DYNAMIC BALANCING (Two plane balancing)
In Dynamic balancing, the weight will be added in two planes as indicated in Fig.9.
This kind of adding weights in two planes will eliminate the possibility of Force couple.
With the result, there will not be any undesirable dynamic forces left out in the wheels.
Since the weights are added in two planes, this is also called as Two Plane Balancing.
Normally for Four Wheelers, Two plane balancing is recommended and today's
computerized Wheel balancing equipment are following this technique only.

PRINCIPLE OF OPERATION
Wheel balancer is a DSP based Wheel balancing equipment. The Balancer calculates
the unbalanced mass and the position of unbalance over the width of the wheel.
The two planes of the wheel are the Inner and Outer faces of the wheel (in the case of
normal rims) where the balancing weights can be fixed. In Alloy rims the location of
weights will be different based on the configuration of Alloy rim (refer Chapter 7.4.1).
The Diameter, Width of the Rim and the Rim distance are the inputs to the equipment
for calculating the unbalance. When the distance from the equipment and the inner
face of rim is entered the system takes it as the Inner plane location of the Balancer.
When the Rim width is entered the system adds the width with the inner plane distance
and takes it as the outer plane location. When the Diameter is entered the system
takes it as radial distance from the centre of wheel to where the weights to be added.
When the wheel is rotated the system detects any unbalance on the shaft. The Inner /
Outer unbalance window displays the unbalanced mass in the respective planes. The
measurement will be taken if only the set RPM is reached.

WHEEL BALANCING WEIGHTS
The weights must be fixed firmly on to the rim for proper balancing and to
avoid repeated runs
TYPES OF WHEEL BALANCING WEIGHTS
Clip-on type weight
Sticker (adhesive) type weight
Clip-on type Wheel balancing weights can
be used for Steel rims with less thickness
Sticker type Wheel balancing weights can
be used for Alloy rims with more thickness
