Introduction of balancing

Balancing of forces is most important in any machinery industries. Unbalance of forces is produced in rotary or reciprocating machinery due to the inertia forces associated with the moving masses. 

What is balancing?

Balancing is the process of designing or modifying machinery so that the unbalance is reduced to an acceptable level and if possible is eliminated entirely. 

Many serious problems encountered in high-speed machinery are the direct result of unbalanced forces. These forces exerted on the frame by moving machine members are time-varying impact vibratory motion to the frame and produce noise. There are some human discomfort and detrimental effects on machine performance and the structural integrity of the machine foundation. 

The most common approach to balancing is by redistributing the mass which may be accomplished by addition or removal of mass from various machine members. 

There are two basic types of unbalance :
  1. Rotating unbalance
  2. Reciprocating unbalance 
They both occur separately or in combination too. 

There are also two types of balancing system : 
  1. Static balancing 
  2. Dynamic balancing 
If we consider balancing whether it is static or dynamic but balancing can help to extend the service life, quality and accuracy of your machine while unbalanced parts can lead to breaking down to your machine. There is some difference between static and dynamic balancing
