Method and apparatus for measuring wedge
First Claim
1. A wedge measuring apparatus applied to a structure having a first member having a surface with a slot in which a wedge is driven, and a second member which opposes the surface of said first member so as to be spaced apart therefrom by a predetermined gap, comprising:
- testing means, inserted in a gap formed between said first member and said second member, for testing a fitting state between said wedge and said slot; and
shifting means for shifting said testing means in said gap.

Abstract
A wedge measuring apparatus comprising a measuring head, capable of being inserted between a stator and a rotor of a revolving electric machine, for testing a coil-urging state of wedges inserted in a slot, and a mechanism for moving the measuring head in the longitudinal direction of the stator and the circumferential direction of the rotor. A test for the coil-urging state is performed to prevent a coil from extending from an opening in the radial direction. In this case, the coil is inserted in a slot having the opening formed in a stator wall surface opposite to the rotor, and the slots are formed along the axial direction of the stator core.

19. A measuring apparatus for testing a slackened state of a "wedge" for holding a coil of a revolving electric machine into a slot, comprising:
-
testing means, inserted in a gap between a rotor and a stator of said revolving electric machine, for testing a physical state of said wedge in said slot; and shifting means for movably holding said testing means and shifting said testing means in said gap in both longitudinal and circumferential directions of said stator. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A wedge measuring apparatus comprising:
-
a measuring head capable of being inserted in a gap between a stator and a rotor of a revolving electric machine, formed along an axial direction of an iron core of said stator, said measuring head being arranged to detect a coil-urging state of a wedge inserted in a slot having an opening in a surface opposite to said rotor so as to prevent radial extension of said coil from said opening; and a shift mechanism for shifting said measuring head in both longitudinal and circumferential directions of said stator.

30. A wedge measuring method applied to a structure having a first member having a surface with a slot in which a wedge is driven, and a second member which opposes the surface of said first member so as to be spaced apart therefrom by a predetermined gap, comprising:
-
inserting testing means for testing a fitting state between said wedge and said slot in a gap formed by said first member and said second member; moving said testing means in said gap; measuring a deflection amount of said wedge by said testing means; and judging on the basis of the deflection amount whether the fitting state between said wedge and said slot is satisfactory. - View Dependent Claims (31, 32, 33, 34, 35, 36)
