Claims

[Scope of utility model registration request]

It is arranged on the outer periphery of the stator core and is divided in the circumferential direction.
A cross section that has a circumferential groove in the circumferential direction that engages with the middle frame plate of the stator frame on its outer circumferential side and is arranged between a plurality of core bolts that fix the stator core in the axial direction on its inner circumferential side. A tall ring having a U-shaped groove, an inner ring disposed on the inner circumferential side of the outer ring and to which the core bolts are welded at an appropriate pitch, and a cross section of the inner circumferential side of the outer ring. A presser foot inserted between the U-shaped groove and the outer circumference of the inner ring to distort the inner ring radially inward between the pitches of the core bolt, and a presser foot installed opposite to the split part of the outer ring. is attached to the pair of flanges, and by tightening the outer ring in the circumferential direction, the inner ring is distorted radially inward via the presser foot, and the inner ring is attached to the stator core. A stator core support device for a rotating electric machine, characterized by comprising a tightening member that generates a restraining force.
