1+, the swash plate rotated by the cylinder: dowel 1. ? A swash plate type comprising a screw fitted slidably into the inner part of the swash plate, and a shoe interposed between the piston and the swash plate to cause the piston to reciprocate as the swash plate rotates. Combrera is used. In this compressor, the swash plate rotates and oscillates due to the rotation of the rotating shaft, which causes the piston to reciprocate and compress the gas in the cylinder. In this swash plate type compressor, aluminum or aluminum alloy is generally used for the swash plate and shoes in order to reduce weight. Here, there is a large Mf on the sliding surfaces of the swash plate and shoes! Because of the high sliding speed and large sliding speed, the sliding movement of the swash plate and shoes poses a problem of seizure. In particular, since the aluminum or aluminum alloy that forms the base material of the swash plate and shoes tends to stick together, it may be difficult to operate without lubrication during startup or during severe WJI where the number of sliding layers is large.
Under dynamic conditions (there is a problem of low seizure resistance. [Objective of the invention] To provide a swash plate compressor that overcomes the above problems and has excellent seizure resistance. [Structure 1 of the Invention] In the swash plate compressor of the present invention, at least one of the swash plate and the shoe is made of aluminum or an aluminum alloy as a base material, and the sliding movement is caused by a solid body formed on the base material. The swash plate is composed of a surface of a lubricant layer. In the swash plate type compressor of the present invention, the swash plate is a member that is rotated and oscillated about the rotating shaft within the cylinder block. Shoe means a device that prevents the piston from reciprocating motion due to the sliding movement of the swash plate and the rotation of the swash plate.Therefore, the shoe may be either a hemispherical shoe or a flat shoe. The swash plate type compressor of the present invention only needs to have one component such as a swash plate, a shoe, a piston, a rotating shaft, and a cylinder block, and the shape etc. of these components may be the same as that of a conventional swash plate type compressor. At least one of the swash plates 1-, which characterizes the swash plate type compressor of the invention, is made of 1. aluminum or an aluminum alloy as a base material. Examples of the aluminum alloy include Al-1t!Si-based alloy, Al- S l
A 7Mu-based alloy, an AI-8i-C, u-Mq-based alloy, or a Δ1 alloy that does not contain S: can be used. m IJ
It is preferable to use a material containing hard coarse particles in an aluminum or aluminum alloy matrix. Here, hard coarse particles refer to those having a hardness of l-1v300 or more, preferably 600 or more, and an average particle size of 10μ or more, more preferably an average particle size of 20 to 100μ, such as There is primary silicon. Arcyl alloy is known as a typical matrix material containing hard coarse particles. This Alsil alloy has a silicon content of 13 to 30 ftt%l! i! It has a high silicon content below the eutectic composition and has primary silicon in the Other base materials containing hard coarse particles include aluminum-manganese intermetallic compounds, aluminum-silicon-manganese intermetallic compounds, aluminum-iron intermetallic compounds, aluminum-iron-manganese intermetallic compounds, and aluminum-chromium intermetallic compounds. There are aluminum alloys that contain hard coarse particles such as compounds. The base material is l1iI! In cases where coarse particles are included, for example, in the case of Alsil alloys containing primary silicon, the base material itself has excellent 18 dynamic properties, making it difficult for swash plates and shoes used in severe sliding conditions. Suitable as a base material. In this case, the base material may be an aluminum-silicon alloy having a low silicon content, for example, about 1% below the eutectic composition, and having no primary silicon in the matrix. The sliding movement of at least one of the swash plate and the shoe, which is a special feature of the swash plate type compressor of the present invention, is constituted by the surface of a solid lubricant layer formed on the base material. This solid lubricant layer coats the base material surface of the swash plate and shoe.
