SCROLL MEMBER, PROCESS FOR MANUFACTURING THE SAME, COMPRESSION MECHANISM AND SCROLL COMPRESSOR |
摘要 |
<p>An object of the present invention is to reduce wear and deformation in a scroll member. A method for manufacturing an orbiting scroll as a scroll member comprises a step (a) and a step (b). In step (a), cast iron is formed and an iron casting is obtained. For example, the cast iron is formed by semi-molten die casting. In step (b), the iron casting obtained in step (a) is cut and an orbiting scroll is obtained. The iron casting (261) obtained in step (a) has a fixed part (261a) and a spiraling part (261b). In the fixed part (261a), the thickness (d2) of a portion (261a2) near the external periphery is greater than the thickness (d1) of a portion (261a1) near the center (9). The spiraling part (261b) is fixed to the fixed part (261a), and is made to extend in a spiraling formation around the center (9). By performing step (b) on the iron casting (261), a panel is obtained from the fixed part (261a), and a compression member is obtained from the spiraling part (261b).</p> |
