Abstract
A retention device for maintaining a first rotary machine component axially loaded onto a second rotary machine component in a fixed axial position includes a lock block sized and configured to move between first and second aligned recesses in the first and second rotary machine components. The aligned recesses are shaped to prevent rotation of the lock block, and the lock block has a threaded bore extending therethrough. An actuator is threadably mounted in the bore, such that rotation of the actuator will, in use, move the lock block from the first aligned recess at least partially into the second aligned recess.
