Abstract
부품수가 절약되고 조립 공수가 감소하도록 그 구조가 개량된 테이프 레코더의 헤드드럼에 관하여 개시한다. 이 헤드드럼은, 샤프트(10)와, 샤프트(10)에 압입 고정되는 상부 드럼(12)과, 상부 드럼(12)과 맞대향하여 설치되는 하부 드럼(18)과, 하부 드럼(18)의 외부에 설치되며 모터를 구성하는 로터(24) 및 스테이터(25)와, 내륜이 샤프트(10)에 고정되어 회전하는 복수개의 베어링(16)과, 모터의 로터(24)에 몰딩 고정되고, 상기 베어링(16)을 예압 가능하도록 상기 베어링(16)하부에 위치하는 탄성 부재로 된 모터부시(30)를 구비한다. 이와 같은 테이프 레코더의 헤드드럼은 부시 기능과 댐핑 기능을 하는 부품을 일체로 성형함으로써, 종래에 비하여 부품수가 감소되고 작업공수가 줄어들어, 제품 생산성이 향상된다는 이점이 있다.A head drum of a tape recorder in which the structure is improved such that the number of components is reduced and the number of assembling steps is reduced. The head drum includes a shaft 10, an upper drum 12 press-fitted into the shaft 10, a lower drum 18 disposed opposite to the upper drum 12, A rotor 24 and a stator 25 constituting a motor and a plurality of bearings 16 whose inner ring is fixed to the shaft 10 and are rotated and fixed to the rotor 24 of the motor, And a motor bush (30) made of an elastic member positioned under the bearing (16) so as to be preloaded on the bearing (16). The head drum of such a tape recorder is advantageous in that the number of components is reduced and the number of working operations is reduced by forming the parts having the bushing function and the damping function integrally as compared with the conventional one.
