An apparatus for amplifying rotating force of a wind power generator includes a blade rotated by wind power, a central rotating shaft rotated by the rotation of the blade, upper and lower horizontal rotating units spread upwards or downwards when the blade rotates, upper and lower fastening plates, a vertical rotating unit continuously rotating the upper horizontal rotating unit and doubling the rotating speed of the upper horizontal rotating unit by repulsive force of a magnetic member, a horizontal rotating shaft rotating the vertical rotating unit as the blade rotates, a shaft conversion unit rotating the horizontal rotating shaft by the rotation of the central rotating shaft, a horizontal-rotating-shaft support supporting the vertical rotating unit and the horizontal rotating shaft, a frame unit stably holding the apparatus and protecting the apparatus from external force, and a bearing.

A vertical axis wind turbine system having a vertical mast with one or more turbine units supported thereon. The turbine units are of modular construction for assembly around the foot of the mast; are vertically moveable along the height of the mast by a winch system; and are selectively interlocking with the mast to fix the turbine units in parked positions. The turbine system and each turbine unit includes a network of portals and interior rooms for the passage of personnel through the system, including each turbine unit. The electrical generators, and other sub-components, in the turbine units are of modular construction that permits the selective removal and replacement of component segments, including the transport of component segments through the portals and interior rooms of the turbine system while the turbine units remain supported on the mast. The electrical generators are also selectively convertible between AC generators and DC generators.

The present disclosure is directed to a lubrication system for a gearbox that is part of a drivetrain assembly, e.g. of a wind turbine. The lubrication system includes a ring assembly having a first ring and a detached, second ring. The first and second rings are configured to fit within a gap located between a planetary gear system and a gearbox housing of the gearbox, e.g. due to operational and/or system tolerances. When installed, the first and second rings of the ring assembly are arranged together so as to form at least one opening therebetween, thereby being configured to direct a lubricant from the gearbox housing to the planetary gear system.

A wind turbine having one or more magnets for reducing friction between the turbine support and a turbine rotor. The reduction of friction between the turbine rotor and the turbine support allows for an increase in energy production and scale of the wind turbines. The magnet configuration employs a ring of cylindrically-shaped magnets at the bottom and opposed by a corresponding number of generally rectangular-shaped magnets. Bearing magnets are also employed for axial stabilization.

A wind power generator is provided with a drive unit, a clutch hydraulic source, and a clutch control portion. The drive unit has a hydraulic clutch mechanism configured to perform switching between transmission and non-transmission of rotary power from an output shaft to a pinion. The clutch hydraulic source supplies a hydraulic pressure to the clutch mechanism. The clutch control portion controls a hydraulic pressure supplied from the clutch hydraulic source to the clutch mechanism.

A disk armature generator for generating electrical energy from rotational energy of a wind power installation and comprising at least two stator components mutually offset axially along a generally horizontal rotation axis of the disk armature, and comprising, mounted therebetween so as to rotate about the rotation axis, at least one ring- or disk-shaped rotor component of the disk armature, and comprising an input-side connection for a gearbox wherein the sun gear thereof, which extends coaxially with the rotation axis of the disk armature, is coupled to at least one ring- or disk-shaped rotor component of the disk armature, wherein a rolling bearing associated with a ring- or disk-shaped rotor component of the disk armature is configured as a selected one of an angular contact ball bearing and angular contact ball bearings, having a contact angle of between 40° and 50° relative to the rotation axis, comprising a double-row angular contact ball bearing in an O arrangement.

The present disclosure is directed to a gearbox assembly for a wind turbine. The gearbox assembly has a maximal installed width and a maximal transport width. The maximal installed width is greater than the maximal transport width. The gearbox assembly includes at least one torque arm coupled to opposing sides of the gearbox housing. Each of the torque arms includes a proximal end and a distal end. The proximal ends are removably coupled to the exterior surface of the gearbox such that the distance between the distal ends define the maximal installed width. The torque arms are coupled to at least one support element and to a bedplate of the wind turbine.

The invention relates to a wind turbine gearbox (1) having at least one gearwheel (2) which is mounted on an axle (5), wherein a bearing point with a plain bearing (4) is arranged between the gearwheel (2) and the axle (5), and wherein, in the axle (5), there is formed a recess for the supply of a lubricant to the plain bearing (4). In the region of a contact surface of the plain bearing (4), a groove (18) is formed in the gearwheel (2) or an intermediate space (7) is formed between the plain bearings (4), which groove or intermediate space is connected via at least one connecting line (16) to the surrounding atmosphere.

Tools, systems, and methods for use in conjunction with maintenance, assembly, rebuilding, or other procedures which involve displacing components of an assembly are disclosed. These tools, systems, and methods may be used in conjunction with a crane or other lifting device and may be configured to assemble, disassemble, or otherwise maintain components of an uptower gearbox.

A vehicle propulsion system comprises at least two motors. Combustion occurs upstream of a first motor, and a second motor is downstream of said first motor. The first motor is a turbine that drives a primary propulsion element to effect propulsion and a compressor to effect compression. The second motor is an expansion device whose incoming gases arrive from said first motor. The first motor and the second motor intercommunicate energy via electrical, electromagnetic, and/or mechanical means. Pressurized gases that result from said compression, combustion, or both are rendered or wastegated for auxiliary usage such as aerial thrust, vertical takeoff and/or vertical landing, near-vertical takeoff and/or near-vertical landing, pneumatic storage for hybrid drive, pneumatic lift and/or drive for towing and/or raising another vehicle, aerial vehicle steering, aerial vehicle pitch stabilization or manipulation, aerial vehicle roll stabilization or manipulation, and/or aerial vehicle yaw stabilization or manipulation.
