Description

A kind of novel piston ring

Technical field

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

Background technology

Piston ring as the component of electromotor cardia, is also that the piston ring of vulnerable part plays to consumption of lubricating oil simultaneously Vital effect, but to reduce research in terms of consumption of lubricating oil very by improving in terms of piston ring in the last few years Limited, China does a lot of work in terms of exploitation large-diameter, the whole acc power of raising in recent years, and is using poor quality fuel oil, fall Low oil consumption, the reliability improving parts, the raising aspect such as service life and high pressure-charging achieve remarkable effect, but compared to state Outer product：As continuous in commission reliability, highly enriched, waste gas discharge meets increasingly severe emission regulation demands, comprehensive The aspects such as economy, especially consumption of lubricating oil still have larger gap, how to improve conventional piston ring, thus reducing oil Consumption, energy saving are worth us to probe into.

Content of the invention

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

This novel piston ring is it is characterised in that include first ring, second ring, the 3rd road ring and the 4th road ring；Institute State first ring thickness 6mm, on described first ring, thickness direction has 45 ° of first angle, the first angle two hypotenuse 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 ring outer wall Side and lower circumferential edge have a fillet that radius is 4mm, and cylindrical upper three faces of first ring are coated with ceramic layers of chrome, chromium ceramic slice width 0.25 ~ 0.4mm, first ring cylindrical for asymmetric bucket face structure；Second ring thickness 6mm, has the on second ring thickness direction One vertical mouth, the wide 1.7 ~ 2.0mm of the first vertical mouth, on second ring inwall, circumferential edge falls 45 ° of chamferings, second ring outer wall with perpendicular To becoming 2 ~ 3 ° of inclinations angle, on second ring outer wall, circumferential edge has 45 ° of chamferings to Nogata；3rd road ring is identical with second ring structure； There is annular groove on 4th road ring inwall, helical supporting spring is installed in annular groove, helical supporting spring afterbody has rod bolt, the 4th road ring thickness 10mm, Second vertical mouth of through-thickness had on the 4th road ring, the wide 0.8 ~ 1mm of the second vertical mouth；First ring, second ring, the 3rd The internal diameter of road ring and the 4th road ring is identical；First ring, second ring, the 3rd road ring and the 4th road ring external diameter identical.

When using, first ring, second ring, the 3rd road ring and the 4th road ring group are closed in placing on piston.

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