Description

진동모터용 진동자{VIBRATOR OF VIBRATION MOTORS}Vibrator for Vibration Motors {VIBRATOR OF VIBRATION MOTORS}

본 발명은 선별기 등에 사용되는 진동모터용 진동자에 관한 것으로서, 보다 상세하게는 제 1 편심자와 제 2 편심자로 구성되어, 진동모터의 샤프트가 어느 한 방향으로 회전되면 제 1 편심자와 제 2 편심자의 겹침 구역이 많아져 진폭이 크고, 샤프트가 반대로 회전되면, 제 1 편심자와 제 2 편심자의 겹침 구역이 상대적으로 적어져 진폭이 작은 진동모터용 진동자에 관한 것이다.The present invention relates to a vibrator for a vibration motor for use in a sorter, and more particularly, comprising a first eccentric and a second eccentric, the first eccentric and the second eccentric when the shaft of the vibration motor is rotated in either direction When the overlap region of the ruler is large, and the amplitude is large, and the shaft is rotated in the opposite direction, the overlap region of the first and second eccentrics is relatively small, and thus the oscillator for the vibration motor having a small amplitude.

도 4를 참조하면, 일반적으로 진동모터(100)는 샤프트(110)에 진동자(120)가 고정되어 있어, 샤프트(110)의 회전속도가 높아지면 진동이 커지고, 샤프트의 회전속도가 낮아지면 진동이 작아진다.Referring to FIG. 4, in general, the vibration motor 100 has a vibrator 120 fixed to the shaft 110, so that the vibration increases when the rotation speed of the shaft 110 increases, and the vibration occurs when the rotation speed of the shaft decreases. Becomes smaller.

그러나, 상기와 같은 종래의 진동모터는 샤프트의 회전속도를 변경하지 않는 상태에서 진폭을 크게 하거나 작게 하여 진동의 세기를 변경할 수 없었다.However, the conventional vibration motor as described above could not change the intensity of vibration by increasing or decreasing the amplitude without changing the rotational speed of the shaft.

따라서, 본 발명의 목적은 제 1 편심자와 제 2 편심자로 구성되어, 진동모터의 샤프트가 어느 한 방향으로 회전되면 제 1 편심자와 제 2 편심자의 겹침 구역이 많아져 진폭이 크고, 샤프트가 반대로 회전되면, 제 1 편심자와 제 2 편심자의 겹침 구역이 상대적으로 적어져 진폭이 작아짐으로써, 동일한 회전속도에서 모터의 회전방향을 변경하여, 진동의 세기를 변경할 수 있는 진동모터용 진동자를 제공하는 것이다.Accordingly, an object of the present invention is composed of a first eccentric and a second eccentric, and when the shaft of the vibration motor is rotated in either direction, the overlapping area of the first eccentric and the second eccentric increases, so that the amplitude is large and the shaft When rotated conversely, the overlapping area of the first and second eccentrics becomes relatively small and the amplitude becomes small, thereby providing a vibrator for a vibration motor that can change the intensity of vibration by changing the rotational direction of the motor at the same rotational speed. It is.

상기 목적을 달성하기 위한 본 발명에 따른 진동모터용 진동자는 모터의 샤프트에 고정되는 제 1 편심자와, 베어링을 통해 샤프트에 장착되는 제 2 편심자로 구성되고, 제 1 편심자에 돌기가 장착되어, 제 1 편심자의 일단과 돌기 사이의 배치간격 보다 제 1 편심자의 타단과 돌기 사이의 배치간격이 상대적으로 큰 것을 특징으로 한다.The vibrator for a vibration motor according to the present invention for achieving the above object is composed of a first eccentric fixed to the shaft of the motor, a second eccentric mounted to the shaft through the bearing, the projection is mounted on the first eccentric In addition, the arrangement interval between the other end and the projection of the first eccentric than the placement interval between one end and the projection of the first eccentric is characterized in that it is relatively large.

상기 샤프트의 회전 방향에 따라 돌기에 의해 제 1 편심자와 제 2 편심자의 겹치는 구역이 변경되는 것을 특징으로 한다.The overlapping area of the first eccentric and the second eccentric is changed by the projection according to the rotation direction of the shaft.

이것에 의해, 본 발명에 따른 진동모터용 진동자는 모터의 회전 방향에 따라 진동의 세기를 변경할 수 있으며, 저속에서 진동의 세기를 낮추지 않고 진동주기를 길게 하거나, 고속에서 작은 진동으로 진동주기를 짧게 할 수 있어, 진동모드를 다양하게 변경할 수 있는 효과가 있다.As a result, the vibrator for the vibration motor according to the present invention can change the intensity of vibration according to the rotational direction of the motor, and lengthen the vibration period without lowering the intensity of the vibration at low speed, or shorten the vibration cycle with the small vibration at high speed. There is an effect that can be changed in a variety of vibration modes.

