COMPENSATION FOR INSUFFICIENT SUPPLY OF LUBRICANT TO INTER SHAFT BEARING

摘要

PPROBLEM TO BE SOLVED: To provide a rolling bearing capable of getting rid of fault caused by insufficient supply of lubricant. PSOLUTION: The lubricating characteristic of the inter shaft bearing 10, in particular, a bearing having a reverse rotation bush is improved by the presence of an obstacle 42 in an outer bush 12, and the quantity of oil existing in an outer rolling raceway track 20 can be controlled by the obstacle 42. For details, the drying of the rolling raceway track 20 caused by repeated running of a runner 14 can be compensated by forming forced axial circulation. PCOPYRIGHT: (C)2006,JPO&NCIPI
