screw-wheel
Definition
Noun: - A gear with screw-like threads: A "screw-wheel" is a mechanical component, typically a wheel or gear, that has helical threads or teeth designed to mesh with a worm or screw, often used in machinery to transmit motion or power. It is also known as a worm gear or worm wheel.
Usage Examples
- (A mechanical part with threads that interacts with a screw.)
- (A wheel with helical threads used in precision machinery.)
Advanced Usage
"Screw-wheel drive": A system where a screw-wheel is used as the driven component in a worm gear assembly.
- The screw-wheel drive ensures smooth and quiet operation in heavy machinery. (The worm gear system reduces noise and vibration.)
"Screw-wheel ratio": The gear ratio determined by the number of threads on the screw-wheel relative to the worm.
- A high screw-wheel ratio provides greater torque but slower speed. (The mechanical advantage is increased with more threads.)
Variants and Related Words
Worm wheel (n): a synonym for screw-wheel, especially in engineering contexts.
- The worm wheel is essential for converting rotational motion into linear motion. (A toothed wheel that meshes with a worm screw.)
Screw gear (n): a gear with helical threads, similar to a screw-wheel.
- The screw gear is used in steering systems for precise control. (A gear with a helical design.)
Synonyms
- Worm gear: a gear that meshes with a worm (a screw-like component).
- Helical gear: a gear with teeth cut at an angle to the axis, though not always identical to a screw-wheel.
Related Idioms
- To turn the screw-wheel: to adjust or control a mechanism, often metaphorically.
- He had to turn the screw-wheel to increase the machine's output. (Literally rotating the wheel to change settings.)
