Description

공기압축전용 베인펌프Air Compression Vane Pump

본 발명은 공기압축전용 베인펌프(vane pump)의 케이싱내부에 장착된 로터(Rotor)회전축과 베인(Vane)고정축의 축간거리를 달리하여 베인을 별개의 고정축에서 회전토록하므로서, 베인과 케이싱의 접동부마모현상을 일소하고 공기의 압축효율을 배가하며 사용수명을 일층개선한 공기압축전용 베인펌프에 관한 것이다.According to the present invention, the vanes are rotated on separate fixed shafts by varying the distance between the rotor rotating shaft and the vane fixed shaft mounted inside the casing of the vane pump for exclusive use of air compression. The present invention relates to a vane pump for exclusive use of air compression, which eliminates sliding wear, doubles the compression efficiency of air, and improves service life.

일반적으로 대기압 이하의 저압기체를 빨아들이고 압축해서 대기 중으로 방출함으로써, 용기 내의 진공도를 높이는 진공펌프(vacuum pump)형식의 일종인 공기압축전용 베인펌프(vane pump)는 하기와 같은 다수의 문제점이 있었다.In general, a vane pump dedicated to air compression, which is a type of vacuum pump that increases the degree of vacuum in a container by sucking, compressing low pressure gas below atmospheric pressure, and releasing it into the atmosphere, has a number of problems as follows. .

즉, 모터의 회전축과 연결된 로터의 회전에 따라 상기 로터의 몸체에 내입된 베인은 원심력에 의해 반지름 방향으로 출입하며 기체를 압축하는 과정하에 상기 로터몸체에 내입된 베인은 원심력에 의존하여 출입하므로 케이싱접동부에 과도한 마찰력을 가하여 베인단부와 케이싱내부의 마모를 발생케되고 이로 인해 진공도저하와 잦은 고장으로 그 사용수명이 현저히 떨어지는 등의 심각한 문제점이 있었다.That is, the vane embedded in the body of the rotor according to the rotation of the rotor connected to the rotation axis of the motor enters and exits in the radial direction by the centrifugal force. Excessive frictional force is applied to the sliding part, which causes wear of the vane end and the casing, which causes serious problems such as a significant drop in the service life due to vacuum dropping and frequent failures.

본 발명은 상기에서 설명한 바와 같은 종래의 공기압축전용 베인펌프가 갖는 문제점을 해결하기 위해 안출한 것으로, 다수의 베인을 로터몸체에 내입하지 않고 독립적으로 분리하여 고정축에서 항상 일정한 간격을 유지하며 회전하도록 하므로서 케이싱접동부와의 마찰현상을 일소하여 최대의 압축효율과 사용수명을 갖는 공기압축전용 베인펌푸를 제공코져 하는 것이다.The present invention has been made in order to solve the problems of the conventional air compression vane pump as described above, the plurality of vanes are not separated into the rotor body to be separated independently and always maintain a constant interval on the fixed shaft rotation It is to provide vane pump for exclusive use of air compression with maximum compression efficiency and service life by eliminating friction phenomenon with casing sliding part.

