Background technique
Along with the development of internal-combustion engine technology, the diesel engine strengthening degree is more and more higher, and Economy requirement and exhaust index be increasingly stringent also.Important kinematic pair when cylinder liner is worked as diesel engine is the vitals of internal-combustion engine.Its amount of deformation is determining the life cycle of internal-combustion engine to a great extent, and directly affects work, the emission performance of internal-combustion engine.
Traditional wet liner supporting mechanism is that upper support adds the structure that lower support coordinates.At work, piston ring and cylinder liner are done the high-speed straight-line back and forth movement to diesel engine, and because the cylinder liner middle part lacks support, cylinder liner is crossed thermal expansion and produced middle part stroke distortion under high temperature, High Pressure, makes cylinder liner form the structure of the little intermediate drum in two.This phenomenon is more obvious on promotion power ruggedization diesel engine.The cylinder liner deformation amount will cause greatly piston ring finely not seal, and machine oil is easily scurried into firing chamber and produced particle, causes particulate emissions level poor; And the firing chamber combustion gas easily enters crankcase, the gas leakage of acting can cause fuel consumption rate undesirable; And the consequences such as lubricating oil consumption increases, wearing and tearing cylinder sleeve that the conference of cylinder liner deformation amount causes.These all can cause on the economic performance of diesel engine great impact, and lubricating oil consumption increases and the discharge of harmful substance has direct relation, and these increasingly strict beyond doubt Abgasgesetzs institutes are unallowed.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of wet liner supporting mechanism is provided, increases each position of cylinder liner and support under the condition of promotion power ruggedization, control cylinder cover amount of deformation, and can increase component working life, adapt to batch production.
The technological scheme provided according to the utility model, the wet liner supporting mechanism comprises cylinder liner and cylinder block, cylinder liner is positioned at cylinder block, cylinder liner coaxially is connected with cylinder block, it is characterized in that: the cylinder liner upper outside is provided with the shaft shoulder on cylinder liner, the cylinder block upper inner is provided with cylinder block upper support shoulder, and it is upper that on cylinder liner, the shaft shoulder is positioned at cylinder block upper support shoulder, both formation upper support that closely cooperate.The outside, cylinder liner middle part is provided with the circular groove of a plurality of circumferencial directions, second seal ring is installed in each circular groove, cylinder block middle part is inboard to be provided with level and smooth cylinder block middle part and to support, and the cylinder block middle part is supported with circular groove and closely cooperated and form middle part and support by the second seal ring.The cylinder liner lower outside is provided with the shaft shoulder under cylinder liner, and the cylinder block lower inside is provided with cylinder block lower support shoulder, and it is upper that under cylinder liner, the shaft shoulder is positioned at cylinder block lower support shoulder, both formation lower support that closely cooperate.
Further, a plurality of circular grooves are parallel to each other.
Further, be provided with the first seal ring between the shaft shoulder and cylinder block upper support shoulder on cylinder liner.
Further, circular groove is two.
Compared with the prior art the utility model has the following advantages:
The utility model structure is ingenious, reliable, rationally, effectively reduces the expansion that cylinder liner intermediate portion Yin Gaowen, high pressure cause and the cylinder liner dynamic deformation produced and produce static deformation during by artificial installation; Improve the diesel engine stability of the part such as cylinder liner at work; Extended part working life.
