본 고안은 회전되는 축을 지지하는 베어링이 마찰로 인한 마모 및 마멸등으로 고장이 생기는 것을 진단할 수 있는 청음기에 관한 것으로, 특히 탐촉자의 내부에 형성된 다이나믹 마이크로폰으로 흡수되는 것을 증폭기에서 증폭된 음을 레시버로 청취함과 동시에 이에 순차 점등용 표시등에 감지되도록 형성함으로써 베어링 고장 진단시 낮은음을 증폭기로 증폭하여 회전체를 확인하면서 레시버로 청취 및 주파수를 전압으로 변환하여 표시되는 표시등으로 판단하므로 인해 정확도 및 안전사고등을 미연에 방지할 수 있도록한 베어링 고장 진단용 청음기에 관한 것이다.The present invention relates to a hearing aid that can diagnose the failure of the bearing supporting the rotating shaft due to frictional wear and wear, especially the sound amplified by the amplifier that is absorbed by the dynamic microphone formed inside the transducer. It is configured to listen to the indicator at the same time and to be detected by the indicator lights for sequential lighting.In the case of bearing failure diagnosis, amplify the low sound with an amplifier and check the rotating body, and the receiver judges that the indicator is displayed by converting the frequency into voltage and displaying the accuracy. And a hearing aid for diagnosing bearing failures to prevent safety accidents.
종래 일반적인 청음기는 베어링 고장등을 진단할때 청음봉을 이용하여 진단하였는데 베어링의 낮은 소리를 직접 청음봉의 한쪽끝을 귀에 밀착하여 청음함으로써 청음봉의 청음 전달 감쇠가 많이 일어나 측정하는 사람마다 진단소리를 느끼는 감각이 다르므로 인해 고장 진단을 쉽게 판단하기 어려울 뿐만아니라 회전물체를 확인하면서 진단할 수 없어 불편함과 번거로움등으로 안전사고의 위험등이 항상 동반되는 많은 문제점이 발생되었다.Conventional hearing aids are diagnosed by using a sound bar when diagnosing a bearing failure, etc. The low sound of the bearing is directly audible to one end of the sound bar, so that the sound transmission attenuation of the sound bar is high. Due to the different sensations, it is difficult to determine the diagnosis of the fault easily, and it is not possible to diagnose the problem while checking the rotating object, resulting in many problems that are accompanied by the risk of safety accidents due to inconvenience and hassle.
본 고안은 이와같은 문제점을 감안하여, 탐촉자를 이용한 증폭기의 증폭된 음을 레시버로 청취함과 동시에 표시등으로 감지되도록 하고 또 회전물체를 확인하면서 판단할 수 있도록한 베어링 고장 진단용 청음기를 안출한 것으로, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.In view of the above problems, the present invention was designed to listen to the amplified sound of the amplifier using the transducer and to listen to the indicator at the same time, and to detect the bearing failure to make a judgment while checking the rotating object. This will be described in detail with reference to the accompanying drawings.
전단에 탐촉자(1)가 형성됨과 아울러 중앙에 증폭기 케이스(2)가 형성되고 후단에 레시버 단자케이스(3)가 위치되게 형성하여, 탐촉자(1)의 내부공간을 전협후광으로 형성하되 내벽면에 요철면을 형성하여 흡음제로 처리하며 직진음파를 흡수할수 있게 다이나믹 마이크로폰(4)를 착설하고 증폭기 케이스(2) 내부의 증폭기(5)에서 증폭된 음을 청취할 수 있게 단자케이스(3)에 레시버(7)를 장설하였고, 증폭기케이스(2)의 외측에 수개의 순차 점등용 표시등(6)을 장설하여서된 것이다.The transducer 1 is formed at the front end, and the amplifier case 2 is formed at the center and the receiver terminal case 3 is positioned at the rear end, so that the inner space of the transducer 1 is formed as a total narrow back light. A dynamic microphone 4 is installed to form an uneven surface on the surface of the terminal case 3 so as to be treated with a sound absorbing agent and absorb linear sound waves, and to listen to the amplified sound from the amplifier 5 inside the amplifier case 2. The receiver 7 was installed, and several indicator lights for sequential lighting were installed outside the amplifier case 2.
미설명부호 8은 전원스위치이다.Reference numeral 8 denotes a power switch.
이와같이 구성된 본 고안은 베어링의 낮은 진동음을 탐촉자(1)에 직접 전달됨과 동시에 이 탐촉자(1)의 전달음은 내부의 공간을 전협후광으로 만들어진 벽면에 삼각형 모양의 요철을 만든후 흡음제로 처리하여 잔음을 최소화시켜 진단음이 직접 탐촉자(1) 후면의 다이나믹 마이크로폰(4)의 진동판을 진동시킴으로써 전기적인 신호로 변환되어 증폭기(5)에서 충분히 음으로 증폭된 진단의 소리가 레시버(7)로 전달되어 청취할 수 있는 것이다.According to the present invention configured as described above, the low vibration sound of the bearing is directly transmitted to the transducer 1, while the sound of the transducer 1 is made of triangular irregularities on the wall made of all-intensity halo, and then treated with a sound absorbent to provide residual noise. The diagnostic sound is directly converted into an electrical signal by vibrating the diaphragm of the dynamic microphone 4 at the rear of the transducer 1 so that the sound of the diagnosis sufficiently amplified by the amplifier 5 is transmitted to the receiver 7. You can listen.
또한, 부가적으로 증폭된 신호를 주파수 성분에 따른 전압신호로 바꾸어 각 전압 신호의 크기에 따라 표시등(6)의 수가 순차적으로 점등되도록 하여 현재 진단 상태의 표시등(6)의 수와 차후의 진단상태의 표시등(6)의 점등수를 비교하면 차후의 진단 상태를 현재 결과와 비교측정할 수 있는 것이다.Further, the additionally amplified signal is converted into a voltage signal according to the frequency component so that the number of indicators 6 is sequentially turned on in accordance with the magnitude of each voltage signal so that the number of indicators 6 in the current diagnosis state and the subsequent By comparing the number of lights of the indicator 6 in the diagnosis state, the subsequent diagnosis state can be compared with the current result.
이상과 같이 본 고안은 간단한 구조와 간편한 작동에 의해 청음기를 이용하여 베어링 고장을 진단할때 진단의 낮은음을 증폭기로 증폭하여 회전체를 확인하면서 레시버로 청취할 수 있도록 하고 또한 주파수를 전압으로 변환하여 표시등으로 표시하여 식별 및 판단하므로써 정확도와 고장정도 및 안전사고등을 미연에 방지할 수 있는 효과가 있는 것이다.As described above, the present invention amplifies the low sound of the diagnosis by an amplifier by amplifying the low sound of the diagnosis by the amplifier when the bearing failure is diagnosed by the simple structure and the simple operation, and the frequency is converted into the voltage by listening to the receiver. By identifying and judging by indicators, it is possible to prevent accuracy, failure degree and safety accidents in advance.
