Description

동력전달장치의 전동모터 과부하 방지장치{Preventing Device of Overloading a Transmission Motor of Power Transmission System} Preventing Device of Overloading a Transmission Motor of Power Transmission System

본 고안은 동력전달장치의 전동모터 과부하 방지장치에 관한 것으로서, 보다 상세하게는 전원공급에 의해 구동되는 전동모터의 회전력을 이용하여 동력을 발생함에 있어, 동력장치의 오작동 및 오류로 인해 발생되는 과부하가 전동모터에 가해지는 것을 방지할 수 있도록 한 동력전달장치의 전동모터 과부하 방지장치에 관한 것이다.The present invention relates to an electric motor overload prevention device of a power transmission device, and more particularly, in generating power by using a rotational force of an electric motor driven by a power supply, an overload caused by a malfunction and an error of a power device. The present invention relates to an electric motor overload preventing device of a power transmission device which can prevent the electric motor from being applied to the electric motor.

일반적으로, 각종 산업기계 및 자동차 등에는 동력전달을 위한 장치로 전동모터가 사용되고 있으며, 전동모터는 소정의 전원[A/C, D/C]을 공급받아 전기에너지를 회전에너지로 변환시키기 위한 것으로서, 현재, 사용하고자 하는 분야 및 출력 사양에 따라, 다양한 형태의 전동모터가 널리 알려져 사용되고 있다.In general, electric motors are used in various industrial machines and automobiles as power transmission devices, and electric motors are provided to convert electric energy into rotational energy by receiving a predetermined power [A / C, D / C]. Currently, various types of electric motors are widely known and used according to fields and output specifications to be used.

전동모터는 전기에너지를 이용하여, 각종 운동에너지로 변환시키기 위해 사용되는 바, 이를 사용하고자 하는 기계에 따라, 동력전달 수단으로 'V'벨트나 체인을 이용하거나, 기어(gear)를 이용하게 된다.Electric motor is used to convert various kinetic energy by using electric energy. Depending on the machine to use it, 'V' belt or chain is used as a power transmission means, or gear is used. .

한편, 종래의 전동모터를 이용한 동력전달장치는 첨부 도면 도 1에 도시된 바와 같이, 전원공급에 의해 전동모터(M)의 회전축(102)이 회전하게 되고, 회전축(102)에는 전동풀리(110)가 결합되고, 전동풀리(110)에는 회전력이 요구되는 피동력체의 종동풀리(112)가 벨트(114)에 의해 연결되도록 이루어진다.On the other hand, in the conventional power transmission device using an electric motor, as shown in Figure 1, the rotary shaft 102 of the electric motor (M) is rotated by the power supply, the electric shaft pulley 110 to the rotary shaft (102) ) Is coupled, the driven pulley 110 is made to be driven by the belt 114 driven pulley 112 of the driven body is required for rotational force.

따라서, 전동모터(M)에 의해 회전축(102)이 회전하게 되면, 전동풀리(110)가 회전되면서, 이에 벨트(114)로 연결된 종동풀리(112)가 회전하여 피동력체에 운동에너지가 전달되어 작동되는 것이다.Therefore, when the rotating shaft 102 is rotated by the electric motor (M), while the electric pulley 110 is rotated, the driven pulley 112 connected to the belt 114 is rotated to transfer the kinetic energy to the driven body. It works.

그러나, 상기와 같은 종래의 동력전달장치에서는 전원공급에 의해 회전되는 전동모터의 회전축에 전동풀리가 결합되고, 전동풀리와 종동풀리가 벨트로 연결되어 있으므로, 피동력체가 작동되는 과정에서, 오동작 및 오류로 인해 과부하가 발생하게 되면, 피동력체에 가해지는 과부하가 전동풀리를 통해 회전축에 전달되어 전동모터에 직접 과부하가 전달되고 있는 실정이다.However, in the conventional power transmission device as described above, since the electric pulley is coupled to the rotary shaft of the electric motor rotated by the power supply, and the electric pulley and the driven pulley are connected by a belt, in the process of operating the driven body, malfunction and When an overload occurs due to an error, the overload applied to the driven body is transmitted to the rotating shaft through the electric pulley and the overload is directly transmitted to the electric motor.

따라서, 피동력체로부터 발생된 과부하가 여과 없이 바로 전동모터에 전달되므로, 과부하로 인해 전동모터의 정상적인 회전이 이루어지지 못하고, 과열되거나 과열로 인해 전동모터가 훼손되는 등의 고장 원인을 제공하게 되었으며, 급기야는 과열로 인해 전동모터의 사용수명이 단축됨은 물론, 전원코일이 연소되어 화재가 발생하게 되는 등의 많은 문제점이 발생하였다.Therefore, since the overload generated from the driven body is directly transmitted to the electric motor without filtration, it is possible to provide a cause of failure such that the electric motor is not rotated normally due to the overload and the electric motor is damaged due to overheating or overheating. In addition, the air supply field shortens the service life of the electric motor due to overheating, and also causes many problems such as the power coil is burned and a fire occurs.

