본 발명은 베인 펌프에 관한 것으로, 더욱 상세하게는 로터리 베인 펌프에 있어서, 로타축의 회전운동을 원활히 하고 펌프 하우징 및 커버의 과도한 마모 및 이상 소음을 저감시키도록 한 것이다.The present invention relates to a vane pump, and more particularly, to a rotary vane pump, which facilitates the rotational movement of the rotatable shaft and reduces excessive wear and abnormal noise of the pump housing and the cover.

또한 본 발명에서는 펌프의 조립 공차 값을 크게 하기 위하여, 펌프부하의 변화에 따라서 압력판이 축방향으로 움직일 수 있도록 하여 로타축의 작동을 원활히 하고, 로타축과 펌프 하우징 및 커버에서 발생하는 과도한 마모 방지 및 이상 소음을 저감시켜 펌프의 내구성 및 성능을 향상시킴은 물론, 펌프의 가공성을 향상시킬 수 있는 로터리 베인 펌프를 제공함에 있는 것이다.In addition, in the present invention, in order to increase the assembly tolerance value of the pump, the pressure plate is able to move in the axial direction in accordance with the change of the pump load to facilitate the operation of the rotatable shaft, and to prevent excessive wear occurring in the rotatable shaft and the pump housing and cover and It is to provide a rotary vane pump that can reduce the abnormal noise to improve the durability and performance of the pump, as well as improve the processability of the pump.

종래에는 제6도 및 제7도에 나타낸 바와 같이 펌프 하우징(100), 커버(110), 로타축(102), 베인(103), 링(104)으로 이루어져 펌프 작동시 로타축이 펌프 커버(101) 및 펌프 하우징(100) 사이에서 직접적인 회전운동을 하도록 구성되고, 로타축(102)이 펌프 하우징(100) 및 커버(101)의 크기(폭)에 크게 의존하는 구조를 취하고 있다.Conventionally, as shown in FIGS. 6 and 7, the pump housing 100, the cover 110, the rotatable shaft 102, the vanes 103, and the ring 104 are configured to operate the rotatable shaft when the pump is operated. It is configured to make a direct rotational motion between the 101 and the pump housing 100, and the rotatable shaft 102 has a structure that largely depends on the size (width) of the pump housing 100 and the cover (101).

이러한 구성으로된 종래의 로터리 베인 펌프는, 서로 다른 중심점을 갖는 편심된 로타축(102)과 링(104)의 회전운동에 의해서 펌핑작용을 하게 된다. 이때 로타축(102)은 펌프 하우징(100) 및 커버(101) 사이에서 밀착된 상태로 운동을 하게 된다.The conventional rotary vane pump having such a configuration is pumped by the rotational movement of the eccentric rota shaft 102 and the ring 104 having different center points. In this case, the rotatable shaft 102 moves in close contact between the pump housing 100 and the cover 101.

구동시 로타축(102)이 펌프 커버 및 하우징(100) 사이에서 회전운동을 하기 때문에 로타축(102)의 양측면에서 마찰이 발생하고, 이 마찰에 인해 로타축(102)과 펌프 하우징(100) 및 커버(101)에서 과도한 마모 및 이상 소음이 발생하여 펌프의 수명 및 성능에 악영향을 미치게 되는 문제점이 있었다.Since the rotatable shaft 102 rotates between the pump cover and the housing 100 during driving, friction occurs on both sides of the rotatable shaft 102, and the friction causes the rotatable shaft 102 and the pump housing 100 to rotate. And excessive wear and abnormal noise occurs in the cover 101 has a problem that adversely affect the life and performance of the pump.

더욱이, 로타축의 원활한 회전운동을 위해서 로타축의 양 측면에 일정한 값의 틈새를 부여해야 하므로 가공이 어렵다.Moreover, machining is difficult because a certain value of clearance must be provided on both sides of the rotatable shaft for smooth rotation of the rotatable shaft.

