Abstract

본 발명은 플라스틱 재료로 만들어진 소형 모우터용 하우징에 관한 것이다.The present invention relates to a housing for a small motor made of a plastic material.

주지하는 바와 같이 소형 모우터의 하우징으로는 주로 알루미늄 다이케스팅으로 된 것과 플라스틱으로 된 것이 사용되고 있다.As is known, housings of small motors are mainly made of aluminum die casting and plastic.

종래의 알루미늄 다이캐스팅으로 된 소형 모우터용 하우징은 동심도 및 진원도 저하를 교정하기 위하여 반드시 후가공 작업을 추가로 실시하여야 하는 것이어서 생산성이 저하되는 문제점이 있는 것이다.The conventional housing for a small motor made of aluminum die casting has a problem in that productivity is reduced since additional work must be additionally performed to correct concentricity and roundness reduction.

또한 플라스틱으로 된 모우터 하우징도 사용되기는 하였으나, 이는 그 재질의 특성상 진원도 및 동심도를 높이기 위한 후가공이 사실상 불가능한 문제점이 있는 것이다.In addition, although a plastic motor housing was also used, this is a problem in that the post-processing to increase the roundness and concentricity is virtually impossible due to the characteristics of the material.

본 발명은 모우터 하우징의 재질을 플라스틱으로 선택하되 이의 보스 내주면에 진원도와 동심도를 충족시켜 줄 수 있는 리브를 설치하여 줌으로써 별도의 교정작업을 실시하지 않더라도 충분한 진원도와 동심도를 얻을 수 있도록 하여서 된 것이다.The present invention is to select the material of the motor housing plastic, but by installing a rib that can satisfy the roundness and concentricity on the inner circumferential surface of the boss so that sufficient roundness and concentricity can be obtained even without performing a separate calibration work .
