Understanding the factors that influence worm gear reducers’ performance will lead to more cost-effective and efficient ...

Author and professor Steve Radzevich discusses the third revision to Dudley’s Handbook of Practical Gear Design and Manufacture, and the essentials gear designers should know. This file type includes ...

Whether you have a mechanical limited-slip differential (LSD) in your car you stand to benefit from knowing how one works. Not so you can know how to fix it or anything—just because they’re a ...

Researchers create light-driven gears on microchips, paving way for micromotors in medicine and lab-on-a-chip systems.

Many mechanical devices have been inspired by examples in nature, but it’s not often that nature replicates something only known to be made by human beings. Meet Issus coeleoptratus, more commonly ...

Gears and wheels are not very common in nature. Recently however, biologist have discovered a precision gearing mechanism that is built and used by an insect known as a planthopper. The bug employs ...

The small hopping insect Issus coleoptratus uses toothed gears (magnified above with an electron microscope) to precisely synchronize the kicks of its hind legs as it jumps forward. All images ...
