Abstract
The utility model discloses a piston ring, including the ring body, the ring body middle part is seted up and is filled the chamber, it has rubber to fill the intracavity packing, ring body surface from interior to exterior coated in proper order cr primer layer, composite biocoating, crN layer, the chromium layer of composite biocoating for being equipped with the reticulation structure, and inlay in the reticulation and have the diamond particle. The utility model discloses simple structure is equipped with packing rubber on the rampart, reduce the wearing and tearing to the rampart, the molecule cohesion of between coating and piston ring base member can progressively be establish and strengthen on ring body surface from interior to exterior coated in proper order cr primer layer, composite biocoating, crN layer, weakens the stack of composite biocoating internal stress simultaneously to strengthen the cohesion of coating greatly and effectively reduce engine friction merit loss and fuel consumption, inlay the diamond particle in composite biocoating, owing to characteristics such as diamond particle hardness are high, good, the hot load -carrying properties of wearability is good for cladding material has possessed better wearability and geng gao's heat -resisting load performance.
Description
Technical field
The utility model relates to a kind of auto parts machinery, specifically a kind of piston ring.
Background technique
Along with fuel economy index and emission limit set require more and more higher, motor car engine more trends towards high pressure of explosion, high moment of torsion, the design of high heat load direction.The new work engines such as turbosupercharging, high-pressure common rail, EGR are by more employings and design, these new work engine ubiquities: fuel gas temperature is high, gaseous-pressure is large, heat carrying high.Because motor possesses these features, make the operating conditions of piston ring become harsher, the wear resistance of piston ring, anti-scuffing of cylinder bore energy and resistance to heat absorption ability will promote further.
Model utility content
The purpose of this utility model is to provide a kind of piston ring, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A kind of piston ring, include ring body, offer in the middle part of described ring body and fill chamber, rubber is filled with in described filling chamber, described ring body surface is coated with Cr bond coat, composite coating, CrN layer from the inside to the outside successively, described composite coating is the layers of chrome being provided with reticulate structure, and is inlaid with diamond particles in reticulate pattern.
The manufactured materials of described ring body is the one in spheroidal graphite cast iron, alloy cast iron, steel material.
Compared with prior art, the beneficial effects of the utility model are:
The utility model structure is simple, and ring wall is provided with filled rubber, reduces the wearing and tearing to ring wall; Ring body surface is coated with Cr bond coat, composite coating, CrN layer from the inside to the outside successively, progressively can set up and strengthen the molecular binding affinities between coating and piston ring substrate, weaken the superposition of composite coating internal stress simultaneously, thus greatly strengthen the combination force of coating, can play one's part to the full under the operating mode of piston ring-cylinder liner harshness, and effectively reduce engine friction horsepower loss and fuel consume; Mosaic diamond particle in composite coating, due to features such as diamond particles hardness are high, good, the hot load-carrying properties of wear resistance are good, the heat-resisting load performance of coating is possessed better wear resistance and Geng Gao.
Accompanying drawing explanation
Fig. 1 is the structural representation of piston ring.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of piston ring, include ring body 1, offer in the middle part of described ring body 1 and fill chamber 2, be filled with rubber 3 in described filling chamber 2, described ring body 1 surface is coated with Cr bond coat 4, composite coating 5, CrN layer 6 from the inside to the outside successively, described composite coating 5 for being provided with the layers of chrome of reticulate structure, and is inlaid with diamond particles in reticulate pattern.
The present invention adopts special electrochemical deposition mode.First one deck Cr bond coat is electroplated at the periphery of piston ring, then in layers of chrome, etch reticulate structure, then diamond particles is embedded in reticulate pattern, through repeatedly repeating, define chromium-diamond composite layer that one deck is thicker, finally electroplate one deck CrN layer at outermost again.
Due to the present invention's employing is electrochemical method, goes for any piston ring material, comprising: spheroidal graphite cast iron, alloy cast iron, steel material.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
