Abstract
Provided is a drive train of a wind turbine. The drive train includes a torque limiter assembly including a torque limiter. The torque limiter includes: a first clamping disk, a friction disk, a second clamping disk, and a preloading means. The clamping disks and the friction disk are configured such that the clamping disks frictionally transmit a torque to the friction disk. The torque limiter assembly further includes a torque shaft and a hub shaft. The torque shaft is connected to a rotor of the wind turbine, and the hub shaft is connected to a generator rotor of a generator. The friction disk is bolted to the hub shaft via interface bolts from a downwind side, such that the torque limiter is detachable from the hub shaft as a whole. Further provided is a wind turbine.

A drive train of a wind turbine comprising a torque limiter assembly, the torque limiter assembly comprising:
- a torque shaft connected to a rotor of the wind turbine;
- a hub shaft connected to a generator rotor of a generator of the wind turbine;
- a torque limiter comprising a first clamping disk, a friction disk, a second clamping disk, and a preloading means,
- wherein the first clamping disk, the second clamping disk, and the friction disk are configured such that the friction disk is frictionally clamped between the first clamping disk and the second clamping disk,
- wherein a clamping force to frictionally clamp the friction disk between the first clamping disk and the second clamping disk is pre-determined by the preloading means such that the first clamping disk and the second clamping disk frictionally transmit a torque up to a predefined maximum torque to the friction disk, and an over-torque above the predefined maximum torque causes the friction disk to slip relative to the first clamping disk and the second clamping disk,
- wherein the friction disk is bolted to the hub shaft via interface bolts from a downwind side, such that the torque limiter is detachable from the hub shaft as a whole;
- wherein the torque shaft comprises a seal ring in a downwind flange portion of the torque shaft, wherein the seal ring is configured and arranged to provide a sealing between the torque shaft and the friction disk, or to provide a sealing between the torque shaft and the hub shaft.
A drive train of a wind turbine comprising a torque limiter assembly, the torque limiter assembly comprising:
- a torque shaft connected to a rotor of the wind turbine;
- a hub shaft connected to a generator rotor of a generator of the wind turbine;
- a torque limiter comprising a first clamping disk, a friction disk, a second clamping disk, and a preloading means,
- wherein the first clamping disk, the second clamping disk, and the friction disk are configured such that the friction disk is frictionally clamped between the first clamping disk and the second clamping disk,
- wherein a clamping force to frictionally clamp the friction disk between the first clamping disk and the second clamping disk is pre-determined by the preloading means such that the first clamping disk and the second clamping disk frictionally transmit a torque up to a predefined maximum torque to the friction disk, and an over-torque above the predefined maximum torque causes the friction disk to slip relative to the first clamping disk and the second clamping disk,
- wherein the friction disk is bolted to the hub shaft via interface bolts from a downwind side, such that the torque limiter is detachable from the hub shaft as a whole;
- wherein the torque shaft is connected to the first clamping disk via an intermediate disk comprised by the torque limiter, and wherein the intermediate disk comprises through holes providing access to the interface bolts, wherein the intermediate disk is bolted to the torque shaft and to the first clamping disk.
