Introduction

Constant force springs are crucial components in various mechanical applications, including clocks. Understanding their function and benefits helps in appreciating their significance in maintaining accuracy in timekeeping devices.

What is a Constant Force Spring?

A constant force spring is a type of spring that exerts a consistent force over its range of motion. Typically constructed of pre-stressed strip material, these springs uncoil as they function, offering a linear deployment of force unlike conventional springs which exert variable forces.

Application in Clocks

In horological devices, precision and consistency are imperative. Constant force springs ensure a uniform release of energy, which is essential for maintaining the accuracy of a clock’s mechanism. These springs mitigate issues with varying torque outputs found in traditional coil springs.

Numerical Analysis

The mathematical model of a constant force spring can be expressed through Hooke’s Law as F = kx, where the force (F) remains constant regardless of the extension (x) of the spring. Unlike other springs, in a constant force spring, k (spring constant) practically approaches zero, keeping F unchanged. Experimental data indicate that a standard constant force spring can maintain a force accuracy of ±0.5% over its lifespan, covering tens of thousands of cycles.
