Balancing machine

What is a balancing machine?

A balancing machine is used to measure rotating machine parts like rotors on pumps, propellers, disc drives, disc brakes, turbines, fans and electric motors. The machine normally has two rigid pedestals that have bearings and suspension on top of a supporting mounting platform. This unit under test has been bolted on a platform and is rotated using an end driver or a belt or air. When the part is being rotated, its vibration at the suspension will be detected by the sensors, and such information is then used for determining the level of unbalance within the part that is bearing measured. Together with the phase information, the machine can determine where to remove and where to add weight to balance its parts.

 Applications of a balancing machine

The balancing machines are capable of supporting different types of applications. They can be used in repair shops, for end users, overhaul and OEMs.  The balancing machine ranges from vertical balancing machines, horizontal balancing machines and side spindle balancing machines. Their size goes from the small desktop balancers to the optional floor-mounted based or large floor model machine.

While choosing the best balancing machines, you have to check the following:

  • It should have adjustable supports with interchangeable tooling that helps to run many rotor types using one balancing machine.
  • It should be extremely durable to measure the components while ensuring the longevity of the service with the continuation of the reliable reading.
  • It needs a standard software package that offers simple operation for set-up with understandable displays while simplifying the selections.
  • Automatic or manual measure cycles which support different production requirements are important.
  • Automatic or manual correction options with the supporting software that clearly displays the amount and the place where there is imbalance are essential.

There are many applications where you will need balancing machines like blade balancing, camshaft gear balancing, piston balancing, motor balancing, roll balancing, and shaft balancing, among others.

Driveshaft balancing

When the driveshaft is thought to be off balance, then you should check if there is a missing balance weight, broken welds or paint or dirt which may be causing an imbalance for the driveshaft.  You should inspect the U-Joints and the clamps to check for looseness and wear and replace them when needed. When the driveshaft has been bent, then it will require replacement. You can use a balancing machine to measure what the problem is with the driveshaft.

Tire balancing machine

Tire balancing is also called tire imbalance or tire unbalance. It is used to describe the distribution of mass within an automobile tire or the entire wheel, and this includes the rim on which it has been attached. When the wheel rotates, the asymmetric nature of the mass will cause it to hop or wobble, and this may lead to a disturbance in lateral and vertical vibrations. It may lead to wobbling of the steering wheel, or it may affect an entire vehicle. A ride disturbance because of unbalancing will increase as the speed increases, and the vehicle suspension may become excited because of unbalanced forces if the speed of the wheel has reached a point of rotating frequency that equals the resonant frequency of the suspension.  To know the status of the tires, a balancing machine is used, and it helps to correct weights which are applied for counteracting the combined effect of the wheel and tire unbalance.

Engine balancing

Engine balancing refers to all factors in the engine tuning, production and design together with maintenance and operation of an engine that benefits when the engine is balanced well. The consideration of balancing is based on the operation and structural operation elements of an engine, the performance and longevity of an engine, and the efficiency and power of an engine.

Dynamic balance

Static balance is used to refer to the ability of stationary objects to balance. However, dynamic balance, on the other hand, is the ability of something to balance while in motion or when it is switching between two positions.

Balancing equipment

A static balancing machine does not have a rotating machine which will rotate to take the measurements. Instead, it rests on the bearing, and the parts rest vertically at the geometric center.

A blade balancing machine tries to balance all the parts in the assembly. It can require only minimal correction afterward. The blade balancers are needed for different parts like turbines, propellers, and fans.

A portable balancing machine is used to balance different parts that cannot be taken apart easily.  They are used on the parts that are mostly in operation like motors, pumps, and turbines.

What is a balancing machine?

The balancing machines are found in two types: soft bearing or hard bearing.  However, the difference exists in the suspension and not with the bearings.

How does a balancing machine work?

A balancing machine works with a rotating part which rests on the bearing, and the vibration sensor is then attached to the suspension. With a soft bearing, the velocity sensor is then used. The sensor works through the fixed coil that generates the voltage proportional to vibration or velocity.
