Abstract
The utility model discloses a kind of no cylinder sleeve engine Piston volume tubes, including top compression ring is the wedge-shaped bucket ring partially of steel material, and second gas ring is anti-twist taper-face ring, and oil ring is trapezoidal oily band, and scrap blade lower section and matrix coating are at an angle.Compared with the existing technology, the utility model has broken the traditional design mode (CKS+ steel oil ring) without cylinder sleeve engine piston ring, efficiently solving no cylinder sleeve engine tension, to hurt performance low, the short problem of serious wear, service life, raising engine can significantly be dropped pulls risk, and maximum advantage is to increase substantially the service life of engine and piston ring.
Description
Technical field
The utility model relates to a kind of no cylinder sleeve engine Piston volume tubes, applied to no cylinder sleeve engine technical field.
Background technique
Six or more engine of state, to improve overall performance, engine production quotient releases no cylinder sleeve design, but piston ring one after another
The characteristics of manufacturer usually carries out Piston ring design with original design concept, has ignored no cylinder sleeve, causes engine because of piston ring
Design reasons and many problems generated, cause engine cylinder body pull risk be significantly increased, reduced service life, and repair tired
It is difficult.
Utility model content
Purpose of utility model: the purpose of this utility model is in view of the above technical problems, to provide a kind of no cylinder sleeve engine
Piston volume tube.
Technical solution: in order to achieve the above objectives, technical solutions of the utility model are as follows:
A kind of no cylinder sleeve engine Piston volume tube, including top compression ring are steel material wedge shape bucket ring partially, second gas
Ring is distortion taper-face ring, and oil ring is trapezoidal oily band, and scrap blade lower section and matrix coating are at an angle.
Top compression ring uses steel material, outer round surface nitridation+FDG (diamond equadag coating) processing.Main purpose is:
Using the low-friction coefficient of the nitridation+FDG surface opposing cylinder material handled, avoids piston ring and pull cylinder body (FDG has prominent
Anti-scuffing of cylinder bore energy out), fretting wear is reduced, to greatly improve the service life of piston ring and engine.
Second gas ring uses high-strength alloy cast iron materials.Main purpose is using high strength alloy material with respect to matrix material
The wearability of material improves the service life of piston ring.
Oil ring is greatly lowered oil ring elastic force, reduces abrasion, improved service life of aeroengine using trapezoidal oil band technology.
It is preferred that the angle A is 8 ° ± 4 °, more preferably 8 °.
The utility model provides a kind of mentality of designing suitable for no cylinder sleeve engine piston ring, and no cylinder can be effectively reduced
Set engine pulls the risk of cylinder body, while improving the wearability of piston ring opposing cylinder material, starts to increase substantially
The service life of machine and piston ring.
Technical effect: compared with the existing technology, the utility model has broken the traditional design without cylinder sleeve engine piston ring
Mode (CKS+ steel oil ring) efficiently solves no cylinder sleeve engine tension and hurts that performance is low, and serious wear, service life are short to ask
Topic, can significantly drop raising engine pulls risk, and maximum advantage is to increase substantially the use of engine and piston ring
Service life.
Detailed description of the invention
Fig. 1 is the utility model top compression ring structural schematic diagram；
Fig. 2 is the utility model second gas ring structural schematic diagram；
Fig. 3 is the utility model oil ring structure schematic diagram.
Specific embodiment
Further explanation is made without cylinder sleeve engine Piston volume tube to the utility model with reference to the accompanying drawing.
A kind of no cylinder sleeve engine Piston volume tube, as shown in Figure 1, Figure 2 and Figure 3, including top compression ring 1, second gas
Ring 2 and oil ring 3, the top compression ring 1 are steel material wedge shape bucket ring partially, and second gas ring 2 is distortion taper-face ring, oil ring 3
For trapezoidal oily band, scrap blade lower section and matrix coating are at an angle.
Top compression ring 1 uses steel material, outer round surface nitridation+FDG processing.Main purpose is: utilizing nitridation+FDG
The low-friction coefficient of the surface opposing cylinder material of processing, avoid piston ring pull cylinder body (FDG have anti-scuffing of cylinder bore outstanding
Can), fretting wear is reduced, to greatly improve the service life of piston ring and engine.
Second gas ring 2 uses high-strength alloy cast iron materials.Main purpose is using high strength alloy material with respect to matrix
The wearability of material improves the service life of piston ring.
Oil ring 3 is greatly lowered oil ring elastic force, reduces abrasion, improved service life of aeroengine using trapezoidal oil band technology.
Angle A is 8 ° ± 4 °, preferably 8 °.
The piston ring that the present invention designs is discharged on engine in certain engine works S series state six, three surpass within 500 hours
Test surveys average engine oil consumption < 0.05g/Kw.h, piston air leakage 70L/min, tears machine testing piston ring uneven wear amount < open
0.01mm, cylinder holes abrasion loss < 0.02mm.Without the obvious unusual condition such as scuffing of cylinder bore, carbon distribution, the discharge of engine state six has been fully met
Design requirement.