또한 펌프의 부하가 커지면 내부 누설량이 크게 증가하는 문제점이 있다.In addition, when the load of the pump increases, there is a problem that the internal leakage amount increases significantly.

본 발명은 상기와 같은 종래의 재결점을 해소하기 위해, 로터의 베인 펌프에서 발생되는 토출압유를 압력판으로 도입하여 펌프 하우징 및 커버의 마모 및 소음을 절감시킬 수 있게 하고, 로타축의 회전운동을 원활히하여 펌프의 내구성 및 성능 향상을 도모할 수 있는 로터리 베인 펌프를 제공함에 그 목적이 있는 것이다.The present invention is introduced to the pressure plate to the discharge pressure oil generated in the vane pump of the rotor in order to eliminate the above-mentioned re-defects as described above, it is possible to reduce the wear and noise of the pump housing and cover, and smoothly rotate the rotation of the rota shaft The purpose is to provide a rotary vane pump that can improve the durability and performance of the pump.

이하, 본 발명을 첨부된 예시 도면을 참고하여 보다 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

본 발명은 제1도 내지 제3도와 같이, 펌프 하우징(1), 베인(6), 로타축(3)이 구비되는 로터리 베인 펌프에 있어서, 토출유를 압력판(4)으로 도입할 수 있는 유로(21)와 유로(21)내의 오리피스(22) 및 흡입/토출포트(23,24)를 갖는 펌프 커버(2)와, 2개의 압력판(4a,4b)을 연통공이 구비되는 링(5), 및 원형의 그루브(42)를 갖는 압력판(4)으로 되는 구성으로 이루어지고 있다.In the rotary vane pump provided with the pump housing 1, the vane 6, and the rotatable shaft 3, as shown in FIGS. 1 to 3, the flow path through which the discharge oil can be introduced into the pressure plate 4 is provided. A pump cover 2 having an orifice 22 and suction / discharge ports 23 and 24 in the flow passage 21 and two pressure plates 4a and 4b; And a pressure plate 4 having a circular groove 42.

이러한 구성으로 된 본 발명의 작용 효과를 설명하면 다음과 같다.Referring to the operation and effect of the present invention having such a configuration as follows.

펌프 작동시 일정 편심량을 갖고 회전 운동하는 로터축(3)과 하우징(1)에 고정된 링(5)의 상대 운동에 의해 펌핑작용이 일어난다. 이때 토출포트(24)에서 토출되는 압유의 일부를 펌프 커버의 유로내에 설치한 오리피스를 통해서 고압의 토출유를 감압시킨 후, 로타축의 양측면에 위치한 원형의 그루브(42)가 구비되는 2개의 압력판(4a,4b)에 토출압력의 변화에 따라서 변동하는 일정 압력의 압유를 공급함으로써, 로타축의 축방향으로 압력판(4)이 움직이게 된다.The pumping action is caused by the relative movement of the rotor shaft 3 and the ring 5 fixed to the housing 1 with a certain amount of eccentricity during rotation of the pump. At this time, after reducing the high pressure discharge oil through an orifice in which a part of the pressure oil discharged from the discharge port 24 is provided in the flow path of the pump cover, two pressure plates provided with circular grooves 42 located on both sides of the rota shaft ( The pressure plate 4 is moved in the axial direction of the rotatable shaft by supplying 4a, 4b with the pressure oil having a constant pressure which changes in accordance with the change of the discharge pressure.

로타축(3)과 압력판(4) 및 로타 사이의 틈새를 펌프 부하의 변동에 따라서 변화를 줌으로써, 로타축(3) 및 베인(6)이 운동시 받는 펌프 부하의 영향을 저감시켜 로타축(3) 및 베인(6)의 운동을 원활하게 함으로써, 펌프의 성능이 향상되게 된다.By changing the clearance between the rotor shaft 3, the pressure plate 4, and the rotor in accordance with the variation of the pump load, the influence of the pump load that the rotor shaft 3 and the vane 6 are subjected to during movement is reduced. By smoothing the motion of 3) and the vane 6, the performance of the pump is improved.

