The Three-disk-maschine above did correspond to the demands at a small volume, cause there all bearings were put one within the other. At all solutions however, it will make sence to check the inverse possibilities as well, cause often upside-down just will be the better one.
Up to know, e.g. the middle excentric gear wheel was looked at to be fix, later one being transformed to a fix shaft excentric to the system axis. Input and output at the rotor was looked at to be not important, could be installed anywhere at the rotor-arm or cylinder.
Certainly it would be better, to install turning elements at a central shaft and to arrange fix elements outside, into or nearby the fix housing.
Central input and output
The longitudinal-section views of EVDS 02 resp. 03 are analogly, now however inverse shown at picture EVER 01.
The steady turning shaft now will run direct at the system axis (SA), thus now can be mounted well within the housing (GE, German Gehäuse, here first time marked). Rotor-arms (RT) no more are rings, but now can be designed as solide disks. Still, the center of the rotor-arm does show excentrity versus the system axis, here thus the rotor-axis is identical with the excentric axis.
At this longitudinal-section view, again two modules are shown, however the direction of excentrity here differs by 180 degrees. Left side, the excenter-axis is above the system axis, right side below. Corresponding to that, the rotor axis of both rotor-arms are at each excentric axis.
So the central shaft of input and output will be a row of disks, shifted each, practically a steady turning crank-shaft. Between each module it may be beared within the housing (analog to bearings between each cylinder of piston stroke motors), or bearing may but be installed between several modules (like here at both sides of two modules).
Rotor-wheels and excentric-arm
Rotor-wheels (RR) here are unchanged, thus do show a small disk at one side. Within these, a round drilling shows free space for the system shaft. Opposite the effective mass, that disk will support the mass at the system shaft in addition.
Both rotor-wheels here are shown at their outmost track position, thus inertia will be symmetric powers. That system thus is balanced at an axial level (but not at a whole by but two modules).
Also the excentric arms (ET) here in principle are same like above, now however no more beared centrally. Now, the excentric bearing (EL) is arranged direct within the housing (GE), as a slide-bearing around the corresponding excentric axis (EA).
Beds and rings
Thus the housing itself does build (round) beds for the turning excenter-arms. That one, again will be a bed (also round, but itself turning with different speeds) for the rotor-wheel. At the center now, but the crank-shaft will turn steady with its solide rotor-arms. By that inverse arrangement, the motions and power-effects like above are achieved same kind, however input and output are organised much better kind.
On the other hand that picture does tell, these small disks at one side of each rotor-wheel and excenter-arm as well, no more function will have. Originally, these parts should guarantee a more stable shape, especially at the small sides of these ´moon-sickles´. It would make more sence, these elements to construct more stable anyway, like (excentric) rings, all sides sufficiently dimensioned. By light resp. heavy construction, the effectiv mass can also be placed at a center as wanted.
Solide construction
At picture EVER 02 now that new ´Excenterring-Maschine´ is shown. The housing (GE) build the excentric bed of the excentric bearing (EL). Within that, the excenter-arm (ET) will turn, which now is an excentric ring, turning around its excentric axis (EA). Its excentric drilling hole is the bearing of the rotor-wheel (RR), which within that round hole will turn around its center called rotor-excenter-point (RE). Also that rotor-wheel now is shaped like an excentric ring, cause excentrically will also show a drilling hole.
Within that round hole, the rotor-arm (RT) is monted, concentric to the excentric axis (EA), but turning around the system axis (SA). As now, nomore a disk will show towards inside, the central system shaft can show larger diameter. So now, that crank-shaft is stable enough, not at all after each modul a bearing within the housing will be neccessars. As shown here, thus two (or even more) modules may build one assembly-unit.
A modul not at all will be totally unbalanced, cause mass centers of rotor-wheel and of excenter-arm all times will be opposite of the system axis. However they move different, so inertial forces will be balanced but by an assembly of two opposite modules. Some more of these assembly-groups (each with diverse directions of excentrity) will compensate swinging powers at axial direction. Four of these assembly-groups (eight modules as a whole) will be balanced completely. That excenter-ring-maschine thus will run as soft as a combustion motor with same amount of cylinders.
Relation of width and diameter can be quite others than shown here. Effective mass will increase by square to the radius. When here the diameters will be doubled, then an ´Eight-cylinder-engine´ will show a cylindrical shape of 200 mm diameter and same length. Performance of this extremely compact maschine will but depend on turns drived (resp. as fast that maschine can be drived before exploding).
Results
In comparison to the Three-disk-maschine above, these small disks aside the rotor-wheels and excentric-arms as well were neglected. Instead of this, all parts were designed strong enough by itself.
Quite essential however will be, by this excenter-ring-maschine now input and output are arranged central, thus a stable turning crank-shaft can well be mounted within the housing.
Opposite, now the excenter-arms are outside based at the housing, where forces are spread on large slide bearings.
This excenterring-maschine much easier will be to construct, cause all parts now do show simple shape, easy to assemble to units, these may be combined to engines of diverse ´cylinders´.
Compared with this maschine, all concepts above were but logical steps to develope this solution (and by now, none of these designs are really constructed). By the concepts above, step by step that double sling-effect by excentric masses and discontinuous motions were developed. With that excenter-ring-maschine, by now, the most compact shape for these organisational-principles of parts and motions is achieved.So, that excenter-ring-maschine must come true reality - and will create new ´realities´, from bicycle-support-aggregate to home-power-station and far above.
This maschine, in principle does show diverse ´half-moons´ like the crop circle, but these pictures are still not congruent. That excenter-ring-maschine is solide - that crop circle does look more slacken and more light.
Which mental point of views we have to slacken or how can we achieve that lightness of swinging? How can we manage to come near the ideal of that crop circle?
However, at first lets have a look to these confusing approaches of motions by a small Animation.
