What Is a Torsion Spring?
Torsion Spring is one of the more complex design principles in all spring categories, and the type changes are also quite lively, so the theory involved in design is also the most cumbersome.
- Torsion springs are helical springs. The ends of the torsion spring are fixed to other components, and when the other components rotate around the center of the spring, the spring pulls them back to the original position, generating a torque or rotational force. The torsion spring can store and release angular energy or statically fix a device by rotating a force arm about the central axis of the spring body. These springs are usually tight, but there is a pitch between the coils to reduce friction. They create resistance to rotation or rotational external forces. According to the application requirements, the rotation direction (clockwise or counterclockwise) of the torsion spring is designed to determine the rotation direction of the spring. The coils are either tightly or separately spaced, and are suitable for torsional loads (at right angles to the spring axis). The end of the spring can be wound into a hook shape or a straight twist arm. [1]
- When the spring is twisted, the material is stretched or sheared, such as the calculation of torsion. Therefore, the limit of the twistable angle is caused by the failure of the material. When the material is plastically deformed, the original state cannot be restored. So it comes down to material
