Cylinder jacket based on scale structure

Abstract

The invention provides a cylinder jacket based on a scale structure. A piston moves in the cylinder jacket; the cylinder jacket comprises multiple V-shaped groove sets arranged on the inner surface ofthe cylinder jacket and uniformly distributed in the piston moving direction to form the scale structure; and the V-shaped groove sets comprise multiple V-shaped grooves and multiple transition arcs.The multiple V-shaped groove sets in the scale shape are designed on the surface of the cylinder jacket, so that the oil storage is facilitated, the wear is reduced, and the service life of an engineis prolonged.

Description

technical field [0001] The disclosure relates to the field of friction pair cylinder liner-piston ring assemblies of diesel engines, in particular to a scale-based cylinder liner. Background technique [0002] The cylinder liner is the surface structure of the cylinder liner, which together with the piston and cylinder head form the combustion chamber. During the working process of the engine, the friction and wear between the cylinder liner and the piston ring is very serious, especially when the piston reaches the top dead center, the cylinder liner will be severely worn due to the lack of lubricating oil, which is also the main reason for the failure of the cylinder liner reason. [0003] At present, in order to reduce such wear, most scholars mainly focus on improving the wear resistance of the material itself, and develop coating materials with better wear resistance. There are also some scholars who focus on simple multi-group V-shaped grooves and asperities, which c...

AI Technical Summary

Problems solved by technology

There are also some scholars who focus on simple multiple V-shaped groove groups and asperities, which can improve the wear resistance of the cylinder liner to a certain extent, but cannot meet the needs of use.
