Each tapered roller includes a flange having an angled and convex flange contact surface that contacts the lower rail. The lower rail and/or the upper rail can include an angled surface configured for contact with the flange contact surface. The geometry of the rollers and the lower rail are configured to reduce the stresses applied to the rollers and lower rail due to contact between the flange contact surface and the angled surface. | 11-27-2014 |

| 20080292235 | SLIDING MATERIAL, METHOD OF MANUFACTURING SAME AND BEARING ASSEMBLY - A sliding material sliding material includes: a sliding plane member; a base member made of a material different from that of the sliding plane member; an intermediate member provided between the sliding plane member and the base member and formed with a plurality of spaces; and a joining member for bonding the intermediate member to the base member, in which a portion of the space formed to the intermediate member is impregnated with a portion of the sliding plane member so that the sliding plane member is bonded to the intermediate member, and a residual portion of the space of the intermediate member is impregnated with a portion of the joining member so that the base member is bonded to the intermediate member with the joining member therebetween. | 11-27-2008 |
| 20090116780 | Bearing Systems - Bearing arrangements are described which enable rotation about a vertical axis with a very extended diameter bearing, for example 20 meters diameter. A usually stationary base supports a rotating member, e.g. on a fluid cushion. Separately, a ring of radially adjustable arcuate surface support pads on an outer member acts against a cylindrical surface of an inner member. The adjustability of the radially movable support pads enables them to increase their thrust at parts of the circumferences of the bearing relative to others. This enables considerably smoother running to be achieved, both to compensate for the difficulties of producing complete circularity with a bearing diameter of substantial size, and for varying direction lateral loadings, e.g. as experienced by a vertical axis wind-driven turbine. | 05-07-2009 |
| 20110150383 | GEAR BOX FOR WIND TURBINE GENERATOR AND SUPPORTING STRUCTURE FOR ROTATION SHAFT - 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. | 06-23-2011 |
