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.

Klingelnberg has developed a new precision measuring center. The P 152 is the latest addition to the family of Klingelnberg precision measuring centers. It is capable of measuring components with a maximum outside diameter of 1,520 mm and workpiece weights up to 8,000 kg with the usual precision. 

Aircraft engines can be made more efficient by integrating planetary gears. In such an application, the planetary gears experience very high load cycles under fully reversed bending loads. Pulsator test rigs, which nowadays offer the possibility to perform UHCF investigations, can only be used for purely pulsating loading of gears. Therefore, for the investigation of the UHCF tooth root load carrying capacity under fully reversed bending load, a back-to-back test rig is required. Back-to-back test rigs usually have speeds of n = 3,000 rpm, which makes investigations in the UHCF range take a very long time. Therefore, a high-speed back-to-back test rig was developed.

Nidec Machine Tool (Wixom, Mich.), responding to the needs of the industry, is debuting the new GE15HS gear hobbing machine at IMTS 2022 in Booth #237036. Emphasizing high speed, precision and efficiency, the new machine produces gears for electric and hybrid cars, as well as for robotic and automation applications.

At IMTS 2022, Norton ׀ Saint-Gobain Abrasives (Booth #237042, North Hall) will offer a portfolio of gear grinding products specifically designed by category to provide higher profile accuracy, supreme form holding and burn-free grinding in worm, profile, and bevel applications. Highlighting the range is an innovative dual-worm wheel design that enables two operations in one grinding wheel, substantially saving time and cost. 

Klingelnberg examines gear noise behavior and the evolution of the electric powertrain. 

LK Metrology and Wenzel Technologies have entered into a strategic partnership with immediate effect. In addition to a joint technological cooperation, Wenzel Technologies will sell LK's innovative, high-performance coordinate measuring machines (CMMs) and other metrological products in southern Germany.

The objective of this paper is to improve the methodology for determining the tooth flank temperature. Two methods are proposed for assessing scuffing risk when applying AGMA 925 for high-speed gears. Both methods provide similar results.

Tool-X is a nanofluid that changes the characteristics of existing metalworking fluids by ‘manipulating’ speeds, feeds and metal removal rates using nanotechnology. The science behind Tool-X can potentially change metal cutting dynamics, improve surface finishes and extend tool life. The backstory of this technology is just as fascinating as its production results.

Within the last decade, hard finishing technologies become highly relevant. Increasing the power density of a gearbox requires precisely machined gears without heat distortions. Especially in noise-sensitive applications, both honing and grinding are often applied.
