IMBALANCE
Non-uniform distribution of the wheel mass that results in the generation of centrifugal
force during rotation.
SELF-CALIBRATION
A procedure whereby suitable correction coefficients are calculated by starting from
known operating conditions. Self-calibration improves the measurement precision
of the machine by correcting, within limits, calculation errors that may arise due to
alteration of the machine's characteristics over the course of time.
SENSOR (Measuring arm)
Mobile mechanical element brought into contact with the rim in a preset position to
measure its geometrical data. The data can be measured in automatic mode if the
sensor is equipped with suitable measurement transducers.
SPIN
Procedure starting from the action that causes the wheel to rotate and the successive
free rotation of the wheel.
SPINNER
Device for clamping the wheel to the balancing machine. The spinner features
elements for engaging to the threaded hub, and lateral pins that are used to tighten it.
STATIC BALANCING
In static balancing only the static component of the imbalance is corrected. This is
achieved by fitting a single weight - usually at the centre of the rim channel. The
accuracy of this system increases as the width of the wheel decreases.
THREADED HUB
Threaded part of the shaft that is engaged with the spinner to clamp the wheel. This
component is supplied disassembled from the machine.
