Abstract
A ring designed to support instrumentation modules on the rotor of a rotary machine and to withstand centrifugal accelerations significantly in excess of 500 g comprises two half-rings made of zicral (AZ5GU) alloy clamped to the rotor shaft. In order for the ring to remain attached to the shaft at speeds up to and in excess of the maximum speed thereof, there are formed in the cylindrical perimeter of the ring a central groove and two side grooves. A tape of glass fibers impregnated with a polymerizable resin is wound on under tension in superposed layers, initially into the central groove and then into the side grooves. The wound tape is then immobilized under tension by polymerizing the resin.
