Abstract
The utility model discloses a cast-in cast iron cylinder sleeve of internal combustion engines, comprising a cylinder sleeve body, the outer periphery of which is provided with an apparatus used for increasing friction. The cast-in cast iron cylinder sleeve of internal combustion engines of the utility model can be fixedly connected with a cylinder body.
Description
Technical field
The utility model relates to technical field of internal combustion engines, is specifically related to a kind of internal-combustion engine cast-in casting iron cylinder jacket.
Background technique
Internal combustion engine cylinders can be provided with a cylinder sleeve in its cylinder body in casting process, this cylinder sleeve directly is cast in the cylinder body when internal combustion engine cylinders is cast.The cylinder sleeve that uses is all to carry out machining to cylindrical and step at present, again the endoporus of cylinder body and step are carried out machining, and the tolerance fit between the two requires very tight, man-hour and raw-material cost are very high, misoperation just can produce distortion when cylinder sleeve was pressed into cylinder body, directly influenced the quality of diesel engine.
Summary of the invention
The purpose of this utility model provide a kind of can with the internal-combustion engine cast-in casting iron cylinder jacket of cylinder body fixation.
The technological scheme that realizes the utility model purpose is as follows:
Internal-combustion engine cast-in casting iron cylinder jacket comprises the cylinder sleeve body, and the outer peripheral surface of described cylinder sleeve body is provided with the device that is used to increase friction.
Described rubbing device is some spaced apart annular protrusions.
Be spaced apart groove or spiral chute between the described annular protrusion.
Described rubbing device is a burr.
The shape of described burr can be conical, or sharp perverse shape, or mushroom-like.
Adopted such scheme, owing on the outer peripheral surface of cylinder sleeve body, be provided with the device that is used to increase friction, therefore, when internal combustion engine cylinders is cast into cylinder sleeve in the cylinder body in casting process, liquid metal penetrates in the gap on the rubbing device, perhaps rubbing device is inserted in the liquid metal, and liquid metal cooling back forms closely with rubbing device and combines, thus make between cylinder body and the cylinder sleeve be connected firm in the extreme.
Description of drawings
Fig. 1 is the structural representation of first mode of execution of cylinder sleeve of the present utility model;
Fig. 2 is the structural representation of second mode of execution of cylinder sleeve of the present utility model;
Embodiment
With reference to Fig. 1, internal-combustion engine cast-in casting iron cylinder jacket of the present utility model comprises cylinder sleeve body 10, and the outer peripheral surface of described cylinder sleeve body is provided with the device that is used to increase friction.This rubbing device is some spaced apart annular protrusions 11, and the interval 12 between the annular protrusion 11 is groove or spiral chute.Annular protrusion can be by the mode moulding of machining, and promptly the outer surface at cylinder sleeve body 10 processes interval 12, and the part between the interval just is shaped to projection in twos.When internal combustion engine cylinders was cast into cylinder sleeve in the cylinder body in casting process, liquid metal penetrated in the interval 12.
With reference to Fig. 2, described rubbing device is a burr 13, and the height of described burr is 0.1mm-1.2mm, and the height of burr is 0.5mm.The shape of burr can be conical, or sharp perverse shape, or mushroom-like, and what adopt in the present embodiment is conical.When internal combustion engine cylinders was cast into cylinder sleeve in the cylinder body in casting process, burr 13 penetrated in the liquid metal.
Cylinder sleeve of the present utility model also has following characteristics except that having above structure:

2. circle working surface piston ring travel scope is 163HBW-302HBW in the cylinder sleeve, and the hardness of same the interior circle of cylinder sleeve working surface is less than or equal to 20HBW.
3. the material metallographic structure in the cylinder sleeve internal circular surfaces piston ring travel scope meets relevant criterion or product design document regulation.
4. the circularity of cylinder sleeve internal circular surfaces is not more than 0.10mm, and upper-end surface, lower end surface are to moving 11 grades of meeting the GB/T1184-1996 regulation of the tip to face distance of internal circular surfaces center line.
5. the roughness Ra of spiral chute shape cylinder sleeve outer round surface is 5 microns to 12.5 microns, and all the other component R a are less than or equal to 12.5 microns.
6. the roughness Ra of burr shape cylinder sleeve and other each finished surface of surface structure cast-in cylinder sleeve is less than or equal to 12.5 microns.
7. inside and outside circular surfaces of cylinder sleeve and end face do not have crackle, be full of cracks, corrosion, damage and casting defect, but under the condition that does not influence usability, allow following defective to exist:
A, the sand holes diameter maximum of outer round surface is no more than 0.5mm, and the degree of depth is less than 0.5mm, and quantity is no more than 3, and spacing is not less than 6mm, every square centimeter no more than 2.
B, length is less than 0.25mm on the internal circular surfaces, and the degree of depth can be omitted less than the eyelet of 0.15mm and be disregarded, but does not allow to exist the dense eyelet; The sand holes diameter maximum of internal surface is no more than 0.5mm, and the degree of depth is less than 1mm, and quantity is no more than 4, with being not less than every square centimeter no more than 2 of 6mm.
