There are many terms in the balancing machine industry. What are the commonly used ones, and what do they mean? Today, our editor will introduce some of the more common terms and their meanings in the balancing machine industry.

(1) Unbalanced quantity

Unbalanced mass refers to the magnitude of unbalance on a specific plane of the rotor within a balancing machine, which does not involve angular position. Its calculation method is the product of unbalanced mass and the distance from the mass's center of gravity to the rotor's shaft, typically measured in units of g.mm or g.cm, and is also known as "weight-to-diameter product."

(2) Imbalance Degree

Imbalance degree refers to the unbalance amount of a few rotors' unit mass (in units of g.mm/kg) relative to the mass eccentricity of the rotor (in units of μm) during static unbalance.

(3) Unbalanced Phase

Unbalanced phase refers to the angle of the unbalanced mass on a rotordynamic balancing machine relative to a given level coordinate.

The unbalanced mass on a plane of the rotor of the dynamic balancer is relative to the given polar coordinate angle value.

(4) Initial imbalance quantity

The initial unbalance is the amount of unbalance that exists in the rotor before it is balanced.

(5) Remaining imbalance quantity

Residual unbalance refers to the remaining imbalance value of the rotor after correction by a balancing machine.

(6) Allowable Unbalance

The permissible unbalance quantity refers to the remaining unbalance that can be tolerated while ensuring the workpiece operates normally. This indicator, when expressed in terms of unbalance degree, is known as the permissible unbalance degree (also referred to as the permissible unbalance rate).

(7) Dynamic Balancer Calibration Radius

The dynamic balancing machine correction radius refers to the distance from the center of mass of the corrected mass on the correction surface to the shaft axis of the rotor, typically measured in millimeters.
