Description
Technical field
The utility model relates to the cylinder sleeve in a kind of motor car engine, relates in particular to the anti-cavitation wet-type cylinder jacket of a kind of high strength.
Background technique
At present; along with scientific and technical development; machine building industry is also in progress at full speed; its special phenomenon such as cavitation pitting that often there will be of because of metal, usually occurs in part and contacts with liquid and have under the condition of relative movement, and wet liner is worked in this case because of it; so very easily there is the phenomenons such as cavitation pitting; not only cause the working life of motor short, and can bring unnecessary trouble, people are badly in need of a kind of wet liner of ability cavitation pitting.
Model utility content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide the anti-cavitation wet-type cylinder jacket of a kind of high strength.
The utility model takes following technological scheme to realize: the anti-cavitation wet-type cylinder jacket of a kind of high strength, and it comprises cylinder liner body, support shoulders and seal ring, the top of described cylinder liner body is provided with outstanding laterally annular boss; The outside on described cylinder liner body top is provided with support shoulders; Described cylinder liner body both sides are respectively equipped with two circular grooves; In described circular groove, seal ring is installed; Between described cylinder jacket support shoulders and upper waistband, be provided with circular arc; Described arc-shaped surface is provided with one deck nonmetallic material elasitic layer; Between described upper waistband and middle waistband, be provided with gap; Described middle gum bag below is provided with annular projection; The lower end of described lower waistband is provided with the size diminishing guide portion of direction outward; On described cylinder liner body surface, be provided with platform reticulate pattern; Described annular boss, guide portion and cylinder sleeve body are integral structure; The circular groove that described cylinder liner body both sides arrange is arranged in parallel; The material of the nonmetallic material elasitic layer of the arc-shaped surface of described cylinder liner body setting is high temperature resistant synthetic fiber.
The utlity model has in sum following beneficial effect: the set nonmetal elasitic layer of the utility model wet liner has effectively played the effect that prevents cavitation pitting; further protection wet liner; and this wet liner is simple in structure, the set platform reticulate pattern of cylinder-barrel surface makes cylinder liner have the advantages such as corrosion-resistant and wear-resistant.
Brief description of the drawings
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, boss; 2, support shoulders; 3, nonmetallic material elasitic layer; 4, upper waistband; 5, seal ring; 6, circular groove; 7, gap; 8, middle gum bag; 9, annular projection; 10, guide portion; 11, platform reticulate pattern; 12, cylinder sleeve body; 13, lower waistband.
Embodiment
As shown in Figure 1, the anti-cavitation wet-type cylinder jacket of a kind of high strength, it comprises cylinder liner body 12, support shoulders 2 and seal ring 5, the top of described cylinder liner body 12 is provided with outstanding laterally annular boss 1; The outside on described cylinder liner body 12 tops is provided with support shoulders 2; Described cylinder liner body 12 both sides are respectively equipped with two circular grooves 6; In described circular groove 6, seal ring 5 is installed; Between described cylinder jacket support shoulders 2 and upper waistband 4, be provided with arc transition; Described arc transition surface is provided with one deck nonmetallic material elasitic layer 3; Between described upper waistband 4 and middle waistband 8, be provided with gap; Described middle gum bag 8 belows are provided with annular projection 9; The lower end of described lower waistband 13 is provided with the size diminishing guide portion 10 of direction outward, thereby makes installation process convenient simple; The described cylinder liner body 12 upper platform reticulate patterns 11 that arrange in surface, in use inject lubricant oil, thereby reduce friction, strengthen its greasy property, subtract gadgety wearing and tearing; The annular projection 9 of described cylinder sleeve body 12 arranged outside, has increased the rigidity of cylinder liner, has improved its ability of anti-deformation, can effectively reduce the damage of cylinder liner; The phenomenons such as the seal ring 5 in described cylinder liner circular groove 6 can effectively prevent from leaking.
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.
