The present invention relates to a swash plate and a bearing lubrication structure of a swash plate compressor, and more particularly, a through hole is formed in a bearing formed in a swash plate of a swash plate compressor, and a plurality of ball bearings are inserted into the through hole to form a piston and a swash plate. The present invention relates to a swash plate and a bearing lubrication structure of a swash plate type compressor in which a ball bearing inserted into the through hole is rotated in contact with a friction part while lubricating through oil is made therebetween.

일반적으로, 자동차용 냉방장치를 구성하는 압축기에는 왕복동식 압축기, 크랭크식 압축기, 사판식 압축기등이 있으며 사판식 압축기는 자동차 쿨러의 냉매를 압축하는데 사용하는 왕복형 압축기의 일종으로, 회전샤프트의 회전에 따라 사판도 함께 회전함으로서 에어컨 냉매의 흡입, 압축작업을 하게된다.In general, compressors constituting the air conditioner for automobiles include a reciprocating compressor, a crank compressor, a swash plate compressor, and the like. The swash plate compressor is a type of reciprocating compressor used to compress refrigerant of an automobile cooler. As the swash plate also rotates, the air conditioner refrigerant is sucked and compressed.

상기와 같은 사판식 압축기의 종래 구성은 도 1에 도시된 바와같이 프론트하우징(10)과 리어하우징(20)의 중앙부에 횡방향으로 설치되어 회전하는 샤프트(30)에 경사지게 사판(40)이 결합하고, 상기 샤프트(30)와 함께 회전하는 사판(40)의 양측 단부에 오일이 스며들 수 있도록 가이드홈(50)을 형성하여 반구형상의 베어링(60)을 삽입하고, 직선 왕복운동하는 다수의 피스톤(70)에 사판의 양측 단부가 삽입되며, 상기 피스톤(70)이 실린더실(80) 내부에서 작동하도록 설치된 실린더(82)와 상기 베어링(60)과 접촉하는 사판(40)사이에 오일이 윤활하여 작동하도록 구성된다. In the conventional configuration of the swash plate type compressor as described above, as shown in FIG. 1, the swash plate 40 is inclined to the shaft 30 which is installed in the transverse direction at the center of the front housing 10 and the rear housing 20 to rotate. And a guide groove 50 for inserting oil into both ends of the swash plate 40 rotating together with the shaft 30 to insert a hemispherical bearing 60 and a plurality of pistons to linearly reciprocate. Both ends of the swash plate are inserted into the 70, and oil is lubricated between the cylinder 82 installed so that the piston 70 operates inside the cylinder chamber 80 and the swash plate 40 in contact with the bearing 60. Is configured to operate.

그러나, 이와 같은 종래의 사판식 압축기의 베어링(60)과 사판(40)사이의 윤활구조는 사판(40)과 직선 왕복운동하는 피스톤(70)과의 접촉면이 베어링(60)과 맞닿아 있어서, 상기 접촉부위에 윤활이 잘 이루어지지 않아 고속회전을 하는 사판(40)과 베어링(60) 사이에 심한소음이 발생하였다.However, in the lubrication structure between the bearing 60 and the swash plate 40 of the conventional swash plate type compressor, the contact surface between the swash plate 40 and the piston 70 linearly reciprocating is in contact with the bearing 60, Lubricating was not performed well on the contact part, and severe noise was generated between the swash plate 40 and the bearing 60 which rotate at high speed.

따라서, 엔진과 함께 작동되는 압축기는 여름철과 같이 더운 계절에 에어컨을 작동시킬 경우 압축기의 구동에 따른 사판과 베어링 사이의 마찰로 인해 기계적 소음을 유발하였으며 차량의 연비를 떨어뜨리는 주요 원인이 되었다.Therefore, when the air conditioner is operated in a hot season such as summer, the compressor operated with the engine causes mechanical noise due to the friction between the swash plate and the bearing caused by the driving of the compressor and has been a major cause of lowering the fuel efficiency of the vehicle.

또한, 상기 사판과 베어링 사이에 윤활이 충분히 이루어지지 않아서 베어링의 마모를 유발하였으며 압축기의 고장의 문제점을 발생시켰다.In addition, insufficient lubrication between the swash plate and the bearing caused wear of the bearing and caused a problem of failure of the compressor.

