Abstract
The utility model provides an aviation fluoro-rubber leather cup with a compound lip. The leather cup comprises a fluoro-rubber leather cup body and a metallic frame located inside the fluoro-rubber leather cup body, wherein the compound lip consisting of two lips is arranged at a cutting edge of the fluoro-rubber leather cup body, and a ring-shaped oil storage groove is formed between the two lips. The utility model can prolong the working life thereof in a mechanical sealing working condition and reduce mechanical breakdowns caused by sealing failure, and has the advantages of high production efficiency and easy processing.
Description
Technical field:
The utility model relates to a kind of rubber cup, particularly be a kind of compound lip aviation fluorine rubber leather cup.
Background technique:
A kind of accurate complicated assembly parts that aviation fluorine rubber axle strip of paper used for sealing bowl is made up of metal frame, rubber cup body.Extensive use in mechanical seal.Be mainly used in the radial seal of axle and the space sealing less pressure gap.During work, the linear velocity that the leather cup lip is relative with axle is higher, and rotating speed is not waited by 5000～10000 commentaries on classics/min.The most common failure of leather cup is that the work lip is 45 along the axle sense of rotation and tears mostly.This tearing mainly is that friction temperature is bonded on the surface leather cup cutting edge, and " adhesion " phenomenon has taken place owing to produce " dry friction " of no film lubrication between leather cup cutting edge and the metal shaft, therefore caused tearing of cup packing lip.A traditional axle strip of paper used for sealing bowl is single lip, and processing method is a turning processing lip after the leather cup moulding, occurs the lip secondary operations easily and the outer circles deviation is bigger; Defective such as frictional force increase between lip and the seal shaft, the lip of leather cup does not have the oil storage function.Thereby traditional aviation fluorine rubber axle strip of paper used for sealing bowl operating life is not long, brings mechanical failure often because of seal failure.
The model utility content:
The purpose of this utility model is for a kind of operating life in the mechanical seal working state being provided, reducing the mechanical failure that causes because of seal failure, the compound lip aviation fluorine rubber leather cup of manufacturing efficiency height, easy processing.
The purpose of this utility model is achieved like this:
The compound lip aviation of the utility model fluorine rubber leather cup, comprise fluorine rubber leather cup body, be arranged in the metal frame of fluorine rubber leather cup body, it is characterized in that fluorine rubber leather cup body cutting edge place is by the compound lip of being made up of the twice lip, annular oil storage tank is arranged between the twice lip, the structure of compound lip make the inefficacy of fluorine rubber leather cup many ensure together, when one seal lip wherein cracks and lost efficacy, another road lip can also play the seal action the same with traditional rubber cup, the lubricant oil of storing can continue to make and forms lubricant film between lip and the running shaft in the oil storage tank, and the operating life of aviation fluorine rubber axle strip of paper used for sealing bowl lip under normal high speed rotating prolonged.
The shape of above-mentioned twice lip is respectively the fillet of band radian, and the face contact is changed in traditional line contact, under the oil film action of oil storage tank, makes the wear-out life of compound lip more permanent.
Above-mentioned oil storage tank sectional shape is a circular arc.
The long working life of the utility model in mechanical seal reduced the mechanical failure that causes because of seal failure, manufacturing efficiency height, easy processing.Verified that in installation test it is than 1.5 times of the long working lifes of traditional fluorine rubber leather cup.Manufacturing efficiency than traditional first moulding again secondary turning the method height 35%.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is compound lip structural representation.
Embodiment:
Referring to Fig. 1, Fig. 2, the compound lip aviation of present embodiment fluorine rubber leather cup comprises fluorine rubber leather cup body 1, is arranged in the metal frame 2 of fluorine rubber leather cup body.Fluorine rubber leather cup body cutting edge place is by the compound lip of being made up of twice lip 34.It is the annular oil storage tank 5 of circular arc that sectional shape is arranged between the twice lip.
Referring to Fig. 2, the shape of twice lip 3 is respectively the fillet of band radian.
Claims (3)
1. compound lip aviation fluorine rubber leather cup comprises fluorine rubber leather cup body, is arranged in the metal frame of fluorine rubber leather cup body, it is characterized in that by the compound lip of being made up of the twice lip, there is annular oil storage tank at fluorine rubber leather cup body cutting edge place between the twice lip.
2. the described compound lip aviation fluorine rubber leather cup of claim 1 is characterized in that the shape of twice lip is respectively the fillet of band radian.
3. claim 1 or 2 described compound lip aviation fluorine rubber leather cups is characterized in that the oil storage tank sectional shape is a circular arc.
