Understanding Dynamic Balancing


There are certain machines that need to be properly balanced before they can be put to good use. Unless a machine has been adequately balanced, it will not be able to perform to its maximum efficiency. There are two ways of balancing a machine: static balancing and dynamic balancing. Static balancing refers to balancing a machine that is in a stationary position and when the centre of gravity of the machine is aligned with the axis of rotation of the object. This ensures that the object does not move from its position during the balancing and the axis is kept horizontal. No braking force is used, and static balancing doesn’t have any tendency to rotate either.

However, the applications of static balancing are generally limited, and dynamic balancing in Melbourne is the preferred choice in most situations. Dynamic balancing is the process of balancing when the rotation of the machine does not result in any centrifugal force or a coupling effect. The system continues to rotate without requiring any external force or coupling whatsoever, except what’s needed to support the weight of the machine. If a machine is unbalanced, it puts undue stress on the bearings. In case the machine is used for longer periods of time, there’s a chance the bearings will give way completely. In order to combat this issue, a counterbalancing weight is added. Dynamic balancing is generally preferred in order to balance the rotating machines.

How Is it Done?

The parts of the machine are rotated quickly, and the imbalance between each part is measured using sophisticated electrical equipment. Needless to say, this is not a job you can complete on your own. You will need to call a professional company that specialises in offering dynamic and static balancing services to balance the machine. The imbalance is calculated and then added or subtracted from the counterweight added until the excessive vibration from the bearings is minimised. The aim is to reduce the vibration to as low a level as possible.

The Difference between Static and Dynamic Balancing

Both static and dynamic balancing have very different applications; one is done when the object is stationary, while the other is done when the object is in motion. In order to achieve any form of balance, the centre of gravity of the machine must be aligned over the support base of the user. In some cases, balancing may also involve shifting the centre of gravity to the axis of rotation. In dynamic balancing, no external force or couple is needed to rotate the object, other than the force needed to move its own weight.

Unbalanced parts can lead to a catastrophic failure if you do not take action right away. If you notice excessive vibration in the bearings every time you use the machine, it could indicate a serious problem with the equipment. You have to call a balancing company right away to balance the machines, or risk a total break-down, which could end up causing even more money in the long run to fix.
