ASSEMBLY METHOD FOR INTEGRALLY COVERED AXIALLY INSERTED BUCKET BLADES

A system and method for securing an integral closure bucket to a rotor wheel assembly. The integral closure bucket is inserted in a direction coincident with a radius of the rotor wheel assembly, where the remaining buckets have been previously inserted in a direction parallel to the axis of the tur...

description A system and method for securing an integral closure bucket to a rotor wheel assembly. The integral closure bucket is inserted in a direction coincident with a radius of the rotor wheel assembly, where the remaining buckets have been previously inserted in a direction parallel to the axis of the turbine rotor wheel. The closure bucket has an integral shroud and is connected to a turbine rotor wheel assembly in which the remaining buckets have been previously inserted in an axial direction. The buckets adjacent the closure bucket are spread apart both tangentially and axially to provide sufficient clearance for the radial insertion of the integral closure bucket. To prevent axial movement of the closure bucket and adjacent buckets, twist locks are utilized in channels provided in the bottom of the female dovetails in the rotor wheel.
