6.4.5.2 Geometric matching with only the rim
(
Fig. 6-55
)
• After having clamped the rim to analyse on the
balancer, press F6 on the “OPTIMA MATCHING”
screen.
• Lower the wheel guard and press the
START
key: the laser scanners carry out the runout
measurement in the bead seats. At the end of the
measurement the control software prompts the
alignment of the rim valve at 12 o’clock (
Fig. 6-56
).
• Press
F6
to confirm.
• Release the rim and move it to the tire changer to
fit the tire (
Fig. 6-57
).
• After the tire changer, clamp the wheel (rim + tire)
on the balancer and confirm with
F6
.
• Lower the wheel guard and (if necessary) press
START
: the balancer will proceed with the runout
calculation with the tire fitted.
To carry out the geometric matching of the comple-
te wheel proceed as indicated in the “Geometric
matching” section (
F
6.4.5).
6.4.5.3 Rim Only Diagnosis
Optima can be used to perform an analysis of the
rim only and to process data independently of the
tire, for the rim only.
If only the rim is clamped, the machine always
automatically recognises the presence of a rim
without the tire.
To activate the “Rim only diagnosis” function:
• enable “1” in the “Optima Parameters” screen at
the “RIM ONLY” item.
• start the run.
During the run measurements are taken on the
lateral internal profiles and on the bead recesses
(
Fig. 6-58
).
The laser reading positions on the rim are the same
as the contact points obtained with a circle with
16mm diameter, as shown in
figure 6-59
.
When the run is complete, the graph showing the
curves for the radial Run-out of the right and left
bead recesses appears (
Fig. 6-60
).
