  • Apparatus for aligning scroll compressor
    Patent number: 6618931
    Abstract: There are provided a fixed-scroll moveable device which is capable of moving a fixed-scroll of a scroll compressor in the directions of an X axis and a Y axis, and an orbiting-scroll revolution compensation device which is capable of revolving an orbiting-scroll in a &thgr; direction by way of a main frame. An optimum angle of the fixed-scroll relative to the orbiting-scroll and an optimum wrap clearance are determined at the same time while orbitally moving the orbiting-scroll. Thereby, alignment of a scroll compression section is performed in a short time with a high precision including positioning of a rotating direction of the fixed-scroll relative to the orbiting-scroll.
