Definitions

  • the invention relates to a gearbox, and more particularly, to a gearbox comprising a compound gear train that increases or decreases speed and/or torque from on input source to an output.
  • Gearboxes are a component of many mechanical, electrical and hydraulic devices. Fundamentally, gearboxes typically comprise an input shaft, a gear or series of gears combined in such a manner to increase or decrease torque/speed, and an output shaft. For example, through the use of a gearbox, torque increases in direct proportion to the reduction of the rotations per minute of the output.
  • gearboxes are purposed to not just increase or decrease torque/speed, but to place the torque/speed at the ideal level for utilization by the end device.
  • gearboxes which comprise different types of gears, such as e.g. spur gears, worm gears, bevel gears, and planetary gears, to name a few.
  • the type used for a given application often depends on the desired use of the gearbox, as well as other factors such as cost, size, etc.
  • Gearboxes facilitate many processes, and are therefore useful throughout industry. Some examples of uses of gearboxes include running conveyor belts, windmills, turbines, medical machines, food processors, printing devices, computers, automotive engines and construction-related machinery. The inherent usefulness of gearboxes implores further design in an attempt to increase durability, efficiency and cost-effectiveness.
  • a gearbox comprising a wheel oriented vertically; a first set of teeth on a first face of the wheel defining a first gear; a second set of teeth on a second face of the wheel defining a second gear; an input gear operably engaged with the first set of teeth on the first gear; an output gear operably engaged with the second set of teeth on the second gear; wherein the input gear engages the first gear at about 0° to 90° above the horizontal.
  • Figure 1 is a right side perspective view of an embodiment of the gearbox according to the present invention
  • Figure 2 is a left side perspective view of an embodiment of the gearbox according to the present invention.
  • Figure 3 is a top view of an embodiment of the gearbox according to the present invention.
  • Figures 4 is a front view of an embodiment of the gearbox according to the present invention.
  • Figure 5 is a left side view of an embodiment of the gear according to the present invention.
  • the Figures illustrate an exemplary mechanical gearbox 10 according to an embodiment of the present invention.
  • the mechanical gearbox 10 comprises a wheel or disk 12 that effectively serves as a gear.
  • the wheel 12 may be of any size, and is largely dependent upon how and where the gearbox 10 will be used. For larger embodiments, it is preferred that the wheel 12 be at least approximately 38.5 inches in outer diameter.
  • the wheel 12 is oriented in an upright and vertical position as can be seen throughout the Figures.
  • the wheel 12 is supported by an axle 20 that communicates with the wheel 12 substantially at its center.
  • the axle 20 is then preferably supported by vertical supports (not shown) that extend down to the ground.
  • the axle 20 extends outward from the center of the wheel 12 and is secured e.g. by nearby vertical walls. When the axle is supported, the wheel 12 is able to rotate freely.
  • the material of the wheel 12 is also not particularly limiting, but preferably it is made of a metal (such as steel or aluminum), metal alloy or composite material that is able to withstand rigorous activity.
  • FIG. 1 on a first face 13 of the wheel 12, teeth 14 extend outward from the wheel 12 in a lateral direction.
  • the circumference of the circular pattern of the teeth 14 forms a first gear 16 of the mechanical gearbox 10.
  • Figure 2 shows the second face 17 of the wheel 12, where teeth 14 extend outward from the wheel 12 in a lateral direction.
  • the circumference of the circular pattern formed by the teeth 14 on the second face 17 of the wheel 12 form the second gear 18 of the mechanical gearbox 10.
  • the diameter of the first gear 16 is smaller than the diameter of the second gear 18.
  • the ratio of the diameter of the first gear 16 to the second gear 18 is not particularly limiting, and can be adjusted based upon the desired gear ratio of the gearbox 10. Preferably, the ratio it is in the range of 0.75:1 to 0.99:1. In one example, the diameter of the first gear 16 could be about 33.08 inches, where the diameter of the second gear 18 is about 36.61 inches. This ratio of the diameter of the first gear 16 to the second gear 18 is preferably conserved as the size of the mechanical gearbox 10 increases or decreases, and the relative sizes of the first gear 16 and second gear 18 are adjusted proportionately to remain within the preferred ratio.
  • the teeth 14 are produced by drilling holes through the wheel 2 and inserting rods or bolts etc. of a predetermined length through the holes.
