자동차용 냉매 압축기의 사판과 피스톤의 표면 처리 구조{Surface management of swash plate and piston in compressor for vehicle}Surface treatment structure of swash plate and piston of vehicle refrigerant compressor {Surface management of swash plate and piston in compressor for vehicle}

본 발명은 자동차용 냉매 압축기의 사판과 피스톤의 표면 처리 구조에 관한 것으로 더욱 상세하게는 압축기내에서 고속 회전하는 사판과 이와 습동하는 피스톤의 표면 처리 구조에 관한 것이다.The present invention relates to a surface treatment structure of a swash plate and a piston of an automobile refrigerant compressor, and more particularly, to a surface treatment structure of a swash plate rotating at a high speed in a compressor and a piston that slides therein.

일반적으로 자동차는 동,하절기 적정 실내 기온의 유지를 위해 에어컨 시스템 및 히터 시스템으로 구성된 공조 장치를 구비하며,In general, the vehicle is equipped with an air conditioning system and an air conditioning system composed of an air conditioning system and a heater system to maintain the appropriate indoor temperature during the winter and summer.

상기 공조장치중 에어컨 시스템은 특정 냉매의 기화열을 이용하여 주위 공기의 냉각을 통해 실내 온도를 유지하는 것으로,The air conditioning system of the air conditioner is to maintain the room temperature by cooling the ambient air using the heat of vaporization of a specific refrigerant,

상기 에어컨 시스템중 기화한 냉매를 다시 액화하기에 용이한 환경으로 압축하는 사판식 냉매압축기(1)는;The swash plate-type refrigerant compressor (1) for compressing the vaporized refrigerant in the air conditioning system to an environment that is easy to liquefy again;

도 1에서와 같이 원통형의 하우징(10)에 양측면으로는 냉매의 기밀과 유동을 위한 프론트 및 리어 커버(11,11')가 구비되고,As shown in FIG. 1, both sides of the cylindrical housing 10 are provided with front and rear covers 11 and 11 ′ for airtightness and flow of the refrigerant.

상기 하우징(10) 내방에는 블록(12)에 의해 구획되는 방사형의 양측방으로 형성된 다수 개의 실린더(13)와 피스톤(14)이 형성된다.Inside the housing 10, a plurality of cylinders 13 and pistons 14 formed in both radial sides defined by the block 12 are formed.

상기 실린더(13)와 피스톤(14)등이 위치한 하우징(10)내부의 횡방향으로는 엔진의 구동력을 풀리로부터 전달받아 회전하는 샤프트(15)가 위치한다.In the transverse direction inside the housing 10 in which the cylinder 13 and the piston 14 are located, the shaft 15 which receives the driving force of the engine from the pulley and rotates is located.

상기 샤프트(15)상에는 일정 경사각을 형성한 원반형의 사판(16)이 구비되며,On the shaft 15 is provided a disk-shaped swash plate 16 having a predetermined inclination angle,

상기 사판(16)과 실린더(13)내의 피스톤(14)은 반구형 슈우(17)에 의해 체결되어 사판(16)의 회전운동에 대하여 피스톤(14)이 왕복운동 하게끔 구비한다.The swash plate 16 and the piston 14 in the cylinder 13 are fastened by the hemispherical shoe 17 so that the piston 14 reciprocates with respect to the rotational movement of the swash plate 16.

상기 하우징(10)의 양측면에 형성된 커버(11)에는 밸브 플레이트(18)에 의해 구획되는 흡입실(19)과 배출실(20)이 위치하며,In the cover 11 formed on both sides of the housing 10, the suction chamber 19 and the discharge chamber 20 partitioned by the valve plate 18 is located,

이들 흡입실(19)과 배출실(20)에는 냉매의 유입과 배출을 제어하는 디스차지밸브(21)와 석션밸브(22)가 장착되고, 상기 디스차지 밸브(21)는 디스차지 리테이너(23)에 의해 단속된다.The suction chamber 19 and the discharge chamber 20 are equipped with a discharge valve 21 and a suction valve 22 for controlling the inflow and discharge of the refrigerant, and the discharge valve 21 is a discharge retainer 23. It is interrupted by).

