(Field of Industrial Application) The present invention relates to a vane type compressor, and in particular to a material combination for a rotor and a side block, which reduces the weight while preventing wear and seizure. (Prior art) A vane type compressor closes the front and rear opening surfaces of a cylinder block with a pair of side blocks, and
It is known that the vanes are biased to protrude from the outer circumferential surface of the rotor toward the inner surface of the cylinder block, partition the approximately elliptical cylinder chamber so that its volume can be changed, and compress the gas within the partitioned area. There is. In recent years, vane type compressors that use aluminum materials (mainly Si--Al alloys) to reduce their weight have been proposed, for example, as shown in Japanese Unexamined Patent Publication No. 61-89991. (Problems to be Solved by the Invention) However, aluminum material has poor wear resistance and seizure resistance, and when aluminum material is used as a material for the rotor and side blocks, wear and seizure occur in the rubbing parts of both. The gas in the cylinder chamber leaked and the rotation of the rotor was hindered, so that it could not be put to practical use. (Means for Solving the Problems) The present invention employs the following technical means to solve the above problems. That is, the vane type compressor of the present invention is an air conditioning compressor for automobiles, and has at least a rotor and side blocks made of a Si-Al alloy, and has a Si content of 3% in the rotor and both side blocks. I made the above differences. The reason for limiting the difference in Si content to 3% or more is as follows.
This is based on the following knowledge that if the difference in Si content is less than 3%, wear and seizure occur during rubbing (when the compressor is driven). (Background of the invention) Phenomena of wear and seizure occur when two materials rub against each other, and the wear resistance and seizure resistance change when the combination of materials changes. It is generally known. Therefore, the present inventor developed Si-Al with different Si contents.
Alloy materials were combined and the seizure load was measured using a Falex seizure test. More specifically, as shown in FIG. 3, a pin 30 is made of one material, a block having a V-shaped groove is made of another material, and a block 31 is pressed against the pin 30 while rotating the pin 30. The load at the point when seizure occurred was measured. The test results are shown below along with the test conditions. Incidentally, the seizure load P is expressed as P=F/2√2, where the angle of the V-shaped groove is 90° and the force applied to the block 31 is F. Furthermore, the practical seizure load limit is 280Kg.

[Table] From the above test results table, it can be seen that in the case of the test in which the same materials were rubbed against each other, the seizure load was extremely small, and in the case of the test in which different materials with a Si content different by 3% or more were brought into sliding contact with each other, , it can be seen that the seizure load becomes extremely large (it has seizure resistance). This means that if the contained Si particle size and Si particle shape are about the same, the impact they receive from each other will be strong, resulting in particles breaking or falling off, leading to wear and seizure. It is understood that if the particle shapes differ to some extent, the above-mentioned impact is absorbed or idly rotated, thereby weakening the attacking force of each particle against the other particle, and increasing the limits of wear resistance and seizure resistance. The present invention was completed based on the findings based on the above test results. (Function) According to the above technical means, the Si-
Since there is a difference of more than 3% between the Si content of the Al alloy and the Si content of the Si alloy that forms the cylinder block, large wear and seizure will not occur in the sliding area between the vane and rotor. , as a result, lightweight Si−
Can be used in combination with Al alloy materials. (Example) The present invention will be described below based on an example shown in the drawings. FIG. 1 is a longitudinal sectional view of a compressor showing an embodiment of the present invention, and FIG. 2 is a sectional view taken along line A-A in FIG. The compressor main body 1 includes a front side block 3a and a rear side block 3b fixed to the front and rear sides of a cylinder block 2, and a cylinder chamber 4 is formed within the compressor main body 1.
The guide surface 5 of the cylinder chamber 4 has an oval shape or a shape close to this. The drive shaft 6 is fitted into a bearing hole 8 formed in a bearing portion 7 of the front side block 3a, and movement in the thrust direction is regulated by a bearing 9 interposed between the flange portion 6a and the bearing portion 7. Thus, the shaft 6 is rotatably supported by the compressor main body 1. Furthermore, a cylindrical rotor 10 arranged in the cylinder chamber 4 is fixed to the drive shaft 6, and for example, four vane grooves 11 are formed at equal intervals on the circumferential surface of the rotor 10. A vane 12 is slidably inserted into the vane groove 11. This vane 12 is urged toward the tip by back pressure from a back pressure chamber 13 provided below the vane groove 11, slides along the guide surface 5 of the cylinder chamber 4, and is moved between adjacent vanes 12. The compression chamber 14 thus formed is configured to expand and contract. The suction hole 15 and the discharge hole 16 are formed in each cylinder block 2, are arranged at positions facing each other, and open into the compression chamber 14. On the other hand, the compressor main body 1 is surrounded by a head 18 tightly fixed to the front side block 3a and a casing 19 tightly fixed to the head 18. A low pressure chamber 20 is formed between the head 18 and the front side block 3a, and the low pressure chamber 20 communicates with the suction hole 15 and the suction port 21. Further, a high pressure chamber 22 is formed in the casing 19, and the high pressure chamber 22 communicates with the discharge hole 16 and the discharge port 23, and the lower part of the high pressure chamber 22 is an oil reservoir 24. This oil reservoir 24 and the bearing hole 8 of the front side block 3a communicate with each other via an oil supply hole 25, and the oil is supplied to the gap between the drive shaft 6 and the bearing hole 8 by the pressure of the high pressure chamber 22. has been done. A part of the oil supplied to the gap between the drive shaft 6 and the bearing hole 8 flows into the seal chamber 26, and is further supplied to the cylinder chamber 4 through the oil supply hole 27 formed in the front side block 3a. It is used to lubricate the gap between the front side block 3a and the rotor 10, the guide surface 5, etc. and 20% as the material for forming the vane 12.
A lighter 12% Si-Al alloy material (casting material) is used as the material for forming the rotor 10, and a 16% Si-Al alloy material (casting material) is used as the material for forming the cylinder block 2. Alloy material (powder extrusion material) is used. Therefore, the compressor of the present invention is considerably lightweight as a whole. The compressor of the present invention is incorporated into an automobile (not shown) for use in air conditioning, and during this use, troubles due to wear and seizure do not occur for a long period of time. Incidentally, the Si content rates described in the examples are not necessarily limited to those mentioned above, and the Si content rates may be varied by 3% or more. (Effects of the Invention) As explained above, according to the present invention, since the rotor and cylinder block are made of lightweight Si-Al alloy material, the compressor can be made lightweight, and the rotor and cylinder block are made of lightweight Si-Al alloy material. Since the Si content of the cylinder block forming materials differs by more than 3%,
Wear and seizure are less likely to occur between the rotor and cylinder block, and as a result, troubles such as compressed refrigerant leakage and the rotor's inability to rotate are prevented.
This has the effect of extending the life of the compressor.
