Abstract

A method for assembling an annular seal element, formed by a sealing cord which runs around an opening on a seal receptacle which runs around on the outside of a component. The method includes introducing two assembly fingers into the opening of the annular seal element, stretching the annular seal element by moving the assembly fingers apart from one another, with the formation of a cord portion of the sealing cord, the cord portion being freely tensioned between the assembly fingers, placing the freely tensioned cord portion onto the seal receptacle in a contact region, applying the annular seal element, by way of its opening, onto the seal receptacle, and removing the assembly fingers from the annular seal element. The assembly fingers are moved so as to follow the profile of the seal receptacle, to travel around the seal receptacle in opposite directions.

First claim

What is claimed is:

1. A method for assembling an annular seal element, which is formed by a sealing cord which runs around an opening, on a seal receptacle which runs around on the outside of a component, comprising:
introducing two assembly fingers into the opening of the annular seal element,
stretching the annular seal element by moving the assembly fingers apart from one another, with the formation of a cord portion of the sealing cord, said cord portion being freely tensioned between the assembly fingers,
placing the freely tensioned cord portion onto the seal receptacle in a contact region,
applying the annular seal element, by way of its opening, onto the seal receptacle, and
removing the assembly fingers from the annular seal element,
wherein, for the application of the annular seal element, the assembly fingers are moved so as to follow the profile of the seal receptacle, so as to travel around the seal receptacle in opposite directions.

2. The method of claim 1 wherein during the traveling-around operation, the assembly fingers are moved at a substantially constant spacing from the seal receptacle.

3. The method of claim 1 wherein the assembly fingers are attached to robot manipulators which are configured to be movable independently of one another, along multiple axes.

4. The method of claim 1 wherein at least one assembly finger has a retaining device in which the sealing cord is positioned during the stretching and traveling-around operations.

5. The method of claim 1 wherein, for removal, the assembly fingers are tilted relative to the seal receptacle and the annular seal element.

6. The method of claim 1 wherein the seal receptacle is formed by a groove which runs around on the outside.

7. The method of claim 1 wherein, during the stretching operation, the annular seal element extends substantially parallel to a stretching plane.

8. The method of claim 7 wherein, during the traveling-around operation, the stretching plane is tilted toward the receiving plane.

9. The method of claim 1 wherein the seal receptacle extends substantially parallel to a receiving plane.

10. The method of claim 1 wherein, before the placing-on of the freely tensioned cord portion, the stretching plane is inclined relative to the receiving plane.
