  • Patent number: 8454309
    Abstract: A wind turbine comprising an electrical generator that includes a rotor assembly. A wind rotor that includes a wind rotor hub is directly coupled to the rotor assembly via a simplified connection. The wind rotor and generator rotor assembly are rotatably mounted on a central spindle via a bearing assembly. The wind rotor hub includes an opening having a diameter larger than the outside diameter of the central spindle adjacent the bearing assembly so as to allow access to the bearing assembly from a cavity inside the wind rotor hub. The spindle is attached to a turret supported by a tower. Each of the spindle, turret and tower has an interior cavity that permits personnel to traverse therethrough to the cavity of the wind rotor hub. The wind turbine further includes a frictional braking system for slowing, stopping or keeping stopped the rotation of the wind rotor and rotor assembly.

  • Patent number: 6953412
    Abstract: A reversible one-way clutch (90) is positioned in parallel with a friction pack (62, 72) to drive a planetary transmission (10) in low gear and reverse. The clutch (90) has a biasing plate (96) secured to its surface to bias the clutch (90) in a direction so that the transmission (10) operates in either low gear or reverse gear. The biasing plate (96) is hydraulically actuated to bias the clutch (90) between low gear, neutral, and reverse gear.

  • Patent number: 6338403
    Abstract: A ratchet-type one-way clutch mechanism 300, 360. The mechanism has an inner race member 302, 364 with a plurality of notches 312, 372, an outer member 304, 362 with a plurality of pockets 310, 370, a plurality of pawl members 306, 368 positioned in the pockets for engagement with the notches, and spring biasing members 308 for biasing the pawl members toward engagement. The outer member can be a stator member 362 or an outer race member 304. Retainer members 314, 366 retain the pawls axially in the pockets. Bearing surfaces 303, 305, 307, 315 on the inner race member, outer member and retainer member provide bearing support. Large radii R1 on the pawl members and pawl pockets reduce wear and minimize the cost of secondary machining operations. The lower surfaces 344 of the pawl members are curved and the curvature R2 can be larger than the curvature R3 of the inner race member.

  • Patent number: 6332520
    Abstract: The invention is a planar clutch having a plurality of pawls and a related plurality of notches numerically selected so that two more pawls are engaged at substantially the same time, thus sharing and balancing the eccentric forces of engagement between the drive plate and the driven plate. The pawls have a cross-sectional design, wherein each pawl has surfaces for receiving compressive loading forces and is thicker at a middle point between the surfaces for receiving compressing loading forces. A pivot ridge is located at the thickest area of the pawl.
