Question: Why is balancing necessary ?
Answer: Balancing is necessary to ensure that rotating components operate smoothly.
This is because Unbalance causes centrifugal forces on the rotors support bearings, and this has a number of consequences, including:-
Reduced Service life:
Bearings, suspensions, housings and foundations can be subjected to very high stresses caused by vibrations resulting from unbalance and these result in greater wear. Products with unbalanced parts often have a shorter service life.
Vibrations can loosen screwed and clamped components. Electric switches are destroyed by vibration, pipes and cables can fracture at the connections. Unbalance can substantially reduce a machine’s operating safety – man and machine are at risk.
A irregularly running electric tool cannot be precisely used. The user’s effort increases they become tired more quickly. Vibrations also have a substantial negative effect on the production result of machine tools: A grinder or high-speed woodworking machine produces untidy work and produces more rejects if the spindle and tools have not been precisely balanced.
Irregular, noisy running is always used as a quality assessment criterion and so vibrations can have a substantial negative effect on a product’s competitiveness: A highly vibrating household appliance and a noisy car are products which will not be successful on the market.
Personal Comfort and Health:
Excessive vibration and noise cause discomfort, fatigue and in some cases injury to operators, users and bystanders.
