Although gears are one of the oldest mechanical components, the technology of gear design and simulation still faces challenges and constant pressure to achieve improved designs with lower levels of noise and vibration suitable for longer operation time and/or higher power density.  RIT’s practical 3-day workshop is designed to bring you up to speed on advanced gear design and simulation, utilizing state-of-the-art computational tools for virtual generation of gears and application of tooth contact analysis (TCA) and finite element analysis (FEA).  Topics include: application of micro-geometry modifications to avoid edge contact and absorb errors of alignment, free-form design of gear tooth surfaces, evaluation of the loaded function of transmission errors and mesh stiffness as the main cause of noise and vibration during operation, compensation of errors of alignment caused by shaft deflections, and advanced design and simulation of different types of gear drives.

Who Should Attend

Engineers and qualified technicians involved in the design, analysis, manufacture, or application of gear drives will benefit the most from this state-of-the-art workshop.  Industries include automotive, wind-energy, aircraft, general manufacturing, and gear manufacturers.

Need for This Workshop

The process of gear design is extremely broad, based on simplified models and analytical equations with many empirical parameters.  RIT’s workshop offers a very different approach to gear design and analysis focused on the virtual generation of gear geometry, the application of micro-geometry modifications, and the evaluation of mechanical performance through tooth contact analysis (TCA) and finite element analysis (FEA).  The workshop will also provide participants with new approaches to gear design and simulation of gear drives that will improve advance participants’ current practices.

About the Instructor

Alfonso Fuentes Aznar headshot

Dr. Alfonso Fuentes has more than twenty years of experience studying gear generation and micro-geometry modifications, including the development of computational tools that gear designers need to improve existing designs or develop new designs with superior conditions of meshing and contact.  He is currently developing improved gear transmissions for the helicopter, marine, and automotive industries, while also pioneering enhanced design tools such as IGD (Integrated Gear Design) software, which is used for all types of gears.  This software serves as the ultimate tool for advanced gear design, analysis, and simulation.

Several awards recognize his research efforts including a NASA Tech Brief Award in 2004 for the development of a technology, “New geometry of Face Worms Gear Drives with Conical and Cylindrical Worms,” and the Thomas Bernard Hall Prize in 2001 granted by the Institution of Mechanical Engineers of London to authors of outstanding papers dealing with invention, design, or research in Mechanical Engineering.  Dr. Fuentes has authored two books and more than a hundred publications. His co-authored book, Gear Geometry and Applied Theory, has been cited more than 2,500 times. Since 2015 he has been the gear and cam subject editor for the journal Mechanism and Machine Theory. 

Dr. Fuentes is also Director of the Gear Research Consortium at RIT.  Contact him at
