Reciprocating piston type internal combustion engine of crankless connecting rod mechanism

Abstract

The invention discloses a reciprocating piston type internal combustion engine device of a crankless connecting rod mechanism, and belongs to the field of internal combustion engines. Aiming at the disadvantages of a traditional internal combustion engine that a crank structure is complex, material requirements are high, the processing difficulty is high, the force state in a same condition and movement status of a connecting rod are complex, and thus the complicated inertia effect and the noise are caused, according to the reciprocating piston type internal combustion engine device of a crankless connecting rod mechanism, a non-cage curved groove ball bearing is utilized to realize a function of reciprocating motion with a large swing, the non-cage curved groove ball bearing is designed with two cycles and four reciprocating travels per cycle of rotation, two push travels are correspondingly used for compression and exhaust, and the two return travels are correspondingly used for combustion working and an air intake travel. Compared with an internal combustion engine composed of a traditional crank connecting rod mechanism, the reciprocating piston type internal combustion engineof a crankless connecting rod mechanism has the following advantages that 1, all the moving parts are axisymmetric rotary parts with simple structures; 2, the motion form is simple, and only the rotary motion and reciprocating motion are included, and less noises are generated; and 3, the parts are low in processing requirements and are easy to manufacture.

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 internal combustion engine device without a crank connecting rod mechanism. Background technique [0002] An internal combustion engine is a power machine that burns liquid or gaseous fuel in a cylinder and converts the heat energy it releases directly into mechanical power. 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 crankshaft is driven to rotate through the connecting rod, and then the power is transferred from the flywheel end output. When working, the small end of the connecting rod r...

Problems solved by technology

However, the complex structure of the crank, high requirements on materials, and high processing difficulty are unavoidable drawbacks. At the same time, the connecting rod is also subjected to complex forces and motion states. The resulting complex inertial effects and noise are historical propositions that the engine industry needs to continuously improve.