본 발명은 상기와 같은 문제점을 해결하고자 발명된 것으로서, 사판식 압축기의 사판에 형성된 베어링 내부로 수평한 관통홀을 형성하고, 관통홀 내부로 볼 베어링을 다수개 삽입하여 피스톤과 사판사이의 접촉면에 오일을 통한 윤활이 이루어짐과 동시에 볼 베어링이 마찰부위와 접촉하여 회전함으로 인하여 접촉면의 마찰과 마모를 방지하는 사판식 압축기의 사판과 베어링 윤활구조를 제공하는 것을 목적으로 한다. The present invention has been invented to solve the above problems, to form a horizontal through-hole into the bearing formed in the swash plate of the swash plate compressor, and insert a plurality of ball bearings into the through hole in the contact surface between the piston and the swash plate It is an object of the present invention to provide a swash plate and bearing lubrication structure of a swash plate type compressor which prevents friction and wear of the contact surface due to lubrication through oil and rotation of the ball bearing in contact with the friction part.

상기한 목적을 달성하기 위해 본 발명은 프론트하우징과 리어하우징의 중앙부에 횡방향으로 설치되어 회전하는 샤프트에 경사지게 사판이 결합하고, 상기 샤프트와 함께 회전하는 사판의 양측 단부에 오일이 스며들 수 있도록 가이드홈을 형성하여 반구형상의 베어링을 삽입하고, 직선 왕복 운동하는 다수의 피스톤에 사판의 양측 단부가 삽입되며, 상기 피스톤이 실린더실 내부에서 작동하도록 설치된 실린더와 상기 베어링과 접촉하는 사판사이에 오일이 윤활하여 작동하는 사판식 압축기의 윤활구조에 있어서, 상기 베어링 내부로 수평하게 다수의 관통홀을 형성하고, 관통홀 내부로 볼 베어링이 다수개 삽입되어 구성되는 것을 특징으로 하는 사판식 압축기의 사판과 베어링 윤활구조가 구성된다. In order to achieve the above object, the present invention is installed in the center portion of the front housing and the rear housing in the transverse direction so that the swash plate is inclined to the rotating shaft, so that oil can penetrate both ends of the swash plate rotating with the shaft A guide groove is formed to insert a hemispherical bearing, and both ends of the swash plate are inserted into a plurality of linear reciprocating pistons, and oil is disposed between the cylinder and the swash plate which are in contact with the bearing. In the lubrication structure of the swash plate type compressor that operates by lubrication, the swash plate type of swash plate type compressor comprising: a plurality of through holes horizontally formed inside the bearing, and a plurality of ball bearings are inserted into the through holes; Bearing lubrication structure is constructed.                     

이하 본 발명인 사판식 압축기의 사판과 베어링 윤활구조는 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the swash plate and bearing lubrication structure of the swash plate compressor of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 사판식 압축기의 사판과 베어링 윤활구조를 나타낸 단면도로서, 본 발명은 프론트하우징(10)과 리어하우징(20)의 중앙부에 횡방향으로 설치되어 회전하는 샤프트(30)에 경사지게 사판(40)이 결합하고, 상기 샤프트(30)와 함께 회전하는 사판(40)의 양측 단부에 오일이 스며들 수 있도록 가이드홈(50)을 형성하여 반구형상의 베어링(60)을 삽입하고, 직선 왕복운동하는 다수의 피스톤(70)에 사판(40)의 양측 단부가 삽입되며, 상기 피스톤(70)이 실린더실(80) 내부에서 작동하도록 설치된 실린더(82)와 상기 베어링(60)과 접촉하는 사판(40)사이에 오일이 윤활하여 작동하는 사판식 압축기의 윤활구조에 있어서, 상기 베어링(600) 내부로 수평하게 다수의 관통홀(100)을 형성하고, 관통홀(100) 내부로 볼 베어링(110)이 다수개 삽입되어 구성된다.2 is a cross-sectional view showing the swash plate and the bearing lubrication structure of the swash plate compressor according to the present invention, the present invention is installed in the central portion of the front housing 10 and the rear housing 20 in the transverse direction in the rotating shaft 30 The swash plate 40 is inclined to be coupled, and guide grooves 50 are formed to insert oil into both ends of the swash plate 40 rotating together with the shaft 30 to insert the hemispherical bearing 60, Both ends of the swash plate 40 are inserted into the plurality of pistons 70 linearly reciprocating, and the cylinders 70 are installed in contact with the bearings 60 and the cylinders 82 installed to operate in the cylinder chamber 80. In the lubrication structure of the swash plate type compressor in which oil is lubricated between the swash plates 40, the plurality of through holes 100 are formed horizontally into the bearing 600, and the ball is inserted into the through holes 100. A plurality of bearings 110 are inserted.

