Abstract

PURPOSE: Reinforced structure in durability of a vane pump is provided to reinforce durability by fast rotation with lengthening a vane. CONSTITUTION: A vane pump consists of: a housing(1) having a circular opened accepting hole, and suction/discharge ports; a rotatable shaft(2) mounted at the accepting hole of the housing with eccentricity; a rotor(3) mounted to a spline(2a) of the rotatable shaft, having connecting grooves(2a',3a); a couple of sealing members(5) inserted into the connecting grooves to improve durability; vanes(4,4') rising or falling radially; and a cover(6) sealed with the housing to expose the rotatable shaft having the rotor accepting the vanes. The vanes slide in opposite to each other by a strong centrifugal force of the fast rotating rotor in the accepting hole of the housing. Oil is drained to the discharge port from the suction port by vacuum states. The rotatable shaft, the sealing members and the vanes are connected each other to prevent vibration caused by a gap between the vanes and the connecting hole of the rotor. The vanes have length as long as the length of protrusions(4a,4a'). Therefore, the radial sliding length of the vanes is increase by centrifugal force.

Description

베인펌프의 내구성 강화구조 {The reinforceing internal structure of a vein pump}Reinforced internal structure of a vein pump

본 발명은 베인펌프의 내구성 강화구조에 대한 것으로서, 더 상세하게는 고속회전시 로터와 베인의 갭(Gab)에 의한 베인의 절곡현상을 방지하여 성능저하를 방지하도록 된 베인펌프의 내구성 강화구조에 관한 것이다.The present invention relates to a durable reinforcing structure of the vane pump, and more particularly, to the durability reinforcing structure of the vane pump to prevent bending of the vanes due to the gap between the rotor and the vane at high speed rotation to prevent performance degradation. It is about.

일반적으로 베인펌프는 도 1에 도시된 바와 같이 원형의 개구된 수용홀과 그 측면으로 유출·배출구를 형성한 하우징(1)과, 이 하우징(1)의 수용홀에 편심되게 장착된 회전축(2), 이 회전축(2)의 스플라인(2a)에 회전가능하게 장착되면서 서로 대향되는 위치에 결합홈(3a)을 형성한 로터(3), 이 로터(3)의 결합홈(3a)에 삽입되어 방사상으로 증·감되는 베인(4,4') 및 베인(4,4')이 삽입된 로터(3)를 구비한 회전축(2)이 노출되도록 하우징(1)과 밀봉되는 커버(6)로 구성된다.In general, the vane pump includes a housing 1 having a circular opening receiving hole and a discharge / outlet port at its side as shown in FIG. 1, and a rotating shaft 2 mounted eccentrically in the receiving hole of the housing 1. ), A rotor (3) rotatably mounted on the spline (2a) of the rotary shaft (2) and forming a coupling groove (3a) in a position opposite to each other, and inserted into the coupling groove (3a) of the rotor (3) With a cover 6 sealed with the housing 1 so that the rotating shaft 2 with the vanes 4, 4 'radially increasing and decreasing and the rotor 3 with the vanes 4, 4' inserted therein are exposed. It is composed.

여기서, 상기 베인(4,4')은 로터(3)의 강도유지를 위해 씰링부재(5,5')를 매개로 결합홈(3a)에 삽입되어 진다.Here, the vanes (4, 4 ') is inserted into the coupling groove (3a) via the sealing member (5, 5') to maintain the strength of the rotor (3).

그리고, 상기 회전축(2)과 결합된 로터(3)는 도시되어 있지 않지만, 하우징(1)의 수용홀에 편심되게 장착되어 이 수용홀을 서로 면적이 다른 2부분으로 양분시키게 된다.The rotor 3 coupled to the rotation shaft 2 is not shown, but is mounted eccentrically in the receiving hole of the housing 1 to divide the receiving hole into two parts having different areas from each other.

이와 같은 베인펌프는 동력을 전달받은 회전축(2)에 의해 로터(3)가 하우징(1)의 수용홀내에서 시계방향으로 고속 회전하게 되면, 이 로터(3)의 강한 원심력에 의해 베인(4,4')이 서로 반대방향으로 슬라이딩 되면서 하우징(1)의 수용홀내면쪽으로 이동되므로, 이에 따라 로터(3)의 회전에 따른 베인(4,4')의 위치에 따라 진공을 형성하여 유입구로부터 유입된 오일을 배출구쪽으로 유출시켜 주게 된다.The vane pump is a vane (4,) by the strong centrifugal force of the rotor (3) when the rotor (3) rotates at high speed clockwise in the receiving hole of the housing (1) by the rotary shaft (2) received power 4 ') is moved toward the inner surface of the receiving hole of the housing 1 while sliding in the opposite direction, thereby forming a vacuum according to the position of the vanes 4 and 4' according to the rotation of the rotor 3 to inflow from the inlet. Drained oil to the outlet.

