Torsion springs are helical coil springs that have ends that are rotated in angular deflection.
These springs offer resistance to an externally applied torque -
energy is absorbed and stored when torsion springs are twisted. Torsion
springs are manufactured with many different configurations to suit the
required location points.
Torsion springs have a variety of uses, including mining equipment, slip drive clutches, agricultural implements to door closing
devices.