본 고안은 상기와 같은 종래의 문제점을 해결하기 위한 것으로서, 그 목적은 전원공급에 의해 회전력을 발생시키는 전동모터를 이용하여 동력을 전달함에 있어, 전동모터의 회전축과 전동풀리가 직접 고정되지 않고, 이중 구조의 결합방식에 의해 결합되도록 하며, 특히, 피동력체에 과부하가 발생되더라도, 전동모터에는 과부하가 전달되지 않고, 회전축이 항시 동일한 상태로 안정되게 회전이 이루어지도록 된 새로운 형태의 동력전달장치의 전동모터 과부하 방지장치를 제공하고자 하는 것이다.The present invention is to solve the conventional problems as described above, the purpose is to transmit power by using an electric motor that generates a rotational force by the power supply, the rotating shaft and the electric pulley of the electric motor is not directly fixed, A new type of power transmission device, which is to be coupled by a double structure, in particular, even when an overload is generated in the driven body, the overload is not transmitted to the electric motor, and the rotation shaft is always stably rotated in the same state. It is to provide an electric motor overload protection device.

본 고안의 다른 목적은 전동모터를 이용하여 동력을 발생시킴에 있어, 과부하로 인해 전동모터가 훼손되어 사용수명이 단축되는 것을 방지함으로서, 사용수명을 장구히 할 수 있도록 한 것이다.Another object of the present invention is to generate power by using an electric motor, to prevent the electric motor is damaged due to overload to shorten the service life, it is possible to long life.

이와 같은 목적을 달성하기 위하여, 본 고안은 전동모터의 회전축에 전동풀리가 결합됨에 있어서, 상기 전동모터의 회전축과 전동풀리가 베어링이 내설된 과부하 방지장치에 의한 이중 구조로 결합된 특징을 갖는다.In order to achieve the above object, the present invention is characterized in that the electric pulley is coupled to the rotary shaft of the electric motor, the rotary shaft and the electric pulley of the electric motor are combined in a dual structure by the overload protection device built-in bearing.

또한, 제 1회전체는 일측 부위에 체결공이 형성된 축하우징과, 축하우징 끝단부에 용접되어 결합되는 제 1고정판으로 이루어지며, 제 2회전체는 내부에 베어링이 내설된 베어링하우징과, 베어링하우징 외주 면에 용접되어 결합되는 제 2고정판으로 이루어진 특징을 갖는다.

이하, 본 고안을 첨부된 도면에 의해 보다 상세하게 설명하면 다음과 같다.Hereinafter, the present invention in more detail by the accompanying drawings as follows.

도 2 및 도 3에 도시된 바와 같이, 본 고안은 전동모터(M)의 회전축(2)과 전동풀리(4)가 과부하 방지장치(10)에 의한 이중 구조로 결합되는 것으로서, 과부하 방지장치(10)는 제 1, 2회전체(20, 30)가 각각 안전핀(21)과 고정핀(31)에 의해 전동풀리(4)에 결합되는 것이다.As shown in Figure 2 and 3, the subject innovation is that the rotating shaft 2 and the electric pulley 4 of the electric motor (M) is combined in a dual structure by the overload protection device 10, the overload protection device ( 10, the first and second rotating bodies 20 and 30 are coupled to the electric pulley 4 by the safety pin 21 and the fixing pin 31, respectively.

또한, 상기 제 1회전체(20)는 일측 부위에 체결공(22)이 형성된 축하우징(23)과, 축하우징(23) 끝단부에 용접되어 결합되는 제 1고정판(24)으로 이루어지며, 제 2회전체(30)는 내부에 베어링(32)이 내설된 베어링하우징(33)과, 베어링하우징(33) 외주면에 용접되어 결합되는 제 2고정판(34)으로 이루어진다.In addition, the first rotating body 20 is formed of a celebrity housing 23 having a fastening hole 22 formed at one side thereof, and a first fixing plate 24 welded to and coupled to the end of the celebratory housing 23, The second rotating body 30 includes a bearing housing 33 having a bearing 32 therein and a second fixing plate 34 welded to the outer circumferential surface of the bearing housing 33.

