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.
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.
.
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.
.
Through loaded tooth contact analysis of two applications, this paper demonstrates that crown gears can match bevel gear load capacity while offering meaningful advantages in weight reduction, axial-force-free pinion mounting, and assembly simplicity.

This article describes a cloud-based process and machine component monitoring system called ARGUS. The term “swarm” is used for a large population of gear-grinding machines of individual and independent customers connected to the ARGUS system and the ARGUS cloud. These “swarm” machines permanently feed their anonymized process data into a common cloud database. Reishauer uses this database for big data analytics to discover patterns that indicate successful process and machine component behavior patterns worth integrating into the ARGUS algorithms and propagate them across the complete ARGUS customer base.
In the present paper, a spline-joint design and the extension of a back-to-back test rig were presented, which enable the testing of crowned spline-joints under high rotational speed, medium torque, high test temperature, and angular misalignments.
By understanding customers’ manufacturing and heat-treatment processes, Ipsen identifies pain points and develops IIoT and AI-driven solutions that improve operational efficiency.
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.
Marposs presents its latest innovations in precision measurement and quality at Control 2025. Marposs technologies support advanced manufacturing processes and ensure the highest standards of accuracy and reliability.
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.
