본 고안은 브이씨알의 회전드럼 조립체에 관한 것으로, 특히 분해 및 조립이 용이하고 분해시 베어링이 손상되지 않도록 하여 재사용이 가능하게한 회전드럼 조립체에 관한 것이다.The present invention relates to a rotating drum assembly of V-Cal, and more particularly, to a rotating drum assembly that is easy to disassemble and assemble and that the bearing is not damaged during disassembly, thereby enabling reuse.

종래 자기기록재생장치의 회전드럼 조립체는 제 1 도에 도시한 바와같이, 회전상드럼(1), 고정하드럼(2), 플랜지(3), 모터스테이터(4), 모터로터(5) 및 샤트프(6)등으로 구성된다.As shown in FIG. 1, the rotating drum assembly of the conventional magnetic recording and reproducing apparatus includes a rotating drum 1, a fixed drum 2, a flange 3, a motor stator 4, a motor rotor 5 and It consists of the shaft 6, etc.

상기 플랜지(3)에는 샤프트(6)가 압입되고 또 플랜지(3)와 고정하드럼(2)에 트랜스로터(7)와 트랜스 스테이터(8)가 접착되며, 샤프트(6)는 고정하드럼(2)에 고정되어 있는 상하베어링(9)의 내륜(10)에 입설되어 있다.A shaft 6 is press-fitted to the flange 3, and a trans rotor 7 and a trans stator 8 are bonded to the flange 3 and the fixed drum 2, and the shaft 6 is fixed to the fixed drum ( It is installed in the inner ring 10 of the up-and-down bearing 9 fixed to 2).

회전드럼 조립체 조립시에 상기 플랜지(3)에 명성된 돌기(3a)는 상측 베어링(9)의 내륜에, 링컬러(11)에 형성된 돌기(11a)는 하측 베어링(9)의 내륜에 접촉시키고 예압을 준 상태에서 스크류(12)로 샤프트(6)와 링컬러(11)를 고정하며 링칼러(11)에는 모터 로터(5)를 나사(13)로 체결한다.When assembling the rotating drum assembly, the projection 3a, which is well known on the flange 3, contacts the inner ring of the upper bearing 9, and the projection 11a formed on the ring color 11 makes contact with the inner ring of the lower bearing 9. The shaft 6 and the ring color 11 are fixed with the screw 12 in the preloaded state, and the motor rotor 5 is fastened to the ring color 11 with the screw 13.

상기 샤프트(6)의 직경과 베어링 내륜(10)의 내경은 수 ㎛으로 조합되어 조립되므로, 조립후에 하드럼(2)과 샤프트(6), 플랜지(3)를 분해할 때에 스크류(12)에 의해 샤프트(6)에 발생한 스크래치 또는 버(burr)가 베어링(9)의 내륜(10) 내면에 손상을 주어 재조립시 그와같이 손상된 베어링(9)에 의해 지터, 와우플러터가 악화되고 이에따라 영상신호의 화질이 나쁘게 되었으며 이러한 문제점으로 인하여 샤프트(6)와 링컬러(11)를 한번 조립하면 분해하여 재사용할 수 없게 되었다.Since the diameter of the shaft 6 and the inner diameter of the bearing inner ring 10 are assembled in a combination of several micrometers, the screw 12 is used to disassemble the hard rum 2, the shaft 6, and the flange 3 after assembly. As a result, scratches or burrs generated on the shaft 6 damage the inner surface of the inner ring 10 of the bearing 9 so that the jitter and the wow flutter worsen by the damaged bearing 9 when reassembled. The image quality of the signal is deteriorated and due to this problem, once the shaft 6 and the ring color 11 are assembled, they cannot be disassembled and reused.

상기한 회전드럼 조립체는 모터 스테이터(4)와 모터로터(5)의 상호작용에 의해 전기적 에너지를 기계적 에너지로 바꾸어 모터로터(5)를 회전시키고 따라서 링칼러(11), 샤프트(6), 플랜지(3) 및 상드럼(1)을 회전시킨다.The rotating drum assembly rotates the motor rotor 5 by converting electrical energy into mechanical energy by the interaction of the motor stator 4 and the motor rotor 5, and thus the ring collar 11, shaft 6, flange. (3) and the upper drum 1 are rotated.

