Benefits of Spiral Torsion Springs
A spiral torsion spring offers numerous benefits, but its design is the key factor that makes it so effective across many applications. These springs are relatively small and flat, making them the ultimate space savers.
While manufacturing the spring, a concentric spiral forms. This spiral allows the spiral torsion to be compact and creates a unique helical design. Due to the design, the spring can rotate in both directions with a “return to center.” This small component envelope makes the spiral torsion spring a great fit for many high-intensity and space-conscious designs.
Versatility in Application
The variety of small and large spiral torsion spring applications across industries indicates their versatility. Common markets and applications for these springs include the following:
- Aerospace and Defense
- Flight control systems, satellite systems, landing gear, jet stairways, armored hatch covers, and primary or cargo doors
- Automotive
- Braking systems, stabilizer bars, suspension control arms, clutch mechanisms, and trailer tarp systems
- Consumer Goods
- Watches, mechanical clocks, children’s toys, and sporting goods
- Medical Devices
- Clamps, forceps, retractors, diagnostic or surgical tools, implants, and dental X-ray head units
- Industrial Equipment
- Automated assembly lines, robots and robotic joints, and packaging systems
- Specialty Applications
- Damper and valve actuation, motor brush assemblies, and electric motors
Within these components, equipment, and systems, spiral torsion springs effectively store and release the rotational energy necessary to generate motion, resulting in controlled torque, reduced stress and torque loss, consistent and reliable performance, and enhanced durability and longevity of a product.
Spiral torsion springs are useful for motion applications in which short rotations under 360° are necessary, or those requiring torque that need short rotation, most typically one rotation or less.
Spiral Torsion Spring Benefits
The linear relationship between deflection and the resulting torque in spiral torsion springs allows for precise control. These springs store and release energy by applying rotational force, making them highly effective and versatile. Their unique design offers several benefits, making them suitable for a wide range of applications.
These applications include:
- Compact and efficient energy storage
- Compared to traditional compression springs, spiral torsion springs are capable of storing more energy while fitting into smaller, more compact spaces. These compact springs provide an ideal fit in applications with space restrictions.
- High torque with minimal rotation
- Delivering impressive torque through rotations that are typically less than 360°, spiral torsion springs are well suited to tasks that necessitate high rotational force but minimal motion.
- Durability and longevity
- Spiral torsion springs hold up well against repetitive twisting and untwisting movements, helping avoid premature fatigue failure in your equipment for long-lasting performance. This reliable durability also lends them the advantage of being a cost-effective choice for cross-industry applications.
- Versatility and customizability
- The versatility of spiral torsion springs allows them to be tailored to meet specific requirements. They are highly customizable to fit the needs of a range of projects. You can select the material composition, outer and inner diameters, and amount of coils in the design to best suit your unique needs. Last, they offer flexibility in mounting options using:
- L hubs or collet
- Hooks and pins or slot-mounts
- Tabs and keyways
- Hinged or clamped for free or restricted movement
