[0003] Such a structure puts forward higher requirements on the cylinder, especially the inner wall of the cylinder. After the cylinder is cast and formed, the inner wall must be polished and smooth, and carburizing and other processes to improve its high temperature and wear resistance must be carried out. Therefore, the manufacturing cost of the cylinder higher

Embodiment Construction
[0010] Such as figure 1 As shown, the high-temperature wear-resistant cylinder structure described in the embodiment of the present invention includes a cylinder 1 and a piston 2, and a cylinder inner sleeve 3 is installed on the inner wall of the cylinder, and an interference is used between the cylinder inner sleeve 3 and the inner wall of the cylinder. Cooperate, when the cylinder 1 is at a high temperature above 300°C, put the cylinder liner 3 in the normal temperature state into the cylinder 1, the thickness of the cylinder liner 3 is 3-5mm, and the cylinder liner 3 is made of high temperature resistant Made of grinding material, the inner surface of the cylinder liner 3 is smoothed, and the outer surface of the cylinder liner 3 and the inner wall of the cylinder are treated with friction to ensure that the cylinder liner 3 will not Sliding from the cylinder, the piston 2 is installed in the cylinder inner sleeve 3, and the cylinder inner wall area corresponding to the to...

A high-temperature wear-resistant cylinder structure comprises a cylinder and a piston. A cylinder inner sleeve is mounted on the inner wall of the cylinder and is in interference fit with the inner wall of the cylinder, the inner surface of the cylinder inner sleeve is in smoothing treatment, both the outer surface of the cylinder inner sleeve and the inner wall of the cylinder are in rubbing treatment so as to guarantee that the cylinder inner sleeve cannot slip from the cylinder after the cylinder inner sleeve is mounted in the cylinder, the piston is mounted in the cylinder inner sleeve, and the cylinder inner sleeve is arranged in regions, corresponding to an upper stop point and a lower stop point of the piston, on the inner wall of the cylinder. The high-temperature wear-resistant cylinder structure has the advantages that wear resistance of the cylinder at high temperature is realized creatively, the cylinder inner sleeve made of a high-temperature wear-resistant material is mounted between the cylinder and the piston, cost for the cylinder in casting and high-temperature wear-resistant treatment processes can be greatly lowered, and wear resistance of the cylinder at the high temperature can be enhanced.
Description
technical field [0001] The invention relates to a high-temperature wear-resistant cylinder structure, which belongs to the field of power system engines. Background technique [0002] Common cylinder-piston structures in the engine field at present are all designed with a clearance fit between the cylinder and the piston, and a sealing ring is arranged between the cylinder and the piston for sliding sealing. [0003] Such a structure puts forward higher requirements on the cylinder, especially the inner wall of the cylinder. After the cylinder is cast and formed, the inner wall must be polished and smooth, and carburizing and other processes to improve its high temperature and wear resistance must be carried out. Therefore, the manufacturing cost of the cylinder higher. Contents of the invention [0004] The purpose of the present invention is to solve the problem that the inner wall of the cylinder requires high temperature and wear resistance, and to provide a high temp...
