A disk for a machine rotor includes a disk body having an outer periphery formed with a plurality of axially-oriented slots; a plurality of buckets, each bucket having an airfoil portion and an attachment portion, the attachment portion loaded axially into a respective one of the plurality of axially-oriented slots. A plurality of arcuate seal plate segments arranged about the outer periphery of the disk body, each covering at least two of the plurality of axially-oriented slots and respective attachment portions of the plurality of buckets. A retention pin extends axially through each of the plurality of arcuate seal plate segments and into an axially oriented bore in the disk body. The retention pin has an inner end engageable with a locking key and adapted to move the locking key into a locking position which prevents axial movement of a pair of adjacent ones of the plurality of buckets.

1. A disk for a machine rotor comprising: a disk body having an outer periphery formed with a plurality of axially-oriented slots; a plurality of buckets, each bucket having an airfoil portion and an attachment portion, said attachment portion loaded axially into a respective one of said plurality of axially-oriented slots; a plurality of arcuate seal plate segments arranged about said outer periphery of said disk body, one of said plurality of arcuate seal plate segments covering at least two of said plurality of axially-oriented slots and respective attachment portions of said plurality of buckets; and a retention pin extending axially through said one of said plurality of arcuate seal plate segments and into a respective axially oriented bore in said disk body; said retention pin having an inner end engageable with a locking key and adapted to move said locking key into a locking position which prevents axial movement of a pair of adjacent ones of said plurality of buckets. 2. The disk of claim 1 wherein said axially oriented bore in said disk body intersects a radial slot in said disk body, said locking key located in said radial slot and movable radially outwardly into cut-outs formed, respectively, in said pair of adjacent ones of said plurality buckets. 3. The disk of claim 2 wherein said retention pin is provided with first and second tabs on respective inner and outer ends thereof, said tabs extending in diametrically opposed directions. 4. The disk of claim 3 wherein said axially oriented bore is formed with a groove along a radially inward side thereof, said groove sized and shaped to accommodate said first tab on said retention pin as said retention pin is moved through said axially oriented bore, said radial slot located to permit said retention pin to be rotated so that said first tab moves into engagement with said locking key and moves said locking key radially outwardly into said locking position. 5. The disk of claim 4 wherein said second tab is engageable with an outer surface of said one of said plurality of arcuate seal plate segments to hold said one arcuate seal plate segment in place against said disk body. 6. The disk of claim 1 wherein said retention pin is formed with a tool engagement slot across an end face at an outer end thereof. 7. The disk of claim 3 wherein said locking key has four sides, a radially outer surface and a radially inner surface, said radially inner surface formed with a groove adapted to receive said first tab. 8. The disk of claim 5 wherein said second tab engages a shoulder formed in said one of said plurality of arcuate seal plate segments when said locking key is in said locking position. 9. The disk of claim 1 wherein said one of said plurality of arcuate seal plate segments is formed with a hook portion at the radially outer end, radially supported on a lip formed on said disk body. 10. The disk of claim 9 wherein a seal element is interposed between said disk body and said one of said plurality of arcuate seal plate segments at said radially outer end thereof. 11. The disk of claim 1 wherein said one of said plurality of arcuate seal plate segments is formed with an offset radially inner edge seated in a recess formed in said disk body. 12. The disk of claim 1 wherein said one of said plurality of arcuate seal plate segments includes an axially projecting flange at its radially inner end adapted to interface an adjacent spacer. 13. A disk for a machine rotor comprising: a disk body having an outer periphery formed with a plurality of axially-oriented slots; a plurality of buckets, each bucket having an airfoil portion and an attachment portion, said attachment portion loaded axially into a respective one of said plurality of axially-oriented slots; and a plurality of arcuate seal plate segments arranged about said outer periphery of said disk body, one of said plurality of arcuate seal plate segments covering at least two of said plurality of axially oriented slots and respective attachment portions of said plurality of buckets; and at least one retention pin extending axially through said one of said plurality of arcuate seal plate segments and into an axially oriented bore in said disk body; said at least one retention pin having an inner end engageable with a locking key and adapted to move said locking key into a locking position which prevents axial movement of a pair of adjacent ones of said plurality of buckets; wherein said axially oriented bore in said disk intersects a radial slot in said disk body, said locking key located in said radial slot and movable radially outwardly into cut-outs formed, respectively, in said pair of adjacent ones of said plurality of buckets; wherein said at least one retention pin is provided with first and second tabs on respective inner and outer ends thereof, said first and second tabs extending in diametrically opposed directions; wherein said axially oriented bore is formed with a groove along a radially inward side thereof, said groove sized and shaped to accommodate said first tab as said retention pin is moved through said axially oriented bore, said radial slot located to permit said at least one retention pin and said first tab to be rotated so that said first tab moves into engagement with said locking key and moves said locking key radially outwardly into said locking position. 14. The disk of claim 13 wherein said second tab is engageable with an outer surface of said one of said plurality of arcuate seal plate segments to hold said one of said plurality of arcuate seal plate segments in place against said disk body when said locking key is in said locking position. 15. The disk of claim 13 wherein said at least one retention pin is formed with a tool engagement slot across an outer end face thereof. 16. The disk of claim 13 wherein said one of said plurality of arcuate seal plate segments is formed with a hook portion at a radially outer end, radially supported on a lip formed on said disk body. 17. The disk of claim 16 wherein a seal element is interposed between said disk body and said one of said plurality of arcuate seal plate segments at said radially outer end. 18. The disk of claim 13 wherein said one of said plurality of arcuate seal plate segments is formed with an axially offset radially inner edge seated in a recess formed in said disk body. 19. The disk of claim 13 wherein a radially inner end of said one of said plurality of arcuate seal plate segment includes a flange adapted to interface an adjacent spacer. 20. A retention pin for securing a bucket and a seal plate segment to a machine rotor disk body comprising: an elongated pin body having an inner end and an outer end, said inner end formed with a first, substantially rectangular tab and said outer end formed with a second, substantially arcuate tab; said first and second tabs extending from said pin body in substantially diametrically-opposed directions.
