Dontyne has invited several automotive companies to present applications to assess the suitability of non-involute technology. There are not always advantages over involute designs, but EV applications seem especially suited, and 15–25 percent power-density gains are typical. There are also consequential benefits, such as reduced gearbox housing and transport costs.
This paper presents a new analytical method using plate and disk mechanical models to calculate the gear body stiffness of face gear wheels, showing that stiffness decreases toward the outer radius—a behavior that conventional cylindrical gear approaches fail to capture.

This study investigates how manufacturing-related geometry deviations in the tooth root area affect gear bending strength calculations, demonstrating that accounting for measured tooth contours rather than nominal geometries is essential for accurate material comparisons in fatigue testing.

20NiMo9-7 alloy achieves up to 48 percent higher fatigue strength than conventional carburizing steels in the as-carburized condition, eliminating the need for shot peening and grinding in automotive gear applications.

An excerpt from Gear Technology Solutions by Dr. Hermann J. Stadtfeld exploring the mathematics behind conjugate bevel and hypoid gears—from the fundamental laws of gearing and the conditions for perfect conjugacy to why real-world power transmissions require deliberate crowning rather than theoretically exact conjugate designs.

Due to near-net shape production, additive-manufactured (AM) gears have a high potential to decrease costs and increase resource efficiency. The decreasing product life cycles as well as the increasing individualization of components demand high flexibility in manufacturing processes
For the research developed in this work, an existing simulation model of the generating gear grinding process based on a penetration calculation approach is used. Further, an extension of the model considering a realistic modeling of the grinding worm topography and the macro movements of the grinding worm during the process is presented. The result of the simulation is the microinteraction characteristics throughout
the grinding of the gear flank. In the end, the information about microinteraction characteristics obtained will be used for the calculation of force and energy in generating gear grinding.
The arrival of Gleason’s Hard Finishing Cell (HFC) in 2018 represented a paradigm shift in the way automotive transmission gears and gears for e-drives, could be produced in high volumes. Now, for the first time, 100 percent inspection of every gear, and every gear tooth was possible in-process, without impacting the high speeds at which these gears need to be hard finished. Identifying, and correcting for, conditions that create unacceptable noise behavior in these gears, on the fly, was finally a reality too.
Various in-situ methods can track realtime heat treatment response in bulk materials. This can aid material engineers in designing the most effective heat treatment procedures and processing methods. In-situ methods such as thermogravimetry (TG), differential thermal analysis (DTA), and dilatometry, offer capabilities to examine heat treatment behavior in real time, giving insight into the thermochemical mechanisms and the thermal behavior of steel.
Discover how next-generation bevel gear metrology combines flank form, waviness, surface quality, and root geometry analysis in a single automated inspection cycle. Advanced software and standard probes deliver faster measurements, deeper diagnostics, improved process control, and enhanced gear performance.
Deburring gears is dusty, repetitive, and hard to staff. The OB7 cobot from Productive Robotics automates it with quick setup and no programming required. Consistent finish on every part, built in the USA. See the full cobot deburring package and request a quote.
Gleason’s new line of high-performance QFS Quick-Flex Segmented Collets are designed for seamless integration with all major workholding systems. Manufactured to the highest standards, they provide exceptional concentricity, durability and clamping force. With their blue vulcanised clamping elements, QFS are a commitment to quality, offering run-out accuracy of ≤5 µm. Put them to the test.
TfG’s RGC 350 Radial Chamfering Machine from Machine Tool Builders produces defined, reproducible chamfers and ‘perfect’ teeth every time. The continuous, high-speed cutting process works wonders even on workpieces with interfering contours. What used to be slow, painful and expensive is now fast, painless, and perfect.
Gleason's Closed Loop System with robot or cobot loading now fully automates the measurement and correction process in gear production. Automatically prompting corrections on connected production machines, the GMSP series not only reduces human error in repetitive tasks, it also increases utilization of inspection equipment up to 90%.
At American Precision Gear, quality isn’t just a priority — it’s the foundation of everything they do. The shop specializes in high-precision miniature gears for aerospace, defense, and medical applications, where the strictest tolerances are non-negotiable. Helios Gear Products partnered with American Precision Gear to integrate the MZ 1000 D-Drive into their production.
The Society of Tribologists and Lubrication Engineers (STLE) — the technical society serving individuals, companies and organizations that comprise the tribology and lubrication engineering business sector — today announced that Steffen Bots, vice president of global sales & R&D at ADDINOL Lube Oil GmbH, in Leuna, Germany, assumes the role of 2026-2027 president for a one-year term beginning May 19.
HWR Workholding USA has announced that IMTS 2026 will feature the North American debut of two new products within its INOFlex family of flexible, high-performance 4-jaw chucks. The company will also be showcasing a comprehensive sampling of its full range of workholding solutions for turning and milling applications. Additionally, attendees who visit the company’s Booth #431579 in the West Building will receive a commemorative German-style beer boot pint glass.
