Abstract

Official abstract text for this publication.

A yaw drive for a wind turbine includes a motor, a gear assembly connected to the motor, and a torque limiter. The torque limiter is arranged between the motor and the gear assembly and is capable of transferring torque between the motor and the gear assembly, and capable of limiting torque transfer between the motor and the gear assembly when the torque applied to the torque limiter exceeds a threshold value. A torque transferring part of the torque limiter includes a first set of discs connected to the motor and a second set of discs connected to the gear assembly, the discs of the first set being arranged interleaved with the discs of the second set, thereby forming a stack of discs. A friction between the discs provides torque transfer between the discs. The discs rotate relative to each other when an applied torque overcomes the friction between the discs.

First claim

Opening claim text (preview).

The invention claimed is: 1. A yaw drive for a yawing system for a wind turbine, the yaw drive comprising: a motor, a gear assembly operationally connected to the motor, and a torque limiter arranged detachably between the motor and the gear assembly, in such a manner that the torque limiter is capable of transferring torque between the motor and the gear assembly, and the torque limiter being capable of limiting torque transfer between the motor and the gear assembly when the…