그리고, 상기 관통홀(100) 사이로 오일이 흐를 수 있으며 상기 관통홀(100)에 볼 베어링(110)을 삽입하되, 관통홀(100)에서 볼 베어링(110)이 빠지지 않고 회전할 수 있도록 관통홀(100)의 직경을 형성하는것이 바람직하다.In addition, oil may flow between the through holes 100, and the ball bearing 110 is inserted into the through holes 100, but the through holes may rotate in the through holes 100 without falling out. It is preferable to form the diameter of (100).

상기 볼 베어링(110)은 사판(400)의 회전 궤적과 직각으로 접촉하여 구름작용을 하는 것이 바람직하다.The ball bearing 110 is preferably in contact with the rotational trajectory of the swash plate 400 to perform a rolling action.

그리고, 상기 베어링(600)이 삽입되는 사판(400)의 양측 단부에는 오일이 흐를수 있도록 유동홀(120)이 형성되고, 상기 유동홀(120)에 교차되어 상, 하로 형성된 오일홈(102a)을 포함되는 구조로 구성된다. In addition, flow holes 120 are formed at both ends of the swash plate 400 into which the bearing 600 is inserted so that oil flows, and the oil grooves 102a formed up and down by crossing the flow holes 120. It consists of a structure that includes.                     

상기 오일홈(102a)은 사판식 압축기 정지시에 오일이 상기 오일홈(102a)에 머물러 있다가 압축기 구동시에 사판(400)의 회전과 더불어 중력에 의해 유동홀(120)의 양측으로 흘러서 작동되는 것이 바람직하다.The oil groove 102a is operated by flowing oil to both sides of the flow hole 120 by gravity together with rotation of the swash plate 400 when the swash plate compressor stops and the oil stays in the oil groove 102a when the swash plate compressor is stopped. It is preferable.

이와 같이 구성된 본 고안의 사판식 압축기의 사판과 베어링 윤활구조의 작용에 대해 상세히 설명한다.The operation of the swash plate and the bearing lubrication structure of the swash plate compressor of the present invention configured as described above will be described in detail.

그리고, 이하 설명은 사판식 압축기의 사판과 접촉하는 베어링 및 피스톤과 이루어지는 윤활구조의 작용에 대해서 설명하겠다.In the following description, the operation of the lubrication structure of the bearing and the piston in contact with the swash plate of the swash plate type compressor will be described.

우선, 도 2에서와 같이 샤프트(300)가 회전하게 되면 이와 결합된 사판(40)이 회전하고 이 회전운동은 피스톤(700)을 직선 왕복운동으로 변환시킨다.First, as shown in FIG. 2, when the shaft 300 rotates, the swash plate 40 coupled thereto rotates, and this rotational motion converts the piston 700 into a linear reciprocating motion.

이때, 상기 사판(40)에는 양측에 설치된 베어링(600)의 관통홀(100)에 삽입된 볼 베어링(110)이 함께 회전하고, 이러한 볼 베어링(110)의 회전은 사판(400)과 베어링(600), 그리고 피스톤(700) 사이에 발생되는 마찰을 볼 베어링(110)이 회전함으로서 억제하게된다.At this time, the swash plate 40 is rotated together with the ball bearing 110 inserted into the through hole 100 of the bearing 600 installed on both sides, the rotation of the ball bearing 110 is the swash plate 400 and the bearing ( 600 and the friction generated between the piston 700 is suppressed by the rotation of the ball bearing 110.

그리고, 상기 볼 베어링(110)의 회전과 더불어서 가이드홈(50)을 따라 오일이 스며들고, 스며든 오일은 사판(40)에 형성된 유동홀(120)을 따라서 순환하여 볼 베어링(110)과 사판(40)면과의 접촉부위에서 발생하는 마모를 방지하게 된다.In addition, along with the rotation of the ball bearing 110, oil is permeated along the guide groove 50, and the permeated oil circulates along the flow hole 120 formed in the swash plate 40 to circulate the ball bearing 110 and the swash plate. (40) It prevents abrasion occurring at the contact area with the surface.

그리고 , 상기 사판식 압축기가 작동하지 않고 정지해 있을 때에도 사판(40)에 형성된 가이드홈(50)과 유동홀(120)과 교차되어 형성된 오일홈(102a)에 오일이 잔류하고 있어서, 압축기 재가동시에도 사판(400)과 베어링(600)과의 접촉면에 잔류된 오일에 의해 원할히 작동하게 된다. Further, even when the swash plate compressor is stopped without operation, oil remains in the guide groove 50 formed in the swash plate 40 and the oil groove 102a formed to intersect the flow hole 120, so that the compressor is restarted. The oil remaining on the contact surface between the plate 400 and the bearing 600 is smoothly operated.
