Torsion Springs

It is a spring that works by means of torque (rotational force). Its ends (legs) rotate around the spring axis, exerting rotational pressure.

It is used to store and release angular energy or to statically maintain rotational pressure on a shaft.

When one leg is rotated relative to the other, the spring attempts to return to its original angular position. The more it is rotated, the greater the force it exerts.

It is calculated based on the torque (moment), usually expressed in N/mm. Factors include wire diameter, inner diameter, number of coils and leg length.

Carbon steel and stainless steel, capable of withstanding repeated torsion without permanent deformation.

It is the range of degrees through which the spring can rotate. It is vital not to exceed the maximum design angle to prevent breakage or loss of force.

You must know the required torque and the diameter of the shaft on which it will be mounted, as the spring reduces its inner diameter during operation.

Unlike linear springs (extension/compression), it works with circular or rotational movement.

Yes, in fact this is the most common approach, as the shape and angle of the legs must perfectly match the anchoring system of each machine.

In clamps, door hinges, control mechanisms, automatic closures and watchmaking or automotive systems.
