Multi-cylinder internal combustion engine device

Abstract

The invention discloses a multi-cylinder internal combustion engine device, and belongs to the field of internal combustion engines. In order to overcome the defects that a crank of a traditional internal combustion engine is complex in structure, high in requirement for materials, high in machining difficulty, the inertia effect and noise are difficult to eliminate and the like, the invention designs the multi-cylinder internal combustion engine with the curved groove ball bearing mechanism replacing a crank-link mechanism. The crankshaft of a common internal combustion engine is replaced with a plurality of pairs of bevel gear shafts, an inner ring of the curved groove ball bearing mechanism is fixedly connected with a horizontal bevel gear, an outer ring is eccentrically and fixedly connected with a piston, reciprocating motion is formed in an air cylinder, and multi-cylinder reciprocating inertia is balanced. Compared with the prior art, the multi-cylinder internal combustion engine has the following advantages that 1, a motion form is simple, and the generated noise is low; 2, the inertia of reciprocating motion is counteracted, and vibration is small; 3, the part machining requirement is low, an existing engine structure is compatible, and the manufacturing is easy.

Description

technical field [0001] The invention relates to a multi-cylinder internal combustion engine device, which belongs to the field of power machinery. Specifically, it relates to a multi-cylinder internal combustion engine device based on a curved groove ball bearing mechanism. Background technique [0002] Common reciprocating piston internal combustion engine core mechanisms are composed of cylinders, pistons, cranks and connecting rods. Since the invention of the reciprocating piston internal combustion engine based on the crank connecting rod mechanism, it has promoted the industrial revolution and the development of transportation technology, and has also brought people comfortable and fast travel convenience. 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 a...

Problems solved by technology

The disadvantage is that after the plunger cylinder is worn, the leakage will affect the reliability of the engine piston return stroke

However, this invention greatly changes the structure of the existing internal combustion engine, which is not conducive to quickly organizing mass production with the existing production line
