[0002]

2. Description of the Related Art Japanese Patent Publication No. 61-1636,
As disclosed in Japanese Patent Publication No. 1-193780, a piston in a swash plate type compressor is reciprocated by a rotating operation of a swash plate that rotates integrally with a rotating shaft. A shoe is interposed between the front and rear end surfaces of the swash plate and the piston, and the rotational force of the swash plate is transmitted to the piston via the shoe. Since a shoe made of an iron-based material comes into sliding contact with the rotating swash plate, the sliding contact portion between the shoe and the swash plate may be worn or seizure may occur between the shoe and the swash plate. Therefore, it is necessary to improve the slidability of the swash plate with respect to the shoe.

In the compressor disclosed in Japanese Patent Publication No. 61-1636, the flat portion of a hemispherical shoe is formed as a convex curved surface having an extremely large radius of curvature, and the first and second peripheral surfaces of the convex curved surface are first and second.
Is provided. The inclination angle of the second chamfered portion inside the first chamfered portion is smaller than the inclination angle of the first chamfered portion. The first and second chamfers have a function of drawing oil on the end face of the swash plate that comes into sliding contact with the shoe between the shoe and the end face of the swash plate. The configuration in which a large amount of oil is drawn between the shoe and the end surface of the swash plate improves the slidability of the swash plate with respect to the shoe.

In order to further improve the slidability of the swash plate with respect to the shoe, in the swash plate disclosed in Japanese Patent Application Laid-Open No. H11-193780, a sliding contact excellent in sliding property is provided on front and rear end surfaces of the swash plate which is in sliding contact with the shoe. A membrane is provided.

[0005]

[0006] Foreign matter (grinding chips, abrasion powder, etc. during part grinding) in the compressor and the external refrigerant circuit.
Therefore, a measure is taken to dispose a filter on the passage of the refrigerant gas as disclosed in JP-A-6-336978.
In order to avoid clogging in the filter, a filter capable of filtering only foreign matters having a certain size or more is used. Foreign matter that has passed through such a filter may enter between the swash plate and the shoe. In a compressor in which a swash plate is provided with a sliding contact film, the sliding contact film may be damaged depending on the size of foreign matter that has entered between the swash plate and the shoe. If the sliding contact film is damaged, the sliding contact property of the sliding contact film is reduced.

SUMMARY OF THE INVENTION It is an object of the present invention to prevent foreign matter from exerting an adverse effect of reducing the sliding property of a sliding contact film.

[0007]

For this purpose, the present invention provides a shoe having a flat surface contacting a swash plate that rotates integrally with a rotating shaft and a spherical portion fitted into a fitting recess of a piston. Interposed between the plate and the piston, the rotational force of the swash plate is transmitted to the piston via the shoe to reciprocate the piston, and a sliding contact film is formed on a sliding contact area of the swash plate with the shoe. In the invention according to claim 1, a main chamfered portion is provided on an outer peripheral side of a flat surface portion of the shoe, and a tilt angle of the main chamfered portion with respect to a plane contacting the center of the flat surface portion is predetermined. , And the maximum distance between the main chamfered portion and the plane is set to be equal to or less than the thickness of the sliding contact film.

In the main chamfered portion in which the inclination angle with respect to the plane contacting the center of the flat surface portion is equal to or less than a predetermined angle, the distance from the flat surface is less than the thickness of the sliding contact film. When foreign matter having a diameter smaller than the thickness of the sliding contact film enters between the main chamfered portion and the swash plate, the foreign matter is completely embedded in the sliding contact film, so that the foreign matter is sandwiched between the shoe and the swash plate. There is no rolling in the state. When foreign matter having a diameter larger than the thickness of the sliding contact film enters between the main chamfered part and the swash plate, the foreign matter may roll while being sandwiched between the shoe and the swash plate, The sliding contact film may be damaged. Thus, the foreign matter having a diameter larger than the thickness of the sliding contact film damages the sliding contact film,
It is difficult for foreign matter having a diameter larger than the thickness of the sliding contact film to enter between the main chamfered portion and the swash plate.

According to the invention of claim 2, in claim 1,
A sub-chamfer is provided so as to surround the main chamfer and to be continuous with the main chamfer, and the inclination angle of the sub-chamfer is larger than the predetermined angle.

