본 발명은, 가변 용량형 사판식 압축기에 관한 것으로서, 보다 상세하게는 구동부의 로터와 사판의 힌지 결합 구조가 개선된 가변 용량형 사판식 압축기에 관 한 것이다. The present invention relates to a variable displacement swash plate type compressor, and more particularly, to a variable displacement type swash plate type compressor having an improved hinge coupling structure of a rotor and a swash plate of a drive unit.

일반적인 가변 용량형 사판식 압축기(101)는 도 1에 도시된 바와 같이, 복수의 실린더보어(111)가 형성된 실린더블록(110)과, 실린더블록(110)의 전방(도면상 좌측)에 결합되어 실린더블록(110)과 함께 크랭크실(121)을 형성하는 전방하우징(120)과, 실린더블록(110)의 후방(도면상 우측)에 결합되며 내부에 흡입실(131)과 토출실(133)이 형성되어 있는 후방하우징(130)과, 실린더보어(111)에 각각 왕복이동 가능하게 수용된 복수의 피스톤(140)과, 피스톤(140)의 왕복운동에 따라 실린더보어(111)와 흡입실(131) 및 토출실(133)의 냉매유로를 개폐하는 밸브유닛(145)과, 피스톤(140)들을 왕복 구동시키는 구동부(150)를 포함하고 있다. The general variable displacement swash plate type compressor 101 is coupled to the cylinder block 110 in which the plurality of cylinder bores 111 are formed, and the front (left side in the drawing) of the cylinder block 110, as shown in FIG. The front housing 120 that forms the crank chamber 121 together with the cylinder block 110, and is coupled to the rear (right side in the drawing) of the cylinder block 110, and the suction chamber 131 and the discharge chamber 133 therein. The rear housing 130 and the plurality of piston 140 accommodated in the cylinder bore reciprocally, and the cylinder bore 111 and the suction chamber 131 according to the reciprocating motion of the piston 140 are formed. ) And a valve unit 145 for opening and closing the refrigerant passage of the discharge chamber 133, and a driving unit 150 for reciprocating the pistons 140.

이 중 구동부(150)는 도 1 및 도 2에 도시된 바와 같이, 크랭크실(121) 중앙 영역에 회전 가능하게 설치되어 외부 동력원으로부터 전달되는 구동력에 의해 회전하는 회전축(151)과, 회전축(151)에 대해 왕복 슬라이딩 및 회전 가능하게 결합된 슬리브(159)와, 슬리브(159)에 회동 가능하게 결합되어 회전축(151)에 대해 경사각이 가변 되는 사판(152)과, 크랭크실(121) 내에서 회전축(151)에 결합되어 회전축(151)과 함께 회전하면서 사판(152)의 경사각 가변운동을 지지하는 로터(155)와, 로터(155)에 대해 사판(152)을 원위치로 탄성 가압하는 사판가압스프링(158)으로 이루어져 있다. 1 and 2, the driving unit 150 is rotatably installed in the central region of the crank chamber 121 and rotates by a driving force transmitted from an external power source, and the rotating shaft 151. In the crank chamber 121 and the sleeve 159 reciprocally slidably and rotatably coupled to the swash plate, the swash plate 152 rotatably coupled to the sleeve 159 to vary the inclination angle with respect to the rotation axis 151. Rotor 155 is coupled to the rotary shaft 151 to rotate with the rotary shaft 151 to support the variable angle of inclination of the swash plate 152, and the swash plate pressure to elastically press the swash plate 152 to the original position with respect to the rotor 155 It consists of a spring 158.

여기서, 사판(152)의 경사각 조절은 후방하우징(130)에 설치된 컨트롤밸 브(135) 조작에 의한 크랭크실(121)의 압력 변화에 따라 조절된다. Here, the inclination angle adjustment of the swash plate 152 is adjusted according to the pressure change of the crank chamber 121 by the control valve 135 installed on the rear housing 130.

