An assembly of a bladed wheel and a shaft of a turbomachine wherein said bladed wheel is detachably attached to the shaft, said assembly comprising:
- a bladed wheel;
- a turbomachine having a shaft;
- a mechanism for a detachable attachment of the wheel to the shaft, the mechanism comprising:
- (i) a sleeve-like extension extending from the bladed wheel towards the shaft;
- (ii) a fastening unit which is at least substantially arranged in the sleeve-like extension, said sleeve-like extension being encompassed by a thicker-walled bushing of a correspondingly cylindrical recess of the shaft;
- (iii) a clamping bushing encompassed by said sleeve-like extension;
- and
- (iv) a screw element that connects the shaft to the bladed wheel and is located axis-parallel to the bladed wheel and shaft wherein the screw element is a locking screw which interacts with the fastening unit.
A detachable attachment of a bladed wheel to a shaft of a turbomachine having a screw element connecting the wheel and the shaft and extending along a horizontal axis of the shaft comprising:
- a sleeve-like extension extending from the bladed wheel towards the shaft;
- a fastening unit which is at least substantially arranged in the sleeve-like extension, said sleeve-like extension being encompassed by a thicker-walled bushing of a correspondingly cylindrical recess of the shaft;
- a clamping bushing encompassed by said sleeve-like extension;
- and wherein the screw element is a locking screw which interacts with the fastening unit.
