Glossary

ALUS -Alloy wheel mode that typically requires the

use of one or two adhesive weights for correction.

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 braked to

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 out of balance 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.

Out of balance – Non-uniform distribution of the

wheel mass that results in the generation of centrifugal

force during rotation.
