What is the operation method of dynamic balancing?
2 Answers
The operation method of dynamic balancing is: 1. Remove the tire logo and install the tire on the dynamic balancer, select the appropriate size fixture, pull out the ruler on the dynamic balancer to measure, and input the first controller; 2. Take out the rear curved ruler to measure the rim width, and input it into the second controller; 3. Input the rim diameter into the controller and press start; 4. When the detection stops, the computer will measure the weight of the counterweights needed to be added to the inside and outside of the rim. Install the outer side first, rotate the tire, and hammer the counterweights according to the prompts. Dynamic balancing refers to the balance between the wheels during the operation of the vehicle. The need to add balancing weights is because the mass distribution of each part of the tire cannot be very uniform during manufacturing. When the car wheels rotate at high speed, a dynamic imbalance will occur, which will be reflected on the steering wheel, causing the steering wheel to shake or vibrate.
I still remember the scene clearly when the mechanic did wheel balancing for me during my last tire replacement at the repair shop. First, the entire wheel had to be removed and mounted on the balancing machine, which had a cone in the center to secure the rim. Once started, the machine would spin the tire at high speed, allowing the equipment to detect any weight imbalance in the tire. Just like a seesaw, the heavier side would tilt downward, and the machine would display how many grams of lead weights needed to be added. The mechanic would then use a small hammer to tap the lead weights onto the inner or outer side of the rim—sometimes both sides needed weights. The process was repeated until the machine showed all values returning to zero. This job had to be done only when the tire was completely cool, and any old lead weights on the rim had to be scraped off first.
