What is Balancing?
When rotating or reciprocating components, such as driveshafts and clutch assemblies, are not completely balanced, vibrations can occur, causing mechanical stress – potentially leading to damage or failure. Balancing is the process of designing or modifying components so this unbalance is reduced or eliminated.
There are three types of unbalance:
- Static unbalance – is where the mass axis is displaced only parallel to the shaft axis. The unbalance is corrected only in one axial plane.
- Couple unbalance – is where the mass axis intersects the running axis.
- Dynamic unbalance – is where the mass axis is not coincidental with the rotational axis. This unbalance is usually a combination of static and couple unbalance and is corrected in two planes.
A balancing machine pinpoints the exact location and mass of any unbalance, so that excess material can be removed by drilling, milling, etc., from a “heavy” position on the component, or added to a “light” position by bolting or welding on balance weights. BPG balancing machines are so sensitive that they can identify a mass axis that is only 0.001mm off the running axis.
Balancers for All Applications
BPG offers a full range of high-specification horizontal, vertical and custom-designed machines. These systems can be either measurement only or include the option of manual or automatic unbalance correction. Our industrial balancing systems cater to every industry, including fans, pumps, armatures, locomotive components, rolls and virtually every rotating component.
Core markets for BPG balancing systems include aftermarket high production automotive, aircraft, energy, shipbuilding, mining, metallurgical, ventilation, paper and agricultural.
Balancers for the Automotive Industry
For automotive OEM and Tier I customers, as well as commercial vehicle and off-highway vehicle components, BPG supplies balancers for demanding high production environments. Solutions include balancing of propshafts, axles, crankshafts, turbos, brake rotors, transmissions, clutch parts, tire and wheel, damper pullies, and superchargers. All of our systems are highly accurate and repeatable for incredibly fast cycle times, exceeding all capability studies, and our systems are easily serviceable and highly reliable, backed by local support at all global locations.
BPG aerospace balancers offer a state of the art experience with the smallest possible footprint. Our vertical balancers for turbine wheels and horizontal balancers for turbine shafts and complete assemblies consist of special hard suspensions.
Balancers for Commercial Vehicle & Off-Highway Components
Offering a range of manual and automatic balancing machines for CV and off-highway vehicle components, we understand that increased component mass doesn’t mean we can compromise on our machine accuracy or functionality. We specialize in machines for propshafts, crankshafts, clutches, flywheels, pullies, turbochargers, plus more.
We engineer and manufacture highly accurate and efficient aftermarket balancers for the automotive industry, including dual mass flywheels, driveshafts, crankshafts, and clutches. Permanent calibration and rotor-specific calibration is a standard in our aftermarket crankshaft and clutch balancing systems. Our dual mass flywheel and clutch balancers utilize the latest rotating speed measuring systems.
