Abstract
A propeller shaft assembly includes a propeller shaft extending along an axis between a first and second shaft end. A propeller shaft yoke is operably connected to one of the first or second shaft ends and includes a body presenting a mounting surface extending circumferentially about the axis. A tuned damper extends radially outwardly from the mounting surface and includes a first damper ring disposed in abutting and encircling relationship with the mounting surface and a second damper ring disposed in abutting and encircling relationship with the first damper ring. The tuned damper includes a retention lip extending radially downwardly from the second damper ring in axially spaced relationship with the mounting hub by an axial spacing distance D for protecting the tuned damper from axial impact forces and improving the robustness of the tuned damper mounted on the mounting surface.
