garter spring
garter spring
(OP)
Hi!
I am trying to calculate the radial force that a garter spring makes on a shaft.
Could anyone give some information about how to design a garter spring, or how to calculate the radial force?
I have been seaerching but didnt find anything so far..
Thanks!

RE: garter spring
Look at a cross-section showing the spring around the shaft (circle in a circle). Now cut the shaft in half so it is two half-circles. The two half circles are held together by two times the spring tension (T). The contact "pressure" (actually,in this case, force per inch of diameter (D)) is 2T/D. If the shaft were a fluid, the pressure must be the same in all direction, so the radial force of the spring is also 2T/D.
You could also use calculus to show that a radial force on a cylinder resolves to the same force across the diameter.
