Abstract
The invention discloses a double-lip sealing ring for a rotary shaft of an air conditioner compressor. The double-lip sealing ring consists of a first sealing seat ring, a limit taper sleeve, a second sealing ring, a bearing tray and a bearing gasket; the limit taper sleeve, the second sealing ring, the bearing tray and the bearing gasket are arranged in the cavity of the first sealing seat ring in turn; and the sectional shape of a bearing lug boss ring is right-angled trapezoid, the right-angled waist is inside, and the oblique waist is outside. The sectional shape of the bearing lug boss ring is changed into the right-angled trapezoid from rectangle; and after the bearing lug boss ring is pressed, the radial component force of the pressure acted on the bearing lug boss ring is outward and has minimum influence on the limit taper sleeve, thus ensuring the shapes of sealing lips and the stability of tension, ensuring the sealing performance, eliminating the single offset phenomenon produced after a sealing lip belt is pressed and deformed, reducing the friction force between the sealing lip belt and the rotary shaft, prolonging the service life of the whole product and reducing the energy consumption.
Description
Technical field:
The present invention relates to a kind of air condition compressor obturator, relate in particular to the double-lip sealing ring that air conditioner compressed machine rotating main is used.
Background technique:
The used backbone sealing ring of the rotary main shaft of air condition compressor requires very high, it must be with the refrigeration agent in the air condition compressor, refrigeration oil and transferring elements are isolated, in case refrigeration agent and refrigeration oil seepage, the used backbone sealing ring of present air conditioner compressed machine rotating main is the double-lip seal structure, as shown in Figure 1, it is by first seal holder ring 1, spacing tapered sleeve 2, second seal ring 3, pressure-bearing pallet 4 and pressure-bearing packing ring 5 are formed, spacing tapered sleeve 2, second seal ring 3, pressure-bearing pallet 4 and pressure-bearing packing ring 5 are installed in the inner chamber of first seal holder ring 1 successively, described first seal holder ring 1 is by metal frame 11, sizing material outer ring 12, first envelope lip band 13, pressure-bearing boss circle 14 and pressure-bearing bent angle circle 15 are formed, the sectional shape of described pressure-bearing boss circle 14 is a rectangle, spacing tapered sleeve 2 is that sectional shape is the tapered sleeve part of " eight " word, the running shaft Spielpassung of the aperture of its little head end and air condition compressor, the external diameter of stub end is corresponding with the internal diameter of pressure-bearing boss circle 14; Second seal ring 3 is fixing by pressure-bearing pallet 4 and 5 compressings of pressure-bearing packing ring, and pressure-bearing pallet 4 and pressure-bearing packing ring 5 coat spacing by the extension of exposing of metal frame 11 by wrap direction.
In actual production process, pressure-bearing packing ring 5 is oppressed with the bending of bending floding machine in the extension of exposing of metal frame 11, make the seal holder ring 1 of winning, spacing tapered sleeve 2, second seal ring 3, pressure-bearing pallet 4 and pressure-bearing packing ring 5 are riveted into one, in roll extrusion riveted joint process, pressure-bearing boss circle 14 and pressure-bearing bent angle circle 15 in first seal holder ring 1 will be subjected to bigger pressure, and the mobility of the action direction of pressure is bigger, be easy to cause pressure-bearing boss circle 14 irregular compression displacement phenomenon to occur, can make inwardly local, local outside compression displacement phenomenon, make second seal ring, 3 seal lips the sealing tomography occur, cause the tension force and the shape instability of seal lip, direct inclusion uniformity between the seal lip of the influence first envelope lip band 13 and second seal ring 3 and the running shaft, both influence sealability, influenced working life again.This is to cause air condition compressor unstable with running shaft double-lipped sealing ring tightness energy, the main cause that working life is long.
Summary of the invention:
The purpose of this invention is to provide a kind of double-lip sealing ring for rotary shaft of air conditioner compressor, it is good seal performance not only, and long service life.
The technological scheme that the present invention takes is: a kind of double-lip sealing ring for rotary shaft of air conditioner compressor, it is by first seal holder ring, spacing tapered sleeve, second seal ring, pressure-bearing pallet and pressure-bearing packing ring are formed, spacing tapered sleeve, second seal ring, pressure-bearing pallet and pressure-bearing packing ring are installed in the inner chamber of first seal holder ring successively, described first seal holder ring is by metal frame, the sizing material outer ring, first envelope lip band, pressure-bearing boss circle, pressure-bearing bent angle circle, outer distortion cavity volume and internal strain cavity volume are formed, spacing tapered sleeve is that sectional shape is the tapered sleeve part of " eight " word, the rotary main shaft Spielpassung of the aperture of its little head end and air condition compressor, the external diameter of stub end is corresponding with the internal diameter of pressure-bearing boss circle; Second seal ring is fixing by pressure-bearing pallet and the compressing of pressure-bearing packing ring, pressure-bearing pallet and pressure-bearing packing ring coat spacing by the extension of exposing of metal frame by wrap direction, it is characterized in that: the sectional shape of described pressure-bearing boss circle is a right-angled trapezium, with the pairing waist of internal strain cavity volume be the right angle waist, with the pairing waist of outer distortion cavity volume be the hypotenuse waist.
Owing to change the sectional shape of pressure-bearing boss circle into right-angled trapezium by rectangle, behind the pressure-bearing boss circle pressurized, make that to act on its pressure component diametrically outside, influence to spacing tapered sleeve is minimum, thereby has guaranteed the shape of seal lip and the stability of tension force, can guarantee sealability, produce single phenomenon partially after eliminating sealing lip band compressive deformation again, reduce friction between sealing lip band and the running shaft, both prolonged the working life of entire product, reduced energy consumption again.Owing to the sealability instability of having eliminated double-lip sealing ring for rotary shaft of air conditioner compressor from structure, the cause of disease that working life is long.
