본 발명은 고속텝핑머신 등에 사용되는 급제동 정.역회전 모터에 관한 것으로, 더욱 자세하게는 정.역회전하는 고속모터의 브레이크와 모터 내부를 냉각시켜주기 위한 급제동모터의 냉각구조에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rapid braking forward and reverse rotation motor used in a high speed tapping machine, and more particularly, to a brake of a high speed motor that is forward and reverse rotation and a cooling structure of a rapid braking motor for cooling the inside of the motor.

종래의 고속텝핑머신 등에 사용되어온 급제동 정.역회전 모터를 보면, 도 1에 도시된 바와 같이 모터하우징(1)과 모터축(2)과 이 모터축(2)의 후단부에 설치되어 모터축(2)을 급제동시켜주는 브레이크(3)가 구비되어 있다.As shown in FIG. 1, a rapid braking forward and reverse rotation motor used in a conventional high speed tapping machine is installed at a rear end of the motor housing 1, the motor shaft 2, and the motor shaft 2. The brake 3 which brakes (2) is provided.

상기와 같은 급제동 정.역회전모터는 외부의 조작에 의하여 회전방향을 바꿀 때 급제동 브레이크(3)가 모터축(2)을 잡아주어야 하며 이때 모터축(2)과 브레이크(3) 사이에서 마찰이 일어나므로 필연적으로 열이 발생하게 된다. The rapid braking forward / reverse rotation motor as described above should be applied by the external brake to the motor brake (2) to hold the motor shaft (2) when the direction of rotation changes, the friction between the motor shaft (2) and the brake (3) As a result, heat is inevitably generated.

이렇게 발생되는 열은 모터축(2)이 고속회전하면서 그 회전방향이 정.역으로 자주 바뀔 때 과열현상이 발생하고 이러한 과열은 급제동 브레이크(3)의 수명에 지대한 악영향을 끼치게 되므로 적극적인 냉각이 필요하게 된다. Heat generated in this way is overheated when the motor shaft (2) rotates at high speed and its rotation direction is frequently reversed and reversed, and this overheating has a great negative effect on the life of the brake system (3). Done.

그럼에도 불구하고 종래에는 브레이크커버(4)에 통기공(4a)을 형성하여 자연대류에 의한 냉각에만 의존하여 왔다. Nevertheless, the ventilation holes 4a are formed in the brake cover 4 in the related art and have only been dependent on cooling by natural convection.

그러나, 이러한 냉각방법은 브레이크와 모터축의 마찰부위에서의 과열을 방지하기엔 미흡하여 제품의 효율저하와 수명단축 등의 문제점은 그대로 감수해야하는 실정이었다.However, such a cooling method is insufficient to prevent overheating at the friction part of the brake and the motor shaft, so that problems such as deterioration of efficiency and shortening of life of the product should be taken as it is.

그렇다고, 정회전만 하는 일반모터처럼 모터축에 직접 냉각휀을 설치하려고하여도 고속정.역회전모터에서는 고속정.역회전이 순간적으로 이루어져야 하기 때문에 모터축에 고정되어 있는 냉각휀이 모터축의 순간동작에 무리한 부하를 주게 되므로 이러한 방법은 바람직한 해결책이 될 수 없다.However, even if the cooling fan is installed directly on the motor shaft like a normal motor that only performs forward rotation, the high speed forward and reverse rotation must be instantaneously performed in the high speed forward and reverse rotation motors. This method is not a desirable solution because of the excessive load.

본 발명의 목적은 상기와 같은 종래의 문제점을 해결하기 위하여 모터의 발열부를 적극적으로 냉각시켜 줄 수 있는 냉각휀을 별도의 모터로 구동할 수 있게 한 급제동 모터의 냉각구조를 제공함에 있다. It is an object of the present invention to provide a cooling structure of a rapid braking motor that can be driven by a separate motor to the cooling fan that can actively cool the heating portion of the motor in order to solve the conventional problems as described above.

상기와 같은 목적을 달성하기 위한 본 발명은 모터하우징과 회전자와 고정자와 모터축과 하우징후단의 격판과 브레이크와 브레이크커버가 구비되어 있는 급제동 모터에 있어서, 상기 브레이크의 후방에 별도의 모터에 의해 구동되는 냉각휀을 설치하여 된 특징이 있다.The present invention for achieving the above object is a rapid braking motor provided with a motor housing, a rotor, a stator, a motor shaft and a rear plate of the housing, a brake and a brake cover, by a separate motor at the rear of the brake It is characterized by installing a cooling fan driven.

본 발명은 상기 격판에 공기유입공을 설치하여서 된 다른 특징이 있다.The present invention has another feature made by installing an air inlet hole in the diaphragm.

