Constant Force Spring Benefits
Constant Force Spring Benefits
- Small Space Requirements
Their design allows tight coiling, making them an excellent choice for devices with limited space.
- Smooth Range of Motion
The nearly flat force curve ensures a consistent force throughout their extension. This provides a smooth and reliable range of motion, essential for applications requiring precision and stability.
- No Inertia to Overcome
Unlike traditional springs, they do not have significant inertia to overcome at the beginning of their movement. This makes them ideal for applications that require immediate and responsive action.
- Easy Mounting to Existing Hardware
Versatile and easily integrated into existing hardware setups. This flexibility simplifies the design process and can reduce manufacturing time and costs.
- Counterbalance Effect
Useful in applications where a constant load needs to be counterbalanced, such as in retractable mechanisms or adjustable systems.
Versatile Applications
Constant force spring benefits make them suitable for a wide range of applications, including:
- Surgical Devices: Enhancing precision and control in medical instruments.
- Aircraft Doors: Used in a “gang” arrangement, i.e. side by side in a multi-spring assembly. This allows for hundreds of pounds of counterbalance force to be available to assist in opening & closing the main entry door/stairs, or cargo doors.
- Windows: Providing a counterbalance for smooth opening and closing operations.window curtain spring
- Fire Dampers: Supply steady and consistent force, and well-suited for the certain opening and closing actions needed in fire dampers. Fire Damper Spring
- Gym Equipment: Replace the need for weights in gym equipment using the force of the springs to act the weight. 50 pounds of force in a lightweight spring is then 50 pounds of weight saved, making the equipment lightweight and more compact.
- Electric Motors: The springs allow the motor to run efficiently without arcing or other gaps in power. As the commutator turns, the brushes become worn over time due to friction. The springs ensure proper contact force against the commutator as they wear.Motor Brush Spring
