LUBRICATION SYSTEMS FOR GEARBOX ASSEMBLIES

摘要

A gearbox assembly includes a housing with a housing interior. A sump is disposed within a lower region of the gearbox housing. A lubricated transmission element is arranged in the housing interior above the sump. A lubricant impoundment is arranged within the housing and in series between the transmission element and the sump such that lubricant flowing in a primary lubricant flow path between the transmission element and the sump is impounded in the lubricant impoundment, thereby providing a supply of lubricant for a secondary lubricant flow path disposed within the gearbox housing.

1. A gearbox assembly, comprising:
a housing with an interior and a sump which holds lubricant; a transmission element disposed within the interior and above the sump which receives and is lubricated by the lubricant; and a lubricant impoundment disposed between the transmission element and the sump, wherein the lubricant impoundment is connected in series between the transmission element and the sump in a primary lubricant flow path through which the lubricant held in the sump reaches the transmission element, and wherein the lubricant impoundment maintains a supply of lubricant having passed through the transmission element for a secondary lubricant flow path other than the primary lubricant flow path and disposed within the gearbox housing through which the lubricant held in the lubricant impoundment reaches the transmission element.
