Description

공랭 기능이 향상된 공기압축기{Air compressor with improved air cooling function}Air compressor with improved air cooling function

본 발명은 공기압축기의 압축펌프 및 모터를 개별 냉각방식으로 냉각하여 공랭효과를 획기적으로 향상하고, 대용량의 다기능 에어클리너를 이용하여 상기 압축펌프의 가동시 발생하던 소음을 줄여줌과 동시에 흡입공기를 말끔하게 정화하는 기술에 관한 것이다.The present invention significantly improves the air cooling effect by cooling the compression pump and the motor of the air compressor in a separate cooling method, and reduces the noise generated during operation of the compression pump by using a large-capacity multi-function air cleaner and at the same time intake air It's about the cleansing technique.

근자에 들어 피스톤식 공기압축기의 콤팩트한 구조 및 소형화, 경량화를 구현하기 위한 방안으로 공기압축펌프와 이 공기압축펌프를 가동하기 위한 모터를 일체로 직결시킨 공기압축기가 제안되고 있으며, 상기 모터 직결식 공기압축기는 통상적으로 흡입밸브가 구비된 실린더 헤드의 측면 통기구에 에어클리너를 설치하게 된다.In order to realize the compact structure, miniaturization, and light weight of a piston type air compressor, an air compressor that directly connects an air compression pump and a motor for operating the air compression pump has been proposed. The air compressor is typically provided with an air cleaner in the side vent of the cylinder head provided with a suction valve.

그러나 상기 모터 직결식 공기압축기의 모터는 고속으로 회전함에 따라 더욱 큰 용량의 에어클리너가 필요함에도 종래에는 압축실린더에 설치된 각각의 실린더 헤드마다 개별적인 소형 에어클리너를 사용함으로써 매우 불편할 뿐만 아니라 용량이 더 큰 에어클리너를 장착하는데 어려움이 있어 이보다는 상기 압축실린더의 개수만큼 여러 개의 에어클리너가 아닌 대용량을 갖는 단일 구조로 이루어진 에어클리너장치를 사용하는 것이 더욱 바람직하다 할 수 있다.However, although the motor of the motor-directed air compressor rotates at a high speed, a larger capacity air cleaner is required, but it is very inconvenient to use a separate small air cleaner for each cylinder head installed in the compression cylinder. Since it is difficult to mount an air cleaner, it may be more preferable to use an air cleaner device having a single structure having a large capacity rather than several air cleaners as many as the number of the compression cylinders.

또한, 상기 모터 직결식 공기압축기는 실린더 헤드를 통해 피스톤이 상하로 작동하는 압축실린더의 내부로 외부공기를 흡입하여 압축하는 과정에서 상기 실린더 헤드에서 심한 소음이 발생한다.In addition, the motor-directed air compressor generates a lot of noise in the cylinder head in the process of sucking and compressing the outside air into the inside of the compression cylinder that the piston operates up and down through the cylinder head.

이러한 문제점을 적극적으로 해소하기 위한 선행기술로서, 본 발명의 출원인에 의해 선출원 된 「특허출원 제2009-105779호, 명칭/공기압축기용 다기능 흡입머플러」가 제안되고 있다.As a prior art for actively solving such a problem, "Patent Application No. 2009-105779, Name / Multifunctional Suction Muffler for Air Compressor" proposed by the applicant of the present invention has been proposed.

이와 같은 선행기술은 외부공기가 다기능 흡입머플러의 내부를 경유하여 실린더 헤드로 흡입됨으로써 외부공기의 흡입?압축과정에서 발생하는 소음을 획기적으로 줄여줌은 물론 공기에 함유된 먼지 및 불순물을 말끔하게 정화하는 유용한 효과를 제공한다.This prior art dramatically reduces the noise generated during the suction and compression process of the external air as well as cleans the dust and impurities contained in the air by sucking the external air into the cylinder head via the inside of the multifunctional suction muffler. To provide useful effects.

