【発明の詳細な説明】 ［産業上の利用分野］ 本発明は空調機器や冷凍機器等に用いられるロータリー

している。[Prior Art] In a rotary compressor, a camshaft 2 is rotatably held in a casing 1 and a rotor 4 is fitted around a cam portion 3 of the camshaft 2 as shown in Figs. . The rotor 4 is in contact with the lower end of a partition vane 6 elastically held by a spring 5 on the casing 1.

側とを仕切っている。When the camshaft 2 is rotated by a motor (not shown), the rotor 4 rotates along the inner wall of the cylinder of the casing 1, sucks gas such as refrigerant from the suction port 7 into the casing 1, compresses it, and discharges it from the discharge port 8. Discharge. During the rotation of the rotor 4, the partition vane 6 has its tip constantly pressed against the surface of the rotor 4 by the elastic force of the spring 5, thereby partitioning the suction side and the discharge side.

に対応できなくなってきている。[Problems to be Solved by the Invention] Since a rotary compressor made by using cast iron parts is heavy, not only is there a problem of increasing the weight of the entire equipment incorporated therein, but also a problem of the recent technology. With the progress, the inverter system has been adopted and the rotor is required to rotate at high speed, and cast iron rotors cannot cope with the increase in bearing load due to rotation of the rotor during high speed rotation.

ずしも十分とは言えなかった。Therefore, it has been proposed to make a rotor from an aluminum alloy or a titanium alloy having a small specific gravity and abrasion resistance. (Refer to JP-A-61-155687) These rotors and vanes made of lightweight and wear-resistant metal are advantageous in terms of reduction of inertial force during rotation and followability of partition vanes, but linear expansion. Since the coefficient is larger than that of iron, the gap between the cast iron casing and the sliding part tends to change due to temperature changes, not only there is the risk of gas leakage, but also the wear resistance compared to iron-based materials. It wasn't always enough.

In addition to the lightness inherent to aluminum-based metals, the inclusion of SiC whiskers dramatically improves mechanical strength and wear resistance, and the coefficient of linear expansion is similar to that of cast iron. In addition, since the structure of the obtained whisker reinforced metal (WRM) is extremely homogeneous and the orientation of the whisker components does not occur, phenomena such as abnormal wear and sliding failure due to component segregation do not occur.

When used by incorporating it into a rotary compressor having a casing made of an iron-based material, the compatibility is good, and the overall size and weight can be reduced. The partition vane does not cause a gap in the sliding part due to a mismatch in linear expansion with the casing, and has a high strength, resulting in a high safety factor by design.
Furthermore, since it is lightweight, there is no risk of the vane flying phenomenon, and the partition of suction and exhalation does not become insufficient.

荷が軽減され、設計的に小型化が可能となる。Further, since the rotor is lightweight, the inertial force is small, the bearing load is reduced, and the design can be downsized.
