본 고안은 철도차량 디젤전기기관차 축상(1)베어링의 온도 확인장치에 관한 것으로, 보다 상세하게는 축상박스 및 축상커버 표면에 온도감지 페인트(2-1,2-4,4)를 도색 하거나 온도감지 테이프(2-2,2-3,3)를 부착하여 베어링 내부온도가 일정온도 이상 상승하였을 경우 변색이 되어 육안으로 확인할 수 있어 상기 축상 베어링의 소손을 조기에 방지하도록 하는 철도차량 디젤전기기관차 축상베어링의 온도확인 장치에 관한 것이다.The present invention relates to a temperature checking device for the shaft (1) bearing of a railroad diesel electric locomotive, and more specifically, the temperature sensing paint (2-1, 2-4, 4) is painted on the surface of the shaft box and the shaft cover, Attached to the sensing tapes (2-2, 2-3, 3), when the internal temperature of the bearing rises above a certain temperature, it becomes discolored and can be checked with the naked eye so as to prevent burnout of the axial bearings early. It relates to a temperature checking device for an axial bearing.

종래의 축상베어링 박스 우측상부에 축상발열 감지 장치인 Stench Bomb (5)이 설치되어 축상 내부의 과도한 발열이 발생시 105℃에서 동작하여 내부의 악취가스를 외부로 배출시켜 발열을 경고하고 있으나, 객실과 운전실의 밀폐로 인한 후각으로 확인이 곤란하다. 또 Stench Bomb 고열에도 작동이 되지 않는 것도 있고, 작동 후 Stench Bomb 작은 배출 구멍(5-1)이 뚫어져 있는 것을 발견하기가 곤란하였다.Stench Bomb (5), which is an axial fever detection device, is installed on the upper right side of the conventional axial bearing box and operates at 105 ° C when excessive heat is generated inside the shaft, thereby discharging the odor gas inside to warn the fever. It is difficult to see because of the smell of the cab. In addition, it was difficult to find that the Stench Bomb small discharge hole 5-1 was drilled even after the Stench Bomb was heated at a high temperature.

그리고 정차시 시간이 지남에 따라 발열부위가 냉각됨에 따라 정상으로 판단 하여 계속적으로 사용시 발열 사고로 연결되는 문제점이 발생되었다.In addition, as the heating part cools down as time passes, it is determined that it is normal and a problem occurs that leads to heat generation accident when used continuously.

여객 및 화물 운행에 따른 디젤전기기관차의 축상베어링 관리에 많은 인력을 투입하고 있으나 발열 및 축 절손으로 도중고장이 연간 3.5대에 달하고 있어 차량운행 지연과 시간의 촉각을 다투는 화물운반에 막대한 지장을 주고 있어 이에 따른 특단의 관리검수 대책이 요구되는 결점이 있었다.Although a lot of manpower is invested in the shaft bearing management of diesel electric locomotives according to passengers and cargo operations, there are 3.5 faults during the year due to heat generation and shaft loss. Therefore, there was a drawback that a special management inspection measure was required accordingly.

본 고안은 상기와 같은 종래 기술의 제반 문제점을 해결하기 위한 것으로 그 목적은 상기 축상베어링 내부 이상 과열상태 판정을 위해 축상박스(1) 및 축상커버(2) 표면에 온도변화에 따라 변색기능이 있는 온도감지페인트를 도색하고 온도감지테이프를 부착함으로써 누구나 쉽게 축상베어링의 과부하 운행 및 내부 이상에 의한 과열상태를 용이하게 시각적으로 확인할 수 있어 상기 축상베어링 박스 전체를 적기교체로 소손 사고를 미연에 예방할 수 있도록 하는 철도차량 디젤전기기관차 축상베어링의 온도확인 장치에 관한 것이다. The present invention is to solve all the problems of the prior art as described above, the purpose of which is to change the temperature on the surface of the shaft box (1) and the shaft cover (2) to determine the abnormal overheating state inside the shaft bearing. By painting the temperature sensing paint and attaching the temperature sensing tape, anyone can easily visually check the overheating condition due to the overload operation of the shaft bearing and the internal abnormality, so that the whole shaft bearing box can be replaced in a timely manner to prevent burnout accidents. The present invention relates to a temperature checking device for an axial bearing of a rolling stock diesel electric locomotive.

본 고안의 첨부된 도면을 참조하여 실시 예를 상세히 설명한다.Embodiments will be described in detail with reference to the accompanying drawings of the present invention.

(도-1)은 본 고안의 실시 예에 따른 축상베어링의 온도확인 장치 사용상태도이다.(Fig. 1) is a state diagram of the temperature checking device of the axial bearing according to the embodiment of the present invention.

도-1과 도-2에서 도시된 것과 같이 탄소강 주물로 제작된 축상커버 및 축상박스 내에 있는 베어링의 이상과열상태를 시각적으로 확인할 수 있는 온도감지 페인트 또는 테이프를 부착한 것이다.As shown in Figs. 1 and 2, the axial cover made of a carbon steel casting and a temperature-sensitive paint or tape to visually check the abnormal superheat state of the bearing in the axial box are attached.