  • the teeth 14 protrude away from the wheel 12 sufficient distances to engage the input 22 or output 30 gear.
  • the teeth 14 are produced by affixing rods or bolts etc. to the wheel 14 through a known process, such as welding.
  • the wheel 12 is shown as a unitary piece that has rods extending outward to form teeth 14 that thereby define the first 16 and second gears 18 of the mechanical gearbox 10.
  • gears are contemplated, including known designs of compound gears that would be well understood to the person of skill in the art.
  • the teeth 14 may extend outwardly in a radial direction (not shown), and may be e.g. substantially flat in shape, and parallel to the plane of the wheel 12. Teeth 14 extending radially from the circumference of the wheel 12 would form the second gear 18, whereas another set of teeth 14 would be attached to or molded with the first face 13 of the wheel 12, effectively pointing radially outward, but defining a smaller circumference that would define the first gear 16.
  • two gears of a predetermined size that have teeth 14 extending radially therefrom could be forged together to form the main composite gear of the mechanical gearbox 10.
  • the shape of the teeth 14 is not particularly limiting to the invention, and may have e.g. an involute profile.
  • the design of the teeth 14 should preferably be optimized to efficiently engage the input and output gears.
  • the teeth 14 that extend laterally from the wheel 12 are shown as having a circular transverse cross section that are substantially uniform in width throughout their length.
  • the transverse cross section of these teeth 14 may include square, rectangular, triangular or any other shape.
  • the end of these teeth 14 may be flat or blunt, or they may taper to a rounded or pointed finish.
  • the wheel 12 does not need to be unitary in nature. Rather, two distinct wheels that define both a second 18 and a first 16 gear may be joined together to form the wheel 12 of the mechanical gearbox 10.
  • the number of teeth 14 for each of the first gear 16 and the second gear 18 is related to the diameter of each respective gear.
  • a first 16 and second 18 gear having diameters of 33.08 inches and 36.61 inches respectively, there are about 70 teeth 14 per gear.
  • the relative diameters of the first 16 and second 18 gears may vary, it is not necessary that they have an equivalent number of teeth 14, although if the sizes of the first 16 and second 18 gears permit, it is preferred.
  • the number of teeth 14 on the second gear 18 is a multiple, i.e. 2X, 3X, 4X etc., of the number of teeth 14 on the first gear 16.
  • Motive power is typically provided to the first gear 16 of the mechanical gearbox 10 by engagement with an input gear 22.
  • the input gear 22 illustrated in the Figures comprises two opposing circular end pieces 24 that are joined together by a series or rods 26.
  • the rods 26 attach near the circumference of the end pieces 24, and act as de facto teeth.
  • the number of rods 26/teeth of the input gear 22 may vary, and is typically determined based upon the size of the input gear 22.
  • the embodiment shown in the Figures incorporates eight rods 26 in the input gear 22.
  • An input shaft 28 from an input source 34 such as e.g. a rotor, provides rotational power and drives the rotation of the input gear 22 by e.g. connecting with the center of the input gear 22 to form an axis.
  • the teeth 14 of the first gear 16 mesh with the input gear 22 through insertion of the teeth 14 into the voids between the rods 26.
  • the rods 26 apply a force to the teeth 14 of the first gear 16 causing the wheel 12 to turn about its axis 20.
  • the second gear 18 of the mechanical gearbox 10 engages with an output gear 30 that can be substantially similar to the input gear 22.
  • the output gear 30 illustrated in the Figures comprises two opposing circular end pieces 24 that are joined together by a series or rods 26.
  • the rods 26 attach near the circumference of the end pieces 24, and act as de facto teeth.
  • the number of rods 26/teeth of the output gear 30 may vary, and is typically determined based upon the size of the output gear 30.
  • the embodiment shown in the Figures incorporates eight rods 26 in the output gear 30.
  • an output shaft 32 forms the axis for the output gear 30 and rotates freely to transmit rotational power to the ultimate output device 36, such as e.g. a generator 36.
  • the design and style of the input and output gears 22, 30 is not particularly limiting, and they may have a more traditional form as would be understood by the man skilled in the art.
  • the input and output gears 22, 30 should be of a style, size and orientation to allow for fluid engagement with the teeth 14 of the first and second gears 16, 18.
  • the input and/or output gears 22, 30 comprise a sprocket and chain drive type configuration.
