Abstract

반구형 베어링 및 그 제조방법에 관한 내용이 개시되어 있다. 기동 및 정지할 대 마찰에 의해 발생되는 마모를 최대한 방지할 수 있는 반구형 유체 베어링 및 그 제조방법을 제공하기 위하여 축에 고정된 상반구와 하반구, 그리고 상기 상반구 및 하반구가 회전할 수 있도록 지지하는 부시와, 상기 반구들을 축에 고정시키는 고정수단을 구비한 반구형 유체 베어링에 있어서, 상기 반구의 주면에 코팅된 티타늄 막과, 이 티타늄 막의 주면에 코팅된 DLC막과, 이 DLC막에 다수의 그루브를 형성시켰으며, 그 제조방법으로는 반구의 주면에 티타늄을 코팅하는 단계와, 상기 티타늄의 코팅된 반구의 주면에 DLC를 코팅하는 단계와, 상기 DLC가 코팅된 반구의 주면을 다수개의 그루브가 형성되도록 에칭하는 단계를 포함하도록 하였다.