2개의 압력판(4a,4b)은 펌프 하우징(1) 및 커버(2)와 로타축(3)의 직접적인 운동을 배제하여, 로타축과 펌프 하우징 및 커버의 과도한 마모와 이상 소음을 감소시킬 수 있게 된다.The two pressure plates 4a and 4b eliminate the direct movement of the pump housing 1 and the cover 2 and the rotatable shaft 3 so as to reduce excessive wear and abnormal noise of the rotatable shaft and the pump housing and cover. do.

따라서 로타축(3)에 마모가 발생하여도 일정한 마모치를 보상할 수 있게 되어 펌프의 내구성이 향상되고, 2개의 측판 사이에 위치한 링(5) 및 로타축(3)과 펌프 하우징(1)의 조립 공차값도 종래의 로터리 베인 펌프에 비해서 상대적으로 크게 할 수 있으므로 가공성이 향상되는 이점이 있게 된다.Therefore, even if abrasion occurs in the rotatable shaft 3, it is possible to compensate for a certain wear value, thereby improving the durability of the pump, and the ring 5 and the rotatable shaft 3 and the pump housing 1 located between the two side plates. Since the assembly tolerance value can be made relatively large as compared with the conventional rotary vane pump, there is an advantage that the workability is improved.

이와같이 본 발명에 따른 로터리 베인 펌프는 펌프의 토출측에서 나오는 고압의 압유를 감압시켜 압력판에 공급할 수 있는 유로와 균등한 압력을 부여하는 압력판(4)이 펌프 하우징(1) 및 커버(2)를 로타축(3)과 격리시킴으로써, 펌프 하우징(1) 및 커버(2)에서 발생하는 이상 마모 및 이 마모에 의한 이상 소음이 저감되는 이점이 있다.As described above, in the rotary vane pump according to the present invention, the pressure plate 4 which provides pressure equal to the flow path that can be supplied to the pressure plate by reducing the high pressure pressure oil from the discharge side of the pump rotates the pump housing 1 and the cover 2. By isolation from the shaft 3, there is an advantage that abnormal wear occurring in the pump housing 1 and the cover 2 and abnormal noise caused by the wear are reduced.

또한 2개의 압력판(4a,4b)과 링(5) 및 로타축(3)의 틈새 값을 펌프 부하에 따라 변동시켜 로타축의 회전운동시 펌프 부하의 영향을 감소시킴으로써, 로타축의 운동을 원활히 하고, 펌프 부하가 클 때의 내부 누설량도 감소시킬 수 있게 된다.In addition, the gap values of the two pressure plates 4a and 4b and the ring 5 and the rotatable shaft 3 are varied according to the pump load to reduce the influence of the pump load during the rotational movement of the rotatable shaft, thereby smoothing the rotatable shaft movement. Internal leakage can also be reduced when the pump load is high.

그러므로 로타축에 마모가 발생하여도 일정 한도 내의 마모량을 보상할 수 있게 되어 종래의 로터리 베인 펌프에 비해서 내구성과 성능의 향상 및 가공성이 향상되는 등의 장점이 있다.Therefore, it is possible to compensate for the amount of wear within a certain limit even if wear occurs in the rota shaft, and has advantages such as improved durability, performance, and workability compared to the conventional rotary vane pump.

이상에서와 같이 본 발명은 로터의 베인 펌프에서 발생되는 토출압유를 압력판으로 도입하여 펌프 하우징 및 커버의 마모 및 소음을 절감시키고, 로타축의 회전운동을 원활히 하여 펌프의 내구성 및 성능향상을 도모하게 되는 이점이 있게 된다.As described above, the present invention reduces the wear and noise of the pump housing and cover by introducing the discharge pressure oil generated from the vane pump of the rotor to the pressure plate, and improves the durability and performance of the pump by smoothly rotating the rota shaft. There is an advantage.
