A pump system may include a pump, a driveshaft, driving equipment, and a vibration dampening assembly configured to reduce pump-imposed high frequency/low amplitude and low frequency/high amplitude torsional vibrations. The pump may have an input shaft connected to the driveshaft. The driving equipment may include an output shaft having an output flange connected to the driveshaft. The driving equipment may be configured to rotate the driveshaft to rotate the input shaft of the pump therewith. The vibration dampening assembly may include one or more flywheels operably connected to the input shaft and configured to rotate therewith.

An electromechanical flywheel machine includes a flywheel mass enclosed in an evacuable housing.

An electromechanical flywheel machine includes a flywheel mass enclosed in an evacuable housing.

A flywheel system comprises a flywheel rotor comprising a rotor disc and a rotor shaft and has a longitudinal axis extending centrally through the rotor disc and the rotor shaft. The system further comprises a journal assembly configured to facilitate rotation of the flywheel rotor. The journal assembly comprises a sleeve having an aperture extending therethrough from a first end to a second, opposite end, a rod at least partially disposed within the aperture of the sleeve, and a nut coupled to a portion of the rod. The rod has a length greater than the sleeve such that a portion of the rod extends axially beyond the first end of the sleeve. A method of forming the flywheel comprises coupling the rod to the rotor shaft and pulling the second end of the rod to tension the rod. The nut maintains the tension in the rod when coupled thereto.

The present disclosure provides flywheel systems for generating and/or storing energy, and methods of using same.

A gyroscopic roll stabilizer comprises a gimbal having a support frame and enclosure configured to maintain a below-ambient pressure, a flywheel assembly including a flywheel and flywheel shaft, one or more bearings for rotatably mounting the flywheel inside the enclosure, a motor for rotating the flywheel, and bearing cooling system for cooling the bearings supporting the flywheel. The bearing cooling system enables heat generated by the bearings to be transferred through the flywheel shaft to a heat sink disposed within a cavity in the end of the flywheel shaft, or to a liquid coolant circulating within the cavity.

A flywheel assembly for a prime mover includes a flywheel and a ring gear. The flywheel has a first plurality of apertures for receiving a first plurality of fasteners for fixing the flywheel to a prime mover, a first cylindrical ring portion including a first outer diameter, a second cylindrical ring portion at a first distal end of the first cylindrical ring portion and including a second outer diameter, larger than the first outer diameter, and a third cylindrical ring portion at a second distal end of the first cylindrical ring portion, opposite the first distal end, and including a third outer diameter, larger than the second outer diameter. The flywheel also has a first wall connecting the first distal end of the first cylindrical ring and a third distal end of the second cylindrical ring portion. The ring gear is engaged with the first cylindrical ring portion.

A flywheel assembly 10 comprising: at least one flywheel mass support 14, the or each said support having a shaft 19 that extends along a rotational axis 18 about which the support 14 can rotate in use, the or each said support 14 comprising a plurality of openings 24 that are each offset from said rotational axis 18, a flywheel mass 12 comprising a plurality of openings 16 that are each arranged to align with a corresponding opening in said support; and means 23 for coupling said flywheel mass 12 to the or each said support 14 so that the mass 12 can rotate with the or each support 14 in use, said coupling means 23 being configured to extend through the aligned openings in the or each support 14 and said flywheel mass 12; wherein said flywheel mass 12 comprises a plurality of generally planar flywheel mass elements sandwiched together to form a stack of elements, each said element including a plurality of openings 16 that align with the openings 24 in the or each said support 14 and with openings in neighbouring elements in said stack, said flywheel elements being coupled together and aligned with one another to form said flywheel mass solely by means of the coupling means 23 that extends through the aligned openings in said elements and the or each said support 14.
