Description
Technical field
The present invention relates to a kind of wet liner supporting mechanism, support for each position of wet liner specifically, belong to mechanical structure technical field.
Background technique
Along with the development of internal-combustion engine technology, diesel engine strengthening degree is more and more higher, cost-effectiveness requirement and exhaust index also increasingly stringent.When cylinder liner works as diesel engine, an important kinematic pair, is the vitals of internal-combustion engine.Its amount of deformation decides 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 the structure that upper support adds lower support cooperation.At work, piston ring and cylinder liner do high-speed straight-line back and forth movement to diesel engine, and owing to lacking support in the middle part of cylinder liner, 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.Cylinder liner deformation amount will cause greatly piston ring not seal very well, and machine oil is easily scurried into firing chamber and produced particle, causes particulate emissions level poor; And firing chamber combustion gas easily enters crankcase, the gas leakage of acting can cause fuel consumption rate undesirable; And the consequences such as the conference of cylinder liner deformation amount causes lubricating oil consumption to increase, wearing and tearing cylinder sleeve.These all can cause great impact to the economic performance of diesel engine, and lubricating oil consumption increases and the discharge of harmful substance has direct relation, and these Abgasgesetzs increasingly strict beyond doubt institutes are unallowed.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, thus a kind of wet liner supporting mechanism is provided, under the condition of promotion power ruggedization, increase each position of cylinder liner support, control cylinder cover amount of deformation, and component working life can be increased, adapt to batch production.
According to technological scheme provided by the invention, wet liner supporting mechanism comprises cylinder liner and cylinder block, cylinder liner is positioned at cylinder block, cylinder liner is coaxially connected with cylinder block, it is characterized in that: cylinder liner upper outside is provided with the shaft shoulder in cylinder liner, cylinder block upper inner is provided with support shoulders in cylinder block, and in cylinder liner, the shaft shoulder is positioned in cylinder block on support shoulders, and both closely cooperate formation upper support.In the middle part of cylinder liner, outside is provided with the circular groove of multiple circumferencial direction, in each circular groove, second seal ring is installed, cylinder block inside middle portion is provided with level and smooth cylinder block midfoot support, and cylinder block midfoot support and circular groove to be closely cooperated formation midfoot support by the second seal ring.Cylinder liner lower outside is provided with the shaft shoulder under cylinder liner, and cylinder block lower inside is provided with cylinder block lower support shoulder, and under cylinder liner, the shaft shoulder is positioned on cylinder block lower support shoulder, and both closely cooperate formation lower support.
Further, multiple circular groove is parallel to each other.
Further, the shaft shoulder and cylinder block are provided with the first seal ring between support shoulders to cylinder liner.
Further, circular groove is two.
Compared with the prior art the present invention has the following advantages:
Structure of the present invention is ingenious, reliably, rationally, and the expansion that the effective cylinder liner intermediate portion Yin Gaowen of minimizing, high pressure cause and the cylinder liner dynamic deformation that produces and by producing static deformation when manually installing; Improve the stability of the diesel engine part such as cylinder liner at work; Extend part working life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is I place enlarged view in Fig. 1.
Fig. 3 is II place enlarged view in Fig. 1.
Description of reference numerals: support shoulders, 2.2-cylinder block lower support shoulder, 2.3-cylinder block midfoot support, 3-first seal ring, 4-second seal ring in the shaft shoulder, 1.3-circular groove, 2-cylinder block, 2.1-cylinder block under the shaft shoulder, 1.2-cylinder liner in 1-cylinder liner, 1.1-cylinder liner.
Embodiment
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1, the present invention mainly comprises cylinder liner 1 and cylinder block 2, and cylinder liner 1 is positioned at cylinder block 2, and cylinder liner 1 is coaxially connected with cylinder block 2.Cylinder liner 1 cylinder diameter is: 85 ~ 100mm, is highly: 160 ~ 200mm.Cylinder block 2 adopts HT250 material to make
As shown in Figure 2, cylinder liner 1 upper outside is provided with the shaft shoulder 1.1 in cylinder liner, and cylinder block 2 upper inner is provided with support shoulders 2.1 in cylinder block, and in cylinder liner, the shaft shoulder 1.1 is positioned in cylinder block on support shoulders 2.1, and both closely cooperate formation upper support.The shaft shoulder 1.1 and cylinder block are provided with the first seal ring 3 between support shoulders 2.1 to cylinder liner.Upper support realizes the sealing of cylinder liner top cooling jacket by the first seal ring 3, bears part longitudinal bracing simultaneously.The control of upper support power can be adjusted by the equivalent arm of force size of support shoulders 2.1 in the shaft shoulder in cylinder liner 1.1, cylinder block, and ratio can be 0.3 ~ 0.5 times of impacting force, and general upper support shoulders support force is less than lower support shoulder.In cylinder liner, the shaft shoulder 1.1 diameter is 105 ~ 112mm, and thickness is 5 ~ 8mm.First seal ring 3 adopts mild steel wire or copper product to make, and can produce plastic deformation.
As shown in Figure 3, in the middle part of cylinder liner 1, outside is provided with the circular groove 1.3 of multiple circumferencial direction, and multiple circular groove 1.3 is parallel to each other.Install second seal ring 4 in each circular groove 1.3, cylinder block 2 inside middle portion is provided with level and smooth cylinder block midfoot support 2.3, and cylinder block midfoot support 2.3 and circular groove 1.3 to be closely cooperated formation midfoot support by the second seal ring 4.The sealing of lateral support and cooling jacket is realized by midfoot support.In embodiment as shown in Figure 3, circular groove 1.3 is two.Circular groove 1.3 groove depth 2 ~ 5mm, wide 2 ~ 5mm.Circular groove 1.3 place diameter of cylinder is 100 ~ 110mm.
Cylinder liner 1 lower outside is provided with the shaft shoulder 1.2 under cylinder liner, and cylinder block 2 lower inside is provided with cylinder block lower support shoulder 2.2, and under cylinder liner, the shaft shoulder 1.2 is positioned on cylinder block lower support shoulder 2.2, and both closely cooperate formation lower support.Lower support plays main longitudinal bracing effect.Under cylinder liner, the shaft shoulder 1.2 thickness is 1 ~ 5mm.
The present invention designs ingenious, reliably, rationally, is supported for master with bottom, and upper support is the auxiliary effect playing longitudinal dual-gripper.Effectively can reduce cylinder liner intermediate portion Yin Gaowen, expansion that high pressure causes and the cylinder liner dynamic deformation that produces and by producing static deformation when manually installing, the basis taking into account cylinder sleeve cooling is improved the stability of diesel engine cylinder liner at work, extends correlated parts working life.
