| 摘要 |
The present invention pertains to a bearing device (10) comprising a bearing (11) and a lubricating oil supplying unit (20) connected to the bearing (11), wherein the lubricating oil supplying unit (20) comprises a lubricating oil tank (30) to hold lubricating oil to be supplied into the bearing (11), a supplying unit to supply the lubricating oil from the holding unit into the bearing (11), and a power generating unit (25) to generate power. Moreover, in the bearing device (10), the supplying unit is operated by the power generated by the power generating unit (26) and comprises a nozzle (32a) for supplying the lubricating oil into the bearing (11). In addition, in the bearing device (10), the distal end of the nozzle (32a) in the axial direction of the bearing (11) is positioned more toward the center of a retainer (16) than an end face (16a) of the retainer (16), and the ratio of the distance (A) from the end face (16a) of the retainer (16) to the distal end of the nozzle (32a) with respect to the width (W) of the retainer (16) exceeds 0% but is no more than 20%. |
