The figures show one embodiment of this invention, in which Fig. 4 is a longitudinal sectional view, Fig. 5 is a sectional view taken along the line ■-■ in Fig. 4', and Fig. 6 is a sectional view taken along the line
The figure is an enlarged view of the part ■ in Fig. 5, and Fig. 7 is an enlarged view showing the mutual relationship between the middle frame plate, the band-type tightening device, the inner ring, and the core bolt, where A is a front view and B is a side view. In the figure, 1 is a stator frame, 2 is a middle frame plate, 3 is a core bolt, 4 is a stator core, 9 is a band-type tightening device, and 8 is an inner ring. Note that the same reference numerals indicate the same or corresponding parts.

Claims

[Claims for Utility Model Registration] 1. A plurality of core bolts that are provided at predetermined positions on the outer periphery of the stator core and tighten and fix the stator core in the axial direction, and a plurality of core bolts that are provided around the stator core through these core bolts. What is claimed is: 1. A stator core support device for a rotating electrical machine, comprising a tightening device that tightens the stator core in the stator frame and is attached to the stator frame to hold the stator core within the stator frame. 2. The stator core support device for a rotating electric machine as set forth in claim 1, wherein the tightening device is a band-type tightening device divided into two. 3. A stator core support device for a rotating electric machine according to claim 1 or 2, wherein the tightening device is partially welded to the stator frame. A band-type tightening device divided into 42 parts consists of a seat plate provided at both ends of each divided piece, and a bolt device that straddles between the seat plates of the two divided pieces and tightens both. A stator core support device for a rotating electric machine according to claim 2 of the patent registration claim.゛
