A frangible coupling (12) for interconnecting parts comprising a first ring (40) and a second ring (44) coaxially arranged relative to each other and axially joined via an annular array of fuse ligaments (42) equidistantly spaced apart from each other. The ligaments (42) are configured to fail when an abnormal radial load of a predetermined value causes the first and second ring (40,44) to move out of their coaxial relationship. When all of the fuse ligaments (42) are severed, the communication between the first and second rings is severed (40,44). This allows the first ring (40) to move independently of the second ring (44), preventing the out of balance load on the first ring (40) being communicated to the second ring (44). <IMAGE> |
