Gears Have to Engage

June 12, 2024

A single gear, by itself, doesn’t do much good. No matter how brilliant its design or how superb its quality, it has to mesh with another gear to achieve anything useful. The transfer of torque, the change of direction and the increase or reduction of rotational speed only occur when two or more gears come together. The same is true of you.

Measuring Demands Today

Gaging evolves for precision, productivity, ergonomics and more

June 12, 2024

For precision measuring, skilled machinists, toolmakers, and inspectors must have accurate tools and gages, produced from quality materials, carefully manufactured, and rigidly inspected, to ensure lasting dependability. Gages have evolved throughout the years beginning with mechanical, then electronic models, and now convenient wireless electronic versions have come on the scene. Each type has an important place in today’s quality control and inspection processes.

Preventing Corrosion in Gears

Nanocomposite Coatings

A new approach to reducing wear, friction, and corrosion

June 12, 2024

Olivia Fey and Mike Greenwald

Thanks to advancements in material science and chemistry, particularly in nanoscience, a new solution has emerged: nanocomposite coatings, more broadly referred to as thin-film coatings. But how did we arrive at this point in coating development? As with many technologies, war highlighted the need for more advanced coating development eventually leading to nanocomposite coatings.

Optical Metrology for Evaluating Gear Noise

Klingelnberg looks at changing demands in automotive applications

June 12, 2024

Markus Finkeldey

When electric drives are used in vehicles, the masking effect of an internal combustion engine disappears, allowing the noise behavior of the transmission to take center stage. At the same time, peak power and torque increase, engine speeds increase, and power must be transferred optimally in both directions due to the regenerative braking system. Conventional design parameters remain important, however: The build space is limited, durability must not be compromised, and the product must still be cost-efficient. Optical metrology as part of a hybrid measurement concept helps to overcome all these challenges.

Nano-Level Gear Inspection Goes Smaller

With the 175GMS nano, Gleason brings submicron-level inspection capabilities to smaller gears, helping ensure minimal noise, greater precision, and longer life

June 12, 2024

Klaus Deininger

Complete inspection of gear surface finishes at the submicron level became a reality with the introduction of Gleason’s 300GMS nano, in 2022. The new system ushered in an exciting new era in gear inspection. For the first time, producers of EV transmission gears, and gears for other applications requiring very tight tolerances and low noise requirements, could quickly inspect surface finishes and perform extremely reliable noise analysis at submicron levels—benefits that were almost impossible to achieve just a few years ago.

Nonlinear Analysis of Gear-Fatigue-Damage Under Variable Load

June 12, 2024

Daniel Vietze M.Sc., Dr.-Ing. Josef Pellkofer, and Prof. Dr.-Ing. Karsten Stahl

This paper presents a comparison of the linear and nonlinear approaches for damage accumulation of tooth root breakage damage of gears. In the beginning, the theoretical fundamentals of damage accumulation are presented compactly. To compare the suitability of the methods an extensive set of experimental data is presented at first. The data is evaluated with both the linear and the nonlinear approach and the results are compared. For the linear approach, the method according to Miner and Palmgren is applied. For the nonlinear approach, the method developed by Subramanyan is used. The objective of this evaluation is to assess if the more complex method yields a potential benefit for a more accurate service life prediction of gears.

Immersive Engineering

Siemens and Sony collaborate on spatial content creation system

June 12, 2024

Engineers Assemble. If you’re a product engineer in charge of designing the latest and greatest manufacturing creations, it’s officially “Tony Stark” time. If Philip K. Dick is more your speed over the Marvel Cinematic Universe, than how about “Tom Cruise” time in Minority Report? Siemens and Sony recently introduced a solution that combines the Siemens Xcelerator portfolio with Sony’s new XR head-mounted display (HMD), SRH-S1—designed using Siemens’ own NX software—insert chicken vs. egg debate here.

AGMA Technical Committee Update

New Committee Restructuring—Version 2!

June 12, 2024

In 2023, the Technical Division Executive Committee (TDEC) worked on a technical committee restructuring that replaced the standing, topic-specific committees with working groups, which would focus only on an active project and fold when the project was completed. Due to feedback received on the change, the TDEC took a step back and re-evaluated the restructuring. This led to a new committee-based structure that takes the good parts of project working groups and merges them with the good parts of technical committees. The committees are consolidated and include sub-working groups to perform the work on information sheets and standards.

Crossroads of Creativity and Manufacturing

June 12, 2024

Mary Ellen Doran

I fly out west to Los Angeles later this month. It will mark the fourth time AGMA will provide a curated tour on the RAPID+TCT show floor. Each year brings more clarity on developed technologies, I am always looking for one or two tweaks that move the needle on the next possibility for additive manufacturing to impact traditional manufacturing processes. Are we looking for mass-produced 3D metal gears? The short answer is: no. But we are always watching indicators that may change that answer.
