Introduction to Types of Extension Springs

Side Hook Extension Spring: Each end has a side-facing hook, making it easy to hook or secure.

Cross Hook Extension Spring: Each end has a crossed central hook, with the top and bottom hooks being in a vertical position. It is suitable for extension spring testing that requires a larger contact surface area.

Half-Circle Hook Extension Spring: Each end has a small half-circle hook, used for special small-scale equipment applications.

Long Hook Extension Spring: Each end has a hook extended after straightening the line, used for fixing larger and longer equipment.

 

Movable Hook Extension Spring: This extension spring has hooks at both ends that are designed to rotate freely. This design increases the flexibility of the spring, making it suitable for use in various special equipment where it can perform its function effectively.

Introduction and Application of Springs Used in Bicycles

Types and Principles of Bicycle Springs

Common types of bicycle springs are as follows:

  1. Coil Springs:

    Principle: These springs absorb vibrations through the compression or extension of the coils.

    Advantages: Simple structure and low cost.

    Disadvantages: Slower rebound speed, which may not be sensitive enough for high-speed riding or off-road terrain.

  2. Air Springs:

    Principle: These springs use the elasticity of compressed air to absorb vibrations.

    Advantages: The spring stiffness can be adjusted by changing the air pressure, making it suitable for different rider weights and riding styles.

    Disadvantages: Regular pressure checks are necessary, and the spring is sensitive to temperature changes.

  3. Hydraulic Springs:

    Principle: These combine oil damping with the characteristics of a spring to provide better damping effects.

    Advantages: Adjustable damping, offering more precise control.

    Disadvantages: Complex construction and higher cost.

Applications of Bicycle Springs

  1. Front Fork: Most mountain bikes and some road bikes are equipped with springs in the front fork to absorb vibrations from the road, protecting the rider's wrists and shoulders.

  2. Saddle: Some comfort bicycles have springs in the saddle to enhance riding comfort.

Types of Torsion Springs: JS Metal offers a variety to meet customer needs.

Introduction and Applications of Torsion Springs

Introduction to Torsion Springs:

Torsion springs, also known as twist springs, are divided into single torsion springs and double torsion springs. They store mechanical energy through twisting or rotational motion. When external force is applied to twist, the torsion spring generates a reverse torque proportional to the twist angle. This type of spring is widely used in various fields and everyday applications.

Types of Torsion Springs:

  • Single Torsion Spring: The coil is wound in a single direction, suitable for smaller torque.

  • Double Torsion Spring: The coil is wound in both directions, suitable for larger torque.

Applications of Torsion Springs:

The applications of torsion springs are vast, ranging from everyday items to precision instruments, they are everywhere.

For example:

  • Everyday items: Clothes pegs, door chains, hinged lids, various household items, computer printers, office machine parts, etc.

  • Industrial applications: Automotive parts, robots, medical equipment components, electrical switches, aerospace applications such as control systems and shock absorbers, etc.

  • Toys, musical instruments' internal hardware components.

Conclusion:

As a common type of spring hardware, torsion springs play an essential role in both modern industry and everyday life. Despite their simple structure, their versatile applications and outstanding performance make them a top choice for designers and engineers.

Introduction to Extension Springs

 

  1. Spiral Structure: Extension springs are made by coiling spring steel or stainless steel wire into a spiral shape.

  2. Tight Coils: In the absence of external force, the coils of an extension spring are typically in close contact with each other.

  3. Tensile Force: When the two ends of the spring are pulled apart, they generate an opposing tensile force.

  4. Initial Tension: Extension springs have an inherent tension between the coils, even when no external force is applied. This is known as the initial tension.

  5. Elastic Recovery: When the external force is removed, the extension spring can return to its original shape.

  6. Versatility: The shape, size, material, and spring constant of an extension spring can be customized to meet different application requirements.

Applications of Extension Springs

The applications of extension springs are very broad, commonly used in automobiles, appliances, bicycles, motorcycles, computer printers, and scanners. Essentially, many electronic devices and appliances used in daily life rely on extension springs.
