  • Publication number: 20200056677
    Abstract: A damping device that includes features for damping bending vibration of a shaft rotating about its axis of rotation and methods for damping bending vibration utilizing the damping device are provided. In one exemplary aspect, the damping device includes a damping disc operatively coupled with a shaft, e.g., of a turbine engine or shaft system. The damping disc is at least partially received within a chamber defined by a housing. The chamber of the housing is configured to receive a damping fluid. When the shaft is rotated about its axis of rotation, the damping disc is movable within the chamber to move the damping fluid such that the damping fluid absorbs bending vibration emitted by the shaft. The damping fluid moved by the damping disc dampens bending vibration emitted by the shaft.

  • Publication number: 20200056680
    Abstract: A multi-speed transmission having drive and output shafts, front-mounted planetary gearsets, rear-mounted planetary gearsets and six shift elements. Selective engagement of shift elements selectively renders a drive shaft speed and speeds generated in the front gearsets for achieving a reverse gear and twelve forward gears via the rear gearsets transmissible as an output speed to the output shaft. Four shift elements are assigned to the front gearsets and two are assigned to the rear gearsets. At least one front gearset is rigidly connected to an element of the rear gearsets, resulting in six different output speeds of the front gearsets being transmissible to the rear gearsets. If normalized to the drive shaft input speed, one output speed is smaller than 0, three output speeds are between 0 and 1, one output speed is equal to 1 and one output speed is greater than 1.

The distal end of the extension tube extends through the end of the main housing and includes an end cap or a connector. The proximal end of the drive shaft connects to a drive axle on a multiple gear assembly. The multiple gear assembly is coupled to a dual motor assembly. Located adjacent to the dual motor assembly is a volume compensation housing that contains a moving piston that divides the housing lubricant holding chamber filled with a lubricating fluid and an air chamber that communicates with outside air. During operation, the lubricating flows into the motor assembly, the gear assembly, into the nut body and to the extension tube.
