Gear chamber cover of crank round sliding block internal-combustion engine, engine block assembly and internal-combustion engine thereof

Abstract

The invention discloses a gear chamber cover of a crank round sliding block internal-combustion engine, which is used for sealing a gear chamber by matching with an engine block and an oil bottom shell of the crank round sliding block internal-combustion engine. The gear chamber cover comprises a crankshaft bearing seat which is arranged thereon and is used for supporting a crankshaft of the internal-combustion engine; a through hole arranged on the bearing seat with a cylindrical structure is used for containing a crankshaft bearing and is called a crankshaft bearing containing hole; when the gear chamber cover is fixedly assembled on the engine block of the internal-combustion engine due to the position of the crankshaft bearing seat on the gear chamber cover, central axes of the crankshaft bearing containing hole of the crankshaft bearing seat on the gear chamber cover and that on the engine block of the internal-combustion engine are located on the same line. The invention can meet the requirement of the gear chamber cover assembled on the engine block of the crank round sliding block internal-combustion engine. In addition, the invention further provides an engine block assembly and an internal-combustion engine of the crank round sliding block internal-combustion engine.

Description

technical field [0001] The invention relates to a motion conversion mechanism of a crank-slider, in particular to a gear chamber cover of a crank-slider internal combustion engine. The invention also relates to a body assembly of a crank circular slider mechanism and an internal combustion engine. Background technique [0002] In conventional internal combustion engines and compressors, the conversion between the reciprocating motion of the piston and the rotational motion of the crankshaft is achieved by a crank-and-rod mechanism. However, in the crank-link mechanism, due to the existence of the connecting rod, the internal combustion engine and the compressor of the crank-link mechanism have defects such as bulky, heavy, and poor balance performance. [0003] In order to solve the problems referred to above, the Chinese patent whose approval announcement date is January 13, 1988 and whose announcement number is CN85200358B discloses a "crank circular slider reciprocating ...

AI Technical Summary

Problems solved by technology

Yet in the internal-combustion engine of crank-slider mechanism, internal-combustion engine is because the structure of body is different with traditional motor, and the mechanism that common internal-combustion engine can be arranged on the body is difficult to be arranged on the body of crank-slider mechanism, otherwise body mechanism will be too complex, impossible to manufacture

In the prior art, obviously no suitable gear chamber cover structure can be used, it is necessary to design a new gear chamber cover
