Abstract

An anti-corrosion agent container ( 1 ), such that the anti-corrosion agent container ( 1 ) includes at least first and second chambers ( 2, 3 ). At least one perforated wall ( 5, 15 ) separates at least one of the first and the second chambers ( 2, 3 ) from the surroundings ( 10 ). The anti-corrosion agent container can be used in a wind turbine transmission to prevent corrosion.

First claim

The invention claimed is:

1. An anti-corrosion agent container ( 1 ) for preventing corrosion of a corrodible component,
wherein the anti-corrosion agent container ( 1 ) is divided into first and second chambers ( 2 , 3 ) by a partitioning wall ( 4 );
at least a first perforated wall ( 5 ) separates the first chamber ( 2 ) from surroundings ( 10 ) of the container, and the first perforated wall is remote from the partitioning wall;
at least a second perforated wall ( 15 ) separates the second chamber ( 3 ) from the surroundings ( 10 ) of the container, and the second perforated wall is remote from the partitioning wall; and
the anti-corrosion agent container ( 1 ) is connected to a transmission housing cover ( 26 ) which is detachably connectable to a transmission housing such that when the transmission housing cover is connected to the transmission housing, the anti-corrosion agent container is arranged within an interior of the transmission housing.

2. The anti-corrosion agent container according to claim 1 , wherein a first agent ( 8 ) is located within the first chamber ( 2 ), and the first agent releases gases ( 9 ) for corrosion protection the of the corrodible component, and the first perforated wall is located on a side of the first chamber opposite from the partitioning wall.

3. The anti-corrosion agent container ( 1 ) according to claim 2 , wherein a second agent ( 14 ) is located within the second chamber ( 3 ), and the second agent absorbs moisture from the surroundings, and the second perforated wall is located on a side of the second chamber opposite from the partitioning wall.

4. The anti-corrosion agent container ( 1 ) according to claim 1 , wherein the anti-corrosion agent container ( 1 ) is made of a non-corrosive material.

5. The anti-corrosion agent container according to claim 1 , wherein the first and the second chambers ( 2 , 3 ) have at least one of rounded corners and rounded edges.

6. The anti-corrosion agent container according to claim 1 , wherein the anti-corrosion agent container is supported within a wind turbine transmission.

7. An anti-corrosion agent container ( 1 ) for preventing corrosion of a corrodible component in surroundings of the anti-corrosion agent container ( 1 ),
wherein the anti-corrosion agent container ( 1 ) is divided into separate first and second chambers ( 2 , 3 ) by at least one partitioning wall ( 4 ),
the first and the second chambers ( 2 , 3 ) are connected to one another by the at least one partitioning wall ( 4 ),
at least a first perforated wall ( 5 ) separates an interior of the first chamber ( 2 ) from the corrodible component,
at least a second perforated wall ( 15 ) separates an interior of the second chamber ( 2 ) from the corrodible component,
a first agent ( 8 ) is located within the first chamber ( 2 ), and the first agent releases gases ( 9 ) which provides corrosion protection for the corrodible component,
a second agent ( 14 ) is located within the second chamber ( 3 ), and the second agent absorbs moisture from the surroundings of the anti-corrosion agent container ( 1 ) and the corrodible component, and
the anti-corrosion agent container ( 1 ) is connected to a transmission housing cover ( 26 ) which is detachably connectable to a transmission housing such that when the transmission housing cover is connected to the transmission housing, the anti-corrosion agent container is arranged within an interior of the transmission housing.

8. The anti-corrosion agent container according to claim 7 , wherein the at least one partitioning wall is common to both of the first and the second chambers.

9. The anti-corrosion agent container according to claim 8 , wherein the first perforated wall is located on a side of the first chamber opposite from the at least one separating wall and the second perforated wall is located on a side of the second chamber opposite from the at least one separating wall.

10. The anti-corrosion agent container according to claim 8 , wherein the first and the second chambers are arranged such that the first and the second perforated walls face opposite directions from each other.

11. An anti-corrosion agent container ( 1 ) for preventing corrosion of a gear system of a transmission contained within an interior space of a transmission housing, the gear system connecting an input shaft to an output shaft, the transmission housing having an opening separating the gear system from an external environment, and a cover closes the opening,
wherein the anti-corrosion agent container ( 1 ) is divided into separate first and second chambers ( 2 , 3 ) by at least one partitioning wall ( 4 ),
the first and the second chambers ( 2 , 3 ) are connected to one another by the at least one partitioning wall ( 4 ),
at least a first perforated wall ( 5 ) separates an interior of the first chamber ( 2 ) from the gear system contained within the interior space of the transmission housing,
at least a second perforated wall ( 15 ) separates an interior of the second chamber ( 2 ) from the gear system contained within the interior space of the transmission housing,
a first agent ( 8 ) is located within the first chamber ( 2 ), and the first agent releases gases ( 9 ) which provides corrosion protection for the gear system,
a second agent ( 14 ) is located within the second chamber ( 3 ), and the second agent absorbs moisture from the interior space of the transmission housing, and
the anti-corrosion agent container is connected to the cover which is detachably connectable to the transmission housing such that when the cover is connected to the transmission housing, the anti-corrosion agent container is arranged within the interior space of the transmission housing.

12. The anti-corrosion agent container ( 1 ) according to claim 11 , wherein the at least one partitioning wall is common to both of the first and the second chambers, and the first and the second perforated walls are arranged with respect to each other on axially opposite sides of the anti-corrosion agent container.

13. The anti-corrosion agent container ( 1 ) according to claim 11 , wherein the anti-corrosion agent container is connected to a surface of the cover that faces the interior space of the transmission housing when the cover closes the opening of the transmission housing.
