Abstract

Disclosed herein is a revised version of housing wheel engine with method of hypotrochoid that patented U.S. Pat. No. 7,730,869. It keeps the main functions and also provides not only cases Rr≥3 but also cases Rr2 and Rr1, which means it has been able to develop engines as well as four pistons and two pistons, which the previous version cannot do.

Claims1

Dependent claims

A housing wheel engine comprising:

an epitrochoid gear set, said epitrochoid gear set further comprising a fixed annular gear having a radius (R) and a plurality of pairs of rolling outer gears (Rr), said rolling outer gears being spaced evenly about a perimeter of said fixed annular gear, each respective gear of said plurality of pairs of outer rolling gears having a radius (r), whereby Rr is a positive integer, said fixed annular gear and said rolling gears having a pitch ratio defined by R/r, each respective gear of said plurality of pairs of outer rolling gears being engaged with said fixed annular gear and another respective one of said outer rolling gears;
and
an integral housing wheel having a plurality of crankshaft holders and crankshafts each equaling 2*Rr, each of said crankshaft holders having a pair of crankshaft bearing seats and said crankshaft holders receiving a respective axle portion of a respective said crankshaft;
a plurality of I_X holders equaling 2*Rr, each of said I_X holders having a pair of intake-exhaust ports and a spark igniter;
a plurality of arc-shaped housing wheel segments equaling 4*Rr, each of said housing wheel segments having a pair of rectangular through holes configured for flowing gas through respective said arc-shaped housing wheel segments;
wherein each of said crankshaft holders being connected to a respective one of said I_X holders and binding respective said arc-shaped housing wheel segments to form a complete wheel;
a timing set, wherein said timing set comprises a plurality of piston-sets equaling 2*Rr, said plurality of crankshaft holders, said plurality of crankshafts and said epitrochoid gear set;
and further wherein each of said piston-sets being located inside of said housing wheel;
respective ones of each of said piston-sets being connected to respective said rolling gears by respective said crankshafts;
and
a cylindrical driveshaft, said cylindrical driveshaft having a plurality of coupling keys being located at a center of, and engaged together with said housing wheel by said plurality of coupling keys.
