A Study on the Rolling Bearing Failure Mode of Automotive Transaxle(II) -Tapered Roller Bearing for Differential Unit

자동차 변속기용 구름베어링의 파손현상 고찰(II) - 차동장치용 테이퍼 로울러 베어링

This paper shows the failure(wear) phenomena of differential bearings in the transaxle of passenger cars and investigate their characteristics. It was found that the wear mechanism was mild abrasive wear caused by the presence of particles in the gear box. The sides of the outer raceway was more neared than center of it, so it is showed as if the crowning of outer raceway are increased. With close examination of the failed bearing, various countermeasures could be suggested.
