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.

First claim

The invention claimed is:

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.

9. A corrosion inhibitor container, comprising:
a first external thread configured to be screwed into a core hole of a gearbox housing;
a chamber for holding a corrosion inhibitor;
a gas-permeable wall separating the at least one chamber from an interior of the gearbox housing when the first external thread is screwed into the core hole;
an internal thread; and
a screw plug having a second external thread, the second external thread being configured to be screwed into the internal thread and configured to be screwed into the core hole of the gearbox housing when the first external thread is not screwed into the core hole.

10. The corrosion inhibitor container according to claim 9 , wherein the first external thread has a first pitch, and wherein the internal thread has a pitch equal to that of the first pitch.

11. The corrosion inhibitor container according to claim 10 , wherein the second external thread has a pitch equal to that of the first pitch.

12. The corrosion inhibitor container according to claim 9 , wherein the first external thread and the second external thread have the same diameter, thread angle, and pitch.

13. The corrosion inhibitor container according to claim 12 , wherein the internal thread has a diameter corresponding to that of the first and second external threads.

14. The corrosion inhibitor container according to claim 9 , wherein the gas-permeable wall extends, from the first external thread, in a first direction, the corrosion inhibitor container further comprising a fluted wall that extends, from the first external thread, in a second direction opposite the first direction.

15. The corrosion inhibitor container according to claim 14 , wherein the fluted wall is cylindrical and surrounds the internal thread.

16. The corrosion inhibitor container according to claim 15 , wherein the fluted wall has a fluting radius measured from a base of a flute to an axis of rotation of the corrosion inhibitor container, wherein the screw plug includes a base portion disposed in the second direction from the fluted region, and wherein the base portion of the screw plug has a radius that is greater than the fluting radius.
