The cylinder sleeve of the water-cooled type ring belt is provided, and the upper ring belt position of the cylinder sleeve is provided with a plurality of grooves; the section of the groove is in a circular arc shape; the grooves are semicircular and are uniformly distributed on the circumference of an annular belt on the cylinder sleeve, the starting end and the stopping end of each groove are communicated with the water channel of the cylinder sleeve, and engine cooling liquid can flow into and out of the grooves through the water channels; the depth of the groove bottom is flush with the excircle of the water channel; the radius of the groove does not exceed two thirds of the width of the upper belt of the cylinder sleeve, and the coolant is prevented from seeping out of the upper belt part. The utility model discloses make the upper ring area of wet-type cylinder jacket have partial water-cooling function, can avoid the local high temperature of cylinder jacket, reach the cylinder jacket hole wearing and tearing that reduce this position correspondence and increase cylinder jacket life's purpose.
Description
Technical Field
The utility model belongs to the technical field of the cylinder jacket, mainly provide a cylinder jacket of water-cooled clitellum.
Background
When the fuel engine is in operation, fuel burns in the cylinder sleeve and generates a large amount of heat, the temperature of the combustion chamber can instantaneously exceed 1000 ℃, and the highest temperature area during combustion is positioned in an inner cavity containing the part above the upper ring belt of the cylinder sleeve. In order to prevent the engine from being overheated to cause engine faults when the engine runs, the cylinder sleeve is cooled by using cooling liquid to take away heat.
As shown in fig. 1, the conventional wet type cylinder liner, when installed in an engine for use, has only a water path portion of the cylinder liner that is in contact with a coolant of the engine, and reduces the temperature of the entire cylinder liner by cooling the water path portion of the cylinder liner. The upper ring belt is mainly used for radially positioning the cylinder sleeve in an engine body and preventing cooling liquid from flowing into a tool withdrawal part of the cylinder sleeve to cause the cylinder sleeve to be broken.
Because the above area of the traditional cylinder liner including the upper ring belt cannot be contacted with the cooling liquid, and the area is the highest temperature part of the engine, the temperature of the cylinder liner at the area part is overhigh, so that the excessive dilution of engine oil and the accelerated abrasion of the inner wall of the cylinder liner are caused, and the performance and the service life of the cylinder liner are influenced.
Disclosure of Invention
The utility model aims at providing a cylinder jacket of water-cooled clitellum makes the last clitellum of wet-type cylinder jacket have partial water-cooling function, reduces the local high temperature of cylinder jacket, reaches the cylinder jacket hole wearing and tearing that reduce this position correspondence and increase cylinder jacket life's purpose.
The utility model adopts the following technical proposal for completing the tasks of the invention:
the upper end of the outer diameter surface of the cylinder sleeve is provided with an annular boss, and the annular boss forms an upper annular belt for radially positioning the cylinder sleeve in an engine body; the upper ring belt is provided with a plurality of grooves which are uniformly distributed along the circumference; the groove is semicircular, the starting end and the stopping end of the groove are communicated with the cylinder sleeve water channel, and engine cooling liquid can flow into and out of the groove through the water channel; the depth of the bottom of the groove is flush with the excircle of the water channel; the radius of the groove is not more than two thirds of the width of the upper belt of the cylinder sleeve, so that the coolant is prevented from seeping out of the upper belt part.
The utility model provides a cylinder jacket of water-cooled clitellum adopts above-mentioned technical scheme, and the mode of the last clitellum through part water-cooling wet cylinder cover reduces the cylinder jacket temperature, and the degree of wear that goes up the cylinder jacket hole position that the clitellum corresponds also correspondingly reduces, and the life of cylinder jacket increases 30%.

Fig. 2 is a schematic structural view of the cylinder liner of the present invention in front view and in partial longitudinal section.
Fig. 3 is a partially enlarged structural diagram of a in fig. 2.
FIG. 4 is a cross-sectional view of a trench
In the figure: 1. an upper girdle; 2. a water channel; 3. and (4) a groove.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 2 and 3, the cylinder liner of the water-cooled endless belt has a plurality of grooves 3 at the position of an upper endless belt 1; arranging a groove 3 on the outer circle of the ring belt 1 along the circumferential direction at every 5-10 degrees, wherein all the grooves 3 are uniformly distributed on the outer wall of the ring belt 1; each groove 3 is not connected, the notch interval of the adjacent grooves 3 is 5-10 degrees, and the notches are evenly distributed on the outer wall of the ring belt 1 at intervals.
As shown in fig. 4, the cross section of the groove 3 is semicircular arc, the depth of the arc is the difference between the radiuses of the girdle band 1 and the water channel 2, and the depth of the groove bottom of the groove 3 is flush with the excircle of the water channel 2; the width of the groove 3 is the difference between the diameters of the upper ring belt 1 and the water channel 2.
As shown in fig. 2 and 3, the surface contour of the groove 3 on the outer surface of the ring belt 1 is in a semicircular groove shape with an upward arc, the radius of the groove 3 is 1/2-2/3 of the width of the ring belt 2, and the starting end and the stopping end of the groove 3 are communicated with the cylinder liner water channel 2.
Claims (2)
