Description

Rack-type adjusting device with position change of backing bearing roller
Technical Field
The invention relates to the technical field of adjusting devices, in particular to a rack type adjusting device with a back lining bearing roller with a position changing function.
Background
The invention relates to the spatial positioning and adjustment of multi-roll (8-roll and over 8-roll) rolling mill backing bearing rolls in a frame. The positioning of the "backing bearing roll" consisting of several backing bearings in a cluster mill is the basis for the stability of the cluster mill roll train. The roll diameters of the individual layers of the roll system vary continuously due to variations in the thickness of the rolled workpiece, and due to wear of the roll system during operation and the grinding of the rolls from time to eliminate cracks in the roll surfaces. The spatial position of the backing bearing roll, which is the basis for the position of the roll system, in the rolling mill needs to be constantly adjusted.
The existing design is adjusted by the mandrel eccentricity of the backing bearing roll, see pennsheng '20-roll mill and high-precision cold-rolled strip production' 2007 edition of the publication of metallurgy industry.
During rolling, the back lining bearing roller is stressed greatly, and a large torsional moment can be generated by a small eccentric amount. Because the outer diameter of the backing bearing is far larger than the shaft diameter of the mandrel, namely the balancing moment arm is far smaller than the torsion moment arm, the clamping force of the eccentric mandrel needs to be quite large to balance the torsion moment. And the torsional stress borne by the mandrel is also large.
The invention utilizes the eccentricity of the outer circle and the inner hole of the saddle to balance the torsional force, thereby not only increasing the adjustment range of the backing bearing roller, but also thoroughly eliminating the torsional stress born by the core shaft and improving the space positioning and the adjustment working condition of the backing bearing roller.
