Abstract

본 발명은 교류발전기의 방폭장치에 관한 것이다.The present invention relates to an explosion-proof device of an alternator.

본 발명은 전후방으로 밀폐구성되는 한쌍의 브라켓(1)(1′), 상기 브라켓(1)(1′)의 내측에 끼워지는 전ㆍ후방 베이링(2)(2′)에 축설되며 일측에 슬립링(3)이 끼워지고 타측에 폴리(4)에 끼워지는 회전축(5), 상기 회전축(5)에 축설되며 양측에 냉각팬(6)을 갖춘 회전자(7), 상기 브라켓(1)(1′)의 내주면에 고정 설치되는 고정자(8), 상기 슬립링(3)의 상측에 구비되며 브러시 홀더(90)와 스프링(91)에 의해 탄지된 상태에서 상기 슬립링에 면 접촉되는 브러시(9), 상기 브라켓(1′)의 일단부에서 상기 후방 베어링(2′)의 상측까지 연통형성되며 상기 슬립링(3)에 의해 발생되는 상기 브러시 분말을 안내하는 배출구(10)로 구성된 교류발전기에 있어서, 상기 후방 베어링(2′)과 상기 슬립링(3)의 사이에 위치하는 상기 회전축(5)에 축설되며 상기 회전축의 회전시 일체로 회전하며 상기 브러시에서 발생하는 불꽃이 상기 브라켓(1)(1′)의 외부로 유출되어 미연가스에 점화됨을 방지하는 방폭수단(12)으로 구비되어 구성된다.The present invention is constructed in a pair of brackets (1) (1 ') which are sealed in the front and rear, front and rear bearings (2) (2') fitted to the inside of the bracket (1) (1 ') and on one side A rotary shaft 5 fitted with a slip ring 3 and fitted to the poly 4 on the other side, a rotor 7 arranged on the rotary shaft 5 and having a cooling fan 6 on both sides, and the bracket 1 A stator 8 fixedly installed on an inner circumferential surface of 1 ', and provided on an upper side of the slip ring 3 and brushed in surface contact with the slip ring in a state held by the brush holder 90 and the spring 91. (9), an alternating current consisting of a discharge port (10) communicating with one end of the bracket (1 ') to the upper side of the rear bearing (2') and guiding the brush powder generated by the slip ring (3). In the generator, it is arranged on the rotary shaft (5) located between the rear bearing (2 ') and the slip ring (3) and integrally rotates when the rotary shaft is rotated. It is composed of explosion-proof means 12 for preventing the spark generated from the brush is leaked to the outside of the bracket (1) (1 ') to ignite the unburned gas.

본 발명은 교류발전기가 소형선박에 설치되었을 경우 교류발전기의 구동시 발생되는 불꽃이 교류발전기의 본체외부로 배출된 후 엔진 룸에 체류되어 있는 가연성 가스에 점화, 폭발될 우려를 방지하므로서 제품의 신뢰성을 향상시키게 된다.According to the present invention, when the alternator is installed on a small ship, the spark generated during the operation of the alternator is discharged out of the main body of the alternator, and thus the risk of ignition and explosion in the combustible gas staying in the engine room is prevented. Will improve.
