Abstract

Provided is a cable twist allowance system for a wind turbine system. The system includes a sun gear disposed within a tower of wind turbine, a pivot disk connected with the sun gear, a plurality of lever members, each including a plurality of cables and spaced a predetermined distance apart from each other, the plurality of level members being pivotably connected with a surface of the pivot disk and rotatable about the sun gear; and a plurality of compression members, each compression member corresponding to each lever member and adjusting a position of a respective lever member based on a radial force applied to the plurality of cables of the respective lever member.

First claim

What is claimed is:

1. A cable twist allowance system for a wind turbine, comprising:
a sun gear disposed within a tower of wind turbine;
a pivot disk connected with the sun gear;
a plurality of lever members, each including a plurality of cables and spaced a predetermined distance apart from each other, the plurality of lever members being pivotably connected with a surface of the pivot disk and rotatable about the sun gear; and
a plurality of compression members, each corresponding to a lever member and adjusting a position thereof based on a radial force applied to the plurality of cables of the respective lever member.

2. The cable twist allowance system of claim 1 , wherein the sun gear comprises a plurality of gears at a periphery region thereof and the plurality of lever members each comprise a plurality of gears at a region thereof corresponding to and engaging with the plurality of gears of the sun gear.

3. The cable twist allowance system of claim 2 , wherein the each lever member includes a housing section at an opposite end of the end of the lever member comprising the plurality of gears, for housing cables therein.

4. The cable twist allowance system of claim 3 , wherein the housing section is formed by a wire restraint portion configured to restrain the cables within the housing section.

5. The cable twist allowance system of claim 1 , wherein the lever compression member comprises a spring member.

6. The cable twist allowance system of claim 1 , wherein each compression member connects a lever member to an adjacent lever member along the periphery region of the sun gear.

7. The cable twist allowance system of claim 1 , wherein a diameter of the cable twist allowance system is varied dependent upon radial forces applied to the plurality of cables which adjust the position of the respective lever member having the plurality of cables.

8. The cable twist allowance system of claim 1 , wherein the compression members are disposed along a central area surface of the sun gear and are arranged to correspond to and in connection with one or more lever members.

9. The cable twist allowance system of claim 8 , wherein the compression members adjust the position of a respective lever member based on radial forces applied to the plurality of cables within the respective lever member.

10. The cable twist allowance system of claim 9 , wherein the sun gear duplicates the position of the respective lever member for a position of each remaining lever member to correspond to the position of the respective lever member.

11. A method for performing cable twist allowance within a wind turbine system, the method comprising:
receiving cable sets including a plurality of cables within housing sections of lever members attached to a sun gear within a cable twist allowance system housed within a tower of the wind turbine system; and
adjusting a position of a lever member based on a radial force applied to the plurality of cables within a cable set of the lever member.

12. The method of claim 11 , wherein the lever members are pivotably connected with a pivot disk connected to the sun gear, and rotatable about the sun gear.

13. The method of claim 11 , wherein the position of the lever member is adjusted using a compression member attaching the lever member to an adjacent lever member along a surface of the sun gear.

14. The method of claim 11 , wherein adjusting the position of the lever member adjusts a diameter of the cable twist allowance system within the tower.
