pinion etymology

Etymology:

  • Middle English: pinyoun, from Old French: pignon, from Latin: pinio, meaning "pine nut"

Meaning:

  • A small, toothed wheel that meshes with a larger, often helically cut gear

Origin:

The origin of the word "pinion" can be traced back to the Latin term "pinio," which referred to a pine nut. This is because the teeth of a pinion gear resemble the shape of pine nuts.

In medieval times, pinions were used in windmills and watermills to transmit power from the main shaft to the grinding stones. They were also used in clocks and other mechanical devices.

Over time, the use of pinion gears expanded to other applications, such as automotive transmissions, steering systems, and industrial machinery. Today, pinion gears are an essential component of many different types of machines and devices.
