摘要： PROBLEM TO BE SOLVED: To provide a roller bearing device capable of efficiently lubricating a roller bearing with a small amount of lubricating oil by suppressing a state that lubricating oil from a nozzle flows out to the oil feed unit side or the outside of the roller bearing without contributing to the lubrication of the roller bearing in the roller bearing device, which is provided with the oil feed unit for directly feeding the lubricating oil in a tank into the roller bearing by a pump via the nozzle opened near a rolling body in an annular space between an inner ring and an outer ring of the roller bearing.
SOLUTION: An annular shield member 3, which partitions at least a space on the outer ring 12 side in a space between the tip opening part of the nozzle 23 and the pump 22, is arranged between the tip opening part of the nozzle 23 and the pump 22. Consequently, it is possible to prevent the lubricating oil from moving toward the pump 21 side through the outer ring 12 side due to centrifugal force and disturbance of an air flow accompanied with the rotation of the roller bearing. It is also possible to increase an amount of the lubricating oil moving to a rolling contact part between the inner/outer rings 11, 12 and the rolling body 13 and to the retainer 14 side.

SOLUTION: This rolling bearing device is provided with the nozzle 22 communicated with the tank 21 storing lubricating oil and opened within the annular space between the inner ring 11 and the outer ring 12 of the rolling bearing to directly supply lubricating oil to inside of the bearing. The rolling bearing device is further provided with a means for restricting outflow of lubricating oil inside the tank 21 via the nozzle 22 (for example, an oil-containing member 25 inside the tank 21), and is constituted so as to supply the lubricating oil inside the tank 21 via the nozzle 22 by negative pressure generated inside the bearing at the time of rotation of the rolling bearing. Due to this structure, the necessity of a pump for supplying lubricating oil and its drive circuit is eliminated.
