Torsion springs are manufactured to DIN 2194 & EN13906
Torsion Springs resist external Torque with angularly deflecting ends. Contrary to its name, the Wire is subjected to Bending Stress and Not Torsional Stress. These are Close Wound Springs. After deflection, the Body Length increases and Coil Diameter reduces.
Installation :
Spring load and deflection largely depend on the type of end and installation. Every torsion spring will have two points of contact at the end and one at the arbor. While designing, the position of the contact points and their relative position should be made clear.
Types of Ends :
A great care must be taken while deciding spring ends as different types of ends and special end forming result in higher cost and frequent tool change.
Spring Materials :
Common Spring materials include Stainless Steel, Alloy Steels, Carbon Steels and some Non-Ferrous materials. NISHI also produces spring from Exotic material like Inconel X-750, Inconel 718, Nimonic 90, Monel, Nimonic, Hastelloy, Beryllium copper etc.
