transport project by planetary gear trainIn my project, the straps between the cylinder and the domes of the tankare fitted with teeth with straight teeth on each crown with two axes at30° from the verticality of the base and a tapped hole to receive an armwith a tire rim notched for lunar or Martian soiland an electric motor equipped with a pinion adaptable to the outer teethof the crown / outer rolling drive ring.The connection between the toothed strapping and the outer rolling ring ismade by 3 or 4 spur gears (here on model 4) therefore by epicyclic geartrain whose planetary gear (strap ring and the tank) remains stationarythanks to the arms on the ground which serve as anti-rotation stops. Theplanet wheels and the ring gear turn around the fixed sun gear by means ofthe motor pinion meshed with the toothing of each ring gear.By simply removing the screws/axle and the motorized arm, this frees theentire planetary gear set if it has to be removed. The entire assembly isremoved in a single assembly and only the planetary tooth strapping remainson the tank. Or remove only the motorized arm is left this ring around themodule if more useful, but reusable at any time for this tank or another.To move forward or backward in a straight line put the two motors inrotation and to turn, simply vary the speed between the two motors or eventurn around on the spot if the wheels of thearms are changed to "idle" wheels.The geared motors and motors with these pinions and the large teeth of eachouter crown will give very high torques for the transport of the tank, evenheavy, and even on significant slopes on the ground of the moon or Mars.https://en.wikipedia.org/wiki/Epicyclic_gearing[here google traduction french to english : (excuse possible errors intranslation)]TRANSPORT PAR TRAIN EPICYCLOIDAL Dans mon projet, les cerclages entre le cylindre et les dômes de la citerne sont munis de dentures à dents droites sur chaque couronne avec à 30° de la verticalité de la base deux axe et un trou taraudé pour recevoir un bras avec une jante à pneu crantée pour sol lunaire ou martien et un moteur électrique muni d’un pignon adaptable à la denture extérieur de la couronne / anneau extérieur d’entraînement de roulage.
