Problems solved by technology

In addition, although the rollers are sometimes arranged to be embedded in the sleeve, in this case, the thickness of the sleeve near the embedded portion is limited by the diameter of the rollers and the diameter of the sleeve, and there is a possibility that the strength of the sleeve is insufficient.

no. 1 approach

[0050] Below, refer to figure 1 -4 The first embodiment of the present invention will be described.

[0051] Such as figure 1 As shown, the compressor 1 according to the embodiment of the present invention is an axial flow type or a centrifugal type compressor, and includes a cylindrical casing 2 and a casing 3 inserted into the casing 2 .

[0052] One end of the axis C1 direction of the shell 2 ( figure 1 The left side of ) is largely opened as an opening 2 a forming an entrance for inserting the sleeve 3 . That is, the sleeve 3 described later is inserted from one end toward the other end of the case 2 .

[0053] A plurality of (three in the illustrated example) suction nozzles 4 and one discharge nozzle 5 are protrudingly provided on the outer peripheral portion of the casing 2 . The above-mentioned suction nozzle 4 and one discharge nozzle 5 are installed so that the casing 2 is positioned at a predetermined height with respect to the installation surface G and the axi...

[0094] Next, refer to Figure 5 A second embodiment of the present invention will be described.

[0095] This embodiment differs from the compressor of the first embodiment only in the structure of the roller 11, and the other structures are the same as those of the first embodiment. In this embodiment, the same reference numerals and the like are attached to the same constituent elements as those in the first embodiment, and description thereof will be omitted.

[0096] Such as Figure 5 As shown, the roller 11 of the present embodiment includes the rotating shaft 21 and the roller body 22 similarly to the first embodiment, and the outer peripheral surface 23 of the roller body 22 of the present embodiment is formed so that the central part in the direction of the rotating shaft faces outward in the radial direction. Bulging convex surface. Furthermore, the convex curved surface is formed continuously from the center toward the end side of the outer peripheral surface 23 o...

no. 3 approach

[0109] Next, refer to Figure 7 and 8 describe a third embodiment of the present invention.

[0110] This embodiment differs from the structure of the second embodiment only in the structure of the roller main body 22, and the other structures are the same as those of the second embodiment. In this embodiment, the same reference numerals and the like are attached to the same constituent elements as those in the first embodiment, and description thereof will be omitted.

[0111] Such as Figure 7 As shown, the roller 11 of the present embodiment includes the rotating shaft 21 and the roller body 22 similarly to the second embodiment, and the outer peripheral surface 23 of the roller body 22 of the present embodiment is formed so that the central part in the direction of the rotating shaft faces outward in the radial direction. Bulging convex surface. Furthermore, the convex curved surface is formed continuously from the center toward the end side of the outer peripheral surf...

Abstract

The compressor of the present invention includes: a cylindrical casing; a casing (3) having a cylindrical stationary component and a rotating element accommodated in the stationary component, and the casing (3) is inserted into the casing; and a roller (11) that supports the sleeve (3) and rolls on the inner peripheral surface of the housing when the sleeve (3) is inserted into the inside of the housing in the axial direction, the roller (11 ) is formed as a continuous convex curved surface such that the radius of curvature of the end side of the roller (11) along the axis of rotation (21) is smaller than the radius of curvature of the center.

Description

technical field [0001] This invention relates to compressors for compressing fluids. [0002] this application claims priority based on Japanese Patent Application No. 2012-037722 for which it applied to Japan on February 23, 2012, and uses the content here. Background technique [0003] Among conventional compressors, there is a compressor configured by inserting a cylindrical bundle (compressor bundle) into a cylindrical housing (cabin) (for example, refer to Patent Document 1). , The kit is constructed by assembling a rotor, moving blades, and stator blades inside a cylindrical casing (kit casing). [0004] This type of compressor is assembled by inserting the sleeve into the housing along the axial direction from an opening provided on one end side of the housing in the axial direction. Conventionally, rollers that support the weight of the kit and roll in the axial direction on the inner peripheral surface of the casing when the kit is inserted into the housing are pr...
