Abstract: A geared power train (100) for use in a wind turbine application to maximize a step-up ratio within a radial space that is defined by the planetary gearing system ring gear size. The geared power train (100) is configured as a split-compound planetary gearing system with a closed-carrier flex-pin planetary system in a high-torque stage (Stage 1) for receiving driving torque via an input shaft (IN) from a wind turbine, and an open-carrier flex-pin planetary system in a low-torque stage (Stage 2) coupled to the high-torque stage (Stage 1) for delivering the driving torque to an electrical generator via an output shaft (OUT).

Abstract: A transmission for a wind turbine includes a housing ( 20 ) in which two shafts ( 26, 28 ) rotate, each being supported on a locating bearing ( 50, 60 ) which transmits thrust loads to the housing as well as radial loads and on a nonlocating bearing ( 48, 58 ) which transmits only radial loads to the housing. The shafts carry helical gears ( 52, 52, 62 ) which induce thrust loads in the shafts when the shafts transmit torque. The locating bearings are unitized single row tapered roller bearings which are oriented to transmit thrust loads in the primary direction through their raceways ( 132, 138 ) and in the secondary direction through ribs ( 134, 144 ) at the ends of their rollers ( 146 ). The nonlocating bearings take the form of a single row cylindrical roller bearings which accommodate differential thermal expansion and contraction between the shafts and housing.

Abstract: An epicyclic gear system (A) includes helical sun and ring gears (2, 4) and helical planet pinions (6) located between and engaged with the sun and ring gears. The gear system also includes a carrier (8) having an end wall (12) and flexpins (20) cantilevered from the end wall and extended into the planet pinions. Each flexpin at its end remote from the end wall carries a sleeve (22) that extends back over the flexpin where it is spaced from the flexpin. The planet pinion for the flexpin rotates around the sleeve on a bearing (24). The arrangement is such that the flexpin will flex adjacent to the carrier end wall circumferentially along the pitch circle of the carrier in one direction and circumferentially in the opposite direction adjacent to attachment of the sleeve. But the helical gear imparts a couple to the planet pinion that seeks to tilt the sleeve radially toward or away from the main axis of the system. A deflection inhibitor (I) lies between each flexpin and the sleeve surrounding it to prevent the radial deflection.

Abstract: An epicyclic gear system has a sun gear, a ring gear, and planet gears between the sun and ring gears. In addition, it has a carrier including a carrier flange offset axially from the planet gears and carrier pins that project from the flange into the planet gears, each with a shank anchored to the flange, a head remote from the flange, and a groove between the shank and head. Between the planet gears and the carrier pins are bearings, each including an inner race and rollers between the inner race and planet gear. Whereas the carrier pins are cantilevered from the carrier flange, the inner races are cantilevered from the heads of the carrier pins. The grooves in the pins enhance pin deflection, so that the axes about which the planet gears rotate remain parallel to the central axis of the system.

Abstract: Un montage de roue (A, B, C, D) comprend une roue (W), un moyeu (4), une broche (2) et une paire de roulements à rouleaux coniques (6 et 8) indirectement montés entre le moyeu (4) et la broche (2). Un support (10) de joint d'étanchéité et une plaque terminale de couverture (122) ferment l'extrémité du moyeu (4) et forment une extrémité d'une chambre hermétiquement fermée (128) à l'extrémité de la broche (2). Un joint d'étanchéité (130, 136) porté par le support (100) s'appuie contre une surface d'étanchéité (94) effectivement portée par la broche (2) et définit ainsi l'autre extrémité de la chambre (128). Un premier passage (26, 60, 64, 70, 96) met une source d'air comprimé (28) éloignée des roulements (6, 8) en communication avec la chambre (128) le long de la broche (2). Un deuxième passage (44, 110, 118) met en communication l'intérieur du pneu (T) avec la chambre (128) à travers le moyeu (4) et la bague terminale (100). Le montage (A, B, C, D) permet ainsi de transférer de l'air du ou vers le pneu (T) pendant que la roue (W) est en rotation.
