GEARBOX LUBRICATION SYSTEM

摘要

A high speed gearbox includes a housing which encloses a rotating gear and a volume which contains oil and air. The gear has an outer first surface exposed to the volume and has a second surface exposed to the environment. A vent arrangement includes first and second passages formed in the gear. The second passage extends axially part way into the gear and has an outer end exposed to the second surface. The first passage extends radially from the first surface to the second passage. A check valve is mounted in the second passage and permits one-way flow of air from the volume to the environment.

1. A rotary machine lubrication assembly, comprising:
a housing enclosing a volume which contains oil; a first part mounted for rotation in the housing, the first part having a central hub and a flange which projects outwardly from the hub; an annular bearing is mounted on the hub; a second part mounted on the bearing for rotation in the housing; and a first passage formed in the first part, the first passage directing oil from the volume to a peripheral surface of the hub and to the bearing upon rotation of the first part.