본 발명은 상기 모터하우징의 전방 적의의 개소에 공기배출공을 천공하여서 된 또 다른 특징이 있다.The present invention has yet another feature made by drilling an air discharge hole at a front enemy location of the motor housing.

이하, 본 발명을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 바람직한 실시예의 일부 절제 측면도이다.2 is a partial cutaway side view of a preferred embodiment of the present invention.

도면에 의하면, 모터하우징(10)의 내부에 고정자(11)와 회전자(12)가 있고 이 회전자(12)의 중앙에 모터축(13)이 설치되어 있다. 상기 하우징(10)의 후단에 격판(14)이 설치되고 이의 후방에 공기유입공(21)이 천공된 브레이크커버(20)가 설치되며 이 브레이크커버(20)의 내부로 모터축(13)이 연장 돌출되게 하여 이 연장부에 급제동 브레이크(30)가 구비되어 있다.According to the figure, the stator 11 and the rotor 12 are provided inside the motor housing 10, and the motor shaft 13 is provided in the center of this rotor 12. As shown in FIG. In the rear end of the housing 10, a diaphragm 14 is installed, and a rear side of the brake cover 20 in which the air inlet hole 21 is drilled is installed, and the motor shaft 13 is inserted into the brake cover 20. A protruding braking brake 30 is provided in the extension portion so as to extend and protrude.

상기 브레이크(30)의 후방에는 이 브레이크(30)에 바람을 불어주는 냉각 휀(40)이 설치되는데, 이 냉각휀(40)은 모터(41)에 의해 구동되는 것으로 상기 브레이크커버(20)의 후단부의 내측면에 부착된다. At the rear of the brake 30, a cooling fan 40 for blowing air to the brake 30 is installed. The cooling fan 40 is driven by a motor 41. It is attached to the inner side of the rear end.

또, 상기의 격판(14)에는 다수의 통기공(14a)이 천공되어 있으며, 필요에 따라 안전보호망(15)을 설치할 수도 있다(도 3 참조).In addition, a plurality of vent holes 14a are drilled in the diaphragm 14, and a safety net 15 may be provided as necessary (see FIG. 3).

또, 상기 모터하우징(10)의 전방 적의의 개소에 공기배출공(10a)이 형성될 수 있다.In addition, the air discharge hole (10a) may be formed in the location of the front enemy of the motor housing (10).

미설명부호 50은 컨트롤부이다.Reference numeral 50 is a control unit.

상기와 같이 구성된 본 발명은 컨트롤부(50)를 조작하여 냉각휀(40)을 구동시키면 브레이크커버(20)의 공기유입공(21)을 통해 외부공기가 유입되어 브레이크(30)를 냉각시키게 되고 다음 격판(14)의 통기공(14a)을 통하여 모터 내부로 들어가 회전자(12)와 고정자(11) 사이로 흘러들어가 모터 내부를 냉각시키게 된다. In the present invention configured as described above, when the cooling fan 40 is driven by operating the control unit 50, external air is introduced through the air inlet hole 21 of the brake cover 20 to cool the brake 30. Next, it enters into the motor through the vent hole 14a of the diaphragm 14 and flows between the rotor 12 and the stator 11 to cool the inside of the motor.

이러한 본 발명은 냉각휀(41)을 모터축(13)에 직접 설치하지 않고 별도의 구동수단에 의해 구동되게 함으로서 냉각휀(41)이 모터축(13)의 순간동작에 방해될 려가 없다.The present invention does not interfere with the instantaneous operation of the motor shaft 13 by allowing the cooling fan 41 to be driven by a separate driving means without directly installing the cooling fan 41 on the motor shaft 13.

본 발명의 실시예를 시험하여본 결과에 따르면 모터하우징(10)의 전방에 공기배출공(10a)이 없어도 만족할만한 냉각효과를 얻었으므로 공기배출공(10a)이 본 발명의 필수요건에서는 제외되나 냉각휀(41)의 성능이나 기타 다른 요인에 따라서는 공기배출공(10a)을 천공할 수도 있다. According to the results of the test of the embodiment of the present invention, a satisfactory cooling effect was obtained even without the air exhaust hole 10a in front of the motor housing 10, but the air discharge hole 10a is excluded from the essential requirements of the present invention. Depending on the performance of the cooling fan 41 and other factors, the air discharge hole 10a may be drilled.

이상 설명된 바와 같은 본 발명은 과열되기 쉬운 브레이크를 적극적으로 냉각시켜주게 되므로 브레이크의 수명을 크게 연장시켜 줄 수 있으며, 동시에 모터 내부도 냉각시켜 줌으로서 제품의 효율을 크게 향상시켜주는 이점이 있다.As described above, the present invention actively cools a brake that is easily overheated, thereby greatly extending the life of the brake, and simultaneously cooling the inside of the motor, thereby greatly improving the efficiency of the product.
