COMPRESSION SPRINGS

Springs are mechanical devices designed to store and release energy, resist forces, or maintain tension in systems. They come in various types, with compression, extension, and torsion springs being the most common. Each type is suited to specific applications and operates based on unique mechanical principles.

COMPRESSION SPRINGS

Compression springs are open-coil helical springs designed to resist compressive forces and return to their original length when the force is removed.

Characteristics

• Made from round, square, or rectangular wire.
• Typically cylindrical but can also be conical, barrel-shaped, or other custom designs.
• Operates by shortening under load and returning to its original length when the load is removed.

Applications

• Automotive: Suspension systems, valve springs.
• Industrial: Shock absorbers, vibration dampers.
• Consumer Products: Ballpoint pens, mattresses.

Advantages

• Simple and reliable.
• High durability and resistance to compressive forces.
• Wide range of customization options for stiffness and size.

APPLICATIONS OVERVIEW

Spring Type                             Key Function                            Typical Applications

Compression Spring    Resists compressive forces                 Suspension systems, shock absorbers, valve springs

Extension Spring         Resists tensile forces                          Garage doors, trampolines, brake systems

Torsion Spring             Provides rotational force                    Hinges, clothespins, ratchets

Advantages of Springs

1. Energy Efficiency: Stores and releases energy effectively.
2. Versatility: Works in tension, compression, or torsion.
3. Customization: Adjustable properties for specific applications.
4. Durability: Resists repeated loading and unloading.

Considerations for Spring Selection

1. Load Requirements: Determine the forces the spring will need to handle.
2. Environment: Consider exposure to corrosion, temperature, or chemicals.
3. Size Constraints: Ensure the spring fits within the design envelope.
4. Fatigue Life: Design for long-term reliability under cyclic loads.

CUSTOMIZING SPRINGS

Springs can be tailored to specific applications by adjusting:

1. Wire Diameter: Affects spring strength and flexibility.
2. Coil Diameter: Influences load capacity and spring rate.
3. Number of Coils: Impacts stiffness and maximum deflection.
4. Material: Determines durability, corrosion resistance, and temperature tolerance.

Spring Terminology

• Spring Rate (k): The force required to compress, extend, or twist the spring by a unit distance.
• Load: The force applied to the spring.
• Deflection: The distance a spring moves under load.

EXTENSION

EXTENSION SPRINGS

Extension springs are tightly wound helical springs designed to operate with a tensile (pulling) force. They stretch under load and return to their original shape when the load is removed.

Characteristics

• Hooks, loops, or other ends are used to attach the spring to components.
• Requires initial tension to keep coils tightly wound when not in use.

Applications

• Automotive: Trunk lids, brake systems.
• Industrial: Door hinges, garage door mechanisms.
• Consumer Products: Trampolines, toys.

Advantages

• Provides controlled tension in systems.
• Durable and customizable for specific tensile loads.

• Load: The force applied to the spring.
• Deflection: The distance a spring moves under load.

TORSION

TORSION SPRINGS

Torsion springs store rotational energy and exert torque in response to twisting forces. These springs work by twisting the spring body rather than compressing or extending it.

Characteristics

• Typically wound in a helix, with arms or legs that exert force when rotated.
• Can be used in clockwise or counterclockwise directions.

Applications

• Automotive: Hood and trunk hinges.
• Industrial: Clothespins, ratchets.
• Consumer Products: Mousetraps, window shades.

Advantages

• Compact design for rotational force.
• Highly customizable for specific torque requirements.

Materials Used

• Music Wire: High-carbon steel for general-purpose springs.
• Stainless Steel: Corrosion-resistant for marine, medical, or food applications.
• Phosphor Bronze and Brass: Electrical conductivity for switches and relays.
• Alloy Steel: High strength for heavy-duty applications.
