본 발명은 로터리 베인 펌프에 관한 것으로, 더욱 상세하게는 로터리 베인 펌프에서, 펌프의 저속·저온시 로타축 내에 위치한 베인의 비출운동을 원활히하고, 베인과 링의 실링 성능을 향상시키기 위하여 펌프커버와 일체로 된 축의 외경에 환형 스프링을 장착하여 로타축 내에 위치한 베인에 반경 방향의 힘을 가함으로써 저속·저온시 베인의 출입운동을 양호하게 하여 펌프의 펌핑능력을 향상시키고, 베인의 운동을 규제하는 조건인 링과 로타축의 반경 허용치를 크게 하여 펌프의 조립 및 가공성을 향상시키고, 베인과 링의 접촉력을 향상시켜서 베인과 링간의 실링 성능을 향상시키고자 하는데 있는 것이다.The present invention relates to a rotary vane pump, and more particularly, in a rotary vane pump, a pump cover and a pump cover for smoothing the vane movement in the rota shaft at low and low temperatures and improving the sealing performance of the vanes and rings. The annular spring is mounted on the outer diameter of the integrated shaft to apply the radial force to the vanes located in the rotatable shaft to improve the pumping ability of the vanes at low and low temperatures, thereby improving the pumping capacity of the vanes and regulating the movement of the vanes. It is intended to improve the sealing performance between vanes and rings by improving the assembly and workability of the pump by increasing the radius allowance of the ring and the rota shaft, which are the conditions, and the contact force between the vanes and the rings.

종래의 로터리 베인 펌프는 제6도 및 제7도에 나타낸바와 같이 하우징(100), 펌프 커버(101), 로타축(102), 베인(103), 링(104)으로 이루어져, 펌프 작동시, 베인(103)은 펌프 커버(101)와 일체로 된 축(105)에 결합된 부시 베어링(106)과 펌프 하우징(100)에 결합된 링(104) 사이의 로타축(102)내에서 왕복 및 회전운동을하여 펌핑하는 구조를 취하고 있다.Conventional rotary vane pump is composed of a housing 100, a pump cover 101, a rotatable shaft 102, a vane 103, a ring 104, as shown in Figures 6 and 7, The vanes 103 reciprocate within the rotatable shaft 102 between the bush bearing 106 coupled to the shaft 105 integral with the pump cover 101 and the ring 104 coupled to the pump housing 100. It takes a structure to pump by rotating motion.

이러한 종래의 로터리 베인 펌프는, 서로 다른 중심점을 갖는 편심된 로타축(102)과 링(104)의 회전운동에 의해서 펌핑작용을 하게 된다. 이때, 로타축(102)내에 위치한 베인(103)은 펌프 커버(101)와 일체로된 축(105)에 결합된 부시 베어링(106)의 외주면을 베인 캡(107)은 펌프 하우징(100)에 결합된 링(104)의 내부면을 따라서 로터축(102)내에서 왕복 및 회전운동을 한다.This conventional rotary vane pump is pumped by the rotational movement of the eccentric rota shaft 102 and the ring 104 having different center points. At this time, the vane 103 located in the rotatable shaft 102 has the outer circumferential surface of the bush bearing 106 coupled to the shaft 105 integral with the pump cover 101, and the vane cap 107 is disposed at the pump housing 100. Reciprocating and rotational movement in the rotor shaft 102 along the inner surface of the coupled ring 104.

베인(103) 및 베인 캡(107)의 반경 방향의 치수는 링(104)의 반경과 부시 베어링(106)의 반경 치에 크게 의존함으로 운동 상태의 제한과 펌프의 가공 및 조립이 어려워지는 문제점이 있다.The radial dimensions of the vanes 103 and vane caps 107 largely depend on the radius of the ring 104 and the radius of the bush bearing 106, thereby limiting the state of motion and making machining and assembly of the pump difficult. have.

즉, 베인(103), 베인 캡(107), 부시 베어링(106)의 3개의 단품이 정확한 치수로 가공이 되지 않으면 조립시 심각한 문제가 발생할 수 있고, 베인(103) 및 베인 캡(107)이 링(104)과 상대 운동을 하므로 접촉 부분에서 마모가 발생하고, 이 마모 량이 펌프의 성능에 큰 영향을 미친다.That is, if three pieces of the vane 103, the vane cap 107, the bush bearing 106 is not processed to the correct dimensions can cause serious problems during assembly, the vane 103 and the vane cap 107 is Because of the relative motion with the ring 104, wear occurs at the contact, and this amount of wear greatly affects the performance of the pump.

따라서 베인(103) 및 베인 캡(107)에 마모가 발생하여도 초기 상태에서는 베인 캡(107)이 마모 량이 일정량을 보상할 수 있지만, 점차적으로 마모 량이 커짐에 따라서 베인(103) 및 베인 캡(107)의 보상한계 치를 넘게 되면 링(104)과 베인 캡(107)간의 접촉력이 떨어져서 펌프의 실링 성능에 큰 문제점이 발생하여 펌프의 성능을 발휘하지 못하였으며, 반대로 최초 펌프 조립시 베인(103) 및 캡(107)의 치수를 크게 하면 조립이 곤란하고 펌프 작동 상에 많은 문제점을 안고 있었다.Therefore, even if abrasion occurs in the vane 103 and the vane cap 107, in the initial state, the vane cap 107 can compensate for a certain amount of wear, but as the amount of wear gradually increases, the vane 103 and the vane cap ( If the compensation limit of 107 is exceeded, the contact force between the ring 104 and the vane cap 107 drops, causing a large problem in the sealing performance of the pump. And when the size of the cap 107 is enlarged, assembly is difficult and there are many problems in pump operation.

