20100140019 | Lubricating system for gear train - This invention provides a lubricating system for a gear train including: a lubricating oil supply port configured to supply a lubricating oil in a direction vertical to both axes of a pair of gears and toward a mesh point at which the pair of gears are meshed with each other; a shroud configured to cover at least teeth of the pair of gears so as to form a flow passage of the lubricating oil between the pair of gears and the shroud; and a pair of discharge ports respectively configured to discharge the lubricating oil from the flow passage. The pair of discharge ports are respectively positioned at two portions of the shroud respectively opposed to the mesh point across respective axes of the pair of gears. | 06-10-2010 |
20110105270 | PLANETARY GEAR REDUCTION SYSTEM - A planetary gear reduction system has a sun gear, a plurality of planet gears, a ring gear, and a planet carrier. The planet carrier has a first plate supporting one ends of planet shafts supporting the planet gears, a second plate supporting the other ends of the planet shafts, and a cylindrical drum connecting the first and second plates. The first plate has first portions supporting the one ends of the planet shafts; second portions connecting the first plate to the drum, the first and second portions being provided alternately in a circumferential direction; first cutouts each defined between the neighboring first and second portions, the first cutouts each extending radially inwardly from a circumferential edge thereof to a position adjacent a circle passing centers of the planet shafts; and second cutouts each defined radially inward of the second portion and between the neighboring two first portions, the second cutouts each extending radially inwardly from a first region outside the circle and a second region inside the circle. | 05-05-2011 |
20130025405 | GEAR TRAIN LUBRICATING DEVICE - A gear train lubricating device configured to supply lubricating oil OL to a gear included in a gear train is provided. The gear train lubricating device includes: a shroud covering, among components constituting the gear, at least teeth of the gear; and a lubricating oil supply port through which the lubricating oil OL is supplied to a meshing position of the gear. The shroud has an outlet port formed therein, through which the supplied lubricating oil OL is discharged. The outlet port is formed in a portion of the shroud that is positioned radially outward from the gear, such that the outlet port is disposed at an angular position that is 90°±15° forward from the meshing position in a rotation direction R | 01-31-2013 |
