く適用されだしている。BACKGROUND OF THE INVENTION In recent years, scroll compressors have been increasingly used as compressors for air conditioners.
以下図面を参照しながら、上述した従来のスクロール型
圧縮機の一例について説明する。An example of the conventional scroll compressor mentioned above will be described below with reference to the drawings.
第６図から第８図は従来のスクロール型圧縮機の構造を

である。6 to 8 show the structure of a conventional scroll compressor. In FIG. 5, fixed scroll 1.
The orbiting scroll 2 and the Oldham ring 3 are supported by the crankshaft 6 via a bearing 2b. It is something.
前記自転防止機構は、第６図、第７図及び第８図に示す

うに構成されている。The rotation prevention mechanism engages the protrusion 3a of the Oldham ring 3 with the groove 2a of the orbiting scroll 2, as shown in FIGS. 6, 7, and 8, so that the protrusion slides in the groove. It is configured.

という問題点、またセラミック分散メッキにおいては、
メッキ膜厚の分布が悪く、ラップ、溝等の壁面、底面。Problems to be Solved by the Invention However, in the above configuration, the protrusion 3a of the Oldham ring 3 and the orbiting scroll 2 have a particularly small contact area.
Because the sliding conditions of the groove 2a of the fixed scroll 1 and the wrap 2c of the orbiting scroll 2, which are in sliding and line contact between the groove 2a of the Oldham ring 3, the protrusion 3b of the frame, and the groove 4a of the frame, wear resistance is improved. sexuality is required. Therefore, if an aluminum alloy is used for the orbiting scroll 2, although the weight is reduced and the input and vibration are reduced compared to iron, the wear resistance and seizure resistance are significantly inferior. The dynamic surfaces were subjected to wear-resistant surface treatments such as electroless nickel plating, ceramic dispersion plating, and ceramic spraying. However, these wear-resistant surface treatments
Electroless nickel plating has the problem of insufficient wear resistance, and ceramic dispersion plating has the problem of insufficient wear resistance.
Poor distribution of plating film thickness, walls and bottom surfaces of laps, grooves, etc.

有していた。The problem is that a uniform film thickness cannot be obtained in the horizontal and vertical directions, so a finishing process using precision machining must be added after the plating process. Ceramic thermal spraying also has a problem in that a finishing process using precision machining is required after treatment because the film thickness distribution is worse than ceramic dispersion plating.

There is no precision machining process, and reliability is satisfied.
