For over 10 years, the mechanical engineering company Kapp Niles has been working intensively on the topic of gears in e-mobility and has established itself as a pioneer in this rapidly growing industry. With a focus on innovation and quality, Kapp Niles offers customized solutions for the production of gearboxes and gears in electric vehicles.
Nidec Machine Tool Corporation (“Nidec Machine Tool” or the “Company”), a group company of Nidec Corporation, today announced that it has developed the a high-accuracy polishing (grinding) method to machine internal gears for mass production that are used for automobiles’ drive units and transmissions and robots’ joints. While there are already high-accuracy polish-machining methods for external gears for mass production, no such methods have been available for internal gears. After conducting research focused on this point, the Company has achieved positive results in securing the level of accuracy and production that conventional grinding, honing, or skiving methods could not.
This article introduces the process of polish grinding of gears. Improved surface quality increases the overall efficiency of gearboxes, resulting in reduced friction and torque loss, higher power density, and noise-optimized gears (lower NVH); all these factors are highly relevant, especially for electric drives. When Reishauer developed polish grinding in 2012, the process aimed to improve the efficiency of ICE engine transmissions, and the set goals were easy to achieve. Today, in 2023, the situation is dramatically different. While an ICE engine operates at around 3,000 rpm and supplies acoustic masking of the gear noise, EV drivetrains feature up to 20,000 rpm and offer no such masking.
