The invention relates to the technical field of engines, in particular to an engine main bearing hole structure and an engine with the main bearing hole structure. The aim is tosolve the technical problems that anexisting engine main bearing hole manufacturing technology is complex, and the maintaining cost is high. In order to achievethe purpose, the engine main bearing hole structure is provided, the main bearing hole structure comprises an engine machine body and a main bearing cover arranged on the machine body, the position, attached to the main bearing cover, of the machine body is provided with a first half bearing hole, and the position, attached to the machine body, of the main bearing cover is provided with a second half bearing hole matched with the first half bearing hole. Themain bearing hole structure further comprises a first bearing bush arranged in the first half bearing hole, and under the situation that the main bearing cover is arranged on the machine body, a mainbearing hole is formed by the first bearing bush and the second half bearing hole. The main bearing hole is formed by the first bearing bush on the machine body and the second half bearing hole formedin the main bearing cover, the manufacturing difficulty of the main bearing hole is lowered, and the maintaining cost of the main bearing hole is reduced.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to a main bearing hole structure of an engine and an engine having the same. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] The main bearing hole of the engine needs to be processed after the main bearing cap is assembled with the body. After processing, each main bearing cap will correspond to the corresponding body one by one, and each main bearing cap can only be applied to one body , if the main bearing cap has quality problems (bumps, scratches, rust, size out of tolerance, casting defects, etc.) There are differences in the material of the body (such as differences in hardness and density). When processing the main bearing cover and the body together, it is not conducive to selecting a tool with appropriate hardness, and the damage to the tool is relatively large when...