이하, 본 발명에 따른 바람직한 실시예를 도면을 참조하여 상세하게 설명하기로 한다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

도 1 내지 도 3을 참조하면, 본 발명에 따른 진동 모터용 진동자는 모터(40)의 샤프트(30)에 고정되는 제 1 편심자(10)와, 베어링(22)을 통해 샤프트(30)에 장착되는 제 2 편심자(20)로 구성되고, 제 1 편심자(10)에 돌기(15)가 장착되어, 제 1 편심자(10)의 일단(11)과 돌기(15) 사이의 배치간격(S1) 보다 제 1 편심자(10)의 타단(12)과 돌기(15) 사이의 배치간격(S2)이 상대적으로 크다.1 to 3, a vibrator for a vibrating motor according to the present invention is connected to the shaft 30 through a first eccentric 10 fixed to the shaft 30 of the motor 40 and a bearing 22. It is composed of a second eccentric 20 to be mounted, the projection 15 is mounted on the first eccentric 10, the arrangement interval between the one end 11 and the projection 15 of the first eccentric 10 The arrangement interval S2 between the other end 12 and the projection 15 of the first eccentric 10 is relatively larger than S1.

상기 제 1 편심자(10) 및 제 2 편심자(20)는 부채꼴 형상으로 형성되며, 도 2 및 도 3에 반원 형상으로 도시된 것에 한정되지 않는다.The first eccentric 10 and the second eccentric 20 are formed in a fan shape, and are not limited to those shown in a semicircular shape in FIGS. 2 and 3.

상기와 같이 구성된 본 발명에 따른 진동모터용 진동자는, 도 2에 도시된 바와같이, 모터(40)의 샤프트(30)가 어느 한 방향(예를 들어, 반시계 방향)으로 회전되면, 상기 샤프트(30)에 고정된 제 1 편심자(10)가 샤프트(30)와 같은 방향으로 회전하게 됨으로써, 제 1 편심자(10)의 돌기(15)에 제 2 편심자(20)가 걸려, 제 2 편심자(20)가 제 1 편심자(10)와 같이 회전하게 된다. 이때, 상기 제 1 편심자(10)와 제 2 편심자(20)가 겹치는 구역(A)이 발생하여, 회전하는 샤프트(30)에 편심하 중이 발생하게 됨으로써, 상기 샤프트에 진동이 발생하게 된다.The vibrator for a vibration motor according to the present invention configured as described above, when the shaft 30 of the motor 40 is rotated in one direction (for example, counterclockwise), as shown in Figure 2, the shaft As the first eccentric 10 fixed to the 30 is rotated in the same direction as the shaft 30, the second eccentric 20 is caught by the projection 15 of the first eccentric 10, The two eccentrics 20 rotate together with the first eccentric 10. At this time, a region A in which the first eccentric 10 and the second eccentric 20 overlap each other is generated, and an eccentric load is generated on the rotating shaft 30, thereby causing vibration in the shaft. .

그리고, 도 3에 도시된 바와같이, 모터(40)의 샤프트(30)가 반대 방향(시계 방향)으로 회전되면, 돌기(15)에 의해 제 1 편심자(10)와 제 2 편심자(20)가 겹치는 구역(B)이 모터(40)의 샤프트(30)가 반시계 방향)로 회전되어 제 1 편심자(10)와 제 2 편심자(20)가 겹치는 구역(A) 보다 겹침 면적이 크게 되어, 샤프트(30)에 작용하는 편심하중이 커짐으로써, 샤프트의 진동의 세기가 증가된다.As shown in FIG. 3, when the shaft 30 of the motor 40 is rotated in the opposite direction (clockwise), the first and second eccentrics 10 and 20 are separated by the projections 15. ), The overlapping area B is rotated in the counterclockwise direction of the shaft 30 of the motor 40 so that the overlapping area is greater than the area A where the first eccentric 10 and the second eccentric 20 overlap. The larger the eccentric load acting on the shaft 30, the greater the intensity of vibration of the shaft.

즉, 샤프트(30)의 회전속도가 동일한 상태에서, 샤프트(30)가 시계방향으로 회전되면, 반시계방향으로 회전될 때모다 진동의 세기가 증가된다.That is, when the shaft 30 is rotated clockwise in the state where the rotational speed of the shaft 30 is the same, the intensity of vibration increases when the shaft 30 is rotated counterclockwise.

따라서, 본 발명에 따른 진도모터용 진동자는 샤프트(30)의 회전속도가 동일한 상태에서, 샤프트(30)의 회전 방향을 변경함으로써, 진동의 세기를 변경할 수 있을 뿐만 아니라 저속으로 샤프트(30)를 시계방향으로 회전시켜, 진동의 세기를 낮추지 않고 상대적으로 진동주기를 길게 하거나, 고속으로 샤프트(30)를 반시계 방향으로 회전시켜 작은 진동으로 진동주기를 짧게 할 수 있다.Therefore, the vibration motor for the progress motor according to the present invention, by changing the rotational direction of the shaft 30 in the state that the rotational speed of the shaft 30 is the same, not only can change the strength of the vibration but also the shaft 30 at a low speed By rotating clockwise, the vibration period can be relatively long without lowering the intensity of the vibration, or the shaft 30 can be rotated counterclockwise at a high speed to shorten the vibration period with a small vibration.
