Problems solved by technology

Its disadvantages are: in the actual use process, after the water seal is installed on the end face of the sealing cover, the surface of the water seal appears S-shaped. The reason is that the water seal is a rubber body, which is fastened by a limited number of copper screws. It is difficult to achieve a tight fit between them, and there will be unevenness, forming a large gap, so that water, impurities, iron scale, etc. In severe cases, it will also cause a major accident in which the entire rolling line is shut down, resulting in large economic losses

Embodiment Construction

[0011] According to the attached figure 1 Explain the present invention in detail;

[0012] figure 1 with figure 2 As shown in the sealing structure, it has a round rubber 3 between the sealing cover 2 and the sealing cover which is bolted on the bearing seat 1, and is installed between the sealing cover 2, the taper sleeve 10, the bushing 11 and the roll neck of the roll 12 The foot seal 4, the sealing ring 5 installed on the foot seal 4, the water seal device 6 on the end face of the sealing cover 2 and embedded in the sealing groove of the end face of the sealing cover, the sealing cover 2, the foot seal 4, The cavity between the roll 12 and the water seal 6 is also equipped with an aluminum ring device 7 that forms a sealed water seal. It is composed of an aluminum ring and a cushion pad 15. The cushion pad 15 is installed in the hole on the aluminum ring and attached to The end surface of the roll 12. The water sealing device 6 is also provided with a pressing ring 8 and ...

Abstract

The invention relates to a sealing structure, which comprises a bearing seat, a sealing cover, a round rubber, a taper sleeve, a bushing, a roller, a water sealing device and the like, wherein an aluminum ring device for forming water seal is arranged in the cavity among the sealing cover, a foot-shaped seal, the roller and the water sealing device. According to the present invention, the sealingstructure can effectively prevent cooling liquids and pollutants from entering bearings, and effectively prevent the oil leakage inside bearings; the water seal can be used in oil film bearing structures with different specifications so as to reduce the production cost; and the sealing structure has strong water sealing property, such that the defects of water entering, pollutants and the like ofthe original structure can be substantially improved, the accident that the whole rolling production line cannot work normally due to the entering of the water in the bearing can be avoided, and the service life of the oil film bearing can be improved.

Description

Technical field [0001] The invention belongs to the field of rolling mill bearings for rolling metal strips, and particularly relates to a sealing structure. Background technique [0002] At present, the sealing device used in the roller seal bearing is mainly composed of a sealing cover, an aluminum ring device, a foot seal, a sealing ring, and a water seal. The sealing cover is equipped with round rubber, which is installed on the end surface of the bearing seat by screws, the foot seal is installed on the sealing surface, the sealing ring is installed in the foot seal, the aluminum ring device is embedded on the side of the water sealing limb of the foot seal, and the water seal Tighten the end face of the sealing cover with a limited number of copper screws. They are combined with bearing seat, taper sleeve, bushing and roller to seal oil and water. The disadvantage is that in actual use, after the water seal is installed on the end face of the sealing cover, the surface of...