상기 사판식 냉매압축기(1)는 엔진의 구동력을 이용한 샤프트(15)의 회전에 따라 이와 체결된 사판(16)이 동반 회전하며,The swash plate-type refrigerant compressor (1) is rotated with the swash plate (16) fastened thereto in accordance with the rotation of the shaft (15) using the driving force of the engine,

상기 사판(16)과 반구형 슈우(17)로 연결된 피스톤(14)이 실린더(13)내에서 왕복 운동하며 냉매를 압축하여 배출실(20)로 토출한다.The piston 14 connected to the swash plate 16 and the hemispherical shoe 17 reciprocates in the cylinder 13, compresses the refrigerant, and discharges the refrigerant into the discharge chamber 20.

상기와 같은 일련의 작용들은 일정한 각도를 가지는 샤프트(15)에 압입된 알루미늄(Al)재질의 사판(16)이 회전함으로 인해,Such a series of actions are due to the rotation of the swash plate 16 of aluminum (Al) material pressed into the shaft 15 having a constant angle,

이와 반구형 슈(17)로서 개재된 피스톤(14)이 사판(16)의 회전 운동을 직선 왕복운동으로 전환함으로서 가능해진다.The piston 14 interposed as the hemispherical shoe 17 is made possible by converting the rotational motion of the swash plate 16 into a linear reciprocating motion.

상기와 같은 압축기(1)는 사판(16)의 회전과 피스톤의 직선 왕복을 통해 압축시 냉매에 의해 생성된 압력이 피스톤(14)과 슈(17)를 통하여 사판(16)에 전달되며, 이러한 압력으로 인해 슈(17)와 사판(16)의 접촉면에는 상당량의 회전 및 마찰력이 작용한다.In the compressor 1 as described above, the pressure generated by the refrigerant during the compression through the rotation of the swash plate 16 and the linear reciprocation of the piston is transmitted to the swash plate 16 through the piston 14 and the shoe 17. Due to the pressure, a considerable amount of rotational and frictional forces act on the contact surfaces of the shoe 17 and the swash plate 16.

상기와 같이 회전력과 마찰력이 지속적으로 작용하는 슈(17)와 사판(16)은 내마모성 향상을 위해,As described above, the shoe 17 and the swash plate 16 that the rotational force and the friction force continuously act to improve wear resistance,

슈(17)는 베어링강을 그 재질로 사용하며 사판(16)은 규소(Si)를 다량 함유한 알루미늄(Al)합금을 그 재질로 하여 표면에는 초기 윤활성을 향상시키기 위해 주석(Sn)코팅 처리하여 사용된다.The shoe 17 is made of bearing steel as its material, and the swash plate 16 is made of aluminum (Al) alloy containing a large amount of silicon (Si), and is coated with tin (Sn) to improve initial lubricity on the surface. Is used.

하지만, 사판(16)과 슈(17)의 재질이 가지는 강도의 편차로 인해 슈의 마모는 극히 일부지만,However, due to the variation in the strength of the material of the swash plate 16 and the shoe 17, the wear of the shoe is very small,

규소를 다량 함유한 알루미늄 합금의 사판(16)은 상대적으로 많은 마모량으로 인해 장시간 사용시 마찰음이 증가하여 공조 장치의 소음 증가 원인으로 작용하였다.The swash plate 16 of the aluminum alloy containing a large amount of silicon increased frictional sound when used for a long time due to a relatively large amount of abrasion, thereby acting as an increase in noise of the air conditioning apparatus.

이는 사판(16)이 고속회전체이므로 고비중의 경질 재료를 사용할 경우 압축기에 작용하는 하중 증가와 웨이트 밸런스의 제어가 난이하여 경질의 재료를 사용할 수 밖에 없는 특성으로 기인한다.This is because the swash plate 16 is a high-speed rotating body because when using a high specific gravity hard material, the load increase and weight balance acting on the compressor is difficult to control and the hard material must be used.