이때, 상기 제 1회전체(20)의 제 1고정판(24)은 안전핀(21)에 의해 전동풀리(4)와 결합되고, 제 2회전체(30)의 제 2고정판(34)은 고정핀(31)에 의해 전동풀리(4)와 결합되는 것이다.At this time, the first fixing plate 24 of the first rotating body 20 is coupled to the electric pulley 4 by the safety pin 21, the second fixing plate 34 of the second rotating body 30 is a fixed pin. It is coupled to the electric pulley (4) by (31).

도 2는 본 고안에 따른 동력전달장치의 전동모터 과부하 방지장치를 나타내는 분해 사시도이고, 도 3은 본 고안에 따른 동력전달장치의 전동모터 과부하 방지장치를 나타내는 종단면도로서, 전동모터(M)의 회전축(2)에는 과부하방지장치(10)의 제 1회전체(20)에 축하우징(23)이 끼워져 결합되어 체결볼트(25)에 의해 고정되고, 제 1회전체(20)의 축하우징(23)에는 제 2회전체(30)가 결합되되, 베어링 하우징(33)에 내설된 베어링(32)에 의해 결합되는 것이다.Figure 2 is an exploded perspective view showing an electric motor overload protection device of the power transmission device according to the present invention, Figure 3 is a longitudinal cross-sectional view showing an electric motor overload protection device of the power transmission device according to the present invention, the electric motor (M) The rotating shaft 2 is fitted with the axial housing 23 is fitted to the first rotating body 20 of the overload protection device 10 is fixed by a fastening bolt 25, the axial housing of the first rotating body 20 ( 23, the second rotating body 30 is coupled, but is coupled by a bearing 32 in the bearing housing 33.

그리고, 회전축(2)에 결합된 제 1회전체(20)는 안전핀(21)에 의해 전동풀리(4)에 결합되고, 제 2회전체(30)는 고정핀(31)에 의해 전동풀리(4)에 결합된다.The first rotating body 20 coupled to the rotating shaft 2 is coupled to the electric pulley 4 by the safety pin 21, and the second rotating body 30 is connected to the electric pulley by the fixing pin 31. 4) is combined.

이때, 안전핀(21)과 고정핀(31)은 나사부가 형성된 볼트로 이루어지며, 이들이 결합되는 전동풀리(4)에는 각각의 나사공(4a)과 결합공(4b)이 형성된다.At this time, the safety pin 21 and the fixing pin 31 is made of a bolt formed with a screw portion, each of the screw holes 4a and coupling holes 4b are formed in the electric pulley 4 to which they are coupled.

도 4는 본 고안의 동력전달장치의 전동모터 과부하 방지장치의 사용 상태를 나타내는 측면도로서, 전동모터(M)의 회전축(2)에 과부하방지장치(10)에 의해 이중구조로 전동풀리(4)가 결합되고, 전동풀리(4)는 벨트(5)에 의해 종동풀리(6)와 연결된 상태에서, 종동풀리(6)에 과부하가 발생하게 되면, 정상적인 회전이 이루어지지 못하고, 전동모터(M)의 회전축(2)은 계속하여 회전하게 되지만, 피동력체의 종동풀리(6)가 정상적으로 회전되지 않게 되므로, 회전축(2)에 과부하가 발생하게 된다.4 is a side view showing a state of use of the electric motor overload protection device of the power transmission device of the present invention, the electric pulley (4) in a double structure by the overload prevention device 10 on the rotating shaft (2) of the electric motor (M) Is coupled, the electric pulley (4) is connected to the driven pulley (6) by the belt (5), when the overload occurs in the driven pulley (6), normal rotation is not made, the electric motor (M) The rotating shaft 2 of the rotating shaft continues to rotate. However, since the driven pulley 6 of the driven body does not rotate normally, an overload occurs on the rotating shaft 2.

이와 같이, 전동모터(M)가 정상적인 회전속도를 유지하며 회전되지 못하고, 과부하로 인해 과다한 하중이 가해지면서 저속으로 회전되거나 또는, 과부하로 인해 회전이 멈추게 되면, 전동모터(M)가 과열되면서 무리하게 구동되고, 장시간 과부하로 인한 과열 현상이 지속되면, 훼손되어 사용할 수 없게 될 우려가 있으나, 본 고안에 따른 과부하 방지장치(10)를 이용하게 되면, 과부하로 인해 전동풀리(4)가 정상적으로 회전되지 않더라도, 전동모터(M)의 회전축(2)은 과부하 없이 정상적인 회전이 가능한 것이다.As such, when the electric motor (M) is not rotated while maintaining a normal rotational speed, and the rotation is stopped at a low speed while the excessive load is applied due to the overload, or when the rotation is stopped due to the overload, the electric motor (M) is overheated If the overheat phenomenon due to overload for a long time is maintained, there is a risk of being damaged and unusable, but when using the overload protection device 10 according to the present invention, the electric pulley 4 is rotated normally due to overload Even if not, the rotating shaft 2 of the electric motor (M) is capable of normal rotation without overload.

