What is Dynamic Balancing?

Dynamic balancing is a way of balancing machines by rotating parts quickly and measuring the imbalance using electronic equipment. The imbalance measured can then be corrected by adding or subtracting weight from the rotating parts until the vibration is reduced."

Basically, all machines have some form of residual vibration. Enormous vibration in rotating machinery can cause high levels of noise and more importantly, significantly reduce the life of components. So, the ideal thing to do would be to remove all causes of vibration and allow the machine to run completely smooth. The process of balancing is the removal or addition of weight to the device, so that this effective mass centre approaches the true axis.

In addition to dynamic balance, there is also static balance. When a part is statically balanced, the centre of gravity is on the axis of the rotation. This means the part will stay stationary at a horizontal axis, without the application of braking force. It also has no tendency to rotate due to the force of the gravity.

The ultimate goal in any piece of equipment is to have it operating free of any vibration while running smoothly for a long time. In reality, however, vibration is always going to be a part of any rotating machinery, and certain levels of vibration may even be acceptable. Rather than trying to remove all vibration from the machinery, it is beneficial to seek to balance the machinery to the greatest extent possible. This reduces vibration to the point of reduced noise levels, and the existing vibration doesn’t affect machine life.

Dynamic balancing is performed with sensors attached to the bearing pedestals. It allows for the identification of the imbalance on two planes so that a real correction can take place. It makes use of machinery to identify the point of the imbalance and correct it. Other factors to consider are the length of the machine as well as its operating speed.
