Description
본 고안은 철도차량용 견인전동기의 유입먼지 제거장치에 관한 것으로, 더욱 상세하게는 견인전동기의 작동시 내부로 내부로 유입되는 먼지를 최소하여 냉각능력이 떨어지는 것을 방지할 뿐만 아니라, 고장율을 낮출수 있는 철도차량용 견인전동기의 유입먼지 제거장치에 관한 것이다.The present invention relates to an inlet dust removal device of a traction motor for a railway vehicle, and more particularly, to minimize the dust flowing into the inside of the traction motor when operating the traction motor, to prevent the cooling capacity from dropping, and to reduce the failure rate. The present invention relates to a device for removing dust inflow of a traction motor for rolling stock.
일반적으로 종래에는 철도차량에 사용되는 견인전동기는 도 1 에 도시된 바와 같이, 본체(2)의 내경측에 권선코일부(4)가 형성되어 있으며, 상기 권선코일부(4)의 내측에 중앙에는 회전되는 로우터(11)에 쿨링팬(6)이 형성되어 있다.In general, as shown in FIG. 1, a traction motor conventionally used for a railway vehicle has a winding coil part 4 formed on an inner diameter side of a main body 2, and has a center inside the winding coil part 4. The cooling fan 6 is formed in the rotor 11 to be rotated.
상기 로우터(11)에 형성된 쿨링팬(6)은 로우터(11)의 회전시 발생되는 열을 낮추기 위해 형성되어 있다.The cooling fan 6 formed in the rotor 11 is formed to lower heat generated when the rotor 11 rotates.
또한, 쿨링팬(6)에 의해 유입되는 공기를 원활하게 유입되도록 본체(2)의 상부 일측에는 공기가 유입되는 냉각공기 유입부(8)를 갖는 커버덕트(9)가 형성되어 있다.In addition, a cover duct 9 having a cooling air inlet 8 through which air is introduced is formed at one upper side of the main body 2 so as to smoothly introduce the air introduced by the cooling fan 6.
커버덕트(9)는 외부공기중의 무거운 먼지 등이 가라앉아 유입되는 것을 방지하기 위해 측면에서 유입되도록 꺾여져 있다.The cover duct 9 is bent so as to flow from the side to prevent heavy dust and the like from sinking in the outside air.
또한, 또한 커버덕트(9)에는 외부측의 큰 이물질(종이조각 등)이 유입하지 못하도록 메쉬망이 씌워져 있다.In addition, the cover duct 9 is covered with a mesh net to prevent large foreign matter (such as paper scraps) from entering the outside.
그러나, 상기와 같은 구성으로 인해 로우터(11)의 회전에 의해 쿨링팬(6)이 같이 회전되기때문에 외부의 공기는 커버덕트(9)를 통해 유입되는데 이때에 유입되는 먼지는 거의 걸러지지 않는다.However, since the cooling fan 6 is rotated together by the rotation of the rotor 11 due to the configuration as described above, the outside air is introduced through the cover duct 9, and dust introduced at this time is hardly filtered.
따라서, 커버덕트(9)를 통해 유입되는 외부의 공기는 본체(2)상에 형성된 에어배출구(10)를 통해 배출되는데 이때에 유입된 공기는 권선코일부(4) 및 로우터(11)의 표면에 맞닿음되면서 배출되지 못하고 쌓이게 되는 문제점 있다.Therefore, the outside air introduced through the cover duct 9 is discharged through the air outlet 10 formed on the main body 2, the air introduced at this time is the surface of the winding coil portion 4 and the rotor 11 There is a problem that can not be discharged while being stacked.
