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 general internal combustion engine and the transmission device are two independent machines, and usually the internal combustion engine needs to install an additional transmission for subsequent speed change, resulting in a large volume

Embodiment Construction

[0035] figure 1 , figure 2 The shown two-phase external cam sleeve type high-speed internal combustion engine consists of a cylinder head (1), an exhaust valve (2), an intake valve (3), a cylinder (4), a cylinder block (5), and a push rod (6) , piston (7), spring (8), roller (9), convex inner ring gear (10), sleeve movable tooth (11), pin frame (12), symmetrical two-phase cam (13), column Pin (14), output shaft (15) etc. are formed. The eight cylinders (4) are evenly distributed around the convex inner ring gear (10) in an axially symmetrical manner, and the angle between two adjacent cylinders is 45°. There is a piston (7) in each cylinder (4), and one end of the push rod (6) is consolidated with the piston (7), and the other end is equipped with a roller (9), and the roller (9) makes the push rod ( 6) The connection with the convex inner ring gear (10) is a rolling friction connection. One end of the spring (8) is fixed on the bottom of the piston (7), and the other end ...

Abstract

The invention discloses a two-phase outer cam sleeve type high-rotational-speed internal-combustion engine, and relates to the field of power of fuel gas. The invention provides a novel internal-combustion engine. Eight cylinders are annularly, symmetrically and uniformly distributed around an outwards convex inner gear ring, so that resultant force from which the outwards convex inner gear ring is suffered is zero; pistons of the cylinders directly act on the outwards convex inner gear ring through push rods; and power is transferred to an output shaft connected with a symmetric two-phase cam through a key by the outwards convex inner gear ring through the drive of a two-phase outer cam type sleeve oscillating tooth. By using the internal-combustion engine, a connecting rod and a crankshaft in a conventional internal-combustion engine are omitted; a two-phase outer cam sleeve driving mechanism of the outwards convex inner gear ring of the internal-combustion engine does not have an eccentric mass; the internal-combustion engine has the characteristic of the self balancing of inertia force and a working load; the rotational speed of the output shaft depends on the drive ratio of the drive of the oscillating tooth; if a dowel pin frame is fixedly arranged, the symmetric two-phase cam carries out output at a high speed; the internal-combustion engine can be widely applied to the field of high rotational speeds, such as engines of helicopters, and miniature engines; and when an output rotational speed is constant, the emission of harmful gas can be reduced. The internal-combustion engine is simple and compact in structure, small in axial dimension and self-balancing in stress, and is stable to run.

Description

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