Summary of Expertise: Listed with other top experts in: 
HELICAL GEAR DESIGN; SPUR GEAR DESIGN; GEAR TOOTH. Expert has extensive experience in the design and analysis of spur and helical gears. He is the author of the computer programs GEARCALC and AGMA218, which are widely used by the gear industry for designing and rating spur and helical gears. He is active in several American Gear Manufacturers Association (AGMA) technical committees and has contributed to many of the design and rating methods used by the AGMA. These include the methods for calculating I and J factors (AGMA 908-B89), methods for calculating lubricant film thickness and contact temperature (Appendix A, AGMA 2001-B88), and "A Rational Procedure for the Preliminary Design of Minimum Volume Gears" (AGMA 901-A92).

GEAR LUBRICATION; GEAR WEAR; GEAR FATIGUE. Expert is knowledgeable of all aspects of gear lubrication including specifying, monitoring, maintaining, and analyzing gear lubricants. He is the author of "Friction, Lubrication, and Wear of Gears." He is also the author of the computer program SCORING+, which is widely used by the gear industry for calculating lubricant film thickness and contact temperature for predicting the probability of wear and scuffing in spur and helical gears. He has conducted fundamental research in Hertzian subsurface fatigue and polishing wear.

GEAR FAILURE ANALYSIS. Expert is an expert in gear failure analysis. He has determined the mode and cause of gear failures in a wide variety of industrial applications including iron ore grinding mills, cement mills, wind turbines, hydroturbines, wastewater treatment plants, aluminum rolling mills, radar drives, off-road vehicles, wheel chair drives, conveyor drives, computer disk drives, locomotive blower drives, and many more. He presents seminars on conducting gear failure analysis in the field and on gear failure photography.

Expert heads his own gear consulting firm, GEARTECH, and is founder of GEARTECH Software, Inc. He has over 50 years of industrial experience. He has been a consultant to the gear industry for the past 37 years and to over 50 wind turbine manufacturers, purchasers, operators, and researchers. He has taught courses in material science, fracture mechanics, vibration, and machine design at San Francisco State University and the University of California at Berkeley. He presented numerous seminars on design, analysis, lubrication, and failure analysis of gears and bearings to professional societies, technical schools, and the gear, bearing, and lubrication industries. He is a graduate of the University of California at Berkeley and holds BS and MS degrees in Mechanical Engineering and a Master of Engineering degree in structural dynamics. Expert is a member of several AGMA Committees including the AGMA Gear Rating Committee, AGMA/AWEA Wind Turbine Committee, ASM International, ASME Power Transmission and Gearing Committee, STLE, NREL GRC, and the Montana Society of Engineers. Expert has published over 80 articles on design, analysis, and application of gears, and is the author of three widely-used computer programs for design and analysis of gears. He is technical editor for GEAR TECHNOLOGY and STLE Tribology Transactions. He is recipient of the AGMA TDEC Award, the AGMA E.P. Connell Award, the AGMA Lifetime Achievement Award, the STLE Wilbur Deutch Memorial Award, the STLE Edmond E. Bisson Award, and the AWEA Technical Achievement Award.