특히 저온시 냉매와 윤활용 냉매 오일이 상분리되며 분리된 오일이 압축기 외부로 빠져 나가는 현상인 프레온 마이그레이션(freon migration)현상으로 인해,In particular, due to the Freon migration phenomenon in which the refrigerant and the lubricating refrigerant oil are phase separated at a low temperature and the separated oil escapes to the outside of the compressor.

압축기의 재가동시 오일이 냉매와 혼합되어 회귀되는 시간동안 슈와 사판의 접촉면에는 무윤활 상태에서 작동한다.When the compressor is restarted, it operates without lubrication at the contact surface between the shoe and the swash plate during the time when oil is mixed with the refrigerant and returned.

이로 인하여 슈와 사판의 접촉면이 마찰열에 의해 소착되어 압축기의 작동이 불가능한 경우가 빈번히 발생하였다.As a result, the contact surface between the shoe and the swash plate is sintered by frictional heat, and thus the compressor cannot be operated frequently.

이에 본 발명에서는 상기한 문제점을 해결하기 위해 사판을 비롯한 슈와 피스톤의 상호 습동 부위 표면에 열처리와 더불어 저마찰계수를 가지는 금속성분의 코팅재를 도포하여 소착방지 및 습동의 원활성을 확보하여 압축기의 소음 방지 및 내구성 증대를 그 목적으로 한다.In the present invention, in order to solve the above problems, by applying a coating material of a metal component having a low coefficient of friction with heat treatment on the surface of the mutual sliding of the shoe and the piston including the swash plate to prevent seizure and smooth the sliding of the compressor It aims at preventing noise and increasing durability.

도 2 및 도 3에서와 같이 개략 원통형의 피스톤(30)과,2 and 3, a schematic cylindrical piston 30,

상기 피스톤(30)의 중앙부에 사판(40)을 수용하기 위한 사판 수용홈(31) 및 피스톤(30)과 사판(40)을 연계하는 매개체인 반원형 슈(50)의 볼 포켓(32)이 형성된다.A swash plate receiving groove 31 for accommodating the swash plate 40 at the center of the piston 30 and a ball pocket 32 of the semicircular shoe 50 which is a medium for connecting the piston 30 and the swash plate 40 are formed. do.

상기와 같이 반원형 슈(50)를 통해 피스톤(30)과 연결된 사판(40)은 중심에 샤프트(41)를 관통 구비하여 엔진의 구동력으로서 회전하여 피스톤(30)을 왕복 운동하도록 한다.As described above, the swash plate 40 connected to the piston 30 through the semi-circular shoe 50 is provided with a shaft 41 at the center thereof to rotate as a driving force of the engine to reciprocate the piston 30.

상기와 같은 사판(40)을 비롯한 슈(50)와 피스톤(30)은 상호 일정한 부위를 습동하면서 냉매를 압축하는데 특히 사판(40)과 슈(50)가 습동하는 사판(40)의 측면인 사판면(42)과,The shoe 50 and the piston 30, including the swash plate 40 as described above, compress the refrigerant while sliding certain portions of the swash plate 40, in particular, the swash plate 40 which is the side of the swash plate 40 on which the swash plate 40 and the shoe 50 slide. Cotton 42,

슈(50)와 피스톤(30)이 접촉하는 피스톤(30)의 볼 포켓부(32)는 냉매 압축기의 구동과 함께 상시 습동하는 부위이다.The ball pocket 32 of the piston 30, in which the shoe 50 and the piston 30 come into contact, is a portion that constantly slides together with the driving of the refrigerant compressor.

그리하여 사판면(42)과 슈(50)의 평면부(51),Thus, the flat portion 51 of the swash plate surface 42 and the shoe 50,

슈(50)의 반원면(52)과 피스톤(30)의 볼 포켓부(32)에는 내마모성 및 저마찰계수를 실현하기 위해,In the semicircular surface 52 of the shoe 50 and the ball pocket 32 of the piston 30, in order to realize wear resistance and a low coefficient of friction,

사판(40)은 알루미늄 합금으로 제작한 후 내마모성의 향상을 목적으로 산화 피막을 형성하기 위해 1차적으로 아노다이징(anodizing)처리를 수행하여 사판의 전반에 걸쳐 산화 피막에 의한 내마모성을 가지도록 한다.After the swash plate 40 is made of an aluminum alloy, the swash plate 40 is primarily subjected to an anodizing treatment to form an oxide film for the purpose of improving abrasion resistance.

