Our Experts in Balancing
Universal Balancing is one of our trusted partners for high-speed balancing. Based in Bristol, U.K., Universal Balancing manufactures static and dynamic balancing machines for automotive, aerospace, and other applications.
CIMAT, headquartered in Bydgoszcz, Poland, manufactures high-tech balancing machines and special balancers for mechanical, control system, manufacturing, and electrical and mechanical assembly.
Balancing is the process of designing or modifying machinery so that unbalance is reduced to an acceptable level, or if possible, eliminated entirely. Rotating or reciprocating parts should be completely balanced, or stress on various parts and dangerous vibrations will become apparent.
To identify the position and amount of unbalance, balancing machines are used by a manufacturer to correct any unbalance that exists. These machines are so sensitive that they can easily and accurately identify any mass axis 0.001mm off the running axis.
Types of Unbalance
There are three types of unbalance:
Static unbalance – is where the mass axis is displaced only parallel to the shaft axis. The unbalance is corrected only in one axial plane.
Couple unbalance – is where the mass axis intersects the running axis. For example: a disk that has swash run-out with no static unbalance. The unbalance is usually corrected in two planes.
Dynamic unbalance – is where the mass axis is not coincidental with the rotational axis. This unbalance is usually a combination of static and couple unbalance and is corrected in two planes.
Methods of Correcting Unbalance
Removal of material by drilling, milling etc from the heavy position on the component is used to correct the unbalance. Alternatively it can be corrected by adding material to the “light” position on the component by bolting or welding balance weights to reduce unbalance.
There are balance limits, just like machining limits, where the unbalance is acceptable. International and national standards are quoted for rotors, for example: car wheels are balanced to a limit of grade 40 and small electrical armatures are balanced to grade 2.5. The grades are converted to unbalance units, depending on the rotational speed of the rotor as per ISO 1940 standards.
