On the outer circumference, a cylindrical slip ring guide 7a in which the hollow 4 is formed so that the rotary shaft 5 is connected is installed so that the protrusion 11 of the slip ring and the end of the slip ring guide 7a overlap.

그러나, 이와 같은 종래 슬립링(1a)과 슬립링 가이드(7a)는 회전력에 의해 침투되는 이물질은 방지되나, 전류 통전을 위해 슬립링과 마찰되는 브러쉬(도시안됨)에서 발생되는 분진인 브러쉬 가루는 슬립링과 슬립링 가이드의 구조 때문However, such a conventional slip ring (1a) and slip ring guide (7a) is a foreign matter penetrated by the rotational force is prevented, but the brush powder which is dust generated from the brush (not shown) rubbed with the slip ring for the current supply Due to the structure of the slip ring and slip ring guide

에 원활히 배출되어지지 않기 때문에 브러쉬와 슬립링에 접촉 불량이 발생된다.Because it is not discharged smoothly, contact failure occurs in brush and slip ring.

상기 같은 문제점을 해결하고자 안출된 본 발명은 슬립링과 이의 외주에 설치되는 슬립링 가이드의 맞물리는 부분에 홈 또는 구멍을 형성하여 브러쉬 가루를 슬립링 가이드의 외부로 배출시켜 브러쉬와 슬립링의 접촉불량을 개선하고 발전기의 통전성을 향상시킨 것이다.The present invention devised to solve the above problems forms a groove or a hole in the engaging portion of the slip ring and the slip ring guide installed on the outer circumference thereof to discharge the brush powder to the outside of the slip ring guide to contact the brush and the slip ring. It is to improve the defect and improve the electrical conduction of the generator.

이를 위한 특징적인 수단으로는 계자 코일이 권선되고, 회전축(5)과 회전가능하게 연결된 로터(3), 그 후방에 브러쉬와 마찰되는 슬립링, 회전축(5)을 지지하는 베어링(6)으로 구성되는 발전기의 로터 어셈블리(2)에 있어서, 상기 슬립링의 로터 폴 대향부(12) 또는 돌출부(11)에 통공을 형성하거나, 슬립링 가이드의 일 끝단이나 저면에 홈이나 통공을 형성하여, 슬립링과 슬립링 가이드의 맞물리는 부분에 브러쉬가루 배출공을 형성하도록 한 것이다.Characteristic means for this consists of a rotor (3) wound around a field coil, rotatably connected to the rotating shaft (5), a slip ring rubbing with a brush at the rear thereof, and a bearing (6) for supporting the rotating shaft (5).

본 발명의 실시예를 첨부도면에 따라 상세히 설명하면 다음과 같다.An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 3(가)는 본 발명의 실시예로써, 로터 폴 후방과 베어링(6) 사이에 설치되는 슬립링(1b)과 슬립링 가이드(7b)의 상세한 사시 단면도이다.3A is a detailed perspective cross-sectional view of the slip ring 1b and the slip ring guide 7b installed between the rear of the rotor pole and the bearing 6 as an embodiment of the present invention.

상기 슬립링(1b)은 후방으로 요철진 돌출부(11)가 형성된 로터 폴 대향부(12)와 후방에 매끈하게 다듬질 가공되어 브러쉬(도시 안됨)와 접촉되는 브러쉬 접촉면(14)으로 구성되고, 축 중심에는 회전축(5)이 연결될 수 있도록 중공(4)이 형성되고, 슬립링의 로터 폴 대향면에서 요철진 안착부(13)까지 브러쉬가루 배출공(8)을 형성된 것이다.The slip ring 1b is composed of a rotor pole opposing portion 12 having a concave-convex protrusion 11 formed at the rear side and a brush contact surface 14 smoothly polished at the rear thereof to be in contact with a brush (not shown). A hollow 4 is formed in the center so that the rotation shaft 5 can be connected, and the brush powder discharge hole 8 is formed from the opposite surface of the rotor pole of the slip ring to the recessed and recessed seating portion 13.

이의 외주에 설치되어 슬립링 돌출부(11)와 끝단이 겹쳐지는 슬립링 가이드(7b)는 회전축(5)이 연결되도록 축 중심에 중공(4)이 형성된 원통형이고, 브러쉬가 슬립링의 브러쉬 접촉면(14)과 마찰될 수 있도록 원주면에 브러쉬홈(도시 안됨)이 형성된다.Slip ring guide (7b) is installed on the outer circumference of the slip ring projection 11 and the end overlaps is a cylindrical shape formed with a hollow (4) in the center of the shaft so that the rotary shaft 5 is connected, the brush is the brush contact surface of the slip ring ( Brush grooves (not shown) are formed on the circumferential surface so as to be rubbed with 14).

따라서, 슬립링(1b)의 외주면에 슬립링 가이드(7b)를 연결하면, 슬립링 가이드(7b)의 끝단이 슬립링의 돌출부(11)와 일부분 맞물려진다.Therefore, when the slip ring guide 7b is connected to the outer circumferential surface of the slip ring 1b, the end of the slip ring guide 7b is partially engaged with the protrusion 11 of the slip ring.

