Pinion

Pinion

A pinion is usually the smallest gear in a gear drive train. In many cases, such as remote controlled toys, the pinion is also the drive gear. In the case of John Blenkinsop's "The Salamanca" the "pinion" was rather large.

The term is also commonly used to describe the smaller gear that drives in a 90-degree angle towards a crown gear in a differential drive.

ee also

* Rack railway
* Rack and pinion
