Resource efficiency and environmental protection are becoming increasingly important in modern transmission development processes, especially minimizing the CO2 footprint. These factors are critical for complying with regulatory limits and remaining competitive in a challenging market.

Gearboxes used in electric vehicles are not only designed for high speeds and high torques – they are also very compact. This is not only true for the automotive sector, but also – and above all – for innovative types of applications such as e-bikes. These small but high-power and electrically driven gearboxes inspire design engineers to come up with more creative solutions. In many cases, they comprise small components with interfering contours, which pose new challenges for production. When it comes to the hard finishing of the gear teeth, the process-related potential goes hand in hand with high production costs. The most economical option is probably generating grinding. However, not all generating grinding machines are suitable for the production of the compact components. This article outlines the relevant demands and demonstrates possible solutions.
