본 고안은 VTR 드럼에 형성되어 있는 모터를 보호하는 모터 보호 커버의 고정장치를 개량한 것이다.The present invention is an improvement of the fixing device of the motor protective cover for protecting the motor formed in the VTR drum.
주지된 바와 같이 VTR의 드럼은 제 1 도에서 표시된것처럼, 회전되는 상부드럼과 드럼베이스에 고정되는 하부드럼으로 구성되어 있으며 하부드럼의 하단에는 스테이터(stator)가 고정설치되고 드럼샤프트에는 스테이터를 감싸는 형태로 로터(Rotor)가 설치되어서 드럼을 회전시키는 모터를 구성하고 있으며 드럼샤프트의 상단에는 어스브라켓이 설치되어 있다.As is well known, the drum of the VTR is composed of a rotating upper drum and a lower drum fixed to the drum base, as shown in FIG. 1, and a stator is fixed to the bottom of the lower drum and a stator is wrapped around the drum shaft. A rotor is installed in the form to form a motor for rotating the drum, and an earth bracket is installed on the top of the drum shaft.
또한 이와 같은 모터 부분을 보호하기위한 보호커버는 하측이 개구된 형태로서 하부드럼에 나사로서 고정설치되어 있으며, 로터의 둘레를 감싸고 있는 형태이다.In addition, the protective cover for protecting such a motor portion is a form in which the lower side is fixed to the lower drum as a screw and is wrapped around the rotor.
따라서 이와 같은 종래 기술에서는 고속회전하는 드럼의 진동을 감쇄시킬수 있는 어떠한 구조도 없으며 모터의 분해 조립이 어려우며, 어스브라켓을 별도로 드럼 샤프트 상단에 설치하여 접지 지켜야 하는등의 문제점이 있었다.Therefore, in the prior art as described above, there is no structure that can attenuate the vibration of the drum rotating at high speed, disassembly and assembly of the motor is difficult, and there is a problem that the earth bracket must be separately installed on the top of the drum shaft to keep the ground.
본 고안에서는 종래 기술에서 모터 보호커버를 고정설치하는 방법을 개선하므로서 드럼의 진동을 감쇄시키고, 모터의 분해 조립이 용이하게하며, 모터 부위에 먼지등이 침입되는 것을 방지하고, 상단부의 어스브라켓도 제거할수 있게 하였는데, 이와 같은 목적을 달성하기 위한 기술 수단으로는 첫째 : 하부가 밀폐된 모터 보호커버를 사용하며, 둘째 : 모터 보호 커버를 나사로 체결하지 않고 하부드럼과 드럼베이스 사이에 끼워 압착시키는 기술수단을 강구하였다.The present invention improves the method of fixing and installing the motor protective cover in the prior art to reduce the vibration of the drum, to facilitate the disassembly and assembly of the motor, to prevent the intrusion of dust, etc. in the motor portion, the earth bracket at the top As a technical means to achieve the above object, firstly, the motor cover is closed and the motor cover is closed. Second, the motor protection cover is screwed between the lower drum and the drum base without screwing. Sudan was devised.
이하 본 고안을 첨부도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제 2 도에서 보면 도면부호 (1)과 (2)는 상부드럼과 하부드럼인데 하부드럼(2)의 하측끝단에는 스테이터(6)가 고정설치되고 샤프트(3)에는 로터(5)가 설치되어 스테이터(6)를 감싸고 있음을 알 수 있다.In FIG. 2, reference numerals 1 and 2 are upper drums and lower drums, and a stator 6 is fixedly installed at the lower end of the lower drum 2 and a rotor 5 is installed at the shaft 3. It can be seen that it surrounds the stator 6.
또한 모터 보호러버(4)는 밑면이 밀폐된 형태이며, 하부드럼(2)의 저면에 패킹링(9)을 끼우고 그위에 접하고 있으며, 고정은 드럼베이스(7)와 하부드럼(2)을 나사체결하므로 그 사이에서 고정됨을 알 수 있다.In addition, the motor protection rubber (4) is in the form of a closed bottom, the packing ring (9) is fitted on the bottom of the lower drum (2) and abuts thereon, and fixing the drum base (7) and the lower drum (2) Since it is screwed in, it can be seen that it is fixed in between.
그리고 어스브라켓(8)은 모터 보호커버(4)의 하부 중앙에서 드럼샤프트(3)와 접촉할수 있게 설치되어 있다.And the earth bracket 8 is installed to be in contact with the drum shaft 3 in the lower center of the motor protective cover (4).
이와 같이 구성된 본 고안에서는 고속으로 회전하는 드럼의 진동이 하부드럼(2)과 모터보호러버(4) 사이에 설치되어 있는 패킹(9)에 의하여 감쇄되므로 미세한 진동과 소음이 감소하는 효과가 있으며, 모터 보호커버(4)는 모터 부분을 완전 밀폐시키므로 먼지등이 모터에 부착되는 것을 방지하여 성능이 저하 되는 것을 방지한다.In the present invention configured as described above, the vibration of the drum rotating at high speed is attenuated by the packing 9 installed between the lower drum 2 and the motor protection rubber 4, so that the vibration and noise are reduced. The motor protective cover 4 completely seals the motor part, thereby preventing dust from being attached to the motor, thereby preventing performance degradation.
또한 모터 보호커버(4)는 하부드럼(2)과 드럼베이스(7) 사이에 끼워저 눌려서 고정되므로 종전처럼 취부용나사가 불필요하여 조립공정이 단축되며 모터의 분해 조립도 용이하다. 그리고 어스브라켓(8)을 모터 보호커버에 설치하므로서 어스 브라켓(8)을 설치하기 위한 별도이 부품이 줄어들 수 있는 특징이 있다.In addition, since the motor protective cover 4 is inserted and pressed between the lower drum 2 and the drum base 7, the mounting screw is unnecessary as before, so that the assembly process is shortened and the assembly and disassembly of the motor is easy. And by installing the earth bracket (8) to the motor protective cover has a feature that can be additionally reduced parts for installing the earth bracket (8).
