Description
Technical field
The invention belongs to internal combustion engine turbocharging technical field, and in particular to one kind is calmed the anger for ball bearing turbine supercharger
The sealing structure of generator terminal.
Background technology
The purpose of turbocharging technology is to improve the fuel economy of engine, power performance, can reduce engine emission,
Performance on Plateau that is Engine Downsizing, and compensating vehicular engine can be made.Turbocharger not consumption of engine it is effective
Power, the exhaust energy that its turbine discharges engine reclaim, and drive coaxial compressor pressurised fresh air, so as to increase hair
The air inflow of motivation, increase the power density of engine.
The bearing of turbocharger experienced the developing stage of sliding bearing, floating bearing and ball bearing, and ball bearing is to increase
The newest bearing arrangement of depressor.Compared to the booster of application floating bearing, booster can simplify supercharging after using ball bearing
Device structure, thrust bearing, thrust housing and gear oil that conventional float bearing booster is possessed are fitted without on ball bearing booster
Plate.
The one-piece corner connection that ball bearing booster is installed by it, which touches ball bearing, can balance the axial force of booster.Ball
The generator terminal of calming the anger of bearing booster is also equipped with pressure side seal ring structure and is used to separate compressor and intermediate oil pocket, still, by
There is no special oil baffle in ball bearing booster, and pressure side sealing ring junction seal and oil-blocking action on ball bearing booster
It is limited, this just needs to focus on devising for sealing axle sleeve and oil pocket cover plate, it is necessary to matching somebody with somebody sealing axle sleeve and oil pocket cover plate
Conjunction face is designed to be able to gear oil, has the function that to completely cut off lubricating oil in intermediate oil pocket.
At present, ball bearing research and application do not carry out on a large scale also, the design and research of its sealing system do not have
In depth carry out.
The content of the invention
The present invention provides a kind of sealing structure for generator terminal of being calmed the anger for ball bearing turbine supercharger, has isolation turbocharging
The effect of lubricating oil in the intermediate oil pocket of device.
Technical scheme is as follows：
A kind of sealing structure for generator terminal of being calmed the anger for ball bearing turbine supercharger, including sealing axle sleeve, oil pocket cover plate and pressure
Sealing ring is held, closure gasket groove and radial direction boss are provided with the sealing axle sleeve, the radial direction boss is provided with bearing end axial direction
Chimb and pressure side axial direction chimb, bearing end axial direction chimb form bearing end groove with radial direction boss, and the pressure side is axially convex
Side forms pressure side groove with radial direction boss；The oil pocket cover plate is provided with cover plate axial boss and edge lug boss, the plate shaft
Cover plate axial notch is collectively formed to the radial component of boss and edge lug boss and oil pocket cover plate, is set in the cover plate axial boss
There is cover plate radial direction chimb, the cover plate radial direction chimb and the radial component of the cover plate axial boss and oil pocket cover plate collectively form
Cover plate radial groove；The internal diameter of pressure side axial direction chimb is more than the external diameter of the cover plate radial direction chimb, the cover plate radial convex
While being placed in the pressure side groove, the pressure side sealing ring is provided between sealing axle sleeve and the oil pocket cover plate.The sealing
Structure setting is on the armature spindle of turbocharger, between compressor impeller and ball bearing.
Beneficial effects of the present invention are：Radial direction boss, pressure side axial direction chimb and the bearing end axial direction chimb of sealing axle sleeve, with
And the cover plate radial direction chimb of oil pocket cover plate collectively constitutes oil baffle structure with cover plate axial boss so that flows to and presses from intermediate oil pocket
The lubricating oil at mechanism of qi end is blocked in intermediate one end, it is impossible to smoothly enters pressure side sealing ring position, lubricating oil passes through seal shaft
The bearing end groove of set and the cover plate axial notch of oil pocket cover plate flow to the oil return opening of intermediate with cover plate radial groove.This gear oil
Structure coordinates pressure side seal ring structure again, can effectively obstruct lubricating oil and enter generator terminal of calming the anger.
