Description

자동차 엔진의 크랭크샤프트 베어링{a crank shaft bearing of engine in a vehicle}Crankshaft bearing of a car engine

본 발명은 엔진의 크랭크샤프트 베어링에 관한 것으로, 특히 크랭크샤프트로부터의 충격을 흡수하고 크랭크샤프트와의 접촉면에 보다 고르고 충분한 유막을 형성할 수 있도록 된 엔진의 크랭크샤프트 베어링에 관한 것이다.TECHNICAL FIELD The present invention relates to crankshaft bearings in engines, and more particularly to crankshaft bearings in engines that are capable of absorbing shock from the crankshaft and forming a more even and sufficient oil film on the contact surface with the crankshaft.

일반적으로 크랭크샤프트에 관계되는 베어링은 두 가지가 있는 바, 하나는 엔진의 실린더블럭에 설치되어 크랭크샤프트의 저어널부를 지지하는 메인베어링이고, 다른 하나는 커넥팅로드와 크랭크샤프트를 연결하는 크랭크핀을 지지하는 커넥팅로드 베어링이다.Generally, there are two bearings related to the crankshaft. One is the main bearing which is installed on the cylinder block of the engine and supports the journal part of the crankshaft. The other is the crankpin connecting the connecting rod and the crankshaft. Supporting connecting rod bearing.

이들 크랭크샤프트 베어링들은 도 1에 도시된 바와 같이, 단일체로 이루어진 베어링몸체(100) 내주면 중앙에 원주방향을 따라 오일통로(110)가 형성되고, 오일통로(110)를 따라 몇 개의 오일홀(120)이 형성된 구조로 이루어져 있다.(이와 같은 반원통형상을 가지는 상부베어링과 하부베어링이 합쳐져 완전한 베어링을 이루나, 도면에는 하부베어링만을 도시하였으며, 이는 본 발명의 설명에 있어서도 같다.)These crankshaft bearings, as shown in Figure 1, the oil passage 110 is formed along the circumferential direction in the center of the inner peripheral surface of the bearing body 100 consisting of a single body, several oil holes 120 along the oil passage 110 (The upper and lower bearings having such a semi-cylindrical shape are combined to form a complete bearing, but only the lower bearing is shown in the drawing, which is also the same in the description of the present invention.)

따라서, 메인베어링에 있어서는 실린더블록의 오일통로로부터 메인베어링캡을 거쳐 상기 오일홀(120)을 통해 오일이 공급되고, 커넥팅로드 베어링에 있어서는 커넥팅로드 대단부 내부에 형성된 오일통로로부터 상기 오일홀(120)을 통해 오일이 공급되며, 상기 오일홀(120)로 흘러든 오일은 오일통로(110)를 매개로 베어링 내주면 전체로 공급되어 유막을 형성하여 크랭크샤프트의 회전에 따른 마찰력을 감소시키게 된다.Therefore, in the main bearing, oil is supplied from the oil passage of the cylinder block through the main bearing cap to the oil hole 120, and in the connecting rod bearing, the oil hole 120 is formed from the oil passage formed inside the connecting rod end. The oil is supplied through the oil, and the oil flowing into the oil hole 120 is supplied to the entire inner circumferential surface of the bearing through the oil passage 110 to form an oil film to reduce frictional force due to the rotation of the crankshaft.

그러나, 실제로는 의도한 바와 달리 오일통로(110)가 베어링의 내측면 중앙에 형성되어 있기 때문에 중앙부분에만 충분한 유막이 형성되고, 외측부분에는 오일이 제대로 공급되지 않아 전체적으로 고르게 충분한 두께의 유막이 형성되지 않기 때문에 크랭크샤프트의 저어널부와 크랭크핀 및 베어링 자체의 마모가 심해지는 문제점이 있었다.However, in reality, since the oil passage 110 is formed in the center of the inner surface of the bearing, a sufficient oil film is formed only at the center portion, and oil is not supplied properly to the outer portion, so an oil film having a sufficient thickness is formed throughout. Since the journal part of the crankshaft and the crank pin and the bearing itself are not worn, there is a problem that the wear.