이때 상드럼(1)에 부착된 비디오 헤드(14)가 상드럼(1)의 외주면에 접촉주행하는 비디오 테이프(T)에 영상신호를 기록 또는 재생한다.At this time, the video head 14 attached to the drum 1 records or reproduces the video signal on the video tape T which is in contact with the outer peripheral surface of the drum 1.

이와같이 작동할때에 상기 샤프트(6)가 분해되어 재사용된 것인 경우에는 앞에서 언급한 바와같이 스크류(12)의 체결부분에 생긴 스크래치 또는 버에 의하여 베어링(9)의 내륜(10)에 스크래치 또는 버가 생겨 손상되어 있으므로 샤프트(6)와 베어링 내륜(10)과의 조립이 정확하지 못하여 화질이 불량하게 되는 것이었다.If the shaft 6 is disassembled and reused during operation, scratches or burrs on the inner ring 10 of the bearing 9 may be caused by scratches or burrs formed on the fastening portion of the screw 12 as mentioned above. Since the burrs were damaged due to the burrs, the assembly of the shaft 6 and the bearing inner ring 10 was not accurate, resulting in poor image quality.

결국 종래의 회전드럼 조립체는 샤프트와 링컬러를 스크류로 체결하여 그 체결부분에 홈이 생기므로 일단 조립된 후에는 분해하여 재사용할 수 없게되는 결함과 조립 및 분해도 어려운 결함이 있었다.As a result, the conventional rotating drum assembly has a defect in the fastening of the shaft and the ring color with a screw, so that a groove is formed in the fastening portion, and thus, the assembly and disassembly are difficult to disassemble and reuse once assembled.

본 고안은 이와같은 종래의 결함을 해소하기 위하여 안출한 것으로, 고정하드럼에 압입고정된 상하 베어링에 고정되는 샤프트의 하측부에 샤프트의 직경보다 작은 직경을 가지는 체결부를 단차지게 형성함과 아울러 링컬러의 중앙안내공 상단부에는그 중앙안내공 보다 큰 직경을 가지는 안내면을 단차지게 형성함과 아울러 링컬러의중앙안내공 상단부에는 그 중앙안내공보다 큰 직경을 가지는 안내면을 단차지게 형성하고 상기 샤프트의 체결부를 고정하게 함으로써, 스크류에 의하여 샤프트에 생긴 흠집 때문에 회전드럼 조립체를 분해할때에 베어링의 내륜에 스크래치나 버등의 흠이 생기게 되는 결함을 방지할 수 있게하여 베어링의 재사용이 가능하게한 것인바, 이를 첨부한 도면에 따라 상세히 설명하면 다음과 같다.The present invention is devised to solve such a conventional defect, the step of forming a fastening part having a diameter smaller than the diameter of the shaft at the lower side of the shaft fixed to the upper and lower bearings fixed to the fixed drum by the ring On the upper end of the central guide hole of the color to form a guide surface having a diameter larger than the central guide hole, and at the upper end of the central guide hole of the ring color to form a guide surface having a diameter larger than the central guide hole to step By fixing the fastening part, it is possible to prevent the defects such as scratches or burrs on the inner ring of the bearing when the rotating drum assembly is dismantled due to the scratches on the shaft caused by the screw. This will be described in detail with reference to the accompanying drawings.

