The outer annular member is configured to slidingly engage the conduit at the aperture in the outer annular member.
Claims17
A turbine arrangement comprising a turbine rotatably mounted on a bearing hub, wherein the bearing hub comprises an outer annular member surrounding a bearing chamber, the outer annular member defining an aperture to receive a conduit which can extend to the bearing chamber, wherein the outer annular member is configured to slidingly engage the conduit at the aperture.
A bearing hub for a gas turbine engine comprising an outer annular member surrounding a bearing chamber, the outer annular member defining an aperture to receive a conduit which can extend to the bearing chamber, wherein the outer annular member is configured to slidingly engage the conduit at the aperture and wherein the outer annular member includes sealing means at said aperture, whereby the sealing means can engage the conduit to provide sealing between the outer annular member and the conduit and further comprising holding means on the outer annular member, surrounding the aperture, to hold the sealing means.
A bearing hub for a gas turbine engine comprising an outer annular member surrounding a bearing chamber, the outer annular member defining an aperture to receive a conduit which can extend to the bearing chamber, wherein the outer annular member is configured to slidingly engage the conduit at the aperture and wherein the outer annular member includes sealing means at said aperture, whereby the sealing means can engage the conduit to provide sealing between the outer annular member and the conduit and wherein the sealing means comprises a sealing ring.
A bearing hub for a gas turbine engine comprising an outer annular member surrounding a bearing chamber, the outer annular member defining an aperture to receive a conduit which can extend to the bearing chamber, wherein the outer annular member is configured to slidingly engage the conduit at the aperture and further comprising an inner annular member defining the bearing chamber, the outer annular member extending around the inner annular member, wherein the inner annular member defines a further aperture to allow communication between the conduit and the bearing chamber.