또한, 종래의 베어링에는 크랭크샤프트로 전달되는 폭발압력을 완화하는 어떤 구조도 적용되어 있지 않으므로 커넥팅로드와 베어링 및 크랭크샤프트를 충격으로부터 보호하거나 폭발에 의한 엔진의 충격진동을 감쇄시키는 면에 있어서도 바람직하지 못하다는 문제점이 있었다.In addition, the conventional bearings do not have any structure to relieve the explosion pressure transmitted to the crankshaft, which is undesirable in terms of protecting the connecting rod, the bearing and the crankshaft from impact, or reducing the impact vibration of the engine due to the explosion. There was a problem.

이에 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 크랭크샤프트의 저어널부 또는 크랭크핀과의 마찰면 전체에 고르게 유막이 형성되고, 이들로부터 전해지는 충격을 흡수할 수 있도록 된 자동차 엔진의 크랭크샤프트 베어링을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, the oil film is evenly formed on the entire surface of the crankshaft journal portion or the friction surface with the crank pins, the automobile engine of which is able to absorb the shock transmitted from them The purpose is to provide a crankshaft bearing.

상기와 같은 목적을 달성하기 위한 본 발명은, 내측베어링과, 이 내측베어링을 감싸는 외측베어링으로 이루어지며, 내측베어링의 몸체 양측과 외측베어링의 양측 플랜지 사이에 각각 오일통로가 형성되고, 외측베어링에 지지되어 내측베어링을 탄성지지하는 스프링이 구비되며, 상기 내측베어링의 플랜지가 외측베어링에 직접 접촉하지 않도록 외측베어링의 몸체와 플랜지에 각각 지지부재가 부착되고, 상기외측베어링의 몸체에 오일홀이 형성되는 구조로 이루어진다.The present invention for achieving the above object is made of an inner bearing and an outer bearing surrounding the inner bearing, the oil passage is formed between the body both sides of the inner bearing and both flanges of the outer bearing, respectively, A spring is supported and elastically supports the inner bearing. A support member is attached to the body and the flange of the outer bearing so that the flange of the inner bearing does not directly contact the outer bearing. An oil hole is formed in the body of the outer bearing. It is made of a structure.

따라서, 상기 오일홀을 통해 내측베어링과 외측베어링의 내측공간으로 유입된 오일은 상기 두 개의 오일통로를 통해 베어링의 내면 전체에 고르게 공급됨으로써 베어링의 마찰면 전체에 고른 유막을 형성할 수 있게 되고, 상기 스프링과 지지부재에 의하여 작동중의 충격을 흡수할 수 있게 된다.Accordingly, the oil introduced into the inner space of the inner bearing and the outer bearing through the oil hole is evenly supplied to the entire inner surface of the bearing through the two oil passages, thereby forming an even oil film on the entire friction surface of the bearing. The spring and the support member can absorb the shock during operation.

이하, 본 발명을 첨부된 예시도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

도 2는 본 발명에 따른 크랭크샤프트 베어링의 사시도로서, 본 발명은 내측베어링(20)과, 이 내측베어링(20)을 감싸는 외측베어링(10)으로 이루어진다.Figure 2 is a perspective view of a crankshaft bearing according to the present invention, the present invention consists of an inner bearing 20, and an outer bearing 10 surrounding the inner bearing 20.

상기 내측베어링(20)의 양측 벽면에는 바깥쪽을 향하는 플랜지(21)가 형성되고, 상기 외측베어링(10)의 양측 벽면에는 안쪽을 향하는 플랜지(11)가 형성되어, 이 플랜지(11,21)들이 소정 거리의 간격을 두고 서로 겹쳐지는 상태로 외측베어링(10)과 내측베어링(20)이 결합된다.Flange 21 facing outwards is formed on both side walls of the inner bearing 20, and flange 11 facing inward is formed on both side walls of the outer bearing 10, and the flanges 11 and 21 are formed. The outer bearing 10 and the inner bearing 20 are coupled to each other in a state where they overlap each other at a predetermined distance.

