본 발명은 VTR 데크의 헤드드럼에 관한 것으로, 드럼모터에 연결된 회전축에 일체로 예압보스를 구성하여, 그 예압보스가 드럼의 상하부 베어링에 일정한 압력을 가하도록 구성된 것에 있어서, 예압보스에 본드주입구를 형성하고, 그 본드주입구에 본드를 삽입하여 회전축에 고정시킴으로써, 조립부품의 감소로 비용이 절감되며, 조립을 간편하게 하여 생산성이 향상되도록 한 것을 특징으로 하는 VTR 드럼의 예압보스에 관한 것이다.The present invention relates to a head drum of a VTR deck. The preload boss is integrally formed with a rotating shaft connected to a drum motor, and the preload boss is configured to apply a constant pressure to the upper and lower bearings of the drum. The present invention relates to a preload boss of a VTR drum, which is formed, and a bond is inserted into the bond inlet and fixed to a rotating shaft, thereby reducing costs by reducing assembly parts, and simplifying assembly to improve productivity.
일반적으로 VTR의 헤드 드럼은 드럼모터와 일체로 회전하도록 회전축이 구비되어 있으며, 그 회전축의 회전을 받아 드럼의 일정한 회전을 하여 테이프를 읽어 내도록 하고 있다. 이때 드럼의 상하부에 베어링을 형성하고, 하부베어링의 밑에 예압보스를 구비하여, 그 예압보스가 하부베어링에 일정한 힘으로 예압을 가하도록 하여 드럼이 회전할 때 상하부 베어링이 무리한 힘을 받지 않도록 하고 있었다.In general, the head drum of the VTR is provided with a rotating shaft so as to rotate integrally with the drum motor, and the drum is subjected to constant rotation of the drum to read the tape. At this time, bearings were formed in the upper and lower parts of the drum, and a preload boss was provided under the lower bearing so that the preload boss applied a preload to the lower bearing with a constant force to prevent the upper and lower bearings from being subjected to excessive force when the drum rotates. .
종래에는 제1도에 도시한 바와같이 회전축(1)에 상부드럼(2a)와 하부드럼(2)이 결합되어 있고, 그 하부드럼(2)의 상하부에는 상부베어링(3a)과 하부베어링(3)을 장착하였으며, 그 하부베어링(3)의 밑에는 스프링와샤(6)를 사이에 두고서, 예압을 하부베어링(3)에 가하는 예압보스(4)가 스크루(5)을 이용하여 회전축(1)에 고정설치됨으로써, 드럼이 회전할 때 예압보스(4)에 의해 드럼의 상하부에 구성된 베어링(3)(3a)이 무리한 힘을 받지 않도록 하였다.Conventionally, as shown in FIG. 1, the upper drum 2a and the lower drum 2 are coupled to the rotating shaft 1, and the upper and lower parts of the lower drum 2 are upper and lower bearings 3a and 3, respectively. ), And a preload boss (4) for applying a preload to the lower bearing (3) with a spring washer (6) between the lower bearing (3) and the rotating shaft (1) using a screw (5). By being fixed to the shaft, the bearings 3 and 3a formed on the upper and lower parts of the drum by the preload boss 4 are not subjected to excessive force when the drum rotates.
그러나 종래 예압보스(4)에 의해서는 스크루(5)를 이용하여 회전축(1)에 고정되기 때문에 스크루(5)의 조임이 풀리어지면, 하부베어링(3)과 스프링 와샤(6)에 압력을 가하고 있는 예압보스(4)가 그 기능인 예압을 지속적으로 하부베어링(3)에 가하기 어렵고, 조립공정에서는 하부베어링(3)에 예압을 가한 후에 예압보스(4)를 스크루(6)에 의해 조여 회전축(1)에 고정시켜야 하기 때문에 조립공정상의 어려움이 있었으며, 작업속도가 느려 생산성 향상에 문제가 있었다.However, since the conventional preload boss 4 is fixed to the rotating shaft 1 using the screw 5, when the screw 5 is tightened, the pressure is applied to the lower bearing 3 and the spring washer 6. It is difficult for the preloading boss 4 to be applied to continuously apply the preloading function to the lower bearing 3, and in the assembling process, the preloading boss 4 is tightened by the screw 6 after the preloading is applied to the lower bearing 3. Since it had to be fixed to (1), there was a difficulty in the assembly process, and there was a problem in improving productivity due to the slow working speed.
