Abstract
The utility model discloses a kind of doctor blade rings of internal-combustion engine piston ring compound oil ring, the a height of h of ring of the doctor blade ring, periphery are inclined bucket face, and two parts are respectively upper bucket face and lower bucket face up and down in bucket face, upper bucket face degree is 0.005~0.030mm, lower bucket face 0.000~0.010mm of degree.The utility model by the outer circle working face of doctor blade ring by being designed to inclined bucket face structure, and bucket face high point is biased to piston ring lower face, so that when doctor blade ring work uplink, realize the uniform cloth oil on casing wall in drum face, form oil film, promote lubrication, effectively reduces scuffing of cylinder bore, while reducing the abrasion of doctor blade ring；When doctor blade ring downlink, high point effective frizing in bucket face is simultaneously gone out, effective oil-control by keg surface current.During the work time, the vertex in bucket face is contacted with casing wall doctor blade ring always, and contact area is small, and oil ring elastic force is greatly lowered under the premise of ensureing oil ring face pressure, to reduce the frictional work loss of engine consumption on the piston ring, improves the power output of engine.
Description
Technical field
The utility model is related to piston ring technical field, the doctor blade ring of specifically a kind of internal-combustion engine piston ring compound oil ring.
Background technology
In Modern Engine design, realize that engine lightweight, low oil consumption, low emission have become Engine Industry design
Trend, key components and parts of the piston ring as engine, performance condition directly affects engine performance.Wherein in piston ring
The major function of oil ring is to adjust lubricating oil, and when work scrapes lubricating oil extra on cylinder wall, plays Controlling oil effect, property
Energy situation directly influences the consumption of lubricating oil and discharge capacity of engine, so to improve the oil-control ability of oil ring as far as possible.It is existing
It is mainly the frizing ability that oil ring is improved by higher oil ring face pressure to have oil ring, improves oil ring face pressure and mainly passes through raising
The tension of oil ring and the oil ring contact height of reduction are realized.However higher oil ring tension can increase the frictional work damage of piston ring
Consumption, to reduce the output of engine, while can also increase the abrasion of piston ring.And the contact height of oil ring is reduced, in grommet
In the oil ring combined with two panels doctor blade ring, referring to the ring height for reducing doctor blade ring, doctor blade ring is excessively thin to be designed there may be job insecurity,
Brittleness is big after surface treatment, leads to abscission ring of installing.This just needs to realize the oil-control ability for improving oil ring by other means.It is existing
The working face of doctor blade ring outer circle is nearly all semi arch structure, does not do and optimizes, scraping effect is poor.
Utility model content
Goal of the invention：In order to overcome the deficiencies in the prior art, the utility model to provide a kind of internal-combustion engine piston ring
The doctor blade ring of compound oil ring.
Technical solution：In order to solve the above technical problems, a kind of internal-combustion engine piston ring compound oil ring of the utility model is scraped
Loop, including grommet and doctor blade ring, a height of h of ring of doctor blade ring, periphery be inclined bucket face, bucket face up and down two parts be respectively on
Bucket face and lower bucket face, upper bucket face degree are 0.005~0.030mm, lower bucket face 0.000~0.010mm of degree.
Wherein, doctor blade ring bucket face high point is located at (0.25~0.4) × h height of doctor blade ring.
Wherein, the bucket face starting position of doctor blade ring is located at (0.15~0.3) × h height of doctor blade ring.
Wherein, the bucket face end position of doctor blade ring is located at (0.65~0.8) × h height of doctor blade ring.
Wherein, doctor blade ring periphery is one or more combinations in chromium plating, nitridation, CCC, CDC, PVD, DLC.
Advantageous effect：A kind of internal-combustion engine piston ring compound oil ring of the utility model, has the advantages that：
The utility model by the outer circle working face of doctor blade ring by being designed to inclined bucket face structure, and bucket face high point is biased to live
Plug ring lower face so that when doctor blade ring work uplink, the uniform cloth oil on casing wall is realized in drum face, is formed oil film, is promoted to lubricate,
It is effective to reduce scuffing of cylinder bore, while reducing the abrasion of doctor blade ring；When doctor blade ring downlink, high point effective frizing in bucket face simultaneously passes through keg face
Outflow, effective oil-control.During the work time, the vertex in bucket face is contacted with casing wall doctor blade ring always, and contact area is small, is ensureing oil
Oil ring elastic force is greatly lowered under the premise of anchor ring pressure, to reduce the frictional work loss of engine consumption on the piston ring, carries
The power output of high engine；Ring body need not design excessively thin simultaneously, ensure stability when doctor blade ring work, avoid being surface-treated
Breakage problem when brittleness causes to install greatly afterwards.

Fig. 1 is the front view of compound oil ring；
Fig. 2 is A-A in Fig. 1 to sectional view；
Fig. 3 is enlarged drawing at the I in Fig. 2.
Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings.
As shown in Fig. 2-Fig. 3, a kind of doctor blade ring of internal-combustion engine piston ring compound oil ring of the utility model, the doctor blade ring 1
The a height of h of ring, periphery is inclined bucket face, and two parts are respectively upper bucket face and lower bucket face up and down in bucket face, and upper bucket face degree is t3：
0.005~0.030mm, lower bucket face degree t2：0.000~0.010mm.The bucket face high point h26 of doctor blade ring 1 is located at the doctor blade ring
At (0.25~0.4) × h height, the bucket face starting position h25 of doctor blade ring 1 is located at (0.15~0.3) × h height of the doctor blade ring
Place, the bucket face end position h27 of doctor blade ring are located at (0.65~0.8) × h height of doctor blade ring.Doctor blade ring periphery is plating
One kind in chromium, nitridation, CCC, CDC, PVD, DLC.To further increase doctor blade ring wearability, doctor blade ring periphery can be plated
One or more combinations in the surface treatments such as chromium, nitridation, CCC, CDC, PVD, DLC.
The doctor blade ring of the utility model can be applied to compound oil ring, and compound oil ring may include doctor blade ring 1 and grommet 2, such as Fig. 1
Shown in Fig. 2.
The utility model doctor blade ring basis material is steel material, and the inclined bucket face shape of periphery can pass through shaped-steel strip
