    摘要: A gas turbine engine includes a cover, a support, and a sealing member. The cover has a cover housing and a cover arm extending from the cover housing between a first arm end connected to the cover housing and a second arm end having a cover end surface. The support has a support body, a first support arm extending between a first support arm first end connected to the support body and a first support arm second end. The cover arm extends into the first support arm. The sealing member at least partially extends across a gap defined between the cover end surface and the first support arm.

    摘要: A cylindrical roller bearing installation tool is provided. The cylindrical roller bearing has a plurality of rollers. The installation tool includes a ring-shaped body and a plurality of alignment projections. The ring-shaped body has a circumference and an inner bore. The plurality of alignment projections extend substantially axially outwardly from the body, and are distributed around the circumference of the ring-shaped body. Each alignment projection has at least one roller engagement surface. Each of the alignment projections is uniformly spaced around the circumference of the ring-shaped body.

    摘要: An annular seal plate for a shaft assembly in which the seal plate is disposed between and abuts a first adjacent element that rotates with the shaft and seal plate and a second adjacent element that does not rotate with the shaft. The annular seal plate includes an axial scoop defining an annular lubricant collection area disposed radially outwardly from an oil supply orifice that is in fluid communication with a source of pressurized lubricant supplied through the first adjacent element. Lubricant flows through the oil supply orifice and collects in the collection area. An oil passage places the collection area in fluid communication with a lateral surface facing and abutting the second adjacent element to provide lubricant to the interface between the annular seal plate and the second adjacent element.

    摘要: A contacting seal for a gas turbine engine include a seal element rotationally fixed relative to an axis of rotation, and a seal seat configured to rotate circumferentially about an axis of rotation and contact the seal element at an interface surface of the seal seat. The seal seat includes an interface component including a seat wall including the interface surface and a seat cavity surface opposite the interface surface, such that a wall thickness of the interface component is defined therebetween. A cover component is secured to the interface component, the cover component including a cover cavity surface. The seat cavity surface and the cover cavity surface define a cooling cavity therebetween configured such that a flow of fluid therethrough cools the interface component via contact between the coolant and the seat cavity surface.

    摘要: A seal seat includes an annular body and an extension. The annular body is disposed about a centerline axis. The extension is connected to and extends radially outward from the annular body. The extension includes first, second, and third portions. The first portion is connected to the annular body and is defined by axially opposed upstream and downstream wall faces. The first portion includes a fin connected to the upstream wall face. The second portion is connected to the first portion and extends substantially parallel to the annular body. The third portion is connected to the second portion and extends substantially parallel to the second portion.

    摘要: A spanner nut for a bearing compartment of an engine with a bearing stack on a first shaft that rotates about an engine centerline includes a body, a piloting hook connected to the body, a first threaded portion, and a channel formed by the piloting hook. The piloting hook includes first and second extensions. The first extension is connected to and extends radially inward from the body. The second extension is connected to and extends in an axial direction from the first extension. The second extension includes a radially outward facing surface. The first threaded portion is configured to engage with a second threaded portion on the end of the first shaft. The channel is configured to receive the end of the first shaft. The piloting hook is configured to draw the second extension radially outward as the spanner nut is compressed.
