Reciprocating piston type internal combustion engine

Abstract

The invention discloses a reciprocating piston type internal combustion engine device, and belongs to the field of internal combustion engines. In order to overcome the defects that a traditional internal combustion engine is complex in crank structure, high in material requirement, high in machining difficulty, capable of causing complex inertia effect and noise and the like, according to the reciprocating piston type internal combustion engine, the internal combustion engine which is characterized in that a rotating movement and reciprocating rectilinear movement switching mechanism is usedfor replacing a crank connecting rod mechanism is designed, wherein the rotating movement and reciprocating rectilinear movement switching mechanism is formed by a retainer-free curved groove ball bearing and a spring, once the retainer-free curved trench ball bearing rotates by one cycle, two-period circulations and four round strokes can be generated, the two extending strokes are used for compression and exhaust, and the two return strokes are used for combustion acting and suction stroke. Compared with the traditional internal combustion engine composed of the crank connecting rod mechanism, the reciprocating piston type internal combustion engine has the following advantages that 1, moving parts are all axisymmetric rotary parts, so that the structure is simple; 2, the movement form is simple and only comprises the rotating movement and the reciprocating movement, so that the generated noise is low; and 3, the machining requirements of the parts are low, so that manufacturing is easy.

Description

technical field [0001] The invention relates to an internal combustion engine device, which belongs to the field of power machinery. Specifically, it relates to a reciprocating piston type internal combustion engine device based on a rotary motion and reciprocating linear motion conversion mechanism composed of a curved groove ball bearing without a cage and a spring. Background technique [0002] Nearly 150 years ago, the German Otto invented the reciprocating piston four-stroke internal combustion engine, which burns liquid or gaseous fuel in the cylinder and converts the heat energy released into mechanical power directly. Common reciprocating piston internal combustion engines are mainly composed of cylinders, pistons, cranks and connecting rods. The cylinder is a space to realize the working cycle and generate power; the piston can reciprocate in the cylinder liner, the fuel is burned in the cylinder, and the power generated pushes the piston to reciprocate, and the cr...