  • the diameter of the input 22 and output 30 gears may vary particularly as the diameter of the wheel 12 is increased or decreased. Although in one embodiment, the output gear 30 has a larger diameter than the input gear 22.
  • the ratio of the input gear 22 to the output gear 30 is not limiting to the invention, and can be designed at a certain ratio necessary to provide a desired gear ratio of the gearbox 10.
  • the ratio of input gear 22 to the output gear 30 could range anywhere from 10:1 to 1 :10.
  • the output gear 30 be of a size that when it rotates in conjunction with the wheel 12 of the mechanical gearbox 10, it rotates at a velocity substantially equal to the rotational velocity of the input gear 22.
  • Such an embodiment would essentially transfer near equivalent speed and torque from an input source to an output source.
  • the figures illustrate in an exemplary manner the input and output gears 22, 30 engaging the first and second gears 16, 18 from a substantially perpendicular orientation.
  • the input and/or output gears 22, 30 may engage the first and/or second gears from any angle, up to where the planes of the input and/or output gears 22, 30 and the first and/or second gears are substantially parallel.
  • One benefit of having the input gear 22 and output gear 30 engage the wheel 12 as illustrated in the Figures, i.e. substantially perpendicular to the wheel 12, is it allows the plane of the wheel 12 of the mechanical gearbox 10 to be substantially parallel to the length of the input shaft 28 and output shaft 32.
  • Such a design makes the mechanical gearbox 10 fairly linear, which can minimize the space required when integrating the mechanical gearbox 10 into a larger system.
  • first 16 and second 18 gears of the wheel 12 comprise differing styles of teeth 14.
  • the second gear 18 may have teeth 14 that are planar and extend radially from the wheel 12, while the first gear 16 may have teeth 14 that extend outward in a lateral direction from the wheel 12.
  • teeth 14 design on the wheel 12 including size and location of the input device 34, e.g. rotor, and/or output device 36, e.g. generator.
  • the input device 34 e.g. turbine and/or output device 36 generator interacts with the mechanical gearbox either substantially in-line or from a lateral direction.
  • the input 22 and output 30 gears may engage the first 16 and second 18 gears of the wheel 12, respectively, at any point along the circumference of the gears.
  • the input gear 22 engages the teeth 14 of the first gear 16 at a point a of from about 0° to about 90° above the horizontal. It has been found that such an engagement angle, i.e. between 0° to about 90° above the horizontal, of the input and output gears 22, 30, with the first and second gears 16, 18 provides for efficient transfer of rotational power.
  • the input gear 22 and/or output gear 30 engage the first gear 16 at a point from about 45° to about 60° above the horizontal.
  • the input gear 22 engages the teeth of the first gear 16 at about 0° to about 90° above the horizontal in the upper right quadrant of the first gear, i.e. at a point about one to two o'clock on the first gear 16.
  • the output gear 30 engages the teeth of the second gear 18 at about 0° to about 90° above the horizontal in the upper left quadrant of the second gear, i.e. at a point between about ten to eleven o'clock on the second gear 18.
  • the input gear 22 engages the teeth of the first gear 16 at about 0° to about 90° above the horizontal in the upper left quadrant of the first gear, i.e.

  • the input and output gears 22, 30 may engage the first and second gears 16, 18 such that they are at opposing ends of the wheel 12.
  • the input gear 22 may engage at about 0° to about 90° above the horizontal in the upper right quadrant of the first gear 16, while the output gear 30 may engage at about 0° to about 90° above the horizontal in the upper right quadrant of the second gear 18.
  • the rotation of the wheel 12 is primarily dependent upon the rotation of the input shaft 28. Accordingly, the wheel may rotate in either a clockwise or counter clockwise direction.
  • the mechanical gearbox 10 preferably rotates in a counter clockwise direction.
  • the wheel 12 rotate in a clockwise direction.
  • gear is not limiting, and may take various forms as would be known in the art.
  • the mechanical gearbox could be designed such that the first and second gears 16, 18 may be spur gears, helical spur gears, herringbone gears, bevel gears, spiral bevel gears, hypoid gears, internal gears, etc. Integrating the aforementioned gear types into the wheel 12 and the input 22 and output gears 30 would be well within the capabilities of the skilled worker.
  • the mechanical gearbox 10 is encased in a gear housing (not shown).
  • the gear housing serves as a case to surround some or all of the components of the gearbox 10 to provide mechanical protection.
