Glossary Of Terms
Balancer Flange – Disk that mates with the disk of
the wheel mounted to the balancer. The flange also
serves to keep the wheel perfectly perpendicular to its
axis of rotation.
Balancing Cycle – Sequence of operations performed
by the user and the machine, beginning from the start
of the wheel spin to the time that the wheel is stopped;
at a standstill, after the out of balance signals are
acquired and the relative values calculated.
Centering – Procedure for positioning the wheel on
the spindle shaft with the aim of ensuring that the
rotational axis of the wheel is aligned with the center
of the shaft.
Centering Flange (accessory) – Device serving to
support and center the wheel. Also keeps the wheel
perfectly perpendicular to its axis of rotation. The cen-
tering flange is mounted to the balancer shaft by means
of its center hole.
Cone – Conical components with center hole. When
inserted on the spin shaft, serves to center wheels with
centre holes whose diameter is between maximum and
minimum values.
Dynamic Balancing – Operation in which out of bal-
ance is corrected by the application of two weights, one
on each side of the wheel.
Self-calibration – A procedure whereby suitable cor-
rection coefficients are calculated by starting from
known operating conditions. Self-calibration improves
the measurement precision of the machine by correct-
ing, within limits, calculation errors that may arise due
to alteration of the machine’s characteristic over the
course of time.
Spin – Procedure starting from the action that causes
the wheel to rotate and the successive free rotation of
the wheel.
Hubnut – Device for clamping the wheel to the bal-
ancer. The hubnut 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 unbalance is corrected. This is achieved
by fitting a single weight, usually at the center 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 hubnut to clamp the wheel. This
component is supplied disassembled from the machine.
Unbalance – Non-uniform distribution of the wheel
mass that results in the generation of centrifugal force
during rotation.
