Wear-resistant cylinder body of triangular rotor engine and machining method thereof

Abstract

The invention belongs to the field of internal combustion engines, and provides a wear-resistant cylinder body of a triangular rotor engine and a machining method thereof. The wear-resistant cylinderbody of the triangular rotor engine comprises a cylinder body base body, a transition layer and a wear-resistant layer, the transition layer is arranged on the inner side surface of the cylinder bodybase body, and the wear-resistant layer is arranged on the inner side surface of the transition layer. Compared with the prior art, the wear-resistant cylinder body of the triangular rotor engine andthe machining method thereof have the advantages that the wear resistance of the cylinder body is improved, the transition layer is used for connecting the cylinder body base body and the wear-resistant layer, so that the problem that the wear-resistant layer falls off and the wear resistance is insufficient due to insufficient binding force when the wear-resistant layer and the cylinder body basebody material are directly bonded is solved, and the service life of the engine is prolonged.

Description

technical field [0001] The invention belongs to the field of internal combustion engines, and in particular relates to a wear-resistant cylinder block of a triangular rotor engine and a processing method thereof. Background technique [0002] The triangular rotor engine is a four-stroke internal combustion engine, which is mainly used in the fields of military industry, aerospace and new energy vehicles. The four-stroke work of the internal combustion engine is carried out at the corresponding position of the cylinder block. [0003] When the cylinder is working in the engine, half of the inner cavity of the area is in direct contact with the burning flame, and the other half of the area is in contact with the incoming cold air. The cylinder block is not evenly cooled, and at the same time it is dry-frictioned with the radial seal and withstands its impact Vibration, so the cylinder needs to have high wear resistance, high strength, and high thermal conductivity.

AI Technical Summary

Problems solved by technology

[0004] One of the main problems of the cylinder body at present is that the wear resistance of the cylinder body is insufficient, especially in the high temperature area of ​​the cylinder body, the phenomenon of wear-resistant layer falling off and serious wear is easy to occur. The main reason is that the wear-resistant layer and the aluminum alloy cylinder body base Insufficient material binding force, easy to fall off under high temperature, impact and other harsh environments, insufficient wear resistance, affecting the normal use of the engine, it is necessary to improve the wear resistance of the cylinder block
