Choosing Between Mechanical and Gas Technical Springs

Springs are an essential component in many mechanical and technical systems. Their ability to store and release energy makes them useful in various applications, including automotive, aerospace, medical, and industrial machinery. When selecting a spring for a specific application, mechanical and gas technical springs are two of the most common options. This article will explore the factors to consider when choosing between these two types of springs.

Mechanical Springs

Mechanical springs, also known as coil springs, store energy by deforming under the influence of an external force. When the external force is removed, the spring returns to its original shape, releasing the stored energy. Several mechanical springs include helical springs, leaf springs, and torsion springs.

Helical Springs

Helical springs are the most common type of mechanical springs. They are made from a wire wound into a coil shape, and the wire’s diameter and the number of coils determine the spring’s stiffness. Helical springs are used in various applications, including suspension systems, valves, and mattress foundations.

Leaf Springs

Leaf springs are a type of mechanical spring commonly used in suspension systems, such as those found in trucks, trailers, and railway cars. They consist of several layers of metal plates bolted together and can support heavy loads without losing shape or function.

Torsion Springs

Torsion springs store energy by twisting or rotating. They are commonly used in applications requiring a rotational force, such as door hinges and clothespins.

Gas Technical Springs

Gas technical springs, also known as gas springs, use compressed gas, usually nitrogen, to store and release energy. They are commonly used in applications requiring constant force over a long distance, such as car hoods, hospital beds, and office chairs. There are two types of technical gas springs: compression and tension.

Compression Gas Springs

Compression gas springs work by compressing the gas inside the cylinder, which generates a force that pushes the piston and extends the spring. They are commonly used in applications requiring lifting or lowering heavy objects, such as automotive ones.

Tension Gas Springs

Tension gas springs work by extending the gas-filled cylinder, which generates a force that pulls the piston and compresses the spring. They are commonly used in applications that require a constant force in one direction, such as in the medical industry.

Factors to Consider When Choosing Between Mechanical and Gas Technical Springs

Several factors should be considered when selecting a spring for a specific application to ensure optimal performance. These factors include load capacity, size, cost, operating environment, and performance.

Load Capacity

Load capacity refers to the maximum weight that a spring can support without losing its shape or function. Mechanical springs generally have a higher load capacity than technical gas springs. This is because mechanical springs are made from high-strength materials, such as steel, while technical gas springs rely on the pressure of a gas to provide the necessary force.

Size

Size is another critical consideration when selecting a spring for a specific application. Gas technical springs are generally smaller than mechanical springs and require less operating space. This makes them ideal for applications where space is limited, such as in the automotive industry.

Cost

Cost is an important factor to consider when selecting a spring. Gas technical springs are generally more expensive than mechanical springs due to their specialized manufacturing processes and materials. However, their superior performance in certain applications often justifies the increased cost.

Operating Environment

The operating environment of spring is an important consideration. Mechanical springs are more durable and can operate in various temperatures and conditions. On the other hand, technical gas springs are sensitive to temperature and pressure changes and may require additional maintenance to ensure optimal performance.

Performance

The performance of the spring is a critical consideration when choosing between mechanical and gas technical springs. Gas technical springs provide a constant force over a long distance, making them ideal for applications that require precise and consistent movement. For example, in the automotive industry, technical gas springs are commonly used to assist in the opening and closing car hoods and trunks. On the other hand, mechanical springs are better suited for applications requiring rapid acceleration and deceleration. For example, mechanical springs are commonly used in the aerospace industry in landing gear systems.

Choosing the Right Spring for Your Application

When selecting a spring for a specific application, it is important to consider its requirements carefully. Here are some factors to consider:

• What is the load capacity required?
• How much space is available for the spring?
• What is the operating environment, including temperature and pressure?
• What level of performance is required, including the speed and force of the movement?
• What is the budget for the spring?

Answering these questions allows you to narrow your options and choose the spring that best meets your application’s requirements.
