Mechanical Vibration - Rotor Balancing - Part 11: Procedures and Tolerances for Rotors with Rigid Behaviour
Also Known As:
The DIN ISO 21940-11 standard provides guidelines and specifications for rotor balancing procedures and tolerances for rotors with rigid behavior. It outlines the necessary requirements for unbalance tolerances, the number of balancing planes needed, and procedures for verifying the unbalance. The standard also includes recommendations for the required balance grade (G) based on the type of machinery and its highest operating speed.
The standard emphasizes the importance of ensuring acceptable balance quality in rotors with rigid behavior to prevent any potential issues during operation. It establishes acceptance criteria for checking the residual unbalance, ensuring that the rotor meets the specified standards.
However, it is important to note that this standard does not cover rotors with flexible behavior. This means that the standard is not applicable to rotors that exhibit significant deformation or flexibility during operation. The standard focuses solely on rotors with rigid behavior, providing clear procedures and tolerances for achieving the desired balance quality.