발전기의 구동을 위해 브러쉬가 스프링력에 의하여 슬립링의 브러쉬 접촉면과 접촉되면, 배터리의 전류가 브러쉬를 통해 슬립링에 통전되고, 이는 슬립링과 연결된 로터의 계자코일로 통전되어 로터에 자기장이 형성되고, 회전축이 회전되면 이에 따라 발생된 구심력에 의해 침투되는 이물질은 슬립링 가이드에 의하여 침투가 방지되고, 슬립링과 브러쉬의 마찰로 인하여 마모된 브러쉬 가루는 슬립링 가이드의 내주면에 모이고 이는 슬립링의 로터 폴 대향부에서 요철부로 형성된 브러쉬 가루 배출공(8)을 통해 외부로 배출된다.When the brush is contacted with the brush contact surface of the slip ring by the spring force for driving the generator, the current of the battery is energized through the brush to the slip ring, which is energized by the field coil of the rotor connected to the slip ring, forming a magnetic field in the rotor. When the rotating shaft is rotated, foreign matters penetrated by the centripetal force generated therein are prevented from penetrating by the slip ring guide, and the brush powder worn by the friction between the slip ring and the brush collects on the inner circumferential surface of the slip ring guide, which is a slip ring. It is discharged to the outside through the brush powder discharge hole (8) formed in the concave-convex portion at the opposite side of the rotor pole.

도 3(나)는 또다른 실시예의 본 발명 슬립링과 슬립링 가이드로써, 슬립링의 돌출부(11)상에 축과 직교방향으로 브러쉬 가루 배출공(8)을 형성한 것이다.3 (b) is a slip ring and slip ring guide according to another embodiment of the present invention, in which brush dust discharge holes 8 are formed on the protrusion 11 of the slip ring in a direction perpendicular to the axis.

따라서, 슬립링과 브러쉬의 마찰로 인하여 마모된 브러쉬는 브러쉬 가루를 방출하고, 이는 슬립링 가이드의 내주면을 따라 이송되어 슬립링의 돌출부에 형성된 브러쉬 가루 배출공(8)을 통해 외부로 배출되고, 이물질의 침투는 브러쉬 가루 배출공과 맞물려진 슬립링 가이드의 끝단에 의해 방지된다.Therefore, the brush worn due to the friction between the slip ring and the brush discharges the brush powder, which is transported along the inner circumferential surface of the slip ring guide and discharged to the outside through the brush powder discharge hole 8 formed in the protrusion of the slip ring, The ingress of foreign matter is prevented by the end of the slip ring guide engaged with the brush dust outlet.

도 3(다)는 슬립링의 돌출부와 맞물려지는 슬립링 가이드의 끝단에 브러쉬 가루 배출공(8)을 형성한 본 발명의 또 다른 실시예이다.3 (c) is another embodiment of the present invention in which a brush powder discharge hole 8 is formed at the end of the slip ring guide engaged with the protrusion of the slip ring.

발생된 브러쉬 가루는 슬립링 가이드의 끝단에 형성된 브러쉬 가루 배출공을 통해 슬립링의 돌출부를 따라 외부로 배출되고, 이물질은 슬립링 돌출부에 의해 침투가 방지된다.The generated brush powder is discharged to the outside along the protrusion of the slip ring through the brush powder discharge hole formed at the end of the slip ring guide, and foreign matter is prevented from penetrating by the slip ring protrusion.

도 3(라)는 슬립링 돌출부와 맞물려지는 슬립링 가이드 끝단 저면에 홈을 형성하여 브러쉬가루가 슬립링의 외부로 배출되도록 한 것이다.Figure 3 (d) is to form a groove in the bottom end of the slip ring guide that is engaged with the slip ring protrusion so that the brush powder is discharged to the outside of the slip ring.

이상에서 설명한 바와 같이 본 발명은 슬립링의 돌출부와 슬립링 가이드의 끝단이 맞물리는 부분에 홈 또는 통공을 형성하여 구심력에 의하여 침투되는 이물질을 방지함과 동시에 슬립링과 브러쉬의 마찰에 의한 브러쉬 가루가 슬립링 가이드 내부에 쌓여 접촉 불량을 일으키지 않도록 슬립링 가이드의 외부로 배출시키기 때문에 슬립링과 브러쉬의 접촉 불량을 개선하여 전류의 통전성을 향상키고, 따라서 발전기의 품질을 향상시킨 것이다.As described above, the present invention forms a groove or a hole in a portion where the protrusion of the slip ring and the end of the slip ring guide engage to prevent foreign substances from penetrating by centripetal force, and at the same time, brush powder caused by friction between the slip ring and the brush. Is discharged to the outside of the slip ring guide so as to accumulate inside the slip ring guide so as not to cause a poor contact, thereby improving contact current between the slip ring and the brush, thereby improving current conduction and thus improving the quality of the generator.
