Abstract

A corrosion inhibitor container configured to be screwed into a core hole of a gearbox housing via at least one external thread includes at least one chamber for holding a corrosion inhibitor, at least one gas-permeable wall separating the at least one chamber from an interior of the gearbox housing when the corrosion inhibitor container is screwed into the core hole, the at least one external thread, at least one internal thread, and a screw plug configured to be screwed into the internal thread. The screw plug is configured to be screwed into the core hole when the corrosion inhibitor container is not screwed into the core hole.

Claims

1. :

A corrosion inhibitor container being configured to be screwed into a core hole of a gearbox housing via at least one external thread, comprising;

at least one chamber for holding a corrosion inhibitor;

at least one gas-permeable wall separating the at least one chamber from an interior of the gearbox housing when the corrosion inhibitor container is screwed into the core hole;

the at least one external thread;

at least one internal thread; and

a screw plug configured to be screwed into the internal thread,

wherein the screw plug is configured to be screwed into the core hole when the corrosion inhibitor container is not screwed into the core hole.

2. :

The corrosion inhibitor container according to claim 1, wherein the at least one chamber is accessible through the at least one internal thread.

3. :

The corrosion inhibitor container according to claim 1, wherein the corrosion inhibitor container has a rotationally symmetrical basic shape.

4. :

The corrosion inhibitor container according to claim 1, wherein the corrosion inhibitor container consists of a first part, a second part, and a third part, the first part comprising the at least one gas permeable wall, the second part comprising the at least one external thread, and the third part comprising the at least one internal thread, and wherein the second part is arranged between the first part and the third part.

5. :

The corrosion inhibitor container according to claim 4, wherein the second part adjoins the first part and the third part.

6. :

A wind power gearbox, comprising;

a gearbox housing having a corrosion inhibitor container according to claim 1, and a core hole,

wherein the corrosion inhibitor container is configured to be screwed into the core hole.

7. :

The wind power gearbox according to claim 6, wherein a screw plug is screwed into the internal thread of the corrosion inhibitor container.

8. :

A method for assembling a wind turbine, the method comprising;

installing a wind power gearbox according to claim 7;

removing the corrosion inhibitor container from the core hole;

removing the screw plug from the internal thread; and

screwing the screw plug into the core hole.
