What are the 3 inputs required to be entered into the wheel balancing machine before a wheel can be balanced?
Before a wheel can be balanced, wheel dimensions must be entered into the computer on your unit. These include: A = Offset – The distance measured from the balancer (“0” on offset arm) to inner plane of the wheel rim (inner weight location). W = Width – The width of the wheel at the rim flanges, measured with calipers.
How do you know where to install wheel weights when balancing a tire?
“The best placement would be at the extreme inside and outside of the wheel.” The farther apart the weights, the more “couple” force, or the side-to-side wobble of a rolling tire, can be counteracted. “We’ve lost the outside and two or three more inches because the weight has to be behind the spokes.
How does a dynamic tire balancer work?
Dynamic Wheel Balance A computer wheel balancer spins the wheel and determines the locations and amounts of vibration. The computer splits the tire into two halves and measures both lateral and radial forces on each side of the tire’s center. Weights are added to each side of the wheel to correct the imbalance.
Do you have to calibrate wheel balancer?
The main reason a balancer needs to be re-calibrated is because it begins to “chase weight”. “Chasing weight” means the balancer continues to ask for more weight once the first weight is applied. At this point, the machine needs to be calibrated.
What is static wheel imbalance?
Static imbalance occurs when there is a heavy or light spot in the tire, causing it to roll unevenly in an up-and-down movement. Dynamic imbalance occurs when there is unequal weight on both sides of the tire/wheel assembly centerline, causing a side-to-side movement.
Can you balance a tire without weights?
Some places put the weights on the backside as to not damage your nice wheels. They could have used stick on weights instead of the kind that clamp to the bead. It is however possible to have no weights but unlikely. If you don’t know where you’re going, any road will take you there.
What is the difference between static balancing and dynamic balancing?
Static balance refers to the ability of a stationary on object to its balance. This happens when the objects centre of gravity is on the axis of rotation. Whereas dynamic balance is the ability of an object to balance whilst in motion or when switching between positions.
Is static balance good enough?
Long before the spin balancer was invented all tires were balanced by a bubble balancer. If done properly, the 4 point static balance is as good and accurate as any other method. The most effective bubble balance is accomplished on both inner and outer portions of the tire rim.
At what speed are tires balanced?
Dynamic balance In the tire factory, the tire and wheel are mounted on a balancing machine test wheel, the assembly is rotated at 100 RPM (10 to 15 mph with recent high sensitivity sensors) or higher, 300 RPM (55 to 60 mph with typical low sensitivity sensors), and forces of unbalance are measured by sensors.