따라서 본 발명에서는 비평형형 로터리 베인 펌프에서, 베인을 반경방향으로 알 수 있는 환형 스프링을 장착하여 저속·저온시 베인의 출입성능을 양호하게 하여 펌핑성능을 향상시키고, 베인 및 베인 캡의 마모량 보상을 위해 링과 로타축의 반경 허용치를 크게 하여 펌프의 조립 및 가공성을 향상시키고, 베인과 링의 접촉력을 향상시켜서 베인과 링간의 실링성능을 향상시키도록 함에 있는 것이다.Therefore, in the present invention, in the non-equilibrium rotary vane pump, the annular spring which knows the vanes radially is installed to improve the pumping performance by improving the vaning performance at low and low temperatures, and to compensate the wear of the vanes and vane caps. In order to improve the assembling and workability of the pump by increasing the radius tolerance of the ring and the rota shaft, and to improve the sealing performance between the vane and the ring by improving the contact force between the vane and the ring.

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.

제1도 내지 제3도에 나타낸 바와 같이 본 발명은 펌프 하우징(1)과 베인(2), 로타축(3), 환형 스프링(4)과 흡입,토출포트(51,52)를 갖고 있는 펌프 커버(5)가 구비되고, 로타축(3) 내에서 왕복 및 회전운동을 하는 베인(2)이 제4도같이 구성된 환형 스프링(4)에 의해서 반경 방향의 힘을 받아서 펌프 하우징(1)에 결합된 링(6)과 베인 캡(7)간의 접촉력을 향상시키는 구조로 구성되고 있다.As shown in Figs. 1 to 3, the present invention is a pump having a pump housing (1) and a vane (2), a rotatable shaft (3), an annular spring (4) and suction and discharge ports (51, 52). The vane 2, which is provided with a cover 5 and reciprocates and rotates in the rotatable shaft 3, receives radial force by the annular spring 4 configured as shown in FIG. It is composed of a structure for improving the contact force between the combined ring 6 and the vane cap (7).

이러한 구성으로 된 본 발명은 펌프 작동시, 일정 편심량을 갖고 회전운동을 하는 로타축(3)내의 베인(2)과 펌프 하우징(1)에 고정된 링(6)의 상대 운동에 의해서 펌핑작용이 일어난다.According to the present invention, the pumping action is controlled by the relative movement of the vane 2 in the rota shaft 3 and the ring 6 fixed to the pump housing 1 with a certain amount of eccentricity. Happens.

이때 로타축(3)내에 위치한 베인(2)은 최초 펌프 구동시 로타축(3)내에 장착한 환형 스프링(4)의 탄성력에 의해서 링(6)의 내주면에 접촉하고 로타축(3)의 구동에 의해서 펌핑작용을 하게 된다.At this time, the vane 2 located in the rotatable shaft 3 contacts the inner circumferential surface of the ring 6 by the elastic force of the annular spring 4 mounted in the rotatable shaft 3 when the pump is first driven, and drives the rotatable shaft 3. It is pumped by.

이처럼 로타축(3)내에 환형 스프링(4)을 장착하여 베인(2)에 반경방향의 힘을 부여함으로써, 종래의 펌프에서 베인 및 베인 캡의 조립 및 운동성능을 제한하는 조건인 링과 부시 베어링의 반경치에 대한 영향을 적게 받음으로써 펌프의 조립성 및 가공성이 크게 향상되는 이점이 있다.Thus, by mounting the annular spring (4) in the rotatable shaft (3) to give the vane (2) a radial force, the ring and bush bearing, which is a condition that limits the assembly and movement performance of the vane and vane cap in the conventional pump By being less affected by the radius of the has the advantage that the assembly and workability of the pump is greatly improved.

최초 펌프 구동시 베인(2)에 환형 스프링(4)의 탄성력을 이용한 기계적인 힘을 부여하여 링(6)과 베인 캡(7)간의 접촉력을 유지하여 저온·저속시 펌프 흡입 성능의 향상 및 내부 누설을 최소화 할 수 있게 된다.When the pump is driven for the first time, the mechanical force using the elastic force of the annular spring 4 is applied to the vane 2 to maintain the contact force between the ring 6 and the vane cap 7 to improve the pump suction performance at low and low speeds and Leakage can be minimized.

따라서 베인(2) 및 베인 캡(7)에 마찰에 의한 마모가 발생하여도 환형스프링(4)의 탄성 영역 내에서는 보상을 할 수 있으므로 펌프의 내구성이 크게 향상되는 이점이 있게 된다.Therefore, even if abrasion due to friction occurs in the vane 2 and the vane cap 7, compensation can be made in the elastic region of the annular spring 4, so that the durability of the pump is greatly improved.

이상에서와 같이 본 발명은 로터리 베인 펌프에서, 베인을 반경 방향으로 밀 수 있는 환형 스프링을 장착하여 저속·저온시 베인의 출입성능을 양호하게 하여 펌핑성능을 향상시키고, 베인 및 베인 캡의 마모량 보상을 위해 링과 로타축의 반경 허용치를 크게 하여 펌프의 조립 및 가공성을 향상시키고, 베인과 링의 접촉력을 향상시켜서 베인과 링간의 실링성능이 향상되는 장점이 있게 된다.As described above, the present invention is equipped with an annular spring that can push the vanes radially in the rotary vane pump to improve the pumping performance by improving the outgoing performance of the vanes at low and low temperatures, compensation of the wear of the vanes and vane cap In order to improve the assembling and workability of the pump by increasing the radius allowance of the ring and the rota shaft, and to improve the contact force between the vane and the ring, the sealing performance between the vane and the ring is improved.
