This a wind turbine gear that we manufactured with final inspection including Barkhausen noise measurement.
Barkhausen Noise is a micro-magnetic technique based on the magnetisation characteristics of ferromagnetic materials and is sensitive to changes in microstructure and applied or residual stress. The analysis method is non-destructive, quick and easy to apply and has proved to be extremely valuable.
Many of our gears are used in high horse power engines which drive generator sets.
Modern engines are mostly diesel and have high power density and improved cleanliness.
They are also used in land fill sites where they are powered on waste gas.
