Abstract
The utility model provides an anti-attrition coating for an engine piston skirt part. The coating is arranged on a piston skirt part; multiple rows of small round holes and multiple grooves are formed in the coating; the grooves are connected with the small round holes and are arranged between two adjacent rows of small round holes; the multiple rows of small round holes and grooves are formed in the coating on the basis that the original coating performances are not influenced; the small round holes and the grooves are formed and uniformly distributed in the coating, the oil storage capacity of the skirt part is obviously enhanced, the friction coefficient of the piston skirt part is further reduced, the fuel oil consumption is reduced, the usage amount of a coating material is reduced by the small round holes and the grooves, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of engine piston skirt section Friction-Reducing Coating.
Background technique
Chinese automobile is consumed development at full speed at present, the problems such as energy consumption is too fast, environmental pollution have been brought simultaneously, the technology that performance was discharged, improved in minimizing fuel consume, reduction will become the direction of development from now on, develops in a healthy way all significant to automobile industry.
Reduce fuel consume, improve performance and naturally be unable to do without motor, the each parts of motor need to have the ability that reduces friction factor, especially piston aspect, piston generally comprises piston body, piston body comprises piston top and piston skirt, piston skirt forms the Lower Half of piston body near piston top, conventionally, fuel burns and makes reciprocating motion of the pistons in cylinder, because the firing pressure in cylinder acts on piston, in power stroke and return stroke, piston skirt is pressed on cylinder wall, cause piston skirt or cylinder wall surface abrasion, in order to reduce the wearing and tearing between piston skirt casing wall, except adding oiling agent between piston and cylinder wall, conventionally surface, piston skirt is processed.
Piston skirt surface treatment mode is varied, adopt printed the object that Friction-Reducing Coating reaches reduction friction factor, reduces the friction power loss between piston and cylinder wall more on piston skirt at present, but under running at a high speed, the self-enrichment of oil film coating reduces, its friction factor increases, fuel consume strengthens, and common cladding material consumption is large, and cost height is uneconomical.
Model utility content
The utility model provides the Friction-Reducing Coating of a kind of further reduction piston skirt friction factor.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of engine piston skirt section Friction-Reducing Coating, this coating is arranged on piston skirt, and coating is provided with many row's small sircle holes, offers multiple grooves in described coating.
Further, described groove is arranged between adjacent two row's small sircle holes.
Further, described groove connects multiple small sircle holes successively.
Further, between adjacent two grooves, be provided with two row's small sircle holes.
From above technological scheme, the utlity model has following beneficial effect:
Do not affecting on the basis of original coating performance, in coating, offer many row's small sircle holes and groove, small sircle hole and groove are evenly distributed in coating, significantly strengthen piston skirt surface oil storage performance, and strengthened the anti-excessive wear ability at drying regime friction duty skirt end, and further reduce the friction factor of piston skirt, reduce fuel consume, and the small sircle hole of offering and groove can reduce the use amount of cladding material, reduce production costs.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of engine piston of the utility model skirt section Friction-Reducing Coating.
In figure: 1, coating, 2, piston skirt, 3, small sircle hole, 4, groove, 5, piston top.
Embodiment
Below in conjunction with accompanying drawing, a kind of preferred implementation of the present utility model is described in detail.
The utility model provides the Friction-Reducing Coating in a kind of engine piston skirt section, and this coating 1 main component is molybdenum disulfide, after 2 these coatings of printing of piston skirt, can keep for a long time lubricating status, improves usability, life-saving.Piston comprises piston body, piston body comprises piston top 5 and piston skirt 2, piston skirt is arranged on the lower end of piston top, coating 1 is printed on piston skirt 2, coating 1 is provided with many row's small sircle holes 3 and multiple groove 4, the fore-and-aft distance at adjacent two small sircle hole centers is 1 ± 0.2 mm, lateral separation is 1 ± 0.2mm, the diameter of small sircle hole is 1 ± 0.2mm, the width of groove is 1 ± 0.2mm, this groove connects multiple small sircle holes and is arranged between two row's small sircle holes, is provided with two row's small sircle holes between two grooves.Described small sircle hole 3 and groove 4 play storage part lubricant oil effect, lubricant oil is used as on the lubricant oil supply Friction-Reducing Coating at any time surface of storing, improve the film forming of piston face Friction-Reducing Coating and oil lamella adheres in the time that drying regime rubs durability, lower piston skirt friction factor.
In actual production process, employing thickness is that the template of 60 μ m is carried out printed coating to piston skirt, printing position is installed in this template, and print section is provided with mesh, and template top is provided with block rubber, piston skirt is placed in wet end lower end, resin is layered in template, and then template is moved to the left, and piston is rotated counterclockwise simultaneously, liquid resin is layered on uniformly on piston skirt by the mesh at printing position under the pressure of block rubber, completes the printing of Friction-Reducing Coating.
The above mode of execution is only that preferred implementation of the present utility model is described; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skill in the art make the technical solution of the utility model, all should fall in the definite protection domain of claims of the present utility model.
