Overall developments and widespread public awareness of man-made climate change are transforming the way people think. The awareness has inspired a shift towards a more ecologically sustainable way of life. Driven by policymaking and technological innovation, ambitious efforts are underway to reduce greenhouse gas emissions to curb the rise in average temperatures. A key focus of these efforts is the mobility sector. 

A deep dive into the world of gear dynamics and gear noise has led many a mechanical engineer to Columbus, OH in search of the methods by which gear noise is measured and predicted as well as the techniques employed in gear noise and vibration reduction. Over the past 40+ years, about 2,550 engineers and technicians from 385+ companies have attended the Gear Dynamics and Gear Noise Short Course at The Ohio State University.

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. 

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

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.

With its brand-new 300GMS nano Gear Metrology System, Gleason presents a world- first at Control Show 2022, May 03-06, Stuttgart, Germany. The capability of measuring gears at sub-micron level, executing advanced waviness analysis and evaluating gear noise using the most advanced analytical tools, make the 300GMS nano ideally suited to support automotive e-drive production with minimum noise requirements.
