What's In a Name

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.

Experimental Study on the Pitting Detection Capabilities for Spur Gears Using Acoustic Emission and Vibration Analysis Methods

Relationship between Misalignment and Transmission Error in Cross- Axes Helical Gear Assemblies

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)?
