Description
Technical field
The utility model relates to dynamic power machine parts technical fields, and in particular to a kind of oil ring for piston ring.
Background technique
Piston ring is one of key components and parts of internal combustion engine, and with the development of modern automobile industry, engine is in discharge, combustion
Oil consumption and service life etc. require higher and higher.There are two types of piston ring for combustion engines, is oil ring one is compression ring another kind,
Wherein oil ring plays Controlling oil effect.
General piston ring of diesel engine oil ring is typically designed to two sides rectangular section (and symmetrical double scraping oil blade), piston ring with
Piston groove is rectangular surfaces cooperation, and piston ring slides in the cylinder, due to the swing of piston crown, cylinder deformation and piston ring itself
The factors such as trembling, move it radially.The fit clearance of rectangular section piston ring and piston ring groove in this case
It is constant, bond piston ring and annular groove, especially this phenomenon of heavy duty diesel engine is more serious.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of having for piston ring of diesel engine
The oil ring of the advantages that fuel-economizing, good anti stick effect.
To solve the above problems, the utility model provides the following technical solutions:
A kind of oil ring for piston ring, including oil ring body and U-shaped support spring, oil ring body both ends of the surface are equipped with lozenges, oil ring
External disc is equipped with double scrap blades, and circle is equipped with dovetail groove in oil ring body, and U-shaped support spring is equipped in dovetail groove.
Preferably, double scrap blades are symmetricly set on the external disc of oil ring.
Preferably, dovetail groove inner surface is coated with layers of chrome.
Preferably, the key groove of lozenges is 7.4 °~7.8 °.
Preferably, scrap blade lateral surface and the angle of end face outer surface are 30-45 °；Table in scrap blade medial surface and end face
20-35 ° of the angle in face.
Preferably, the angle that two inclined-planes of the dovetail groove are formed is 20-35 °.
Preferably, U-shaped support spring is pressed into U-shaped for heat-resisting alloy guiding principle silk, after circle is made, is placed on circle in oil ring body
In dovetail groove.
The utility model has the following beneficial effects:
Compared with prior art, the utility model effectively prevent piston ring to bond with annular groove stuck, effectively increases diesel oil
Machine economy and Service Life of Piston Ring guarantee that oil ring and casing wall have good coating performance, have good oil-control and scrape oiliness
Can, so that fuel oil is fully burned, long-time stable keeps the low consumption of machine oil, especially suitable for large diesel engine piston
Ring.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is this
Some embodiments of utility model, for those of ordinary skill in the art, without creative efforts, also
Other drawings may be obtained according to these drawings without any creative labor.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the Section A-A structural schematic diagram in Fig. 1；
Fig. 3 is the structural schematic diagram of U-shaped support spring；
Fig. 4 is the unfolded state schematic diagram of U-shaped support spring.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments, based on the implementation in the utility model
Example, those of ordinary skill in the art's every other embodiment obtained without making creative work, all belongs to
In the range of the utility model protection.
As shown in Figs 1-4, a kind of oil ring for piston ring, including oil ring body 1 and U-shaped support spring 2,1 both ends of the surface of oil ring body
Equipped with upper lozenges 5 and lower lozenges 6, the key groove of lozenges is 7.4 °~7.8 °.1 periphery of oil ring body, which is symmetrically arranged with, to be scraped
The angle of oily sword 3 and lower scrap blade 4, scrap blade lateral surface and end face outer surface is 30-45 °；In scrap blade medial surface and end face
20-35 ° of the angle on surface.Circle is equipped with dovetail groove in oil ring body, and dovetail groove has ramp 7 and lower inclined plane 8,7 He of ramp
The angle that lower inclined plane 8 is formed is 20-35 °.Dovetail groove inner surface is coated with layers of chrome.U-shaped support spring 2 is equipped in dovetail groove.U-shaped support spring
2 are pressed into U-shaped for heat-resisting alloy guiding principle silk, after circle is made, are placed in the dovetail groove of 1 inner circle of oil ring body.
The utility model on oil ring body by being arranged double-wedge face, and piston ring slides in the cylinder, due to piston crown
Swing, the factors such as trembling of cylinder deformation and piston ring itself move it radially.Trapezoid cross section in this case
The cooperation axial gap of piston ring and piston ring groove changes in a certain range and (becomes larger or become smaller), and this movement passes through wedge
Shape active force, by annular groove carbon distribution squeeze out (substance for having abolished any accumulation of residues of combustion), thus effectively prevent piston ring with
Annular groove bonding is stuck, and scuffing of cylinder bore occurs, engine fuel economy and Service Life of Piston Ring are effectively increased, especially suitable for heavy bavin
Oil machine piston ring.
In addition, the circle described in the utility model in oil ring body is equipped with dovetail groove, chromium plating in dovetail groove is equipped in dovetail groove
U support spring.This structure oil ring body is flexible, wearability is good, has very big adaptability to abrasion, the cylinder for losing circle, deforming, guarantees
Oil ring and casing wall have good coating performance, have good oil-control and frizing performance, fuel oil is made to be fully burned, for a long time
Stablize the low consumption for keeping machine oil.
