Definition

Noun: A geared wheel is a wheel with teeth (called cogs or gear teeth) cut into its rim. It is designed to mesh with another toothed component, such as another geared wheel or a chain, to transmit rotational motion and force. Its primary function is to change the speed, torque, or direction of motion within a mechanical system.

Usage

A geared wheel is a fundamental component in machinery. It must engage with another toothed mechanism to function. * The clock's mechanism relies on a series of geared wheels to move the hands accurately. * To increase the torque, a small geared wheel drives a larger one.

Examples

• The bicycle's pedal motion is transferred to the rear wheel via a chain and a geared wheel.
• In a car's transmission, a geared wheel from the engine engages with others to change the vehicle's speed.
• The engineer replaced the worn geared wheel to restore the machine's smooth operation.

Advanced Usage

• Precision Engineering: In high-performance applications, a geared wheel must be manufactured to extremely tight tolerances to minimize noise and wear.
• As a System Component: The term often implies the wheel's role within a larger assembly, such as a gear train or transmission, where multiple geared wheels interact.

Variants and Related Words

• Gear (n.): A more general term that can refer to a single geared wheel or a system of such wheels. (e.g., )
• Cogwheel (n.): A near-synonym for geared wheel, though sometimes implying a simpler or smaller wheel.
• Pinion (n.): A specific type of geared wheel, typically the smaller of a pair of meshing gears.
• Sprocket (n.): A geared wheel designed to engage with a chain or track, rather than another gear.

Synonyms

• Cogwheel
• Gear

  • The new gear must mesh perfectly with the existing geared wheel.
• Gear train: A series of geared wheels that transmit motion from one part of a machine to another.

Noun

1. a toothed wheel that engages another toothed mechanism in order to change the speed or direction of transmitted motion
