Compression springs come in various types and configurations, each designed to meet specific application requirements. Here are some common types of compression springs based on their configurations:
Constant Pitch Springs: These springs have a consistent pitch (spacing between coils) throughout their length, providing uniform force and deflection characteristics.
Conical Springs: Conical compression springs have a tapered shape, with the diameter of the coils gradually increasing or decreasing along the length of the spring. They offer variable stiffness and deflection characteristics, making them suitable for applications where space is limited or varying force requirements exist.
Barrel Springs: Barrel-shaped compression springs have a larger diameter in the middle and smaller diameters at the ends, resembling the shape of a barrel. They provide higher stability and resistance to buckling under compression, making them suitable for applications requiring high loads or where stability is crucial.
Hourglass Springs: Hourglass compression springs have a narrow middle section and wider ends, resembling the shape of an hourglass. This design allows for increased deflection with reduced solid height compared to other types of springs, making them suitable for applications with limited space.
Variable-Pitch Springs: These springs have a varying pitch along their length, allowing for non-linear force-deflection characteristics. They can be designed to provide customized force profiles to meet specific application requirements.
Regarding the type of end configurations for compression springs, they include:
Closed Ends: Both ends of the spring are closed, meaning the last coil on each end is flattened or ground to provide a flat surface. Closed ends help to distribute force evenly and prevent buckling of the spring coils.
Closed Ends Not Ground: Similar to closed ends, but the ends are not ground or flattened. This configuration still provides a closed end but may not offer the same level of flatness or even force distribution as closed and ground ends.
Closed and Ground Ends: Both ends of the spring are closed and ground to provide a flat and even surface. This configuration ensures precise alignment and even force distribution, making it suitable for high-precision applications.
Open Ends: The ends of the spring are left open, with no flattening or grinding. Open ends allow for slight lateral movement of the spring coils and are suitable for applications where flexibility or lateral deflection is required.
Each type of compression spring and end configuration offers unique benefits and is selected based on factors such as load requirements, space limitations, deflection characteristics, and environmental conditions.
