Spiral Springs/渦形彈簧

Power Spring

A Power Spring, also known as a Clock Spring or Spiral Spring, is an energy-storage elastic component made by winding a strip of spring steel into a spiral coil. It converts externally applied mechanical energy into stored elastic energy and releases it when needed, providing stable rotational torque output.

Power springs feature high energy density, stable torque output, compact size, and long service life. They are widely used in mechanical devices that require energy storage and automatic return functions.

Constant Force Spring

A Constant Force Spring, also known as a Constant Force Coil Spring, is an elastic component manufactured from specially heat-treated spring steel strip wound into a coil. Its primary characteristic is its ability to provide an almost constant pulling force throughout the extension and retraction stroke, unlike conventional extension springs whose force increases significantly as they are stretched.

A constant force spring stores energy through the bending stress of the spring strip. As the spring is extended or retracted, it continuously delivers a stable force output. Therefore, it is widely used in applications requiring uniform pulling force, weight balancing, and automatic return functions.

Spiral Spring

A Spiral Spring, also known as a Coil Spring or Spiral Coil Spring, is an elastic component made by winding spring steel strip or wire into a spiral shape. Its primary function is to store and release energy through elastic deformation while providing rotational torque, return force, or positioning functions.

Spiral springs feature high energy storage efficiency, stable torque output, compact construction, and long service life. They are widely used in mechanical devices, automatic return mechanisms, and precision equipment.
