The torsion spring is spring, the spring torque and rotational force. At the end of the torsion spring is fixed to the other components, while other components around the center of rotation of the spring, spring back to the initial position of them.
The application of the torsion spring
The general application of torsional spring clothes pin, note: in a paper clip, the tailgate and garage door. Torsion spring also has applications in the hinge, a balance body and handle resetting device. The spring dimensions, such as micro electronic equipment for spring and spring seat for large scale controller. Should be applied to the spring load according to the rotation; not recommended position rotation spring from the free position outside. The spring rotates, shorter diameter, spring length. The design space is limited, the need to consider this point. Torsion spring rod or pipe support, work performance is the best. The designer should consider the effect of friction force and deflection of torque.
