  • Patent number: 9534584
    Abstract: A wind turbine system includes turbine blades (16) that turn a low speed shaft (18). A shrink disc coupling (24) radially connects the low speed shaft to a low speed gear box input shaft (22). A brake (26) for the gear box input shaft is operatively connected with the coupling. At least one circuit including a processor controls the brake to keep torsional force on the gear box input shaft below a threshold. The at least one circuit is associated with sensors that can sense conditions away from the gear box input shaft. The at least one circuit can determine when a current condition exists which can cause the threshold to soon be exceeded if preventive braking is not timely applied to the gear box input shaft. The current condition can include a sensed weather condition that is approaching the wind turbine system.

  • Publication number: 20100155991
    Abstract: A bushing can include a shoulder, a ring, and a ground shield. The ring can be arranged circumferentially around a first outside diameter of the bushing, wherein the ring includes a channel. The ground shield can include a semiconductive rubber collar that forms part of an outer surface of the bushing and extends circumferentially under a portion of the ring. The insulative portion can be adjacent to the ring and disposed over a portion of the ground shield. A method of manufacturing the bushing can include placing the ring and the ground shield into a mold, the ground shield including holes therein, and injecting insulative material into the mold to create an insulative layer within a cavity formed by the ring and the ground shield, the holes in the ground shield allowing some of the insulating material to flow therethrough to create the insulative portion adjacent the ring.

  • Publication number: 20100111626
    Abstract: A cushion mechanism in a positive feed drill slows the advancement of a cutter prior to reconnecting with a machining surface during a clearing operation. The cushion mechanism may be inserted in a piston, in front of a shaft, or attached to the outside of the positive feed drill. The cushion mechanism may include a spring washer, a compression spring, or a hydraulic or pneumatic damper. The cushion mechanism provides a safer and more efficient operation for positive peck drilling.
