Outside-protruding-inside random tooth difference cam moving type transmission combustion engine

Abstract

The invention discloses an outside-protruding-inside random tooth difference cam moving type transmission combustion engine, relates to the field of gas power and belongs to multi-cylinder engines. Eight cylinders of the novel combustion engine are symmetrically and evenly distributed on the circumference of an outside-protruding-inside multiphase inner cam, so that the resultant force exerted on the outside-protruding-inside multiphase inner cam is zero, pistons of the cylinders directly act on the outside-protruding-inside multiphase inner cam through push rods, and motive power is transmitted to an output shaft connected with a central gear by the outside-protruding-inside multiphase inner cam through movable oscillating tooth transmission of a random tooth different inner cam. The combustion engine omits a connection rod and a crank shaft in a traditional combustion engine, and an outside-protruding-inside multiphase inner cam shock wave mobile transmission mechanism has the advantages of having no eccentric mass, and having inertia force and self-balance of working load. The rotating speed of the output shaft depends on the transmission ratio of the oscillating tooth transmission, if an oscillating tooth carrier is fixed, the central gear performs outputting in a low-speed large-torque mode, and the outside-protruding-inside random tooth difference cam moving type transmission combustion engine can be widely applied to engineering machinery, armored cars and the like which need large power and is simple and compact in structure, small in axial dimension, self-balanced in stress and stable in operation.

Description

technical field [0001] The invention relates to the field of gas power, more specifically, a cam-moving transmission internal combustion engine with an outer convex inner arbitrary tooth difference. 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...

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; The structure is complex, and processing, manufacturing, and assembly are relatively difficult; in addition, the internal combustion engine and the transmission device are usually two independent machines, and the internal combustion engine needs to be installed with a transmission for subsequent transmission, resulting in a large volume
