Abstract
The present invention relates to a coupling assembly () for fixedly connecting a rotational member () to an end section () of a hollow shaft (). It may e.g. be used for connecting the main shaft () of a wind turbine () to a planet carrier () of a coaxial planetary gear system. The coupling assembly () comprises a shrink ring () and a coupling element (). The shrink ring () has an outer diameter corresponding to the inner shaft diameter (d) and a conical surface () for connecting the shrink ring () and the coupling element (). The coupling element () comprises an annular groove () with a groove diameter corresponding to the outer shaft diameter (D) and a conical surface () matching the shrink ring (). When in use, the hollow shaft () is arranged in the groove () and connected to the coupling element () by axially extending bolts (). Hereby a torque can be transferred by both the shrink connection and the bolts fastened into the hollow shaft. The coupling element () preferably comprises an outer flange () to which the rotational member () can be fastened.