그러나, 상기 베인(4,4')의 두께(d)는 로터(3)의 회전에 따라 방사상으로 작용하는 원심력에 의해 결합홈(3a)내에서 증·감 이동되도록 결합홈(3a)의 폭(D)보다 상대적으로 작게되어, 유입된 오일내에서 고속회전되는 베인(4,4')이 결합홈(3a)내에서 이루는 갭(Gab)에 의해 진동되어 지고, 이로인해 결합홈(3a)의 끝부위에 반복 접촉되는 베인(4,4')부위를 중심으로 절곡이나 변형되어 성능의 저하를 가져오게 되는 문제가 있게 된다.However, the thickness d of the vanes 4 and 4 'is the width of the coupling groove 3a so that the vanes 4 and 4' are moved up and down in the coupling groove 3a by the centrifugal force acting radially as the rotor 3 rotates. The vanes 4 and 4 ', which are relatively smaller than (D) and rotated at high speed in the oil introduced therein, are vibrated by the gap Gab formed in the coupling groove 3a, and thus, the coupling groove 3a. The vanes (4,4 ') that are repeatedly in contact with the end portion of the bent or deformed around the problem that causes a problem of degradation.

이러한 문제는 로터(3)의 결합홈(3a)의 폭(D)과 이에 삽입되는 베인(4,4')의 두께(d)의 차이로 인한 갭을 줄이거나 또는 베인(4,4')의 길이를 증가시켜 해소할 수 있지만, 갭의 축소는 베인(4,4')의 습동에 악 영향을 주게되고 베인(4,4')의 길이 증가는 회전축(2)의 공간확보로 인해 구조상 불가능하게 되는 문제가 있게 된다.This problem reduces the gap due to the difference between the width D of the coupling groove 3a of the rotor 3 and the thickness d of the vanes 4 and 4 'inserted therein or the vanes 4 and 4'. It can be solved by increasing the length of the gap, but shrinking the gap adversely affects the sliding of the vanes (4,4 '), and the increase in the length of the vanes (4,4') is due to the construction of the space of the rotating shaft (2). There is a problem that becomes impossible.

따라서 본 발명은 상기와 같은 종래의 문제점을 감안하여 이를 해결 보완하고자 발명한 것으로서, 베인의 길이를 증대하면서도 내구성을 강화시켜 베인펌프의 성능을 향상시키는데 있게 된다.Therefore, the present invention has been invented to solve the above-mentioned problems in view of the above-described conventional problems, thereby increasing durability of the vane and improving durability of the vane pump.

이를 위한 특징적인 실시 수단은 상기 회전축에 소정 길이로 안착홈을 형성시켜 이 안착홈에 삽입되는 씰링부재와 베인이 각각 "??"자 형상으로 단차진 절곡단과 돌출된 돌출단을 매개로 결합되어 지도록 구성된다.Characteristic implementation means for this is to form a seating groove with a predetermined length in the rotating shaft is coupled to the sealing member and the vane inserted into the seating grooves through the stepped bent end and protruding end in the shape of "??" It is configured to lose.

이하 본 발명의 실시예에 따른 구성 및 작용을 첨부 도면에 따라 상세히 설명한다.Hereinafter, the configuration and operation according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 베인펌프의 분해 결합도를 도시한 것인바, 원형의 개구된 수용홀과 그 측면으로 유출·배출구를 형성한 하우징(1)과, 이 하우징(1)의 수용홀에 편심되게 장착된 회전축(2), 이 회전축(2)의 스플라인(2a)에 회전가능하게 장착되면서 서로 대향되는 위치에 결합홈(3a)을 형성한 로터(3), 이 로터(3)의 결합홈(3a)에 내구성 향상을 위해 삽입되는 씰링부재(5,5'), 이 씰링부재(5,5')에 이어 삽입되어 방사상으로 증·감되는 베인(4,4') 및 베인(4,4')이 삽입된 로터(3)를 구비한 회전축(2)이 노출되도록 하우징(1)과 밀봉되는 커버(6)로 구성된다.Figure 2 shows an exploded coupling of the vane pump of the present invention, a housing (1) formed with a circular opening receiving hole and an outlet / outlet on its side, and an eccentricity in the receiving hole of the housing (1) Rotor 3, which is mounted so as to be rotatably mounted on the spline 2a of the rotary shaft 2, and has a coupling groove 3a formed at a position opposite to each other, the coupling groove of the rotor 3 Sealing members 5 and 5 'inserted in 3a to improve durability, and vanes 4 and 4' and vanes 4 and 4 inserted after the sealing members 5 and 5 'and radially increased and decreased. It consists of a cover 6 which is sealed with the housing 1 so that the rotating shaft 2 with the rotor 3 with 4 ') inserted therein is exposed.

