The duct includes a plurality of flat panel members which together define the outer extremity of the path. | 2014-04-10 |
20140099199 | Duplex Bearing Lubrication - A bearing system has first and second bearings each having an inner race. The inner races are mounted to a shaft. The first bearing inner race has a plurality of first ports. The second bearing inner race has a plurality of second ports. The shaft is insertable into the inner races in a plurality of orientations and has a plurality of outer diameter (OD) channels positioned to cooperate with at least the first bearing inner race to communicate with at least some of the first ports and at least some of the second ports. Regardless of said installed orientation, at least one of the second ports are in communication with at least one said inlet port along a flowpath bypassing all the first ports. | 2014-04-10 |
20140099200 | FAN STRUCTURE - A fan structure includes a rotation module, a fixing shaft and an impeller, the rotation module comprises a coupling base, a bearing and a sealing member. The bearing comprises an axial hole, an outer ring wall and a through hole, a slot is recessed from the outer ring wall, the through hole communicates with the slot and the axial hole, and the slot is sealed by the sealing member to form an oil storage space. The fixing shaft penetrates the axial hole, and the through hole communicates with the axial hole and the oil storage space. When the rotation module rotates, lubricants in the oil storage space can flow from the through hole to the axial hole for lubricating the fixing shaft and the axial hole. When the rotation module stops, lubricants in the axial hole reflow to the oil storage space via the through hole to avoid loss. | 2014-04-10 |
