Two-phase inner cam-type sleeve transmission combustion engine

Abstract

The invention provides a two-phase inner cam-type sleeve transmission combustion engine, and relates to the field of gas power, belonging to multi-cylinder combustion engines. The invention provides a novel combustion engine. Eight cylinders are annularly and symmetrically arranged around an externally-protruded internal two-phase inner cam so that resultant force exerted on the externally-protruded internal two-phase inner cam is zero; and a cylinder piston acts on the externally-protruded internal two-phase inner cam directly by a push rod, power is transmitted to an output shaft by transmission of a two-phase inner cam-type sleeve oscillating tooth via the externally-protruded internal two-phase inner cam, and the output shaft is connected with a central wheel key. In the combustion engine provided by the invention, a connecting rod and a crankshaft in a traditional combustion engine are omitted, and a sleeve transmission mechanism of the externally-protruded internal two-phase inner cam has the characteristics of no eccentric mass, inertia force and self-balance of working loads. Rotating speed of the output shaft depends on a transmission ratio of the oscillating tooth; and if a pin rack is fixed, a central wheel outputs low-speed-high torque, so that, the combustion engine provided by the invention can be widely applied to high-power engineering machinery, armored cars and the like. Besides, the combustion engine provided by the invention has the advantages of compact structure, small axial size, self-balance of stress and stability in rotation.

Description

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