Scroll compressor with shaft inserting portion and manufacturing method thereof |
摘要 |
A scroll compressor having a rotational shaft insertion hole and a fabrication method thereof are provided. The scroll compressor includes a casing; a fixed scroll fixed to an inner wall surface of the casing; an orbiting scroll combined with the fixed scroll to form a compression chamber while performing an orbiting movement with respect to the fixed scroll; a rotational shaft having a shaft portion inserted into the fixed scroll, an eccentric portion that penetrates the fixed scroll to be combined with the orbiting scroll, and a neck portion having a diameter less than a diameter of the eccentric portion to connect the eccentric portion to the shaft portion, wherein the shaft portion, the eccentric portion, and the neck portion are integrally formed; a fixed bush interposed between the fixed scroll and the shaft portion; and a driving unit configured to drive the rotational shaft. A neck portion insertion hole, into which the neck portion is inserted, and a shaft portion insertion hole, into which the shaft portion is movably inserted in a transverse direction, are formed at the fixed scroll, and the fixed bush restricts a transverse directional movement of the shaft portion to maintain a state in which an outer circumferential portion of the neck portion insertion hole is inserted into the neck portion. |

1. A scroll compressor, comprising:
a casing; a fixed scroll fixed to an inner wall surface of the casing; an orbiting scroll combined with the fixed scroll to form a compression chamber while performing an orbiting movement with respect to the fixed scroll; a rotational shaft comprising a shaft portion inserted into the fixed scroll, an eccentric portion that penetrates the fixed scroll to be combined with the orbiting scroll, and a neck portion having a diameter less than a diameter of the eccentric portion, that connects the eccentric portion to the shaft portion, wherein the shaft portion, the eccentric portion, and the neck portion are integrally formed; a fixed bush interposed between the fixed scroll and the shaft portion; and a driving unit configured to drive the rotational shaft, wherein a neck portion insertion hole, into which the neck portion is inserted, and a shaft portion insertion hole, into which the shaft portion is movably inserted in a transverse direction, are formed at the fixed scroll, and wherein the fixed bush restricts a transverse directional movement of the shaft portion to maintain a state in which an outer circumferential portion of the neck portion insertion hole is inserted into the neck portion. |
