Abstract
A centrifugal air-oil separator system for a gas turbine engine system is described. The air-oil separator system has a rotatable shaft and the shaft includes an axially extending bore formed at least partially through the shaft. A gear is integral to or mounted on an outer surface of the shaft. The air-oil separator system also includes a bolt-on breather mounted on the shaft and independent from and in contiguous contact with the gear to assist in separating the oil from the air. Various types of materials may be utilized in the construction of the air-oil separator system.
Claims19
A centrifugal air-oil separator system for separating oil particles from air in a gas turbine engine system, comprising:
- a rotatable shaft journaled within a housing of the gas turbine engine system, the rotatable shaft including an axially extending bore formed at least partially through the rotatable shaft;
- a gear integral to or mounted on an outer surface of the rotatable shaft and radially extending away from the rotatable shaft, the gear comprises gear teeth and a gear web;
- and
- a breather mounted on the rotatable shaft and independent from and in contiguous contact with the gear,
- wherein the rotatable shaft has a plurality of angularly spaced passageways extending radially outward through the rotatable shaft from the axially extending bore, wherein the breather includes a plurality of radial holes respectively aligned for fluid communication with the plurality of angularly spaced passageways in the rotatable shaft,
- wherein the breather comprises a first part and a second part, wherein the first part and the second part are mounted on the rotatable shaft and in contiguous contact with the gear.
