Abstract

A torque support is disclosed for transmitting a supporting force of a gear mechanism of a wind power plant to a carrying mechanism. The torque support has a connection piece, the abutment surfaces of which, which are subjected to the supporting force, are arranged in a manner substantially perpendicular to the supporting force.

First claim

What is claimed is:

1. A torque support configured to support a gear mechanism of a wind power plant and transmit a supporting force to a carrying mechanism of the wind power plant in response to a torque of the gear mechanism, comprising:
a first arm formed integrally with a torque plate and extending in a substantially radial manner with respect to the axis of rotation of the torque, the first arm including a first abutment surface that is substantially planar and is oriented in a first generally horizontal plane;
a first connection piece fixed to the first arm and including a second abutment surface that is substantially planar and abuts against the first abutment surface at the first plane; and
a first damping unit arranged between the first connection piece and the carrying mechanism, the first damping unit being configured to damp torque peaks or supporting force peaks between the first connection piece and the carrying mechanism,
wherein the first connection piece is generally plate shaped and includes a raised portion, which includes the second abutment surface, and two flange portions extending outwardly from the raised portion, the two flange portions including top side surfaces facing in a direction of the first abutment surface and arranged in a second generally horizontal plane that is spaced apart from the first generally horizontal plane,
wherein the first connection piece includes a bottom side surface arranged in a third generally horizontal plane that is spaced apart from the first and second planes, and wherein the first connection piece includes a length in the first pane spanning the raised portion and the two flange portions, a width perpendicular to the length in the first plane spanning the raised portion or either of one of the two flange portions, and a height measured perpendicularly from the first plane to the third plane, the height being less than the length and the width.

2. The torque support according to claim 1 , wherein the torque plate is generally circular and is configured to attach to the gear mechanism of the wind power plant.

3. The torque support according to claim 2 , further comprising a second arm, a second connection piece, and a second damper unit, wherein:
the second arm, the second connection piece, and the second damper unit, respectively, are essentially identical to the first arm, the first connection piece, and the first damper unit, respectively, and the second arm is formed integrally with the torque plate, and
the second arm, the second connection piece, and the second damper unit are arranged symmetrical to the first arm, the first connection piece, and the first damper unit, respectively, about a vertical plane extending centrally through the torque plate.

4. The torque support according to claim 1 , wherein the first connection piece is fixed to the first arm via a force-fitting connection.

5. The torque support according to claim 4 , wherein
the force-fitting connection is a screw connection, which includes a through-hole defined in the arm and a threaded hole defined in the second abutment surface of the first connection piece, and
the through-hole and the threaded hole are formed so as to be aligned with one another and approximately parallel to the supporting force.

6. The torque support according to claim 5 , wherein the torque support includes a multiplicity of screw connections.

7. The torque support according to claim 1 , wherein the first connection piece is fixed directly to an intermediate piece that is connected to the carrying mechanism.

8. The torque support according to claim 7 , wherein the bottom side surface of the first connection piece forms a third abutment surface, the third abutment surface abutting against the intermediate piece in the third plane, and the second plane is arranged between the first and third planes.

9. The torque support according to claim 8 , wherein the intermediate piece includes a fourth abutment surface abutting against the carrying mechanism in a fourth plane that is substantially parallel to the first plane.

10. The torque support according to claim 7 , wherein the intermediate piece includes the first damping unit.

11. The torque support according to claim 1 , wherein the supporting force is directed substantially in an upward vertical direction.

12. A torque support configured to support a gear mechanism of a wind power plant and transmit a supporting force to a carrying mechanism of the wind power plant in response to a torque of the gear mechanism, comprising:
a first arm formed integrally with a torque plate and extending in a substantially radial manner with respect to the axis of rotation of the torque, the first arm including a first abutment surface that is substantially planar and is oriented in a first generally horizontal plane;
a first connection piece fixed to the first arm and including a second abutment surface that is substantially planar and abuts against the first abutment surface at the first plane; and
a first damping unit arranged between the first connection piece and the carrying mechanism, the first damping unit being configured to damp torque peaks or supporting force peaks between the first connection piece and the carrying mechanism, wherein:
the first connection piece is generally plate shaped and includes a raised portion, which includes the second abutment surface, and two flange portions extending outwardly from the raised portion, the two flange portions including top side surfaces facing in a direction of the first abutment surface and arranged in a second generally horizontal plane that is spaced apart from the first generally horizontal plane,
the first connection piece is fixed to the first arm via a force-fitting connection,
the force-fitting connection is a screw connection, which includes a through-hole defined in the arm and a threaded hole defined in the second abutment surface of the first connection piece,
the through-hole and the threaded hole are formed so as to be aligned with one another and approximately parallel to the supporting force, and
the first arm is bifurcated between the through-holes of the screw connections to define a recess extending entirely through the first arm in a direction approximately parallel to the through-hole.

13. The torque support according to claim 12 , wherein: the first connection piece includes a bottom side surface arranged in a third generally horizontal plane that is spaced apart from the first and second planes, and the first connection piece includes a length in the first plane spanning the raised portion and the two flange portions, a width perpendicular to the length in the first plane spanning the raised portion or either of one of the two flange portions, and a height measured perpendicularly from the first plane to the third plane, the height being less than the length and the width.

14. A torque support configured to support a gear mechanism of a wind power plant and transmit a supporting force in response to a torque of the gear mechanism, comprising:
an arm which extends in a substantially radial manner with respect to the axis of rotation of the torque and includes a first abutment surface;
a connection piece fixed to the arm and including a second abutment surface abutting against the first abutment surface of the arm and a third abutment surface opposite the second abutment surface; and
an intermediate piece including (i) a first U-shaped profile defining a first central opening and having a first base portion and limbs extending from the first base portion to abut against the third abutment surface of the connection piece, (
