Abstract

〔목적〕〔purpose〕

이 발명은 고도의 정밀도를 요구하는 플라스틱 베어링에 있어서, 엔지니어링 플라스틱내에 열전도율이 높은 물질을 삽입하고 이를 통해 고른 열방출로써 베어링의 변형을 방지하며 삽입물이 지주 역할을 하도록 하여 외압에 대한 저항력을 높일 수 있도록 한 고정밀도 플라스틱 베어링에 관한 것이다.The present invention is to insert a high thermal conductivity material into the engineering plastic in the plastic bearings that require a high degree of precision, thereby preventing the deformation of the bearing by even heat dissipation and to increase the resistance to external pressure by making the insert act as a support To a high precision plastic bearing.

〔구성〕〔Configuration〕

이 발명은 고정밀도의 플라스틱 베어링을 제작함에 있어서, 베어링(1)의 내부에 여러개의 방사상 지지편(2)을 형성하고, 상기 베어링(1)의 중공부(3)에는 연전도율이 우수한 재질의 삽입 지지구(4)를 일체형으로 삽입 설치하되, 이 삽입 지지구(4)의 외주는 상기 각 지지편(2) 사이에 삽입 지지되도록 하며, 상기 삽입 지지구(4)의 상,하단에는 상기 베어링(1)의 상,하를 지지하도록 하는 지지턱(5)을 형성하는 고정밀도 플라스틱 베어링을 구성한 것이다.In the present invention, in manufacturing a plastic bearing of high precision, a plurality of radial support pieces (2) are formed inside the bearing (1), and the hollow portion (3) of the bearing (1) is made of a material having excellent electric conductivity. The insertion support 4 is inserted and installed in one piece, and the outer circumference of the insertion support 4 is inserted and supported between the support pieces 2, and the upper and lower ends of the insertion support 4 are It constitutes a high-precision plastic bearing forming the support jaw (5) to support the upper and lower of the bearing (1).
