  • External Spur And Helical Gear Mesh Contact Analysis Video Training

    Includes Credits

    This online seminar will calculate and demonstrate the effect that shaft bending, torsional windup and tooth deflections have on loaded tooth contact on various configurations of parallel shaft spur and helical gearing. With the loaded tooth and shaft deflections identified in real life examples, tooth helix and profile modifications will be developed that, when properly manufactured and applied, will significantly improve loaded tooth mesh contact to support realistic load distribution factors used in rating of parallel shaft spur and helical gears. The process involves the application of commercially available software that models the loaded gear mesh in FEA. This evaluation and corrective action will promote optimization of power density with predictable fatigue life.

  • Coronavirus, the economy and key machinery markets – current perspectives

    The crisis triggered by the expanding footprint of the coronavirus globally and within North America has few precedents. Cross checks to prior recessions in 2008-09, 1981-82, and even the depression triggered by the Spanish flu of 1918-1919 serve to give some guidance, but crude. The economy and the outlook for key machinery and capital goods markets is fluid and changing daily. Jim Meil will give call participants an update on the current situation and scenarios for what may lie ahead for 2020 and beyond.

  • The End of the World...and Other Opportunities Webinar

    The era of globalization is dependent upon freedom of the seas, American security overwatch, and a global consumer base — all of which were coming to an end before coronavirus erupted upon the world. The pre-coronavirus pace of change, already among the most rapid in history, has now accelerated greatly. Join us as Peter Zeihan walks us through the causes and consequences, the actions and inactions, which have made and are unmaking our world.

  • Gear Failure Analysis - November 10-12, 2020

    Explore gear failure analysis in this hands-on seminar where students not only see slides of failed gears but can hold and examine those same field samples close up. Use of a microscope to examine field samples.

  • Fundamentals of Gear Design and Analysis - August 11-13, 2020

    Gain a solid and fundamental understanding of gear geometry, types and arrangements, and design principles. Starting with the basic definitions of gears, conjugate motion, and the Laws of Gearing, learn the tools needed to understand the inter-relation and coordinated motion operating within gear pairs and multi-gear trains. Basic gear system design process and gear measurement and inspection techniques will also be explained. In addition, the fundamentals of understanding the step-wise process of working through the iterative design process required to generate a gear pair will be reviewed. Learn the steps and issues involved in design refinement and some manufacturing considerations. An explanation of basic gear measurement techniques, how measurement equipment and test machines implement these techniques, and how to interpret the results from these basic measurements will also be covered.

  • Additive Manufacturing Technologies for Gears

    The American Gear Manufacturers Association (AGMA) announces the publication of an emerging technology document, Additive Manufacturing Technologies for Gears. This paper is part of the AGMA Emerging Technology Committee’s commitment to bring information on disruptive technologies to the AGMA membership. Kirk Rogers, PhD, Senior ADDvisorSM of The Barnes Group Advisors was brought on to author the paper with significant input from members of both the AGMA Emerging Technology Sub-committees on 3D Metal Printing and New Materials. Kirk Rogers, PhD, will provide an overview of the paper and answer your questions during this webinar. Sign up today to hear it from the author how this technology can affect you.

  • Basic Gear Inspection for Operators - November 4-5, 2020

    Learn the common, current and basics of the tools and techniques used to measure and inspect gears. There are four main categories by which a gear evaluated and classified. Gear design, manufacture and inspection are based on numerical scale that defines gear quality. The methodology to measure and techniques required to quantify quality of a gear tooth form will be thoroughly investigated and explained. It is often stated that quality cannot be inspected into the part, however inspection can tell us what to do to correct many issues.

  • Gear Systems Design for Minimum Noise - December 1-3, 2020

    The need for noise control and its relation to gear drive design will be discussed. The general nature of noise and its measurement will be examined, with particular emphasis on terminology standards, and units of measurement appropriate to gear technology. Gear noise, per se, is seldom heard by and observer. The mechanism by which observer noticed noise is generated and transmitted will be defined, described, discussed. Before attempting to solve a noise problem with an existing unit or beginning the design of a new unit, the nature of the noise must be defined. Both experimental and analytical methods will be covered, with particular emphasis on application rather than theory. The many factors that influence the noise produced by a gear system will be discussed. The relative effects of each factor will be studied qualitatively. Factors to be considered include gear tooth geometry and accuracy, speed, materials, housing design, bearing type, gear type, air entrapment, root clearance, interference alignment, surface finish, and phasing. Although, ideally, the designer should solve noise problems on the drawing board, in the real world this sometimes does not occur. Various techniques that can reduce the noise level of existing gear systems without requiring major hardware replacement will be presented and discussed. Included in the discussion will be enclosures, absorbers, dissipative dampers, isolators (gearbox and gear blank), and impulse phasing. Although solutions to particular student-furnished noise problems cannot be promised, you will be encouraged to raise questions for class discussion.
