Description
Technical field
The utility model relates to a kind of wet cylinder liner diesel engine, specifically a kind of wet type thin-wall cylinder casing diesel engine with bearing rib.
Background technique
Diesel engine is divided into dry cylinder liner diesel engine and wet cylinder liner diesel engine by its type of cooling, the dry cylinder liner diesel engine has compact structure and can obtain advantages such as maximum cylinder diameter under the prerequisite of certain cylinder diameter, but anufacturability is poor, the cost of production height, and the wet type diesel engine is because its anufacturability is good, cost of production is low, and is widely used.In wet cylinder liner diesel engine (hereinafter to be referred as diesel engine), the size of cylinder sleeve internal diameter has determined the output power of diesel engine, under the prerequisite that does not change cylinder core distance and piston stroke, seek out bigger output power, can increase cylinder diameter by the wall thickness that reduces cylinder sleeve, thereby obtain bigger power output.When the wall thickness of cylinder sleeve reduces, on the one hand its material is required to improve, make manufacture cost increase, on the other hand because in working process of diesel engine; thin-wall cylinder casing all will bear a moment high temperature outburst effect in each work cycle; expand if the cylinder sleeve wall thickness is crossed the thin initial elasticity that will cause, thereby the service behaviour of diesel engine is worsened.For avoiding the generation of this phenomenon, just must make cylinder sleeve keep certain wall thickness, can not expand to guarantee cylinder sleeve because of outburst produces initial elasticity, so increasing, its cylinder diameter still is subjected to bigger restriction.
Summary of the invention
The purpose of this utility model is under the prerequisite that does not change cylinder core distance and piston stroke, provides a kind of and can increase cylinder diameter to greatest extent, can guarantee the novel wet type thin-wall cylinder casing diesel engine of thin-wall cylinder casing proper functioning again.
The technical solution of the utility model is:
A kind of wet type thin-wall cylinder casing diesel engine with bearing rib; thin-wall cylinder casing is installed in the cylinder body and cylinder sleeve mounting hole; the outside at thin-wall cylinder casing is provided with cylinder body water jacket; it is characterized in that being provided with on the inboard wall of cylinder block of cylinder body water jacket and the contacted bearing rib of thin-wall cylinder casing; the easiest expansion arc the when position of bearing rib should be tried one's best near thin-wall cylinder casing work; to guarantee the playing effect of placing restrictions on expansion is to greatest extent brought into play its supporting effect.
The utility model has also been taked following technique measures:
Bearing rib can be in the shape of a spiral, and shape is arranged on the inwall of cylinder body water jacket.To be arranged on the quantity of the bearing rib on the inboard wall of cylinder block of cylinder body water jacket be even number to shape and be symmetrical arranged and be the best in the shape of a spiral.
Bearing rib also can be and is continuous full circle ring-type and is arranged on the inwall of cylinder body water jacket, and should on four angles of bearing rib the water port be set.The quantity that is the bearing rib of continuous full circle ring-type is more than one, two the bests.
Bearing rib also can be the annular support muscle of the band opening that is provided with on the inboard wall of cylinder block of cylinder body water jacket.When cylinder body water jacket had the annular support muscle of the band opening that is provided with on the inboard wall of cylinder block more than two, its opening should stagger, and accepted the uniformity of cooling to guarantee cylinder sleeve, adopted the bearing rib of this structure, and bearing rib then needn't be provided with the water port on four angles.
On the cylindrical (outer surface) of thin-wall cylinder casing, be provided with and the contacted annular boss of bearing rib.
Thin-wall cylinder casing can adopt seamless steel pipe, spheroidal graphite cast iron or the manufacturing of high strength alloy cast iron.
The beneficial effects of the utility model:
1, solves the problem that service behaviour that wet type thin-wall cylinder casing diesel engine causes because of cylinder sleeve expands worsens, improved and improved the service behaviour of wet type thin-wall cylinder casing diesel engine, prolonged the working life of diesel engine.
2, can be implemented under the constant prerequisite of cylinder core distance and piston stroke, can reduce the wall thickness of cylinder sleeve to greatest extent, thereby can increase effective working diameter of cylinder sleeve to greatest extent, improve the output power of diesel engine.
3, enlarged the material using scope of thin-wall cylinder casing, thin-wall cylinder casing not only can use the steel manufacturing, and available with lower-cost made such as spheroidal graphite cast iron, high strength alloy cast irons, thereby can reduce the whole cost of diesel engine.
4, the form of bearing rib can be varied, and except above-mentioned several structures, the manufacturing capacity of visual manufacturing enterprise also is designed to other the structural type that is easy to be shaped, and can adopt above-mentioned a certain structural type, also can adopt the combination of above-mentioned several forms.
