Torsion spring is an essential coil spring in mechanical and electronic industries. It can store and release angular energy, or rotate the force arm around the spring body's central axis to fix a device statically. The end of the torsion spring is fixed to other components. When the other components rotate around the spring center, the spring pulls them back to their original position to produce torque or rotating force.

1、 What should be paid attention to in torsion spring configuration? Torsion springs are designed so that the coils are in close contact with each other in order to promote rotation and produce angular resilience. There are many kinds of arm configurations that can hold the spring in different ways. For torsion spring, the force arm specifications that must be considered include arm angle, arm length and arm closing type. When the spring is straight or parallel on the same side, the angle of force arm is regarded as 0 ° and the angle increases along the non rotating direction. The types of arm closing include straight twist, straight line offset, hinge, short retractor and retractor. To meet the application requirements, you can bend, twist, or make the closure of the torsion spring into a hook or loop.

2、 What parameters must be paid attention to when selecting torsion spring?

1. The thickness of the spring line should be selected according to the size of the spring force required by the individual. It is usually represented by the letter D.

2. Also know the section diameter of the torsion spring.

3. The natural length of the torsion spring and the maximum torsion angle of the torsion spring are how many. The service life of the torsion spring can be extended only by calculating the maximum force that the torsion spring can support.

4. We also need to know how much the maximum load of different torsion springs is, and then we can select springs according to their own needs.

5. Special attention should be paid to the spiral direction of the spring, which is the most common error area in our daily life. People often remember the direction rotation incorrectly. So this has to be remembered.
