Description

A kind of novel piston ring

Technical field

The invention belongs to piston field, especially a kind of novel piston ring.

Background technology

Component of the piston ring as engine cardia, at the same be also vulnerable part piston ring consumption of lubricating oil is played Vital effect, however in recent years the research in terms of consumption of lubricating oil was reduced by being improved in terms of piston ring very Limited, China does a lot of work in terms of exploitation large-diameter, raising complete machine power in recent years, and is using poor quality fuel oil, drop Low oil consumption, the reliability for improving parts, raising service life and high pressure-charging etc. achieve remarkable effect, but compared to state Outer product：Highly enriched such as continuous in commission reliability, exhaust gas discharge meets increasingly severe emission regulation demands, comprehensive Economy, especially consumption of lubricating oil etc. still have larger gap, how to be improved conventional piston ring, to reduce oil Consumption, it is energy saving be worth we probe into.

Invention content

In order to reduce oil consumption, a kind of energy saving, novel piston ring of present invention proposition.

This novel piston ring, which is characterized in that including first of ring, second ring, third road ring and the 4th ring；Institute State first of ring thickness 6mm, thickness direction is provided with 45 ° of first angle on first of ring, two bevel edge of the first angle at a distance of 0.6 ~ 0.9mm；First 45 ° of angle left tilted surface top chamfering, 45 ° of the following chamfering of the first angle right tilted surface, circumference on first of ring outer wall Side and lower circumferential edge have radius for the fillet of 4mm, and three faces are coated with ceramic layers of chrome, chromium ceramic slice width 0.25 in first of ring outer circle ~ 0.4mm, first of ring outer circle are asymmetric bucket face structure；Second ring thickness 6mm is provided on second ring thickness direction One vertical mouth, first vertical 1.7 ~ 2.0mm of mouth width, circumferential edge falls 45 ° of chamferings on second ring inner wall, second ring outer wall with it is perpendicular For histogram at 2 ~ 3 ° of inclinations angle, third road ring is identical as second ring structure；There is annular groove on 4th ring inner wall, is installed in annular groove There is a helical supporting spring, there is a rod bolt in helical supporting spring tail portion, the 4th ring thickness 10mm, has the second of through-thickness vertical on the 4th ring Mouthful, second vertical 0.8 ~ 1mm of mouth width；First of ring, second ring, the internal diameter of third road ring and the 4th ring are identical；First Ring, second ring, the outer diameter of third road ring and the 4th ring are identical.

When in use, first of ring, second ring, third road ring and the 4th ring are combined in placing on piston.

Present invention has the advantages that relative to traditional 6 piston rings, consumption of lubricating oil is reached by original 0.8g/Kw.h 0.4-0.6g/Kw.h, average daily consumption of lubricating oil are reduced to 20Kg by original 40-50Kg, and oil-saving rate reaches 40%, and reduces production Cost, hardness meet HRB97-107, are less than 3 HRB units with loop hardness；Elasticity modulus：105000±15000N/mm²； Bending strength：More than 400N/mm2.
