Abstract
A new sealing sleeve of a supercharger comprises a sealing sleeve body and two seal grooves, a shaft hole is arranged in the center of the sealing sleeve body and the shaft hole is a through hole. The two seal grooves of various shapes are positioned on an excircle of the sealing sleeve body, which can be rectangular grooves and dovetail grooves. The sealing sleeve body is an independent structure with a block ear, of which an excircle diameter is larger than the excircle diameter of the sealing sleeve body and a bevel is disposed on a superior angle part at the back of the block ear. The two seal grooves are sealed with double rings, so that the pressure on the sealing rings is reduced, the deformation of the sealing rings is prevented, the outgoing resistance of the oil leakage is increased, the sealability is intensified and the service life is prolonged. The block air is designed for limiting the back movement of an oil baffle disc and preventing the deformation of the oil baffle disc. The bevel is disposed on a superior angle part at the back of the block ear, which has the leading effect on the oil leakage, so that the oil into the back of the block ear can be thrown back to the oil chamber along the bevel under the rotating inertia, and accordingly the sealability of the sealing device is intensified.
Description
Technical field
The present invention relates to a kind of seal arrangement, relate in particular to a kind of pressurized machine novel seal cover that is arranged on compact car with the turbocharger air compressor end.
Background technique
Along with the develop rapidly of Domestic Automotive Industry and shipping industry, car engine and marine engine technology bring in constant renewal in to be regenerated, and technical merit improves constantly, pressurized machine as with the important body of Engine Matching, more and more play an important role.Pressurized machine is assembled by many component, and turbine shaft is one of them most important parts, and many parts of pressurized machine all are benchmark with the turbine shaft, is provided with to be installed on the turbine shaft.The turbine shaft rotating speed is very high, small sized turbine pressurized machine working speed is up to 260000r/min, so very high heat of friction-produced between the part, in order to guarantee the steadily normal of axle system motion, must be by lubricating oil to its lubricated cooling, guarantee that axle is a proper functioning, also guaranteed the proper functioning of pressurized machine simultaneously.But be adsorbed on fluid on axle system and other component under the effect of motional inertia to around scattering, if sealing system is bad, lubricant oil can outwards be scurried out along rotating shaft, the machine oil that enters gas compressor enters the engine cylinder burning with pressurized air, entering turbine box can burn with waste gas, the capital has increased the consumption of engine motor oil, and the blue cigarette that machine oil burning is simultaneously emerged can cause the engine exhaust emission index exceeding standard again.This is that the seal arrangement at two ends has proposed strict requirement to axle.Stuffing box gland is an indispensable part in the seal arrangement.At present, some that sell on the market, use are used for being a closure gasket groove on the stuffing box gland of the stuffing box gland of pressurized machine, particularly small-sized vehicle turbocharger, and sealing effect is not good enough, causing occurring the lubricating oil leakage problem in the pressurized machine using process, is the maximum problem of user vehicle reflection.And stuffing box gland high speed rotating under turbine shaft drives, exercise load is big, easily produces distortion, and the axis hole of stuffing box gland and peripheral serious wear can have a strong impact on the sealing of stuffing box gland.
Summary of the invention
The present invention has overcome the existing shortcoming of above-mentioned turbosupercharger, satisfies the special requirement of society to pressurized machine, and its structure is improved, and provides a kind of simple in structure, and low cost of manufacture is easy for installation, the pressurized machine stuffing box gland that sealability is good.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of pressurized machine stuffing box gland, mainly constitute by sealing body and seal groove, sealing body center is provided with axis hole, seal groove is arranged on the cylindrical of sealing body, wherein: described sealing body becomes independently integrative-structure, described seal groove is two, and described sealing body is provided with blocked ear.
For optimizing technique scheme, the measure of being taked also comprises:
The outside diameter of above-mentioned pressurized machine stuffing box gland blocked ear is greater than the outside diameter of sealing body.
Above-mentioned upper corner position, the pressurized machine stuffing box gland blocked ear back side is the inclined-plane.
Distance between two seal grooves of above-mentioned pressurized machine stuffing box gland is about a seal groove groove width.
The shape of above-mentioned pressurized machine stuffing box gland seal groove can be various.
The shape of above-mentioned pressurized machine stuffing box gland seal groove can be rectangle groove.
The shape of above-mentioned pressurized machine stuffing box gland seal groove can be dovetail groove.
By above narration, the present invention compared with prior art has the following advantages: 1. the split of parts such as sealing body and thrust plate design makes the sealing body become independently integrative-structure, simple in structure, reasonable in design, cost is low, has strengthened the practicability and the usability of stuffing box gland; 2. the design of double sealing groove, to axle is that sealed end carries out the dicyclo sealing, changed shortcomings such as a road sealing groove pressurized is excessive, yielding, sealing reduction, the employing of double sealing ring has reduced the seal groove pressure, also reduced simultaneously seal groove inner seal ring pressure, prevent sealing ring deformation, strengthened the resistance of going out of leakage of oil, strengthened the stuffing box gland overall tightness, prolong the working life of stuffing box gland and seal ring, guaranteed the sealing of pressurized machine axle head; 3. the design of blocked ear on the sealing body moves after having limited the oil baffle disc that is arranged on the stuffing box gland, prevents the oil baffle disc distortion; 4. the blocked ear outside diameter has further stopped the oil that drains to the blocked ear front through oil baffle disc greater than the outer diameter of sealing body, has stoped leaking outside of oil; 5. upper corner position in the blocked ear back side is the inclined-plane, leakage of oil through blocked ear, be rotated with the sealing body, the setting on inclined-plane, leading role has been played in leakage of oil, the oil that enters into the blocked ear back side is got rid of along inclined-plane, the blocked ear back side under the effect of rotator inertia get back in the oil pocket, prevent that leakage of oil from entering the axial clearance of sealing body and oil sealing cap, further strengthened the sealing of seal arrangement.
