ROLLER BEARING Russian patent published in 2009 - IPC F16C19/49 F16C19/20 B61F15/12

Abstract RU 2346190 C2

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering, namely to rail and other types of transportation. A roller bearing comprises one or two rows of rollers taking radial load and a ball bearing taking axial load which is mounted so that to provide for its self-adjustment in respect to the roller bearing rotation axis. A bearing with arched race profile is used as the ball bearing. Contact angle in the ball bearing is equal to: where f - coefficient of sliding friction; z - quantity of balls in the ball bearing.

EFFECT: bearing design simplification and increase of its work efficiency.