따라서 본 발명은 상기와 같은 문제점을 감안하여 예압보스가 본드에 의해 회전축에 결합되도록 하여 베어링이 무리한 힘을 받지 않도록 하며, 조립이 간단하고, 조립공정을 단축시켜 생산성을 향상시키는 목적이 있었다.Therefore, in view of the above problems, the present invention has a purpose of preventing the bearing from being subjected to excessive force by allowing the preload boss to be coupled to the rotating shaft by a bond, and the assembly is simple, and the assembly process is shortened to improve productivity.
이와같은 목적을 가진 본 발명은 드럼모터에 연결된 회전축에 일체로 예압보스를 구성하여, 그 예압보스가 드럼의 상하부 베어링에 일정한 압력을 가하도록 구성된 것에 있어서, 그 예압보스에 본드주입구를 형성하고, 본드주입구에 본드를 삽입하여 회전축에 고정시킴으로써 조립부품의 감소로 비용이 절감되며, 조립을 간편하게 하여 생산성이 향상되도록 함으로써 본 발명의 소기의 목적을 달성하도록 안출한 것이다.The present invention having the above object constitutes a preload boss integrally with the rotating shaft connected to the drum motor, and the preload boss is configured to apply a constant pressure to the upper and lower bearings of the drum, thereby forming a bond inlet to the preload boss, By inserting the bond in the bond inlet and fixed to the rotary shaft, the cost is reduced by the reduction of assembly parts, and the assembly is made to achieve the desired object of the present invention by simplifying the assembly to improve productivity.
이하 본 발명의 구성을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.
제2도 내지 제4도에 도시한 바와 같이 본 발명은 드럼모터에 연결된 회전축(11)에 일체로 예압보스(14)를 결합 구성하여, 그 예압보스(14)가 하부드럼(12)의 상하부 베어링(13)(13a)에 일정한 압력을 가하도록 구성된 것은 종래와 동일하지만, 본 발명에 있어서 특이한 것은, 그 예압보스(14)의 일측에 본드유입홈(15a)을 형성하고, 그 본드유입홈(15a) 중간부에 구비한 본드주입구(15)을 통해 본드(16)를 주입하여 회전축(11)에 고정되도록 구성한 것이다.As shown in FIGS. 2 to 4, the present invention is configured to couple the preload boss 14 integrally to the rotating shaft 11 connected to the drum motor, the preload boss 14 is the upper and lower parts of the lower drum 12 Although the structure configured to apply a constant pressure to the bearings (13) and (13a) is the same as in the prior art, it is unusual in the present invention to form a bond inlet groove (15a) on one side of the preload boss (14), and the bond inlet groove. (15a) The bond 16 is injected through the bond inlet 15 provided in the middle portion to be fixed to the rotary shaft 11.
상기와 같이 구성된 본 발명은 하부베어링(13)에 예압을 가하면서 회전축(11)에 본드(16)로 예압보스(14)가 고정되기 때문에 유동되지 않으며, 하부드럼(12)이 회전시 스크루등에 의한 풀림이 없어져 그 예압보스(14)의 역할인 예압을 항상 일정하게 베어링(13)(13a)에 가할 수 있게 되는 것이다.The present invention configured as described above does not flow because the preload boss 14 is fixed to the rotating shaft 11 by the bond 16 while applying the preload to the lower bearing 13, and the lower drum 12 is rotated to a screw or the like. The loosening caused by this is eliminated so that the preload, which is the role of the preload boss 14, can always be constantly applied to the bearings 13 and 13a.
따라서 이와같은 본 발명에 의하면 본드 삽입구를 갖는 예압보스를 본드로 회전축에 고정시키기 때문에 종래의 스크루를 조여야 하는 문제가 없어 지게 되어 조립공정이 감소하므로써 생산성이 향상되는 효과가 있다.Therefore, according to the present invention, there is no problem of tightening the conventional screw because the preload boss having a bond insertion hole is fixed to the rotary shaft by the bond, thereby reducing productivity of the assembly process.
또한, 본 발명은 종래의 스크루에 의한 고정이나 스프링 와샤를 사용하지 않고 본드를 이용하여 고정시킴으로써 고정부분이 풀리지 않으면서 지속적으로 예압을 가하여 부속이 줄어들게 되고, 조립이 간단해 지는 효과가 있다.In addition, the present invention is fixed by using a bond without using a conventional screw or a spring washer by applying a preload continuously without loosening the fixing portion is reduced in parts, there is an effect that the assembly is simplified.
