The torsion spring is one of the spring types with the most complex design principle among all types, and its variations in form are also quite diverse. Therefore, the theories involved in its design are also quite complicated. Torsion springs are widely used in industries such as computers, electronics, household appliances, cameras, instruments, doors, motorcycles, harvesters, automobiles, and so on. It is one of the spring types with the most complex design principle among all types, and its form variations are also quite diverse. The theories involved in its design are also very complicated. So, what is the working principle of the torsion spring?

When a torsion spring is in use, its ends are fixed to other components. When the other components rotate around the center of the torsion spring, the spring pulls them back to their original positions, thereby creating a rotational force. This rotational force is then transformed into the desired resistance. Thus, the torsion spring can fix a certain device in a static manner by storing or releasing this energy, achieving the desired outcome.

Of course, the application areas of torsion springs are different, and the number of turns also varies. Therefore, this involves a large amount of physics and mathematics knowledge. We can calculate the number of turns required for the torsion spring by fixing the required resistance of the device. Moreover, during the calculation process, the rotation direction of the torsion spring should be designed according to the actual requirements of the application.
