Abstract
A corn head row unit gearbox includes an input shaft, that rotates about a first axis of rotation and that drives a set of bevel gears. The bevel gears transfer rotation of the input shaft into rotation of a set of gathering chain output shafts about a second axis of rotation, generally transverse to the first axis of rotation. The gathering chain drive shafts each rotate within a bushing mounted within a frame structure of the gearbox. The frame structure defines a bore that communicates with a bevel gear cavity, in which at least one of the sets of bevel gears rotates, and an interior of the bushings mounted on the gathering chain drive shafts. Rotation of the bevel gears carries lubricant to an inlet aperture on the bore and drives the lubricant through the bore into the bushings.
