  • System and method for securing a radially inserted integral closure bucket to a turbine rotor wheel assembly having axially inserted buckets
    Patent number: 6416286
    Abstract: 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.

  • Method of reducing burr formation during turbine bucket cover machining
    Patent number: 6363612
    Abstract: A method of reducing the formation of burrs during machining of turbine bucket covers of a turbine assembly includes the steps of inserting a filler material in a gap formed between adjacent bucket covers of a turbine assembly, machining the bucket covers to produce a desired profile for the bucket covers, and removing the filler material.
