본 고안은 압축기, 펌프, 송풍기로 사용되는 유체압축기에 관한 것으로서, 특히 베인형 유체압축기에 있어서 케이싱을 회전자재토록 설치하여 베인과 케이싱 사이의 미끄럼저항을 저감할 수 있도록 구성된 유체압축기에 관한 것이다.The present invention relates to a fluid compressor used as a compressor, a pump, and a blower, and more particularly, to a fluid compressor configured to reduce sliding resistance between a vane and a casing by installing a casing in a vane type fluid compressor.

일반적으로 베인형 유체압축기는 제1도는 도시된 바와같이 케이싱(1)과, 케이싱(1) 내에 편심되게 배치되어 회전자재토록 설치된 로우터(2)와, 로우터(2)에 형성된 홈(7)에 이동 자재토록 삽입되어 고정된 케이싱(1)의 내주벽과 접하면서 진퇴되는 복수개 베인(3)으로 구성되어, 흡입구(5)로 유입된 유체는 제1도의 (a)(b)(c)(d)에 표현된 바와같이 그 유체를 수용하고 있는 작동실(4)이 로우터(2)가 회전됨에 따라 점차 축소되기 때문에 압축되어 압축된 유체는 토출구(6)로 베출되게 된다.In general, the vane-type fluid compressor has a casing (1) as shown in FIG. 1, a rotor (2) disposed eccentrically in the casing (1) and installed to rotate freely, and a groove (7) formed in the rotor (2). Consists of a plurality of vanes (3) advancing in contact with the inner circumferential wall of the casing (1) inserted and fixed so as to move material, the fluid flowing into the suction port (5) (a) (b) (c) ( As represented by d), the working chamber 4 containing the fluid gradually shrinks as the rotor 2 rotates, so that the compressed and compressed fluid is ejected to the discharge port 6.

상기에서 작동실(4)을 형성하는 베인(3)은 로우터(2)와 함께 회전하면서 로우터의 홈(7)에 끼워진 스프링(8)의 탄발력 및 회전에 의한 원심력에 의하여 그 선단이 고정된 케이싱의 내주벽에 밀착되면서 진퇴되는 것으로 베인(3)이 고정된 케이싱의 내주벽을 항상 미끄럼운동하면서 회전하기 때문에 그 미끄럼운동 저항에 동반해서 동력손실이 크게 되어 비효율적이 되는 문제점이 있었다.The vane 3 forming the operating chamber 4 is fixed with the tip of the spring 8 inserted into the groove 7 of the rotor and the centrifugal force by the rotation while rotating together with the rotor 2. As the vane 3 rotates while always sliding in the inner circumferential wall of the fixed casing, the power loss increases with the sliding resistance, resulting in inefficiency.

또한, 베인이 쉽게 마모되고 고속 회전운전시 소착현상이 발생하여 압축기의 신뢰성이 저하될 뿐만아니라 압축기의 수명이 단축되고 소음도 크게 발생하게 되는 문제점이 있었다.In addition, the vanes are easily worn and sintering occurs during high-speed rotational operation, which lowers the reliability of the compressor and shortens the life of the compressor and greatly increases the noise.

한편, 상기의 문제점을 해결하기 위하여, 베인과 로우터가 내장된 케이싱이 구동수단에 의하여 회전되고 동력전달기구를 통하여 케이싱의 회전동력을 로우터에 전달하여 로우터가 케이싱과 동기회전토록 구성함으로써 케이싱의 내주벽에 대한 베인의 미끄럼이동 현상이 저감되도록 한 발명이 공개된 바 있다.On the other hand, in order to solve the above problems, the casing in which the vanes and the rotor are built is rotated by the driving means and the rotor transmits the rotational power of the casing to the rotor through the power transmission mechanism, so that the rotor is configured to rotate synchronously with the casing. Invention has been disclosed to reduce the sliding phenomenon of the vanes on the main wall.