그러나 상기한 선행기술은 도면 6과 같이 모터(1)의 반 부하 측 모터축(2)에 설치된 하나의 냉각팬(3)을 이용하여 상기 모터(1)와 압축펌프(4)를 동시에 냉각함으로써 상기 냉각팬(3)과 근접한 모터(1)는 어느 정도 냉각이 이루어지나, 상기 모터(1)는 오히려 압축펌프(4)로 전달되는 냉각풍의 진행경로를 방해함에 따라 냉각풍이 제대로 전달되지 않아 압축펌프의 냉각효율이 현저하게 저하되고 있는 실정이다.However, the above-described prior art cools the motor 1 and the compression pump 4 simultaneously by using one cooling fan 3 installed on the motor shaft 2 of the half load side of the motor 1 as shown in FIG. The motor 1 in close proximity to the cooling fan 3 is cooled to some extent, but the motor 1 is not compressed because the cooling wind is not properly transmitted as it interferes with the traveling path of the cooling wind delivered to the compression pump 4. The cooling efficiency of the pump is significantly reduced.

본 발명은 상기한 선행기술에 따른 공기압축기가 내포하고 있는 제반 문제점을 적극적으로 해소하기 위한 것으로, 모터의 반 부하 측에 설치된 모터 냉각팬을 이용하여 모터를 전용으로 냉각함과 동시에 상기 모터의 부하 측에 설치된 별도의 펌프 냉각팬을 이용하여 압축펌프를 개별 냉각할 수 있도록 함을 발명의 해결과제로 한다.The present invention is to actively solve all the problems of the air compressor according to the prior art described above, by using a motor cooling fan installed on the half-load side of the motor to cool the motor exclusively and at the same time the load of the motor It is an object of the present invention to separately cool a compression pump by using a separate pump cooling fan installed at the side.

또한, 본 발명은 실린더 헤드로 공급되는 외부공기가 상기 모터의 상단에 설치된 다기능 에어클리너를 경유하면서 흡입?압축과정에서 발생하는 소음을 줄여 줄수 있도록 함을 발명의 또 다른 해결과제로 한다.In addition, another object of the present invention is to reduce the noise generated during the suction and compression process while the external air supplied to the cylinder head via the multi-function air cleaner installed on the top of the motor.

본 발명은 상기한 과제를 해결하기 위한 수단으로, 상기 모터의 반 부하 측 모터축에 모터 냉각팬을 설치하고, 상기 모터의 부하 측 모터축에 압축펌프를 직결 설치하되 상기 모터축은 압축펌프의 크랭크실을 관통하여 외부로 노출 설치하며, 상기 크랭크실을 관통하여 외부로 노출된 모터축에 펌프 냉각팬을 설치하는 기술을 강구한다.The present invention is a means for solving the above problems, by installing a motor cooling fan on the motor side of the half-load side of the motor, and directly installed a compression pump on the load-side motor shaft of the motor, the motor shaft is a crank of the compression pump Through the seal and exposed to the outside installation, the technology to install a pump cooling fan on the motor shaft exposed through the crank chamber to the outside.

본 발명에 따르면, 모터 냉각팬은 모터만을 전용으로 냉각함과 동시에 펌프 냉각팬은 압축펌프를 전용으로 냉각하는 혁신적인 개별 공랭을 구현함으로써 상기 모터 및 압축펌프를 더욱 효율적으로 냉각하여 압축공기의 생산성을 획기적으로 향상하는 효과를 제공한다.According to the present invention, the motor cooling fan cools only the motor and at the same time the pump cooling fan implements the innovative individual air cooling to the dedicated compression pump to cool the motor and the compression pump more efficiently to improve the productivity of the compressed air.

