Description
Technical field
The present invention relates to turbo-charger technical field, especially a kind of whirlpool end oil baffle structure for turbocharger.
Background technique
The main function of turbocharger is to improve air input of engine by air to increase maximum power and torque, is had simultaneously
Engine fuel consumption is reduced, exhaust gas discharge is reduced, improve engine power and restores the effect of plateau power.Turbocharger
For high-speed rotating machine, it is made of systems such as bearing arrangement and sealing systems.
Bearing arrangement is made of armature spindle, floating bearing, bearing body.Supercharger rotor axis does high speed rotation, in armature spindle
Between floating bearing, a thin layer of oil film is respectively formed between bearing body and floating bearing, armature spindle exactly leans on this two layers oil
Film supports, and keeps balance, is just able to work normally under per minute ten tens of thousands of turns of revolving speed.
Sealing system is made of parts such as sealing rings, can be by the exhaust gas chamber of the oil pocket of bearing body and turbine box by sealing ring
It separates, limitation machine oil flows into the exhaust gas chamber of turbine box.However, when sealing system sealing effect is deteriorated or fails or designs bad etc.
When, the oil mass at bearing body oil pocket sealing ring is more, and oil pressure height can reduce the sealing function of sealing ring or lose sealing effect, in this way
Cause lubricating oil to flow into the exhaust gas chamber pollution whole gas extraction system of turbine box, exhaust system is caused to fail, so that booster is dynamic flat
Weighing apparatus destroys, booster rubs shell destruction, causes that engine oil pressure is relatively low, lack of lubrication, or even causes engine scuffing.
The existing whirlpool end oil baffle structure of turbocharger enters axis by the oil inlet 1a of bearing body 1 referring to Fig. 1, lubricating oil
The gap between the gap between body 1 and floating bearing 6 and bearing body 1 and the axis of turbine rotor 4 is held, a part of lubricating oil is then
Enter the position disc 4-1 of turbine rotor 4 by the gap between bearing body 1 and the big axis 4-2 of turbine rotor 4.Work as turbine
When rotor 4 rotates, a part of lubricating oil therein is dumped at the cavity A of bearing body 1, it is understood that there may be in addition one is a small amount of or micro
Lubricating oil is carried on the back at B by the wheel that sealing ring 3 enters turbine rotor 4, and then back drains at the waste gas outlet C of turbine box 2, most heel row
Exhaust system.
Summary of the invention
To solve the above problems existing in the prior art, the present invention provides a kind of whirlpool ends for turbocharger to keep off oil
Structure reduces lubricating oil and alters to turbine box exhaust gas chamber to reduce, reduce the engine oil pressure and oil flow rate at sealing ring.
This practical invention is realized using following technical scheme:
A kind of whirlpool end oil baffle structure for turbocharger, including turbine rotor and bearing body, the turbine rotor tool
There is a turbine end axis, which is characterized in that be provided with a disc on the turbine end axis.It can will moisten when turbine rotor rotation
Lubricating oil is radially thrown away, and reduces and reduce the engine oil pressure and oil flow rate that flow at sealing ring.
In a preferred embodiment of the invention, the position of the nearly turbine end axis of the bearing body is provided with gear oil
Wall is flowed at sealing ring with stopping and reducing the lubricating oil thrown away.
In a preferred embodiment of the invention, the inner ring surface of the oil protection wall and the outer ring surface of the disc pass through
Oil film contact.
In a preferred embodiment of the invention, in the side of the oil protection wall and the disc towards floating bearing
It is provided with and gets rid of oil pocket, the lubricating oil that disc is thrown away is blocked by oil protection wall and got rid of at oil pocket, then flow to increasing under the effect of gravity
Depressor oil return line can reach lubricating oil is prevented to alter into turbine box and exhaust system in this way.
Due to using technical solution as above, compared with the prior art, the invention has the following advantages:
1, increase by one disc of design on the turbine end axis of turbine rotor, lubricating oil can radially be thrown away, reduce, reduce
Flow to the engine oil pressure and oil flow rate at sealing ring.
2, an oil protection wall is designed on the nearly turbine end end of bearing body, can stops and reduce the lubrication that new design disc is thrown away
Oil stream is altered to reduce lubricating oil to turbine box exhaust gas chamber at sealing ring.
3, in booster turbine end Combination Design disc and oil protection wall, composition gets rid of oil pocket, can reach better seal effect
Fruit.
Detailed description of the invention
Fig. 1 is the existing whirlpool end oil baffle structure schematic diagram of turbocharger.
Fig. 2 is structural schematic diagram of the present invention for the whirlpool end oil baffle structure of turbocharger.
Fig. 3 is enlarged diagram at the I of Fig. 2.
Specific embodiment
Below according to the drawings and specific embodiments, invention is further described in detail.
Referring to figs. 2 and 3, a kind of whirlpool end oil baffle structure for turbocharger shown in figure, in turbine rotor 4
Turbine end axis 4-3 on increase design one disc 4-4, when turbine rotor 4 rotate when lubricating oil can radially be thrown away, reduce and
Reduce the engine oil pressure and oil flow rate flowed at sealing ring 3.In addition in the Position Design one of the nearly turbine end axis 4-3 of bearing body 1
The inner ring surface of oil protection wall 1-1, oil protection wall 1-1 contacted with the outer ring surface of disc 4-4 by oil film, can stop and reduce to throw away
Lubricating oil flows at sealing ring 3.By Combination Design, set in disc 4-3 and oil protection wall 1-1 towards the side of floating bearing 6
It is equipped with and gets rid of oil pocket D, the lubricating oil that disc 4-3 is thrown away is blocked by oil protection wall 1-1 and got rid of at oil pocket D, then under the effect of gravity
It is flow to pressurizer oil pipeline, can reach lubricating oil is prevented to alter into turbine box 2 and exhaust system in this way.
