GEARS
Every wind turbine gearbox overhauled here undergoes a rigorous test procedure of around eight hours’ duration before being released to the customer. The Nottingham site houses the only purpose- built wind turbine gearbox validation test rig in the UK, designed for partial load testing of gearboxes from turbines of up to approximately 2.4 MW generating capacity.
TEST RIG
The test rig is adaptable to different size gearboxes and capable of delivering up to 60,000 Nm of torque via a slave gearbox and output motor. The equipment can analyse oil flow and pressure, gearbox temperature, tooth contact pattern, and noise and vibration profiles. Thermal imaging is used to ensure that there are no local hot spots in the gearbox. Current draw, temperature, vibration and torque figures are recorded on the test rig’s human-machine interface (HMI) panel and a fully automated system collects all data with a logging frequency of at least 10 Hz.
Cleanliness of the gearbox oil is a critical factor in component longevity. The oil filtering unit checks for correct oil flow and filters oil down to at least 14/11 cleanliness code as defined by the ISO4406:1999 standard, ensuring that the gearbox is free of any particulate contaminants prior to despatch.
EXPERTS IN WIND TURBINE GEARBOX DESIGN AND MANUFACTURE In 2011, ZF Friedrichshafen AG acquired Hansen Transmissions International NV, the global leader in wind turbine gearbox manufacturing. Headquartered in Lommel, Belgium, Hansen now trades as ZF Wind Power, adding its wind turbine expertise to ZF’s long-established competencies in driveline technology.
