Description

회전형 베인을 이용한 에어공구의 회전장치 {Revolution apparatus with rotating vanes on the air tools}Revolution apparatus with rotating vanes on the air tools

본 발명은 에어공구의 회전장치에 관한 것으로 더욱 상세하게는 공기압력을 이용하여 작동하는 공압그라인더나 고압드릴과 같은 에어공구의 회전장치를 기존의 마찰형에서 회전형으로 변경하여 회전장치의 수명을 대폭 향상한 회전형 베인을 이용한 에어공구의 회전장치에 관한 것이다.The present invention relates to a rotating device of an air tool, and more particularly, to change the rotating device of an air tool such as a pneumatic grinder or a high pressure drill operated by using air pressure from a conventional friction type to a rotating type to improve the life of the rotating device. The present invention relates to an air tool rotating apparatus using a greatly improved rotary vane.

종래의 에어공구는 도 1에 도시된 바와 같이 고압공기 주입부(1)를 통하여 고압의 공기가 주입되면 밸브(2)를 통하여 카바(25)와 우측 실링플래이트(6)와 실린더(7)에 있는 에어홀(24)을 통하여 고압의 공기가 주입되고 주입된 고압의 공기는 로터(8)를 회전하기 위하여 힘이 작용한다.As shown in FIG. 1, when a high pressure air is injected through the high pressure air inlet 1, the conventional air tool is applied to the cover 25, the right sealing plate 6, and the cylinder 7 through the valve 2. The high pressure air is injected through the air hole 24, and the high pressure air is applied by the force to rotate the rotor 8.

상기와 같은 작용을 위하여 로터(8)의 베어홈(9)을 파 놓고 이 홈에 베인을 삽입하여 공기가 베인을 밀어서 로터(8)를 회전시키도록 한다.For this operation, the bare groove 9 of the rotor 8 is dug and a vane is inserted into the groove so that the air pushes the vanes to rotate the rotor 8.

베인(22)은 로터(8)가 회전하게 되면 원심력에 의하여 실린더(7)와 접촉하도록 되어 있고 또한, 로터(8)에서 발생된 회전력은 베벨기어(13)에 전달되어진다.The vane 22 comes into contact with the cylinder 7 by centrifugal force when the rotor 8 rotates, and the rotational force generated by the rotor 8 is transmitted to the bevel gear 13.

직각으로 힘을 전달하기 위하여 다른 베벨기어(14)와 물려져 있으며 그라인더(20)를 회전시켜 작업이 가능하도록 한다.In order to transmit the force at right angles to another bevel gear (14) and to rotate the grinder 20 to enable the work.

그라인더(20)는 사용목적에 따라서 드릴 외 다른 공구로 사용할 수 있으며 최대 회전속도 조절장치(4)가 최대속도에 도달하게 되면 밸브(2)를 밀어서 고압의 공기가 고압공기 배출구(3)로 바이패스하도록 한다.The grinder 20 can be used as a tool other than a drill, depending on the purpose of use. When the maximum rotational speed adjusting device 4 reaches the maximum speed, the grinder 20 pushes the valve 2 so that high pressure air is transferred to the high-pressure air outlet 3. Pass it.

그리고 베어링(5, 11, 15, 16)과 너트(12, 17, 19)와, 그라인더 카바(21)와, 그라인더(20)가 부착된도록 하는 플래이트(18)와, 고압의 공기가 로터(8)를 회전시킨 후 밖으로 배출되도록 하는 에어배출구(26)와, 로터의 좌우 베어링의 하우징 역할과 에어 실링의 역할을 하는 좌/우 실링플래이트(10, 6)로 구성되어 있다.Then, the bearings 5, 11, 15 and 16, the nuts 12, 17 and 19, the grinder cover 21 and the plate 18 to which the grinder 20 is attached, and the high pressure air are the rotor ( It is composed of an air discharge port 26 for discharging to the outside after rotating 8), and left and right sealing plates 10 and 6 serving as a housing of the left and right bearings of the rotor and air sealing.

