Embodiment Construction

[0045] 1. Embodiment (Structure of Rotary Compressor)

[0046] Hereinafter, the space in which each configuration of the rotary compressor 9 is arranged will be shown in an xyz right-handed coordinate system in the drawings in order to describe the arrangement of the configurations. Among the coordinate marks shown in the drawings, a circle mark with a black circle in which the inside is white indicates an arrow extending from the far side toward the near side of the paper. A circle mark that is white inside and has two crossed lines drawn in it represents an arrow extending from the near side to the far side of the paper. In space, a direction parallel to the x-axis will be referred to as the x-axis direction. In the x-axis direction, a direction in which the x component increases will be referred to as a +x direction, and a direction in which the x component decreases will be referred to as a -x direction. In addition, regarding the y component and the z component, the y-a...

Abstract

A first closing member (2) and a second closing member (3) close openings at both axial ends of a cylindrical member (1). A substrate (411) is accommodated in a space formed by the cylindrical member (1), the first closing member (2), and the second closing member (3), and the substrate (411) rotates about an axis along the same direction as the axial direction of the cylindrical member (1). A resin layer (410) is formed in a thrust surface of the substrate (411). A groove (C) comprises a plurality of concentric annular grooves or a spiraling groove forming concentric circles in the resin layer (410), and the center of the rings of the annular grooves or the center of the spiral of the spiraling groove is different from the rotational center of the substrate (411).

Description

technical field [0001] The present invention relates to rotors and rotary fluid machines. Background technique [0002] There are known rotary fluid machines that suck and discharge fluid by moving a rotor and vanes in a space formed by closing both ends of a cylinder. With these rotary fluid machines, there is a need to prevent rotor seizure and wear. As a technique for solving this problem, for example, Patent Document 1 describes a rotary compressor having a modified surface layer by making the inner circumference of the cylinder and the outer circumference of the rotor separate by using sulfur nitriding treatment or vulcanization treatment. Either or both are modified to form the modified surface.
