This year, the AGMA's Fall Technical Meeting will be held in Chicago on November 2-3, 2021. Although some presentations will be pre-recorded because of continued Covid travel restrictions, most presentations will be in-person. The AGMA's Fall Technical Meeting brings together top researchers from across the globe who will provide the latest information on their peer-reviewed gear industry research.

Dr. Fuentes will be attending the 2021 AGMA's Fall Technical Meeting and presenting the paper entitled "Investigation of the Effect of Application of Non-Conventional Root Profiles for Reduction of Bending Stresses in Helical Gear Drives" in Session 1 on Tuesday, November 2, 2021.

Abstract:

Studies of non-conventional root profiles have mainly used finite element models in which the load is applied at the highest point of single tooth contact. The adjacent pair of teeth, when they carry part of the load, cause compressive stresses on the root area. This study will provide the variation of the alternate and mean range normal stresses on the root surface in the longitudinal direction of the gear teeth for tooth root profiles based on Hermite, elliptical, and Bézier curves and their comparison in terms of the mentioned stresses with those obtained for conventional root profiles. Such variation will be obtained for two cycles of meshing by considering finite element models with five pairs of teeth so that the effect of load sharing between adjacent pairs of teeth is considered.

IGD – Integrated Gear Design – continues growing every day. IGD version 3.7 comprises more than 1.4 million lines of code distributed in 1,321 files. It provides solutions for advanced gear design and simulation of 22 different types of gear drives, based on 115 different geometries, that make use of 16 cutting tools, and simulated by the application of 6 different tools for analysis that includes TCA, FE modeling, optimization, geometry comparison, gerotor pump analysis, and reverse engineering.

IGD has become the ultimate computational tool for the advanced design and simulation of gear drives. IGD includes a virtual gear generator of almost any type of gear. The virtual gear generator uses the geometry of the cutting tool and the kinematics of the manufacturing process to get the most accurate geometry of the gears. By using the freeform design module, surface modifications can be added and studied to localize the contact pattern and provide favorable functions of transmission errors that will contribute to reducing noise and vibration of the gear drive. The unique approach for tooth contact analysis based on the consideration of three pairs of contacting teeth allows detecting possible issues with the continuity of the process of meshing or loading sharing between consecutive pairs of teeth. Finite element models fully parametrized can be exported to main general-purpose computer programs (ABAQUS or ANSYS) for stress analysis. The finite element models may include shafts and bearings to determine errors of alignment under load that can be easily compensated by the surface modifications computed within IGD. Other simulation features include the simulation of noise and vibration excited by the loaded functions of transmission errors, variation of the meshing stiffness during the process of meshing, determination of friction power losses, efficiency, and heat generated, as well as the generation of solid models of the gears and gearset assembly for external gear simulation or 3D printing.

IGD is currently being used by the members of the RIT’s Gear Research Consortium and developed to meet their needs of advanced gear design and simulation. Do not hesitate to contact us to learn more about IGD and our RIT’s Gear Research Consortium.

RIT and the Gear Research Laboratory welcome EGILE and its HIGH PRECISION MECHANICS Division (DMP) as a new member of the RIT's Gear Research Consortium. EGILE is a company with 30 years of history, committed to creating impact through products and solutions of high value in sectors where extreme precision is a fundamental requirement. The high Precision Division of EGILE is composed of five business units, serving high-critical areas, such as the aerospace and security sectors, large scientific infrastructure and equipment, the packaging sector and thin sheet metal processing.

The High Precision Mechanics Division of EGILE covers the complete cycle of high precision machining, from engineering and design, to manufacturing. They design, develop, and manufacture components for the aeronautic and security sector such us engines, aircraft transmission systems, landing gear components, and actuation systems for leading aeronautical companies, through three specialized business units: AEROTRANSMISSION, AEROENGINES, and AEROSYSTEMS. They also develop high-precision mechanical solutions for the scientific and aerospace sectors, through the EXTREME PRECISION unit, as well as complete, easy open-end conversion systems for the food metal container section (CAN TOOLING unit).

EGILE and its High Precision Mechanics Division is located in Mendaro, Spain, in the heart of a territory with a long industrial tradition. In 2018, their turnover was around 24 M-Euros, exporting over 50% of his production. The company has more than 270 employees and invests 15% of the turnover in Research, Development, and Innovation (R+D+i). They are part of the Egile Corporation, a diversified industrial and technological group, with more than 350 employees.

We are looking forward to having a very long and fruitful collaboration with EGILE. Their vision to apply leading-edge technologies to put in the market high-value products, services, and solutions has already placed them as a reference leading company in all their business areas. We are honored to have EGILE as a member of the RIT's Gear Research Consortium.