그러나, 상기한 발명은 케이싱과 로우터를 다같이 동기회전시켜야 하므로 동력 소비가 많게 될 뿐만아니라 케이싱과 로우터를 동기회전시키기 위하여 별도의 동력전달기구를 설치하여야 하므로 그 구성이 복잡해지는 문제점이 발생하게 된다.However, the above-described invention requires a synchronous rotation of the casing and the rotor together, resulting in high power consumption, and a separate power transmission mechanism must be installed to synchronously rotate the casing and the rotor. .

본 고안은 상기한 제반 문제점을 해결하기 위하여 안출된 것으로서, 극히 단순한 구성으로 케이싱을 굴름운동 가능토록 하여 베인의 미끄럼저항을 저감시켜 효율이 향상되고 수명이 연장되며 고속회전으로 가동될 수 있는 유체압축기를 제공하는데 그 목적이 있다.The present invention was devised to solve the above problems, and it is possible to roll the casing in an extremely simple configuration to reduce the sliding resistance of the vane, which improves efficiency, extends the life, and can operate at high speed. The purpose is to provide.

상기의 목적을 달성하기 위한 본 고안은 케이싱과 케이싱내에 편심되게 배치되어 공지의 구동수단에 의하여 회전되는 로우터와, 로우터내에 방사 또는 임의각도 방향으로 형성된 복수개의 홈으로부터 진퇴되어 상기 케이싱의 내주면과 로우터 사이를 구획하여 복수의 작동실을 형성하는 베인을 포함하여 구성된 유체압축기에 있어서, 상기의 케이싱은 그 양단부가 유체압축기의 좌, 우측벽부에 끼워지고 상기 좌, 우측벽부의 케이싱의 양단부 사이에는 베어링이 설치되어 로우터의 회전으로 베인이 케이싱의 내주벽에 접하면서 회전될 때 케이싱과 베인 상이의 마찰토오크와 케이싱에 걸리는 토오크의 대소에 따라 케이싱의 회전운동 또는 케이싱과 베인 사이에 미끄럼 운동이 일어나게 되어 동력소모를 줄이면서 베인의 마모, 마찰이 저감되도록 구성된 것을 특징으로 한다.The present invention for achieving the above object is disposed in the casing and the casing eccentrically rotated by a known drive means, and the retracted from the plurality of grooves formed in the rotor in a radial or arbitrary angle direction and the inner peripheral surface and the rotor of the casing In a fluid compressor configured to include a vane partitioning therebetween to form a plurality of operating chambers, the casing includes both ends of which are fitted to the left and right wall portions of the fluid compressor and between the both ends of the casing of the left and right wall portions. When the vane is rotated while the rotor is in contact with the inner circumferential wall of the rotor, the rotational movement of the casing or the sliding motion occurs between the casing and the vane depending on the friction torque between the casing and the vane and the torque applied to the casing. Reduce vane wear and friction while reducing power consumption Characterized in that a.

케이스(80) 및 좌측벽부(40)에는 케이싱(10)의 내주벽과 로우터(20) 사이의 공간부와 연통되는 유체흡입구(71)와 토출구(72)가 형성되어 있고, 좌,우측벽부(40,50)는 내측방향으로 단턱져서 돌출된 축소직경부(41,51)가 각각 형성되어 있고, 상기 축소직경부(41,51)의 외주면과 케이싱(10)의 양단부 내주면 사이에 베어링이 설치되어 있다.The case 80 and the left wall portion 40 are formed with a fluid suction port 71 and a discharge port 72 communicating with the space between the inner circumferential wall of the casing 10 and the rotor 20, and the left and right wall portions ( 40 and 50 are each formed with reduced diameter portions 41 and 51 which protrude inwardly and are respectively provided with bearings between the outer circumferential surfaces of the reduced diameter portions 41 and 51 and the inner circumferential surfaces of both ends of the casing 10. It is.

