The interaction strength of the first hard gasket and the second hard gasket is better, the first hard gasket is bonded after the shape is set, and the position of the formed flange is more accurate.
During specific manufacturing, the first hard gasket 3 and the second hard gasket 6 are both paper gaskets cut from hard paper sheets. The paper gasket can fix the shapes of the flanging parts at the two ends of the oil package body, and the flanging parts at the two ends are smooth and not wrinkled.

The pure rubber gasket is used for sealing a gap between the oil pocket body and the transmission shaft flange and plays a certain buffering role.
In a specific embodiment of the present invention, as shown in fig. 1 and 3, the oil bag body 1 is a layered structure, and sequentially comprises an aramid fabric sleeve 11, a fabric-sandwiched rubber sleeve 12 and a polyester-cotton fabric sleeve 13 from outside to inside, wherein the fabric-sandwiched rubber sleeve 12 is used for bonding the aramid fabric sleeve 11 on the outer layer and the polyester-cotton fabric sleeve 13 on the inner layer; a support ring 7 is arranged in the middle of the oil pocket body 1 and used for supporting the oil pocket body 1 outside a transmission shaft gear joint 00 of a rolling mill; the support ring 7 is arranged between the polyester cotton cloth cover 13 and the cloth clamping rubber cover 12. During the specific manufacturing, the cloth clamping rubber sleeve 12 is a two-layer rubber sleeve, and the aramid fiber cloth sleeve 11 is two layers; the support ring 7 is a stainless steel ring and can be sewn in the cloth clamping rubber sleeve and the polyester cotton cloth sleeve. The inner diameter of the oil pocket body is determined by the sewn stainless steel ring, so that the oil pocket body is supported, and meanwhile, the inner polyester cotton cloth sleeve has a certain dustproof filtering effect; the middle two layers of cloth-sandwiched rubber sleeves are mainly used for sealing gear oil, and the outer layers of aramid cloth sleeves are mainly dustproof and antifouling and provide excellent anti-flex effect. The oil bag body with the structure can adapt to a complex working condition environment, is not easy to age and damage, has excellent bending resistance, can greatly reduce the replacement frequency, and saves manpower and material resources.
As a preferable scheme, as shown in fig. 1 and 3, a protective adhesive tape 8 is arranged at a bent part on the inner side of the flanging part 2, the protective adhesive tape 8 is adhered to the outer part of the aramid cloth cover 11, and one end of the protective adhesive tape 8 extends to a position between the first hard gasket 3 and the second hard gasket 6. The protective adhesive tape can be used for protecting the flanging part of the oil pack body, and the air passage between the second hard gasket and the oil pack body is sealed.
During the specific manufacturing, the processing dimensions of each part are as follows:
1. the thicknesses of the first hard gasket 3, the second hard gasket 6 and the pure rubber gasket 4 are all between 1 and 4 mm. When the thickness of the pure rubber mat and the paper gasket is less 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 much compression, so that oil leakage is generated.
The inner diameters of the first hard gasket 3, the second hard gasket 6 and the pure rubber gasket 4 are between 290 and 320mm, and the outer diameters are between 360 and 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 diameters of the first hard gasket, the second hard gasket and the pure rubber gasket are larger than 380mm, the first hard gasket, the second hard gasket and 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 internal diameter is greater than 320mm or the external diameter is less than 360mm, the through hole can not be processed at the correct position due to the bolt hole position fixing on the flange at the end part of the transmission shaft. 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 plant.
2. The diameter of the through holes on the flanging part and the first hard gasket is between 9 and 15 mm. When the through hole is processed, the through hole is matched with the through hole on the flange at the end part of the transmission shaft.
3. The thickness of the aramid cloth cover 11, the cloth-sandwiched rubber cover 12 and the polyester cotton cloth cover 13 is 0.5-2 mm. When the thicknesses of the polyester cloth layer, the rubber cloth layer and the aramid cloth layer are less than 0.5mm, the problem of stress damage in the use process can be caused due to the excessively thin thicknesses; when the thickness of dacron cloth layer, rubberized fabric layer and aramid fiber cloth layer is greater than 2mm, can lead to whole product deformation because of the unable qualified shape of assurance of thickness excess in the course of working.
The circumferences of the aramid cloth sleeve 11, the cloth-sandwiched rubber sleeve 12 and the polyester cotton cloth sleeve 13 are between 950 and 1100mm, and the heights are between 220 and 300 mm. When the circumference is less than 950mm, the product is seriously deformed and cannot be used due to the over-small inner diameter after assembly; when the circumference is larger than 1000mm, the appearance is affected by wrinkles generated due to an excessively large inner diameter after assembly. When the height is less than 220mm, the height dimension of each assembled layer is less than the minimum dimension required by assembly, and the assembled layers cannot be assembled; when highly being greater than 300mm, the height dimension after each layer equipment is too big can lead to the serious fold to appear after the product assembly, makes inside unable effectual oil storage environment that forms, has reduced the oil storage capacity, influences the lubrication of joint position.
As above, the above dimensions are designed according to existing rolling mill equipment. Of course, the specific circumference and height can also be designed according to the specific dimensions of the rolling mill plant.
4. The thickness of the protective adhesive plaster 8 is between 0.3 and 1 mm. When the thickness of the outer-layer protective adhesive tape is less than 0.3mm, the adhesive tape cannot be processed; and greater than 1mm affects the thickness of the assembled flange.
The circumference of the protective adhesive tape 8 is between 950mm and 1000mm, and the height is between 30mm and 60 mm. When the width is less than 30mm, the area of the coated oil pocket body is too small, and the oil pocket body cannot be protected; when the width is larger than 60mm, the area of the coating oil pocket body is too large, the state of the oil pocket body which is expanded due to centrifugal force when the oil pocket body rotates can be influenced, and the service life of the oil pocket body is shortened.
The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