또한, 도 2는 상기 도 1에서 A부분의 단면을 도시한 것으로 에어공구의 몸체를 보호하는 케이싱(23)과, 고압의 공기가 실린더로 유입되는 에어홀(24)과, 편심으로 설치되어 고압공기가 베인에 작동하도록 하는 실린더(7)와, 주입된 고압 공기가 베인을 밀어서 로터를 회전시키기 위하여 베인을 장착하기 위한 베어홈(9), 다수개의 날개형상으로 구성되어 로터가 회전할 때 베인홈 안에서 원심력에 의하여 실린더 내부에 칸막이를 형성하는 베인(22)과, 자신의 축을 회전축으로 하여 회전하는 로터(8)와, 고압 공기를 가압후 배출되어지는 에어 배출구(26)로 구성되어 있다.In addition, Figure 2 is a cross-sectional view of the portion A in Figure 1, the casing 23 to protect the body of the air tool, the air hole 24 through which high-pressure air flows into the cylinder, and is installed eccentrically A cylinder (7) which allows air to act on the vanes, a bare groove (9) for mounting the vanes to push the vanes to rotate the rotor, and a plurality of vanes to form a vane when the rotor is rotating It consists of the vane 22 which forms a partition inside a cylinder by the centrifugal force in the groove, the rotor 8 which rotates its own axis as a rotating shaft, and the air discharge port 26 discharged after pressurizing high pressure air.

또한, 고압의 공기가 내부로 주입되도록 실린더 안쪽에 홈이 파져 있고 베인(22)으로서 원심력에 의하여 실린더 벽면과 마찰하도록 되어 있다.In addition, a groove is formed in the cylinder so that high-pressure air is injected into the cylinder, and the vane 22 is rubbed with the cylinder wall surface by centrifugal force.

가압 후 배출되어지는 에어의 고압공기 배출구(26)는 실린더(7)의 우측변면에 홈이 파져 있으며 배출된 에어는 우측에서 모아져 밖으로 배출되도록 케이싱(23)에 배출구가 있다.The high pressure air outlet 26 of the air discharged after pressurization is grooved in the right side of the cylinder 7 and the discharged air is discharged in the casing 23 so that the discharged air is collected from the right side and discharged outward.

도 2에서는 로터의 회전은 시계반대방향으로 회전되어짐을 알 수 있다.In Figure 2 it can be seen that the rotation of the rotor is rotated counterclockwise.

그러나. 종래의 회전장치는 실린더(7)와 베인(22)이 접촉하면서 회전하도록 하여 실린더와 베인에 마모가 발생되는 문제점이 있었다.But. Conventional rotary devices have a problem that wear occurs in the cylinder and the vanes by rotating while the cylinder 7 and the vanes 22 are in contact.

다른 문제점은 베인(22)은 복합재를 사용함으로 쉽게 마모가 발생되었으며 마모된 찌거기가 실린더의 내벽에서 연마제와 같은 역할을 하여 마모를 촉진하고 이러한 마모에 따라 실린더와 로터와의 간격이 커지게 되어 가압해야 할 공기가 반대편으로 빠져나와 반대편 베인을 반대방향으로 힘을 가하게 되어져 효율의 감소와 토오크의 감소를 초래하게 되고 더욱이 베인의 마모 외에도 도 2에서 아래부분(B)인 로터(8)의 끝부분에서 베인에 가장 큰 전단응력이 전달되므로 베인파손의 문제점이 있었다.Another problem is that the vanes 22 are easily abraded by using a composite material, and the worn residue acts like an abrasive on the inner wall of the cylinder to promote wear, and the gap between the cylinder and the rotor increases according to the wear. The air to be discharged to the opposite side exerts a force on the opposite vanes in the opposite direction, which leads to a decrease in efficiency and a reduction in torque. Since the largest shear stress is transmitted to the vanes, there is a problem of vane breakage.

즉, 돌출되어진 베인이 힘을 받아서 그 위치에서 베인이 파손되어져 회전장치를 사용하지 못하게 하는데 가장 큰 문제점이 있었다.In other words, the most prominent problem is that the protruding vanes receive the force and the vanes are broken at the position so that the rotating device cannot be used.

