Abstract
An engine or like apparatus includes a linear-to-rotational motion converting mechanism which emulates an elliptic trammel or ellipsogragh linkage. The apparatus includes at least one cylinder disposed along a first axis and a piston reciprocable in the at least one cylinder along the first axis. Also included is an orbital crankshaft having a piston crank and an orbital shaft, the piston crank having a first end journaled to the piston and a second end, the second end being secured to the orbital shaft, the orbital shaft extending along a second axis perpendicular to the first axis. An output crank has a first end and a second end, the first end of the output crank being journaled to the orbital shaft. An output shaft is secured to the second end of the output crank, the output shaft being rotatable at an angular velocity about a third axis parallel with the second axis and perpendicular to and intersecting the first axis. A timing unit is coupled to the orbital shaft, the timing unit constraining the orbital shaft to rotate about the second axis at an angular velocity equal and opposite to that of the angular velocity of the output shaft. The timing unit includes an epicyclic gear train having one or, preferably, two stages.