본 발명이 해결하고자 하는 과제의 해결수단을 보다 구체적으로 구현하기 위한 바람직한 실시 예에 대하여 설명하기로 한다.Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

본 발명의 바람직한 실시 예에 따른 전체적인 기술구성을 첨부된 도면에 의거 개략적으로 살펴보면, 모터(10)의 부하 측에 압축펌프(20)가 직결된 공기압축기(A)에 있어서,Looking at the overall technical configuration according to the accompanying drawings in accordance with a preferred embodiment of the present invention, in the air compressor (A) in which the compression pump 20 is directly connected to the load side of the motor 10,

상기 모터(10)의 반 부하 측 모터축(11)에 모터 냉각팬(12)이 설치되고; 상기 모터(10)의 부하 측 모터축(11)은 압축펌프(20)의 크랭크실(21)을 관통하여 외부로 노출 설치되며; 상기 크랭크실(21)을 관통하여 외부로 노출된 부하 측 모터축(11)에는 압축펌프(20)를 전용으로 냉각하는 펌프 냉각팬(30)이 설치된 유기적인 결합구성으로 이루어짐을 알 수 있다.A motor cooling fan 12 is installed at the half-load side motor shaft 11 of the motor 10; The load side motor shaft 11 of the motor 10 is exposed to the outside through the crank chamber 21 of the compression pump 20; It can be seen that the load-side motor shaft 11 penetrating the crank chamber 21 to the outside is made of an organic coupling configuration in which a pump cooling fan 30 for exclusively cooling the compression pump 20 is installed.

이하, 상기 개략적인 구성으로 이루어진 본 발명을 실시 용이하도록 좀더 상세하게 설명하기로 한다.Hereinafter, the present invention having the above-described schematic configuration will be described in more detail for facilitating the implementation.

우선적으로 본 발명은 모터(10)의 부하 측에 압축펌프(20)가 직결된 공기압축기(A)에 적용됨을 전제로 하며, 상기 공기압축기(A)의 모터(10)는 반 부하 측의 외부로 노출된 모터축(11)에 상기 모터(10)만을 전용으로 냉각할 수 있는 모터 냉각팬(12)이 설치된다.First of all, the present invention is based on the premise that the compression pump 20 is directly applied to the air compressor A directly connected to the load side of the motor 10, and the motor 10 of the air compressor A is external to the half load side. A motor cooling fan 12 capable of exclusively cooling the motor 10 is installed on the exposed motor shaft 11.

상기 모터(10)의 부하 측 모터축(11)은 공지된 기술과 같이 직결된 압축펌프(20)의 크랭크실(21) 내부로 연결되고, 외측에는 바로크랭크축(6)이 끼움 설치된다.The load-side motor shaft 11 of the motor 10 is connected to the inside of the crank chamber 21 of the compression pump 20 directly connected as known in the art, the bar crank shaft 6 is fitted to the outside.

여기에서 본 발명은 상기 부하 측의 모터축(11)이 단지 상기 크랭크실(21)의 내부에 머무르는 것에 지나지 않고, 도 2에 도시된 바와 같이 상기 크랭크실(21)의 내부를 관통하여 외부로 노출되는 핵심기술이 접목된다.In the present invention, the motor shaft 11 on the load side merely stays inside the crank chamber 21, and as shown in FIG. 2, the inner side of the crank chamber 21 penetrates to the outside. The core technology that is exposed is combined.

따라서, 상기 크랭크실(21)을 관통하여 외부로 노출되는 부하 측의 모터축(11)에는 압축펌프(20)를 전용으로 공랭할 수 있는 펌프 냉각팬(30)의 설치가 가능함으로써 상기 한 쌍의 모터 냉각팬(12) 및 펌프 냉각팬(30)을 이용하여 각각 모터(10) 및 압축펌프(20)를 개별 냉각방식으로 공랭하면서 냉각효율을 획기적으로 향상하는 특별한 효과를 제공하며, 이로 인해 공기압축기(A)의 압축성능 향상을 제고할 수 있게 된다.Therefore, the pair of pump cooling fans 30 capable of air-cooling the compression pump 20 exclusively can be installed in the motor shaft 11 on the load side exposed through the crank chamber 21 to the outside. By using the motor cooling fan 12 and the pump cooling fan 30 of the air cooling of the motor 10 and the compression pump 20 in a separate cooling method, respectively, it provides a special effect of significantly improving the cooling efficiency, thereby It is possible to improve the compression performance of the air compressor (A).

