SCROLL MEMBER, METHOD OF PRODUCING THE SCROLL MEMBER, COMPRESSION MECHANISM, AND SCROLL COMPRESSOR |
摘要 |
<p>An object of this invention is to reduce wear and deformation in a scroll member. A method for manufacturing an orbiting scroll includes a step (a) and a step (b). In step (a), cast iron is formed and an iron casting (261) is obtained. In step (b), the iron casting (261) obtained in step (a) is cut and an orbiting scroll is obtained. The iron casting (261) obtained in step (a) has a fixing part (261a) and a spiraling part (261b). The spiraling part (261b) is fixed to the fixing part (261a), and extends in a spiraling formation around a center (9). A dimension of a specified portion of the spiraling part (261b) is greater than the dimension of the same portion after step (b) is performed. Specifically, in a portion (2612) of an end (2611) at the center (9) of the spiral, a thickness (d1) is greater than a thickness (h1) of the portion (2612) after step (b) is performed.</p> |
