What should I pay attention to when choosing a torsion spring?

The torsion spring is an indispensable coil spring in the mechanical and electronic industries. The torsion spring can store and release angular energy or statically fix a device by rotating the force arm around the central axis of the spring body. The ends of the torsion spring are fastened to other components, and as the other components rotate about the center of the spring, the spring pulls them back to their original position, generating a torque or rotational force.

What should be paid attention to in the configuration of the torsion spring? A torsion spring is designed with its coils in close contact with the intent of promoting rotation and allowing it to generate an angular return force. There are several options for lever configuration, which can hold the spring in different ways. For torsion springs, the arm specifications that must be considered include arm angle, equal arm length, and arm closure type. When the springs are straight or parallel on the same side, the arm angle is considered 0° and the angle increases along the non-rotational direction. Types of arm closures include straight twist, linear offset, hinged, short hook closures and hook closures. To satisfy the application rules, you can twist, twist the end of the torsion spring, or make it a hook or loop.

2. What parameters must be paid attention to when choosing a torsion spring?

1. The thickness of the spring wire should be selected according to the size of all necessary spring elastic forces. Generally represented by the letter d.

2. It is also necessary to understand the diameter of the cross-section of the torsion spring.

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

4. It is also necessary to understand the maximum load of different torsion springs, and then you can choose the spring according to your own needs. Metal extension spring

5. Special attention should be paid to the spiral direction of the spring. This is the most common mistake area in our daily life. People often misremember the direction of rotation. So it is necessary to keep this in mind.
