Embodiment：
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
A kind of vehicle-mounted air compressor enclosure axis oil enveloping structure, includes the appearance of one end open, an end closure and all round closure
Cavity-like shell body 1, the closing of shell body 1 one end is provided with the through hole passed for rotor, and through hole bolt connection has shafting oil capsule body 2,
Sealing gasket 3 is installed in shafting oil capsule body 2.
Through hole screw thread is provided with screw shell 4, and the side that screw shell 4 is located at shell body cavity volume is provided with auxiliary seal pad
5, the side bolt that screw shell 4 is located at outside shell body cavity volume is provided with shafting oil capsule body 2, sets auxiliary seal pad to strengthen
Sealing effectiveness, and can first dismantle lower axle oil sealing housing screwing screw shell, then to thread bush again when repairing and changing
Sealing gasket in cylinder is changed.
Sealing gasket 3 and auxiliary seal pad 5 are rubber gasket.
The intermediate openings of sealing gasket 3 are horn-like, and loudspeaker big opening end is located at housing cavity volume one end, positioned at shell body cavity volume one
Hold as big opening end, so be easy to find accurately the opening of sealing gasket when rotor is passed outward from cavity volume one end；Through-hole wall has
It is provided with a coil spring 6 in the one circle groove concentric with through hole, groove, the inner side of spring 6 is provided with rubber plate face 7, and rubber plate face 7 is toward recessed
Notch both sides extend, and the glue of rubber plate face 7 is attached to outside groove mouth, and the face that rubber plate face 7 coordinates with sealing gasket 3 again is sawtooth
Face coordinates blend compounds water to paste, and the setting of serrated face can increase contact area, can so prevent from sealing gasket and shafting oil capsule
The gap location leakage of body, and when rotor runs at high speed generation circular runout, rotor squish sealing gasket, spring, which can be offset, to be turned
Sub- radial load, it is to avoid rotate for a long time and cause sealing gasket to wear and tear, greatly improve sealing gasket service life.
Shell body is cylinder.
Through-hole diameter is 20mm-35mm, and it is 32mm that through-hole diameter, which can be preferably,.
The shell body of original monoblock type, is all to install sealing gasket from cavity volume side when installing every time, then installs again small
End cap and big end cap make to form sealing space in cavity volume, small end cover and big end cap under must so being dismantled in maintenance, very numb
It is tired and original high to through hole requirement on machining accuracy, if the not high axle of precision can accelerate the abrasion to sealing gasket when running at high speed,
Using present split-type structural, sealing gasket is installed in shafting oil capsule body, the processing to through hole can be so substantially reduced
Precision, improves sealing gasket service life.
Tested for the big end cap before improvement, after improvement.
1st, experimental facilities
2nd, experimental principle
Shell body opening side of the present invention is installed after big end cap and small end cover so that sealing space is formed in cavity volume,
Then using escape pipe out of sealing gasket hole toward insertion in cavity volume, from air inlet pipe toward cavity volume in squeeze into nitrogen, make cavity volume internal pressure
Power is 1.5MPa, then seals air inlet, and pressurize simultaneously observes leakage situation；Simultaneously with the housing of original one piece casting type by upper
The method of stating is tested, and observes leakage situation.
3rd, test data is recorded
The test data of shell body originally, as shown in Table 1
Table one
Using present improvement shell body test data, as shown in Table 2
Table two
Contrasted from table one, table two, using after improvement shafting oil seal install, it is not only time saving, install, convenient disassembly and
Can be seen that according to data above does not influence original air-tightness not only, and air-tightness is more beneficial for a certain extent.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the simply explanation described in above-described embodiment and specification is originally
The principle of invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
