Helical Torsion Springs Manufacturers

Definition: Helically wound spirals forming a set of coils which make up a spring.
This spring is used to exert a rotational force therefore making this a helical torsion spring.

When a load is placed on one or both of the helical torsion spring's legs, they will travel in a rotational form. This is called torque. The function of helical torsion springs is for its legs to travel a certain amount of degrees under a certain load and for it to return to its original state once the load is released. Take the following scenario as an example:

Your spring's leg travels 45º with 1 pound of force and 90º with 2 pounds of force. To know your  helical torsion spring's rate per degree , follow the formulas below or take a look at the diagram provided to get a clearer vision of how spring rate works.

The diagram shown below shows how this formula works and shows that to get the rate per 360º you must multiply the rate per degree by 360.

k = L ÷ T

Rate = Load ÷ Travel

k = 1 ÷ 45

k = 0.02222 inch-pounds per degree

k = 2 ÷ 90

k = 0.02222 inch-pounds per degree

There are millions of configurations when it comes to your  helical torsion spring’s design

The reason for this is because of the many variables in your helical torsion spring’s physical dimensions such as the various wire diameters, outer diameters, total coils, leg lengths, direction of wind, and material types. If you have a helical torsion spring design and decide to change a certain dimension by even one thousandths of an inch (0.001”), it automatically becomes a new design because the  measurements in the helical torsion spring have changed.

Helical springs all have different types of ends

Torsion springs have legs. You see, at the end of the last coil, the spring wire becomes straight. This is considered a leg on which you can place bends, radiuses, loops or other different shapes allowing you to customize your helical torsion spring to fit in your particular product or application.  Helical compression spring ends are usually closed and squared ends, closed and ground ends, double closed ends or open ends. Helical extension springs  will have hooks and the type of hooks may vary from machine hooks, cross over hooks to even extended hooks.
