Abstract
The utility model discloses a kind of piston skirt lubrication system, and it includes piston only, and piston only has head and skirt section, it is characterised in that：The periphery in the skirt section is provided with spiral helicine oil-way, and the depth of oil-way is 0.003 0.01mmm, and oil-way width is 0.2 0.3mm.The utility model is not only simple in structure, reliable operation, and can effectively solve the problem that the problem of friction produces polishing scratch between piston skirt and cylinder.
Description
Technical field
It the utility model is related to piston field, more particularly to a kind of piston skirt lubrication system.
Background technology
Charged piston makes piston skirt surface temperature and increased than pressure, can destroy lubricating oil film because explosion pressure increases,
Friction between piston and cylinder is set to increase generation polishing scratch.Therefore it is badly in need of the lubrication between increase piston and cylinder surface.
The content of the invention
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of work simple in construction, reliable operation
Fill in Skirt Lubrication structure.
To achieve the above object, the utility model uses following technical scheme：
A kind of piston skirt lubrication system, including piston only, piston only have a head and skirt section, the skirt section it is outer
Disc is provided with spiral helicine oil-way, and the depth of oil-way is 0.003-0.01mmm, and the width of oil-way is 0.2-
0.3mm。
The cross section of the oil-way is the circular arc that radius is 1.2mm.
The oil-way is molded by turning.
The utility model uses above structure, has the advantages that：By setting spiral helicine lubricating oil in skirt section
Groove, the effect of significant trapped fuel lubrication can be had effect.The utility model is not only simple in structure, reliable operation, and can
Effectively solve the problems, such as that friction produces polishing scratch between piston skirt and cylinder.
Brief description of the drawings
The utility model is described in further details below in conjunction with the drawings and specific embodiments；
Fig. 1 is schematic diagram of the present utility model；
Fig. 2 is the enlarged drawing at A in Fig. 1.
Embodiment
As shown in Figure 1 or 2, the utility model includes piston only 1, and piston only 1 has head 11 and skirt section 12, institute
The periphery for stating skirt section 12 is provided with spiral helicine oil-way 2.
The cross section of oil-way 2 is the circular arc that radius is 1.2mm, and the depth of oil-way 2 is 0.003-
0.01mmm, the width of oil-way 2 is 0.2-0.3mm.Said structure, the size of oil-way 2 is smaller, and not influenceing, piston is whole
The intensity of body at the same time it can also reach oil storage lubrication effect.
Oil-way 2 is molded by turning, has the characteristics of convenient for production and efficient.
The utility model can have effect significant trapped fuel profit by setting spiral helicine oil-way 2 in skirt section 12
Sliding effect.The utility model is not only simple in structure, reliable operation, and can effectively solve the problem that between piston skirt 12 and cylinder
Friction produces the problem of polishing scratch.
