Vääntöjousi

Vääntöjousi, also known as a torsion spring in English, is a mechanical device designed to store rotational energy and exert torque. It is a type of spring that operates by being wound or unwound around an axis. When a torque is applied to the spring, causing it to twist, it stores potential energy. This stored energy is then released as a counteracting torque, attempting to return the spring to its original position.

Vääntöjouset are typically made from a coiled wire, often steel, that is bent into a helical shape. The ends of the spring are usually shaped to engage with other components, allowing the applied torque to be transferred effectively. The direction of the winding can be either clockwise or counterclockwise, depending on the application's requirements.

Common applications for vääntöjouset include clothespins, garage doors, and various types of hinges and levers. In clothespins, they provide the necessary force to grip laundry. Garage doors utilize them to counterbalance the weight of the door, making it easier to lift and lower. They are also found in automotive suspension systems, electronic devices, and even in musical instruments. The design and material of a vääntöjousi are crucial for determining its torque, deflection, and lifespan. The amount of torque a vääntöjousi can produce is directly proportional to the angle through which it is twisted.