상기와 같이 구성된 본 발명은 모터(71)의 구동에 의하여 일련의 공기압축과정을 수행하게 되는 것으로, 상기 모터(71)의 회전축(72)에 결합된 로터(21)가 회전하게 되고, 상기 회전축(72)과 축간거리(h)만큼 떨어진 고정축(14)에 결합된 베인(11)은 상기 로터(21)의 절개부(23)에 각각 내입되어 있으므로 로터(21)와 같이 동일방향으로 회전한다. 이때 베인(11)은 커버(51)의 고정구(56)에 지지된 고정축(14)을 중심으로 고정축(14)상에서 회전되게 구성되어 있으므로 케이싱(41)내부 압축실(42)의 접동부(A,B)와 베인(11)단부가 원심력으로 인한 마찰을 일으키지 않고 일정간격을 유지하면서 회전하는 것이며, 제3도, 제4도에 도시된 바와 같이 수개의 베인(11)은 로터(21)의 절개부(23)내에서 회전위치에 따라 변하는 유동각(θ)운동을 간섭하지 않은 넓이로 형성되어진 것이며, 베인(11)과 절개부(23)사이는 부시(15)에 의해 기밀성을 유지하게 된다. 상기 반원형 부시(15)는 베인(11)의 유동각(θ)운동에 따라 절개부(23)내에서 자유롭게 원호운동을 하면서도 충분한 기밀성을 유지할 수 있는 재질로 된 것이다.The present invention configured as described above is to perform a series of air compression process by the drive of the motor 71, the rotor 21 coupled to the rotary shaft 72 of the motor 71 is rotated, the rotary shaft The vanes 11 coupled to the fixed shaft 14 apart from the 72 and the distance between the shaft h are embedded in the cutouts 23 of the rotor 21, so that the vanes 11 rotate in the same direction as the rotor 21. do. At this time, since the vane 11 is configured to rotate on the fixed shaft 14 about the fixed shaft 14 supported by the fastener 56 of the cover 51, the sliding part of the compression chamber 42 inside the casing 41. (A, B) and the vane 11 end is rotated while maintaining a constant interval without causing friction due to centrifugal force, several vanes 11 as shown in Figs. It is formed to the area that does not interfere with the flow angle (θ) movement that changes depending on the rotational position in the cutout portion 23 of the), the airtightness between the vanes 11 and the cutout 23 by the bush (15) Will be maintained. The semi-circular bush 15 is made of a material capable of maintaining sufficient airtightness while freely arcing in the cutout 23 according to the flow angle θ of the vane 11.

상기 베인(11)의 유동각(θ)운동은 회정축(72)과 고정축(14)의 축간거리(h) 차이로 인해 발생하는 것이며, 결합링(12)에 내설된 베어링(13)에 의해 각각의 베인(11)은 커버(51)의 고정구(56)에 지지된 고정축(14)을 중심으로 원활한 회전운동을 하는 것이다.The flow angle (θ) of the vane 11 is caused by the difference between the shaft distance (h) between the gray shaft (72) and the fixed shaft (14), the bearing 13 in the coupling ring 12 Each vane 11 is a smooth rotational movement around the fixed shaft 14 supported by the fastener 56 of the cover 51.

상기와 같이 로터(21)가 고속회전을 할 시 중공부(24)와 절개부(23)로 인해 분할된 로터(21)단부는 강한 원심력의 작용에 의해 미소한 확개현상이 발생케 되는데, 제2도에 도시된 바와 같이 커버(51)내측에 형성된 편심홈(53)에 고정링(61)을 내설하여 상기 고정링(61) 내경으로 로터(21)단부의 단턱(22)이 삽지되도록 하므로서 상기 로터(21)의 확개현상을 방지한 것이다.As described above, when the rotor 21 rotates at a high speed, the end portion of the rotor 21 divided by the hollow part 24 and the incision part 23 may have a slight expansion phenomenon due to the action of a strong centrifugal force. As shown in FIG. 2, the fixing ring 61 is installed in the eccentric groove 53 formed inside the cover 51 so that the stepped end 22 of the end of the rotor 21 is inserted into the fixing ring 61. The expansion phenomenon of the rotor 21 is prevented.

그리고, 고정커버(31)의 편심턱(33)과 커버(51)에 형성돈 편심턱(54)은 케이싱(41)을 체결할 시 압축실(42)내의 기밀성을 보장하는 것이다.In addition, the eccentric jaw 54 formed on the eccentric jaw 33 and the cover 51 of the fixing cover 31 is to ensure the airtightness in the compression chamber 42 when the casing 41 is fastened.

이상에서 상세히 살펴본 바와 같이 본 발명은 기존의 베인펌프(1)의 구성을 획기적으로 개선한 것으로서, 로터(21)에 내입되는 수개의 베인(11)을 각각 독립적으로 분리구성하여 별도로 마련된 고정축(14)을 중심으로 회전시킴으로서 압축실(42)내의 접동부(A,B)와 베인(11)단부의 마모현상을 일소하여 압축효율을 극대화하며 사용수명을 가일층 연장시킨 매우 유용한 발명이다.As described in detail above, the present invention is a remarkable improvement in the configuration of the existing vane pump 1, and fixed vanes are separately provided by separately separating several vanes 11 into the rotor 21. By rotating around 14) it is a very useful invention that maximizes the compression efficiency and further extends the service life by eliminating the wear phenomenon of the sliding portion (A, B) and the vane 11 end in the compression chamber (42).
