Two-phase inner cam type swinging transmission internal combustion engine

Abstract

The invention provides a two-phase inner cam type swinging transmission internal combustion engine, which relates to the field of gas motive power and belongs to a multi-cylinder internal combustion engine. The invention provides a novel internal combustion engine, eight air cylinders are annularly, symmetrically and uniformly distributed around an outer convex inner two-phase inner cam, the resultant force of the outer convex inner two-phase inner cam is zero, an air cylinder piston directly acts on the outer convex inner two-phase inner cam through a push rod, and the motive power is transferred to an output shaft connected with a center wheel key through a two-phase inner cam type swinging movable tooth via the outer convex inner two-phase inner cam. The internal combustion engine has the characteristics that a connecting rod and a crankshaft in the traditional internal combustion engine are omitted, and an outer convex inner two-phase inner cam type swinging transmission mechanism does not have the eccentric mass, and has the inertia force and work load self balance characteristic. The rotating speed of the output shaft depends on the transmission ratio of the movable tooth transmission, when the movable tooth frame is fixed, a center wheel realizes low-speed and large-torque output, and the internal combustion engine can be widely applied to engineering machinery, armored car and the like with high-powder requirements. The internal combustion engine has the advantages that the structure is simple and compact, the axial dimension is small, the self balance of the stress is realized, and the operation is stable.

Description

technical field [0001] The invention relates to the field of gas power, more specifically, a two-phase internal cam type swing transmission 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 of...

AI Technical Summary

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 and the crankshaft is relatively large; the impact is large and the vibration is large; and thus cause large mechanical wear and shorten the life of the internal combustion engine; Complex structure, difficult processing, manufacturing, assembly, etc.

[0003] In addition, usually the internal combustion engine and the transmission device are two independent machines, and the internal combustion engine needs to be equipped with a transmission for subsequent speed change, resulting in a bulky
