Pinion and annular gear
A pinion is a round gear—usually to the smaller of two meshed gears—used in several applications, including drivetrain and rack and pinion systems.
Applications
Drivetrain
Drivetrains usually feature a gear known as the pinion, which may vary in different systems, including
- the typically smaller gear in a gear drive train (although in the first commercially successful steam locomotive—the 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 clutch bell gear when paired with a centrifugal clutch, in radio-controlled cars with an engine (e.g., nitro).[2]
Rack and pinion

In rack and pinion system, the pinion is the round gear that engages and moves along the linear rack.