한편, 로터(155)에는 그 둘레 일영역으로부터 사판(152) 측을 향해 소정의 각도로 돌출된 로터힌지암(156)이 형성되어 있고, 이에 대응하는 사판(152)에는 그 둘레 일영역으로부터 로터(155) 측을 향해 소정의 각도록 돌출된 한 쌍의 사판힌지암(153)이 형성되어 있다. On the other hand, the rotor 155 is formed with a rotor hinge arm 156 protruding at a predetermined angle from one peripheral area toward the swash plate 152 side, and the corresponding swash plate 152 has a rotor from one peripheral area thereof. A pair of swash plate hinge arms 153 which protrude to a predetermined angle toward the 155 side is formed.

로터힌지암(156)에는 장공상의 경사각 가변 가이드공(157)이 형성되어 있으며, 사판힌지암(153)에는 로터힌지암(156)의 경사각 가변 가이드공(157)에 유동 가능하게 삽입된 힌지핀(154)이 결합되어 있다. The rotor hinge arm 156 has a long inclined variable guide hole 157 is formed, the swash plate hinge arm 153 is hinged to be inserted into the variable variable inclined guide hole 157 of the rotor hinge arm 156 Pin 154 is coupled.

이러한 가변 용량형 사판식 압축기의 구동부(150)는 외부 동력원으로부터 전달되는 구동력에 의해 회전축(151)이 회전하면, 회전축(151)과 함께 로터(155)가 회전하고, 로터(155)의 회전에 의해 사판(152)이 회전축(151)의 길이방향을 따라 왕복 슬라이딩 이동하면서 경사각이 가변된다. When the rotating shaft 151 rotates by the driving force transmitted from an external power source, the driving unit 150 of the variable displacement swash plate type compressor rotates together with the rotating shaft 151 to rotate the rotor 155. As a result, the inclination angle is varied while the swash plate 152 reciprocates sliding along the longitudinal direction of the rotation shaft 151.

그리고, 사판(152)이 경사각 가변되면서 회전하면 사판(152)의 둘레영역은 피스톤(140)의 브릿지(143)에 개재된 슈(141)에 대해 자유회전하면서 피스톤(140)들을 왕복 이동시킨다. 이에 의해, 가변 용량형 사판식 압축기(101)의 흡입 및 압축행정이 실행된다. When the swash plate 152 rotates while the inclination angle is changed, the circumferential region of the swash plate 152 reciprocates the pistons 140 while freely rotating with respect to the shoe 141 interposed in the bridge 143 of the piston 140. As a result, the suction and compression stroke of the variable displacement swash plate compressor 101 is executed.

이때, 사판(152)이 회전함과 동시에 크랭크실(121)의 압력과 사판가압스프링(158)의 탄성력, 사판의 관성 모멘트의 합력의 작용에 의해 사판힌지암(153)의 힌지핀(154)이 로터힌지암(156)의 경사각 가변 가이드공(157) 내에서 슬라이딩 되 며 사판(152)의 경사각이 가변된다.At this time, the hinge pin 154 of the swash plate hinge arm 153 by the action of the force of the crank chamber 121 and the elastic force of the swash plate pressing spring 158, the moment of inertia of the swash plate as the swash plate 152 rotates. The inclination angle of the rotor hinge arm 156 is slid in the variable guide hole 157 and the inclination angle of the swash plate 152 is variable.

그런데, 이러한 종래 가변 용량형 사판식 압축기에 있어서는 사판힌지암(153)과 로터힌지암(156)의 결합 상태에서 양 사판힌지암(153) 사이에 로터힌지암(156)의 양 측면이 면 접촉된 상태로 결합되기 때문에, 압축기(101)의 구동시 로터힌지암(156)과 사판힌지암(153)의 접촉면에서 마찰력이 발생하여 진동과 소음을 발생시키는 문제점이 있었다. However, in the conventional variable displacement swash plate type compressor, both sides of the rotor hinge arm 156 are in surface contact between the swash plate hinge arms 153 and the two swash plate hinge arms 153 in a coupled state of the swash plate hinge arm 153 and the rotor hinge arm 156. Because of the combined state, the friction force is generated at the contact surface between the rotor hinge arm 156 and the swash plate hinge arm 153 when the compressor 101 is driven, thereby generating vibration and noise.

