본 고안은 전기디스크 그라인더류와 같이 베어링 하우징과, 팬가이드의 형상이 동일하거나 면접촉 조립되는 기계구조를 가진 제품에 적용한다.The present invention is applied to a product having a mechanical structure in which the bearing housing and the fan guide have the same shape or face contact assembly, such as electric disk grinders.
종래의 기술에 의한 각 부품의 용도를 도 1 및 도 2를 참고로 살펴보면 다음과 같다.Looking at the use of each component according to the prior art with reference to Figures 1 and 2 as follows.
베어링하우징(1)은 프레임(5)과 조립되어 구동부인 회전자(7)가 회전 및 정지시 프레임(5)으로 부터 이탈되지 않게 하는 부품이고, 베어링(2)은 일반적인 용도와 같이 베어링하우징(1)에 고정되어 회전자(7)의 회전을 원활하게 하는 부품이며, 팬가이드(3)는 프레임(5)에 고정되며 팬(4)의 회전시 팬(4)의 이탈 방지 역할을 하고 동시에 통풍량 및 토풍방향을 결정하는 부품이다. 즉 세 개의 부품으로 각각 구성되며, 사용재질도 다르다. 그리고 단일부품을 조립하였을 때 균일한 품질을 얻기 힘들다.The bearing housing 1 is a component that is assembled with the frame 5 to prevent the rotor 7, which is a driving part, from being separated from the frame 5 when rotating and stopping, and the bearing 2 has a bearing housing ( It is fixed to 1) is a component to smooth the rotation of the rotor (7), the fan guide (3) is fixed to the frame (5) and serves to prevent the separation of the fan (4) during the rotation of the fan (4) It is a part that determines the ventilation volume and the air flow direction. That is, it consists of three parts, and the material used is also different. And it is hard to get uniform quality when assembling a single part.
즉 도 2와 같이, 팬가이드(3)는 프레임(5) 내측에 고정되어 팬(4)의 회전시 가이드역할을 하며 동시에 통풍량의 누설 및 통풍방향을 결정한다. 그리고 베어링 하우징(1)은 베어링(2)과 조립되어 회전자(7) 회전시 위치 및 프레임(5)과 조립되어 이탈을 방지한다. 조립순서는 프레임(5)에 고정자(6)를 조립하고, 회전자(7)를 조립하며, 팬가이드(3)를 조립하고, 베이링(2)을 조립하며, 베어링하우징(1)을 조립한다.That is, as shown in Figure 2, the fan guide 3 is fixed to the inside of the frame 5 serves as a guide during the rotation of the fan 4 and at the same time determines the leakage and ventilation direction of the ventilation amount. And the bearing housing (1) is assembled with the bearing (2) is assembled with the position and the frame (5) when the rotor 7 rotates to prevent separation. The assembly sequence is to assemble the stator (6) to the frame (5), to assemble the rotor (7), to assemble the fan guide (3), to assemble the bearing (2), and to assemble the bearing housing (1). do.
종래의 기술에 의한 세 개의 부품을 조립하는 구조는 베어링 하우징(1)에 베어링(2)을 압입시 파손을 일으켜 제품소음발생의 원인이 되고, 팬가이드(3)의 재질이 철판이기에 제품의 끝부분에 버어가 발생되어 조립시 안전사고 발생이 야기될수 있으며, 균일한 치수관리가 어렵고, 여러 가지 재질 및 제조공정을 통한 조립공차가 발생하며, 팬가이드(3)의 유동이 발생할수 있는 문제점이 있는 바, 본 고안의 목적은 상기와 같은 문제점을 고려하여 안출한 것으로, 금형구조를 개선하여 베어링을 인서트후 베어링하우징을 사출하므로 압입공정시 발생되는 부분을 개선할수 있고, 각각 부품별 조립공정을 없애고 일체로 형성하므로 치수관리가 용이하고, 조립공차를 최소화할수 있으며, 허용공차를 최소화하므로 팬가이드의 유동현상을 보완하도록 한 일체형 베어링하우징을 제공함에 있다.The structure of assembling three parts according to the prior art causes damage when press-fitting the bearing 2 into the bearing housing 1, causing noise, and the end of the product because the material of the fan guide 3 is steel plate. Burrs are generated in the part, which may cause safety accidents during assembly, uniform dimension management is difficult, assembly tolerances occur through various materials and manufacturing processes, and the flow of the fan guide 3 may occur. The purpose of the present invention is to conceive in view of the above problems, and by improving the mold structure, the bearing housing is injected after inserting the bearing, thereby improving the parts generated during the indentation process, and the assembly process for each part. As it is removed and formed integrally, dimension management is easy, assembly tolerance can be minimized, and tolerance can be minimized, so that the integrated phenomenon of fan guide is compensated for. To provide a bearing housing.
