Description

스프링을 이용한 브레이크 장치가 결합된 모터 {SPRING BRAKE MOTOR}Motor with brake device using spring {SPRING BRAKE MOTOR}

본 고안은 전동셔터나 혹은 크레인류에 속하는 모터에 관한 것으로 특히, 피동측의 하중이나 다른 외부 힘에 의한 모터의 회전을 구속하는 것에 관한 것이다.The present invention relates to a motor belonging to an electric shutter or a crane, and more particularly, to restrain the rotation of the motor by a load on the driven side or other external force.

일반적으로 전동셔터의 경우는 모터의 후면에 디스크 드럼을 이용한 브레이크 장치를 부착하여 자중강하를 방지하고 보조 디스크 제동장치로 하강시의 가속을 조절하는 구조로 되어있으나, 그로 인하여 모터에 과부하가 발생되어 연속 작동시 과열의 위험이 내재되어 있다.In general, in the case of the electric shutter, a brake device using a disc drum is attached to the rear of the motor to prevent a drop in self-weight and to control the acceleration at the time of descending with an auxiliary disc brake device. The risk of overheating is inherent in continuous operation.

본 고안은 전동셔터의 셔터자중에 의한 하강시의 가속을 차단하고 지정된 위치에서의 정지상태를 안전하게 유지시켜 주는 데에 목적이 있다.The object of the present invention is to block acceleration during the fall by the shutter's own weight of the electric shutter and to keep the stop state safely at a designated position.

이를 달성하기 위한 본 고안은, 스프링(9)을 고정하고 스프링(9)의 마찰력을 얻기 위해 브라켓(7)에 스프링(9)을 끼우고 그 위에 모터(1)의 동력을 스프링(9)에 전달하는 플레이트(11)를 감속기어부(6)의 최종샤프트와 결합하여 스프링(9)의 외경면에 안치한다. 스프링의 후크(16,17)가 플레이트(11)와 샤프트부(13)의 사이에 위치하게 조립되는 것을 특징으로 하며, 샤프트부(13)의 회전력이 작용하면 스프링의 후크(16,17)가 안쪽으로 힘을 받아 스프링(9) 내경이 줄어들면서 브라켓(7) 외면을 조여져 마찰력이 발생되고, 플레이트(11)에 동력이 전달되면 스프링의 후크(16,17)가 바깥쪽으로 힘을 받아 스프링(9)이 늘어나게 되어 마찰력이 줄어들게 구성되어 있다.In order to achieve this, the present invention fits the spring (9) to the bracket (7) to fix the spring (9) and to obtain the friction force of the spring (9), and the power of the motor (1) thereon to the spring (9) The plate 11 to be transmitted is combined with the final shaft of the reduction gear unit 6 and placed on the outer diameter surface of the spring 9. The hooks 16 and 17 of the spring are assembled to be located between the plate 11 and the shaft portion 13, and when the rotational force of the shaft portion 13 is applied, the hooks 16 and 17 of the spring are As the inner diameter of the spring (9) decreases due to the force inward, friction is generated by tightening the outer surface of the bracket (7), and when the power is transmitted to the plate (11), the hooks (16, 17) of the spring are forced outward and the spring ( 9) is increased to reduce friction.

이하, 본 고안의 구성 및 동작을 첨부 도면에 의거 더욱 상세히 설명한다.Hereinafter, the configuration and operation of the present invention will be described in more detail with reference to the accompanying drawings.

도 4 는 스프링(9)과 플레이트(11),샤프트부(13)의 구성을 이해하기 위한 개략도 이다.4 is a schematic view for understanding the configuration of the spring 9, the plate 11, the shaft portion (13).

도 5 는 스프링(9)과 플레이트(11),샤프트부(13)의 상호작용을 설명하기 위한 설명도이다.5 is an explanatory diagram for explaining the interaction between the spring 9, the plate 11, and the shaft portion 13.

