Constant Force Spiral Spring

The Constant Force Spiral Spring - which is commonly referred to as "the mainspring" in the watchmaking industry - is a crucial component of the mechanical watch movement. It works in conjunction with the balance wheel to form an accurate oscillator.

Its characteristic of being able to wind and unwind in a stable and regular rhythm enables mechanical watches to provide accurate timekeeping. The spiral spring requires extremely high precision and stability in response to temperature changes. Even the slightest difference between them can cause the watch to lose accuracy or even result in significant deviations.

This is why it is one of the most meticulously designed components in the entire field of precision machinery.

Product Details

In the automotive industry, the Constant Force Spiral Spring is a crucial safety component - it is located inside the seat belt retractor. Its main function is to maintain a certain tension for the seat belt webbing.

The carefully adjusted belt tension allows you to easily roll it up and secure it neatly when not in use, saying goodbye to the trouble of it being scattered everywhere and keeping it tidy at all times. This spiral spring needs to have stable torque and be able to withstand multiple uses.

It must reliably work for thousands of cycles throughout the entire lifespan of the vehicle, which directly contributes to improving the convenience and safety of drivers or passengers.

FAQ

Q:What are the most common applications for a spiral Spring, and how is its energy storage capacity calculated?

A:A Constant Force Spiral Spring is ideal for applications requiring constant torque and numerous rotations, like cable reels, retractable cords, and certain mechanical actuators. Its energy storage capacity is a function of the material's modulus of elasticity, the strip's width and thickness, and the total number of rotations. We precisely calculate this for each custom spring to ensure it delivers the required torque and rotational cycles for your specific mechanism's needs.
