Problems solved by technology

[0003] The structure of the part is complex, the shape is like a basin, the wall is thin, and 1 / 3 of the positioning surface of the basin bottom is suspended, the rigidity of the workpiece is poor, and it is variable during processing. 1. At present, increasing the strength of the flywheel shell is mainly achieved by increasing the wall thickness of the flywheel shell and using thick ribs. Although this method improves the strength of the flywheel shell, the overall weight is too large, which is not convenient for installation and use, and it will also increase energy consumption. consumption

Abstract

The present invention relates to the technical field of diesel engines, in particular to a diesel engine flywheel housing, comprising a flywheel housing housing, the flywheel housing housing includes a bottom surface and a side wall surrounding the bottom surface, the rear end of the side wall is connected to the bottom surface, and the bottom surface It is integrally formed with the side wall, and the bottom surface and the side wall form a cavity for accommodating the flywheel. The front end of the flywheel shell shell is provided with a ring of dust-proof mesh positioning ring, and the bottom surface of the flywheel shell is provided with reinforcing ribs, which are integrally formed with the bottom surface of the flywheel shell. The present invention significantly improves the strength of the flywheel shell through the design of the flywheel shell structure and the casting process of the flywheel shell, the design of the rib structure effectively disperses the stress, significantly reduces the stress concentration, and improves the bearing capacity and reliability of the flywheel shell. When the flywheel shell is cast, nickel powder and niobium-titanium alloy are added to the iron powder to increase the strength and toughness of the pig iron. Abrasivity improved by 10‑12% compared to before treatment.

Description

technical field [0001] The invention relates to the technical field of diesel engines, in particular to a diesel engine flywheel housing. Background technique [0002] The flywheel housing is an important basic part of the engine. Its function is to connect the engine and transmission, bear part of the weight of the engine and transmission, protect the clutch and flywheel, and is also a supporting part of the engine. Its structure and processing quality directly affect the performance of the engine. [0003] The structure of the part is complex, the shape is like a basin, the wall is thin, and 1 / 3 of the positioning surface of the basin bottom is suspended, the rigidity of the workpiece is poor, and it is variable during processing. 1. At present, increasing the strength of the flywheel shell is mainly achieved by increasing the wall thickness of the flywheel shell and using thick ribs. Although this method improves the strength of the flywheel shell, the overall weight is t...
