Abstract
The utility model relates to a wet high-strength thin-wall steel cylinder sleeve of a diesel engine. The utility model is a hollow tube body which is arranged in an installing hole of an air cylinder of a single cylinder diesel engine body or a multicylinder diesel engine body after sheathed with water seal; the hollow tube body of the wet cylinder sleeve is a high-strength alloy steel tube body; the wall thickness of a section of a water cavity corresponding to a water jacket part is thin and is from 2.5 mm to form the wet high-strength thin-wall steel cylinder sleeve. The utility model uses a steel cylinder sleeve with high-strength thin-wall steel structure to replace the original thick-wall structure wet alloy cast iron cylinder sleeve; the thin-wall cylinder sleeve has the advantages of sufficient strength, impact resistance and heat resistance, and correspondingly small cooling water chamber space occupation; because the utility model uses the scheme, the steel cylinder sleeve can obtain a maximum cylinder diameter under the precondition of the definite cooling water chamber size and the definite cylinder pitch of a cylinder body to make a diesel engine obtain a maximum power; the scheme can be widely used on single cylinder or multicylinder diesel engines.
Description
Technical field
The utility model relates to the high-strength thin-walled steel cylinder sleeve of a kind of diesel engine wet type.
Background technique
At present, known water-cooled diesel engine is divided into two big classes by the cylinder sleeve type of cooling: a class is a dry cylinder liner, and complex structure, the anufacturability of this class diesel engine cylinder block is poor, casting wasted product rate height, cost of production height; Another kind of is wet cylinder liner, this traditional wet cylinder liner is made with alloy iron casting, though the cylinder of diesel engine body structure is simple, cost of production is low, but because its wall thickness is thicker, more than 7mm, big so take up room, radiating effect is poor, and the use of this structure is often owing to the restriction of cylinder block cooling water chamber size or cylinder core distance has to use dry cylinder liner.
Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, and a kind of high-strength thin-walled steel cylinder sleeve of diesel engine wet type that can obtain maximum cylinder diameter under the prerequisite of certain cylinder block cooling water chamber size or cylinder core distance is provided.
Technical solution of the present utility model:
The high-strength thin-walled steel cylinder sleeve of a kind of diesel engine wet type, it is a hollow tube 1, after it puts water seal, be installed in the cylinder mounting holes of single cylinder diesel body or multi-cylinder diesel engine body, the hollow tube that it is characterized in that wet cylinder liner is a high strength alloy steel material body, the wall thickness that its corresponding water jacket part water cavity is one section is a thin-walled, and thickness is 2.5-5mm, constitutes the high-strength thin-walled steel cylinder sleeve of wet type.
The utility model replaces the wet type alloy cast iron cylinder sleeve of original thick-walled structure, the existing enough intensity of this thin-wall cylinder casing, impact resistance, heat resistance, the less relatively again space that takies cooling water chamber with the steel cylinder sleeve of high-strength thin-walled steel structure.The utility model replaces former pot type piston ring with the piston ring that cylindrical carries out ceramic osmotic treatment, thereby has solved wear-resisting and the excessive heating phenomenon.Because the utility model adopted such scheme, the steel cylinder sleeve can obtain maximum cylinder diameter under the prerequisite of certain cooling water chamber size of cylinder body or cylinder core distance, make diesel engine obtain maximum power, and this scheme can be widely applied on single cylinder and the multi-cylinder diesel engine.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As Fig. 1, the high-strength thin-walled steel cylinder sleeve of diesel engine wet type of the present utility model, it is a hollow tube 1, after it puts water seal, is installed in the cylinder mounting holes of single cylinder diesel body or multi-cylinder diesel engine body, characteristics of the present utility model are, the hollow tube 1 of wet cylinder liner is a high strength alloy steel material body, and the wall thickness that its corresponding water jacket part water cavity is a section is a thin-walled, and thickness is 2.5-5mm, the best is 2.8-3.2mm, constitutes the high-strength thin-walled steel cylinder sleeve of wet type.Carried out the variation of wall thickness at the Steel Thin-Wall cylinder sleeve after, other correlated parts of diesel engine should be done corresponding change, so that coupling is installed.Among Fig. 1, double dot dash line partly is the section projection line of the main interior outer radius portion of former wet cylinder liner, can find out that thus the outside dimension of the high-strength thin-walled steel cylinder sleeve of the utility model has increase slightly, and its internal diameter size increases greatly.
Because high-strength thin-walled steel cylinder sleeve adopts the high strength alloy steel to make, strengthened wear of piston-rings, thus be provided with one deck pottery permeable formation at the outer round surface of piston ring, to increase its working life.
Because Steel Thin-Wall cylinder sleeve of the present utility model adopts the high strength alloy steel to make, the wall thickness that the corresponding water jacket part water cavity of steel cylinder sleeve is one section is an attenuate, then improved radiating effect greatly, water cavity thickness can correspondingly be reduced, thereby make the internal diameter of Steel Thin-Wall cylinder sleeve can obtain maximum diameter, its installation volume is reduced, widely applicable, all applicable on various diesel engines.Because the surface of piston ring is provided with one deck pottery permeable formation, then improved the wear resistance between steel cylinder sleeve and the piston ring greatly in addition, increase working life.
Claims (3)
1, the high-strength thin-walled steel cylinder sleeve of a kind of diesel engine wet type, it is a hollow tube 1, after it puts water seal, be installed in the cylinder mounting holes of single cylinder diesel body or multi-cylinder diesel engine body, the hollow tube that it is characterized in that wet cylinder liner is a high strength alloy steel material body, the wall thickness that its corresponding water jacket part water cavity is one section is a thin-walled, and thickness is 2.5-5mm, constitutes the high-strength thin-walled steel cylinder sleeve of wet type.
2,, it is characterized in that the wall thickness of one section of the corresponding water jacket part water cavity of Steel Thin-Wall cylinder sleeve is 2.8-3.2mm by the high-strength thin-walled steel cylinder sleeve of the described diesel engine wet type of claim 1.
