Acanted coil spring, also known as a slant coil spring or simply a canted spring, is a type of helical spring with a unique design. Unlike traditional coil springs, they are wound at an angle or with a slant to the axis of the coil. This design imparts specific properties and advantages to canted coil springs, making them suitable for certain applications.
Slanted Windings: Canted coil springs have their coil windings oriented at an angle to the central axis. This slanted or canted configuration allows for a unique spring behavior.
High Load Capacity: They are known for their high load-carrying capacity relative to their size. This makes them suitable for applications where space is limited, but substantial force or pressure needs to be applied.
Constant Force: One of the primary advantages of them is their ability to provide a relatively constant force over a range of deflections. This feature is valuable in applications like cable management systems and retractable devices.
Linear Load/Deflection Characteristics: They often exhibit linear load/deflection characteristics, meaning the force they exert is directly proportional to the amount they are compressed or extended. This predictability is useful in various engineering applications.
Applications:
Cable Management: These springs are frequently used in cable and wire management systems, such as retractable cords for power tools or appliances.
Medical Devices: They can be found in medical devices like retractable catheters.
Automotive: In the automotive industry, canted coil springs are used in applications like seatbelt retractors.
Aerospace: Canted coil springs are used in aerospace applications, including mechanisms for deploying equipment.
Material Selection: They can be made from various materials, including stainless steel and specialty alloys, depending on the application’s requirements.
Canted coil springs are valued for their unique combination of characteristics, including their compact size, high load capacity, constant force behavior, and linearity. These properties make them well-suited for applications where these specific features are essential.
