A clamping arrangement for the force-fit connection of an outer component to an inner component including an inner conical ring and an outer conical ring wherein one of the rings has leadthrough bores clamping screws and the other ring has threaded bores for the clamping screws to brace the rings against one another via the conical peripheral surfaces, and against the inner and outer component arrangement. At least one leadthrough bore having an ejector thread for an ejector screw and the diameter of the ejector thread being greater than the diameter of the clamping screw. The arrangement including an ejector ring with an ejector bore for the leadthrough of the ejector screw which can be screwed into the ejector thread and an ejector surface for engaging a clamping screw head that is incompletely screwed into the corresponding threaded bore for the transmission of an ejector force onto the clamping screw.

The present invention relates to a coupling assembly (1) for fixedly connecting a rotational member (2) to an end section (3) of a hollow shaft (4). It may e.g. be used for connecting the main shaft (4) of a wind turbine (28) to a planet carrier (2) of a coaxial planetary gear system. The coupling assembly (1) comprises a shrink ring (6) and a coupling element (7). The shrink ring (6) has an outer diameter corresponding to the inner shaft diameter (d) and a conical surface (14) for connecting the shrink ring (6) and the coupling element (7). The coupling element (7) comprises an annular groove (18) with a groove diameter corresponding to the outer shaft diameter (D) and a conical surface (20) matching the shrink ring (6). When in use, the hollow shaft (4) is arranged in the groove (18) and connected to the coupling element (7) by axially extending bolts (9). Hereby a torque can be transferred by both the shrink connection and the bolts fastened into the hollow shaft. The coupling element (7) preferably comprises an outer flange (26) to which the rotational member (2) can be fastened.

The invention relates to a connecting arrangement for connecting a shaft to a component. A tapered outer surface of an inner ring and a tapered inner surface of an outer ring are configured in a manner corresponding to each other. The outer ring surrounds the inner ring. A union nut surrounds the outer ring and the threaded piece. The union nut has an internal thread and the threaded piece has an external thread, wherein the internal and the external threads are configured in a manner corresponding to each other.
