spiral spring
Noun: A spiral spring is a mechanical device, typically made of elastic material (such as steel), that is wound in a continuous, coiled, or helical shape. It stores mechanical energy when twisted or compressed and releases it when the force is removed, returning to its original shape. This type of spring is characterized by its spiral form.
The term spiral spring is used to describe a specific component in mechanics and engineering. It functions by twisting around its axis. - It is commonly found in clocks, watches, toys, and various mechanical assemblies to provide torque or tension. - The defining feature is its spiral or helical winding, distinguishing it from other spring types like leaf springs or compression springs.
- The old pocket watch stopped because its spiral spring was broken.
- The toy car uses a spiral spring to power its movement when wound up.
- Engineers selected a high-quality spiral spring for the retraction mechanism.
- As a component in energy storage: In horology (clockmaking), the spiral spring (often called a mainspring) is a crucial energy source.
- In precision instruments: Its ability to deliver consistent force makes it suitable for sensitive measuring devices.
- Mainspring (n): A specific type of powerful spiral spring used to drive the mechanism of a watch, clock, or other device.
- Helical spring (n): A broader term for any spring coiled into a helix; a spiral spring is a type of helical spring often wound in a flat spiral plane.
- Clockwork spring (n): Another term emphasizing its use in clockwork mechanisms.
- Coil spring (though this can sometimes refer to cylindrical helical compression springs)
- Flat spiral spring
- Spring mechanism: A general term for any device using a spring.
- Power spring: A term highlighting its function as an energy source.
The term spiral spring specifically refers to the object's physical form and function. It is a compound noun where "spiral" describes the shape of the "spring."