도 1 에서, 모터부(1)를 커버(4)에 체결하고 감속기어부(6)를 커버(4)에 고정한다.In FIG. 1, the motor part 1 is fastened to the cover 4 and the reduction gear part 6 is fixed to the cover 4.

브라켓(7)에 와샤 A(8)를 삽입하고 그 위에 스프링(9)을 끼운 후 와샤B(10)를 올려놓고 플레이트(11)를 씌운다. 그 위에 와샤 C(12)를 올리고 샤프트부(13)로 덮는다. 이것을 베어링(14)이 삽입된 케이스(15)에 체결하고 감속기어부(6)의 최종샤프트 끝단 홈이 플레이트(11) 홈과 고정되게 구성하였다.Insert washer A (8) into bracket (7), insert spring (9) on it, put washer B (10) on, and cover plate (11). The washer C 12 is placed on it, and covered with the shaft portion 13. This was fastened to the case 15 into which the bearing 14 was inserted, and the final shaft end groove of the reduction gear 6 was fixed to the plate 11 groove.

감속기어부(6) 최종 출력측 샤프트를 리미트 스위치(2)에 부착하여 출력회전수를 원하는 양만큼 조절할 수 있게 구성된다.The reduction gear unit 6 is configured to attach the final output side shaft to the limit switch 2 so as to adjust the output rotation speed by a desired amount.

상기한 구성에 의한 동작 관계를 이하, 상세히 설명한다.The operation relationship by the above-mentioned structure is demonstrated in detail below.

모터부(1)의 동력은 감속기어부(4)를 통하여 플레이트(11)로 전달되고, 플레이트(11)는 스프링(9)과 샤프트부(13)로 동력을 전달하여 회전시킨다.Power of the motor unit 1 is transmitted to the plate 11 through the reduction gear unit 4, the plate 11 transmits the power to the spring 9 and the shaft portion 13 to rotate.

역으로 모터부(1)의 동력이 아닌 외부 관성에 의한 회전력이 샤프트부(13)에 작용하면 그 힘은 스프링(9)의 후크(16,17)로 전달되어 스프링(9)이 조여지게 되며 그로 인한 마찰력과 장력이 작용하여 샤프트부(13)의 회전력은 여기서 차단된다.On the contrary, when the rotational force by the external inertia rather than the power of the motor unit 1 acts on the shaft unit 13, the force is transmitted to the hooks 16 and 17 of the spring 9 to tighten the spring 9. The resulting frictional forces and tensions act to block the rotational force of the shaft portion 13 here.

모터부(1)의 동력이 작용할 때 동방향으로 샤프트부(13)에 회전력이 모터의 출력보다 크게 작용할 경우에도 샤프트부(13)의 회전력은 스프링(9)과 브라켓(7)에 의해 차단됨으로 안정적인 회전력을 얻을 수 있다.Even when the rotational force acts on the shaft portion 13 in the same direction when the power of the motor portion 1 is greater than the output of the motor, the rotational force of the shaft portion 13 is blocked by the spring 9 and the bracket 7. A stable rotational force can be obtained.

상기한 본 고안은 모터와 브레이크 시스템이 일체형으로 내장되어 있는 것에 한정하여 설명하였으나 형상은 어떤 형태로든 변형이 가능한 것이므로 굳이 본 고안의 설명이 적용된 모터에 한 한 것은 결코 아니다.The present invention described above is limited to the one in which the motor and the brake system are integrally described, but the shape is not limited to the motor to which the description of the present invention is applied since it can be modified in any form.

이상과 같이 본 고안에 의하면, 전동셔터에 사용되는 부피가 큰 모터를 삼분의 일 수준으로 부피와 무게를 줄일 수 있으며 제조단가 또한 기존 전동셔터 모터에 비하여 저렴한 가격으로 시중에 공급할 수 있는 장점이 있다.As described above, according to the present invention, the bulky motor used for the electric shutter can be reduced to one third of the volume and weight, and the manufacturing unit price can be supplied to the market at a lower price than the conventional electric shutter motor. .
