Definition
- Noun:
- A type of gear with straight teeth cut parallel to the gear's axis: A "spur gear" is a cylindrical gear with teeth that are straight and aligned parallel to the axis of rotation. These teeth mesh with the teeth of another spur gear on a parallel shaft.
Usage
- Noun:
- The simplest and most common type of gear is the spur gear.
- For this simple transmission, we will use two spur gears.
- Spur gears are used to transfer motion between parallel shafts.
Examples
- Noun:
- The clock mechanism uses a series of small spur gears.
- A common example of a spur gear is found in a manual can opener.
- The design requires a spur gear with 24 teeth.
Advanced Usage
- Engineering Context: In mechanical engineering, "spur gear" specifies the gear type, often in contrast to helical, bevel, or worm gears. Their simplicity makes them cost-effective for many applications.
- The noise level is higher for spur gears compared to helical gears.
