０５を傾斜面０７に当てて溶接していた。(A) In the examples shown in Figures 3a to 3d, the outer circumferential portion 06 of the speed ring side plate 02 has a flat circular outer diameter.
Then, a substantially arcuate inclined surface 07 corresponding to the number of divisions of the casing body plate 05 was formed, and the casing body plate 05 was placed against the inclined surface 07 and welded.

の傾斜面０７の成形工数が極めて大きい。Problems to be solved by the invention According to the conventional method, the inner diameter of the casing body plate 05 is joined to the outer peripheral part 07 of the speed ring side plate 02 from the large diameter at the beginning of winding to the small diameter at the end of winding. The thickness of the speed ring side plate 02 must be increased in terms of strength, which increases material and manufacturing costs. Further, although the welding line is a curved line in FIG. 4a, and the welding line is a straight line in FIG. 3a, the number of man-hours required to form the arcuate inclined surface 07 corresponding to the number of divisions of the casing body plate 05 is extremely large.

案した。Means for Solving the Problems The present invention solves the above problems by welding the divided casing body plate to the speed ring side plate by welding the casing body plate only at the outer edge of the speed ring side plate. In order to make the welding line of the outer edge part straight, the outer edge part is made polygonal and has a trapezoidal cross section. I devised a plan.

分割数に対応した多角形とする。Embodiments The present invention will be explained with reference to embodiments shown in the accompanying drawings. In FIG. 1, number 1 of the casing body plate 5
Numbers 1 to 18 are welded to the X portion of the upper and lower surfaces of the circular flat plate of the speed ring side plate 2, and numbers 19 to 23 are welded to the Y portion of the outer peripheral edge surface of the speed ring side plate 2.
In FIG. 2, the shape of the outer circumferential edge surface Y of the speed ring side plate 2 is changed from the conventional circular shape to a polygon corresponding to the number of divisions of the casing body plate 6.
この多角形は、側板一辺一辺を各々溶接して形

結果製作も容易となる。Effect By attaching the casing body plates 5, 11 to 23 to the upper surface of the speed ring side plate 2, the casing body plate can be attached to any part of the speed ring side plate 2 (the upper surface, Can be installed on the edge or bottom surface. In addition, since the chamfered part of the outer edge Y is polygonal, the cut end of the chamfered part is trapezoidal rather than arcuate, making it easier to align the grooves of the casing body plate and the speed ring side plate and to weld them. As a result, manufacturing becomes easy.

両面からコスト低減を計れる。Effects of the invention: Since the mounting positions of the casing body plate 5 and the speed ring side plate 2 can be arbitrarily determined at points where the acting force due to the casing internal pressure is large, the acting force from the casing can be transferred through the speed ring side plate.
It can be transmitted smoothly to the stay vane 1,
Both the casing body plate 5 and the speed ring side plate 2 can be made thinner, and costs can be reduced in terms of both material costs and manufacturing costs.
又面落しする個所の外縁Ｙの形状が従来の弓形

れ、この分野からの工数低減も大きい。 Furthermore, the shape of the outer edge Y of the area where the surface is cut is changed from the conventional arcuate shape to a trapezoid, and the height becomes constant. This face-cutting process and the work of aligning the casing body plate are simplified, and the number of man-hours in this field is also greatly reduced.
