The power spring is made of strip material and typically installed between an inner shaft and an external housing. A torque is generated between the inner shaft and the external housing.
The number of turns is individually determined and can be as much as 50. Different coiling techniques exist to give the material the desired curvature that matches the torque-rotation requirements. The spring has many similarities with clock springs, but have a much larger operating range in terms of number of turns.
A power spring can be used for winding cables, hoses, safety belts and much more.
Maximum strip thickness 2 mm
