Abstract
The utility model discloses internal-combustion engine cylinder liner, supporting shoulder (1) is established in the upper end of liner body (10), its outer surface establishes waistband (3), water jacket wall (4), lower waistband (5), it is characterized in that: establish tool withdrawal groove (2) between supporting shoulder (1) and upper waistband (3), roll extrusion layer is established on tool withdrawal groove 2 surface; Arrange the conical surface (7) between water jacket wall (4) and lower waistband (5), lower waistband (5) sets the conical surface (6) with lower part; Establish seam (8) in the upper inner of liner body (10) near top dead center place, install flame rings (9) in seam (8), flame rings (9) internal surface slightly protrudes liner body internal surface; Establish at the internal surface of liner body (10) and ooze pottery layer (11), ooze pottery layer (11) dark 0.38 ~ 0.61um.The utility model cylinder liner shoulder intensity is high, and interior surface of cylinder liner wear-resisting property is good, alleviates the wear condition of cylinder liner, decreases machine oil loss and fuel consume, extends cylinder liner working life.
Description
Technical field
The utility model relates to cylinder liner, especially internal-combustion engine cylinder liner.
Background technique
At present, there is following shortcoming in common cylinder liner: 1, disconnected platform phenomenon easily occurs at cylinder liner supporting shoulder tool withdrawal groove place; 2, interior surface of cylinder liner is carried out to the method existing defects of enhancement process, as nitriding treatment easily causes Internal Hole Deformation and nitride layer to come off; 3, firepower temperature distribution on the bank in engine piston top is lower, and fuel here can not Thorough combustion, and easily form carbon distribution, the time has grown the wearing and tearing that can aggravate cylinder liner internal wall.
Summary of the invention
The purpose of this utility model is: provide a kind of internal-combustion engine cylinder liner, its intensity is high, and wear-resisting property is good, long service life, and lubrication oil consumption is little.
Technical solution of the present utility model is: this internal-combustion engine cylinder liner comprises liner body, supporting shoulder is established in the upper end of liner body, its outer surface establishes waistband, water jacket wall, lower waistband, it is characterized in that: establish tool withdrawal groove between supporting shoulder and upper waistband, roll extrusion layer is established on tool withdrawal groove surface.
Wherein, arrange the conical surface between water jacket wall and lower waistband, lower waistband sets the conical surface with lower part.
Wherein, establish seam in the upper inner of liner body near top dead center place, install flame rings in seam, flame rings internal surface slightly protrudes liner body internal surface.
Wherein, establish at the internal surface of liner body and ooze pottery layer, ooze pottery layer depth 0.38 ~ 0.61um.
The utility model has the advantages that: 1, improve its intensity by carrying out roll extrusion process to the tool withdrawal groove of supporting shoulder, preventing cylinder liner to support shoulder place and disconnected platform phenomenon occurs; 2, establish at the internal surface of liner body and ooze pottery layer, enhance cylinder liner wear resistance and indeformable, extend cylinder liner working life; 3, establish seam in the upper inner of liner body near top dead center place, install flame rings in seam, flame rings can strike off carbon deposit, improves cylinder liner abrasion situation, decreases engine motor oil loss and fuel consume; 4, arrange the conical surface between water jacket wall and lower waistband, lower waistband sets the conical surface with lower part, can play leading role when loading body.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 supporting shoulder, 2 tool withdrawal grooves, waistband on 3,4 water jacket wall, 5 times waistbands, 6 times conical surfaces, the conical surface on 7,8 seams, 9 flame rings, 10 liner body, 11 ooze pottery layer.
Embodiment
As shown in Figure 1, this internal-combustion engine cylinder liner comprises liner body 10, and establish supporting shoulder 1 in the upper end of liner body 10, its outer surface establishes waistband 3, water jacket wall 4, lower waistband 5, it is characterized in that: establish tool withdrawal groove 2 between supporting shoulder 1 and upper waistband 3, roll extrusion layer is established on tool withdrawal groove 2 surface.
Wherein, arrange the conical surface 7 between water jacket wall 4 and lower waistband 5, lower waistband 5 sets the conical surface 6 with lower part.
Wherein, establish seam 8 in the upper inner of liner body 10 near top dead center place, install flame rings 9 in seam 8, flame rings 9 internal surface slightly protrudes liner body internal surface.
Wherein, establish at the internal surface of liner body 10 and ooze pottery layer 11, ooze pottery layer depth 0.38 ~ 0.61um.