로우터(20)는 좌측에 축(22)이 돌출되어 좌측벽부(40)에 회전 가능토록 삽입되어 있고, 로우터(20)의 우측에 축(21)이 우측벽부(50)와 케이스(80)를 관통하여 회전 자재토록 설치되어 있으며, 축(21)은 공지의 회전수단(미도시)과 연결되어 회전수단으로부터 동력을 전달받아 로우터(20)가 케이싱(10)내에서 회전되도록 되어 있다.The rotor 20 has a shaft 22 protruding from the left side and inserted into the left wall portion 40 so as to be rotatable, and the shaft 21 on the right side of the rotor 20 connects the right wall portion 50 and the case 80. It is installed through the rotating material, the shaft 21 is connected to a known rotating means (not shown) to receive power from the rotating means so that the rotor 20 is rotated in the casing 10.

상기와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

유체흡입구(71)를 통하여 유체가 흡입되고 공지의 회전수단(미도시)으로 로우터(20)를 회전시키면 로우터(20)의 홈(미도시)에 진퇴 가능토록 삽입된 베인(30)은 통상의 베인형 유체압축기와 같이 로우터(20)와 함께 회전하게 되는데, 상기의 로우터(20)는 케이싱(10)내에 편심되게 배치되어 회전되므로 케이싱(10)의 내주벽과 로우터(20) 사이에 형성되고 베인(30)에 의하여 구획된 작동실은 그 체적이 축소 또는 팽창하게 되고 흡입구(71)를 통하여 작동실로 유입된 유체는 작동실이 축소되는 동안 압축되어 토출구(72)를 통하여 토출되게 된다.When the fluid is sucked through the fluid inlet 71 and the rotor 20 is rotated by a known rotating means (not shown), the vanes 30 inserted into the grooves (not shown) of the rotor 20 may be inserted into a conventional apparatus. The rotor 20 is rotated together with the rotor 20 like the vane type fluid compressor. The rotor 20 is eccentrically disposed and rotated in the casing 10, and thus is formed between the inner circumferential wall of the casing 10 and the rotor 20. The operating chamber partitioned by the vanes 30 is reduced or expanded in volume, and the fluid introduced into the operating chamber through the suction port 71 is compressed and discharged through the discharge port 72 while the operating chamber is reduced.

상기에서 베인(30)은 로우터(20)가 회전될 때 스프링(미도시)의 탄발력과 원심력에 의하여 베인(30)의 상부면이 케이싱(10)의 내주벽에 압착되면서 미끄럼이동을 하게 되는데, 케이싱(10)은 그 양단부와 좌,우측벽부(41,51)의 축소직경부 사이에 베어링이 설치되어 회전자재토록 되어 있으므로, 케이싱(10)과 베인(30)사이의 마찰력에 의해 케이싱(10)의 회전운동 또는 케이싱(10)과 베인(30) 사이에 미끄럼 운동이 일어나게 되어 동력소모를 줄이면서 베인의 마모, 마찰을 저감시키게 된다.In the vane 30, when the rotor 20 is rotated, the upper surface of the vane 30 is squeezed to the inner circumferential wall of the casing 10 by sliding force and centrifugal force of a spring (not shown). Since the casing 10 has a bearing installed between the both ends thereof and the reduced diameter portions of the left and right wall portions 41 and 51 to rotate the casing 10, the casing 10 is formed by the frictional force between the casing 10 and the vane 30. 10) the sliding movement between the casing (10) and the vanes (30) is generated to reduce the wear and friction of the vanes while reducing the power consumption.

그러므로, 본 고안은 베인의 마로, 마손이 저감되어 효율이 향상될 뿐 아니라 수명이 연장되고 정숙하고 안정된 운전을 확보할 수 있으며, 압축기를 고속화 또는 소형화할 수 있는 이점이 있다.Therefore, the present invention can reduce the wear and tear of the vane, improve the efficiency, as well as to prolong the life, ensure quiet and stable operation, and has the advantage of speeding up or downsizing the compressor.
