Internal combustion engine with gear-driven crankshaft
09624772 · 2017-04-18 · ·

An internal combustion engine includes a cylinder block defining a cylinder and a crankshaft rotatably received by the cylinder block. The crankshaft includes a crankshaft gear and is configured to rotate along a longitudinal axis of the crankshaft. The engine further includes a piston configured to reciprocate within the cylinder between spaced stroke termination points defining a stroke of the piston. The engine also includes a connecting rod operably coupled to the piston. The connecting rod includes a gear configured to engage the crankshaft gear, wherein the crankshaft gear and the gear of the connecting rod are configured to engage one another, such that as the piston travels within the cylinder, the connecting rod rotates the crankshaft via engagement between the crankshaft gear and the gear of the connecting rod.

Planetary crank gear design for internal combustion engines

A gearset including an internal ring gear; a first pinion gear disposed within the internal ring gear and having teeth meshing with teeth of the internal ring gear; a disc having a central axis collinear with a central axis of the internal ring gear and a slot along a portion of a diameter of a first side thereof; a first pinion shaft having a first end, a second end, and an offset driving lug extending from the second end, the first pinion shaft extending through a hole of the first pinion gear, the offset driving lug of the first pinion shaft engaging with a first end of the slot; a second pinion gear disposed with the internal ring gear and having teeth meshing with teeth of the internal ring gear, the teeth of the second pinion gear not meshing with the teeth of the first pinion gear; a second pinion shaft having a first end, a second end, and an offset driving lug extending from the second end, the second pinion shaft extending through a hole of the second pinion gear, the offset driving lug of the second pinion shaft engaging with a second end of the slot.

There is thus provided, in accordance with achieving a novel embodiment, as a rotary shaft turning force containment. This apparatus has a central component on the outer perimeter of a large circular gear assembly at a distance of its rotary shaft, plurality of individual cylinders such as internal combustion cylinders or steam cylinders are deployed angular acceleration uniformly fixedly attached on the circumference of the said embodiments frame to operate at a distance of said rotary shaft. The rotary shaft at the center of a large circular gear assembly whereby turned by smaller gears by means of linkage therethrough the said cylinders piston rod assembly. The idea behind the cylinders deployed at a distance of the rotary shaft is to take advantage of the mechanical leverage to generate maximum torque force with minimum effort. A microprocessor and associated memory are vital means of controlling rpm in communication with the embodiments.
