MATERIALS AND PROCESSES FOR MARINE GEAR VIBRATION ISOLATION SYSTEM

Specifications for propulsion reduction gears going into DD 963 class destroyers called for structureborne vibration levels significantly lower than those previously obtained for similar, though smaller, Navy gearing. Further, weight, cost, and space considerations necessitated the design of an unconventional system which would effectively vibration-isolate the gear from its foundation. The system is made up of vertical isolators and horizontal isolators. The former are made from extrubed bar of 7075 aluminum heat treated to the T73 temper; the latter are made from 6A1-4V in the mill annealed temper.