축상커버 표면 중심부에 열 감지를 빠르게 확인할 수 있도록 중앙에 반원은 온도감지테이프(2-3)를 부착하고, 나머지에는 온도감지페인트(2-4)를 부착 도색한 것이다.In order to quickly check the heat sensing in the center of the axial cover surface, the semicircle is attached with a temperature sensing tape (2-3) in the center, and the temperature sensing paint (2-4) is attached with the rest.

축상커버 내부의 트러스트 블록의 발열감지를 할 수 있도록 축상커버 표면에 온도감지테이프(2-2)와 온도감지페인트(2-1)를 부착 도색한 것이다.The temperature sensing tape 2-2 and the temperature sensing paint 2-1 are attached to the surface of the shaft cover so as to detect the heat generation of the thrust block inside the shaft cover.

축상박스 발열감지를 할 수 있도록 축상커버 표면에 온도감지테이프(3)와 온도감지페인트(4)를 부착 도색한 것이다.The temperature sensing tape (3) and the temperature sensing paint (4) are attached to the surface of the shaft cover in order to detect the heating of the shaft box.

철도차량인 디젤전기기관차의 동력을 이용 객차나 화물차를 편성 견인하고 있는데 있어 축상베어링이 소손에 이르는 과정은 운행중 윤활유 부족이나 게이지 절손, 베어링 뭉개짐, 베어링에 접촉되는 내륜자 및 외륜자의 이상접촉, 심한 충격, 등으로 베어링 내부 이상 마찰로 인한 열이 발생되어 열차 사고를 유발하게 한다.In the process of forming a towing car or truck by using the power of diesel electric locomotive, which is a railroad car, axial bearings are burned out. The severe impact, etc. generates heat due to abnormal friction inside the bearing, causing train accidents.

축상베어링의 소손에 이르는 온도는 계절에 따라 다소 차이가 있지만 100℃부터 윤활유의 증발과 내부 베어링이나 게이지등의 부품이 팽창으로 회전에 무리를 주어 고열이 발생되고 있다고 추정한다.The temperature leading to burnout of the axial bearing varies slightly depending on the season. However, it is estimated that high temperature is generated due to evaporation of lubricant and expansion of parts such as internal bearings and gauges.

축상 베어링의 온도는 기존 감지105℃에서 Stench Bomb 작동이 되었으나, 본 고안에서는 한 단계 감지능력을 낮추어 75℃에서 온도감지페이트 또는 온도테이프를 커버표면과 축상박스 외부에 부착하여 색상이 청색에서 적색으로 영원히 변함으로써 시각적으로 베어링이 발열여부를 확인할 수 있게 하여 조기에 교체 또는 검수 하여 사고를 미연에 방지할 수 있게 한 것이다.Although the temperature of the axial bearings has been operated with the bomb bomb at the conventional sensing 105 ℃, in this design, the detection ability is reduced by one step, and the temperature sensing tape or the temperature tape is attached to the cover surface and the outside of the shaft box at 75 ℃ to change the color from blue to red. By changing forever, it is possible to visually check whether the bearings are overheated and to replace or inspect it early to prevent accidents.

온도감지페이트 및 테이프의 가격이 저렴하며 탄소강 주물로 제작된 축상박스나 커버 표면에 쉽게 도색 및 부착이 가능하다. 사용주기는 약 1~3년 정도로 가능하나 운행시 자갈이나 이물질의 충격이나 먼지 부착 등으로 1년이 적당하다.Inexpensive temperature sensing tapes and tapes can be easily painted and attached to the shaft box or cover surface made of carbon steel castings. It can be used for about 1 ~ 3 years, but one year is appropriate due to the impact of gravel or foreign materials or adhesion of dust.

이상에서 본 고안이 바람직한 실시 예에 대하여 설명했으나 본 고안의 상기한 실시 예에 한정되지 않고 본 고안이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와 같은 변경은 기재된 청구범위 내에 있게 된다.Although the present invention has been described with reference to the preferred embodiment is not limited to the above-described embodiment of the present invention, anyone of ordinary skill in the art to which the present invention belongs, of course, various modifications are possible, such as Changes are intended to fall within the scope of the claims set forth.

이상에서 설명한 바와 같이 본 고안에 의하면, 축상커버(2)나 축상박스(1) 표면에 부착된 온도감지페인트 및 테이프의 변색에 의해 비 숙련자도 육안으로 쉽게 과열상태를 확인할 수 있어, 소손사고를 획기적으로 감소하는 효과가 있다.As described above, according to the present invention, by the discoloration of the temperature sensing paint and the tape attached to the surface of the shaft cover 2 or the shaft box 1, even an inexperienced person can easily check the overheating state with the naked eye. There is a dramatic decrease in effect.

도중고장 사고발생시 투입되는 많은 인력과, 열차지연에 따른 반환금등, 위와 같은 고안을 적용하여 도중고장 사고를 미연에 방지하므로 인한 철도의 안전운행에 따른 신뢰도를 높이는 효과도 있다, By applying the above devises such as a large number of manpower that is input in the event of a road accident and a return due to a train delay, it is also effective to increase the reliability of railroad safety due to preventing accidents.
