DSP9200 Series Balancer Operation Instructions

6. GLOSSARY

The amount of force or the intensity of the vibration.
When the wheel requires the cone to center the wheel on the balancer's shaft from the
backside, primarily due to the chamfer of the wheel. Also referred to as Back-Cone
Mounting.
The distance measured from the mounting face to the back edge of the wheel.
The abbreviation for bottom dead center also referred to as 6 o'clock.
The process of seating the tire to the rim bead seats. Bead seating preferably occurs just
after the tire and rim have been assembled, but may gradually change and optimize over
a longer period. If loaded with the GSP9200 load roller or driven, the position of the bead
may optimize or always remain seated improperly, unless the tire is demounted,
lubricated, and remounted. However, the load force and its' relatively short duration will
not necessarily solve defective mounting of the tire bead seat to the rim seat.
The diameter of an imaginary circle drawn through the center of each lughole, and
virtually always on the same centerline as the hub bore of the wheel.
A device used to determine the frequency of the vibration by isolating the vibrations with
the greatest magnitude.
One complete disturbance.
To decrease the magnitude of a vibration or sound.
Used to reduce the magnitude of a given vibration. Rubber is commonly used to isolate
and dampen vibrations.
®
The inner and outer electronic arms on the GSP9200. By positioning the Dataset arms
and entering data using the foot pedal, rim dimensions can be recorded for balancing.
A procedure that balances the wheel assembly by applying correction weights in two
planes so that up and down imbalance and side to side imbalance are eliminated.
A device used much like a doctor's stethoscope and is for noise diagnosis problems only.
Vibrates when energy is applied.
Continues to vibrate after the outside energy stops.