따라서, 견인전동기를 사용함에 있어 장시간 동안 사용되면 내측에 먼지는 계속쌓이게 되므로 정기적으로 청소해주지 않으면 견인전동기 내부가 쿨링팬(6)에 의해서도 원활하게 냉각되지 않고 발열량이 높아져 파손되거나 회전 효율이 떨어지는 문제점이 발생되고 있다.Therefore, when the traction motor is used for a long time, since the dust continues to accumulate on the inside, unless it is cleaned regularly, the inside of the traction motor does not cool smoothly even by the cooling fan 6, and the heat generation is high, resulting in a problem of damage or inferior rotation efficiency. Is occurring.
따라서, 본 고안은 상기와 같은 종래의 문제점을 감안하여 창안된 것으로, 그목적은 견인전동기의 작동시 내부로 내부로 유입되는 먼지를 최소하여 냉각능력이 떨어지는 것을 방지하고, 먼지의 유입을 최소한으로 줄일 수 있기 때문에 정기적으로 시행하는 정비작업을 연장시킬 수 있는 철도차량용 견인전동기의 유입먼지 제거장치를 제공함에 있다.Therefore, the present invention was devised in view of the conventional problems as described above, and the purpose thereof is to minimize the dust flowing into the inside of the traction motor when operating, thereby preventing the cooling capacity from falling and minimizing the inflow of dust. The present invention provides a dust removal device for a traction motor for a railway vehicle, which can be extended so that maintenance work performed regularly can be extended.

In a traction motor for a railway vehicle comprising an air outlet formed on an outer circumferential side of a cooling fan so as to flow through and exchange heat exchanged inside, an air inlet portion of a cover duct is formed on an inner lower side of the cooling duct and is introduced into the air by a cooling fan. Dust is formed in the dust removal portion formed so as to be supported vertically away from the ground to the lower side by its own weight, dust removal portion The flow path is formed so that the discharge hole is located inside the main body and is located on the side of the discharge port so that the suction force is generated so that the fallen dust is sucked out by the discharge pressure generated at the discharge port of the main body, and the dust flowing in the air inlet is removed. The compressed air is composed of a purge air inlet formed at a position horizontal to the ground so that the air is bent by the partition plate and introduced into the body.
상기와 같이 구성된 본 고안의 철도차량용 견인전동기의 유입먼지 제거장치를 첨부된 도면을 참조하여 아래와 같이 설명한다.With reference to the accompanying drawings, the inlet dust removal apparatus of the traction motor for railway vehicles of the present invention configured as described above will be described below.
도 2 는 본 고안의 철도차량용 견인전동기의 유입먼지 제거장치를 나타내는 도면이다.2 is a view showing the inflow dust removal device of the traction motor for railway vehicles of the present invention.
본 고안은, 도 2에 도시된 바와 같이, 본체(20)의 내경측에 형성된 권선코일부(30)로 전원인가되면 중앙에 형성된 로우터(31)는 회전된다.In the present invention, as shown in Figure 2, when the power is applied to the winding coil portion 30 formed on the inner diameter side of the main body 20, the rotor 31 formed in the center is rotated.
상기와 같이 본체(20)의 내부측에서 로우터(31)가 회전되면, 로우터(31)와 상기 로우터(31)의 끝단에 형성된 쿨링팬(34)이 동시에 회전되어 외부의 공기는 흡입된다.When the rotor 31 is rotated inside the main body 20 as described above, the rotor 31 and the cooling fan 34 formed at the end of the rotor 31 are rotated at the same time, and the outside air is sucked in.
쿨링팬(34)의 회전에 의해 본체(20)의 내부측으로 공기를 흡입하게 될때에 외부측에 공기는 정화되지 않은 상태로 커버덕트(22)의 공기유입부(23)로 유입된다.When the air is sucked into the inside of the main body 20 by the rotation of the cooling fan 34, the air flows into the air inlet 23 of the cover duct 22 without being purified.
이때에 커버덕트(22)의 공기유입부(23)로 유입되는 외부공기는 일차적으로 쿨링팬(34)에 의해 유입되면서 무거운 먼지는 자중에 의해 떨어져 하부측에 형성된 먼지제거부(26)로 떨어진다.At this time, the outside air flowing into the air inlet 23 of the cover duct 22 is primarily introduced by the cooling fan 34, and heavy dust falls by its own weight and falls into the dust removing unit 26 formed on the lower side. .
