부가적인 소음방지용 볼을 구비한 디스크 턴테이블결합장치Disc turntable coupling device with additional noise protection ball

본 발명은 디스크를 고속으로 회전시켜 기록된 정보를 재생할 때에 디스크의 편중심, 편향특성으로 인해 발생되는 진동을 방지하기 위한 디스크 턴테이블결합장치에 관한 것으로서, 특히 진동을 보상하기 위해 부가적으로 발생하는 소음을 제거할 수 있도록 된 디스크 턴테이블결합장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk turntable coupling apparatus for preventing vibration caused by the disk's eccentricity and deflection characteristics when the disk is rotated at high speed to reproduce recorded information. Disc turntable coupling device that can eliminate the noise.

일반적으로, 디스크 턴테이블결합장치는 디스크를 안착하여 고속 회전시키므로 디스크가 편중심, 편향특성을 나타내면 디스크의 회전시에 진동이 발생하게 된다.In general, since the disk turntable coupling apparatus mounts the disk and rotates at high speed, vibration occurs when the disk is rotated if the disk exhibits eccentricity and deflection characteristics.

도1 및 도2에서 보는 바와같이, 종래의 턴테이블결합장치는 모터(100)의 회전축(140)과 일체로 결합되어 디스크(120)를 회전시키기 위한 원통형상의 디스크지지대(110), 및 디스크의 고속 회전시 양력의 작용에 의해 상승하려는 디스크를 고정하기 위한 고정편(130)을 구비하고 있다. 특히, 디스크지지대(110)의 내측부에는 내벽으로부터 일정 거리 이격된 격벽(110a)이 원주방향으로 형성되어 있으며, 이러한 내벽과 격벽간의 공간에는 진동보상용 강철볼(150)이 원주방향으로 원형 격벽을 따라 구름동작할 수 있도록 다수개 배치되어 있다.As shown in Figures 1 and 2, the conventional turntable coupling device is integrally coupled with the rotating shaft 140 of the motor 100, the cylindrical disk support 110 for rotating the disk 120, and the high speed of the disk It is provided with a fixing piece 130 for fixing the disk to be raised by the action of lifting force during rotation. Particularly, the inner side of the disk support 110 is formed with a partition wall 110a spaced apart from the inner wall in a circumferential direction. In the space between the inner wall and the partition wall, a vibration compensating steel ball 150 forms a circular partition wall in the circumferential direction. It is arranged in a number of ways so that the cloud can operate.

따라서, 모터(100)를 작동시켜 디스크지지대(110)가 디스크(120)를 지지한 상태로 회전시킬 경우에, 도3에서 보는 바와같이 디스크의 편중심, 편향특성으로 인해 진동이 발생하게 되면 디스크의 편중심(O)와 대향하는 쪽으로 진동보상용 강철볼(150)들이 구름동작하여 몰리게 됨으로써 디스크의 회전진동이 제거될 수 있는 것이다.Therefore, when the disk support 110 is rotated while supporting the disk 120 by operating the motor 100, as shown in Figure 3, when the vibration occurs due to the eccentricity, deflection characteristics of the disk disk Vibration-compensated steel balls 150 to the side opposite to the center of gravity (O) of the rolling motion will be driven to be eliminated the rotational vibration of the disk.

한편, 턴테이블결합장치는 도1내지 도3에서 보는 바와같이 디스크가 수평상태로 장착되게 할 수도 있지만, 이와는 달리 도4 및 도5에서와 같이 디스크가 수직상태로 장착되게 할 수도 있다. 도4 및 도5에서 보는 바와같이 턴테이블이 가로방향으로 설치된 경우에는, 모터(100)를 작동시켜 디스크지지대(110)가 디스크(120)를 지지한 상태로 회전시키게 되면 진동보상용 강철볼(150)들이 디스크지지대의 하측부에 몰려 구름동작하게 됨으로써, 디스크의 편중심, 편향특성으로 인한 진동을 어느정도 보상할 수 있는 것이다.On the other hand, the turntable coupling device may allow the disk to be mounted in a horizontal state as shown in FIGS. 1 to 3, but alternatively, the disk may be mounted in a vertical state as shown in FIGS. 4 and 5. 4 and 5, when the turntable is installed in the horizontal direction, when the disk support 110 is rotated while supporting the disk 120 by operating the motor 100, the vibration compensation steel ball 150 ) Are crowded by the lower part of the disk support, so that the vibration due to the disk's eccentricity and deflection characteristics can be compensated to some extent.

