크랭크샤프트 베어링의 종류, 위치, 캠샤프트 베어링과의 차이점에 대해 알고 싶음
처리 내용
크랭크샤프트의 주요 베어링 종류는 롤러 베어링과 플레인 베어링으로, 크랭크샤프트의 메인 저널에 위치합니다. 크랭크샤프트의 저널은 메인 저널(크랭크샤프트 메인 베어링 위치)과 로드/오프셋 저널(커넥팅로드 베어링 위치) 두 가지 타입이 있습니다. 롤러 베어링은 조립 중에 크랭크샤프트에 프레스됩니다. 이런 방식으로 장착된 베어링을 교체하려면 크랭크 핀/저널을 카운터웨이트에서 프레스 아웃해야 합니다. 플레인 베어링은 반으로 분할되며, 일반적으로 분할 가능한 크랭크케이스나 메인 베어링 캡을 지지하는 타입과 관련이 있습니다. 이는 오프셋/로드 저널의 커넥팅로드에도 해당됩니다. 플레인 베어링은 저널 주위를 감싸고 오일 압력이 가해져, 크랭크 저널이 저널과 플레인 베어링 사이의 오일층 위에서 작동합니다. 이를 유체동압 윤활이라고 합니다. 캠샤프트 엔드 베어링은 다르며...

Brief history:I was thinking about buying myself a fun sports car, there's nothing new in the £50-80k range I would particularly be interested in. Had to feel special, had to be light, "analogue" and not overly-assisted. Had to be manual and i prefer a large capacity NA to forced induction. Ford Mustang maybe, perhaps not quite special enough and a bit porky. Emira - I love Lotus and have had a few but i'm not a fan o
BMW X5
After writing off my BMW 320d halfway through the month, I suddenly found myself in the market for a new car.Once the insurance payout landed, I had just under £5,500 to play with after paying my excess. I spent hours trawling AutoTrader trying to find the right replacement.I'd lined up a BMW X5 that was slightly over budget and was due to view it today... only for it to sell yesterday before I got the chance. Frustrating, but that's just how it goes.I kept looking, but nothing else really grabbed me.Then I spotted a Range Rover Sport on AutoTrader just five miles away. I called the dealership
