Description

횡류팬용 구동허브 및 그 제조방법{The drive hub for use abreast fan and the manufacture method}Drive hub for cross flow fan and manufacturing method thereof {The drive hub for use abreast fan and the manufacture method}

본 발명은 횡류팬용 구동허브 및 그 제조방법에 관한 것으로, 합성수지로 사출성형되는 횡류팬의 축경부에 인서트사출되어 조립되는 수지재의 구동허브 및 그 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drive hub for a cross flow fan and a method for manufacturing the same, and to a drive hub for a resin material which is inserted and injected into the shaft diameter portion of a cross flow fan injection molded with a synthetic resin, and a method for manufacturing the same.

상기와 같은 구동허브는 횡류팬 뿐만 아니라, 선풍기나 각종 송풍기 등을 비롯한 각종 공기조화장치의 구동허브로 모터의 구동축을 횡류팬의 축경부에 보다 경제적이고, 용이하고 정밀도가 높은 구동허브를 제공하고자 하는 것이다. The driving hub as described above is a driving hub of various air conditioning devices including a fan and various blowers, as well as a cross flow fan, in order to provide a more economical, easy and high precision drive hub to the shaft diameter of the cross flow fan. It is.

전통적으로 에어컨디셔너를 비롯한 횡류팬의 축경부와 연결하는 구동허브는 쾌삭황동재나,알루미늄봉재를 자동선반가공과 너링 등의 가공수단을 거쳐 완성 제공하기 때문에 그 제조원가가 높아지고 있는 실정이다.Traditionally, driving hubs that connect to the shafts of cross-flow fans, including air conditioners, provide high-quality brass and aluminum rods through processing such as automatic lathes and knurling.

이와 같은 횡류팬은 직경에 비해 길이가 긴 휠팬의 일종으로 일단부에는 구동모터가 장착되고 이단부에는 횡류팬의 축경부에 고정지지된 회전축이 베어링체내에서 회전가능하게 장착된다.Such a cross flow fan is a kind of wheel fan having a length longer than its diameter, and a driving motor is mounted at one end thereof, and a rotating shaft fixed to the shaft diameter portion of the cross flow fan is rotatably mounted in the bearing body at one end thereof.

참고로 횡류팬은 축경부의 구동모터축과 다른 일단부에 고정지지된 베어링체 에 조립되는 회전축과의 정렬이 매우 정밀하지 않으면, 팬이 흔들리거나 소음이 발생되는 원인이 된다.For reference, if the cross-flow fan is not very precisely aligned with the drive motor shaft of the shaft diameter part and the rotating shaft assembled to the bearing body fixed to the other end, the fan may shake or generate noise.

횡류팬중 에어컨디셔너에 적용되는 국내시장 수요량은 국내 L사 1,200만대,S사 80만대, D사 50만대, 기타 100만대로 국내 시장수요량은 1,430만대에 이르고 있음을 감안하여, 상기와 같은 종래 쾌삭황동재의 매입단가는 780원, 알루미늄재는 510원임에 반하여, 수지재 구동허브를 350원선으로 가격을 제시하더라도 원가절감은 2,288 백만원에 이른다.Domestic market demand for air conditioners in cross flow fans is 12 million units in Korea, 800,000 units in S company, 500,000 units in D company, and 1 million units in Korea. While the purchase price of ash is 780 won and aluminum is 510 won, the cost reduction of 2,288 million won is possible even if the price of the resin driving hub is 350 won.

그러나, 위와 같은 경제적 이익 외에도 국내 L사의 경우는 중국에서 100% 수입하고, 기타는 원재료 수입후 국내가공을 거치는 실정을 감안하면, 구동허브를 수지로 생산 제공함으로써, 비철금속에 비해 원가절감율을 30%선으로 달성시키고, 무게의 감소로 인해 물류비를 감소시키고, 원재료의 원활한 수급으로 생산C/T단축으로 생산성을 향상시키며, 제품의 다변화로 국내외 환경변화에 따른 리스크를 감소시키는 효과를 내기 위해서는 수지재 구동허브 채택을 현실화하여야 한다.However, in addition to the above economic benefits, domestic L companies import 100% from China, and other domestic raw materials are imported and processed, and production of driving hubs is made of resin, which provides 30% cost reduction compared to nonferrous metals. Resin material to achieve the effect of reducing the cost of logistics by reducing the weight, reducing the logistics cost by reducing the weight, improving production C / T by smooth supply and demand of raw materials, and reducing the risk of environmental changes at home and abroad by diversifying products. Drive hub adoption must be realized.

위와 같은 분야의 선원기술로는 다음과 같다. The source technology of the above fields is as follows.

대한민국 등록실용신안 제20-233977호에 따르면, 합성수지재로 이루어지며, 중심부에 관통내경이 형성되되,관통내경의 일측에 단턱이 형성된 D-커팅부가 구동모터의 D-커팅결합되는 보스인서트;상기 보스인서트 일측 외주면에 접합되어 동력전달시의 진동을 흡수하는 고무재질의 방진부재; 상기 보스인서트와 방진부재를 경유하여 전달된 구동모터의 회전력을 팬블로어측으로 전달하는 동력전달부재를 포함하는 에어콘용 팬보스에 관한 것인데, 상기에서와 같이 보스인서트와 고무재방진부 재를 결합하기 위해 보스인서트 외경축부에 형성된 다수개의 충진홀 등이 마련된 체 사출형성되는 보스인서트에 있어서 문제는 생산후 수축을 방지하기 위해, 냉각시키는 과정에서 센터의 정밀도가 나오지 않아 불량처리되는 점이 많다. According to the Republic of Korea Utility Model Registration No. 20-233977, made of a synthetic resin material, a through-inner is formed in the center, the boss insert is a D-cutting part of the driving motor D-cutting part is formed on one side of the penetrating inner diameter; A dustproof member made of a rubber material which is joined to an outer circumferential surface of the boss insert and absorbs vibrations during power transmission; It relates to a fan boss for an air conditioner including a power transmission member for transmitting the rotational force of the drive motor transmitted via the boss insert and the dustproof member to the fan blower side, as described above to combine the boss insert and the rubber dustproof member The problem in the boss insert formed by injection molding a plurality of filling holes and the like formed in the outer diameter shaft portion of the boss insert is often poor because the precision of the center does not come out during the cooling process to prevent shrinkage after production.

한편, 국내 대한민국 등록특허 제10-373479호에 제시된 구동허브 및 횡류팬 조립체는 모터의 구동축을 횡류팬조립체에 연결시키는 일편의 구동허브에 관한 것으로, 상기의 구동허브는 중앙 슬리브와 외경잠금구간에 다이어프램으로 이루어지고, 상기 구동허브를 횡류팬조립체의 구동단부판에 조립하는 것은 구동허브와 구동단부판이 상호 작용하는 잠금부재를 별도의 공구로 조립하는 것으로, 상기 구동허브는 다이아프램을 가요성 있게 비틀리도록 열가소성 중합체로 제조하도록 한 것이다.On the other hand, the drive hub and the crossflow fan assembly presented in the Republic of Korea Republic of Korea Patent No. 10-373479 relates to a drive hub for connecting the drive shaft of the motor to the crossflow fan assembly, the drive hub in the center sleeve and the outer diameter locking section Composed of a diaphragm, and assembling the drive hub to the drive end plate of the cross-flow fan assembly is to assemble the locking member in which the drive hub and the drive end plate interact with a separate tool, the drive hub is flexible to the diaphragm It is made of a thermoplastic polymer to twist.
