  • Patent number: 11713747
    Abstract: A method of operating a wind turbine. The wind turbine is operated over an operating period in accordance with a control strategy. A sensor signal is received over the operating period from a sensor measuring an operational parameter of the turbine. A model is used to obtain a modelled fatigue value based on the sensor signal. The modelled fatigue value provides an estimate of fatigue loading applied to a component of the turbine over the operating period. The control strategy is modified based on the modelled fatigue value.

  • Patent number: 11713788
    Abstract: Methods and apparatuses can be used to adjust the torque transfer capacity and improve the overall performance and longevity of a clutch assembly. Through the use of various improved clutch components disclosed herein, it is possible to: (1) increase clutch apply forces through an increase in the fluid pressure apply surface area, or piston reaction area, of a clutch piston, thereby increasing frictional forces generated within a clutch pack for transferring input torque from a drive shaft to a driven shaft; (2) improve clutch plate contact conditions through a more rigid clutch pressure plate configuration, thereby reducing clutch pack/plate distortion and supporting structure deformation and/or wear that can otherwise lead to excessive heat generation and overall clutch performance degradation and/or failure; and/or (3) improve the clutch assembly's ability to dissipate and/or tolerate heat generated through clutch plate friction by means of an improved clutch pack configuration.

  • Patent number: 11713789
    Abstract: A clutch assembly is disclosed herein that generally has at least three operating conditions: an open condition, a transition condition, and a locked condition. The operating conditions are achieved based on displacement of a dog clutch ring relative to a pocket ring and a cam ring. In the open condition, rockers of a ratcheting assembly are completely disengaged from ramps on a cam ring. In the transition condition, the rockers engage with the ramps on the cam ring to allow a ratcheting motion in one rotational direction and a locked state in the other rotational direction. In the locked condition, splines on the dog clutch ring engage with splines on the cam ring to provide a rotationally fixed connection in both rotational directions.

  • Patent number: 11713790
    Abstract: A torque limiting assembly is disclosed comprising: an input shaft; an output shaft; and spring having a first end coupled to the input shaft and a second end coupled with the output shaft. In a low torque mode, when the input shaft is rotated the spring is compressed by a low amount and transmits a force to drive rotation of the output shaft, whereas in a high torque mode the spring is compressed by a high amount such that the input shaft rotates relative to the output shaft. This relative rotation moves or urges an engagement member so as to either: disconnect the input shaft from the output shaft; or engage a housing to prevent or inhibit rotation of the input shaft relative to the housing.

    Abstract: A shock absorbing device includes a control unit and a transmission unit. The control unit includes a first shaft and a second shaft which freely and rotatably extends through the first shaft. The first end of first shaft and the first end of the second shaft protrude beyond the shock absorbing device. The transmission unit includes a first bevel gear and a second bevel gear. The second shaft freely and rotatably extends through the first bevel gear. When the first shaft is rotated to drives the first bevel gear, the first bevel gear drives the second bevel gear to adjust the recovery damping of the shock absorbing device. When the second shaft is rotated, the compression damping of the shock absorbing device is adjusted. The cooperation of the first and second bevel gears makes the operation of the shock absorbing device be smooth and stable.