참고적으로 아노다이징(anodizing)은 양극처리(陽極處理)라고도 하며 금속 표면을 청정화하거나 연마 산화처리를 할 때 전해액 속에서 그 당해 금속을 양극에 설치하고 불활성 금속을 음극으로 하여 전류를 통하는 처리법의 일종이다.For reference, anodizing is also called anodizing. It is a kind of treatment method in which the metal is installed in the anode in the electrolyte and the current flows through the inert metal as the cathode when the metal surface is cleaned or polished and oxidized. to be.

또한 슈(50)와 습동하는 사판면(42)에는 저마찰계수를 실현하기 위해 2차적으로 이황화몰리브덴(MoS2)을 주성분으로 하는 코팅재를 더 도포하여 내마모성 및 윤활성을 증대시키도록 한다.In addition, the swash plate surface 42 that slides with the shoe 50 is further coated with a coating material containing molybdenum disulfide (MoS 2 ) as a main component in order to realize a low coefficient of friction to increase wear resistance and lubricity.

상기와 같이 사판(40)의 전면과 사판면(42)의 표면 처리를 통해 강도와 내마모성등이 증가하여 이와 습동하는 슈(50)와의 윤활성이 증대된다.As described above, the strength and wear resistance of the swash plate 40 and the swash plate surface 42 are increased, thereby improving lubricity with the shoe 50 that slides.

상기와 같이 사판(40)의 표면 처리와 베어링강을 통해 제작된 슈(50)의 재질이 가지는 특성으로 이들 두 부품간의 마모는 현저히 저하되었으나,As described above, due to the characteristics of the material of the shoe 50 manufactured through the surface treatment of the swash plate 40 and the bearing steel, wear between these two parts was significantly reduced.

알루미늄재질의 피스톤(30)과 슈(50)의 습동부위인 볼 포켓(32)에는 마모현상이 활발히 진행하며,Abrasion phenomenon actively progresses in the ball pocket 32, which is a sliding part of the piston 30 and the shoe 50 made of aluminum,

이를 억제하기 피스톤(30)의 볼 포켓(32)에도 사판(40)과 동일한 1차적으로 아노다이징처리를 수행하고 이어 저마찰계수를 가지는 이황화몰리브덴(MoS2)를 도포하여 내마모성 및 윤활성의 향상을 도모한다.To suppress this, the ball pocket 32 of the piston 30 is subjected to the same anodizing treatment as that of the swash plate 40, followed by the application of molybdenum disulfide (MoS 2 ) having a low friction coefficient to improve wear resistance and lubricity. do.

냉매 압축기의 일시 정지로 인한 저온 현상시 유발되는 프레온 마이그레이션상태와 같은 무급유하에서도 소착과 같은 문제점 발생을 최소화하여 압축기의 내구성증대를 이룰 수 있다.The durability of the compressor can be increased by minimizing the occurrence of problems such as ignition even under no lubrication such as the Freon migration state caused by the low temperature phenomenon caused by the pause of the refrigerant compressor.

이상과 같은 본 발명인 자동차용 냉매 압축기의 사판과 피스톤의 표면 처리 구조는 사판을 비롯한 슈와 피스톤의 내마모성과 내부식성 및 윤활성을 향상시켜 압축기의 내구성 증대와 작동 소음을 현격히 저감시킬 수 있는 유용한 발명이다.Surface treatment structure of the swash plate and the piston of the refrigerant compressor for automobiles as described above is a useful invention that can significantly increase the durability of the compressor and reduce the operating noise by improving the wear resistance, corrosion resistance and lubricity of the shoe and piston, including the swash plate. .