하지만, 이러한 종래의 턴테이블결합장치는 디스크의 편중심, 편향특성으로 인한 진동을 제거하기 위해 장착된 진동보상용 강철볼들이 단단한 금속재질로써 제작되어 설치됨으로써, 모터의 고속회전시에 강철볼들이 상호 충돌하여 부가적인 소음이 발생하게 되는 문제점이 있었다. 이에, 본 발명은 이러한 문제점을 해결하기 위해 안출된 것으로서, 그 목적은 수평 또는 수직방향에서 디스크를 고속재생할 경우 강철볼들의 상호 충돌에 의해 발생하는 소음을 방지할 수 있는 턴테이블결합장치를 제공함에 있다.However, such a conventional turntable coupling device is made of a rigid metal material of vibration compensation steel balls mounted to remove vibrations due to the eccentricity and deflection characteristics of the disk, so that the steel balls are mutually rotated at high speed of the motor. There was a problem that additional noise is generated by collision. Accordingly, the present invention has been made to solve this problem, the object of the present invention is to provide a turntable coupling device that can prevent the noise caused by the collision of steel balls when the disk is played at high speed in the horizontal or vertical direction. .

위와같은 목적을 달성하기 위한 본 발명의 특징은 디스크를 고속으로 회전시켜 기록된 정보를 재생할 때에 디스크의 편중심, 편향특성으로 인해 발생되는 진동을 방지할 수 있도록 된 디스크 턴테이블결합장치에 있어서, 모터의 회전축과 일체로 회동가능하게 연결되어 회전축으로부터 인가되는 회전력에 의해 디스크를 회전시키고, 내부의 중공부분에는 원주방향으로 형성된 수용공간이 형성되어 어느 정도 하중을 갖는 구형상의 볼들이 수용공간을 통해 회전가능하도록 배치된 디스크 지지대를 구비하고; 다수 개의 볼들 간에는 마찰방지를 위해 유연한 재질의 마찰방지용 볼들이 배치된 디스크 턴테이블결합장치에 있다.A feature of the present invention for achieving the above object is a disk turntable coupling apparatus which can prevent the vibration caused by the disk's eccentricity, deflection characteristics when playing the recorded information by rotating the disk at high speed, the motor The disk is rotated by a rotational force applied integrally with the rotating shaft of the rotating shaft, and an inner hollow portion is formed with a receiving space formed in the circumferential direction so that spherical balls having a certain load rotate through the receiving space. Having a disk support arranged to be capable of; In the disk turntable coupling device in which the friction prevention balls of a flexible material are arranged to prevent friction between the plurality of balls.

이하에서 본 발명의 구성 및 작용을 설명하기 위해 첨부된 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings to explain the configuration and operation of the present invention.

도6에 도시된 바와같이, 본 발명에 따른 디스크 턴테이블결합장치는 진동보상용 강철볼(15)간에 플라스틱과 같은 유연한 재질로써 제작된 마찰방지용 볼(16)들을 배치하여 회전시에 강철볼들간의 마찰에 의한 소음발생을 방지하고 있다.As shown in Fig. 6, the disc turntable coupling device according to the present invention arranges the friction preventing balls 16 made of a flexible material such as plastic between the steel balls 15 for vibration compensation, and then rotates the steel balls between the steel balls during rotation. Noise is prevented by friction.

