Abstract

The invention discloses an internal combustion engine based on a conversion mechanism of a motion form of double holder-free groove ball bearings and belongs to the field of internal combustion engines. In order to overcome the defects that a conventional internal combustion engine is complex in crankshaft structure, high in demand on material and high in processing difficulty and meanwhile, a complex inertial effect and noises are caused as a connecting rod is complex in stress and motion states, the invention designs an engine based on the conversion mechanism of the motion form of double holder-free groove ball bearings to replace a crank connecting rod mechanism, wherein two cycles and four reciprocating strokes are available when the conversion mechanism rotates a turn and can achievea function of reciprocating with a relative large swing by means of the conversion mechanism of the motion form of double holder-free groove ball bearings. Two extending strokes are separately used for compressing and exhausting and two returning strokes are separately used for combusting to act and performing a suction stroke. Compared with an internal combustion engine formed by a conventionalcrankshaft connecting rod, the internal combustion engine based on the conversion mechanism of the motion form of double holder-free groove ball bearings has the advantages that 1, all the moving parts are axisymmetric rotary parts, so that the internal combustion engine is simple in structure and reliable to operate; 2, the internal combustion engine is simple in motion form: a rotating motion and a reciprocating motion, and noises generated are small; and 3, the processing demands on the parts are low and the parts are easily manufactured.

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 an internal combustion engine device based on a motion form conversion mechanism of double cageless curved groove ball bearings. 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 sma...
