Abstract

A device for applying abradable material to a surface of an annular casing of a turbine engine, wherein the casing extends along a longitudinal axis, comprises a support equipped with first guiding means capable of guiding the support in relation to the casing in a radial direction in relation to the axis of the casing. The support is equipped with second guiding means capable of guiding the support in relation to the casing in an axial direction. The device further includes an application roller pivotally mounted in relation to the support in the axial direction and adjustment means allowing adjustment of the position of the roller in relation to the first guiding means, in the radial direction.

First claim

The invention claimed is:

1. A device for applying abradable material, designed to apply abradable material to a surface of an annular casing of a turbine engine, wherein the casing extends along a longitudinal axis and the device comprises a support equipped with first guiding means capable of guiding the support in relation to the casing in a radial direction in relation to the axis of the casing, the support being equipped with second guiding means capable of guiding the support in relation to the casing in an axial direction of the casing, an application roller being pivotally mounted in relation to the support in the axial direction and adjustment means allowing adjustment of the position of the roller in relation to the first guiding means, in the radial direction, wherein the device is configured to be mounted on the casing and move relative to a fixed location of the casing during application of the abradable material.

2. The device according to claim 1 , wherein the first guiding means comprises rolling means capable of bearing on the casing in the radial direction and capable of moving on said casing.

3. The device according to claim 1 , wherein the second guiding means comprises rolling means capable of bearing on the casing in the axial direction and capable of moving on said casing.

4. The device according to claim 1 , wherein the support comprises a first part and a second part movable in the radial direction in relation to the first part, with the roller being pivotally mounted on the second part of the support and the first guiding means and the second guiding means being mounted on the first part of the support.

5. The device according to claim 4 , wherein the adjustment means can be mounted between the first part and the second part of the support and are designed to adjust the position of the second part in relation to the first part, in the radial direction.

6. The device according to claim 5 , wherein the adjustment means comprise at least one screw interacting with at least one nut, with pivoting of the screw in relation to the nut causing translational movement of the second part in relation to the first part.

7. The device according to claim 5 , further comprising translational guiding means for guiding the second part in relation to the first part, in the radial direction.

8. The device according to claim 1 , wherein the support comprises gripping means.

9. The device according to claim 1 , wherein the roller comprises at least two parts capable of pivoting independently of each other.

10. The device of claim 8 , wherein the gripping means comprises a handle.

11. The device according to claim 9 , wherein the at least two parts capable of pivoting independently of each other comprise at least one cylindrical part and at least one frustoconical part.