따라서, 본 발명의 목적은 상기 문제점을 해결하기 위해 발명된 것으로 베인을 가벼운 금속 소재로 채택하고 베인의 팁부분에 슬립형 회전자로 변경함으로써 실린더의 마모를 줄이고 효율 감소 및 토오크 감소가 발생되지 않도록 하여 베일과 실린더를 반영구적으로 사용하는데 목적이 있다.Accordingly, an object of the present invention is to solve the above problems by adopting a vane as a light metal material and by changing the slip rotor to the tip of the vane to reduce the wear of the cylinder and to reduce the efficiency and torque reduction The purpose is to use the veil and cylinder semi-permanently.

상기 목적을 달성하기 위하여 본 발명은 에어공구의 내부 구조를 로터와 실린더가 접촉하도록 베인의 팁부분에 원호를 형성하고 이렇게 형성된 베인의 팁부분에 원형의 니들 베어링을 부착하여 원활한 회전운동을 할 수 있도록 회전형 베인을 이용한 에어공구의 회전장치를 달성하였다.In order to achieve the above object, the present invention forms a circular arc at the tip of the vane so that the rotor and the cylinder contact the inner structure of the air tool, and attaches a circular needle bearing to the tip of the vane so that a smooth rotational motion can be achieved. A rotating device of the air tool using the rotary vane was achieved.

Rotor 27 is formed by inserting the needle bearing 27 by inserting the groove at the tip of vane, which is the connection between the cylinder and the vane, and a plurality of blades, and inside the cylinder by centrifugal force in the vane groove when the rotor rotates A vane 28 is formed to form a partition and the tip of the vane is fitted with a vane 28 that is rotatable following the needle bearing. (7), the bare groove (9) for mounting the vanes so that the injected high pressure air pushes the vanes to rotate the rotor, the rotor (8) which rotates its own axis as the rotating shaft, and pressurizes the high pressure air It is composed of an air outlet 26 which is discharged out.

그리고 베인(28)은 가벼운 금속제를 사용하므로 도 2의 아랫부분(B)에서 베인이 쉽게 파손되어지는 것을 개선하였다.And since the vanes 28 are made of light metal, the vanes are easily broken at the lower part B of FIG. 2.

도 4는 바람직한 실시예로 도 3의 한부분을 확대한 것으로 상기 도 3에서 설명한 니들 베어링, 베인의 구조를 도시하고 있다.FIG. 4 is an enlarged view of a portion of FIG. 3 according to a preferred embodiment, and illustrates a structure of a needle bearing and a vane described in FIG. 3.

상기 니들 베어링(27)은 니들 베이링(27)의 원호가 베인(22)의 실린더쪽 팁부분의 원호에 홈이 밀착되어 원활하게 회전할 수 있도록 구성되어 있으며 이렇게 구성된 니들 베어링(27)은 실린더의 내부 면과 접촉하여 마모가 없이 회전할 수 있도록 구성되어 있다.The needle bearing 27 is configured such that the circular arc of the needle bearing 27 is smoothly rotated by the groove in close contact with the circular arc of the tip portion of the cylinder side of the vane 22. The needle bearing 27 is configured as a cylinder It is designed to be able to rotate without contact with the inner surface of the wearer.

이상에서 설명한 바와 같이, 본 발명은 베인을 가벼운 금속재로 사용하고 베인의 팁부분에 회전자를 채용하고 기존의 마찰형에서 회전형으로 변경함으로써 실린더의 마모가 획기적으로 감소되고 장시간 사용하여도 효율의 감소나 토오크 감소가 발생되지 않는 효과가 있으며 또한, 장시간 사용에도 실린더와 로터와의 간격이 증대하지 않으므로 베인은 반영구적으로 사용이 가능하도록 되었으며 부품의 교체시 회전자만 교체하면 계속 사용할 수 있는 효과가 있으므로 공구산업상 매우 유용한 발명인 것이다.As described above, the present invention uses the vane as a light metal material and employs a rotor at the tip of the vane and changes from the conventional friction type to the rotation type, which greatly reduces the wear of the cylinder and improves efficiency even when used for a long time. There is no effect of reducing or reducing torque. Also, the gap between the cylinder and the rotor does not increase even for long time use, so the vanes can be used semi-permanently. Therefore, it is a very useful invention in the tool industry.
