  • TAPERED ROLLER BEARING FOR AUTOMOBILE TRANSMISSION
    Publication number: 20070269158
    Abstract: The present invention provides a tapered roller bearing for an automobile transmission that is capable of preventing early surface originating flaking attributable to lack of oil film even when the oil film parameter ? is in the range of 0.8 or less. Further, in a tapered roller bearing for an automobile transmission to be used with an oil film parameter ? being equal to or more than 0.5, the roughness of the raceway surfaces of both the inner and outer rings is rendered less than twice the roughness of the rolling contact surface of a roller.
