Abstract

The utility model relates to an oil-sealing mechanism for turbocharger combination, in particular to a device for improving oil leakage resistance of the compressor end of the turbocharger combination, pertaining to the technology field of mechanical oil sealing. An oil baffle is arranged on a gas seal plate, a sealing ring is positioned on a shaft seal and presses the inner hole of the gas seal plate and the oil baffle is arranged on the gas seal plate. The shaft seal is provided with holes and the gas seal plate with a ring groove. The utility model with simple, compact and reasonable structure enlarges oil return channel of lubricating oil flowed from a thrust bearing through the adding of the oil baffle and the improvement of the gas seal plate, which ensures a smooth oil return; meanwhile, the barrier action of the oil baffle prevents as possible the lubricating oil from entering into a sealing system and minimizes; the oil leakage resistance is obviously improved and the oil leakage of the turbocharger is improved; the production of the turbocharger has no difficulty, and the turbocharger can protect the environment, save lubricating oil and reduce the complaint from customers about oil leakage.

Description

The oil seal structure of turbosupercharger
Technical field
The utility model relates to a kind of oil seal structure of turbosupercharger, specifically is used to improve the anti-leakage of oil ability of turbocharger air compressor end, belongs to machinery oil encapsulation technique field.
Background technique
Turbosupercharger is the blade mechanism of high speed rotating, and it is very important accessory on the internal-combustion engine.During the pressurized machine operation, in the main oil gallery of internal-combustion engine, lubricant oil is introduced pressurized machine, floating bearing and thrust bearing are lubricated.Because the rotating speed of turbosupercharger is up to tens0000 rev/mins, even hundreds of thousands rev/min, so oil sealing need adopt special structure.
At present, radial-flow turbocharger mainly is to adopt seal ring structure and other auxiliary devices, carries out the sealing of gas and lubricant oil.The oil seal structure of pressurized machine is various informative, as the axle envelope that seal ring is contained in, have with holes, have not with holes; Seal ring have one ring, also two road rings are arranged; The employing that has axle envelope with holes is just without oil baffle; And adopt axle envelope not with holes, adopt oil baffle mostly simultaneously.The fault of turbosupercharger leakage of oil under some Environmental Conditions, can take place in above-mentioned oil seal structure frequently with the supporting use of motor the time, this had both increased the specific oil consumption of motor, and the while is befouling environment again.Become a problem of client's complaint, be badly in need of seeking better technological scheme and solve the pressurized machine leakage of oil.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of oil seal structure of turbosupercharger is provided, and has enlarged the drainback passage that flows out lubricant oil from thrust bearing, makes its oil return unimpeded; Simultaneously, because the iris action of oil baffle makes lubricant oil enter sealing system and reduces as much as possible; Anti-leakage of oil ability is significantly improved, and has solved the leakage of oil problem of pressurized machine.
Main solution of the present utility model is achieved in that
The utility model mainly adopts oil baffle to be contained on the sealing gland plate, seals up at axle seal ring is housed, and be pressed into the endoporus of sealing gland plate, and oil baffle is contained on the sealing gland plate.
Axle described in the utility model is sealed up and is provided with the hole.
Sealing gland plate described in the utility model is provided with annular groove.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; By increasing the improvement of oil baffle and sealing gland plate, enlarged the drainback passage that flows out lubricant oil from thrust bearing, make its oil return unimpeded; Simultaneously, because the iris action of oil baffle makes lubricant oil enter sealing system and reduces as much as possible, reduce to minimum; Anti-leakage of oil ability is significantly improved, and has solved the leakage of oil problem of pressurized machine; And the manufacture view of pressurized machine does not bring difficulty, but can bring the effect of environmental protection and saving lubricant oil to society, reduces the complaint of client to leakage of oil.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model oil baffle structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of oil baffle 1, sealing gland plate 2, axle envelope 3 and seal ring 4 etc.Adopt oil baffle 1 to be contained on the sealing gland plate 2, and adopt the method for flanging to be fixed on the sealing gland plate 2, described sealing gland plate 2 is provided with annular groove.Adorn a seal ring 4 on the axle envelope 3, described axle envelope 3 is provided with the hole; The endoporus that axle envelope after the assembling is pressed into sealing gland plate 1 is formed parts, the middle case and being pressed on the thrust bearing 5 of again these parts being packed into.
The utility model working principle:
The utility model utilizes its high speed rotating can throw the effect of oil, at first is that the oil thrower of axle envelope stops lubricant oil to enter sealing system.Entered sealing system if any a spot of oil,, entered in the narrow slit of an end face of envelope and the formation of sealing gland plate when oil drops down along the sealing gland plate.Because the axle sealing fixes on the axle of high speed rotating, oil can be dished out once more.If still have a spot of oil to enter axle envelope inside, because oil is sticking, its can be along with the rotation of axle envelope, and oil can be dished out by two rounds that axle is sealed up under action of centrifugal force.The outstanding end face of end face in the axle envelope and sealing gland plate forms a narrow slit again, plays barrier effect once more.Finally make the long-pending oil that enters the seal ring place minimum.
Because above-mentioned improvement, cause seldom at the long-pending oil at gas compressor end seal ring place.Like this, though the pressure in middle case greater than gas compressor pressure behind more for a long time, also can play good anti-leakage of oil ability.Even when leakage of oil takes place, also be that a spot of oil oozes out.
