spur wheel
Definition
Noun: A spur wheel is a type of gear wheel with straight teeth that are cut parallel to the wheel's axis. It is designed to mesh with another gear in the same plane, transmitting motion and power between parallel shafts.
Usage
The term spur wheel is used specifically in mechanical and engineering contexts to describe a fundamental component in gear systems. It is the most common and simplest type of gear.
Examples
- The old mill's machinery was driven by a large wooden spur wheel.
- For this simple parallel shaft arrangement, a spur wheel is the most efficient gear choice.
- The engineer examined the worn teeth on the spur wheel to diagnose the source of the noise.
Advanced Usage
- Spur wheel design involves calculations for pitch diameter, number of teeth, and module to ensure proper meshing and power transmission.
- In horology (clockmaking), precision spur wheels are essential components of the gear train.
Variants and Related Words
- Spur gear: This is a more common and synonymous term for spur wheel. The two terms are often used interchangeably, though "spur gear" is more prevalent in modern engineering.
- Pinion: A small gear that meshes with a larger one; a spur wheel can be a pinion if it is the smaller of a meshing pair.
- Gear wheel: A general term for any toothed wheel designed to mesh with another; a spur wheel is a specific type of gear wheel.
Synonyms
- Spur gear
- Straight-toothed gear
Antonyms
- Bevel gear: A gear designed to mesh at an angle (not in the same plane), typically for connecting intersecting shafts.
- Helical gear: A gear with teeth cut at an angle to the axis, which meshes more smoothly but can introduce axial thrust.
Related Phrases
- To mesh: The action of gear teeth engaging with one another. A spur wheel is designed with another gear in the same plane.
- Parallel shafts: The typical configuration for a system using spur wheels.
Noun
-
gear wheels that mesh in the same plane