턴테이블결합장치는 강철볼(15)간에 배치된 마찰방지용 볼(16)을 제외하고는 종래의 장치와 동일한 구조로 제작된다. 디스크지지대(11)는 모터(10)의 회전축(14)과 연결되어 있다. 여기서, 디스크를 회전시키기 위한 회전력을 인가하는 모터(10)로는 주로 스핀들모터가 사용된다. 이와같이, 디스크지지대(11)는 모터(10)로부터 회전력을 인가받아 디스크(12)를 회전시키는 역할을 하는 것으로서 중공의 원통형상으로 제작되며, 그 내부에는 원통벽과 일정 거리 이격된 격벽(11a)이 형성되어 있다. 게다가, 이러한 원통벽과 격벽간의 이격공간에는 다수 개의 진동보상용 강철볼(15)이 구름가능하게 배치되어 있고, 이러한 강철볼(15)들 사이에는 마찰방지용 볼(16)들이 배치되어 있다. 덧붙여, 디스크지지대(11)의 상측에는 디스크(12)의 안착시에 디스크를 고정하여 디스크지지대(11)로부터 이탈되지 않도록 하기 위한 고정편(미도시)이 구성되어 있다.The turntable coupling device is manufactured in the same structure as the conventional device except for the friction preventing ball 16 disposed between the steel balls 15. The disk support 11 is connected to the rotating shaft 14 of the motor 10. Here, the spindle motor is mainly used as the motor 10 applying the rotational force for rotating the disk. As described above, the disk support 11 serves to rotate the disk 12 by applying rotational force from the motor 10 and is manufactured in a hollow cylindrical shape, and the partition wall 11a spaced apart from the cylindrical wall by a predetermined distance therein. Is formed. In addition, a plurality of vibration compensation steel balls 15 are cloudably arranged in the space between the cylindrical wall and the partition wall, and the friction preventing balls 16 are disposed between the steel balls 15. In addition, a fixing piece (not shown) is provided on the upper side of the disk support 11 to fix the disk so as not to be detached from the disk support 11 when the disk 12 is seated.

따라서, 턴테이블결합장치가 수평 혹은 수직상태로 설치된 후, 모터(10)를 작동시켜 디스크지지대(11)가 디스크(12)를 회전시키게 하면 디스크의 편중심, 편향특성으로 인해 진동이 발생할 경우에 진동보상용 강철볼(15)이 디스크의 편중심(O)과 대향하는 쪽으로 구름동작하여 몰리게 된다. 이때에, 진동보상용 강철볼(15)들 간에 배치된 마찰방지용 볼(16)은 디스크의 회전에 의한 강철볼(15)들간의 마찰을 방지하게 됨으로써, 편중심 및 편향특성에 의한 디스크의 진동을 소음발생없이 제거할 수 있는 것이다.Therefore, after the turntable coupling device is installed in a horizontal or vertical state, when the disk support 11 rotates the disk 12 by operating the motor 10, the vibration occurs when vibration occurs due to the eccentricity and deflection characteristics of the disk. The compensating steel ball 15 is driven by rolling toward the disk center of gravity (O). At this time, the anti-friction ball 16 disposed between the vibration compensation steel balls 15 to prevent the friction between the steel balls 15 by the rotation of the disk, the vibration of the disk due to the eccentricity and deflection characteristics Can be removed without noise.

상술한 바와같이, 본 발명에 따른 디스크 턴테이블결합장치는 디스크의 편중심 및 편향특성으로 인해 발생되는 디스크의 진동을 보상하기 위해 다수 개의 강철볼이 회전가능하게 배치되고, 그 강철볼들 간에 마찰을 방지하기 위한 유연한 재질의 마찰방지용 볼들이 배치됨으로써, 강철볼들의 회전시 상호 마찰에 의한 소음의 발생없이 디스크의 진동을 방지할 수 있는 효과가 있다.As described above, in the disk turntable coupling apparatus according to the present invention, a plurality of steel balls are rotatably arranged to compensate for the vibration of the disk caused by the eccentricity and deflection characteristics of the disk, and the friction between the steel balls is reduced. By preventing the friction ball of the flexible material is disposed to prevent, there is an effect that can prevent the vibration of the disk without generating noise due to mutual friction during the rotation of the steel balls.
