The automotive industry and its suppliers are undergoing profound structural change. Electrification, volatile markets and geopolitical instability, along with increasingly intense global competition, are creating high costs and innovation pressures across the entire value chain. These developments not only affect the general drivetrain components but also rotor shafts for electric motors, which combine high functional density with demanding manufacturing and quality requirements. Recent restructuring efforts, plant closures and bankruptcies have highlighted the need to critically reassess existing manufacturing concepts, especially for components such as rotor shafts with integrated functional elements. For automotive suppliers, technological capability and cost efficiency are no longer the only priorities; process robustness and investment security are increasingly moving into focus. New manufacturing solutions must not only be technically convincing, but also enable a substantial reduction in manufacturing costs, energy consumption, the associated CO2 emissions and process complexity (Refs. 1,2).
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.

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.

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.
.
A technical overview of the three principal face couplings (Hirth, Coniflex, and Curvic), comparing their tooth geometries, self-centering behavior, and Gleason’s cutting and grinding processes for manufacturing them.

Variable loads resulting from a working process, starting process, or operation near a critical speed will cause varying stresses at the gear teeth of a drive system. The magnitude and frequency of these loads depend upon the driven machine, the motor, the dynamic mass elastic properties of the system, and other effects.
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.
Complete inspection of gear surface finishes at the submicron level became a reality with the introduction of Gleason’s 300GMS nano, in 2022. The new system ushered in an exciting new era in gear inspection. For the first time, producers of EV transmission gears, and gears for other applications requiring very tight tolerances and low noise requirements, could quickly inspect surface finishes and perform extremely reliable noise analysis at submicron levels—benefits that were almost impossible to achieve just a few years ago.
Press quenching is a tried-and-true process for the controlled hardening of flat, circular close tolerance parts. The process ensures good dimensional control and uniform hardening, thus allowing for seamless processing post heat treatment.

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.
At Gear Headquarters, quality is the foundation of everything they do. Based in Kansas City, the shop manufactures spur, helical, double-helical, herringbone, bevel, internal, spline, and worm gears, sprockets, and timing belt pulleys.
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.
EcoCortec, the European subsidiary of Cortec Corporation, developed two certified compostable packaging films for heavy-duty industrial use: EcoShrink and EcoWrap. Manufactured at its facility in Croatia, these films serve as direct replacements for conventional polyethylene. They allow operations teams to maintain pallet load stability and meet environmental targets using their existing wrapping equipment and packaging workflows.
