The trend towards hard fine finishing of gears for automotive transmissions is accelerating. In recent years, the focus has been on increasing the efficiency of gears in order to make optimum use of the narrow gear ratio range, gear by gear, and to reduce fuel consumption. Surface finish, in particular, is under increased scrutiny since it plays such a decisive role in achieving the noise and efficiency requirements of gear units for today’s EV applications.
Nagel and Gehring recently shared innovative technologies during AMB 2022 including new standards in efficient honing, maximum flexibility in the superfinishing of flat, concave, and spherical surfaces, and efficient internal and external honing of workpieces.
