Description
본 발명은 전동차에 사용되는 견인전동기의 회전축을 지지하는 구동측 베어링을 보호하도록 된 디플렉터(deflector)에 관한 것으로, 특히 단일체로 이루어지고 오일배출구멍이 형성되어 이물질 침투 및 오일이 베어링쪽으로 유입되는 것을 방지할 수 있도록 된 견인전동기용 디플렉터에 관한 것이다.The present invention relates to a deflector which protects a bearing on a drive side supporting a rotating shaft of a traction motor used in an electric vehicle. In particular, the deflector is formed of a single body and an oil discharge hole is formed to allow foreign matter to penetrate into the bearing. The present invention relates to a deflector for a traction motor that can be prevented.
일반적으로, 전동차에는 각종 전동기가 장착되어 전동차에 필요한 동력을 제공하게 되는 바, 이러한 전동기내에 있는 구동측 베어링의 주변 구조는 도 3 에서 도시된 바와 같이, 베어링커버(103)내에 감싸여진 베어링(104)내에 샤프트(101)가 설치되고, 이 샤프트(101)와 함께 회전되는 베어링스토퍼(102)가 회전되는데, 이 베어링스토퍼(102)의 전방에는 회전체(105)와 고정체(106)로 이루어지는 디플렉터가 설치되어 있다.In general, the electric vehicle is equipped with a variety of electric motors to provide the power required for the electric vehicle, the peripheral structure of the drive-side bearing in the electric motor is a bearing 104 wrapped in the bearing cover 103, as shown in FIG. ), A shaft 101 is installed, and a bearing stopper 102 rotated together with the shaft 101 is rotated, and the front of the bearing stopper 102 is composed of a rotating body 105 and a fixed body 106. Deflector is installed.
여기서, 상기 디플렉터는 베어링(104)쪽으로 기어박스의 오일이나 이물질이 침투되는 것을 방지하도록 된 것으로, 이 디플렉터의 회전체(105)와 고정체(106)는 일정간격 이격되면서 서로 분리설치되어 있는데, 이때 상기 회전체(105)가 회전되면서 오일의 침투를 방지하게 된다.Here, the deflector is to prevent oil or foreign matter from the gearbox penetrating into the bearing 104. The deflector's rotating body 105 and the fixing body 106 are separated from each other by a predetermined interval. At this time, the rotation body 105 is rotated to prevent the penetration of oil.
그러나, 종래의 디플렉터는 2개의 부품, 즉 회전체와 고정체로 이루어져 있기 때문에, 전동차의 운행중에 발생하는 진동과 축방향 흔들림으로 인해 견인전동기의 회전체 조립부가 흔들리게 되고, 이에 따라 상기 회전체와 고정체가 간섭을 일으켜 디플렉터가 정위치에서 이탈되는 문제점이 있었으며, 이러한 이탈문제로 인해 상기 회전체와 고정체 사이에 이물질이 침투되면서 결국 베어링에도 이물질이 침투하게 되는 문제점이 있었다.However, since the deflector of the related art is composed of two parts, that is, the rotating body and the fixed body, the rotating assembly of the traction motor is shaken due to the vibration and the axial shaking generated during the driving of the electric vehicle. There is a problem that the deflector is separated from the position due to the interference caused by the fixing body, foreign matter penetrates between the rotor and the fixed body due to this separation problem, there is a problem that foreign matter also penetrates into the bearing.
이에 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 디플렉터의 구조를 변경시킴으로써 베어링쪽으로 이물질 및 오일이 침투되는 것을 방지함은 물론, 디플렉터의 이탈을 방지할 수 있는 견인전동기용 디플렉터를 제공하는데에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, and by changing the structure of the deflector to prevent foreign substances and oil from penetrating into the bearing, as well as to provide a deflector for the traction motor that can prevent the deflector from falling off. The purpose is to.
