Abstract
A transmission for a wind turbine includes a first torque bracket and a second torque bracket. The first torque bracket and the second torque bracket are asymmetrical to each other. The torque brackets may include a support arm and a fastening member. The fastening member can be fixed to a machine carrier.
Claims10
A transmission for a wind turbine, comprising:
- a housing forming a first torque bracket and a second torque bracket,
- wherein the first torque bracket and the second torque bracket are asymmetrical in shape, stiffness distribution, and mass distribution relative to each other;
- an input shaft;
- and
- a vibration control weight fixed to a support arm of the first torque bracket,
- wherein the second torque bracket does not have a vibration control weight fixed to it,
- wherein the vibration control weight is configured to mitigate vibration of the first torque bracket induced by rotation of the input shaft,
- wherein the input shaft is configured to rotate about an axis of rotation,
- wherein the first torque bracket and the second torque bracket are integrally connected to the transmission housing,
- wherein the transmission housing surrounds the input shaft about the axis of rotation, and
- wherein the first torque bracket and the second torque bracket each include a fastening eye, the fastening eye of the first torque bracket being arranged at an end of the first torque bracket opposite the axis of rotation and the fastening eye of the second torque bracket being arranged at an end of the second torque bracket opposite the axis of rotation.
