Abstract
The utility model belongs to the technical field of the engine and provides an air-cooling diesel or gasoline engine body with a detachable cylinder sleeve, comprising a main body, a cavity opened in the main body, a cylinder line arranged in the cavity of the main body and in tight interference fit with an inner wall of the cavity of the main body, wherein a detachable exchangeable split type component is arranged between the cylinder sleeve and the main body. The air-cooling diesel or gasoline engine body has the following advantages: the detachable exchangeable split type component is arranged between the cylinder sleeve and the main body and during the practical using process and when the diesel or gasoline engine body is worn to a certain extent, it is only necessary to exchange the cylinder sleeve and the main body with a heat radiation fin can be continuously used, thus the thermal conduction problem is solved, the service life of increased by about 50%, the direct use cost is reduced by more than 3/4, therefore the economic burden of the users is lightened, the defect of the prior art that it is necessary to wholly exchange the parts is conquered, the improvement is simple and the effect is obvious.
Description
Technical field
The utility model belongs to technical field of engines, relates to a kind of air-cooled diesel engine or petrol engine body, is specifically related to a kind of air-cooled diesel engine or petrol engine body that changes cylinder sleeve.
Background technique
Present domestic air-cooled diesel engine or petrol engine body have used more than ten million platform, and annual newly-increased use more than 1,000,000, and operating conditions and environmental conditions are relatively poor relatively on farming, forestry, fishing fortune machinery; Existing air-cooled diesel engine or petrol engine body are single piece and form through the die casting heat seal that its periphery has radiating fin, and inner chamber is the piston type active chamber; Piston is done the high speed to-and-fro motion during work in active chamber, because the condition of high temperature, high pressure that is in is worked, lubrication effect is poor; The inwall of body just is worn easily in the process of work like this, so whole machine body is used about 1 year with regard to needing replacing or keeping in repair, because the defective on this monolithic construction maximum; Can only integral replacing during replacing; Cause waste of material, use and maintenance cost are higher relatively, material, environmental cost height.
Summary of the invention
The utility model technical problem to be solved is the present situation to existing technology; And a kind of air-cooled diesel engine or petrol engine body that can change cylinder sleeve that have is provided; In the using process of reality; Only need carry out local replacing when body may wear to a certain degree, thereby alleviate user's economic burden.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of air-cooled diesel engine or petrol engine body that changes cylinder sleeve; Include body; Offer cavity in the described body, it is characterized in that, in the cavity of body, be provided with cylinder sleeve; The tight interference of the cavity inner wall of cylinder sleeve and body is fitted, and described cylinder sleeve and body are the detachable split type parts of changing between the two.
The measure of taking for the optimization such scheme specifically comprises:
In above-mentioned a kind of air-cooled diesel engine or petrol engine body that changes cylinder sleeve, the circumference top of described cylinder sleeve has the flanging of chimb side, offers the step that is plane on the body, and flanging is pressed on the step.Make cylinder sleeve realize radial location like this, prevent that cylinder sleeve from rotating in cavity.
In above-mentioned a kind of air-cooled diesel engine or petrol engine body that changes cylinder sleeve, the outer circumferential sides of described body is along being provided with radiating fin.
In above-mentioned a kind of air-cooled diesel engine or petrol engine body that changes cylinder sleeve, the cavity inner wall interference applying amount of described cylinder sleeve and body is 0.09～0.15mm.
This air-cooled diesel engine or petrol engine body are originally single piece; Maximum improvement structure is a built-in cylinder sleeve in the middle of the inner chamber of body; Make cylinder sleeve and body be the detachable split type parts of changing between the two like this; In the using process of reality, when may wear to a certain degree, only need change cylinder sleeve and get final product, and the body that has a radiating fin just can be proceeded to use.
Compared with prior art, the advantage of the utility model is that through cylinder sleeve and body be the detachable split type parts of changing between the two, in the using process of reality; When may wear to a certain degree, only need change cylinder sleeve and get final product, and the body that has a radiating fin can be proceeded to use, and has not only solved heat conduction problem; And improve working life about 50%; Directly user cost reduces more than 3/4, thereby alleviates user's economic burden, has overcome original whole defective of changing that needs; Improve simply, effect is obvious.
Description of drawings
Fig. 1 originally can change the air-cooled diesel engine of cylinder sleeve or the assembling pre-structure schematic representation of petrol engine body;
Fig. 2 is the structural representation after Fig. 1 assembles.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technological scheme of the utility model is done further to describe, but the utility model is not limited to these embodiments.
Among the figure, body 1; Cavity 2; Cylinder sleeve 3; Flanging 4; Step 5; Radiating fin 6.
As depicted in figs. 1 and 2, originally can change the air-cooled diesel engine or the petrol engine body of cylinder sleeve, include body 1; Dispel the heat for ease; The outer circumferential sides of body 1 offers cavity 2 along being provided with radiating fin 6 in the body 1, in the cavity 2 of body 1, be provided with cylinder sleeve 3; In order to guarantee more thermal conduction effect; Cylinder sleeve 3 is fitted with the tight interference of cavity 2 inwalls of body 1, in order to guarantee certain wearing-in period and prevent body 1 explosion that the cavity 2 inwall interference applying amounts of described cylinder sleeve 3 and body 1 are controlled between 0.09～0.15mm and can reach maximum efficiency.
Here cylinder sleeve 3 is the detachable split type parts of changing with body 1 between the two; The circumference top of cylinder sleeve 3 has the flanging 4 of chimb side, offers the step 5 that is plane on the body 1, and flanging 4 is pressed on the step 5; Make cylinder sleeve 3 realize radial location like this; Prevent that cylinder sleeve 3 from rotating in cavity 2, can certainly use other method, as long as cylinder sleeve 3 is positioned in the cavity 2 of body 1.
During work; When cylinder sleeve 3 may wear to a certain degree, only need change cylinder sleeve 3 gets final product; And the body 1 that has radiating fin 6 can be proceeded to use, and the heat that reciprocating motion of the pistons produces is transmitted on the body 1 through cylinder sleeve 3, conducts on the radiating fin 6 on the body 1 heat is shed again.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spiritual defined scope of the utility model.