예컨데, 전동풀리(4)에 과부하가 발생되면, 전동모터(M)의 회전축(2)이 과부하로 인해 순간적으로 비정상적인 회전상태를 이루게 되지만, 과부하 현상이 지속되지 않고 다시 정상적으로 회전하게 된다.For example, when the overload occurs in the electric pulley 4, the rotation shaft 2 of the electric motor (M) is an abnormal rotation state instantaneously due to the overload, but the overload phenomenon does not continue and rotates normally again.

이는 전동풀리(4)가 회전축(2)에 직접 결합되지 않고 과부하 방지장치(10)에 의한 이중구조로 결합되어 있으므로, 전동풀리(4)에 과부하가 발생되면, 회전축(2)의 회전력과 과부하로 인한 하중이 전동풀리(4)와 제 1회전판(24)을 결합하고 있는 안전핀(21)에 집중되면서, 안전핀(21)이 하중을 견디지 못하고 절단되어 결합상태가 해제된다.This is because the electric pulley 4 is not directly coupled to the rotating shaft 2, but is coupled in a double structure by the overload protection device 10. When the electric pulley 4 is overloaded, the rotational force and the overload of the rotating shaft 2 are overloaded. As a result of the load is concentrated on the safety pin 21 which couples the electric pulley 4 and the first rotating plate 24, the safety pin 21 is not able to withstand the load and is cut to release the engaged state.

따라서, 안전핀(21)에 의해 제 1고정판(24)과 전동풀리(4)의 결합상태가 해제되면, 제 1회전체(20)와 전동풀리(4)가 연동되지 않고 각각 분리된 상태를 이루게 되므로, 전동모터(M)의 회전축(2)이 전동풀리(4)와는 별도로 회전하게 되는 것이다.Therefore, when the coupling state of the first fixing plate 24 and the electric pulley 4 is released by the safety pin 21, the first rotating body 20 and the electric pulley 4 are not interlocked to achieve a separate state. Therefore, the rotating shaft 2 of the electric motor (M) is to be rotated separately from the electric pulley (4).

즉, 전동풀리(4)는 과부하로 인해 정상적인 회전이 이루어지지 않게 되더라도, 회전축(2)은 과부하 없이 정상적인 회전이 이루어지게 되므로, 전동모터(M)에는 과부하가 전혀 발생하지 않게 된다.That is, even if the electric pulley 4 is not rotated normally due to overload, the rotation shaft 2 is normally rotated without overloading, so that the overload does not occur at all in the electric motor M.

본 고안의 과부하 방지장치(10)는 위에서 언급한 바와 같이, 전동풀리(4)를 이용한 동력전달장치는 물론, 체인이나 기어방식에 의한 동력전달장치에서도 과부하방지를 위해 용이하게 사용할 수 있으며, 제 1회전체(20)를 고정하기 위한 안전핀(21)은 전동모터(M)의 사양에 따라, 과부하 방지를 위한 강도 및 사용수량이 조절되는 것으로, 적어도 2개 이상으로 사용자의 선택에 따라, 필요한 수량을 선택하여 사용할 수 있는 것이다.The overload protection device 10 of the present invention, as mentioned above, as well as the power transmission device using the electric pulley (4), can be easily used for the overload protection in the power transmission device by a chain or gear system, Safety pin 21 for fixing the rotating body 20 is to adjust the strength and quantity of use for preventing overload according to the specification of the electric motor (M), at least two or more according to the user's choice, The quantity can be selected and used.

이와 같이, 본 고안에 따른 동력전달장치의 전동모터 과부하 방지장치를 이용함에 따라, 전동모터를 이용하여 동력을 전달함에 있어, 전동모터의 회전축과 전동풀리가 직접 고정되지 않고, 이중 구조의 결합방식에 의해 결합되도록 함으로서, 전동모터에 발생되는 과부하 현상을 예방할 수 있어 동력전달에 따른 안정성과 효율성을 확보할 수 있으며, 특히, 과부하로 인해 전동모터가 훼손되어 사용수명이 단축되는 것을 방지함으로서, 사용수명을 장구히 할 수 있는 경제적인 효과를 얻을 수 있는 것이다. As such, according to the use of the electric motor overload prevention device of the power transmission device according to the present invention, in the transmission of power using the electric motor, the rotating shaft and the electric pulley of the electric motor is not directly fixed, the coupling scheme of the dual structure By being coupled by the, it is possible to prevent the overload phenomenon generated in the electric motor to ensure the stability and efficiency according to the power transmission, in particular, by preventing the electric motor is damaged by the overload to shorten the service life, The economic effect of long life can be achieved.
