Oil supply structure based on precise lubrication of integral piston

Abstract

The invention discloses an oil supply structure based on precise lubrication of an integral piston. The oil supply structure comprises a piston skirt part, a piston head part, a cooling oil cavity, an oil supply channel plane of a piston pin hole and a piston body, wherein the piston head part is arranged in the piston body, a combustion chamber is installed in the position, on one side of the piston head part, of the piston body, the outer wall of the combustion chamber is fixedly connected with the piston skirt part, the cooling oil cavity is formed in the position, below the combustion chamber, in the piston body, the outer wall of the cooling oil cavity is fixedly connected with the piston skirt part, a piston inner cavity is formed in the position, below the cooling oil cavity, in the piston body, the outer wall of the piston inner cavity is fixedly connected with the piston skirt part, and the piston skirt part is mounted in the piston body on one side of the piston inner cavity. According to the oil supply structure for precise lubrication of the integral piston, efficient oil supply is achieved, the utilization rate of lubricating oil is increased, the weight of the piston is reduced, and the bearing strength is improved.

Description

technical field [0001] The invention relates to the technical field of oil supply structure, in particular to an oil supply structure based on integral piston precise lubrication. Background technique [0002] As one of the most important parts of the internal combustion engine, the piston transmits power under the action of high temperature and high pressure for a long time. Its structure and working state directly determine the power, reliability, economy and service life of the internal combustion engine. Due to the continuous improvement of market requirements for internal combustion engines, high power and light weight have become the mainstream of development, followed by new challenges, how to ensure the high power of the piston, and the thermal and mechanical loads brought by high strengthening will accelerate the piston. Friction and wear during the working process lead to a series of fatigue problems and even make the piston invalid. The traditional oil chamber and...
