What is Dynamic Balancing?
Dynamic balancing, simply put, is a method through which we balance the moving parts of a machine, or piece of industrial machinery. To do this, we rotate these parts at high speeds. When we do this we are able to gain a measurement of the imbalance within each individual rotating component. At WDB we have the industry’s most up-to-date diagnostic tools which boast precision electronic sensors. These in turn illustrate the level of vibration within the unbalanced component. At WDB group we invest heavily in the latest dynamic balancing calculators, which means we are able to work to extreme precision as well as to be ahead of all our competitors.
What are some examples of Dynamic Balancing?
There are many examples of how we use dynamic balancing to increase performance. Common applications for dynamic machine balancing are engine crankshafts and automobile tires. As well as balancing services for drive shafts and flywheels. These are examples from the automotive industry. Other examples include dynamic balancing of impellers, industrial fan balancing, flail rotor balancing and machine rotor balancing. We can literally perform dynamic balance analysis on any machine and its components.
Why is Dynamic Balancing Important?
The primary goal of any equipment is to possess an operation that is free from vibration. However, vibration will always be part of any machine that rotates, and some vibration levels can be acceptable. Instead of trying to get rid of all vibration in the machinery, it is necessary to search for machinery balance as far as possible. This process minimises the vibration until there are fewer levels of noise. In addition to this, reduced vibration can extend the lifespan of your machinery. Many of our new customers say that they did not realise just how beneficial dynamic balance services were on boosting their operational performance.
What is the difference between static and dynamic balancing?
Static balancing
An example of balancing is static balancing. To achieve this balance, use low friction bearings to enable your machine to settle, in that the heaviest part is at the bottom. You can remove material from the lower portion or put it to the top part until it rotates on a true axis. We repeat the method of static balancing over and over again, until the point which is heavy disappears.
When a section is balanced statically, its centre of gravity is located in the axis of its rotation. This process implies that it will remain stationary at the horizontal axis, without applying a braking force.
Dynamic balancing
We perform dynamic balancing by attaching sensors on the bearing pedestals. It enables imbalance identification on two planes for correction to occur. It uses the machines for determining the imbalance point and gives a correction. During this procedure, the sensors in the devices provide data to the computer as the machine rotates. We predetermine the rotation speed as part of the test.
This process will offer information on the exact weight amount that needs to be added or removed to bring back balance to areas that are very light or heavy

Static Balancing vs Dynamic Balancing
Balancing is the complex procedure of working to enhance the mass spread of a body so as to rotate in its bearings without the unbalanced centrifugal forces acting on it. But what’s the difference between static and dynamic balance?
View PostWhat are the benefits of dynamic balancing?
Dynamic balancing means a lot to the mechanical and engineering industry. When the machine is running in balance, it is working as it should be. A lot of consequences could happen if you are using a smooth and well-balanced machine. For instance, the results of dynamic balancing could result in:
Less noise
Increased safety
Reduced downtime
There could also be less noise after we perform dynamic balance. This is because the vibration which causes airborne noise will no longer be present. In addition, you will also address operator fatigue which is caused by exposure to excessive noise and vibration. This procedure will consequently help to improve the operator’s efficiency.
The operator’s safety is also going to improve because the failure of machines is less likely to happen.
Additionally, balancing the machine extends the life of the bearing. It is also important to note that because of the reason that vibration occurs due to an imbalance which gets absorbed by the nearby structure. When a machine is operating in balance, it minimises the structural stress. Finally, regarding the productivity; the rise in the uptime boosts productivity.
