<p>PURPOSE:To obtain a speed ring sufficiently bearable for flexural rigidity with a small welding quantity by welding only the part of which rigidity is elevated by fixedly securing ring-like main plates with stay vanes, except the other part, at welding reinforcing rings with flanges. CONSTITUTION:In a speed ring 1, a plurality of stay vanes 3 spaced in the circumferential direction are fixedly secured between ring-like main plates 2 arranged opposedly and in parallel. Further, a ring-like reinforcing ring 5 is arranged on the outside of the ring-like main plate 2, and a ring-like flange 6 is arranged on its outside. In this case, the connecting parts A between the ring-like main plate 2 and the reinforcing ring 5 and between the reinforcing ring 5 and the flange 6, where are corresponding to the elevated rigidity part by fixedly securing the ring-like main plate 2 with the stay vane 3, are respectively welded, and the other mutually connected parts B are not welded.</p> |
