Abstract

본 발명은 공기베어링을 사용한 VCR용 헤드 드럼 어셈블리에 관한 것이다.The present invention relates to a head drum assembly for a VCR using air bearings.

본 발명은 축과, 이 축에 회전가능하도록 고정설치되는 상부 드럼과, 그 상부 드럼에 맞대향하여 설치되며 그 내부에는 트랜스가 설치되어 있는 하부 드럼과, 상기 상부 드럼이나 하부 드럼의 내부 혹은 외부에 설치되며 모터를 구성하는 회전자 및 고정자와, 상기 상부 드럼의 회전을 원활하게 하기 위한 베어링을 구비하여 된 헤드 드럼 어셈블리에 있어서, 상기축의 양 단부에는 축 및 축에 고정된 회전체의 회전을 원활하게 하기 위한 베어링이 축에 연장되어 각각 마련되어 있다.The present invention provides a shaft, an upper drum which is fixedly rotatably mounted on the shaft, a lower drum which is installed to face the upper drum, and has a transformer installed therein, and inside or outside the upper drum or the lower drum. A head drum assembly comprising a rotor and a stator constituting a motor and a bearing for smoothly rotating the upper drum, wherein both ends of the shaft smoothly rotate the shaft and the rotor fixed to the shaft. Bearings are provided on the shaft, respectively.

이와 같은 본 발명은 베어링이 드럼의 외부에 마련되어 있으므로 종래 헤드 드럼에 있어서의 베어링 유니트가 드럼 내부에서 차지하던 공간을 대폭 감축시킬 수 있고, 그에 따라 헤드 드럼 어셈블리의 전체적인 크기를 소형화할 수 있다. 또한베어링 매커니즘을 축과 일체형으로 단순화시킴으로써 종래의 헤드 드럼에 있어서의 베어링 유니트의 조립상의 난점을 제거하여 제품의 생산성을 향상시킬 수 있다.Since the bearing is provided outside the drum, the present invention can greatly reduce the space occupied by the bearing unit in the conventional head drum, thereby miniaturizing the overall size of the head drum assembly. In addition, by simplifying the bearing mechanism integrally with the shaft, it is possible to eliminate the difficulty in assembling the bearing unit in the conventional head drum, thereby improving the productivity of the product.
