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.
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 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.

Water spray quenching achieves heat transfer coefficients up to 4,000 W/(m²K)—nearly double conventional oil quenching rates—enabling potential material substitution and tailored quench intensity for complex gear components.

This article demonstrates why bevel gears are designed with a zero sum of profile shifts—showing that independent shifts merely replicate what a modified pressure angle already achieves—and explains the practical benefits of using conical generating gears for tooth profile crowning.

For cylindrical gears, speed-increasing transmission stages are well known, and regarding profile shift, preferred pressure angles, and helix angles a set of rules applies, which is not much different from the rules for speed reducers. It is important to acknowledge that basically, a speed increaser has to be designed just like a speed reducer, but then the gear with the lower number of teeth is the output. Of course, the torque and the speed of the gear with the lower number of teeth (output) and the gear with the higher number of teeth (input) must be the same as if this transmission was used as a speed reducer. In the case of straight bevel gears, spiral bevel gears, and hypoid gears the same rules apply with some additions. Spiral bevel gears have many applications as speed increasers.
The way to increase production, especially with the largest gears, is to decrease nonproductive time with improved strategies.
As the gear and power transmission industries evolve, companies worldwide face a critical challenge: how to ensure the workforce is skilled, prepared, and ready to tackle increasingly complex manufacturing processes. From digital manufacturing and automation to generational turnover, the demand for technically proficient employees has never been higher. In response, the Motion + Power Technology Association (MPMA) redeveloped its Workforce Training Series, modernizing its most popular on-demand courses with updated content, high-quality media, and a flexible, self-paced delivery model.
Quality control, EV components, energy consumption and material influences are just a handful of topics being discussed in heat treating today. New heat treat methods and global trends will be the topic of conversation later this year at Heat Treat 2023. Here’s a round-up of some stories circulating across key market segments.
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%.
The Horsburgh & Scott engineering team has over 135 years of experience designing, manufacturing and maintaining gearboxes in heavy-duty applications around the world. They have proven design standards for gearboxes up to 5,000 hp and 4 million ft-lbs. with speeds from 0.5 to 3,600 rpm. If they don’t have a standard gearbox to meet customer's needs, they can design a custom gearbox for a specific application.
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.
