본 발명은 터닝센터 밀링 터렛의 베벨기어 윤활구조에 관한 것으로, 특히 윤활유가 밀링 터렛의 베벨기어의 치면에 항시 유지되도록 한 터닝센터 밀링 터렛의 베벨기어 윤활구조에 관한 것이다.The present invention relates to a bevel gear lubrication structure of a turning center milling turret, and more particularly, to a bevel gear lubrication structure of a turning center milling turret such that lubricating oil is always maintained on the tooth surface of the bevel gear of the milling turret.

CNC선반(터닝 센터 타입)의 밀링 터렛은 밀링 가공에 필요한 공구를 장착·구동시켜 필요한 밀링 가공을 가능하게 한다.The milling turret of the CNC lathe (turning center type) mounts and drives the tools necessary for milling, enabling the required milling.

도 1은 종래 터닝센터 밀링 터렛의 조립단면도를 나타낸 것으로, 스핀들 모터(12)에 의해 터렛헤드(6)에 장착되는 공구(T)를 회전 구동시키는 메카니즘을 나타내고 있다.FIG. 1 shows an assembly cross-sectional view of a conventional turning center milling turret, which shows a mechanism for rotationally driving a tool T mounted on the turret head 6 by a spindle motor 12.

즉, 스핀들모터(12)의 구동력이 타이밍 벨트(14)를 매개로 구동하우징(15)내의 구동샤프트(16)를 구동시키면, 구동샤프트(18)와 수직으로 배치된 클러치 샤프트(20)가 회전구동하게 되어 있다. 이때 클러치샤프트(20)는 한쌍의 베벨기어(22,24)의 이맞물림 회전을 매개로 구동샤프트(16)로부터 회전 동력을 전달받게 되어 있다.That is, when the driving force of the spindle motor 12 drives the drive shaft 16 in the drive housing 15 via the timing belt 14, the clutch shaft 20 disposed perpendicular to the drive shaft 18 rotates. It is to drive. At this time, the clutch shaft 20 receives the rotational power from the drive shaft 16 through the engagement rotation of the pair of bevel gears 22 and 24.

따라서 클러치 샤프트(20)에 연결되는 공구는 매 구동시마다 한쌍의 베벨기어(22,24)가 맞물려 회전하므로 윤활이 이루어져야 한다. 베벨기어(22,24)의 윤활 은 기어의 수명에 영향을 미치고 나아가 기계장비의 신뢰성을 좌우할 수 있기 때문이다.Therefore, the tool connected to the clutch shaft 20 should be lubricated because a pair of bevel gears 22 and 24 rotate in engagement with each drive. Lubrication of the bevel gears 22 and 24 can affect the life of the gear and further influence the reliability of the machine.

종래는, 베벨기어(22,24)의 치면에 점성이 큰 그리스(grease)를 바른 후 공구를 회전시키는 구조이다. 이때 그리스는 유동성이 크지 않아서 베벨기어(22,24)의 이맞물림 회전시 원심력에 의해 치면에서 이탈된다. 따라서 베벨기어(22,24)의 치면에는 부족한 윤활유에 의해 마찰력이 심화되고 마모가 진행되어 그 수명을 단축시키게 되었다. 베벨기어(22,24)의 단축 수명으로 인해 기계 장비의 신뢰도가 떨어짐은 물론이다.Conventionally, the tool is rotated after applying viscous grease to the tooth surfaces of the bevel gears 22 and 24. At this time, the grease is not large in fluidity and is separated from the tooth surface by centrifugal force during the engagement rotation of the bevel gears 22 and 24. Therefore, the bevel gears 22 and 24 have a high frictional force due to insufficient lubricating oil and wear progresses to shorten their lifespan. The short life of the bevel gears 22 and 24 reduces the reliability of the mechanical equipment.

따라서 본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위한 것으로, 밀링터렛에 설치된 베벨기어의 윤활구조를 개선하여 베벨기어의 수명 및 기계장비의 신뢰성을 향상시킬 수 있는 터닝센터 밀링 터렛의 베벨기어 윤활구조를 제공함에 그 목적이 있다.Therefore, the present invention is to solve the problems of the prior art as described above, bevel gear of the turning center milling turret that can improve the lubrication structure of the bevel gear installed in the milling turret to improve the life of the bevel gear and the reliability of the mechanical equipment The purpose is to provide a lubrication structure.

상기의 목적을 달성하기 위한 본 발명의 구체적인 수단은,Specific means of the present invention for achieving the above object,

밀링 터렛의 구동하우징내에 축설된 구동샤프트의 회전력을 한쌍의 구동측 베벨기어와 종동측 베벨기어를 통해 터렛헤드내에 회전지지된 클러치 샤프트로 전달하는 터닝센터 밀링 터렛의 동력전달장치에 있어서,In the power transmission device of the turning center milling turret which transmits the rotational force of the drive shaft built in the drive housing of the milling turret to the clutch shaft rotated and supported in the turret head through a pair of drive side bevel gears and driven side bevel gears.

