Two-phase inner cam roller transmission type internal combustion engine

Abstract

The invention provides a two-phase inner cam roller transmission type internal combustion engine relating to the field of gas power and belonging to a multi-cylinder internal combustion engine. The invention provides a novel internal combustion engine; eight air cylinders are symmetrically and uniformly distributed on the circumference of outward-convex inner two-phase cams, so that the resultant force born by the outward-convex inner two-phase cams is zero; an air cylinder piston directly acts on the outward-convex inner two-phase cams through push rods; and the power is transmitted to an output shaft in key joint with a center wheel by the outward-convex inner two-phase cams through two-phase inner cam type roller oscillating teeth. With the adoption of the internal combustion engine, a connecting rod and a crank in the conventional internal combustion engine can be eliminated; and a transmission mechanism of the outward-convex inner two-phase cams has the advantages of no eccentric mass, inertia force and self-balance working load. The rotation speed of the output shaft is determined by a transmission ratio of oscillating tooth transmission; if an oscillating tooth rack is fixedly arranged, the center wheel is output at a low speed and a large torque; the internal combustion engine can be widely used for the fields of engineering and military in need of high power, such as an engineering machine, an armored car and the like. The internal combustion engine has the advantages of simple and compact structure, small axial size, self-balance stress and stable operation.

Description

technical field [0001] The invention relates to the field of gas power, more specifically, a two-phase internal cam roller transmission type internal combustion engine. Background technique [0002] At present, a general internal combustion engine (engine) is composed of a body, a crank connecting rod mechanism, a gas distribution mechanism, a cooling system, a lubrication system, a fuel system, and an ignition system. stroke. The transmission mechanism of this type of internal combustion engine uses a crank-connecting rod mechanism, which transmits the power of the piston to the crankshaft through the connecting rod, and converts the reciprocating linear motion of the piston into the rotary motion of the crankshaft. Because this internal combustion engine presses and drives the crankshaft to rotate by the linear motion of the piston and the planar motion of the connecting rod, there is greater friction between the kinematic pairs, resulting in low transmission efficiency o...

Problems solved by technology

Since this kind of internal combustion engine relies on the linear motion of the piston and the plane motion of the connecting rod to press and drive the crankshaft to rotate, there is a large friction between the motion pairs, resulting in low transmission efficiency of the internal combustion engine.

These existing crankshaft connecting rod type internal combustion engines also have the following main disadvantages: large volume; the unbalanced centrifugal force on the connecting rod an
