ARCOG Rotary Engine for SIADOR Cycle (RP)

(Rapid Prototyping entry)

Here is an example of a constant- 3:4 angular-speed-ratio gear train in which the complex involute or epicycloid is reduced into (or replaced with) two simpler interdependent circular arcs, one for the tooth/cog mating surfaces and the other for the compensating arc path of a wobbling gear center/hub. The featured assembly is a proposed in-wheel propulsion system.

ARCOG is a contraction of “ARC COG” (to denote the cog perfectly circular arc feature as opposed to approximate arc of conventional gear), as well as of three-worded, more definitive phrase “ARea-COntact Gerotor”. (“The word ‘gerotor’ was coined by scholar Myron Hill, and is a contraction of the two words GEnerated ROTOR. Simply put, it means that one of the components is formed (generated) by the shape of the other.” Ref: http://www.gerotor.net/about_gerotors.asp ). Also, ARCOG is an acronym of “Alternating-Rotational-Centerpoints Orbital Gyration” and “Axes of Rotation in Cyclic Orbital Gyration” as its rotor specifically rotates alternately in four axes equidistant around the center of gyration. (SIADOR Cycle likewise means Stratified Introduction, Accumulation and Distension Orbital Reverberation Cycle, of which the detail is virtually proprietary.)

There are two pairs of primary gear-train design (with the four-toothed internal gears rotating slower than their three-toothed external mating gears, akin to conventional gearing system) as well as two more-extraordinary pairs of secondary gear-train design (with the three-toothed internal gears rotating 1 1/3 or 4/3 the speed of their smaller, four-toothed external, mating gears): In total, there are eight gears in this assembly with only three relative gear movements as they are grouped into one-, three- and four-geared components. (Take note: One ring body may constitute both internal and external gears in its corresponding inner and outer features.)

This configuration has a function similar to conventional gerotor, yet its primary gear-train design has a nomenclature that closely resembles to that of ordinary gear as its teeth are visually close to that of jagged spur-gear pump than to rounded gerotor pump. Furthermore, what makes this assembly uniquely distinctive is the area-contact sealing provided by the sliding mating surfaces (including those of secondary gear-train design) as opposed to rolling line-contact mating surfaces of conventional gears, such that this makes it ideal for a more successful and profound engine application. Aside from its Guinness World Records bid for a constant-speed-ratio-profile parallel gear train with highest torque capacity, its unique kinematic characteristics also make it possible to device a far more efficient thermodynamic cycle ever.

The side benefits of this configuration include a very compact and automatic Infinitely-Variable Transmission with reverse action and without the use of conventional gearing system (or with the use of uniquely-inspired gear-train system that pushes the envelope of what’s deemed possible).

Finally, Prince Piston will kneel down on his journal before a steaming Miss Dainty magically twirling between her opposing hula hoops.
