Power springs

Power springs, crafted from strip material, are commonly positioned between an inner shaft and an
outer housing. This arrangement generates a torque between the two components. Various coiling
techniques are employed to impart the desired curvature, aligning with the specific torque-rotation
demands.
While sharing similarities with clock springs, power springs possess a substantially wider operating
range in terms of the number of turns. They prove versatile, finding utility in cable and hose
winding, safety belt mechanisms, and a myriad of other applications.
