摘要 |
Provided is a cooling structure for a bearing device. The bearing device includes a rolling bearing having a stationary raceway ring and a rotating raceway ring, a stationary spacer adjacent to the stationary raceway ring and a rotating spacer adjacent to the rotating raceway ring. The stationary raceway ring and the stationary spacer are provided in a stationary member, and the rotating raceway ring and the rotating spacer are provided in a rotating member. The cooling structure includes: an annular recessed portion provided on a circumferential surface, of the stationary spacer, that confronts an opposite spacer; and a nozzle hole configured to inject a compressed air from an outlet open to a bottom surface of the recessed portion toward a circumferential surface of the rotating spacer that confronts an opposite spacer. The nozzle hole is inclined forwardly in a rotation direction of the rotating spacer. |
