Welcome to the RIT's Gear Research Laboratory

RIT's Gear Research Laboratory was established in 2015 by Dr. Alfonso Fuentes Aznar in the Department of Mechanical Engineering of the Kate Gleason College of Engineering. The Gear Research Laboratory at RIT, in collaboration with researchers at the Polytechnic University of Cartagena (UPCT) in Spain, is focused on the development of IGD - Integrated Gear Design - as the ultimate computer program for advanced gear design as well as analysis, optimization, and troubleshooting of gear drives.

IGD - Integrated Gear Design - is being developed thinking of both, gear design and gear manufacturing. The geometry of gears is obtained using the principles of the modern theory of gearing and the kinematics of the cutting tools exactly as in real production. A complete set of cutting processes and cutting tools are available for gear generation application. The evaluation of the obtained gear geometries is fast and inexpensive.  IGD implements a virtual gear generator that models any type of geometry and applies enhanced approaches of tooth contact analysis and finite element modeling.  Other tools included in IGD allow us to achieve the optimal design, as for example the module of free-form design for the application of micro-geometry modifications to the gear tooth surfaces or the backlash analysis based on actual geometry and contact analysis.

The Gear Research Lab is poised to contribute to Rochester's long tradition and recognized global leadership in gear design and manufacturing in support of our corporate partners and our community. We are also providing the technical education necessary to ensure the supply of a talented workforce of engineers to support the gear industry. We are always looking for new researchers and the establishment of corporate or academic partnerships. If you are interested in working or collaborating with us, please do not hesitate to contact us.


RIT's Gear Research Consortium welcomes Allison Transmission

RIT and the Gear Research Laboratory welcome Allison Transmission as a new member of the RIT's Gear Research Consortium. Allison Transmission is the world’s largest manufacturer of fully automatic transmissions for medium- and heavy-duty commercial vehicles and is a leader in hybrid-propulsion systems for city buses. Allison Transmission’s products are specified by more than 300 of the world's leading vehicle manufacturers and are used in a wide range of market sectors including bus, fire, construction, distribution, defense, and specialty applications.

Allison was founded in 1915 in Indianapolis, Indiana, where the company's global headquarters is still located. Allison Transmission has regional offices all over the world and manufacturing facilities in Indianapolis, Chennai, India, and Szentgotthárd, Hungary.

Celebrating the 10th anniversary of IGD – Integrated Gear Design

This month we celebrate the 10th anniversary of IGD - Integrated Gear Design. Thanks to everyone that have contributed in one way or another to make IGD a reference computer program for advanced gear design and simulation. It was fall of year 2009 when we started to work on this idea and we wrote the first lines of code of a computer program aimed to combine all the accumulated experience on the application of the theory of gearing and to make advanced gear design and simulation accessible to everyone.

Join us and learn about advanced design, simulation of meshing and stress analysis of gear drives

The workshop "Advanced Design, Simulation & Stress Analysis of Gear Drives" will be held for the first time at RIT Campus in Rochester, NY, on June 24-26, 2019. This practical 3-day workshop will 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).

Our latest research work has just been published in Mechanism and Machine Theory

Our latest research work entitled "Conjugated Action and Methods for Crowning in Face-Hobbed Spiral Bevel and Hypoid Gear Drives Through the Spirac System" has just been published in the Journal Mechanism and Machine Theory. In this work, an analytical method for derivation of basic machine-tool settings that allows the conjugated action in face-hobbed spiral bevel and hypoid gear drives is proposed. This approach is then used as starting point for investigation of further methods of crowning.

Dr. Fuentes selected as the KGCOE featured faculty for the RIT's 2017 faculty scholarship report

Dr. Alfonso Fuentes Aznar has been selected as the KGCOE featured faculty in the RIT's Faculty Scholarship report of 2017. The  RIT's annual scholarship report is intended to acknowledge the ever-growing body of work produced by the RIT faculty in a wide range of fields and formats. The 2017 faculty scholarship report is the eighth annual review highlighting RIT faculty publications, scholarly presentations, exhibits, performances, and fellowships for the year 2017. The featured faculty members in the RIT's scholarship report exemplify the teacher/scholar ideal and are models to their students and colleagues.

Remembering UIC Distinguished Professor Emeritus Faydor L. Litvin

The following paragraphs are extracts of the original post published at UIC web site: Celebrating the Life of Distinguished Professor Emeritus Faydor Litvin

On April 26, 2017, the scientific community of mechanical engineers worldwide lost a renowned scientist and educator who dedicated his life to the development of the modern theory of gearing and made enormous contributions to the development of the theory of mechanisms.

Professor Litvin had been recognized as an authority in kinematics and the theory of gearing. A whole epoch in the theory of gearing is concerned with the name of Professor Litvin. He is the author of one of the most fundamental and cited works in the field—a well-known monograph, The Theory of Gearing, which underwent six editions.

Born in Russia in 1914, Professor Litvin graduated from Leningrad Polytechnic Institute in 1937 with distinction. He defended his PhD in 1944, becoming a unique, self-educated PhD holder and later received his Doctor of Technical Science degree in 1954. From 1963, he served as department head and professor of mechanical engineering at the Institute of Precision Mechanics and Optics in Leningrad. He trained and supervised 100 PhD students (50 in Russia and, later, 50 in the U.S.) as well as visiting scholars from around the world. All of them went on to receive prominent teaching and research positions in the U.S., Italy, Spain, Russia, Bulgaria, Poland, Hungary, China, Taiwan, and Australia. With great pride, they consider themselves as belonging to the “elite school of Litvin".
