Manufacturers must produce lighter and more compact EV transmissions from tough materials such as low-alloy steels—and those that rely on traditional manufacturing processes risk falling behind. Mats Wennmo, Global Automotive Transmission Manager at the metal cutting specialist Sandvik Coromant, explains why gear skiving is crucial for competitive manufacturing.
 

Electric vehicles or EVs are increasingly popular options for people who want to save money on gas and decrease their reliance on fossil fuels.

System-supplier Klingelnberg will be back at AMB (Booth C41, Hall 5), where it will be highlighting solutions for smooth-running gearboxes. The exhibit will feature the Höfler Cylindrical Gear Grinding Machine Speed Viper, the Klingelnberg Precision Measuring Center P 40 and the newly developed Höfler Cylindrical Gear Roll Testing Machine R 300. 

When it comes to an early identification of noise problems in the drivetrain one has to take data analytics and its integration in the manufacturing process into account. The big vision here, in particular, is preventive quality. By evaluating sensor data of the machining process, it promises to predict whether a gear is ok or not ok. 

EMAG will highlight productive, and at the same time, flexible manufacturing solutions for electromobility at IMTS. Among other things, the focus is on the vertical pick-up lathes of the VL series, which EMAG now delivers IoT-Ready.

The ANCA Integrated Manufacturing System (AIMS) optimizes cutting tool production through streamlined manufacturing, automation, and connectivity. With ANCA and AIMS, customers can achieve continuous, unattended production that dramatically reduces non-productive machine time, with smart automation that connects sequential tool production processes and offers connectivity across the whole factory. 

Kapp Niles will highlight a variety of machine tool technologies at IMTS 2022 for areas like mobility, automation, energy, and more.

In the course of the mobility transition, electric and hybrid drives will gradually replace the traditional combustion engine. The battery is a key element in electrification: More and more manufacturers are starting their own production of battery systems and are looking for suitable solutions to do so. Liebherr has looked into the processes extensively and offers system-capable, modular concepts for the automated assembly of battery packs.

At IMTS 2022 in Booth #135621, Marposs will be demonstrating OptoCloud EDU (Electric Drive Unit), its latest generation of 3D precision inspection solutions designed for the electrical vehicle industry. Using multiple laser heads in tandem with contact sensors for measurement and vision inspection, OptoCloud EDU reconstructs the 3D model of complex and articulated workpieces in less than a minute to ensure accuracy of the produced component.  For example, it can validate 240 electrical contacts of a motor stator in only 30 seconds, which is 100 times faster than a traditional contact system.

The fascination of the automotive differential has led to the idea to build a second differential unit around a first center unit. Both units have the same axes around which they rotate with different speeds. The potential of double differentials as ultrahigh reduction speed reducers is significant. Only the tooth-count of the gears in the outer differential unit must be changed in order to achieve ratios between 5 and 80 without a noticeable change of the transmission size.
