Outer convex cam roller transmission internal combustion engine with any inner tooth difference

Abstract

The invention discloses an outer convex cam roller transmission internal combustion engine with any inner tooth difference, relates to the field of gas power and belongs to a multi-cylinder engine. The invention provides a novel internal combustion engine; eight cylinders are annularly and symmetrically distributed at the periphery of an outer convex multiphase inner cam evenly, so that the force of the outer convex multiphase inner cam is zero; pistons of the cylinders directly act on the outer convex multiphase inner cam by push rods; and power is transmitted to an output shaft which is connected with a center wheel in a key way by the outer convex multiphase inner cam through cam roller oscillating teeth with any inner tooth-difference. The internal combustion engine omits connecting rods and crankshafts of the traditional internal combustion engine; and an outer convex multiphase inner cam roller transmission mechanism does not have eccentric mass and has the advantages of inertia force and working load self-balancing. The rotating speed of the output shaft depends on the transmission ratio of oscillating tooth transmission; if an oscillating tooth carrier is fixed, the center wheel is output in large torque and at the lower speed; and the outer convex cam roller transmission internal combustion engine with any inner tooth difference can be widely used for the fields of engineering and military in need of the high power, such as engineering machinery, armored cars and the like. The internal combustion engine has the advantages of simplicity and compactness in structure, small axial dimension, self-balancing in stress and stability in operation.

Description

technical field [0001] The invention relates to the field of gas power, more specifically, a cam roller 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...

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
