Glossary of balancing technology

All | A B D E F G H I J K L M N P Q R S T U V W Z
Belt drive
Mechanical drive of a balancing machine consisting of motor, pulleys, drive belt and belt tensioner. The diameters of the motor pulley and the drive diameter of the rotor should not be too similar in order to avoid the occurrence of apparent imbalances.
Limited original imbalance
Limiting the initial imbalance by balancing the individual parts, well-considered design and targeted production and assembly.
Operational balancing
Balancing of a rotor not in a balancing machine, but in the operating bearing.
Operating balancer
Measuring system for balancing outside a balancing machine in operating condition.
Operating speed
Speed at which a rotor rotates during operation.
Related unbalance
Amount of static unbalance in relation to the mass of the rotor in gmm/kg or µm.
Reference plane
Radial rotor plane to which an unbalance is referred.
Bending mold
Characteristic bending line with which a rotor deforms at a critical speed.
Bending-critical speed
Speed at which maximum deflection of the rotor occurs and this is significantly greater than the movement of the bearing journals.
Bode diagram
When balancing, the course of the magnitude and angle of an oscillation at rotor speed or twice the rotor speed over the speed.
