What's In a Name (Publishers Page)
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.

Relationship between Misalignment and Transmission Error in Cross- Axes Helical Gear Assemblies (Ask the Expert)
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)?
