According to an aspect, a shaft internal lubrication system includes a shaft body having an outer wall and a central bore defining an inner wall. The shaft internal lubrication system also includes a plurality of lubrication holes axially distributed along the central bore and fluidically connecting the inner wall and the outer wall. At least one rifling groove on the inner wall forms a lubrication flow path to two or more of the lubrication holes. The shaft internal lubrication system further includes a feed tube within the central bore operable to drip feed a lubricant to the inner wall.
