Supporting roller split inner sleeve or split bearing assembled connecting device

Abstract

The apparatus for assembling the split inner bushing or bearing for support roll includes one shaping convex ring set on one shaft, one eccentric handle fixed on the shaft, one pair of clamping end caps for clamping the connected parts, one locating inner bushing to be set on the connected parts, and one auxiliary rule for defining the depth of the shaping convex ring. The shaping convex ring has end shape fitting the connected parts, and one bearing is set between the shaping convex ring and the shaft. The present invention has wide application, stable connecting performance, high assembling precise, high assembling strength and high assembling speed, and is suitable for batch production.

Description

technical field [0001] The invention relates to an assembling and connecting device, in particular to an assembling and connecting device for a backing roll split inner sleeve or a split bearing for a straightening machine. Background technique [0002] The rolling production lines of iron and steel enterprises all have the characteristics of high-speed production, continuous operation and high control precision, especially the finishing production line of hot rolling, as the last process of hot rolling process to control the quality of finished products, the performance of finishing straightening machine equipment, especially The performance of the support roll of the straightening machine directly affects the output and quality of the finished product. However, the oil stained coils caused by the finishing and leveling machine equipment are becoming increasingly obvious and prominent. In order to solve the oil pollution problem, the existing thick plate leveling machine su...

AI Technical Summary

Problems solved by technology

However, the oil stained coils caused by the finishing and leveling machine equipment are becoming increasingly obvious and prominent. In order to solve the oil pollution problem, the existing thick plate leveling machine support rolls adopt oil-proof support rolls, see figure 1 , figure 2 , there is a skeleton seal ring between the outer sleeve of the backup roll and the inner sleeve of the backup roll outside the rolling body, and the inner sleeve of the backup roll is fixed by the end cover

However, the maintenance and disassembly of the support roll is very inconvenient due to the limitation of the installation space of the support roll, and in actual production, in addition to the oily coils caused by the finishing and leveling machine equipment affecting product quality, iron oxide powder also It is easy to enter into the rolling body of the back-up roll, thus affecting the quality of the finished product

[0003] With the development of Baosteel’s back-up roll technology for straightening machines, Baosteel has developed a dust-proof back-up roll technology (ZL 200420082414.5) that can be quickly replaced for thick plate levelers, which overcomes the difficulty in disassembly and poor dust-proof performance of the existing back-up rolls defects, can realize quick disassembly and maintenance of backup rollers, good dustproof and sealing performance