The sub-chamfered portion in which the inclination angle with respect to the plane tangent to the center of the flat surface portion is larger than a predetermined angle is effective for drawing oil between the flat surface portion and the swash plate. Further, since the inclination angle is large, the foreign matter that has contacted the sub-chamfered portion is stopped there and does not enter the inside of the shoe.

According to a third aspect of the present invention, in any one of the first and second aspects, the flat surface portion includes a convex surface portion having an inclination angle with respect to the plane equal to or less than an inclination angle of the main chamfered portion. It consisted of a main chamfer.

The convex portion contributes to oil drawing between the swash plate and the central portion of the flat surface portion. According to a fourth aspect of the present invention, in any one of the first to third aspects, the predetermined angle is 20 °.

When the inclination angle of the main chamfer exceeds 20 °,
Even if foreign matter having a diameter larger than the thickness of the sliding contact film enters between the main chamfered portion and the swash plate, there is almost no risk of damaging the sliding contact film.

According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the sliding contact film includes a metal layer formed on a surface of a sliding contact area of the swash plate, And a resin layer containing a solid lubricant formed thereon.

The resin layer is particularly effective in a non-lubricating oil state, but is easily damaged by foreign matter. It is difficult for foreign matter having a diameter larger than the thickness of the sliding contact film to enter between the main chamfered portion and the resin layer on the swash plate.

According to a sixth aspect of the present invention, in the fifth aspect,
The swash plate was made of an iron-based material, and the metal layer was made of an aluminum-based or copper-based material. Aluminum-based or copper-based materials are suitable for the metal layer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

FIG. 1A shows the internal structure of the variable displacement compressor. A rotating shaft 13 is supported on the front housing 12 and the cylinder block 11 forming the control pressure chamber 121. The rotating shaft 13 obtains a rotational driving force from an external driving source (for example, a vehicle engine). A rotating support 14 is fixed to the rotating shaft 13, and a swash plate 15 is attached to the rotating shaft 13.
Are supported so as to be slidable and tiltable in the axial direction. A support 151 is formed integrally with the swash plate 15 made of an iron-based material, and a guide pin 16 is fixed to the support 151. The guide pin 16 is slidably fitted in a guide hole 141 formed in the rotary support 14. The swash plate 15 can be tilted in the axial direction of the rotating shaft 13 by the cooperation of the guide hole 141 and the guide pin 16 and
3 and can be integrally rotated. The inclination of the swash plate 15 is determined by the sliding guide relationship between the guide hole 141 and the guide pin 16,
And, it is guided by the slide supporting action of the rotating shaft 13.

The inclination angle of the swash plate 15 can be changed based on pressure control in the control pressure chamber 121. When the pressure in the control pressure chamber 121 increases, the inclination angle of the swash plate 15 decreases, and the control pressure chamber 121
When the internal pressure decreases, the inclination angle of the swash plate 15 increases. The refrigerant in the control pressure chamber 121 flows out to the suction chamber 191 in the rear housing 19 via a pressure release passage (not shown), and the refrigerant in the discharge chamber 192 in the rear housing 19 passes through a pressure supply passage (not shown). The pressure can be supplied to the control pressure chamber 121 via the control pressure chamber 121. A capacity control valve 25 is interposed on the pressure supply passage, and the flow rate of the refrigerant supplied from the discharge chamber 192 to the control pressure chamber 121 is controlled by the capacity control valve 25. When the flow rate of the refrigerant supplied from the discharge chamber 192 to the control pressure chamber 121 increases, the pressure in the control pressure chamber 121 increases, and the discharge chamber 19
When the flow rate of the refrigerant supplied from 2 to the control pressure chamber 121 decreases, the pressure in the control pressure chamber 121 decreases. That is, the swash plate 15
Is controlled by the capacity control valve 25.

The maximum inclination angle of the swash plate 15 is defined by the contact between the swash plate 15 and the rotary support 14. The minimum inclination angle of the swash plate 15 is defined by the contact between the circlip 24 on the rotating shaft 13 and the swash plate 15.

