Description

A kind of be used for vehicle supercharger calm the anger the end oil leakage preventing apparatus
Technical field
The utility model relates to a kind of oil leakage preventing apparatus that is used for vehicle supercharger, relates in particular to a kind of oil leakage preventing apparatus that vehicle supercharger is calmed the anger and held that is used for.
Background technique
Along with the use of domestic supercharged diesel engine on automobile, increasing user finds: after the normal use of a period of time, the diesel engine emergent power descends, and over-emitting black exhaust is arranged, emit the phenomenon of blue smoke, and the engine lubrication consumption of lubricating oil increases greatly, this is domestic supercharged diesel engine automobile, particularly the ubiquitous problem of city carrier and passenger vehicle.The main cause that causes this phenomenon is in the filter cleaner obstruction, particularly under diesel engine idling situation, the gas quantity that enters the pressurized machine fuel gas inlet is few, supercharger speed is in 10000 to 20000rpm low operating mode operations, the compressor air inlet machine quantity not sufficient produces about 1KPa degree of vacuum, cylinder of diesel engine also will be calmed the anger from slow-speed of revolution pressurized machine, and to bring out gas port air-breathing, causes pressurized machine calm the anger end generation-5KPa even higher degree of vacuum; In addition, 100 ℃ of the Gao Shikeda of lubricating oil temperature, viscosity reduces, under this disadvantageous mal-condition, the lubricating oil pressurized by sucking-off by force, enters cylinder of diesel engine internal combustion through blower outlet by sealing part, has a strong impact on the working life of cylinder of diesel engine.
At present, when the motor car engine on-load runs well, the pressurized machine that can seal calm the anger the end oil leakage preventing apparatus comprise a big envelope, dividing plate, oil baffle, the pressure side seal ring, its being connected to of end of calming the anger in pressurized machine: the two ends of axle big envelope contact with compression impellor with Thrust ring respectively, and are fixed on the turbine shaft by armature nut; Dividing plate is fixed in the cartridge housing by back-up ring, and its other end is fitted and is pressed on the end face of thrust-bearing, and the O RunddichtringO is set between dividing plate and the cartridge housing; The pressure side seal ring is contained in the seal groove of a big envelope, relies on its elasticity tension and dividing plate endoporus step surface to fit; The middle part of oil baffle is enclosed within on the big envelope, and its cylindrical planar section is fixed between the end face step surface and thrust-bearing of dividing plate.The purpose of this structural design is to prevent leakage of oil: oil baffle is between boss face bathtub construction and the thrust-bearing end face, between the dividing plate inner chamber and the oil baffle back side, forms the twice oil pocket respectively, and the oil back chamber volume is increased, and reduces the pressure of lubricating oil; But the arc oil back chamber shape that the boss plane of oil baffle and dividing plate inner chamber are provided with in this structure, all make the oil return on oil pocket top constantly flow directly on the big envelope and dividing plate endoporus place along outer wall by deadweight, and certain accumulation arranged, therefore lubricating oil under the situation of negative pressure is being arranged easily from the leakage that is tightly connected between the seal groove of axle big envelope, pressure side seal ring, the dividing plate endoporus step surface.
Summary of the invention
It is a kind of when the motor car engine idle running that the purpose of this utility model is to provide, good sealing effect be used for vehicle supercharger calm the anger the end oil leakage preventing apparatus.
The purpose of this utility model is achieved in that a kind of oil leakage preventing apparatus that vehicle supercharger is calmed the anger and held that is used for, comprise a big envelope, dividing plate, oil baffle, the pressure side seal ring, wherein said pressure side seal ring is contained in the seal groove of described axle big envelope, described pressure side seal ring relies on elasticity tension and described dividing plate endoporus step surface to fit, the middle part of described oil baffle is enclosed within on the described axle big envelope, its cylindrical planar section cooperates with the end face step surface of described dividing plate, it is characterized in that: be provided with on the radial circumference of described axle big envelope and get rid of oil groove.Get rid of oil groove during the pressurized machine running and get rid of oil and form oil seal, do not allow lubricating oil accumulate on the big envelope and dividing plate endoporus place, and reduce amount of flow to the end of calming the anger.
The radial circumference of above-mentioned axle big envelope is provided with two and gets rid of oil groove; One of them gets rid of oil groove and is arranged on and the corresponding position of described oil baffle, and its width is greater than the thickness of described oil baffle; Another gets rid of oil groove and is arranged near described dividing plate endoporus place.
The annular oil holding slot of aforementioned barriers inboard is formed by connecting by water conservancy diversion inclined-plane, deep gouge vertical plane, arc shaped hook groove from outside to inside successively.During near the getting rid of oil groove and get rid of oil of described dividing plate endoporus place, the long-pending oil of dividing plate inside upper part flows down fast and enters the arc shaped hook groove through water conservancy diversion inclined-plane, deep gouge vertical plane when above-mentioned, flow down from arc shaped hook groove middle part again, and do not flow through dividing plate endoporus and axle big envelope place.
Annular arc surface to described dividing plate one side evagination is set on the convex flat surface of above-mentioned oil baffle, and the position of the inside circumference of its circular arc is positioned at the position of adjacent described axle big envelope end face circumference.When the getting rid of oil groove and get rid of oil of the corresponding position of above-mentioned and described oil baffle, the annular arc surface of the evagination of oil baffle will get rid of the counter annular oil holding slot of throwing the aforementioned barriers inboard of oil and flow down, and the gap between oil baffle and the axle big envelope interior edge face makes and gets rid of oil and form oil seal, to reduce the inflow of lubricating oil.
The utility model is provided with on the axle big envelope and gets rid of oil groove and get rid of oil and form oil seal, and carry out dual oil removal and reduce oil pressure by the annular arc surface of the evagination of the annular oil holding slot of dividing plate, oil baffle, make the least possible seal groove place that penetrates into a big envelope of lubricating oil, therefore when the motor car engine idle running, still have good sealing effect at the vehicle supercharger end of calming the anger, and it is simple in structure.
