Abstract
The utility model discloses the wear-resistant air cylinder sleeve of engine of a kind of easily assembling, it comprises cylinder sleeve body and support shoulders.Described cylinder sleeve body middle part is provided with oil hole; Described cylinder sleeve body interior is provided with oil groove; Described oil groove and oil hole communicate; Described this external surface of cylinder sleeve has been provided with wearing layer; Described cylinder sleeve body both sides are respectively arranged with annular projection; Described support shoulders is arranged on the upper end of cylinder sleeve body; The lower end of described cylinder sleeve body is provided with chamfering; The upper end that the lower end of described cylinder sleeve body is positioned at chamfering is provided with angle of deflection.The utility model cylinder liner can effectively increase corrosion resistance and the wearability of cylinder sleeve, has improved the working efficiency of cylinder sleeve, has extended the working life of cylinder sleeve, and effectively reduces the spoilage of cylinder liner.
Description
Technical field
The utility model relates to a kind of internal-combustion engine cylinder liner, relates in particular to the wear-resistant air cylinder sleeve of engine of a kind of easily assembling.
Background technique
At present, along with the raising of people's living standard, automobile enters in huge numbers of families, cylinder liner is as the heart component of internal-combustion engine, and its internal surface forms the firing chamber of internal-combustion engine together with cylinder head bottom surface with piston rod, the linear reciprocating motion of guiding piston, because cylinder liner in use often needs friction, so the abrasion resistance properties requirement to cylinder sleeve is very high, and existing cylinder liner is short most working life, can not meet people's demand.
Model utility content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide the wear-resistant air cylinder sleeve of engine of a kind of easily assembling.
The utility model takes following technological scheme to realize: the wear-resistant air cylinder sleeve of engine of a kind of easily assembling, and it comprises cylinder sleeve body and support shoulders, described cylinder sleeve body middle part is provided with oil hole; Described cylinder sleeve body interior is provided with oil groove; Described oil groove and oil hole communicate; Described this external surface of cylinder sleeve has been provided with wearing layer; Described cylinder sleeve body both sides are respectively arranged with annular projection; Described support shoulders is arranged on the upper end of cylinder sleeve body; The lower end of described cylinder sleeve body is provided with chamfering; The upper end that the lower end of described cylinder sleeve body is positioned at chamfering is provided with angle of deflection; The wearing layer material of described cylinder sleeve body setting is nano-ceramic particle layer; Stretching out of described cylinder sleeve body surface annular projection is highly 0.4mm ~ 1.2mm; Described cylinder sleeve body adopts aluminium-base metal carbide hybrid engine to make with stupalith.
The utlity model has in sum following beneficial effect: the utility model cylinder liner can effectively increase corrosion resistance and the wearability of cylinder sleeve, improve the working efficiency of cylinder sleeve, extend the working life of cylinder sleeve, and effectively reduce the spoilage of cylinder liner, reduced cost and the working strength that has reduced workman.
Brief description of the drawings
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Fig. 2 is structural representation of the present utility model;
Wherein: 1, support shoulders; 2, tool withdrawal groove; 3, oil hole; 4, projection; 5, oil groove; 6, wearing layer; 7, cylinder sleeve body; 8, chamfering; 9, spiral reinforcing rod; 10, angle of deflection.
Embodiment
As shown in Figure 1, the wear-resistant air cylinder sleeve of engine of a kind of easily assembling, it comprises cylinder sleeve body 7 and support shoulders 1, described cylinder sleeve body 7 middle parts are provided with oil hole 3; Described cylinder sleeve body 7 inside are provided with oil groove 5; Described oil groove 5 and oil hole 3 communicate; Described cylinder sleeve body 7 outer surfaces have been provided with wearing layer 6; Described cylinder sleeve body 7 both sides are respectively arranged with annular projection 4; Described support shoulders 1 is arranged on the upper end of cylinder sleeve body 7; The lower end of described cylinder sleeve body 7 is provided with chamfering 8; The upper end that the lower end of described cylinder sleeve body 7 is positioned at chamfering 8 is provided with angle of deflection 10.By adopting such scheme, the setting party of oil hole 3 oiling is carried out in cylinder sleeve body 7 inside, the setting of oil groove 5 can store unnecessary lubricant oil, can make cylinder sleeve body 7 in lubricating status, improve the antifraying property of cylinder sleeve body 7 self, thus the working life of improving this device; Described cylinder sleeve body 7 is provided with angle of deflection 10 and chamfering 8, in the time that cylinder sleeve body 7 assembles, slips in cylinder body along angle of deflection 10, and assembling is simple, easy to use; The annular projection 4 of described cylinder sleeve body 7 outer settings and spiral reinforcing rod 9, can effectively increase the rigidity of cylinder sleeve body 7, improves the non-deformability of cylinder sleeve body 7, can effectively reduce the damage of cylinder sleeve body 7; Wearing layer 6 outside described cylinder sleeve body 7 adopts nano-ceramic particle material to make, and can further improve the wear resistance of cylinder sleeve body.
The above is the utility model embodiment, and the equivalence of doing according to structure, feature and principle described in the utility model application range therefore all changes or modifies, and is included in the utility model patent claim.