In the cylinder block 11, the rotating shaft 13
A plurality of cylinder bores 111 [only two are shown in FIG. Each cylinder bore 11
1 accommodates a piston 17. A holding portion 171 is formed on the piston 17, and a pair of spherical fitting recesses 172 and 173 are formed on the holding portion 171. As shown in FIG. 1B, a hemispherical shoe 18A is irremovably held in the fitting recess 172, and a hemispherical shoe 18B is irremovably held in the fitting recess 173.

Rotational movement of the swash plate 15 which rotates integrally with the rotating shaft 13 is converted into forward and backward reciprocating movements of a piston 17 via hemispherical shoes 18A and 18B.
Moves back and forth in the cylinder bore 111. The shoe 18A made of an iron-based material is in sliding contact with one of the sliding surfaces 30 of the swash plate 15,
The shoe 18B made of an iron-based material is in sliding contact with the other sliding contact surface 31 of the swash plate 15.

The refrigerant in the suction chamber 191 moves backward from the piston 17 (moves from right to left in FIG. 1A).
As a result, the suction valve 211 on the valve forming plate 21 is pushed away from the suction port 201 on the valve plate 20 and flows into the cylinder bore 111. The refrigerant flowing into the cylinder bore 111 is moved by the forward movement of the piston 17 (moving from left to right in FIG. 1A) to the valve plate 2.
The discharge valve 202 on the valve forming plate 22 is pushed away from the discharge port 202 on the discharge port 202 to be discharged to the discharge chamber 192. The opening of the discharge valve 221 is regulated by contacting the retainer 231 on the retainer forming plate 23.

The discharge chamber 192 and the suction chamber 191 are connected via an external refrigerant circuit 26. The refrigerant flowing from the discharge chamber 192 to the external refrigerant circuit 26 returns to the suction chamber 191 via the condenser 27, the expansion valve 28, and the evaporator 29.

As shown in FIGS. 1A and 1B, end surfaces 152 and 15 of the swash plate 15 facing the cylinder block 11 are provided.

The metal layers 321 and 331 formed on 2,153 are made of an aluminum-based material mainly containing silicon-containing aluminum. The resin layers 322 and 332 formed on the metal layers 321 and 331 are made of a material in which a solid lubricant (for example, molybdenum disulfide, graphite or the like) is dispersed in a resin such as polyamideimide. That is, the sliding films 32 and 33 are formed by the swash plate 1.

The thickness of 1,331 is about 60 to 70 μm, and the thickness of the resin layers 322, 332 is about 10 to 20 μm. The thickness D of the sliding contact films 32 and 33 is about 70 to 90 μm.

As shown in FIG. 2, the hemispherical shoe 18
A and 18B are a flat surface portion 34 in contact with the swash plate 15 and a spherical portion 3 fitted in the fitting recesses 172 and 173 of the piston 17.
5 is provided. The flat surface portion 34 includes a spherical convex portion 341 having a very large radius of curvature, and an annular main chamfered portion 342 smoothly connected to the periphery of the convex portion 341. An annular sub-chamfer 36 is provided around the main chamfer 342.
Are formed so as to smoothly connect to the peripheral edge of the main chamfered portion 342.

FIG. 3 shows a flat surface portion 34 and a sub-chamfered portion 36.

Point P represents the center of the flat surface portion 34, and H represents a plane contacting the center P of the flat surface portion 34. The average of the inclination angle θ1 of the main chamfered portion 342 with respect to the plane H is about several degrees, and the
The average of the inclination angles θ2 is about 40 °. Tilt angle θ

It is larger than.

With the rotation of the swash plate 15, the shoes 18A, 1
The lubricating oil on the sliding contact surfaces 30 and 31 of the swash plate 15 which is swept by 8B is applied to the sub-chamfered portion 36 and the sliding contact surfaces 30 and 31 of the swash plate 15.
31 and between the main chamfered portion 342 and the sliding contact surfaces 30 and 31 of the swash plate 15 and between the convex surface portion 341 and the sliding contact surfaces 30 and 31 of the swash plate 15.

