Locking Sub-Assembly for Closing The Remaining Gap Between The First and The Last blade of a Blade Ring Which Are Inserted in a Circumferential Groove of a Turbomachine, and Corresponding Turbomachine

摘要

The invention relates to a closing assembly for closing the gap remaining between the first and the last blade of a blade ring that is inserted in a peripheral groove of a turbo machinery, said assembly consisting of at least two lateral parts, at least one of which can be hooked onto a projection that forms an undercut in said peripheral groove and at least one securing element, which secures the parts from coming detached from the peripheral groove. To provide a particularly reliable closing assembly, the securing element is configured as a pin, joining the parts of the closing assembly in a non-positive fit.