커버덕트(22)의 공기유입부(23)는 본체(20)의 내부측으로 공기를 유입시킬 수 있는 정화공기유입부(28)가 형성된다.The air inlet 23 of the cover duct 22 is provided with a purge air inlet 28 through which air can be introduced into the main body 20.
상기의 정화공기유입부(28)는 커버덕트(22)의 내측에 분할판(24)에 의해 유입되는 공기와 먼지가 분리되도록 형성된다. 즉, 분할판(24)에 의해 일정한 속도에 의해 흡입되는 공기는 공기중에 섞여서 들어오는 먼지중 무거운 먼지는 분할판(24)측으로 꺾여져 진입하지 못하고 하부측으로 떨어진다.The purge air inlet 28 is formed to separate the air and dust introduced by the partition plate 24 inside the cover duct 22. That is, the air sucked at a constant speed by the divider 24 is mixed in the air and heavy dust of the incoming dust is bent to the divider 24 side and falls into the lower side without entering.
이는 흡입에 의한 속도에 의해 커버덕트(22)로 유입된 먼지를 포함한 공기는 분할판(24)의 하부측에 형성된 정화공기유입부(28)로 유입되면서 급격하게 공기의 흐름이 바뀌기 때문에 흡입되는 먼지에는 원심력이 작용되어 바깥측으로 뛰쳐나가려는 성질때문에 공기보다 무거운 먼지를 분리하기 쉽다.This is because the air containing the dust introduced into the cover duct 22 by the speed of the suction flows into the purification air inlet 28 formed on the lower side of the partition plate 24, so that the air flow changes rapidly, It is easy to separate dust that is heavier than air because of the property that centrifugal force is applied to the dust to jump outward.
또한, 분할판(24)의 하부측으로 정화공기유입부(28)가 형성되어 있기 때문에흡입되는 공기는 먼지가 분리되는 작용으로 무거운 먼지는 급격하게 꺾여지면서 흡입되므로 바깥측으로 쏠리면서 흡입되는 먼지는 하부측 즉, 먼지제거부(26)를 통해 배출되고 정화된 공기는 정화공기유입부(28)로 바로 꺾여져 유입된다.In addition, since the purge air inlet 28 is formed at the lower side of the divider 24, the sucked air is sucked while the heavy dust is sharply bent by the action of separating the dust, so the dust sucked while being moved to the outside is lowered. In other words, the air discharged and purified through the dust removing unit 26 is bent into the purified air inlet 28 and is introduced.
정화공기유입부(28)로 유입된 먼지가 제거된 공기는 본체의 로우터(11) 및 권선코일부(30)의 사이를 통과하면서 발생된 열을 식히도록 열교환된 후에 쿨링팬(34)에 의해 본체(20)밖으로 배출구(32)를 통해 데워진 공기를 배출시킨다.The air from which the dust introduced into the purifying air inlet 28 is removed is heat exchanged to cool the generated heat while passing between the rotor 11 and the winding coil 30 of the main body, and then by the cooling fan 34. The warmed air is discharged through the outlet 32 to the outside of the main body 20.
또한, 먼지제거부(26)의 하부측으로 떨어진 먼지등은, 본체(20)의 외주면측에 길이방향으로 덕트형상의 흐름관로부(25)를 형성하여 배출홀(36)을 쿨링팬(34)의 측면 위치에 관통되게 형성하므로 흡입력을 발생시킨다.In addition, the dust falling to the lower side of the dust removing unit 26, the duct-shaped flow passage 25 in the longitudinal direction on the outer peripheral surface side of the main body 20 to form a discharge hole 36 to the cooling fan 34 It is formed so as to penetrate the side position of the suction force.
