Abstract
The utility model relates to a turbine pressure booster preventing oil leakage, which comprises a gas pressing wheel, a gas pressing casing, a middle body, a turbine casing, a turbine and a rotation shaft, wherein the gas pressing wheel and the gas pressing casing are arranged on a gas pressing end; the turbine casing and the turbine are arranged on a gas outlet end; one end of the rotation shaft near the gas pressing wheel is provided with a thrust piece, an oil baffling plate and a gas sealing plate; a shaft sealing is arranged between the rotation shaft and the gas sealing plate; and the middle body provides a lubricant channel. The turbine pressure booster preventing oil leakage is characterized in that the middle body also provides a through hole from the outside of the middle body to the gas sealing plate, then air or waste gas exhausted by an engine goes between the oil baffling plate and the gas sealing plate by the through hole, and then the waste gas or the air goes into the gas pressing end from the shaft sealing when positive pressure is generated on the gas pressing end.
Description
Technical field
The utility model relates to a kind of turbosupercharger.
Background technique
Turbosupercharger is widely used in automobile, generator set, boats and ships and engineering machinery, it is that the exhaust energy that utilizes motor to discharge drives turbine, the wheel of calming the anger that promptly drives turbine compresses the motivation of setting out with more air, thereby more combustion gas is fully burnt, improve engine power widely, and reduce the discharging of harmful substance.
When using motor in the plateau section, because rarefaction of air, the engine power of natural aspiration will descend, and motor is pressed as adopting turbine to increase, and then can remedy decline power.Supercharger speed is very high, and generally at 120,000-170,000 rev/mins, pressurized machine is by oil lubricating.
As shown in Figure 1, existing turbosupercharger comprises the wheel 10 of calming the anger, the shell 11 of calming the anger, intermediate 13, volute 14, turbine 15, rotating shaft 12 and floating bearing 16, thrust plate 19, oil baffle 17, seal ring 20, axle envelope 21 and sealing gland plate 18.The waste gas of motor is gone out from volute 14, drives turbine 15 and rotates, and the outer end of turbine 15 is the air outlet 25 of turbosupercharger, and turbine 15 drives the wheel 10 of calming the anger that is in air inlet 22 by rotating shaft 12 again, and the wheel 10 of calming the anger is pressed into the shell 11 of calming the anger with air.Rotating shaft 12 is arranged on the intermediate 13 rotationally, and the lubricant oil that offers rotating shaft 12 enters from filler opening 24, and lubricant oil is through being back to fuel tank behind the floating bearing everywhere from return opening 23.For preventing that lubricant oil from entering the end of calming the anger, be provided with oil baffle 17 and axle envelope 21, axle envelope 21 comprises seal ring 20.Thrust plate 19 mainly plays the axially locating effect.
There is such shortcoming in aforementioned turbosupercharger: for example in the using process on the plateau, the constantly lubricated and cooled interior parts of machine oil in the intermediate, if pressurized machine air inflow in the course of the work is not enough, air pipe gas leakage or motor belt speed overlong time, the end of calming the anger will produce negative pressure, and when the wheel back side of calming the anger produced certain negative pressure, the lubricant oil (machine oil) in the intermediate was easy to be drawn out of and, will produce oil leakage phenomenon, leakage of oil is in the sealing gland plate, a seal ring of sealing up spills.
The model utility content
The purpose of this utility model is to provide a kind of improved turbosupercharger, produces negative pressure and causes oil leakage phenomenon with the end of calming the anger that prevents pressurized machine.
In order to realize described purpose, the turbosupercharger of anti-leakage of oil of the present utility model, the end of calming the anger that comprises the calm the anger wheel and the shell place of calming the anger, intermediate, the outlet side at volute and turbine place and rotating shaft, rotating shaft is provided with thrust plate near an end of the wheel of calming the anger, the gentle shrouding of oil baffle, the axle envelope is set between the gentle shrouding of rotating shaft, intermediate provides grease channel, be characterized in, intermediate also provides outside from intermediate to the vent the sealing gland plate, so that the waste gas that air or motor are discharged enters between the gentle shrouding of oil baffle by this vent, and then described waste gas or air enter into the end of calming the anger from the axle envelope when producing negative pressure at the end place of calming the anger.
The beneficial effects of the utility model are: because described vent extends through the sealing gland plate from the outside of intermediate, when the end of calming the anger of turbosupercharger produces negative pressure, the waste gas that discharge the outlet side of turbosupercharger, perhaps ambient air (be generally filtration after air) will enter into this end of calming the anger from described vent, so just prevented that the lubricant oil (machine oil) in the intermediate from entering into the end of calming the anger, and then avoided oil leakage phenomenon.
Description of drawings
Fig. 1 is the structural drawing of existing a kind of turbosupercharger.
Fig. 2 is an an embodiment's of the present utility model structural drawing.
Embodiment
As shown in Figure 1, an embodiment of the present utility model comprises the wheel 30 of calming the anger, the shell 31 of calming the anger, intermediate 33, volute 34, turbine 35, rotating shaft 32 and floating bearing 36, thrust plate 39, oil baffle 37, seal ring 40, axle envelope 41 and sealing gland plate 38.The waste gas of motor is gone out from volute 34, drives turbine 35 and rotates, and the outer end of turbine 35 is the air outlet 45 of turbosupercharger, and turbine 35 drives the wheel 30 of calming the anger that is in air inlet 42 by rotating shaft 32 again, and the wheel 30 of calming the anger is pressed into the shell 31 of calming the anger with air.Rotating shaft 32 is arranged on the intermediate 33 rotationally, and the lubricant oil that offers rotating shaft 32 enters from filler opening 44, and lubricant oil is through being back to oil sump behind the floating bearing everywhere from return opening 43.For preventing that lubricant oil from entering the end of calming the anger, be provided with oil baffle 37 and axle envelope 41, axle envelope 41 comprises seal ring 40.Sealing gland plate 38 mainly plays the wind-guiding effect.Thrust plate 39 mainly plays the axially locating effect.
Be with existing turbosupercharger difference, be provided with vent 100 from the outside of intermediate 33 to the sealing gland plate 38, the waste gas or the process filtered air that so just can utilize motor to discharge enter between the oil baffle 37 gentle shroudings (dish of calming the anger in other words) 38 by vent 100, pressurized machine is calmed the anger in the end, when the end of calming the anger of pressurized machine produces certain negative pressure, can constantly release from the seal ring 40 of axle envelope 41 waste gas or through filtered air, and can lubricant oil directly not extracted out, so just avoided oil leakage phenomenon, and then avoided the pollution of leakage of oil environment.