This is to prevent the base material surface of aluminum or aluminum alloy, which tends to cause adhesion, from being exposed in the sliding movement. The thickness and type of the solid lubricant layer are determined by taking into account conditions such as the magnitude of the load acting on the swash plate and shoes, and the sliding speed.The thickness of the solid lubricant layer is determined by Fl. Thick culms are preferred. In general, a good J Niji is about 2μ to 8μ. In addition, if lubricating oil is sufficiently supplied, sufficient durability can be achieved even when the thickness is relatively thin, about 0.5μ. For special applications, it may be preferable to increase the thickness of the solid lubricant layer to about 12 microns or more. The above-mentioned solid lubricant layer may be made by solidifying solid lubricant powder such as molybdenum disulfide, tungsten disulfide, graphite, boron nitride, lead oxide, or fluorine side i with resin, or It is best to plate the soft full bend. When solidifying with resin, the base material surface of the R1 plate or shoe is ground and polished, and an uncured thermosetting resin paste containing a solid lubricant is applied to the surface of the Zono 121 Shrine, and this is heated at room temperature or heated. The solid lubricant layer may be formed by solidification using other methods. In addition, as for the method of application, ordinary painting methods such as spray method, tampling method, roll coating method, and brush coating method can be used.As the resin, phenol resin, epoxy resin, furan resin, Thermosetting resins such as Yuria resin, polyamideimide resin, and unsaturated polyester are suitable.Also, depending on the conditions of use, thermosetting resins such as fluororesin, polyacetal resin, and nylon resin can also be used. When recesses are formed on the surface, the solid lubricant-forming components enter these four parts, and the solid lubricant layer firmly adheres to the base material due to the anchor effect.The surface of the base material on which the solid lubricant layer is formed is preferably covered with a hard coating. In this case, as shown in FIG. Based on this, for example, if a swash plate type compressor is operated for a considerable period of time under abnormal conditions where lubricant is not supplied, and the solid lubricant layer is worn out as a result, , a hard film will be exposed on the sliding surface.As a result, the base material of aluminum or aluminum alloy, which is easy to break, will not be exposed on the sliding surface of bamboo, making it highly resistant to burning and staining. Note that the hard coating may be formed only on the parts where the swash plate and shoes slide (or may be formed on the rests of the swash plate and shoes). It is preferable that the oxidized coating is hard anodized.
L, yes. Fi4 aluminum is generally dense and hard, so it has high wear resistance, and has good adhesion to the base material. As the anodic oxide coating for aluminum, a hard and dense bar 7 layer may be used.
Alternatively, porous ffffff'J may be formed on the Paris 17 layer. The aluminum anodic oxide film is 2μ~2
0μ is good. Anodizing methods include oxalic acid method, sulfuric acid method,
Test using the oxalic acid/sulfuric acid tear method, the muric acid method, etc. [Effects of the Invention] In the swash plate type hinge of the present invention, at least the sliding surface -h of the swash plate and shoe, in which the sliding strip A'1 is the most severe, is constituted by the surface of a solid lubricant layer. Therefore, the base materials of aluminum and aluminum alloys, which tend to adhere, are not exposed on the active surface. Therefore, the swash plate compressor of the present invention has excellent seizure resistance. In addition, if the swash plate compressor is operated under conditions where lubricating oil is not temporarily supplied, such as at the initial stage of startup, J3
Even when the shoes and swash plate are in contact with each other, seizure is prevented by the action of the solid fl quenching agent layer on the sliding surfaces of the shoes and the swash plate, and problems such as seizure can be prevented for a relatively long period of time. Therefore, the swash plate type umbrella tree of the present invention has superior durability. [Example] A cross-sectional view of a swash plate compressor according to an example of the present invention is shown in the second example.
As shown in the figure. In FIG. 2, 4 is a cylinder no.
．． The rotary shaft 5 is rotatably supported via the rotary shaft 7.
A swash plate 8 is connected and fixed by a pin 9. In the cylinder block '4, syringing bores 10 are formed at regular intervals of 120 mm, and a piston 11 is slidably fitted into each bore 10. The ti end ft1) of this cylinder tab 1) is cooled by the valve plates 1 to 12 and the front 1-cylinder head 13, and the right end opening is connected to the valve plate 14 and rear cylinder head 15. It's blocked. n'l fit! A concave portion 11a is formed in the center portion of the piston 11 to receive the outer peripheral portion of the swash plate 8, and a spherical concave portion 11b is formed on each axially opposing surface of the concave portion 11a. And on the sliding surface of the swash plate 8,
A spherical shoe 16 is in contact with lFt, and the 80 rotations of the swash plate are transmitted to the piston 11 as column II motion. The above configuration is basically the same as that of the conventional swash plate compressor 11. In this embodiment, the sliding surface of the swash plate 8 is different from the conventional one. , [111, the swash plate 8 according to this embodiment also has its lF
tWh is composed of a solid lubricant layer 18. The base material of this swash plate 8 is a Δ1-high Si alloy, and its surface is polished with Nagishi's U-rtll polish. The solid lubricant layer is made by hardening molybdenum disulfide, Grapheye 1~ with a phenol resin adhesive. In the swash plate type compressor of this example,
Shoe 16, which is the mating material for sliding, is made of 5UJ-2! In order to carry out an actual machine test of this swash plate type compressor, the swash plate type compressor was manufactured in the same manner as in the example, the lubricating oil was reduced to 10% of the normal amount, and the operating time was 1.
