Abstract
The utility model relates to a two-layer slope piston ring which is suitable for various internal combustion engines and compression machines. The utility model is composed of two trapezoidal slope split rings which have the same structure. Because the two split rings are designed into trapezoidal slope and the opening positions of the two split rings are kept at 180DEG, the blowby phenomenon of the opening positions can be eliminated. The split rings are designed into slope rings which have definite height ratio, and the elastic force of the spilt rings can be enhanced; thus the gap of the split rings can be compensated automatically because the split rings are worn out, and the compression performance is enhanced. The utility model has the advantages of novel and simple structure, and stable performance.
Description
The utility model is a kind of double-deck inclined-plane piston ring that is applicable to all kinds of internal-combustion engines, compressed machinery.
Relevant by retrieval patent documentation does not retrieve the double-deck inclined-plane piston ring identical with the utility model structure at present as yet.Piston ring in existing internal-combustion engine, the gas medium compressed machinery mainly contains the individual layer class piston ring of a groove one ring structure and the double-deck class piston ring of a groove two rings.The individual layer piston ring, though simple in structure, because after long-term the use, piston ring scuffing is serious, opening increases, and sealability is descended.Existing double-deck class piston ring though increase aspect the gap-clearance of piston rings place gas leakage preventing, is difficult to guarantee for two-piston ring opening staggered positions, and because after the piston ring scuffing, the gap increases, and sealability reduces, and makes internal-combustion engine, compressed machinery decreased performance in use for some time.
The purpose of this utility model is will provide a kind of can effectively guarantee two-piston ring opening staggered positions, has the double-deck inclined-plane piston ring in automatic compensating piston ring in wearing and tearing back and cylinder body gap.
Technical characteristics of the present utility model is: do not change on the basis of piston and housing structure considering, to be designed to by the double-deck inclined-plane piston ring that trip ring I, trip ring II form.It is characterized in that: trip ring I, trip ring II are the identical trapezoidal inclined-plane trip ring of structure, and two rings are combined into one group by the inclined-plane contact, use in pairs.After loading onto this double-deck inclined-plane piston ring on the piston, because two trip rings can stablize on the position that remains on 180 ° two trip ring aperture positions by the contact of trapezoidal inclined-plane.Piston ring pressurized air when to-and-fro motion enters and refers to the crack, and two trip rings are closely being matched along opening radial direction and cylinder body.The ratio that two trip rings are designed to opening height and inclined-plane peak height is after between 1: 3～1: 8, and the elasticity of ring strengthens, at the volley the gap between compensate for wear back piston ring and the cylinder body automatically.
The utility model has the advantages that:, make the aperture position of two rings remain on 180 ° position, thereby eliminated the blowby phenomenon of opening because two trip rings are designed to trapezoidal inclined-plane trip ring; Because trip ring is designed to the oblique ring of certain altitude ratio, has strengthened the elastic force of ring, thereby can compensate the gap that occurs because of the back of wearing and tearing automatically, reduced the blowby phenomenon of cylinder body and piston ring, improved compression performance, because novel structure is simple, stable performance, so very big promotional value is arranged.
Below with reference to description of drawings embodiment of the present utility model:
Accompanying drawing 1 is the structural representation of the double-deck inclined-plane of the utility model piston ring.
Accompanying drawing 2 is two-piston ring structural representations when staggering mutually.
With reference to accompanying drawing 1, trip ring I[1], trip ring II[2] be the identical trapezoidal inclined-plane trip ring of structure, opening is at the lowest part on trapezoidal inclined-plane, the ratio of opening height and inclined-plane peak height is between 1: 3～1: 8, two rings are combined into one group by the inclined-plane contact, use in pairs.
With reference to accompanying drawing 2, trip ring I[1], trip ring II[2] opening is mutually 180 ° when staggering mutually on the plane.
Claims (2)
1, a kind of double-deck inclined-plane piston ring is by trip ring I[1], trip ring II[2] form, it is characterized in that: trip ring I[1], trip ring II[2] be the identical trapezoidal inclined-plane trip ring of structure, two rings are combined into one group by the inclined-plane contact, use in pairs.
2, double-deck inclined-plane according to claim 1 piston ring is characterized in that: trip ring I[1], trip ring II[2] ratio of opening height and inclined-plane peak height is between 1: 3～1: 8.