제 2 도 및 제 3 도에 도시한 바와같이 회전상드럼(1)과 고정하드럼(2)이 구비되고, 고정하드럼(2)에 상하측 베어링(9)이 압입고정되며 상하측 베어링(9)에 고정된 샤프트(6)의 상측부에는 돌기(3a)를 가지는 플랜지(3)가 고정되고 그 상측에 회전상드럼(1)이 고정됨과 아울러 샤프트(6)의 하측부에는 돌기(11a)가 상단부에 형성되고 중앙안내공(11b)에서 체결공(11c)이 직교되게 형성된 링컬러(11)가 스크류(12)로 고정되며, 고정하드럼(2)가 링컬러(11)에는 모터 스테이너(4)와 모터로터(5)가 고정된 회전드럼 조립체에 있어서, 상기 샤프트(6)의 하측부에 그 샤프트(6)의 직경보다 작은 직경을 가지는 체결부(6a)를 단차지게 형성하고, 상기 링컬러(11)의 안내공(11b) 상단부에는 그 안내공(11b)보다 큰 직경을 가지는 안내면(11d)을 형성함과 아울러 그에게 경사안내면(11e)을 이어서 형성하며, 상기 샤프트(6)의 체결부(6a)를 링컬러(11)의 중앙 안내공(11b)에 삽입하여 샤프트(6)의 단턱부(6b)가 링컬러(11)의 단턱부(11f)에 걸리게 하고 체결공(11c)에 나사맞춤되는 스크류(12)로 상기 샤프트(6)의 체결부(6a)를 고정하여서 된 것으로, 상기 링컬러(11)의 안내공(11b)의 직경은 샤프트(6)의 체결부(6a)의 직경보다 약간 크게 형성된다.As shown in FIGS. 2 and 3, the rotary upper drum 1 and the fixed drum 2 are provided, and the upper and lower bearings 9 are press-fitted and fixed to the fixed drum 2, and the upper and lower bearings ( The flange 3 having the projection 3a is fixed to the upper side of the shaft 6 fixed to 9), and the rotary upper drum 1 is fixed to the upper side thereof, and the projection 11a is disposed below the shaft 6. ) Is formed at the upper end, and the ring color 11 formed with the fastening holes 11c at right angles in the center guide hole 11b is fixed with a screw 12, and the fixed drum 2 is connected to the ring color 11 with a motor. In the rotary drum assembly, in which the stator 4 and the motor rotor 5 are fixed, a fastening portion 6a having a diameter smaller than the diameter of the shaft 6 is formed at the lower side of the shaft 6. At the upper end of the guide hole 11b of the ring color 11, a guide surface 11d having a diameter larger than that of the guide hole 11b is formed, and an inclined guide surface 11e is attached thereto. And the fastening part 6a of the shaft 6 is inserted into the center guide hole 11b of the ring color 11 so that the stepped part 6b of the shaft 6 is the stepped part of the ring color 11. The fastening portion 6a of the shaft 6 is fixed by a screw 12 which is caught by 11f and is screwed into the fastening hole 11c, so that the guide hole 11b of the ring color 11 is fixed. The diameter is formed slightly larger than the diameter of the fastening portion 6a of the shaft 6.

이와같이된 회전드럼 조립체는 샤프트(6)의 하측부에 체결부(6a)가 단차지게 형성되고 링컬러(11)의 중앙안내공(11b) 상측부에는 안내면(11d)과 경사안내면(11e)이 형성되어 샤프트(6)의 단턱부(6b)가 링컬러(11)의 단턱부(11f)에 걸림상태로 샤프트(6)의 체결부(6a)가 링컬러(11)의 중앙안내공(11b)에 삽입되어 링컬러(11)의 체결공(11c)에 체결되는 스크류(12)가 샤프트(6)의 체결부(6a)를 고정하도록 되어 있으므로 그 스크류(12)에 의하여 샤프트(6)의 체결부(6a)에 생기는 흠집으로 인하여 회전드럼 조립체 분해시에 베어링(9)의 내륜(10) 내주면에 스크래치나 버드의 흠이 생기는 문제점이 발생하지 않게된다.The rotating drum assembly has a fastening portion 6a formed at the lower side of the shaft 6, and a guide surface 11d and an inclined guide surface 11e are formed on the upper portion of the central guide hole 11b of the ring color 11. And the fastening portion 6a of the shaft 6 is the central guide hole 11b of the ring color 11 with the stepped portion 6b of the shaft 6 being locked to the stepped portion 11f of the ring color 11. The screw 12, which is inserted into the fastening hole 11c of the ring color 11, is fixed to the fastening portion 6a of the shaft 6 so that the screw 12 of the shaft 6 Scratches in the fastening part 6a do not cause a problem of scratches or buds on the inner circumferential surface of the inner ring 10 of the bearing 9 when the rotating drum assembly is disassembled.

따라서 분해작업이 훨씬 용이하게 되며, 베어링(9)의 내륜(10) 및 샤프트(6)의 동체가 손상되지 않기 때문에 그 베어링(9)이나 샤프트(10)를 재사용하여 조립할 때에도 조립을 쉽게할 수 있으며 조립된 회전드럼 조립체의 성능이 저하되는 문제점이 배제된다.Therefore, the disassembly operation is much easier, and since the inner ring 10 of the bearing 9 and the body of the shaft 6 are not damaged, the assembling can be easily performed when the bearing 9 or the shaft 10 is reused and assembled. And the problem that the performance of the assembled rotating drum assembly is excluded.
