## Torque applied to a system with belleville springs

## Torque applied to a system with belleville springs

(OP)

This has something to do with thread404-239297: Torque (Pitch/Bolt) to Axial Force.

Hello. I'm trying to calculate the torque I need to apply to a nut so that I can obtain about 2000 kgf of axial force. I have a component that can't take more than 2000 kgf. At the same time, the sealing of the system must be guaranteed.

Does the equation T = K*D*F (in which K = 0.2) apply in this case or is it just for bolts? I know whis formula isn't very accurate, since it doesn't account for pitch, but I don't need much accuracy for this.

Also, there's a large set of belleville springs in the bottom part of the system: 6 sets in series of 3 springs in parallel (each set has 3 springs in parallel, and there are six of those in series = 18 belleville springs in total).

I was wondering if the springs somehow change the way the force is transmitted to the bottom of the system, where the delicate part is located. Since the system will be pretty much static, I believe the formula could apply.

Another way I'm thinking of determining the "torque" is by measuring the deflection of the springs.

Thank you for helping me :)

Appreciate the help!! You guys are amazing :)

It was a result of noting that minute variations in belleville springs retult in large variations in spring height at load. Even smashing them flat a few times was required to even out the forming residual stresses.
