Talk:Coil spring

Applications
Under the applications heading should I add in things such as car suspension and valve springs with a little descriptive paragraph under each? TLL3 (talk) 15:23, 18 April 2018 (UTC)

sandpit experiment
coil sprin is the best because its round and it can have pressure and other things on it —Preceding unsigned comment added by 195.195.244.161 (talk • contribs) 10:42, 19 January 2007

Springs need to be tested before installing. —Preceding unsigned comment added by 202.56.227.60 (talk • contribs) 11:29, 18 February 2007

braided wire springs?
I have seen a number of coil-type springs made from two or more strands of wire braided together. Supposedly the advantage this confers is that the spring will be more resilient under sudden extreme shocks and less prone to breakage. I don't know how common they are or whether they're noteworthy enough to mention here. —Preceding unsigned comment added by 69.41.40.21 (talk • contribs) 04:06, 29 April 2007

Double :-)
There seems to be some overlap between this article and this one:http://en.wikipedia.org/wiki/Spring_(device)

I'm not sure how that should be fixed, but at least i've put it out there now :-) —Preceding unsigned comment added by 81.28.84.247 (talk) 14:36, 19 May 2009 (UTC)

There also seems to be overlap with (but no cross reference here to) Torsion spring. And what about Spring steel, the material from which many springs are presumably made? Iph (talk) 21:22, 28 December 2014 (UTC)

coil springs
why coil springs are always circular in shape —Preceding unsigned comment added by 210.212.170.226 (talk) 11:53, 5 October 2010 (UTC)


 * Because that equalises the stresses in the wire. Greglocock (talk) 23:43, 6 October 2010 (UTC)


 * They don't always have a circular cross-section; die springs use a square cross-section. Wizard191 (talk) 12:14, 7 October 2010 (UTC)


 * Hang on are we talking about the wire or the general form of the spring? Greglocock (talk) 23:36, 7 October 2010 (UTC)


 * I figured the user had to be refering to the cross-section, because, by definition, a "coil spring" is in the form of a "coil" or a helix. Wizard191 (talk) 00:34, 8 October 2010 (UTC)


 * Wait a moment. If the wire is wrapped around, for example, an elliptical or rectangular form to make a spring for a certain purpose--perhaps one that must fit within a narrow slot--is it therefore no longer a coil spring?  — Preceding unsigned comment added by 68.61.164.169 (talk) 00:28, 29 August 2014 (UTC)

Editing external links
Changes:

1. The tutorial How to make springs is excellent; I added Silberstein's name, which is hard to find on his site.

2. Website for Chamberlain Spring has moved, due to merger with McAllister Spring, & is now useful mostly for its glossary.

3. Muelles site doesn't seem to me to have enough useful info to warrant an External Link. Oaklandguy (talk) 21:43, 26 August 2011 (UTC)

How many variants?
The Variants section currently says there are two usual variants, and then proceeds to list three, the third without any citation, explanation or examples as to what exactly it is and how it differs from the other two. The edit that added this is almost a year old, by an anonymous IP with no other edits, which casts doubt as to its reliability. I did a cursory Google search for the term and didn't get any obvious hits, so is it safe to say that this can be removed? Lurlock (talk) 14:19, 22 October 2011 (UTC)

non-helical coil springs?
I have seen in certain applications a type of spring that is made of a narrow, thin strip of steel wound around a central axis in the manner that tape is wound onto a reel. In the applications I have seen, unrolling the strip puts it in tension which is released when it rolls itself back up onto the central axis.

Is this regarded as a variant of coil spring, or a variant of leaf spring? Or is it something unique that has its own terminology? I have found them inside certain types of mechanical devices but even diagrams from the manufacturer label the part only as "spring." — Preceding unsigned comment added by 69.41.40.24 (talk) 16:28, 21 June 2012 (UTC)
 * Have you had a look at constant-force spring? It's only a stub, I'm afraid. Wikipedia hasn't got to grips with the negator spring yet, but it's described in this magazine article—how to make a talking doll—and has been the subject of very many patents, some of which have been placed online by Google. Otherwise, you could try the reference desk. If negator spring turns out to be the answer, and you manage to collect some information about it from some useful sources, how about fixing the gap in Wikipedia as your first article?--Old Moonraker (talk) 17:12, 21 June 2012 (UTC)

Metal/material used to make springs
I think the article should discuss/explain the material. Can any kind of steel used? Does a spring not need to be of a certain kind, in order to retain its springiness, and not just change its shape, as (say) lead and to some extent copper do, rather than be springy when used around large forces/pressures? The article Torsion spring also says nothing about this. Plain copper is pliable like modelling material but what of alloys of it, and other metals? I am thinking of names like phosphor bronze.

Merge proposal
An editor has suggested we merge this with spring. Actually discussed over there, not here.
