ABSTRACT:
A multiblade, wind-driven, variable pitch propeller is supported on a tower for rotation by wind forces and is connected through gears to drive an electrical generator or the like to produce electrical energy. The gears include a ring and pinion arranged in a gear case so that wind forces acting on the propeller and torque forces produced in the gears are balanced, thus avoiding swinging movement of the propeller about the tower axis due to unbalanced forces and thereby keeping the propeller axis pointed into the wind. The pinion gear is engaged with the ring gear at a location spaced near the top of the ring gear and a pinion shaft sleeve is disposed around the pinion shaft and sealed to a bottom portion of the gear case to effect a gear lubricant seal therewith, thus eliminating the requirement for an oil seal between the pinion shaft and gear case, with concomitant elimination of the oil seal drag, and also eliminating friction drag of the gear lubricant itself on the pinion shaft. Further, the danger of damage to the components in the event of loss of gear lubricant from the gear case is avoided by provision of the pinion shaft sleeve.
