Leonardo Helicopters’ 20-year, 650+ test campaign characterizing tooth-root bending fatigue strength across gear materials, heat treatments, and finishing processes (notably shot peening and superfinishing) to support aerospace gear design.




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 excerpt from Gear Technology Solutions explains how oversized cutter blade edge radii cause root interference in bevel gears, and how to select correct radii to avoid noise, flank damage, and tooth fracture.
.
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.
.
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.

When you talk with Jared Lyford, director of operations at Forest City Gear and the newly appointed president of the Rock River Valley Tooling & Machining Association (RRVTMA), it becomes clear very quickly: workforce development isn’t a program for him. It’s a calling—and one shaped by lived experience.

In conventional gear manufacturing, quality control is carried out for a number of pieces per batch. Most parts enter final gearbox assembly without any inspection. Among other things, this approach is based on two facts: measuring time is significantly longer than the machining time, and the limited measuring capacity available.

Heat Treat 2023 is the Heat Treating Society’s 32nd conference and expo for heat treating professionals featuring three days of face-to-face networking opportunities with approximately 200 heat treat exhibitors/companies. All the top heat-treating companies will offer the latest research and industry insights during more than 100 technical programs. This year’s show includes a VIP-guided industry tour, as well as student/emerging professionals initiatives, including free college student registration, Fluxtrol Student Research Competition, and the ASM Heat Treating Society Strong Bar Student Competition. Heat Treat 2023 is colocated with Motion + Power Technology Expo 2023 with access to additional exhibitors. The event takes place October 17–19, 2023 at Huntington Place in Detroit.
The demand for double helical gears in planetary gear systems for engines in the civil aerospace industry is increasing. Innovative grinding processes and state-of-the-art technologies ensure precision, reduced weight, and improved cost efficiency. Learn how KAPP NILES reduced the gap width from 30 mm to 15 mm.
Discover four diagnostic enhancement tools that move RX® endothermic gas atmosphere generator operations from preventative to predictive maintenance. Learn how monitoring dew point by retort, comparing equal flow, tracking tube performance, and measuring outlet temperatures prevent costly failures while ensuring consistent, high-quality carrier gas production.
The right hob can make a measurable difference in gear production. Watch the video to see how Star SU combines advanced hob technology with application expertise to help manufacturers get more from every gear cutting operation.
The Intra SFTX twin-spindle single-flank testing system is engineered for advanced gear quality testing and NVH analysis of demanding e-drive gear applications. Combining Transmission Error (TE) and Torsional Acceleration (TA) measurements, it delivers fast, precise diagnostics and detailed order analysis, quickly identifies critical gear issues, enhances traceability, and helps prevent costly defects from reaching end-of-line (EOL) testing.
The 80PS Power Skiving and Hobbing Machine is specifically engineered for power skiving, hobbing, and profile milling of small internal and external gears. Configured specifically for the demands of humanoid robotic gear production, it delivers outstanding performance and process stability for gears used in strain wave, planetary, and cycloidal gearboxes, as well as other high-precision applications of comparable size — even when machining fine-pitch gears and thin-walled components.
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 countdown is officially on, and this one comes with a milestone attached. In just one year, the gear and bearing industries return to Detroit for the Motion + Power Technology Expo (MPT Expo), and 2027 marks the show’s 40th anniversary. It started in 1985 as Gear Expo, back when exhibitors worked out of tabletop displays rather than full booths. Four decades later, it’s still the one event where gear and bearing manufacturers, suppliers, and the OEMs who depend on them show up in the same room, at the same time.

At IMTS 2026, chip and coolant handling experts Jorgensen Conveyor and Filtration Solutions will highlight their expanded FlexFiltration coolant management systems that extend coolant life, enhance part finishes, and reduce maintenance procedures and costs. In Booth #338009, Jorgensen will feature complete, fully automated systems that showcases compact modular designs with advanced customization for integration versatility in coolant filtration and monitoring.
