摘要： It is an object to provide a gear box for a wind turbine generator and a rotation-shaft supporting structure which are capable of suppressing the occurrence of slips in a bearing with lower costs. A gear box for a wind turbine generator which increases a speed of rotation of a wind turbine blade includes a gear to which the rotation of the wind turbine is transmitted, and the gear includes a rotation shaft which is rotatably supported by a first bearing and a second bearing. The first bearing includes a pre-load applying member adapted to partially press the first bearing from outside for increasing contact pressures between an outer ring supported by a casing of the gear box, an inner ring mounted on the rotation shaft, and rollers provided between the outer ring and the inner ring.

摘要： A pump for carrying supercritical CO2 fluid or liquid CO2 capable of securing reliability by optimizing a bearing part. An angular ball bearing (8) comprises an inner ring (8a), an outer ring (8b), balls (8c) held therebetween, and a cage (8d) holding the balls (8c). Both the balls and the inner and outer rings are formed of a ceramic to form a totally ceramic bearing. Also, the cage (8d) is guided by the outer ring or the inner ring. Specifically, for example, when the cage is guided by the inner ring, the inner peripheral surface (8db) of the cage (8d) opposed to the outermost peripheral surface (8ab) of the inner ring (8a) is guided by the outermost peripheral surface (8ab) of the inner ring (8a).
