Filed:

Sep 12, 1990

Appl. No.:

7/580990

Inventors:

Spencer H. Shepard - Charlotte NC

Albert J. Partington - Winter Springs FL

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

F01D 532

US Classification:

2988921

Abstract:

Machine parts are connected together to form an assembly by means of pins which form an interference fit with passages in the parts and whose ends are flush with two opposed surfaces of the assembly. Each pin is provided with an annular groove spaced from one end of the pin by a distance equal to the distance between the opposed surfaces. A positioning member is seated in the groove and the pin is inserted into an associated passage so that the positioning member bears against one opposed surface. After a tight fit is achieved, the protruding portion of the pin is broken away. A device is provided for testing the tightness of an inserted pin. The device may engage the annular groove and apply a tensile test force. Alternatively, after the end of the pin has been broken away, the device may bear against the end of the remaining pin portion and apply a compressive test force.

International Classification:

B21K 304

US Classification:

291568R

Abstract:

A method is provided for forming a circular array of rotatable blades from blades having an integral shroud with a leading planar surface and a trailing planar surface, the leading planar surface being generally parallel to an axial radial plane passing through the center of the root of the blade and the trailing surface, if extended, intersecting the axial radial plane passing through the center of the root of the blade to form an angle generally equal in degrees to 360 divided by the number of blades forming the circular array. Strict radial alignment is provided by assembling the complete blade row such that all blade center lines coincide with the groove center lines, with the shroud mating surfaces in complete contact and in tangential compression.