상기 터렛헤드내에 배치되어 상기 클러치 샤프트와 종동측 베벨기어를 베어링을 매개로 회전지지함과 동시에 일정량의 윤활유가 충진되는 베어링 하우징과;A bearing housing disposed in the turret head to support the clutch shaft and the driven bevel gear through a bearing and to fill a predetermined amount of lubricant;

상기 베어링 하우징과 구동측 베벨기어의 사이에 개재되어 상기 베어링 하우징내의 윤활유가 상기 구동샤프트쪽으로 침입하는 것을 차단하는 내측 오일실과;An inner oil chamber interposed between the bearing housing and the driving side bevel gear to block the lubricating oil in the bearing housing from entering the driving shaft;

상기 구동측 베벨기어의 보스부 외주면과 상기 구동하우징의 선단면에 장착된 베어링 플랜지와의 사이에 개재된 외측 오일실이 포함된 것을 특징으로 한다.And an outer oil chamber interposed between the outer peripheral surface of the boss portion of the driving side bevel gear and the bearing flange mounted on the front end surface of the driving housing.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 밀링 터렛에 클러치 샤프트를 회전시키는 동력전달장치의 윤활유 구조를 나타낸 것이다.Figure 2 shows the lubricating oil structure of the power transmission device for rotating the clutch shaft in the milling turret according to the present invention.

도 2에서와 같이 밀링 터렛측 구동하우징(15)내에 축설된 구동샤프트(16)의 회전력을 한쌍의 구동측 베벨기어(22)와 종동측 베벨기어(24)를 통해 터렛헤드(6)내에 회전지지된 클러치 샤프트(20)로 전달하는 터닝센터 밀링 터렛의 동력전달장치에 있어서, 상기 터렛헤드(6)내에는 베어링 하우징(100)이 설치되어 있다.As shown in FIG. 2, the rotational force of the drive shaft 16 built in the milling turret side drive housing 15 is rotated in the turret head 6 through the pair of drive side bevel gears 22 and the driven side bevel gears 24. In the power transmission device of the turning center milling turret which is transmitted to the supported clutch shaft 20, a bearing housing 100 is provided in the turret head 6.

상기 베어링 하우징(100)은 상기 클러치 샤프트(20)와 종동측 베벨기어(24)를 베어링(140,142)을 매개로 회전지지함과 동시에 일정량의 윤활유가 충진되도록 되어 있다. 이때 사용되는 윤활유는 유동성이 큰 그리스가 될 수 있다. 충진된 윤활유의 유면 높이는 적어도 대략 L선상까지 될 수 있다.The bearing housing 100 rotates and supports the clutch shaft 20 and the driven bevel gear 24 via the bearings 140 and 142 and at the same time fills a predetermined amount of lubricant. The lubricating oil used at this time may be a highly fluid grease. The oil level of the filled lubricating oil can be at least approximately L-line.

상기 베어링 하우징(100)은 구동측 베벨기어(22)의 내주면에 위치하는 보스 부(102)가 포함되어 있고, 이 보스부(102)에는 내측 오일실(110)이 장착되어 있다.The bearing housing 100 includes a boss portion 102 positioned on an inner circumferential surface of the driving side bevel gear 22, and an inner oil chamber 110 is mounted to the boss portion 102.

상기 내측 오일실(110)은 단면이 대략 V자 형태로서 립부가 상기 종동측 베벨기어(22)에 접촉되어 있다. The inner oil chamber 110 is substantially V-shaped in cross section and has a lip contacting the driven side bevel gear 22.

따라서 내측 오일실(110)은 상기 베어링 하우징(100)과 구동측 베벨기어(22)의 사이에 개재되어 상기 베어링 하우징(100)내의 윤활유가 상기 구동샤프트(16)쪽으로 침입하는 것을 차단하게 된다.Therefore, the inner oil chamber 110 is interposed between the bearing housing 100 and the driving side bevel gear 22 to prevent the lubricant oil in the bearing housing 100 from entering the driving shaft 16.

상기 구동측 베벨기어(22)의 보스부 외주면과 상기 구동하우징(15)의 선단면에 장착된 베어링 플랜지(130)와의 사이에는 외측 오일실(120)이 개재되어 있다.An outer oil chamber 120 is interposed between the boss portion outer circumferential surface of the drive side bevel gear 22 and the bearing flange 130 mounted on the front end surface of the drive housing 15.

상기 외측 오일실(120)은 단면이 대략 V자 형태로서 립부가 상기 구동측 베벨기어(22)의 외주면에 접촉되어 있다. 따라서 외측 오일실(120)은 베벨기어(22,24)의 치면 바깥측으로 나온 윤활유가 구동측 베벨기어(22)를 지지하는 베어링(17)으로 칩입하는 것을 차단한다.The outer oil chamber 120 has a V-shaped cross section, and the lip portion is in contact with the outer circumferential surface of the driving side bevel gear 22. Accordingly, the outer oil chamber 120 prevents lubricating oil from the tooth surface outside of the bevel gears 22 and 24 from chipping into the bearing 17 supporting the driving side bevel gear 22.