이와 같은 크랭크실(21)은 도 2에 도시된 바와 같이 일측의 개방부(22)에 오일씰 브라켓(23)이 막음 설치되고, 상기 오일씰 브라켓(23)에는 크랭크실(21) 내의 오일이 외부로 누출됨을 방지하는 오일씰(24)을 설치할 수 있는 오일씰 설치공(25)이 상기 크랭크실(21)의 내외부로 연통하도록 관통 설치된다.As shown in FIG. 2, the crank chamber 21 is installed with an oil seal bracket 23 blocked at an opening 22 of one side, and oil in the crank chamber 21 is externally installed at the oil seal bracket 23. An oil seal installation hole 25 capable of installing an oil seal 24 to prevent leakage is installed to communicate with the inside and outside of the crank chamber 21.

따라서, 상기 부하 측의 모터축(11)은 상기 오일씰 설치공(25)에 끼움 설치된 오일씰(24)을 관통하여 외부로 노출된 상태를 유지함에도 회전작동이 원활함은 물론 누유 발생을 억제할 수 있게 된다.Therefore, the motor shaft 11 on the load side can penetrate the oil seal 24 installed in the oil seal installation hole 25 and maintain the exposed state to the outside, while also smoothly rotating the operation and can suppress leakage. Will be.

또한, 본 발명은 상기 오일씰 브라켓(23)의 상부에 크랭크실(21)의 내외부로 연통하는 에어브리더(27)가 추가로 설치됨으로써 상기 크랭크실(21)에 누설되는 압력을 외부로 배출하여 압축펌프(20)의 원활한 작동을 보장하는 효과를 제공한다.
In addition, according to the present invention, an air breather 27 communicating with the inside and the outside of the crank chamber 21 is additionally installed on the upper portion of the oil seal bracket 23 to discharge the pressure leaked into the crank chamber 21 to the outside and compress the outside. It provides the effect of ensuring the smooth operation of the pump 20.

한편, 본 발명은 외부공기의 흡입?압축과정에서 발생하는 소음을 저감함과 동시에 공기를 말끔하게 정화할 수 있는 대용량을 갖는 단일체의 다기능 에어클리너(40)가 상기 모터(10)의 상단에 안착되는 기술이 추가로 접목된다.On the other hand, the present invention is a monolithic multi-function air cleaner 40 having a large capacity capable of reducing the noise generated during the suction and compression process of the external air at the same time to clean the air neatly seated on the top of the motor 10 Technology is additionally incorporated.

이를 위한 다기능 에어클리너(40)는 모터(10)를 인양하거나 이동할 수 있도록 상기 모터(10)의 상단에 형성된 인양고리 체결부(14)에 나사결합된 통상의 인양고리(7)를 제거한 후 상기 인양고리 체결부(14)에 안정적으로 조립 설치함으로써 설치공간에 어떠한 제약을 받지 않고 상기 모터(10)와 일체화된 세트화를 이룰 수 있게 된다.The multi-function air cleaner 40 for this purpose is to remove the conventional lifting ring (7) screwed to the lifting ring fastening portion 14 formed on the top of the motor 10 to lift or move the motor (10) By assembling and installing the lifting ring fastening portion 14 stably, it is possible to achieve an integrated set with the motor 10 without any limitation in the installation space.

즉 본 발명은 모터(10) 상단의 인양고리(7)를 제거한 후 인양고리 체결부(14)에 스터드볼트(41)가 수직상으로 나사결합 설치되고, 상기 스터드볼트(41)의 외측에는 필터 하우징(42)이 끼움 설치된 후 상기 스터드볼트(41)에 너트(47)가 체결됨으로써 필터 하우징(42)은 스터드볼트(41)와 일체화된 조립상태를 유지하며, 상기 필터 하우징(42)은 상부가 개방되고 상하 측에 각각 휠터 삽입부(42a) 및 흡기터미널(42b)이 형성된다.That is, according to the present invention, after removing the lifting ring 7 of the upper end of the motor 10, the stud bolt 41 is vertically screwed to the lifting ring fastening portion 14, and the filter is disposed outside the stud bolt 41.
