Design of e-Drive Gears
High rpm’s, reversal of load direction, low vibration excitation, high contact ratios, increased risk of scuffing, deformed housings ... the design, optimization and service life calculation of gears for e-drives is a world of its own. The presentation shows how individual requirements can be covered by the choice and variation of gear geometry. Parameters such as material selection or heat treatment are deliberately ignored to concentrate on gear geometry optimization, which is readily accessible to the designer. Three dimensions are addressed: macro geometry, modifications and manufacturing deviations. This presentation is rounded off with the peculiarities of strength calculation in case of frequent changes in torque direction with torque-time series measured from test rigs.

Manufacturing of e-Drive Gears
E-drive transmissions are different than conventional transmissions, creating new challenges for manufacturing processes. This presentation showcases processes for soft and hard finishing of typical gears in e-drive transmissions. Featured processes include hobbing, chamfer cutting, shaping, Power Skiving, gear honing and threaded wheel grinding, including the appropriate tool technology.

Gear Noise Evaluation by Analytical Inspection and NVH Roll Testing
Gear noise has become a challenge in automotive e-drives and other applications with extremely demanding gear characteristics. Understanding gear noise in general is the foundation for tracing critical noise sources as a base for counter measures. This presentation provides a basic understanding of the origin of gear noise, as well as the possibilities of analytical measurement and NVH roll testing of cylindrical gears with special software and hardware technologies.