따라서, 외측베어링(10)과 내측베어링(20) 사이에는 빈 공간이 형성되고, 이 빈 공간에 연결되는 상기 플랜지(11,21)들 사이의 틈이 오일통로(30)로서 작용하게 된다.Therefore, an empty space is formed between the outer bearing 10 and the inner bearing 20, and the gap between the flanges 11 and 21 connected to the empty space acts as the oil passage 30.

따라서, 상기 오일통로(30)는 베어링(외측베어링과 내측베어링의 합체상태를 의미한다)의 마찰면 양측부에 각각 형성된다.Therefore, the oil passage 30 is formed on both sides of the friction surface of the bearing (meaning the combined state of the outer bearing and the inner bearing).

한편, 상기 외측베어링(10)과 내측베어링(20) 사이의 빈 공간으로 오일이 유입되는 오일홀(40)은 외측베어링(10)의 몸체 중간부분에 형성된다.On the other hand, the oil hole 40 is introduced into the empty space between the outer bearing 10 and the inner bearing 20 is formed in the middle of the body of the outer bearing (10).

상기 오일홀(40)이 형성된 부분에는 스프링(50)이 설치(스프링의 내측 공간에 오일홀(40)이 위치하도록)되어, 외측베어링(10)에 대하여 내측베어링(20)을 탄성지지한다.(도 3 및 도 4참조)A spring 50 is installed at the portion where the oil hole 40 is formed (to allow the oil hole 40 to be positioned in the inner space of the spring) to elastically support the inner bearing 20 with respect to the outer bearing 10. (See Figures 3 and 4)

또한, 상기 스프링(50)을 중심으로 양측으로 소정거리 떨어진 위치에는 외측베어링(10)과 내측베어링(20)의 사이에 내열성 고무재질로 이루어진 지지부재(60,70)가 설치되는데, 도 5에 도시된 바와 같이, 외측베어링(10)의 몸체와 내측베어링(20)의 플랜지(21) 사이에는 이 플랜지(21)와 폭이 같은 외측지지부재(60)가 설치되고, 외측베어링(10)의 플랜지(11)와 내측베어링(20)의 플랜지(21) 사이에는 이들이 겹쳐지는 면적과 같은 폭의 내측지지부재(70)가 설치된다. 여기서, 상기 외측지지부재(60)와 내측지지부재(70)는 모두 외측베어링(10)에 부착된다.In addition, the support member (60, 70) made of a heat-resistant rubber material is installed between the outer bearing 10 and the inner bearing 20 at a predetermined distance away from both sides with respect to the spring 50, Figure 5 As shown, between the body of the outer bearing 10 and the flange 21 of the inner bearing 20, an outer supporting member 60 having the same width as the flange 21 is provided, and the outer bearing 10 Between the flange 11 and the flange 21 of the inner bearing 20, an inner support member 70 having the same width as that of the overlapping area is provided. Here, the outer support member 60 and the inner support member 70 are all attached to the outer bearing 10.

이하, 본 발명의 작동을 설명한다.The operation of the present invention will be described below.

도 4와 도 5에 도시된 바와 같이, 크랭크샤프트의 저어널이나 크랭크핀으로부터 하중을 받지 않는 상태에서 상기 내측베어링(20)은 스프링(50)에 의해 베어링의 내측으로 밀려져 있는 상태이다. 이 상태에서 내측베어링(20)의 플랜지(21)는 내측지지부재(70)에 밀착되어 있으며, 이 내측지지부재(70)에 의해 내측베어링(20)의 플랜지(21)와 외측베어링(10)의 플랜지(11)가 직접 접촉되는 것이 방지되고 내측지지부재(70)의 두께만큼의 틈이 항상 존재하게 되므로 오일통로(30)는 막히지 않게 된다.As shown in FIGS. 4 and 5, the inner bearing 20 is pushed into the bearing by the spring 50 without being loaded from the journal or crank pin of the crankshaft. In this state, the flange 21 of the inner bearing 20 is in close contact with the inner supporting member 70, and the flange 21 and the outer bearing 10 of the inner bearing 20 are connected by the inner supporting member 70. Of the flange 11 is prevented from being in direct contact and the gap as much as the thickness of the inner support member 70 is always present, so that the oil passage 30 is not blocked.

