Torsion springs can be used for gripping around a shaft.
D: I want many cycles of life (High Repeat Ability). How do I achieve this? In order to do this, one must understand the Logics of Torsion springs.
If you are looking to design your torsion spring online Planetspring.com has just the thing. We have one of the few torsion spring calculators available on the web today. With three simple inputs you have a spring rate calculation, spring constant, as well as 11 other values. You can also see an example of a torsion spring if you are not sure what one looks like.

Outside diameter: The outer diameter of a spring.
The actual operating environment of the spring wire plays a large role. Many coatings are available that can greatly reduce corrosion. These include powder coating and Phosphate with an oil dip or spray. Additionally there are many types of economical plating solutions available.
The following are just a few of the most basic formulas for spring design & calculating spring constant on compression spring design. Please bear in mind that effective coil spring design can only be accomplished by using a computer program capable of running hundreds of simultaneous calculations. If you need to calculate your compression spring please visit the compression spring calculator page from the home page of Planetspring.com
Free Length: The overall length of a spring in the unloaded position.
Will the compression spring operate under static or cyclic environments? If cyclic, what are the minimum and maximum operating loads, deflections (travel) or heights? What is the life you want from the compression spring? Where is the operating environment? What is the operating temperature? Will it be a small spring? Will it go into a hole or around a shaft and if so what is the size of each? These are the questions you need to ask yourself before calling compression spring suppliers.