따라서, 상기 먼지제거부(26)로 유입된 무거운 먼지를 포함한 공기가 흐름관로부(25)로 흘러 배출홀(36)로 배출될시 로우터(31) 및 권선코일부(30)를 거치지 않고 바로 쿨링팬(34)측으로 유입된다.Therefore, when air containing heavy dust introduced into the dust removing unit 26 flows into the flow passage 25 and is discharged into the discharge hole 36, the air is not immediately passed through the rotor 31 and the winding coil unit 30. Flowing into the cooling fan 34 side.
흐름관로부(25)의 배출홀(36)로 배출된 무거운 먼지를 포함한 공기는 쿨링팬(34) 측으로 흡입된 후에 정화공기유입부(28)로 유입된 공기와 같이 배출구(32)로 배출된다.Air containing heavy dust discharged to the discharge hole 36 of the flow passage part 25 is sucked toward the cooling fan 34 and then discharged to the discharge port 32 like the air introduced into the purification air inlet 28. .
상기와 같이 커버덕트(22)를 통해 유입되는 흡입공기중에서 무거운 먼지 등을 제거하고, 먼지가 제거된 공기만을 본체(20)의 내부측에 형성된 권선코일부(30) 및 로우터(31)를 통과하도록 하므로 그사이에 먼지등이 적체되는 것을 방지할 수 있다.As described above, heavy dust or the like is removed from the intake air introduced through the cover duct 22, and only the air from which the dust is removed passes through the winding coil part 30 and the rotor 31 formed inside the main body 20. It is possible to prevent the accumulation of dust in between.
또한, 커버덕트(22)의 내측에 형성된 먼지제거부(26)로 떨어져 제거된 먼지를 포함한 공기는 본체(20)내부측으로 흐르지 않고 바깥측으로 흐르다가 배출되도록 흐름관로부(25)를 형성하고 있으며 마지막 배출될시에 필요한 흡인력을 발생시키기 위해 흐름관로부(25)의 배출홀(36)을 쿨링팬(34)측에 관통되게 형성시킨 특징이 있다.In addition, the air including the dust removed by the dust removal portion 26 formed inside the cover duct 22 is formed in the flow passage 25 so that the air flows to the outside without flowing to the inside of the main body 20 is discharged. In order to generate the necessary suction force when the last discharge is characterized in that the discharge hole 36 of the flow passage portion 25 is formed to pass through the cooling fan 34 side.
따라서, 쿨링팬(34)의 회전시 발생되는 흡입력에 의해 배출홀(36)에서도 흡인력이 발생되므로 먼지제거부(26)는 흐름관로부(25)를 따라 흡입되는 특징이 있다.Therefore, since the suction force is also generated in the discharge hole 36 by the suction force generated when the cooling fan 34 rotates, the dust removing unit 26 is sucked along the flow passage part 25.
본 고안은 먼지제거부(26) 및 정화공기유입부(28)에 의해 서로 분리되어 있어 흡입되는 공기중에 포함된 먼지 등의 이물질을 분리시킬 수 있다.The present invention is separated from each other by the dust removal unit 26 and the purifying air inlet 28 can separate the foreign substances such as dust contained in the air sucked.
상기와 같은 본 고안의 철도차량용 견인전동기의 유입먼지 제거장치에 의해 견인전동기의 작동시 내부로 내부로 유입되는 먼지를 최소하여 냉각능력이 떨어지는 것을 방지할 수 있는 효과가 있다.By the inflow dust removal device of the railway vehicle traction motor of the present invention as described above has the effect of preventing the cooling capacity is reduced by minimizing the dust introduced into the inside when the traction motor operates.
또한, 먼지의 유입을 최소한으로 줄일 수 있기 때문에 정기적으로 시행하는 정비작업을 연장시킬 수 있는 효과도 있다.In addition, since the inflow of dust can be reduced to a minimum, there is an effect of extending the maintenance work to be carried out regularly.
