본 고안은 스핀들 모터에 사용된 메탈 베어링의 오일 비산 방지 구조를 가진 모터에 대한 것이다.The present invention is directed to a motor having an oil splash preventing structure of a metal bearing used in a spindle motor.

일반적으로 플로피 디스크 드라이브라든지 CD-ROM 드라이브에는 스핀들 모터가 주로 사용되고, 이러한 스핀들 모터에는 메탈 베어링이 많이 사용되고 있다.In general, a spindle motor is mainly used for a floppy disk drive or a CD-ROM drive, and metal bearings are frequently used for such a spindle motor.

제3도 도면에서 보듯이 베이스 플레이트(a)상에 고정하되, 고정자(b)가 결합된 하우징(c), 상기한 하우징(c)의 중앙에 축착된 회전축(d), 상기한 회전축(d)의 상단에서 부시(e)로 결합되고, 내주면에 마그네트(f)가 부착된 회전자(g)로 모터가 구성된다.3 is fixed on the base plate (a), the housing (c) to which the stator (b) is coupled, the rotating shaft (d) condensed in the center of the housing (c), the rotating shaft (d The motor is composed of a rotor (g) coupled to the bush (e) at the top of the), the magnet (f) is attached to the inner peripheral surface.

이때 상기한 회전축(d)과 하우징(c)의 사이에 메탈 베어링(h)이 개입되는 바, 다음과 같은 문제점이 있다.At this time, the metal bearing (h) is interposed between the rotating shaft (d) and the housing (c), there are the following problems.

즉, 모터가 고속 회전을 하게 되면 메탈 베어링(h)에서는 윤활작용을 위해 오일이 뿜어져 나와 회전축(d)과의 사이에 도포되는 바, 이때 오일에도 원심력이 작용하기 때문에 상측은 물론 바깥쪽으로 비산되어 플로피 디스크를 손상시킬 염려가 있다.In other words, when the motor rotates at a high speed, oil is spouted from the metal bearing (h) for lubrication and is applied between the rotating shaft (d). This can damage the floppy disk.

따라서 본 고안은 상기와 같은 종래의 여러 가지 문제점을 해결하기 위해 안출한 것으로 고안의 주된 목적은 메탈 베어링에서 비산되는 오일을 외부로 퍼져나가지 못하도록 차단하고자 하는데 있으며, 더 나가서 제품의 손상을 방지하고자 하는 것이다.Therefore, the present invention has been devised to solve various problems as described above, and the main purpose of the present invention is to block oil from the metal bearings from spreading to the outside, and to prevent further damage to the product. will be.

그리고 이를 위한 주요 구성은 베이스 플레이트상에서 외주면에 고정자가 결합된 하우징과, 상기한 하우징의 중앙에 축착된 회전축과, 상기한 회전축의 상단에서 부시로 결합된 채 내주면에 마그네트가 부착된 회전자로 이루어진 스핀들 모터에 있어서, 상기한 부시의 저면에 나팔모양으로 이루어진 유도원판을 구비하여 오일이 비산되지 못하도록 차단하는데 있다.And the main configuration for this is composed of a housing having a stator coupled to the outer circumferential surface on the base plate, a rotary shaft condensed in the center of the housing, and a magnet attached to the inner circumferential surface while being coupled by a bush at the upper end of the rotating shaft In the spindle motor, the bottom surface of the bush is provided with a trumpet-shaped induction disc to block oil from scattering.

이하 첨부 도면에 따라 본 고안의 구성 및 작용 효과를 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation of the present invention in detail according to the accompanying drawings.

제1도는 본 고안의 부시를 사용한 상태의 모터 단면도이고, 제2도는 본 고안의 작용상태를 보인 요부 확대 단면도이다.1 is a cross-sectional view of the motor using the bush of the present invention, Figure 2 is an enlarged cross-sectional view of the main portion showing an operating state of the present invention.

베이스 플레이트(1)의 위에 하우징(2)이 입설되어 있고, 이 하우징의 외주면에는 고정자(3)가 결합되어 있다.The housing 2 is mounted on the base plate 1, and the stator 3 is coupled to the outer circumferential surface of the housing.

또한 하우징(2)의 중앙에는 메탈 베어링(4)이 상,하로 끼워져 회전축(5)을 지지하고 있고, 회전축(5)의 상단에는 내주면에 마그네트(7)를 가진 회전자(6)가 부시(8)를 이용해 축착되어 있다.In addition, the metal bearing 4 is inserted up and down in the center of the housing 2 to support the rotating shaft 5, and the upper end of the rotating shaft 5 has a rotor 6 having a magnet 7 on its inner circumferential surface. It is condensed using 8).

이때, 본 고안에서는 상기한 부시(8)의 저면에 일체로 형성된 유도원판(81)을 마련한 것이 특징이다.At this time, the present invention is characterized in that the induction disc 81 formed integrally on the bottom of the bush (8).

유도원판(81)은 부시(8)의 저면에서 연장 형성하되, 위가 좁고 아래가 넓은 나팔모양이며, 그 끝단은 윗쪽 메탈 베어링(4)에 근접하도록 한 것이다.The induction disc 81 extends from the bottom of the bush 8, but is narrow in shape and wide in the shape of a trumpet at the bottom, and the end thereof is close to the upper metal bearing 4.

다음은 상기와 같이 구성된 본 고안의 작동상태에 대해서 설명한다.The following describes the operating state of the present invention configured as described above.

부시(8)에서 일체로 형성한 유도원판(81)을 메탈 베어링(4)의 상면에 근접시킴으로써 원심력에 의해 올라가던 오일은 제2도의 화살표와 같이 유도원판(81)의 내저면에 부딪혀 다시 아래로 떨어지게 되고, 유도원판(81)의 윗쪽에서는 공기가 바깥쪽으로 흘러서 비산되어 올라오는 오일을 다시 아래쪽으로 떨어지도록 유도하는 것이다.The oil which has been raised by centrifugal force by bringing the induction disk 81 integrally formed from the bush 8 close to the upper surface of the metal bearing 4 hits the inner bottom surface of the induction disk 81 again as shown by the arrow of FIG. To fall to, the upper side of the induction disc 81 is to induce the air flows outward to fall back to the oil coming up.

이상에서 자세히 설명한 바와 같이 본 고안은 메탈 베어링을 사용하는 스핀들 모터에 있어서, 회전자에 결합되는 부시(8)가 오일 차단용 유도원판(81)을 가지도록 개량하였기 때문에 오일이 디스크 등으로 퍼지지 않아 손상시킬 염려가 없고 오일이 쉽게 손실되지 않으므로 베어링의 수명을 연장시키게 되는 것이다.As described in detail above, in the present invention, in the spindle motor using a metal bearing, since the bush 8 coupled to the rotor is improved to have an oil blocking induction disk 81, the oil does not spread to the disk or the like. There is no risk of damage and oil is not easily lost, extending the life of the bearing.
