Tension spring

Tension spring

In the manufacturing industry, springs are used in various designs and shapes for different projects. Each type of spring has a specific purpose and function to maximize its potential. The tension spring is one of the types of springs that we provide complete explanations about in this article.

The tension spring is used in various industries. Two hooks are attached to both ends of this type of spring, which can be attached to objects or parts. The rings that make up the tension spring are often placed together without a gap. As the name of tension spring suggests, this type of spring works with tension force. This means that the tension force enters the spring from both ends and causes the rings of the tension spring to move apart. After the tensile force is applied from the sides, the spring uses the stored force to apply the reverse force and return to the initial state. In fact, this spring is used to keep the two mechanisms close to each other.

Application of tension spring:

As mentioned, tension springs have various uses. Some of the most common uses of tension springs are:

1. The automotive industry
: Tension springs are used in various parts of cars, both external and internal. The car carburetor is one of the most important components in which the tension spring is used.

2. Garage door:
As you know, garage doors weigh a lot and are relatively difficult to open and close. By using the tension spring in the garage door, this process is greatly facilitated.

3. toys:
Tension springs are used in many toys, especially those with tossing and bouncing functions. The springs used in these toys are usually small.

4. Trampoline:
One of the factors that increase the flexibility and jumping potential of a trampoline is the presence of tension springs.

5. Agricultural machinery: tension spring is used in many parts of agricultural machinery.

6. medical tools:
Medical instruments such as operating room lights and many other medical equipments have a tension spring in their mechanism.

 

 

Types of tension springs

As mentioned, tension springs are equipped with two hooks or rings at both ends of the spring to connect the tension spring to other mechanisms. These rings have different types, each of which has specific uses. Cross ring, D-shaped ring, machine ring, angled ring, full edge ring, drawn ring, drawn round ring etc. are some of them.

Fatigue in the tension spring

Fatigue in the tension spring often occurs due to the tension created through the tension force applied from the two ends of the spring for a long period of time. Tension springs do not perform as well as compression springs in fatigue applications and their resistance is lower than compression springs, and many end rings of tension springs are geometrically designed and manufactured in such a way that they bear a lot of stress due to severe bending.

The difference between tension spring and compression spring

The tension spring and the compression spring are very similar in appearance, and this issue causes them to be confused. The main difference between tension spring and compression spring is in the method of applying load.

The tension spring rings are located at a small distance from each other. In the tension spring, the tension force enters from the two ends of the spring and causes the rings to separate from each other. In this way, after applying the tensile force, the spring returns to its original state by using the stored force and by applying the reverse force.

The force applied in the compression spring is just opposite to the tension spring. In other words, the compression spring works by using compression force. The tension spring rings are relatively separate from each other. In this way, the external pressure force applied to the spring makes the spring rings closer to each other. The spring then uses this force to return to its initial state and separates the spring rings from each other.
