Prof. Gerhard Poll

Head of Mechanical Engineering Leibniz University Hannover

Diploma in Mechanical Engineering and Ph.D. at RWTH Aachen University with a thesis on traction in rolling contacts, finished in 1983. From 1984 until 1996 application engineer and project leader in research and product development at SKF GmbH in Schweinfurt, Germany, SKF Engineering and Research Center in Nieuwegein, The Netherlands and CR Industries in Elgin, Ill., USA.  Main focus: rolling element bearings and seals basic tribology, development and application. Since 1996: Professor and director of the Institute of Machine Design and Tribology at Leibniz University Hannover, Germany, with tribology, lubrication, rolling element bearings, seals, wind power drive trains as well as synchronisers, continuously variable transmissions and electrified drive trains for vehicles being major research topics.

Conference day II, Wednesday, 13 May 2020

Wednesday, May 13th, 2020

1:40 PM Possible root cause failures

• Premature RCF (WEC)
• Main shaft bearing lubrication and wear problems
• Methods for early detection of emerging damages

4:00 PM Root cause failures of wind turbine bearings in drivetrains

WT gearbox and generator failure rates are unacceptably high, particularly given the long downtime incurred per failure. There is evidence that bearing failures of the gearbox highspeed stage (HSS) and generator account for a significant proportion of these failures. What are the root causes of these failure data and how can a valuable ‘top down’ reliability analyses be of help?
• Identify potential causes
• Review existing documentation & machine data review
• Inspection and measurements
• Lubrication analysis
• Corrective action recommendations
• Root cause findings documentation
