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.

Overall developments and widespread public awareness of man-made climate change are transforming the way people think. The awareness has inspired a shift towards a more ecologically sustainable way of life. Driven by policymaking and technological innovation, ambitious efforts are underway to reduce greenhouse gas emissions to curb the rise in average temperatures. A key focus of these efforts is the mobility sector.
Different component characteristics in electric vehicles lead to higher noise and load requirements in the automotive industry. E-mobility—to a certain degree—is changing how gear analysis and inspection is carried out. Dissecting noise issues in gears and gearboxes requires an analytical approach like a detective. The problem could stem from the design itself, tolerancing or tip/root relief issues, tooth flank form deviations like waviness or perhaps crowning issues that directly impact noise. Every aspect of gear production needs to be examined to provide the most accurate results.
The roots of heat-treating run deep within ASM (American Society for Materials) International, as its society was founded in Detroit in 1913 as The Steel Treaters Club. The heat-treating constituency of ASM created the Heat Treating Society (HTS) to provide focused leadership, communications, and service development to its network of worldwide membership of captive and commercial heat treaters, equipment manufacturers, researchers, governments, and technicians. To discuss Heat Treat 2023, the 32nd annual HTS Conference and Exhibition, Gear
Technology took a moment to catch up with conference chair Andrew Banka, vice president of Airflow Sciences Corporation. Heat Treat 2023 is colocated with IMAT and Motion + Power Technology Expo in Detroit, October 17–19.
