Product Description


Industrial Extension Constant Force Flat Spiral Torsion Spring


Constant Force Spring

A spring is a device used to start a machine by winding up a sheet of steel and using its elasticity to gradually loosen. Mechanical clocks, watches, and clockwork toys are all clockwork.
The energy of the spring will gradually weaken with the operation of the movement, according to the principle of lever torque: when the spring is full, its torque is the largest (the longest torque lever), so the front end of the spring needs to output a smaller force. After running for a period of time, the spring of the tight coil on the spring shaft will slowly loosen, and its energy will decrease. When the energy is about to run out, the torque at the end of the spring is the smallest (torque lever is the shortest), at this time the output force also becomes smaller, so the transmission force needs to increase to maintain the movement.

1. What is a flat spiral spring?
Flat spiral springs are also known as spiral torsion, clock springs or brush springs. They are characterized by the requirement that the coil contact is minimized during operation. Springs are designed to customer requirements and are used in the automotive, medical, industrial and office equipment markets.


2. What is a flat spring called?
Flat springs are sometimes called leaf springs and are often custom-formed from flat spring steel for specific purposes. Many trucks and some automobiles use leaf springs for their suspensions.


3. How do flat spiral springs work?
Energy-saving and space-saving to generate force in the direction of rotation. A flat spiral spring is made by winding a band-shaped material so that its central line forms a spiral on a plane, and acts as a spring by applying an external force to one end of the spring.


4. What are flat coil springs used for?
Flat coil springs are also used in automotive applications. They are flat springs used with a counterweight to control the action of valves, such as in a vehicle exhaust system. A flat coil spring is wound into a specific configuration to absorb shock or provide tension.


5. What are the applications of spiral spring?
Spiral spring is widely used in mechanisms, such as mechanical watch movements and clocks where the spiral spring is used for timekeeping.
