The interaction strength of the first hard gasket and the second hard gasket is better, and the first hard gasket is adhered after the shaping, so that the formed flange position is more accurate.
In the concrete manufacturing process, the first hard gasket 3 and the second hard gasket 6 are paper gaskets cut from hard paper sheets. The paper gasket can fix the shape of the flanging parts at the two ends of the oil pocket body, and the flanging parts at the two ends are ensured to be smooth and not to be wrinkled.
In one embodiment of the present invention, as shown in fig. 3, the sealing member is a pad 4 of pure rubber disposed between the flange portion 2 and the flange 01, and the upper edge of the sealing tape 5 extends between the pad 4 of pure rubber and the oil pocket body 1 of the flange portion 2. The gap between the oil pocket body and the transmission shaft flange is sealed by the pure rubber gasket, and a certain buffering effect is achieved.
In one embodiment of the present invention, as shown in fig. 1 and 3, the oil pocket body 1 has a layered structure, and sequentially includes an aramid cloth cover 11, a cloth-sandwiched rubber cover 12, and a polyester cotton cloth cover 13 from outside to inside, where the cloth-sandwiched rubber cover 12 is used for bonding the outer aramid cloth cover 11 and the inner polyester cotton cloth cover 13; a supporting ring 7 is arranged in the middle position of the oil pocket body 1 and is used for supporting the oil pocket body 1 outside the transmission shaft gear joint 00 of the rolling mill; the supporting ring 7 is arranged between the polyester cotton cloth cover 13 and the cloth clamping rubber cover 12.

The protective adhesive tape can protect the flanging part of the oil-in-oil body, and has the function of sealing the air passage between the second hard gasket and the oil-in-oil body.
In the concrete manufacturing process, the processing dimensions of each part are as follows:
1. the thickness of the first hard gasket 3, the second hard gasket 6 and the pure rubber gasket 4 is between 1mm and 4 mm. When the thickness of the pure rubber pad and the paper gasket is lower than 1mm, the sealing function is lost, and an effective sealing environment cannot be formed; when the thickness of the pure rubber pad and the paper pad is higher than 4mm, the pad is crushed due to too large compression, so that oil leakage is generated.
The first hard gasket 3, the second hard gasket 6 and the pure rubber gasket 4 have the inner diameter of 290-320mm and the outer diameter of 360-380 mm. When the inner diameters of the first hard gasket 3, the second hard gasket 6 and the pure rubber gasket 4 are smaller than 290mm or the outer diameter is larger than 380mm, the pure rubber gasket cannot be assembled on equipment due to the fact that the inner diameters are too small or the outer diameters are too large; when the inner diameter is larger than 320mm or the outer diameter is smaller than 360mm, the through holes cannot be machined at the correct positions due to the fact that the positions of the bolt holes on the end flanges of the transmission shafts are fixed. The above dimensions are designed according to existing rolling mill equipment. Of course, the specific diameter can also be designed according to the specific dimensions of the rolling mill installation.
2. The diameter of the through hole on the flanging part and the first hard gasket is 9-15 mm. When the through holes are machined, the through holes are matched with the through holes on the flanges at the end parts of the transmission shafts.
3. The thickness of the aramid cloth cover 11, the cloth-clamping rubber cover 12 and the polyester cotton cloth cover 13 is between 0.5 and 2 mm. When the thickness of the terylene cloth layer, the adhesive cloth layer and the aramid cloth layer is lower than 0.5mm, the problem of stress damage in the use process can be caused by the excessively thin thickness; when the thickness of the terylene cloth layer, the adhesive cloth layer and the aramid cloth layer is larger than 2mm, the qualified shape cannot be ensured in the processing process due to the excessive thickness, so that the whole product is deformed.
The circumference of the aramid cloth cover 11, the cloth-clamping rubber cover 12 and the polyester cotton cloth cover 13 is 950-1100mm, and the height is 220-300 mm. When the circumference is smaller than 950mm, the whole product is seriously deformed and cannot be used due to the too small inner diameter after assembly; when the circumference is larger than 1000mm, wrinkles are generated due to the overlarge inner diameter after assembly, so that the appearance is affected. When the height is smaller than 220mm, the assembled height of each layer is smaller than the minimum required by assembly, and the assembled layers cannot be assembled; when the height is greater than 300mm, the oversized height of each layer after the assembly can lead to the serious fold of product after the assembly, makes inside unable effectual oil storage environment of formation, has reduced the oil storage, influences the lubrication of joint position.
As above, the above dimensions are designed according to existing rolling mill equipment. Of course, the specific perimeter and height can also be designed according to the specific dimensions of the rolling mill equipment.
4. The thickness of the protective adhesive tape 8 is between 0.3 and 1 mm. When the thickness of the outer layer protective adhesive tape is smaller than 0.3mm, the adhesive tape cannot be processed; and greater than 1mm affects the thickness of the flange after assembly.
The circumference of the protective tape 8 is 950-1000mm and the height is 30-60 mm. When the width is smaller than 30mm, the area of the coated oil pocket body is too small to protect the oil pocket body; when the width is greater than 60mm, the area of cladding oil pocket body is too big, can influence the state that the oil pocket body is bloated because of centrifugal force when rotating, reduces the life of oil pocket body.
The principles and embodiments of the present invention have been described herein with reference to specific examples, the description of which is intended only to facilitate an understanding of the method of the present invention and its core ideas. It should be noted that it will be apparent to those skilled in the art that various modifications and adaptations of the invention can be made without departing from the principles of the invention and these modifications and adaptations are intended to be within the scope of the invention as defined in the following claims.
