What Is Balancing Machine
A balancing machine is a measuring tool used for balancing rotating machine parts such as rotors for electric motors, fans, turbines, disc brakes, disc drives, propellers and pumps. The machine usually consists of two rigid pedestals, with suspension and bearings on top supporting a mounting platform. The unit under test is bolted to the platform and is rotated either with a belt-, air-, or end-drive. As the part is rotated, the vibration in the suspension is detected with sensors and that information is used to determine the amount of unbalance in the part. Along with phase information, the machine can determine how much and where to add or remove weights to balance the part.
Importance of Balancing Machine
Balancing machine is a critical aspect of rotating equipment design, operation, and maintenance, as it ensures the proper distribution of mass and forces within the system. The importance of balancing machine in rotating equipment can be summarized as follows:
Prevents excessive vibration: Balanced rotating equipment operates smoothly without excessive vibration. Unbalanced equipment can generate high levels of vibration, leading to increased stress on components, increased wear, and potential damage to equipment over time. Excessive vibration can also cause noise, discomfort for operators, and structural damage to the surrounding environment. Balancing machine helps minimize vibration, ensuring smooth operation and reducing the risk of equipment failure.
Enhances equipment performance: Balanced rotating equipment performs optimally, leading to improved operational efficiency and effectiveness. Unbalanced equipment can result in reduced performance, increased power consumption, decreased efficiency, and compromised system performance. Proper balancing machine helps ensure that equipment operates at its designed performance levels, maximizing productivity, and minimizing energy consumption.
Extends equipment life: Balanced rotating equipment experiences less wear and tear on components, leading to longer service life. Unbalanced equipment can result in increased loads, stresses, and premature wear on bearings, shafts, couplings, and other components. Proper balancing machine helps reduce the risk of premature failure, extending the operational life of equipment and minimizing maintenance costs.
Enhances safety: Balanced rotating equipment is safer to operate. Unbalanced equipment can generate excessive vibration and forces, leading to potential safety hazards for operators and other personnel. For example, excessive vibration can cause equipment to shake, become unstable, or malfunction, posing risks of slips, trips, falls, or other accidents. Proper balancing machine helps minimize such risks, ensuring a safe working environment for operators and other personnel.
Reduces downtime and maintenance costs: Balanced rotating equipment experiences fewer failures, resulting in reduced downtime and maintenance costs. Unbalanced equipment can cause increased wear on components, leading to more frequent repairs, replacements, and maintenance activities. Balancing machine helps minimize wear and tear on components, reducing the frequency of maintenance interventions and associated costs.
Attributes of a Balancing Machine
The following features characterize a good balancing machine:
● High accuracy.
● Repeatable measurements.
● Easy to set up and operate.
● Adaptable to a wide range of parts.
● Permanent calibration – no need for time consuming calibration runs.
● Eliminate/minimize outside influences on measurements.
● Reliable and dependent design.
● Good customer service and support.
Unbalance is a vector quantity, i.e. it has a magnitude and a direction. The magnitude of the unbalance is defined as a composite product (multiplication) value of mass (m) times radius (r). m x r. This is the measured quantity internally in balancing machines. The user feeds a radius of correction desired r, and the machine computes the unbalance mass m based on the measured unbalance value. The direction of the unbalance is the angle measured from a known reference on the balancing machine. Thus the units in metric will be g-mm. An example of unbalance would be 10 g-mm @ 45 degrees. The reference could be fixed on the rotor, like a reflective sticker, or internally in the machine. In some literary references, the unbalance is referred in terms of eccentricity, measured in microns for the metric system. This measurement normalizes the unbalance with respect to the rotor weight. I.e, it is the unbalance divided by rotor weight or mxr/M, where M is the mass of the rotor. While doing the division, take care to use consistent units, i.e. if mxr is units of g-mm, M should be in grams.
For practical unbalance correction, one needs to know the unbalance value in a weight value say grams. This is achieved by dividing the unbalance value by the radius. Thus a 50 g-mm unbalance at 100 mm radius, needs a correction of 50 g-mm/100 mm, i.e. 0.5 grams.
Modern balancing machines supplied by Precibalance indicates both the g-mm value as well as the value in grams as well as a combination of many other non metric mass and length units such as oz-in, lb-in etc.
For interpretation of the effect of unbalance, the magnitude is the relevant value. The angle is relevant for determining the location of the unbalance. The angle can be any value between 0 to 360 degrees on the rotor. Thus a component with unbalance of 5 g-mm @ 355 degree is better balanced than one at 10 g-mm @ 5 degree.
It should be noted that for quantifying and comparing the effect of unbalance masses, both the unbalance mass and radius is important. This is because the centrifugal force generated by a rotating mass is m x ω x ω x r, where m and r are the unbalance mass and radius of correction and ω is the angular velocity defined as ω = 2*pi*RPM/60. Normalizing with the RPM, the centrifugal force generated by the unbalance is quantified by the product m x r. So, a 10 grams unbalance at 100 mm radius, i.e. 10×100 = 1000 g-mm of unbalance has the same effect as a 20 grams unbalance at 50 mm radius, i.e. 20×50 = 1000 g-mm.
How Does the Balancing Machine Work
Balancing machines measure, analyse, and correct unbalance in rotating components. The general process includes:
Component is mounted on the support system: The machine can accommodate different sizes and shapes of components.
Component vibration is measured: Sensors, such as accelerometers or laser sensors are used to collect data regarding the amplitude and phase of the vibrations.
Data is analysed: This analysis helps to determine the type and amount of unbalanced in the component, as well as the location and magnitude of the heavy spot.
Unbalance correction: The amount of weight which needs to be added or removed to achieve balance is calculated typically by adding counterweights.
Balancing is carried out: Balance weights are applied (using bolts, welding, adhesive or balance putty) at specific locations on the component to achieve balance.
Component is remeasured: Once weight has been added or removed, the component is re-measured to check the unbalance has been reduced to an acceptable level. This may be repeated to achieve desired balance.
There are three types of balancing machines:
Balancing machines for universal balancing
These devices can detect both static and dynamic imbalance.
Balancing machines for dynamic balancing
These devices solely measure dynamic imbalance.
Balancing machines for static balancing
