Adjustable spring rate compression spring?
Adjustable spring rate compression spring?
(OP)
I need to know how to set compression of one coil spring to 20 lbs.,40lbs. and 60 lbs. The spring will be housed in a cylinder and needs to easily be adjusted manually. Any suggestions? I'm stumped. Thanks alot.





RE: Adjustable spring rate compression spring?
If you know the spring rate, just compress the spring the distance needed to obtain that force.
For your cylinder, you could perhaps drill holes in the side at the given deflections. Then as you push the spring past that point, slip a pin in to stop the spring from returning.

Or if you were looking for somethign that had an increasing rate... Try a variable rate spring. There are tons of ways to do this, ie. varry the wire size, varry the pitch, varry the diameter...
