Friction Joint
Friction Joint
(OP)
I don't have any experience in clutch design, and I'm looking for some material recommendations to improve the performance of a friction joint.
I have a custom friction clutch designed for an application that currently uses alternating disks (about 1.5" dia) of stainless steel and delrin. Tension is held on the clutch pack using a compression spring. I'm using about 7 clutch pairs and ~5-10lb of force on the spring. I know I can increase the # of clutchs or the force, but I'd like to improve the performance by changing the materials. The clutch only has to have a relatively short life (~30,000 cycles), but I'd like to get consistant performance.
Any ideas?
Thanks,

For most consistent performance, keep ratio of inside contact dia to outside contact dia as large as possible.
For longevity, keep PV low. Increase capacity by no. of discs and contact dia.
