ABSTRACT:
A lubrication device in a transmission in which change-speed gears rotatable on a hollow shaft are arranged to be supplied with lubricating oil through an axial blind bore in the shaft. The lubrication device includes an oil collector mounted in a casing assembly for the transmission and located above an open end of the axial blind bore in the shaft to receive lubricating oil picked up in the casing assembly, an oil feed pipe extending from the collector into the open end portion of the bore, and a pump impeller assembly mounted in the open end portion of the bore to impel the lubricating oil from the feed pipe toward the closed end of the bore during rotation of the hollow shaft.
