PRESENTER: Donald R. Houser, Professor Emeritus, Ohio State University, Department of Mechanical Engineering
Professor Emeritus Donald Houser is retired from the Faculty of the Department of Mechanical Engineering at Ohio State where he spent 35 years on the faculty. Dr. Houser is the founder of the Gear Dynamics and Gear Noise Research Laboratory (GearLab), an industrial research consortium with 45 participating companies. He has supervised over 120 graduate student theses and has consulted on gearing problems with over 60 companies. Professor Houser has over 150 gearing publications and is author of chapters on gear noise in the Dudleyâ€™s Gear Handbook (McGraw Hill, 1991 â€“ out of print) and the Noise and Vibration Handbook (Wiley, 2007). He is a fellow of the American Society of Mechanical Engineers (ASME) and recently received the Darle Dudley award from ASME. He currently is active on the following AGMA technical committees: Helical Gear Rating Committee, Bevel Gearing Committee, and the Sound and Vibration Committee.
WHO SHOULD ATTEND
PURPOSE AND DESCRIPTION:
This webinar will demonstrate techniques for using the gear microgeometry to minimize noise excitations and also to evaluate the gear contact stresses, bending stresses and tribological factors such as film thickness and flash temperature. The gear pair used in this study is the high speed ratio of the NREL-GRC wind turbine gearbox. In addition to the load distribution analysis, we shall explore ways of using load distribution analysis to come up with new macrogeometries that perform as well or better than the original design. Finally, a simple dynamic analysis of the gear set will be performed to observe the response of various natural frequencies to a transmission error excitation.
