Abstract

According to an aspect, a shaft internal lubrication system (200) includes a shaft body having an outer wall (208) and a central bore (204) defining an inner wall (206). The shaft internal lubrication system (200) also includes a plurality of lubrication holes (210) axially distributed along the central bore (204) and fluidically connecting the inner wall (206) and the outer wall (208). At least one rifling groove (212) on the inner wall (206) forms a lubrication flow path to two or more of the lubrication holes (210). The shaft internal lubrication system (200) further includes a feed tube (222) within the central bore (204) operable to drip feed a lubricant to the inner wall (206).
