Abstract
The utility model provides a cylinder sleeve for a liquid-cooled internal-combustion engine or a compressor, which is mainly characterized in that the excircle of the cylinder sleeve is distributed with spiral grooves and the excircle part of the cylinder sleeve with the spiral grooves forms a slide fit with a cylindrical hole of a machine body so as to form a spiral passageway of the cooling liquid and replace the structure of a casting cooling water jacket. When a cooling medium with certain pressure flows across the spiral passageway by means of forced flowing, the cooling of the cylinder sleeve is realized, thereby, the heating load of the cylinder of the internal-combustion engine or the compressor is reduced. By means of altering the geometric size of the spiral grooves out of the cylinder sleeve and the number of spiral angles or the spiral grooves, favorable cooling effect can be obtained.
Description
The utility model relates to the improvement of the cooling structure of liquid-cooling type internal-combustion engine or compressor cylinder sleeve.
As everyone knows, cylinder sleeve is as the important heat transfer part of internal-combustion engine or compressor operation, and it is bearing the high temperature that the medium transmission comes in the cylinder.In order to reduce the heat load of piston and piston ring, prolong its operating life, between cylinder sleeve cylindrical and body, form cooling water chamber usually, take away the heat of cylinder sleeve through water cavity by cooling water flow.Cooling water chamber is that the cavity by body casting cavity and cylinder sleeve cylindrical constitutes.This structure is used till today, and body casting must be adopted water cavity mud core, complex process not only, and volume weight is increased; The cooling water chamber space that forms between body and the cylinder sleeve on the other hand, make cylinder sleeve not have fulcrum and constraint, when stressed, cylinder sleeve can deform, serious also can cause scuffing of cylinder bore, and lateral thrust can cause that also cylinder sleeve and body produce " cavitation pitting " phenomenon, make the strength member body and the cylinder sleeve of internal-combustion engine, the lost of life during piston high-speed motion.
It is a kind of simple in structure that the utility model provides, obvious results band spiral grooves cylinder sleeve, and purpose is the structure that replaces cooling water chamber with the spiral grooves on the cylinder sleeve as the cooling passage of water or other medium.
The utility model is to realize like this, Design and Machining becomes the screw type flute of single head or bull on the cylinder sleeve cylindrical, have between the cylindrical bore of the cylindrical of spiral groove and body, employing is slidingly matched, cooling liquid is under certain pressure, pass through spiral grooves by force, thereby cylinder sleeve is cooled off.Because body has been cancelled the casting water cavity, thereby has simplified casting technique greatly, has reduced the part volume and weight; Because the cylinder sleeve rigidity is strengthened, kept cylinder sleeve to be interrupted at length direction and contacted, make cylinder sleeve under stress simultaneously, can not deform with body.
Fig. 1 and Fig. 2 are two kinds of structural representations of band spiral grooves cylinder sleeve.1 for cylinder sleeve is installed in plane of orientation on the body among the figure, and 2 is body hole, and 3 is body, and 4 is the cylinder pad, and 5 is osculum, and 6 is body and the endoporus that cooperates of cylinder body, and 7 is cylinder sleeve, and 8 is spiral grooves, and 9 is tool withdrawal groove, and 10 is body hole.
Concrete structure of the present utility model is provided by following drawings and Examples.
Among Fig. 1, cylinder sleeve (7) is installed on the body (3) with plane of orientation (1).Cylinder sleeve (7) cylindrical is processed with opens single head or the multi-head spiral groove of wearing (8), adopts between the cylindrical bore (6) of cylinder sleeve cylindrical and body (3) to be slidingly matched, thereby constitutes spiral goove slot type cooling passage.The cooling liquid with certain pressure with force flow flow into spiral grooves (8) from body hole (2) after, by opening the spiral grooves afterbody of wearing, not by body and directly the osculum (5) from the cylinder pad (4) flows out, and realizes the cooling to cylinder sleeve.
Among Fig. 2, the spiral grooves (8) of cylinder sleeve (7) cylindrical is not opened and is worn and leave tool withdrawal groove (9), and the cooling liquid tool withdrawal groove (9) of flowing through flows out by the hole (10) on the body (3).
By embodiment illustrated in figures 1 and 2, change the spiral grooves size of cylinder sleeve cylindrical, helix angle and spiral grooves number, just can change coolant rate, selected intensity of cooling, thus make dissimilar internal-combustion engines or compressor, obtain better fluid medium cooling effect.
Claims (3)
1, a kind of cylinder sleeve that is used for liquid-cooling type internal-combustion engine or compressor, it is directly installed on the cylinder body, be provided with the cooling liquid passage at the periphery that cooperates with cylinder body, it is characterized in that being shaped on spiral grooves (8) on cylinder sleeve (7) cylindrical, have between the cylindrical bore (6) of the cylinder sleeve excircle part of spiral grooves (8) and body (3) for being slidingly matched.
2, cylinder sleeve according to claim 1 is characterized in that spiral grooves (8) afterbody on cylinder sleeve (7) cylindrical can be opened to wear, and also can not open to wear and leave tool withdrawal groove (9).
3, cylinder sleeve according to claim 1 and 2 is characterized in that the spiral grooves number on cylinder sleeve (7) cylindrical, can be single head, also can be bull.
