Sprocket: meaning, definitions and examples

This term is often used in mechanical and bicycle-related contexts to refer to a wheel with teeth or cogs that fits into the links of a chain.

• The chain fell off the sprocket on my bike, and I had to fix it.
• The sprocket needs to be replaced as it is too worn out.

This is a general term used to describe circular mechanical devices with teeth that mesh with another gear to transmit torque. It is often used in mechanical engineering and automotive contexts.

• The gearwheel in the clock mechanism is worn out and needs to be replaced.
• Engineers are working to improve the efficiency of gearwheels in modern engines.

This term can refer both to the individual teeth on a gearwheel and to the gearwheel itself. It is also used metaphorically to describe a small part of a larger machine or system, often implying someone or something of minor importance.

• Each cog in the machine must be precisely aligned for the mechanism to work smoothly.
• He felt like just another cog in the corporate machine.

This is a broad term that can describe any circular object that rotates on an axle. It can be used in a variety of contexts, including vehicles, machinery, and even metaphorically to describe cycles or processes.

• The wheels of the car need to be aligned properly for safe driving.
• She decided to reinvent the wheel when she created a new process for data management.
• The potter spun the wheel to shape the clay.

Used mainly in machinery and bicycles, this term refers to a wheel with teeth that meshes with a chain or track to transmit motion.

• The bike’s chain slipped off the sprocket.
• Engineers need to ensure the sprocket is aligned correctly for optimal performance.

Common in various mechanical contexts, gears are wheels with teeth that interlock with each other to transfer or change the direction of motion. It is also metaphorically used to refer to equipment or apparatus.

• The clock’s gears need regular maintenance to keep it running smoothly.
• She packed all her camping gear for the weekend trip.

A circular object that rotates and is usually part of a larger mechanism or vehicle. More generally, 'wheel' can refer to any object or concept involving circular motion or travel.

• The car needs new wheels before the long trip.
• The wheel was one of the greatest inventions in human history.

A simple machine consisting of a wheel over which a rope or chain is pulled, often used to lift heavy objects by redirecting force.

• The workers used a pulley to lift the heavy crate onto the truck.
• A pulley system can significantly reduce the effort needed to hoist large loads.
