Abstract
Description
Claims (3)
- 중앙에 코어가 설치된 형틀 내부에 모재를 삽입하고 상기 코어와 모재 사이에 금속혼합분말을 공급하되, 상, 하부펀치로 상기 금속혼합분말을 가압 성형한 후 소결시켜 모재와 결합시키고, 소결 결합된 모재와 금속혼합분말층의 상, 하면과 내, 외측면을 재가압하며, 상기 재가압된 모재와 금속혼합분말층을 다시 소결 가공하여 미끄럼베어링을 제조하는 방법에 있어서,상기 모재(200)와 금속혼합분말층(300)을 재가압하는 단계(S600)에서는 샤프트(510), 메인롤러(520), 에지롤러(530)로 구성된 링롤링유닛(500)을 통해 동시에 가압하는 것을 특징으로 하는 미끄럼베어링 제조방법.
- 제 1항에 있어서, 상기 재가압단계(S600)에서 링롤링유닛(500)의 샤프트(510) 외주면에는 다수의 돌출턱(511)을 형성하여 금속혼합분말층(300) 내측에 다수의 오일홈(310)이 형성되게 한 것을 특징으로 하는 미끄럼베어링 제조방법.
- 제 1항에 있어서, 상기 형틀(400)에 모재(200)를 삽입하기 이전에 모재(200)의 내측면을 요철형태로 가공하는 모재내경 가공단계(S100')를 더 포함하는 것을 특징으로 하는 미끄럼베어링 제조방법.
