We produce high quality made-to-order torsion springs in quantities from 1 to millions.
Helical springs used to apply a torque or store rotational energy are commonly referred to as “torsion springs”. The two most common types are single and double-bodied springs. They can store and release angular energy or statically hold a mechanism in place by deflecting the legs about the body centerline axis. They offer resistance to twist or rotationally applied force. Torsion springs are generally mounted around a shaft or arbor and must be supported at three or more points. The legs can be at any position and have virtually any bend twist or loop in them. The stress is in bending not in torsion. If possible a torsion spring should always be loaded in a direction that causes its body diameter to decrease as force is applied. The residual forming stresses are favorable in this direction but unfavorable when the spring is loaded in a direction that increases body diameter. Depending on the application torsion springs can be designed to work in a clockwise or counter-clockwise rotation, thus determining the direction of the wind. This type of wire spring is most often used with forces of rotation similar to those found in a motor or drive unit with a rotating shaft or something as simple as a clothespin. In either application the wire is formed to provide resistance to torque, thus the name torsion spring.
