speed-reducer
Definition
Noun: - A device that reduces rotational speed: In mechanical engineering, a "speed-reducer" is a mechanism (often a gear system) that decreases the speed of a rotating input shaft relative to its output, typically to increase torque.
Usage Examples
- (A device that slows down the rotation of the motor's shaft.)
- (A component that lowers the rotational speed to a safe or useful level.)
Advanced Usage
"to incorporate a speed-reducer": to include a speed-reducing mechanism in a machine.
- The engineers decided to incorporate a speed-reducer into the design of the electric winch. (They added a gearbox to lower the speed and increase pulling force.)
"a two-stage speed-reducer": a speed-reducer that uses two sets of gears to achieve a greater reduction in speed.
- The heavy-duty crane uses a two-stage speed-reducer for precise lifting control. (A gearbox with two gear pairs for significant speed reduction.)
Variants and Related Words
Speed-reducing (adj): describing something that reduces speed.
- The speed-reducing gearbox is essential for the machine's operation. (The gearbox that lowers speed.)
Reducer (n): a shortened form of "speed-reducer", often used in technical contexts.
- Check the oil level in the reducer before starting the engine. (Check the lubricant in the speed-reducing gearbox.)
Synonyms
- Gearbox: a mechanical device that uses gears to change speed or torque.
- Reduction gear: a set of gears designed to reduce rotational speed.
Phrasal Verbs
- Slow down: to cause something to move or operate at a lower speed.
- The speed-reducer helps to slow down the motor's output. (It reduces the rotation rate.)
Related Idioms
- Put the brakes on: to reduce or stop progress or speed.
- The new safety regulations put the brakes on the project's rapid pace. (They slowed down the project's speed, analogous to a speed-reducer's function.)
