Abstract
The present invention provides a kind of pistons that multi-turn mesh is equipped in skirt section, including skirt section, annular groove and top surface, a circle aperture is equipped in skirt section and annular groove joint, it is characterised in that: is additionally provided with the multi-turn hole of netted arrangement in piston skirt, the hole of each collar aperture hole ring layer adjacent with other is in staggered distribution；The hole of the circle aperture and first lap of skirt section and annular groove joint is in staggered distribution, i.e., the hole of adjacent ring layer or the center of circle of aperture are spaced the hole of ring layer or the center of circle of aperture on same vertical central axes not on same vertical central axes；And so on the number of the hole count of every circle and circle number in total be to be determined according to the area of piston skirt.A kind of piston that multi-turn mesh is equipped in skirt section of the present invention, in piston skirt, aperture is in netted, is conducive to machine oil by netted hole and quickly flow form oil film and increase lubrication and rapid cooling, realize the abrasion of reduction piston skirt, piston ring and cylinder sleeve.
Description
Technical field
The invention belongs to machinery fields.It is related to piston skirt, and in particular to a kind of piston that multi-turn mesh is equipped in skirt section.
Background technique
The existing original hole in piston skirt is small and few, not formed netted.Lubrication and heat dissipation are insufficient；It is easy to cause piston skirt
The abrasion in portion, piston ring, cylinder sleeve.
Summary of the invention
Aiming at the deficiencies in the prior art, the present invention provides a kind of piston that multi-turn mesh is equipped in skirt section.This hair
The bright problem that not only can solve existing piston lubrication and heat dissipation deficiency, but also solve existing piston and be easy to cause piston skirt
Portion, piston ring, cylinder sleeve abrasion problem.
For above-mentioned purpose, technical solution of the present invention is as follows:
A kind of piston being equipped with multi-turn mesh in skirt section, including skirt section, annular groove and top surface are equipped with one in skirt section and annular groove joint
Aperture is enclosed, is additionally provided with the multi-turn hole of netted arrangement in piston skirt, the hole of each collar aperture hole ring layer adjacent with other is staggered
Distribution；
One circle aperture of skirt section and annular groove joint and the hole of first lap are in staggered distribution, i.e., the hole of adjacent ring layer or aperture
The center of circle is spaced the hole of ring layer or the center of circle of aperture on same vertical central axes not on same vertical central axes；
First lap is arranged multiple holes, and is staggered arrangement with a circle aperture in skirt section and annular groove joint；
A second circle hole fewer than first lap, be also staggered arrangement with first lap；Third circle it is consistent with first lap pore quantity and
It is mutually aligned, and encloses the arrangement that is staggered with second；
4th circle is consistent with the second circle and is also to be staggered in centre with third circle；
And so on the number of the hole count of every circle and circle number in total be to be determined according to the area of piston skirt.
The diameter 2.5mm of the hole, circle and circle interval 5mm, hole and hole interval 7.5mm.
The utility model has the advantages that a kind of piston for being equipped with multi-turn mesh in skirt section of the present invention, in piston skirt, aperture is in netted, is passed through
Netted hole be conducive to machine oil quickly flow formed oil film increase lubrication and rapid cooling, realize reduce piston skirt, piston
The abrasion of ring and cylinder sleeve.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
The skirt section 1- as shown in Figure 1:, 2- aperture, 3- hole, the top surface 4-, 5- annular groove.
Specific embodiment
The present invention is described below with reference to specific embodiments.It will be appreciated by those skilled in the art that these embodiments are only
For illustrating the present invention, do not limit the scope of the invention in any way.
A kind of piston being equipped with multi-turn mesh in skirt section as shown in Figure 1:, including skirt section (1), aperture (2), hole (3), top
Face (4), annular groove (5).
It is equipped with circle aperture (2) in skirt section (1) and annular groove (5) joint, is additionally provided with netted arrangement in piston skirt (2)
The hole (3) of multi-turn hole (3), each collar aperture hole (3) ring layer adjacent with other is in staggered distribution.
One circle aperture (2) and the hole (3) of first lap of skirt section (1) and annular groove (5) joint are in staggered distribution, i.e. adjacent turn
The hole (3) of layer or the center of circle of aperture (2) are spaced the hole (3) of ring layer or the circle of aperture (2) not on same vertical central axes
The heart is on same vertical central axes.
It holds: under circle aperture (2) of piston skirt (1) and annular groove (5) joint, designing multi-turn hole (3), and every
Collar aperture hole (3) and the middle position in upper collar aperture hole (3) are uniformly staggered side by side, are in netted arrangement；
The multiple holes (3) of first lap arrangement, and aperture (2) row of being staggered is enclosed with the one of piston skirt (1) and annular groove (5) joint
Cloth；
Second fewer than the first lap hole (3) of circle is also staggered arrangement with first lap hole (3)；
Third circle is consistent with first lap hole (3) quantity and is mutually aligned, and is staggered arrangement with the second collar aperture hole (3)；
4th circle is consistent with the second collar aperture hole (3) and is also to be staggered in centre with third collar aperture hole (3)；
And so on every circle hole (3) number and circle number in total number be to be determined according to the area of piston skirt (1).
The diameter 2.5mm of the hole (3), circle are spaced 7.5mm with circle interval 5mm, hole (3) and hole (3).
In piston skirt, (1) aperture is in netted, is conducive to machine oil by netted hole and quickly flow to form oil film and increase moisten
Sliding and rapid cooling realizes the abrasion for reducing piston skirt (1), piston ring and cylinder sleeve.
Claims (2)