여기서, 상기 회전축(2)의 스프라인(2a)에는 결합홈(3a)과 일치되는 지점에 소정 길이로 안착홈(2a')이 형성됨과 더불어, 이 안착홈(2a')에 삽입되는 씰링부재(5,5')에는 "??"자 형상으로 단차진 절곡단(5a,5a')을 형성되고, 이 씰링부재(5,5')의 절곡단(5a,5a')에 결합되는 베인(4,4')에는 돌출된 돌출단(4a,4a')이 형성되어 진다.Here, in the spline (2a) of the rotating shaft (2) is formed a seating groove (2a ') with a predetermined length at a point coinciding with the coupling groove (3a), and the sealing member inserted into the seating groove (2a') (5,5 ') is formed with stepped bent ends (5a, 5a') having a "??" shape, and vanes coupled to bent ends (5a, 5a ') of the sealing members (5, 5'). Protruding end portions 4a and 4a 'are formed at 4 and 4'.

그리고, 상기 회전축(2)과 결합된 로터(3)는 도시되어 있지 않지만, 하우징(1)의 수용홀에 편심되게 장착되어 이 수용홀을 서로 면적이 다른 2부분으로 양분시키게 된다.The rotor 3 coupled to the rotation shaft 2 is not shown, but is mounted eccentrically in the receiving hole of the housing 1 to divide the receiving hole into two parts having different areas from each other.

이와 같은 베인펌프는 종래의 경우와 같이 하우징(1)의 수용홀내에서 시계방향으로 고속 회전하는 로터(3)의 강한 원심력에 의해 베인(4,4')이 서로 반대방향으로 슬라이딩 되면서 그 위치에 따라 진공을 형성하여 유입구로부터 유입된 오일을 배출구쪽으로 유출시켜 주게 된다.Such vane pump is positioned in the vanes 4 and 4 'while the vanes 4 and 4' slide in opposite directions by the strong centrifugal force of the rotor 3 which rotates at a high speed clockwise in the housing hole of the housing 1 as in the conventional case. As a result, a vacuum is formed to allow oil introduced from the inlet to flow out to the outlet.

또한, 상기 회전축(2)의 안착홈(2a')과 씰링부재(5a,5a')의 절곡단(5a,5a') 및 베인(4,4')의 돌출단(4a,4a')을 매개로 서로 결합되어 베인(4,4')과 로터(3)의 결합홈(3a)에 위해 발생된 갭(Gab)에 의한 진동발생이 방지되는 한편, 베인(4,4')의 길이가 돌출단(4a,4a')의 길이 많큼 증대되어 원심력에 의한 베인(4,4')의 방사상 슬라이딩의 길이 증대가 이루어져 베인펌프의 성능향상을 가져오게 된다.In addition, the bending grooves 5a and 5a 'of the seating grooves 2a' of the rotary shaft 2 and the sealing members 5a and 5a 'and the protruding ends 4a and 4a' of the vanes 4 and 4 ' Are coupled to each other to prevent the occurrence of vibration by the gap (Gab) generated for the coupling groove (3a) of the vanes (4, 4 ') and the rotor (3), while the length of the vanes (4, 4') As the lengths of the protruding ends 4a and 4a 'are increased, the length of the radial sliding of the vanes 4 and 4' is increased due to the centrifugal force, thereby improving the performance of the vane pump.

위에서 상세히 설명한 바와 같은 본 발명은, 단차진 형상을 매개로 서로 결합되어 베인의 길이가 증대되면서도 고속회전에 따른 내구성도 강화시켜 베인펌프의 성능이 향상되는 효과가 있게된다.As described in detail above, the present invention is coupled to each other through a stepped shape to increase the durability of the vane pump while increasing the vane length, thereby improving the performance of the vane pump.

본 발명의 보호범위는 이하 청구될 청구범위를 통해 상세히 언급되어지나, 청구범위에 언급되지 않을 경우라도 동 분야에서 통상의 지식을 가진자에 의해 변형이나 변경될 수 있는 사항들은 본 발명의 또다른 실시예로 한정되어짐은 물론이다.The protection scope of the present invention will be described in detail through the claims to be described below, but the matters that can be modified or changed by those skilled in the art even if the claims are not mentioned in another embodiment of the present invention Of course, it is limited to the example.
