Abstract

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.

First claim

What is claimed is:

1. A tool for pressing a ring seal into a component, the tool comprising:
a base including a first end, a second end and a sidewall which forms an aperture along an axis through the base between the first end and the second end, wherein at least a portion of the sidewall radially tapers as the sidewall extends towards the second end;
a support extending out from the second end and laterally overlapping the aperture; a pusher configured to axially engage the ring seal; and
an actuator mounted to the support, the actuator configured to translate the pusher along the axis and thereby push the ring seal through the aperture and press the ring seal into the component;
wherein the pusher has an oval cross-sectional geometry when viewed in a plane that is perpendicular to the axis, the oval cross-sectional geometry has a first overall width along a first direction within the plane, the oval cross-sectional geometry has a second overall width along a second direction within the plane, the first overall width is different than the overall second 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; and
wherein the oval cross-sectional geometry of the pusher is configured for installing the ring seal having a corresponding oval shape.

2. The tool of claim 1 , wherein the portion of the sidewall extends axially from the first end towards the second end.

3. The tool of claim 1 , wherein the portion of the sidewall is a first portion of the sidewall, and a non-tapered second portion of the sidewall is arranged between the first portion and the second end.

4. The tool of claim 3 , wherein the first portion extends an axial first length, and the second portion extends an axial second length that is less than the first length.

5. The tool of claim 1 , wherein the pusher includes a base portion and an annular notch that extends axially and radially into the base portion, and the pusher is configured to receive the ring seal in the notch.

6. The tool of claim 5 , wherein the notch is at a distal end of the base portion, and the pusher includes a guide portion which projects axially out from the base portion at the distal end.

7. The tool of claim 1 , wherein the pusher is rotationally fixed relative to the support and the base.

8. The tool of claim 1 , wherein the support is mounted to the base with one or more fasteners.

9. The tool of claim 1 , further comprising one or more fasteners for anchoring the base to the component.

10. The tool of claim 1 , wherein
the base is configured to receive the ring seal within the aperture; and
the pusher is configured to translate axially within the aperture and move relative to the base to thereby push the ring seal out of the aperture.

11. The tool of claim 1 , wherein the first direction is perpendicular to the second direction within the plane.

12. The tool of claim 1 , wherein the aperture, the pusher and the actuator are coaxial with one another and the axis.

13. A tool for pressing a ring seal into a component, the tool comprising:
a base including a first end, a second end and a sidewall which forms an aperture along an axis through the base between the first end and the second end, wherein at least a portion of the sidewall radially tapers as the sidewall extends towards the second end;
a support extending out from the second end and laterally overlapping the aperture; a pusher configured to axially engage the ring seal; and
an actuator mounted to the support, the actuator configured to translate the pusher along the axis and thereby push the ring seal through the aperture and press the ring seal into the component;
wherein the actuator includes a threaded shaft that extends along the axis through the support and engages the pusher, and the threaded shaft and the aperture are coaxial with one another and the axis; and
wherein the pusher has an oval cross-sectional geometry with a first overall width and a second overall width different than the first overall width, and the oval cross-sectional geometry of the pusher is configured for installing the ring seal having a corresponding oval shape.

14. The tool of claim 13 , wherein the actuator further includes a handle, and the threaded shaft extends along the axis from the handle, through the support, and engages the pusher.

15. A tool for pressing a ring seal into a component, the tool comprising:
a base including a first end, a second end and a sidewall which forms an aperture along an axis through the base between the first end and the second end, wherein the aperture comprises a central bore extending axially along the axis through the base;
a press configured to push the ring seal axially through the aperture and press the ring seal into the component;
wherein the base is configured to radially compress the ring seal as the press pushes the ring seal axially through the aperture;
wherein the sidewall has an oval cross-sectional geometry when viewed in a plane that is perpendicular to the axis; and
wherein a first direction overall width of the oval cross-sectional geometry in a first direction through the plane is different than a second direction overall width of the oval 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; and
wherein the oval cross-sectional geometry of the sidewall is configured for installing the ring seal having a corresponding oval shape.

16. The tool of claim 15 , wherein the press includes
a pusher configured to axially engage the ring seal; and
an actuator configured to translate the pusher along the axis and thereby push the ring seal through the aperture and press the ring seal into the component.