In the first embodiment, the following effects can be obtained. (1-1) The average of the inclination angle θ1 of the main chamfered portion 342 with respect to the plane H that is in contact with the center P of the flat surface portion 34 is as small as about several degrees, and the main chamfered portion 342 and the swash plate 15 having such a small inclination angle θ1. If foreign matter is caught between the metal and the base metal, the sliding contact films 32 and 33 are damaged. However, the maximum distance β between the main chamfered portion 342 and the sliding surfaces 30 and 31 is about 10 μm,
Foreign matter having a diameter larger than the film thickness D (about 70 to 90 μm) of the sliding contact films 32 and 33 is formed on the main chamfered portion 342 and the sliding contact surfaces 30 and 3.
It doesn't get in between 1.

On the other hand, foreign matter having a diameter larger than the thickness D of the sliding contact films 32 and 33 enters between the sub-chamfered portion 36 and the sliding contact surfaces 30 and 31. However, the sub-chamfer 3 for the plane H
In the configuration in which the average of the inclination angles θ2 of the reference numeral 6 is about 40 °, no foreign matter is caught between the sub-chamfered portion 36 and the sliding contact surfaces 30 and 31.

Therefore, foreign matter larger than the film thickness D which easily damages the sliding contact films 32 and 33 is caused by the metal of the swash plate 15 and the shoe 18.
Thus, the sliding contact films 32 and 33 are prevented from being damaged by foreign matter.

A test was conducted in which aluminum foreign matter and iron foreign matter were charged into the control pressure chamber 121, and the compressor was operated for one hour to check the resin layers 322 and 332 for damage. The total weight of the foreign matter is 12 mg, the weight ratio between the aluminum foreign matter and the iron foreign matter is 2: 1, and the maximum diameter of the foreign matter is 10
It was set to 0 μm. In this test, it was confirmed that the resin layers 322 and 332 did not wear.

(1-2) Sub-chamfer 3 having a large inclination angle θ2
6 is a swash plate 1 swept by the shoes 18A and 18B.
5 is effective in drawing the lubricating oil on the sliding contact surfaces 30, 31 between the flat surface portion 34 and the sliding contact surfaces 30, 31 of the swash plate 15.

(1-3) The average of the inclination angle θ2 of the sub-chamfered portion 36 is set to about 40 °, but if the inclination angle θ2 exceeds 20 °, the sub-chamfered portion 36 and the sliding contact surfaces 30, 31 are provided. Even if foreign matter having a diameter larger than the film thickness D of the sliding contact films 32, 33 enters between the sub-chamfered portion 36 and the sliding contact surfaces 30, 31,
It is not sandwiched between. That is, the inclination angle is 20
Even if a foreign matter having a diameter larger than the film thickness D enters between the chamfered portion exceeding the angle and the sliding contact surfaces 30 and 31 of the swash plate 15, the sliding contact films 32 and 33 are very unlikely to be damaged. Therefore, when the inclination angle θ2 of the sub-chamfered portion 36 exceeds 20 °, the main chamfered portion 342 and the sliding contact surfaces 30 and 32 are connected only when the inclination angle θ1 of the main chamfered portion 342 is 20 ° or less. Is set equal to or less than the film thickness D of the sliding contact films 32 and 33, the sliding contact films 32 and 33 are not damaged by foreign matter.

(1-4) The sliding contact between different kinds of materials is less likely to seize than the sliding contact between similar materials. Swash plate 15 made of iron-based material
An aluminum-based material, which is a different material from the above, is made of a metal layer 32 constituting the sliding contact films 32 and 33 in order to prevent seizure.
1,331 is suitable.

(1-5) The lubricating oil is drawn between the sliding contact surfaces 30, 31 of the swash plate 15 and the center of the flat surface portion 34 of the shoes 18A, 18B, thereby extending the life of the sliding contact films 32, 33. It is important in extending. The convex portion 341 plays a significant role in drawing lubricating oil between the sliding contact surfaces 30, 31 of the swash plate 15 and the center of the flat surface portion 34 of the shoes 18A, 18B.

(1-6) The sub-chamfer 36 prevents the shoes 18A, 18B from making an acute angle so as to contact the swash plate 15. That is, the sub-chamfered portion 36 is formed by the swash plate 15
It contributes to prevention of corner contact with 8A and 18B.
