Gearbox

Abstract

A gearbox includes a pair of housings which are respectively provided with a bearing block protruding axially from an inner surface thereof. A radial inner surface of the bearing block defines a bearing chamber for accommodating a bearing. At least one of the housings being provided with a lubricating assembly on the inner surface thereof. The lubricating assembly includes (i) an oil deflector having a radial segment extending from a radial outer surface of the bearing block in a direction away from the radial outer surface, and a circumferential segment extending from the radial segment along the radial outer surface, and (ii) a middle oil guide rib intersecting with the radial outer surface of the bearing block and being provided with, at the intersection, an oil inlet hole providing access to the bearing chamber of the bearing block. The oil inlet hole is located on a lower side of the oil deflector. The circumferential segment extends towards the oil inlet hole. And a portion of the middle oil guide rib adjacent to the oil inlet hole is located on an upper side of the oil inlet hole.
