  • each key includes a fin that protrudes from the conical frustum.
  • the torque multiplication device also comprises a first balancing flywheel disposed on one side of the splines, and a second balancing flywheel disposed opposite the first balancing flywheel with respect to the splines.

  • FIG. 4 is an illustration of a spline that can be used with the torque multiplication device of FIG. 2 and/or FIG. 3, where the spline is in a first position, according to aspects of the present disclosure
  • FIG. 14 is an illustration of a drive shaft with lubrication channels, according to aspects of the present disclosure.
  • FIG. 19 is block diagram of a system for power generation using a torque multiplication device, according to aspects of the present disclosure.
  • the oblique orbital member 104 can have other shapes including shapes that bulge, protrude or otherwise extend outward between a center of the oblique orbital member 104 and the peripheral edge 110.
  • the oblique orbital member 104 can be constructed from carbon fiber, a carbon-composite, steel, other alloys, a metal such as titanium, one or more hybrid materials, a combination thereof, etc.
  • the tilt plate 112 may include guides 122a, 122b that keep the oblique orbital member 104 from changing its non-perpendicular angle relative to the frame 102, thus maintaining the oblique orbital member's 104 oblique angle relative to the drive shaft 106 while the oblique orbital member 104 rotates.
  • the peripheral edge 110 of the oblique orbital member 104 fits into the guides 122a, 122b so as to create a contactless guide bearing when the drive shaft 106 rotates axially.
  • any specific point on the peripheral edge 110 of the oblique orbital member 104 travels in a helical path relative to the drive shaft 106.
  • dense masses e.g., made from the same material as the oblique orbital member 104 or different material than the oblique orbital member 104 are embedded or affixed near the peripheral edge 110 of the oblique orbital member 104.
  • the oblique orbital member 104 is a flywheel, while in other embodiments, the oblique orbital member 104 is a disk. In various alternate embodiments, the oblique orbital member 104 is a spoked wheel.

  • the coupling ring 926 can rotate around a pitch axis of the drive shaft 906. This is important to allow the oblique orbital member 904 to be placed at any desired angle. Further, the oblique orbital member 904 may also rotate around a yaw axis of the drive shaft 906. This is important to allow for a slight yaw rotation in the oblique orbital member 904 as the guides (122, FIG. 1) keep the oblique orbital member 926 at a constant angle relative to the frame.
  • the coupler 1026 interacts with the magnetic fields created by the magnetic arcs 1060a-c, 1062a-c to create the eddy currents that cause the oblique orbital member 1004 to rotate as well.
  • the drive shaft 1006 interacts with the oblique orbital member 1004.
  • Lubricant within the reservoir 680 provides lubrication between an interface 682a-c between the key 632 and the base 630, which creates a hydrostatic bearing at the interface between the key 632 and the base 630.
  • the lubricant may be supplied to the drive-shaft lubricant channel 676 via a pump (e.g., fluid pump, air compressor, etc.) and a lubricant channel of the frame (e.g., a hose from the pump to the drive-shaft lubricant channel 676, a channel cut into the frame, etc.).
  • a pump e.g., fluid pump, air compressor, etc.

  • the two fluid sub-channels 1551, 1553 align with the sub-channels (1447a and or 1447b and 1447d, FIG. 14) of the drive shaft.
  • the lubricating fluid is pumped into the fluid channels (1441a, 1441b FIG. 14) of the drive shaft, some fluid eventually reaches the interface fluid sub-channel 1551 and the ring fluid subchannel 1553 of the shaft-ring pin 1556.
  • fluid from the pump creates a hydrostatic bearing, hydrodynamic bearing, air bearing, bonded bearing, or combinations thereof wherever two components (coupling ring, shaft-ring pin, orbital-ring pin, drive shaft, oblique orbital member, collar, etc.) interface.
  • Hoses, plumbing, piping, or combinations thereof direct fluid from the pump to the guides (and shaft) to form a hydrostatic bearing, hydrodynamic bearing, air bearing, bonded bearing, or combinations thereof between the guides and the oblique orbital member.
  • a torque multiplication device may incorporate the lubricant delivery systems of FIGS. 6 and 12-16, a combination thereof, etc.
  • the guide 1722 includes side bearings 1719 that include side bearing channels 1721 also use air bearings between an interface between the oblique orbital member 1704 and the oblique orbital member guide 1722.

  • there is only one side bearing 1719 on the guide 1722 there is only one side bearing 1719 on the guide 1722, however, there may be more than one (e.g., side bearing 1719 on each side of the guide 1722).

Abstract

La présente invention concerne un dispositif de démultiplication de couple comprenant un cadre qui supporte un arbre d'entraînement avec un axe de rotation axiale à l'intérieur du cadre et un élément orbital oblique comprenant un bord périphérique. Un coupleur couple l'élément orbital oblique de manière concentrique à l'arbre d'entraînement pour tourner avec celui-ci. Ainsi, l'élément orbital oblique se couple à l'arbre d'entraînement selon un angle oblique de sorte que l'élément orbital oblique se couple à l'arbre d'entraînement de manière concentrique mais non coaxiale. De plus, un guide est couplé au cadre et comprend un canal pour s'adapter au bord périphérique de l'élément orbital oblique de façon à créer un palier de guidage sans contact de telle sorte que, lorsque l'arbre d'entraînement tourne axialement, un point de l'élément orbital oblique se déplace selon un trajet hélicoïdal par rapport à l'arbre d'entraînement. Le coupleur peut être un coupleur cannelé, un anneau de couplage ou un coupleur magnétique.