한편, 도 6과 도 7에 도시된 바와 같이, 베어링이 크랭크샤프트(80, 정확히는 전술한 바와 같이 크랭크샤프트의 저어널과 크랭크핀)로부터 하중을 받는 상태에서는 스프링(40)을 압축시키면서 내측베어링(20)이 외측베어링(10)의 내부로 밀려들어가게 되며, 이 가압력에 의하여 베어링 내부의 빈 공간에 채워져 있던 오일이 오일통로(30)를 통하여 베어링의 마찰면으로 공급되는데, 오일통로(30)가 베어링의 양측면에 형성되어 있으므로 마찰면 전체에 보다 충분하고 고르게 유막이 형성된다.On the other hand, as shown in Figure 6 and 7, while the bearing is loaded from the crankshaft 80 (exactly the journal and crank pin of the crankshaft as described above) while compressing the spring 40 and the inner bearing ( 20) is pushed into the inside of the outer bearing 10, the oil filled in the empty space inside the bearing by this pressing force is supplied to the friction surface of the bearing through the oil passage 30, the oil passage 30 is Since they are formed on both sides of the bearing, an oil film is more evenly and evenly formed on the entire friction surface.

한편, 상기 내측베어링(20)이 밀려들어갈 때 스프링(50)에 의한 지지작용이 발생됨은 물론, 내측베어링(20)의 플랜지(21)가 상기 외측지지부재(60)에 충돌할 때 외측지지부재(60)가 탄성변형(압축변형)되면서 충격을 흡수하게 되므로 베어링 설치부위에서 발생하는 충격을 완화시킬 수 있게 된다.On the other hand, when the inner bearing 20 is pushed in, the support action by the spring 50 is generated, as well as the outer support member when the flange 21 of the inner bearing 20 collides with the outer support member 60. Since the 60 absorbs the shock while the elastic deformation (compression deformation), it is possible to mitigate the shock generated in the bearing installation portion.

여기서, 상기 외측지지부재(60)는 베어링의 원주방향으로 매우 작은 길이를 가지고 있으므로 전술한 내측지지부재(70)의 경우와 마찬가지로, 내측베어링(20)의 플랜지(21)가 외측지지부재(60)에 밀착되었다 하더라도 베어링의 내부공간과 상기 오일통로(30)가 막히는 것은 아니며, 항상 오일은 자유로이 이동할 수 있도록 되어 있다.Here, since the outer support member 60 has a very small length in the circumferential direction of the bearing, as in the case of the inner support member 70 described above, the flange 21 of the inner bearing 20 is the outer support member 60. Even if it is in close contact with), the inner space of the bearing and the oil passage (30) is not blocked, the oil is always able to move freely.

이상 설명한 바와 같이 본 발명에 따르면, 베어링의 마찰면에 오일을 공급하는 오일통로가 양측부에 각각 하나씩 모두 2개가 형성되므로 마찰면 전체에 오일이 충분히 공급되어 고르게 유막을 형성할 수 있게 됨으로써 크랭크샤프트의 저어널부나 크랭크핀 및 이들과 마찰되는 베어링면 자체의 마모를 방지할 수 있게 되며, 윤활막 끊김으로 인한 소음 및 진동발생을 방지할 수 있게 되는 효과가 있다.As described above, according to the present invention, since two oil passages for supplying oil to the friction surface of the bearing are formed at each of the two sides, the crankshaft can be formed evenly by supplying sufficient oil to the entire friction surface. It is possible to prevent the wear of the journal portion or the crank pin and the bearing surface itself friction with them, there is an effect that can prevent the generation of noise and vibration due to the lubrication film break.

또한, 작동시 크랭크샤프트측으로부터 하중을 전달받는 내측베어링이 외측베어링의 내부로 밀려들어갈 수 있으며, 이 내측베어링이 스프링과 외측지지부재에 의해 탄성지지됨으로써 충격량을 완화할 수 있게 되는 효과가 있다.In addition, during operation, the inner bearing receiving the load from the crankshaft side can be pushed into the inside of the outer bearing, and the inner bearing is elastically supported by the spring and the outer supporting member, thereby reducing the amount of impact.
