Methods and tools for pressing a ring seal into a component
Methods and tools are provided for pressing a ring seal into a component. In one method, a tool is anchored to the component. The tool includes a first aperture which extends along an axis. The first aperture is coaxial with a second aperture in the component. The ring seal is pushed axially through the first aperture towards the component, where the tool radially compresses the ring seal as the ring seal moves axially towards the component. The radially compressed ring seal is pressed into the second aperture using the tool.
1. A method comprising:
anchoring a tool to a component, wherein the tool includes a first aperture which extends along an axis, and the first aperture is coaxial with a second aperture in the component;
pushing a ring seal axially through the first aperture towards the component, wherein the tool radially compresses the ring seal as the ring seal moves axially towards the component; and
pressing the radially compressed ring seal into the second aperture using the tool;
wherein the ring seal has an elongated cross-sectional geometry when viewed in a plane that is perpendicular to the axis, the elongated cross-sectional geometry has a first overall width along a first direction within the plane, the elongated cross-sectional geometry has a second overall width along a second direction within the plane, the first overall width is different than the second overall width, the first direction is different from the second direction, and the first direction and the second direction are coincident with the axis within the plane.
2. The method of claim 1 , wherein the tool comprises a pusher which presses the radially compressed ring seal into the second aperture, and the pusher includes a guide portion which projects into the component to guide movement of the pusher.
3. The method of claim 1 , wherein the tool comprises a pusher which presses the radially compressed ring seal into the second aperture, and the pusher axially contacts the component to axially locate the ring seal within the second aperture.
4. The method of claim 1 , wherein the component is a component of a gas turbine engine.
5. The method of claim 1 , wherein the ring seal comprises a radial pinch seal.
6. The method of claim 1 , wherein the elongated cross-sectional geometry is an oval cross-sectional geometry.
7. The method of claim 2 , wherein the pusher axially contacts the component to axially locate the ring seal within the second aperture.
8. A method comprising:
anchoring a tool to a component, wherein the tool includes a first aperture extending along an axis, and the first aperture is coaxial with a second aperture in the component;
pushing a ring seal axially along the axis through the first aperture towards the component, wherein the tool radially compresses the ring seal as the ring seal moves axially along the axis towards the component; and
pressing the radially compressed ring seal into the second aperture using the tool;
wherein the ring seal has an elongated cross-sectional geometry when viewed in a plane perpendicular to the axis, a first direction width of the elongated cross-sectional geometry in a first direction through the plane is different than a second direction width of the elongated cross-sectional geometry in a second direction through the plane, the first direction is perpendicular to the second direction, and the first direction and the second direction are each coincident with the axis.
9. The method of claim 8 , wherein the tool comprises a pusher which presses the radially compressed ring seal into the second aperture, and the pusher includes a guide portion which projects into the component to guide movement of the pusher.
10. The method of claim 9 , wherein the pusher axially contacts the component to axially locate the ring seal within the second aperture.
11. The method of claim 8 , wherein the tool comprises a pusher which presses the radially compressed ring seal into the second aperture, and the pusher axially contacts the component to axially locate the ring seal within the second aperture.
12. The method of claim 8 , wherein the component is a component of a gas turbine engine.
13. The method of claim 8 , wherein the ring seal comprises a radial pinch seal.
14. The method of claim 8 , wherein the elongated cross-sectional geometry is an oval cross-sectional geometry.
