It's time to catch up on the episodes of Revolutions that you might have missed.

Noise issues from gear and motor excitation whine are commonly faced by many within the EV and HEV industry. In this paper the authors present an advanced CAE methodology for troubleshooting and optimizing such NVH phenomenon.

Question: I am a gear engineer for a motor manufacturer in China. I am writing about noise generated from cross-helical gear assembly error. I want to learn the relationship between the misalignment (center distance change and cross-angle shift) and transmission error. It is better under the loading and theory conditions. What is the trend of cross-helical gear development (use ZI worm and involute helical gear, point contact)?

The latest advances in gear manufacturing automation all seem to revolve around a common theme: automated loading.

New turnkey, "off-the-shelf" Gleason 2700AR system automates larger-gear load/unload to speed throughput, optimize process flow - and take the weight off the operator.

Workholding Systems Continue to Focus on Speed and Efficiency to Improve Machining Operations

As most of you know by now, the trade show formerly known as Gear Expo is now the Motion + Power Technology Expo. If you're a gear-industry veteran, you might be confused by this change. If you've been coming to the show for years - or exhibiting at it - you might even feel a little betrayed. But I'm here to tell you it's going to be alright.

Like many fathers, I once had hopes of one of my children follow in my footsteps. When my son was four years old he even publicly declared his goal...
