Join Gleason's special online event to learn about the design, manufacturing, and inspection of e-Drive gears. The three-day event features one topic per day addressing the specific requirements and challenges of e-Drive transmission manufacture, with particular attention to minimizing gear noise.

The e-Drive Days are the perfect experience for newcomers and experts alike, showcasing the latest developments in design, simulation, cutting, and hard finishing, as well as suitable inspection and analysis tools to achieve the most efficient and quiet gears.

Day 1—March 14, 2023: e-Drive Gearbox Design and Optimization, 60 min

High rpm’s, reversal of load direction, low vibration excitation, high contact ratios, deformed housings ... the design, optimization, and service life calculation of gears for e-drives is a world of its own. Experience how individual requirements can be covered by the choice and variation of gear geometry, including macro geometry, modifications, and manufacturing deviations, and learn about the peculiarities of strength calculation in case of frequent changes in torque direction with torque-time series measured from test rigs. In addition, the calculation of the noise excitation within the drive train is important for NVH analysis and optimization of the gearbox. KISSsoft results will be shared with the multibody simulation program RecurDyn to facilitate a system response of the housing in form of an airborne sound as a base for further optimization.

Day 2—March 15, 2023: Manufacturing of e-Drive Gears, 70 min

e-Drive transmissions are different from conventional transmissions, creating new challenges for manufacturing processes. This presentation showcases processes for soft machining and hard finishing of typical e-drive transmission gears. Featured processes are hobbing, chamfer cutting, shaping, Power Skiving, threaded wheel grinding, and gear honing, including technology updates for hard Power Skiving of internal gears, polish grinding, and Combi Honing. Regarding the manufacturing of differential bevel gears, we discuss the Coniflex Plus cutting process to achieve greatly reduced bending and surface stresses with improved NVH characteristics.

Day 3—March 16, 2023: In-Process Inspection and Gear Noise Analysis, 60 min

Gear noise is an important challenge in automotive e-Drive and other applications, asking for extremely demanding gear characteristics. Understanding the origin of gear noise and tracing critical gear noise to its sources is the base for measures to counteract and minimize gear noise. This live webinar features state-of-the-art in-process inspection technology and the corresponding analysis tools including Gleason’s “Advanced Waviness Analysis” to detect and minimize noise emissions in e-Drive transmissions.
