Embodiment Construction

[0027] The present invention will be described in detail below according to the accompanying drawings.

[0028] The rolling mill roll bearing flat-press combined assembly seal structure includes an upper roll and a lower roll. The upper roll and the lower roll respectively include a transmission end and an operation end. Bearing seat 1 on the end, and bearing seat 1 on the transmission end is installed with a bearing 36. The inner end cover 29 is installed on the side of the bearing 36 close to the upper roller surface. A sealing ring 28 is arranged between the bearing 36 and the upper roller of the largest diameter section. One end of the ring 28 is in contact with the bearing 36, and the other end is in contact with the side of the maximum diameter section of the upper roll. There are bolts 37 on the seal ring 28, and the seal ring 28 is connected to the support ring 27 through the bolts 37; on the other side of the center maximum diameter section There is an upper bearing s...

Abstract

The invention relates to a rolling mill roll bearing flat pressing combination assembling type sealing structure. The sealing structure comprises an upper roll and a lower roll, and the upper roll andthe lower roll both comprise transmission ends and operation ends; and a sealing ring is arranged between a bearing and the largest diameter section of the upper roll, one end of the sealing ring makes contact with the bearing, the other end of the sealing ring makes contact with the side surface of the largest diameter section of the upper roll, bolts are arranged on the sealing ring, and the sealing ring is connected to a supporting ring through the bolts. An original sealing structure which is a labyrinth waterproof double-framework encircling oil seal is changed and replaced with a flat pressing type seal, and the problem that during installation, rolls with dozens of tons collide with bearings with dozens of tons, the bearing sealing precision and the roll matching surface precisionare damaged is solved.

Description

technical field [0001] The invention relates to a large-scale rolling mill roll bearing used in the production of precision steel plates, in particular to a rolling mill roll bearing flat-press combined assembly type sealing structure, which adopts an integrally assembled flat-press type flexible seal to replace the original rigid encircling rolling mill roll waterproof sealing structure. Background technique [0002] In the production of precision steel plates, it is necessary to repeatedly roll the rough strip steel on the rolling mill. The high precision and heavy weight of the products are in short supply for modern technology. This kind of rolling mill needs to withstand thousands of tons of impact force, which is a large and important equipment. The rolling mill is set as two sets of back-up rolls up and down, that is, the upper back-up roll and the lower back-up roll. One end of the upper and lower support rollers is the driving side, and the other end is the operatin...
