650-1100 pound torsion coil spring?
650-1100 pound torsion coil spring?
(OP)
I need a torsion coil spring rated up to 1100 lbs. but design space is limited to 4" Diameter x 48" length.
The range of motion needs to be 11 revolutions.
Is this possible? If not 1100 lbs. then what is the maximum rate spring that would fit within this size?

2. 11 revolution are not feasible by helical torsion spring.
A better description of your problem is needed. Picture will help too. What kind of torsion spring you have in mind?

This is like a garage door torsion coil spring.
It drives a shaft with an ANSI 60 chain sprocket with a 3" pitch diameter.
So I need a 1650 in/lbs torque spring.
I miscalculated on the turns, it only needs to be 3 revolutions.
