Interference fit between a bin and a cylinder
Interference fit between a bin and a cylinder
(OP)
Hi all, I have here a little problem.
Is there any way to calculate the equivalent pressure on a pin caused by an interference fit with a cylinder?
Thanks.

RE: Interference fit between a bin and a cylinder
P = [<(delta*E )/ (2*rb*rc^2)> - <(3+nu)*w^2*rho/(8*g)>] * [rc^2-rb^2]
Symbols:
(1) ra = shaft id (often 0
(2) rb = shaft od and hub id (approx)
(3) rc = hub od
(4) delta = static interference
(5) E,nu - material properties
(6) w = angular speed.
(7) g = gravitation conversion
If w=0 (stationary), then this reduces to
P = [(delta*E )/ (2*rb*rc^2)] * [rc^2-rb^2]

a = radius of inside of inner cylinder
b = raidus of outside of inner cylinder (same as inside of outer cylinder)
c = radius of outside of outer cyliner
