Abstract
The invention discloses a piston ring with a super-wear-resistant side face. The piston ring comprises a piston ring body and a diamond-like coating on the side face of the ring body. By arranging the thin diamond-like coating on the side face of the piston ring, the wear resistance of the side face of the piston ring is improved, the impact of the side face of the piston ring on a ring groove is reduced, the problem of aluminum adhesiveness of the side face of the piston ring is solved, and the piston ring groove is improved. The piston ring is beneficial for reducing air leakage of an engine and especially suitable for high-detonation-pressure and high-heat-load engines.
Description
One, technical field:
The present invention relates to a kind of piston ring, be specifically related to a kind of side super abrasive piston ring, belong to piston ring surface processing technology field.
Two, background technique:
In order to realize the energy-saving and cost-reducing of motor further, high pressure of explosion, high heat load motor are by more designs and employing.Engine cylinder internal pressure becomes large, and percussion power when can exacerbate the upper and lower motion of piston ring axis and between annular groove, easily causes the wearing and tearing of piston ring side abrasion and annular groove.In addition, high heat load motor easily occurs, between piston ring side and annular groove, aluminium adherent phenomenon occurs.Piston ring side and piston ring groove all will increase leakage path after occurring wearing and tearing or aluminium adhesion occurring, and cause the air leakage of motor to increase, affect the power per liter of motor.So need to solve piston ring side abrasion and ring groove side surface wear and piston ring side aluminium adhesion problems for high detonation pressure, high heat load motor.
Three, summary of the invention:
Task of the present invention there is provided a kind of side super abrasive piston ring, effectively will solve that piston ring side abrasion is large, the problems such as aluminium adhesion occur in groove wear large and piston ring side.
In order to solve the problem, the technological scheme that piston ring of the present invention adopts is such: it comprises piston ring ring body, and on the side of ring body, apply the thin diamond-like coating of one deck.Described diamond-like coating thickness evenness is good, and its thickness range controls at 0.001 ~ 0.003mm.
Diamond-like coating has extremely low friction factor and superpower abrasion resistance properties, minimum to opponent's material aggressiveness of coupling.So after diamond-like coating being coated in the side of piston ring, substantially increase the side wear-resisting property of piston ring on the one hand, protect annular groove well on the other hand, reduce the wearing and tearing of piston ring groove.In addition, because diamond-like coating has extremely low friction factor, will effectively prevent after piston ring groove high temperature generation aluminium melts, between piston ring side, aluminium adherent phenomenon occur.
After using inventive piston ring, the piston ring side abrasion of motor and the wear extent of piston ring groove minimum, and decrease piston ring side aluminium adherent phenomenon, HP, hp/litre is guaranteed, what realize truly is energy-saving and cost-reducing.
The piston ring large for downside wear extent applies one deck diamond-like coating in the downside of piston ring, for the piston ring that upper and lower side abrasion amount is all larger, can apply diamond-like coating to the upper and lower aspect of piston ring simultaneously.
Four, accompanying drawing explanation
Fig. 1 is schematic cross-section of the present invention;
Fig. 2 is another schematic cross-section of the present invention.
Five, embodiment
See Fig. 1, inventive piston ring comprises the diamond-like coating 2 that piston ring ring body 1 and piston ring ring body 1 downside are provided with, and the periphery of piston ring can carry out the hard processing layer such as nitrogenize, chromium plating, CKS, PVD, DLC;
See Fig. 2, inventive piston ring comprises the diamond-like coating 2 that piston ring ring body 1 and the upper and lower side of piston ring ring body 1 are all provided with, and the periphery of piston ring can carry out the hard processing layer such as nitrogenize, chromium plating, CKS, PVD, DLC.
Piston ring side of the present invention diamond-like coating 2 adopts physical vapor deposition or chemical vapor deposition mode to generate by special installation way, and layer thickness uniformity is good, and general control is within the scope of 0.001 ~ 0.003mm.
Claims (1)
1. a side super abrasive piston ring, comprise piston ring ring body, it is characterized in that: the downside of described piston ring ring body (1) or upper and lower side are provided with the thin diamond-like coating of one deck (2) simultaneously, and the thickness range of diamond-like coating (2) is: 0.001 ~ 0.003mm.
