Different types of springs & their uses | Skill-Lync

Summary

The video explains what springs do, why they are used, and six major spring types.

A spring is a mechanical device that changes shape when a load is applied and returns to its original shape when the load is removed. Depending on its design, it can pull, push, wind, support, or lift. Springs store energy while they are deformed and release it as they recover. They are found in many everyday items, including beds, watches, remotes, vehicles, and garage doors.

Types of Springs

• Helical springs

  • Shaped like a helix and commonly used in vehicle suspensions.
  • Can store energy when compressed and withstand pulling forces.
  • Two types are described:
    • Closed-coil helical springs: Coils are arranged at an angle of less than 10 degrees. They are used where stretching must be resisted, such as in garage-door assemblies and vise-grip pliers.
    • Open-coil helical springs: Coils are arranged at an angle greater than 10 degrees. Also called compression springs, they resist compression and are used in items such as auto injectors and ballpoint pens.

• Torsion springs

  • Similar to a closed-coil helical spring, but with ends extending away from the spring’s axis.
  • Store twisting force and exert torque that helps return the spring to its original position.
  • Examples include clothespins, mousetraps, and door hinges.

• Conical and volute springs

  • Conical springs: Similar to helical springs, but their shape allows them to compress more. Examples include battery contacts in remote controls and garden actuators.
  • Volute springs: Similar to conical springs; as they compress, smaller coils slide inside larger ones. They are used where large compressive forces must be applied over a small area.

• Laminated or leaf springs

  • Made from layers of metal arranged one over another and secured with bolts, nuts, or clamps.
  • Used in cars and larger vehicles to absorb the impact of bumps and road undulations.
  • The video notes that leaf springs are preferred over helical springs in heavy vehicles because they are more stable under those conditions.

• Disc or Belleville springs

  • Disc-shaped springs used in bolted connections.
  • Help prevent a screw or bolt from vibrating loose.

• Special-purpose springs

  • Used for particular applications rather than widely across everyday devices.
  • Examples given:
    • Air springs: Used in vehicle suspension systems.
    • Gas springs: Used to damp forces and return kinetic energy.
    • “Greater” springs: This term appears in the subtitles; these springs are used in oil seals and electrical connectors.
