The invention provides an any-tooth-difference
movable type high rotation speed
internal combustion engine and relates to the field of
combustion gas power. Eight cylinder are annularly and evenly distributed around an outward-protruding inner gear to enable the outward-protruding inner gear to be subjected to zero stress, cylinder pistons directly act on the outward-protruding inner gear through pushing rods, and power is transferred to an output shaft connected with a multiple-phase
shock wave cam key
through transmission of the outward-protruding inner gear and a multiple-phase
cam type moving oscillating teeth. A connecting rod and a
crankshaft in a traditional
internal combustion engine are omitted, an outward-protruding inner multiple-phase
cam type moving transmission mechanism has the advantages of being free of eccentric
mass and having
inertia force and working load self balance, the rotating speed of the output shaft depends on the
transmission ratio of the oscillating teeth, if an oscillating tooth frame is fixed, a multiple-phase
shock wave cam performs high-speed output, and the high rotation speed
internal combustion engine can be widely applied to the field of machines needing high rotation speed, such as a helicopter engine, a small power generator and the like. When the output rotation speed is fixed, emission of harmful gas can be reduced. The any-tooth-difference
movable type high rotation speed internal
combustion engine is simple and compact in structure, small in axial size, self-balancing in stress and stable in operation.