또한, 로터힌지암(156)과 사판힌지암(153)의 접촉면에서 마찰력에 의한 마모가 발생하여 로터힌지암(156)과 사판힌지암(153)의 내구성을 저하시키는 문제점이 있었다. In addition, abrasion caused by friction occurs at the contact surface between the rotor hinge arm 156 and the swash plate hinge arm 153, thereby lowering the durability of the rotor hinge arm 156 and the swash plate hinge arm 153.

따라서, 본 발명의 목적은, 로터힌지암과 사판힌지암의 마찰저항을 최소화하여 진동과 소음을 방지함과 동시에, 내구성을 향상시킬 수 있는 가변 용량형 사판식 압축기를 제공하는 것이다. Accordingly, an object of the present invention is to provide a variable displacement swash plate type compressor capable of minimizing the frictional resistance between the rotor hinge arm and the swash plate hinge arm to prevent vibration and noise and at the same time improve durability.

상기 목적은, 본 발명에 따라, 회전축(151)과, 상기 회전축(151)과 함께 회전하며 로터힌지암(35)을 갖는 로터(30)와, 상기 로터힌지암(35)과 힌지핀(154)에 의해 슬라이딩 가능하게 결합되는 사판힌지암(25)에 의해 상기 회전축(151)에 대하여 경사각이 가변되는 사판(20)을 포함하는 가변 용량형 사판식 압축기에 있어서, 상기 로터힌지암(35)과 상기 사판힌지암(25)의 상호 대향하는 양 접촉면 중 적어도 어느 일측에는 윤활부(50)가 형성되어 있는 것을 특징으로 하는 가변 용량형 사판식 압축기에 의해 달성된다.The object is, according to the present invention, the rotor 30, the rotor 30 and the rotor hinge arm 35 and rotates together with the rotary shaft 151, the rotor hinge arm 35 and the hinge pin 154 In the variable displacement swash plate type compressor including a swash plate 20 is inclined angle with respect to the rotation axis 151 by the swash plate hinge arm 25 is slidably coupled by the), the rotor hinge arm (35) And a lubrication part 50 is formed on at least one side of the two contact surfaces of the swash plate hinge arm 25 which are opposed to each other.

여기서, 상기 윤활부(50)는 윤활홈(51)으로 이루어지는 것이 바람직하다. Here, the lubrication portion 50 is preferably made of a lubrication groove (51).

또는, 상기 윤활부(50)는 상기 로터힌지암(35)에 형성된 적어도 하나의 슬릿형상의 윤활홈(51)과, 상기 사판힌지암(25)에 상기 윤활홈(51)을 향해 관통 형성된 적어도 하나의 오일유입공(53)으로 이루어지는 것이 효과적이다. Alternatively, the lubrication part 50 may include at least one slit-shaped lubrication groove 51 formed in the rotor hinge arm 35 and at least formed through the swash plate hinge arm 25 toward the lubrication groove 51. It is effective to consist of one oil inlet hole (53).

이하에서는 첨부된 도면을 참고하여 본 발명에 대해서 상세하게 설명한다. 이때, 구동부의 사판과 로터의 힌지 결합 구조를 제외한 가변 용량형 사판식 압축기의 나머지 구성은 전술한 종래 가변 용량형 사판식 압축기의 구성과 거의 동일하므로 그 자세한 설명은 생략하고, 구동부의 사판과 로터 및 이들의 힌지 결합 구성 외의 구성요소에 대한 도면부호는 전술한 도 1 및 도 2의 도면부호를 이용한다. Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.