도 1 은 본 발명에 따른 디플렉터의 조립상태를 나타내는 정면도,1 is a front view showing the assembled state of the deflector according to the present invention,
도 2 는 도 1 의 Ⅰ-Ⅰ선 단면도,2 is a cross-sectional view taken along line II of FIG. 1;

3 : 베어링커버 4 : 베어링3: bearing cover 4: bearing
5 : 디플렉터 6 : 오일배출구멍5: deflector 6: oil discharge hole
상기와 같은 목적을 달성하기 위한 본 발명은, 단일 고정체로 이루어지고서 일측에 오일배출 구멍이 형성된 디플렉터가 베어링스토퍼에 근접하게 설치된다.The present invention for achieving the above object, the deflector made of a single fixed body and the oil discharge hole is formed on one side is installed close to the bearing stopper.
이하 본 발명을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1 은 본 발명에 따른 디플렉터의 조립상태를 나타내는 정면도이고, 도 2 는 도 1 의 Ⅰ-Ⅰ선 단면도로서, 종래와 유사하게 견인전동기의 구동측에는 베어링 커버(3)내에 감싸여진 환형상의 베어링(4)이 샤프트에 설치되고, 이 샤프트(1)와 함께 회전되는 베어링스토퍼(2)가 상기 베어링(4) 및 샤프트(1)에 인접하게 설치되며, 이 베어링스토퍼(2)의 전방에 소정간격으로 이격되어 대략 환형상의 디플렉터(5)가 설치되되, 이 디플렉터(5)는 단일한 고정체로 이루어지고서 일측에는 적어도 하나의 오일배출구멍(6)이 상기 디플렉터(5)를 관통하도록 형성되어 있다.1 is a front view showing an assembled state of a deflector according to the present invention, and FIG. 2 is a cross-sectional view taken along line I-I of FIG. 1, and similarly to the prior art, an annular bearing wrapped in a bearing cover 3 on the driving side of the traction motor ( 4) is installed on the shaft, and a bearing stopper 2 which is rotated together with the shaft 1 is provided adjacent to the bearing 4 and the shaft 1, and a predetermined distance in front of the bearing stopper 2 is provided. The annular deflector 5 is spaced apart from each other, and the deflector 5 is formed of a single fixed body, and at least one oil discharge hole 6 is formed to penetrate the deflector 5 on one side.
여기서, 상기 베어링스토퍼(2)와 디플렉터(5)는 유막형성이 가능하도록 그 거리가 아주 가깝게 되도록 설치된다.Here, the bearing stopper (2) and the deflector (5) is installed so that the distance is very close so that the oil film can be formed.
따라서, 상기 디플렉터(5)가 단일한 고정체로 이루어져 있기 때문에 정위치에서 이탈되는 문제점이 없게되고, 이에 따라 상기 디플렉터(5)는 기어박스의 오일이나 이물질이 베어링(4)쪽으로 침투되는 것을 방지할 수 있음은 물론, 만일 견인전동기의 작동중 기어박스내의 오일이 베어링스토퍼(2)와 디플렉터(5)의 사이로 침투된다 하더라도 상기 디플렉터(5)의 오일배출구멍(6)을 통해 다시 기어박스내로 배출될수 있게 된다.Therefore, since the deflector 5 is composed of a single fixed body, there is no problem that the deflector 5 is released from the fixed position. Accordingly, the deflector 5 prevents oil or foreign matter from the gearbox from penetrating into the bearing 4. Of course, even if oil in the gearbox penetrates between the bearing stopper 2 and the deflector 5 during operation of the traction motor, the oil is discharged back into the gearbox through the oil discharge hole 6 of the deflector 5. It becomes possible.
이상 설명한 바와 같이 본 발명에 따르면, 단일 고정체로 이루어지며 오일배출구멍이 형성된 디플렉터를 통해 차량운행 및 견인전동기 자체의 진동에 의한 디플렉터의 이탈사고를 방지하여 견인전동기의 작동 신뢰성을 향상시키는 한편, 그 부품수를 줄여 제작 및 보수유지 등의 작업효율을 향상시킬수 있는 효과가 있게 된다.As described above, according to the present invention, a deflector made of a single fixed body and having an oil discharge hole is formed to prevent an accidental deviation of the deflector due to vehicle operation and vibration of the traction motor itself, thereby improving operation reliability of the traction motor, and Reducing the number of parts has the effect of improving the work efficiency, such as manufacturing and maintenance.
