Canted coil springs, often referred to simply as canted springs, are a type of helical spring with a unique design characterized by their canted or slanted coils. The term “canted” means that the coils of the spring are not perpendicular to the central axis but are instead at an angle to it. This design imparts some distinct properties and advantages to canted coil springs, making them suitable for specific applications.
1. Constant Force: Canted coil springs are known for their ability to provide a relatively constant or uniform force throughout their range of deflection. This feature is highly valuable in applications where a consistent force is required, such as retractable cords and cable management systems.
2. Linear Load-Deflection Characteristics: Canted coil springs often exhibit linear load-deflection behavior, meaning that the force they exert is directly proportional to the amount they are compressed or extended. This predictability is advantageous in engineering and design applications.
3. High Load-Carrying Capacity: Despite their relatively compact size, they can handle high loads. This makes them suitable for applications where space constraints exist, but substantial force needs to be applied.
4. Compact Design: Their unique slanted coil design allows them to fit into tight spaces and operate efficiently.
5. Applications: Canted coil springs find use in various applications, including but not limited to:
6. Material Variety: These springs can be manufactured from a range of materials, including stainless steel and specialty alloys, depending on the specific requirements of the application.
In summary, canted coil springs offer a unique combination of features, including constant force, linear load-deflection behavior, and high load-carrying capacity, which make them ideal for applications where these properties are critical. Their compact design and ability to provide consistent force over a range of deflections make them valuable components in various engineering and design contexts.
