Lee Spring offers several different types of spring to suit many different kinds of application including Torsion Springs. A Torsion Spring is spiral shaped and exerts a torque or rotary force. Like an extension spring, each end of a torsion spring is attached to another component. The components rotate around the centre of the spring and then the spring tries to push them back to their original position.
Torsion springs are actually subjected to bending stress as opposed to torsional stress and can store and release angular energy or statically hold a mechanism in place by deflecting the legs about the body centre line axis.
As a torsion spring is wound up, it reduces in diameter and its length increases, which is important to consider when design space is limited. The best application for a Torsion Spring is when it is supported by a rod or tube.
The sizes of torsion springs available from Lee Spring, begin at miniature, used in electronic devices, and go up to large, which are used in chair control units.
Torsion springs are used for hinges, counterbalances and lever return applications. Typically, the applications torsion springs are used for include clothes pins, clipboards, swing-down tailgates and garage doors.
