A Study on the Rolling Bearing Failure Mode of Automotive Transmission(I)

자동차 변속기용 구름베어링의 파손현상 고찰(I)

This paper shows the failure(wear) phenomena of automotive transmission bearings and investigate their characteristics. It was found that the wear mechanism was mainly abrasive wear by the presence of particles in the gear box and the balls was weared more severely than the other tribological contacting parts. The wear of balls alter the bearing contact angle and load ratings, and finally it cause the bearing failure. With close examination of the failed bearing, various countermeasures could be suggested.
