Abstract
Pairs of cylindrical rolling pin elements are disposed in mating nests between blade dovetails and disk posts in a gas turbine engine rotor assembly. During periods of change of disk rim elastic strain caused by changes in rotor speed, relative movement between the blade dovetails and disk posts is afforded through rolling contact of the pin elements. High pressure load slippage between conventional pressure face portions of dovetails and posts and resultant fretting wear damage is obviated. Multiple pairs of pins and nests and pins of other than cylindrical geometry are also contemplated.