한편, 상기 베어링 하우징(100)과 상기 종동축 베벨기어(24)의 보스부 외주면 사이에 개재되어 상기 베어링 하우징(100)내의 윤활유가 상기 종동축 베벨기어의 보스부로 누설되는 것을 차단하는 밀봉 베어링(140)이 구비된다.On the other hand, the sealing bearing is interposed between the bearing housing 100 and the boss outer peripheral surface of the driven shaft bevel gear 24 to block the lubricating oil in the bearing housing 100 from leaking to the boss portion of the driven shaft bevel gear ( 140 is provided.

이때 상기 종동측 베벨기어(24)를 회전지지하는 베어링(140)은 실 타입(seal type)으로 구성함으로서 윤활유의 누출을 방지할 수 있다.At this time, the bearing 140 for supporting the driven side bevel gear 24 is configured in a seal type to prevent the leakage of lubricating oil.

이와 같이 구성된 본 실시예의 작용을 설명한다.The operation of this embodiment configured as described above will be described.

먼저, 터렛헤드(6)내에 배치된 베어링 하우징(100)내에 일정량의 윤활유가 충진된다. 이때 충진되는 윤활유는 유동성이 큰 그리스를 사용하고, 충진된 유면의 높이는 대략 "L"위치까지 주입구(100a)를 통해 주입되고, 주입구(100a)는 나사결합된 플러그(150)에 의해 개폐가능하게 되어 있다.First, a certain amount of lubricant is filled in the bearing housing 100 arranged in the turret head 6. At this time, the lubricating oil to be filled uses a large flow grease, the filling oil level is injected through the injection hole (100a) up to approximately "L" position, the injection hole (100a) is opened and closed by a screwed plug 150 It is.

따라서 베벨기어(22,24)가 이맞물림하는 부분은 베어링 하우징(100)내에 충진된 윤활유에 잠기게 된다.Therefore, the portion where the bevel gears 22 and 24 engage is immersed in the lubricant filled in the bearing housing 100.

이 상태에서 구동원(스핀들모터)에 의해 구동샤프트(16)가 회전되면, 구동측 베벨기어(22)와 종동측 베벨기어(24)의 이맞물림을 통해 클러치샤프트(20)가 회전 구동한다. 이때 종동측 베벨기어(24)의 치면은 항시 윤활유내에서 잠긴 상태에서 회전하고, 구동측 베벨기어(22)의 치면도 윤활유를 매회전마다 거치게 되므로 치합면에 항시 윤활유가 공급되게 되어 치면의 마모 및 파손을 방지하게 된다.When the drive shaft 16 is rotated by the drive source (spindle motor) in this state, the clutch shaft 20 is driven to rotate by engaging the drive side bevel gear 22 and the driven side bevel gear 24. At this time, the tooth surface of the driven side bevel gear 24 is always rotated in the lubricating oil, and the tooth surface of the driving side bevel gear 22 also passes through the lubricating oil every turn, so that the lubricating oil is always supplied to the mating surface and the wear of the tooth surface And breakage.

한편, 베벨기어(22,24)의 치합면을 빠져나오는 윤활유는 실타입 베어링(140)과 오일실(120)에 의해 차단되어 외부로 누유되는 것을 방지하게 된다.On the other hand, the lubricating oil exiting the mating surfaces of the bevel gears 22 and 24 is blocked by the seal-type bearing 140 and the oil chamber 120 to prevent leakage to the outside.

또한 베어링 하우징(100)의 보스부(102)에 장착된 오일실(110)에 의해 윤활유가 구동샤프트(16)로 누유되는 것도 방지하게 된다.In addition, the oil seal 110 mounted on the boss portion 102 of the bearing housing 100 prevents the lubricant from leaking to the driving shaft 16.

이상과 같이, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능함은 물론이다.As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.

상술한 바와 같이 본 발명의 터닝센터 밀링 터렛의 베벨기어 윤활구조에 따르면, 터렛 헤드 내에 윤활유를 충진하는 베어링 하우징을 설치하고, 이 베어링 하 우징에서 이맞물림하는 한쌍의 베벨기어의 주변으로 누유를 방지하는 실링장치를 설치함으로서 한쌍의 베벨기어의 치합면이 항시 윤활유에 접촉되어 동작되므로 기어의 수명이 연장되고, 이로 인해 공작기계 장비의 신뢰성을 향상시킬 수 있다.As described above, according to the bevel gear lubrication structure of the turning center milling turret of the present invention, a bearing housing for filling lubricating oil is installed in the turret head, and leakage is prevented around the pair of bevel gears engaged with the bearing housing.
