Rack and pinion animation
A pinion is a round gear used in several applications:
- usually the smaller gear in a gear drive train, although in the case of John Blenkinsop's Salamanca, the pinion was rather large.[1] In many cases, such as remote controlled toys, the pinion is also the drive gear.
- the smaller gear that drives in a 90-degree angle towards a crown gear in a differential drive.
- the small front sprocket on a chain driven motorcycle.
- the round gear that engages and drives a rack in a rack and pinion mechanism and against a rack in a rack railway.
- in the case of radio-controlled cars with an engine (i.e. nitro) this pinion gear can be referred to as a clutch bell when it is paired with a centrifugal clutch.[2]
