalance. .
2. The rotor is unbalanced during long-term work. During high speed rotation, the rotor wears and deforms. At the same time, the rotor may be deformed due to temperature changes during operation, and centrifugal forces during operation will enable components between the components. Relative displacement occurs, and the relative displacement destroys the original equilibrium state. There will be significant vibrations over time.
3. Causes the rotor machining assembly to be unbalanced. When the rotor is machined and installed, the machining accuracy and installation error will affect the mass distribution around the rotor, resulting in rotor imbalance.
4. The rotor is unbalanced during the repair process. During the maintenance process, such as the normal technical maintenance such as the disassembly and replacement of parts, there is also the possibility of uneven distribution of the rotor mass. It is not certain that the influence on the balance state of the rotor is large or small. Therefore, in order to ensure the normal use of the rotor, the dynamic balance measurement of the rotor must be performed after each repair and maintenance.
