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.
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 covering when and how individual bevel gear members can be replaced during gearbox service without changing the mating gear.
.
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.
.
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.

The way to increase production, especially with the largest gears, is to decrease nonproductive time with improved strategies.
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.
Gas carburizing has been around for a long time. One could argue that gas carburizing is the most common heat treating process. Heat treaters performing gas carburizing are often characterized by a dirty environment, hazy surroundings, and that “smell.” While the product quality may be acceptable, gas carburized parts do come with some challenges, like excessive intergranular oxidation (IGO) or intergranular attack (IGA), which is often ground off. Low-pressure carburizing (LPC) has proven to be a much cleaner and very capable alternative process. Most furnace companies have combined LPC with high pressure gas quenching, which moved carburizing from the dark back room to a relatively “clean room” environment. However, there is still a strong need for oil quenching, which is the common feature of the long used standard integral-quench (IQ) furnace.
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%.
Gear Profile Grinding Machine ZP 10 with automatic tool changer from Kapp Niles. The machine concept stands for maximum workpiece quality, flexibility and a long service life. The basic machines are equipped with a dresser, integrated measuring device, balancing unit and comprehensive software. The machines feature generously dimensioned rotary tables with electrical direct drive and large rotary table bores.
Gleason Corporation has appointed Bijal Thakkar as President and Chief Operating Officer, effective July 6, 2026. With Bijal Thakkar’s appointment, Gleason reinforces its commitment to long-term growth while remaining focused on delivering innovative solutions that help customers succeed in an increasingly dynamic global marketplace.
