Abstract

A breather structure for a reduction gear in which a plurality of stop ribs are disposed within a housing. The stop ribs are disposed at nonuniform distances between successive ribs in order to prevent oil from entering a breather chamber of the housing. The relative spacing between successive ribs allows the breather structure to prevent oil traveling at varying speeds from entering the breather chamber. The ribs have an upper surface which is disposed at declining, or obtuse, angles with respect to an interior of the housing, and a lower surface which acts to receive oil rising from a bottom of the housing.
