A device includes a cylinder sleeve (3, 13), which is at least indirectly arranged at a housing (7) and at least three radially outward extending journals (5). Each journal (5) comes to rest, at least on one side, against a roller element (6a, 6b) accommodated at the housing (7) in order to support the cylinder sleeve (3, 13) on the housing (7) in at least one tangential direction. The device can be designed, in particular, as a planetary transmission or as an electric machine.

A laundry treatment apparatus includes an outer tub to receive wash water, a driving motor having a stator fixed to the outer tub, and a rotor rotated relative to the stator, a washing shaft rotated together with the rotor, and a rotatable spin-drying shaft spaced apart from the rotor. The laundry treatment apparatus also includes an inner tub disposed in the outer tub, a pulsator provided in the inner tub at a lower portion thereof, and a clutch assembly. The inner tub is rotated together with the spin-drying shaft and the pulsator is rotated by the washing shaft. The clutch assembly selects one of a plurality of modes including i) at least one restriction mode of restricting the spin-drying shaft to the rotor or the outer tub and ii) a free mode of not restricting the spin-drying shaft to the rotor and the outer tub.

A bearing is mounted to a static structure outwardly of the shaft, and supporting the shaft. A bearing compartment is defined by face seal arrangements on each of two axial sides of a bearing. Each face seal arrangement includes a seal seat rotating with the shaft and a non-rotating sealing ring. The seal housing is exposed to high pressure air outward of the bearing compartment. A coil spring biases the seal housing towards the seal seat, such that the sealing face is biased into contact with the seal seat by a bias force including a net fluid force acting on the seal housing and the coil spring. The sealing face is defined by a contact portion contacting the seal seat and a feed portion recessed from the seal seat. The feed portion includes a plurality of circumferentially spaced feed slots fluidly connected to at least one annular groove.

The embodiments disclose a method including transferring kinetic energy from a kinetic energy source to a flywheel storage device system, transferring all or a portion of the kinetic energy stored to a continually variable transmission planetary gear system, integrating a multiple axis mechanism kinetic energy transference device to the continually variable transmission planetary gear system, integrating multiple speed governors in the multiple axis mechanism kinetic energy transference device, coupling a computer controlled module to each of the speed governors, processing operational data with the computer controlled modules to determine a measured most efficient use of the kinetic energy for each operation, transmitting the operation measured most efficient use amount of the kinetic energy from the computer controlled module to the corresponding speed governor, transferring the amount of the kinetic energy through gears and output shafts/drive shafts to serve operations and storing surplus kinetic energy not needed for operations in the flywheel storage system.
