I am looking for a formula for calculating the spring rate per inch, when stacking three compression springs. (Danly #9-1006-11) I believe the spring has a rate/inch of 120 lbs. I want to stack three of these with guides between them which slide on a core rod. The stack will be compressed .90 of...
I would like the spring to last for over 1 millon cycles if possible. I can use a Dadco nitrogen gas spring with that stroke which they say is good for 1 millon strokes minimum. I thought that a standard spring should be able to be set up to out live the nitrogen spring. there are 3 springs per...
I can increase the depth of the pocket to allow a longer spring. I feel that the increase in length will reduce the stress and help reduce the side load against the pocket. how should the spring be supported? if I put a pin in the center, it will still rub on the pin, correct?
israelkk, you are right, the sprink rate is 26lb/in for stainless steel. I incorrectly typed in the music wire rate. the pocket in the aluminum can only be 1.875 deep because the stripper bar that the other end is guided by has a pocket .20 of an inch deep. the stripper bar would crash into the...
I have a situation where compression springs are failing at an accelerated rate. the situation is a 3.00 inch long, 1/2 diameter spring. it has a rate of 31.17 LB/IN. preloaded .200 of and inch, with a working stroke of .75 inches. the solid height of the spring is 1.560 inches. the spring...
