Designer and Manufacturer of Precision Springs Since 1939
Torsion springs are a type of coil or helical spring used to apply a torque or store rotational energy and subsequently release it. The two most common types are single and double torsion springs.With that being said, Diamond Wire offers a selection of torsion springs with equally lengthed legs, oriented to your prefered unloaded angles.
Torsion springs are stressed in bending during manufacture. If possible, a torsion spring should always be loaded in a direction that causes the body diameter to decrease. The residual forming stresses are favorable in this direction, but unfavorable when the spring is loaded in a direction that increases body diameter.
Unless there are unfavorable residual stresses in the end bends, Diamond Wire's torsion springs are normally heat-treated at a low temperature to stabilize the end positions rather than fully stress-relieve them. If the direction of loading tends to increase body diameter, our torsion spring maker would typically stress-relieve the springs.
They are also used as couplings between concentric shafts such as in a motor pump assembly. Torsion springs are generally mounted around a shaft or arbor, and must be supported at three or more points.
