Low strength belleville washers
 

Anyone know of a source of really thin / low thrust belleville washers?
....I'd like to find some about the same strength as a few wave washers...
But they don't seem to exist.

Well I don't know about really thin/ low thrust but I have bought disc
springs from these guys http://www.springmasters.com/ . They are in the
UK but might give you some idea.

Check with these folks:

They offer bellevilles with slots cut into the ID to reduce spring rate.
I've only noticed them in their literature when purchasing other disc
springs from them, so I'm not sure if they're a standard product or not.

I have used their serrated bellevilles, which are sized to fit under the
heads of socket cap screws and are thinner than typical, so might be
worth a look as well.

You can put the washers in series to reduce their effective
spring rate. You put them on alternating up and down.

The rate/distance will decrease, as you are increasing the max distance
of travel allowed. Or to look at it differently, when you make space and
double the springs this way, and keep your initial compression distance
the same, you cut the actual compressed distance of one spring in half.

For a comprehensive selection of belville springs, and any other spring
you can imagine, look at these guys:

Good folks to deal with.

Lacking a source for the particular thrust you need, you might anneal some
spring stock, "coin" your own washers, then re-temper them. It's not as
difficult nor time-consuming as it sounds.

Surprisingly, most hardware stores sell very thin spring washers in both
wave and Belville styles. If the thrust (or travel) of the thin washer is
not sufficient, you can stack them (in parallel, or all stacked the same
way) to increase thrust, or in series (face to face and back to back) to
increase travel.
