して軽量化を図る圧縮機に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a compressor in which vanes, cylinder blocks, rotors, side blocks, etc. are made of plastic or carbon material to reduce weight.
(従来の技術)

の冷媒ガスを圧縮するものである。(Prior art) A compressor closes the front and rear opening surfaces of a cylinder block with a pair of side blocks, urges the vanes to protrude from the outer peripheral surface of the rotor toward the inner surface of the cylinder block, and creates a substantially elliptical cylinder chamber. The refrigerant gas within this compartment is compressed.
近年、軽量化を図るため、鉄系金属からアルミニウム材
等の軽合金を用いて製作するようになって来た。In recent years, in order to reduce weight, light alloys such as aluminum have been used instead of iron-based metals for manufacturing.
例えば(1)実公昭50−33712号公報、(2)特
開昭62−60993号公報かある。For example, there are (1) Japanese Utility Model Publication No. 50-33712 and (2) Japanese Unexamined Patent Publication No. 62-60993.
前記(1)の圧縮機は、ベーンをアルミニウム合金によ

耐焼付性や耐摩耗性を向上させようとするものである。The compressor of (1) above is made lightweight by forming the vanes from an aluminum alloy, and by impregnating the surface with tetrafluoroethylene during anodizing coating treatment,
The purpose is to improve seizure resistance and wear resistance.
そして(2)の圧縮機は、ベーンの摺動面に分散剤であ
るセラミック粉末を含有したNlベースのメッキを施す
ことにより、耐焼付性や耐摩耗性に優れたベーンを構成
したものである。The compressor (2) has vanes with excellent seizure and wear resistance by applying Nl-based plating containing ceramic powder as a dispersant to the sliding surfaces of the vanes. .
更に(3)特開平L−L82592号公報があり、この
圧縮機はシリンダーブロック、両サイドプロ。Furthermore, there is (3) Japanese Patent Application Laid-open No. LL82592, which describes a compressor with a cylinder block and both sides.

図ると共に、ポリ4弗化エチレンを分散したNI無電解
複合メッキを処したものである。The rotor and vanes are made of aluminum to reduce weight, and are coated with NI electroless composite plating in which polytetrafluoroethylene is dispersed.

前記(2)においては、分散材であるセラミックスによ
るメッキ層か、例えばSICの場合にはHv= 300
0〜3500、TICの場合にはHv・2800〜38
00、SI3N4の場合にはHv・2400〜2800
と非常に硬いため、メッキ処理後の研磨加工の加工性が
悪くなり、研削時間かか\ると共に砥石の寿命が非常に
短くなって生産性が低くなる。(Problem to be solved by the invention) However, in this type of compressor, it is possible to reduce the weight by using aluminum-based light metal, and at the same time, it is possible to improve seizure resistance and wear resistance. In (1), the anodic coating is of the same type as the mating material and is insufficient in terms of durability such as sliding properties and seizure resistance. or,
In the above (2), Hv=300 in the case of a plating layer made of ceramics as a dispersion material, or SIC, for example.
0~3500, Hv・2800~38 in case of TIC
00, Hv・2400~2800 in case of SI3N4
Because it is extremely hard, the workability of polishing after plating becomes poor, the grinding time increases, and the life of the whetstone becomes extremely short, resulting in low productivity.
又、鉄メッキを施した技術もあるが、メッキの膜厚寸法
精度が悪く、メッキ処理後に仕上げ加工が必要でコスト
高となり、アルミ材への密着度か熱衝撃の繰返しで低下
し、耐久性上の問題もある。In addition, there is a technology that uses iron plating, but the dimensional accuracy of the plating film thickness is poor, and finishing processing is required after plating, resulting in high costs.The adhesion to the aluminum material deteriorates due to repeated thermal shocks, resulting in poor durability. There is also the above problem.
更に前記(3)においては、耐摩耗性が改善され圧縮機

。Furthermore, in (3) above, although the abrasion resistance has been improved and the performance and durability of the compressor has been improved, it is still not sufficient for the rapidly advancing technology and various problems still remain.
以上のような問題によって圧縮機の摺動部における摩耗
や焼付対策上非常に不都合を感じていた。The above-mentioned problems have been extremely inconvenient in terms of measures against wear and seizure in the sliding parts of the compressor.

A front side block and a rear side block and a front head and a rear head are fixed together, a rotor is rotatably housed in the cylinder block, and a vane is slidably fitted into a vane groove provided in the rotor. In a compressor in which vanes slide as they rotate, and the tip of the vane slides into contact with the inner peripheral surface of the cylinder block, the cylinder block, both side blocks, rotor, and vanes are reinforced by mixing metal powder such as aluminum or copper. It is made of plastic or carbon material, and at least one or more components are plated with tungsten, cobalt, and nickel, either singly or in combination, and optionally combined with ceramic or Teflon to provide a coating layer.
