Description
Technical field
The utility model relates to automotive engine applications, a kind of cylinder liner particularly used in motor, specifically the anti-cavitation pitting cylinder liner of a kind of wet type.
Background technique
High speed conventional engine, the no matter wet type cooling of open type or enclosed, cylinder liner mostly has cavitation pitting in various degree, general is all locally occur, penetrating cylinder sleeve under serious conditions not say, also there is cavitation pitting in the corresponding body wall in cylinder liner cavitation place, and this is not just replacing cylinder sleeve so simple thing, some diesel engines run cylinder liner soon and just occur cavitation pitting aperture, and what even have just scrapped because of dry seed perforation less than 1,000 hours.Dry seed is the ubiquitous serious problems of middle high speed diesel engine, becomes the matter of utmost importance hindering diesel engine to run well, seriously affects the functional reliability of diesel engine and the working life of cylinder liner.
Summary of the invention
Technical problem to be solved in the utility model is the present situation for above-mentioned prior art, and provides casting convenience, long service life, reliability high and can improve the anti-cavitation pitting cylinder liner of a kind of wet type of cylinder liner strength and stiffness.
The utility model solves the problems of the technologies described above adopted technological scheme: the anti-cavitation pitting cylinder liner of a kind of wet type, comprise liner body, liner body has the casing wall of thickening, the outer peripheral surface first-class radian interval of this liner body is processed with axially extended water cavity groove, the enhancing convex tendon that can strengthen liner body rigidity is formed between two adjacent water cavity grooves, strengthen outer arced surface and the engine cylinder-body Full connected of convex tendon, water cavity groove and engine cylinder mates define the longitudinal cooling water chamber of the even cloth of multiple tracks on liner body outer circumferential face.
For optimizing technique scheme, the measure taked also comprises:
Above-mentioned water cavity groove is U-groove bevel.
Above-mentioned water cavity groove is semi-circular groove.
Above-mentioned engine cylinder-body is processed with sleeve port, and liner body is arranged in sleeve port.
Above-mentioned longitudinal cooling water chamber is made up of the inwall combination of water cavity groove and sleeve port.
The outer arced surface of above-mentioned enhancing convex tendon completely and the inwall Full connected of sleeve port.
Compared with prior art, liner body of the present utility model has the casing wall of thickening, the outer peripheral surface first-class radian interval of this liner body is processed with axially extended water cavity groove, the enhancing convex tendon that can strengthen liner body rigidity is formed between two adjacent water cavity grooves, strengthen outer arced surface and the engine cylinder-body Full connected of convex tendon, water cavity groove and engine cylinder mates define the longitudinal cooling water chamber of the even cloth of multiple tracks on liner body outer circumferential face.The utility model strengthens convex tendon and longitudinal cooling water chamber owing to being formed with on liner body, thus the rigidity of liner body is considerably increased, cylinder liner is out of shape little when piston lateral impact, vibrate little, thus efficiency prevent the cavitation pitting of cylinder liner, extend working life of cylinder liner, and have the advantages that cooling effect better, easily processes and maintain easily.
Accompanying drawing explanation

Fig. 2 is sectional structure schematic diagram of the present utility model;
Fig. 3 is engine cylinder-body sleeve port schematic diagram in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 to Fig. 3 is structural representation of the present utility model.
Reference character is wherein: liner body 1, water cavity groove 1a, enhancing convex tendon 1b, outer arced surface 1c, casing wall 11, engine cylinder-body 2, sleeve port 2a, cooling water chamber 3.
Fig. 1 to Fig. 3 is structural representation of the present utility model, as shown in the figure, the anti-cavitation pitting cylinder liner of a kind of wet type of the present utility model, comprise liner body 1, liner body 1 has the casing wall 11 of thickening, the outer peripheral surface first-class radian interval of this liner body 1 is processed with axially extended water cavity groove 1a, the enhancing convex tendon 1b that can strengthen liner body 1 rigidity is formed between two adjacent water cavity groove 1a, strengthen outer arced surface 1c and engine cylinder-body 2 Full connected of convex tendon 1b, water cavity groove 1a matches with engine cylinder-body 2 and defines the longitudinal cooling water chamber 3 of the even cloth of multiple tracks on liner body 1 outer circumferential face.Wet liner is mainly used on diesel engine at present, wet liner feature is that outer wall directly contacts with cooling water, its maximum advantage is perfect heat-dissipating, cooling evenly, process and assemble all more convenient, but this kind of cylinder liner is easily leaked because of cavitation pitting, when cavitation pitting is serious, also engine body can be had influence on.Show after deliberation, wet liner causes the main cause of cavitation pitting to be: because piston clashes into cylinder sleeve at the volley consumingly, cylinder sleeve is made to produce high frequency transverse vibration, initiation cooling water generation shock wave and high pressure bubble, make cylinder sleeve outer round surface frequently be subject to impact and microscopic electrochemical corrosive action causes.The utility model adopts the cylinder sleeve with larger thickening casing wall 11, and longitudinally the enhancing convex tendon 1b contacted completely with engine body is processed on liner body 1, thus add the rigidity of cylinder sleeve and engine body, thus the dither of liner body 1 can greatly be reduced, make cooling water flow in the cooling water chamber 3 with certain space simultaneously and also can reduce the impact force of cooling water and the formation of bubble, thus enable the utility model serve the effect of anti-cavitation pitting.
In embodiment, water cavity groove 1a of the present utility model is preferably U-groove bevel, or water cavity groove 1a is preferably semi-circular groove.U-groove bevel and semi-circular groove are best bathtub construction.
In embodiment, engine cylinder-body 2 is processed with sleeve port 2a, and liner body 1 is arranged in described sleeve port 2a.Engine cylinder-body 2 of the present utility model according to the requirement of cylinder number, will all process the sleeve port 2a suitable with liner body 1, and the outer arced surface 1c of enhancing convex tendon 1b can fully be contacted with the inwall of sleeve port 2a.
In embodiment, cooling water chamber 3 is combined by the inwall of water cavity groove 1a and sleeve port 2a and forms.
The utility model adopts larger thickening cylinder liner wall thickness, then U-shaped or semicircular water cavity groove is gone out at cylinder liner (liner body) Excircle machining, as cooling water chamber, enhancing convex tendon is then similar to cylinder sleeve cylindrical and adds a circle stiffening rib, engine cylinder-body processes sleeve port entirely, with cylinder liner cylindrical Full connected, this enhance body rigidity and cylinder sleeve rigidity, and cylinder sleeve rigidity directly affects its vibration, by greatly adding large rigidity, be out of shape little during piston lateral impact cylinder sleeve, vibrate little, thus effectively can prevent cavitation pitting.
