Description

Technical Field

[0001] The utility model relates to the technical field of cylinder sleeves, in particular to a cylinder sleeve with strong fracture resistance. Background Art

[0002] Cylinder liner, also known as cylinder liner, is the core working part of an engine or pump; it is embedded in the cylinder barrel of the cylinder body, and together with the piston and cylinder head, it forms a combustion chamber. Its main function is to support the reciprocating motion of the piston therein. Cylinder liner is mainly divided into two categories: dry cylinder liner and wet cylinder liner; the back of dry cylinder liner does not contact cooling water, and has the advantages of simple structure, engine weight reduction, and low heat loss; while the back of wet cylinder liner is in contact with cooling water, which is conducive to engine cooling and small and lightweight, and has good heat dissipation performance and high engine durability. It is particularly suitable for high-performance and high-speed engines, such as aviation, aerospace, large-scale engineering machinery and other fields. In addition, according to different materials, cylinder liners can also be divided into cast iron cylinder liners, aluminum cylinder liners and steel cylinder liners; cast iron cylinder liners have low manufacturing costs and good economy, and are suitable for engines with low performance requirements; aluminum cylinder liners are lighter, more wear-resistant, and have better heat dissipation performance, and are often used in high-end models and racing cars; and steel cylinder liners have excellent rigidity, high temperature resistance, wear resistance and other aspects, and are suitable for high-power engines, such as racing cars and heavy machinery.

However, the strength of the material itself can easily break after repeated friction with the piston for a long time, which can easily lead to damage to the engine during operation and affect the quality of use of the power equipment. Therefore, a cylinder liner with strong fracture resistance is proposed to solve the above problem. Utility Model Content
